(This introduction was written for a British 1940 reprint of DE RE MILITARI. Author unknown.)

The most influential military treatise in the western world from Roman times to the 19th Century was Vegetius' DE RE MILITARI. Its impressions on our own traditions of discipline and organization are everywhere evident.

The Austrian Field Marshal, Prince de Ligne, as late as 1770, called it a golden book and wrote: "A God, said Vegetius, inspired the legion, but for myself, I find that a God inspired Vegetius." Richard Coeur de Lion carried DE RE MILITARI everywhere with him in his campaigns, as did his father, Henry II of England. Around 1000 A. D. Vegetius was the favorite author of Foulques the Black, the able and ferocious Count of Anjou. Numerous manuscript copies of Vegetius circulated in the time of Charlemagne and one of them was considered a necessity of life by his commanders. A manuscript Vegetius was listed in the will of Count Everard de Frejus, about 837 A. D., in the time of Ludwig the Just.

In his Memoirs, Montecuculli, the conqueror of the Turks at St. Gotthard, wrote: "However, there are spirits bold enough to believe themselves great captains as soon as they know how to handle a horse, carry a lance at charge in a tournament, or as soon as they have read the precepts of Vegetius." Such was the reputation of Vegetius for a thousand years.

Manuscript copies dating from the 10th to the 15th centuries are extant to the number of 150. DE RE MILITARI was translated into English, French, and Bulgarian before the invention of printing. The first printed edition was made in Utrecht in 1473. It was followed in quick succession by editions in Cologne, Paris and Rome. It was first published in English by Caxton, from an English manuscript copy, in 1489.

Flavius Vegetius Renatus was a Roman of high rank. In some manuscripts he is given the title of count. Raphael of Volterra calls him a Count of Constantinople. Little is known of his life. It is apparent from his book that he had not had extensive practical experience as a soldier.. He states quite frankly that his purpose was to collect and synthesize from ancient manuscripts and regulations the military customs and wisdom that made ancient Rome great. According to his statement, his principal sources were Cato the Elder, Cornelius Celsus, Paternus, Frontinus, and the regulations and ordinances of Augustus, Trajan and Hadrian.

The Emperor Valentinian, to whom the book is dedicated, is believed to be the second emperor of that name. He evidently was not Valentinian I since his successor, Gratian, is named in the book. Between the reign of Valentinian II and Valentinian III, Rome was taken and burned by Alaric, King of the Goths, an event that unquestionably would have been mentioned had it occurred before the book was written. Vegetius mentions the defeat of the Roman armies by the Goths, but probably refers to the battle of Adrianople where Valens, the colleague of Valentinian I, was killed.

It is a paradox that DE RE MILITARI, which was to become a military bible for innumerable generations of European soldiers, was little used by the Romans for whom it was written. The decay of the Roman armies had progressed too far to be arrested by Vegetius' pleas for a return to the virtues of discipline and courage of the ancients. At the same time Vegetius' hope for a revival of the ancient organization of the legion was impracticable. Cavalry had adopted the armor of the foot soldier and was just commencing to become the principal arm of the military forces. The heavy armed foot-soldier, formerly the backbone of the legion, was falling a victim of his own weight and immobility, and the light-armed infantry, unable to resist the shock of cavalry, was turning more and more to missile weapons. By one of the strange mutations of history, when later the cross-bow and gun-powder deprived cavalry of its shock-power, the tactics of Vegetius again became ideal for armies, as they had been in the times from which he drew his inspiration.

Vegetius unceasingly emphasized the importance of constant drill and severe discipline and this aspect of his work was very tiresome to the soldiers of the middle ages, the feudal system lending itself but poorly to discipline. "Victory in war," he states in his opening sentence, "does not depend entirely upon numbers or mere courage; only skill and discipline will insure it." His first book is devoted to the selection, training and discipline of recruits. He insists upon the utmost meticulousness in drill. "No part of drill is more essential in action than for soldiers to keep their ranks with the greatest exactness." His description of the many arms which the Roman soldier was required to become expert in reminds one of the almost innumerable duties of the present day infantryman. Recruits were to be hardened so as to be able to march twenty miles in half a summer's day at ordinary step and twenty-four miles at quick step. It was the ancient regulation that practice marches of this distance must be made three times a month.

The second book deals with the organization and officers of the legion, the ancient system of promotion, and how to form the legion for battle. We find the Romans provided for soldier's deposits, just as is done in the American army today; that guard and duty rosters were kept in those days as now; and that the Roman system of guard duty is only slig.htly different from our manual for interior guard duty. The field music is described and is an ornamental progenitor of that in use in United States. The legion owed its success, according to Vegetius, to its arms and its machines, as well as to the bravery of its soldiers. The legion had fifty-five ballista for throwing darts and ten onagri, drawn by oxen, for throwing stones. Every legion carried its ponton equipment, "small boats hollowed out of a single piece of cimber, with long cables or chains to fasten them together." And in addition were "whatever is necessary for every kind of service, that the encampments may have all the strength and conveniences of a fortified city." Trains of workmen were provided to perform all the duties now performed by the various services in armies.

The third book deals with tactics and strategy and it was this portion of Vegetius that influenced war in the Middle Ages so greatly. He explains the use of reserves, attributing this invention to the Spartans, from whom the Romans adopted it. "It is much better to have several bodies of reserves than to extend your front too much" - an injunction as good today as when it was written. Encircling pursuit is described. The terrain is not overlooked. "The nature of the ground is often of more consequence than courage." The enemy should be estimated carefully. "It is essential to know the character of the enemy and of their principal officers-whether they be rash or cautious, enterprising or timid, whether they fight from careful calculation or from chance."

Vegetius' work is filled with maxims that have become a part of our everyday life. "He, therefore, who aspires to peace should prepare for war." "The ancients preferred discipline to numbers." "In the midst of peace, war is looked upon as an object too distant to merit consideration." "Few men are born brave; many become so through training and force of discipline."

Vegetius was a reformer who attempted to restore the degenerate Romans of the 4th Century to the military virtues of the ancients, whom he never ceases to laud. His little book was made short and easy to read, so as not to frighten, by a too arduous text, the readers whom he hoped to convince. He constantly gives the example of the " Ancients" to his contemporaries. The result is a sort of perfume of actuality, which had much to do with his success. It still is interesting reading and still is the subject of modern commentaries. No less than forty have appeared in Germany in the 19th and 20th centuries. Revue Mititare Generate (France) and our own Infantry Journal carried articles on Vegetius in 1938. Dankfried Schenk published an interesting article in Klio in 1930, which gives Vegetius the highest place among the writers of his time.

The present edition includes the first three books of Vegetius' work, omitting only repetitions. The fourth and fifth books, both very brief, deal with the attack and defense of fortified places and with naval operations. These are of interest only to military antiquarians and for that reason have not been included. The present translation was made by Lieutenant John Clarke and published in London in 1767. It is the best available in English and has been edited only to the minimum extent necessary to conform to modern usage.

An excellent discussion of Vegetius can be found in Warfare, by Spaulding, Nickerson and Wright, page 294, et sequens, Harcourt Brace & Co., 1925. Delpech, La Tactique au 13me Siecte, Paris, 1886, gives the best account of the influence of Vegetius on European military thought. Hans Delbruck's discussion of Vegetius in Geschichte der Kriegskunft, Vol. II, Berlin, 1921, although brief, is very acute.

To the Emperor Valentinian

It has been an old custom for authors to offer to their Princes the fruits of their studies in belles letters, from a persuasion that no work can be published with propriety but under the auspices of the Emperor, and that the knowledge of a Prince should be more general, and of the most important kind, as its influence is felt so keenly by all his subjects. We have many instances of the favorable reception which Augustus and his illustrious successors conferred on the works presented to them; and this encouragement of the Sovereign made the sciences flourish. The consideration of Your Majesty's superior indulgence for attempts of this sort, induced me to follow this example, and makes me at the same time almost forget my own inability when compared with the ancient writers. One advantage, however, I derive from the nature of this work, as it requires no elegance of expression, or extraordinary share of genius, but only great care and fidelity in collecting and explaining, for public use, the instructions and observations of our old historians of military affairs, or those who wrote expressly concerning them.

My design in this treatise is to exhibit in some order the peculiar customs and usages of the ancients in the choice and discipline of their new levies. Nor do I presume to offer this work.to Your Majesty from a supposition that you are not acquainted with every part of its contents; but that you may see that the same salutary dispositions and regulations which your own wisdom prompts You to establish for the happiness of the Empire, were formerly observed by the founders thereof; and that Your Majesty may find with ease in this abridgement whatever is most useful on so necessary and important a subject.

Book I: The Selection and Training of New Levies

THE ROMAN DISCIPLINE THE CAUSE OF THEIR GREATNESS

Victory in war does not depend entirely upon numbers or mere courage; only skill and discipline will insure it. We find that the Romans owed the conquest of the world to no other cause than continual military training, exact observance of discipline in their camps and unwearied cultivation of the other arts of war. Without these, what chance would the inconsiderable numbers of the Roman armies have had against the multitudes of the Gauls? Or with what success would their small size have been opposed to the prodigious stature of the Germans? The Spaniards surpassed us not only in numbers, but in physical strength. We were always inferior to the Africans in wealth and unequal to them in deception and stratagem. And the Greeks, indisputably, were far superior to us in skill in arts and all kinds of knowledge.

But to all these advantages the Romans opposed unusual care in the choice of their levies and in their military training. They thoroughly understood the importance of hardening them by continual practice, and of training them to every maneuver that might happen in the line and in action. Nor were they less strict in punishing idleness and sloth. The courage of a soldier is heightened by his knowledge of his profession, and he only wants an opportunity to execute what he is convinced he has been perfectly taught. A handful of men, inured to war, proceed to certain victory, while on the contrary numerous armies of raw and undisciplined troops are but multitudes of men dragged to slaughter.

THE SELECTION OF RECRUITS

To treat our subject with some method, we shall first examine what provinces or nations are to be preferred for supplying the armies with recruits. It is certain that every country produces both brave men and cowards; but it is equally as certain that some nations are naturally more warlike than others, and that courage, as well as strength of body, depends greatly upon the influence of the different climates.

We shall next examine whether the city or the country produces the best and most capable soldiers. No one, I imagine, can doubt that the peasants are the most fit to carry arms for they from their infancy have been exposed to all kinds of weather and have been brought up to the hardest labor. They are able to endure the greatest heat of the sun, are unacquainted with the use of baths, and are strangers to the other luxuries of life. They are simple, content with little, inured to all kinds of fatigue, and prepared in some measure for a military life by their continual employment in their country-work, in handling the spade, digging trenches and carrying burdens. In cases of necessity, however, they are sometimes obliged to make levies in the cities. And these men, as soon as enlisted, should be taught to work on entrenchments, to march in ranks, to carry heavy burdens, and to bear the sun and dust. Their meals should be coarse and moderate; they should be accustomed to lie sometimes in the open air and sometimes in tents. After this, they should be instructed in the use of their arms. And if any long expedition is planned, they should be encamped as far as possible from the temptations of the city. By these precautions their minds, as well as their bodies, will properly be prepared for the service.

I realize that in the first ages of the Republic, the Romans always raised their armies in the city itself, but this was at a time when there were no pleasures, no luxuries to enervate them. The Tiber was then their only bath, and in it they refreshed themselves after their exercises and fatigues in the field by swimming. In those days the same man was both soldier and farmer, but a farmer who, when occasion arose, laid aside his tools and put on the sword. The truth of this is confirmed by the instance of Quintius Cincinnatus, who was following the plow when they came to offer him the dictatorship. The chief strength of our armies, then, should be recruited from the country. For it is certain that the less a man is acquainted with the sweets of life, the less reason he has to be afraid of death.

THE PROPER AGE FOR RECRUITS

If we follow the ancient practice, the proper time for enlisting youth into the army is at their entrance into the age of puberty. At this time instructions of every kind are more quickly imbibed and more lastingly imprinted on the mind. Besides this, the indispensable military exercises of running and leaping must be acquired before the limbs are too much stiffened by age. For it is activity, improved by continual practice, which forms the useful and good soldier. Formerly, says Sallust, the Roman youth, as soon as they were of an age to carry arms, were trained in the Strictest manner in their camps to all the fatigues and exercises of war. For it is certainly better that a soldier, perfectly disciplined, should, through emulation, repine at his not being yet arrived at a proper age for action, than have the mortification of knowing it is past. A sufficient time is also required for his instruction in the different branches of the service. It is no easy matter to train the horse or foot archer, or to form the legionary soldier to every part of the drill, to teach him not to quit his post, to keep ranks, to take a proper aim and throw his missile weapons with force, to dig trenches, to plant palisades, how to manage his shield, glance off the blows of the enemy, and how to parry a stroke with dexterity. A soldier, thus perfect in his business, so far from showing any backwardness to engage, will be eager for an opportunity of signaling himself.

THEIR SIZE

We find the ancients very fond of procuring the tallest men they could for the service, since the standard for the cavalry of the wings and for the infantry of the first legionary cohorts was fixed at six feet, or at least five feet ten inches. These requirements might easily be kept up in those times when such numbers followed the profession of arms and before it was the fashion for the flower of Roman youth to devote themselves to the civil offices of state. But when necessity requires it, the height of a man is not to be regarded so much as his strength; and for this we have the authority of Homer, who tells us that the deficiency of stature in Tydeus was amply compensated by his vigor and courage.

SIGNS OF DESIRABLE QUALITIES

Those employed to superintend new levies should be particularly careful in examining the features of their faces, their eyes, and the make of their limbs, to enable them to form a true judgment and choose such as are most likely to prove good soldiers. For experience assures us that there are in men, as well as in horses and dogs, certain signs by which their virtues may be discovered. The young soldier, therefore, ought to have a lively eye, should carry his head erect, his chest should be broad, his shoulders muscular and brawny, his fingers long, his arms strong, his waist small, his shape easy, his legs and feet rather nervous than fleshy. When all these marks are found in a recruit, a little height may be dispensed with, since it is of much more importance that a soldier should be strong than tall.

TRADES PROPER FOR NEW LEVIES

In choosing recruits regard should be given to their trade. Fishermen, fowlers, confectioners, weavers, and in general all whose professions more properly belong to women should, in my opinion, by no means be admitted into the service. On the contrary, smiths, carpenters, butchers, and huntsmen are the most proper to be taken into it. On the careful choice of soldiers depends the welfare of the Republic, and the very essence of the Roman Empire and its power is so inseparably connected with this charge, that it is of the highest importance not to be intrusted indiscriminately, but only to persons whose fidelity can be relied on. The ancients considered Sertorius' care in this point as one of the most eminent of his military qualifications. The soldiery to whom the defense of the Empire is consigned and in whose hands is the fortune of war, should, if possible, be of reputable families and unexceptionable in their manners. Such sentiments as may be expected in these men will make good soldiers. A sense of honor, by preventing them from behaving ill, will make them victorious.

But what good can be expected from a man by nature a coward, though ever so well disciplined or though he has served ever so many campaigns? An army raised without proper regard to the choice of its recruits was never yet made good by length of time; and we are now convinced by fatal experience that this is the source of all our misfortunes. So many defeats can only be imputed to the effects of a long peace which has made us negligent and careless in the choice of our levies and to the inclination so prevalent among the better sort in preferring the civil posts of the government to the profession of arms and to the shameful conduct of the superintendents, who, through interest or connivance, accept many men which those who are obliged to furnish substitutes for the army choose to send, and admit such men into the service as the masters themselves would not even keep for servants. Thus it appears that a trust of such importance should be committed to none but men of merit and integrity.

THE MILITARY MARK

The recruit, however, should not receive the military mark* as soon as enlisted. He must first be tried if fit for service; whether he has sufficient activity and strength; if he has capacity to learn his duty; and whether he has the proper degree of military courage. For many, though promising enough in appearance, are found very unfit upon trial. These are to be rejected and replaced by better men; for it is not numbers, but bravery which carries the day.

After their examination, the recruits should then receive the military mark, and be taught the use of their arms by constant and daily exercise. But this essential custom has been abolished by the relaxation introduced by a long peace. We cannot now expect to find a man to teach what he never learned himself. The only method, therefore, that remains of recovering the ancient customs is by books, and by consulting the old historians. But they are of little service to us in this respect, as they only relate the exploits and events of wars, and take no notice of the objects of our present enquiries, which they considered as universally known.

INITIAL TRAINING

The first thing the soldiers are to be taught is the military step, which can only be acquired by constant practice of marching quick and together. Nor is anything of more consequence either on the march or in the line than that they should keep their ranks with the greatest exactness. For troops who march in an irregular and disorderly manner are always in great danger of being defeated. They should march with the common military step twenty miles in five summer-hours, and with the full step, which is quicker, twenty-four miles in the same number of hours. If they exceed this pace, they no longer march but run, and no certain rate can be assigned.

But the young recruits in particular must be exercised in running, in order to charge the enemy with great vigor; occupy, on occasion, an advantageous post with greater expedition, and prevent the enemy in their designs upon the same; that they may, when sent to reconnoiter, advance with speed, return with greater celerity and more easily come up with the enemy in a pursuit.

Leaping is another very necessary exercise, to enable them to pass ditches or embarrassing eminences of any kind without trouble or difficulty. There is also another very material advantage to be derived from these exercises in time of action; for a soldier who advances with his javelin,.running and leaping, dazzles the eyes of his adversary, strikes him with terror, and gives him the fatal stroke before he has time to put himself on his defense. Sallust, speaking of the excellence of Pompey the Great in these particulars, tells us that he disputed the superiority in leaping with the most active, in running with the most swift, and in exercises of strength with the most robust. Nor would he ever have been able to have opposed Serrorius with success, if he had not prepared both himself and his soldiers for action by continual exercises of this sort.

TO LEARN TO SWIM

Every young soldier, without exception, should in the summer months be taught to swim; for it is sometimes impossible to pass rivers on bridges, but the flying and pursuing army both are often obliged to swim over them. A sudden melting of snow or fall of rain often makes them overflow their banks, and in such a situation, the danger is as great from ignorance in swimming as from the enemy. The ancient Romans, therefore, perfected in every branch of the military art by a continued series of wars and perils, chose the Field of Mars as the most commodious for their exercises on account of its vicinity to the Tiber, that the youth might therein wash off the sweat and dust, and refresh themselves after their fatigues by swimming. The cavalry also as well as the infantry, and even the horses and the servants of the army should be accustomed to this exercise, as they are all equally liable to the same accidents.

THE POST EXERCISE

We are informed by the writings of the ancients that, among their other exercises, they had that of the post. They gave their recruits round bucklers woven with willows, twice as heavy as those used on real service, and wooden swords double the weight of the common ones. They exercised them with these at the post both morning and afternoon.

This is an invention of the greatest use, not only to soldiers, but also to gladiators. No man of either profession ever distinguished himself in the circus or field of battle, who was not perfect in this kind of exercise. Every soldier, therefore, fixed a post firmly in the ground, about the height of six feet. Against this, as against a real enemy, the recruit was exercised with the above mentioned arms, as it were with the common shield and sword, sometimes aiming At the head or face, sometimes at the sides, at others endeavoring to strike at the thighs or legs. He was instructed in what manner to advance and retire, and in short how to take every advantage of his adversary; but was thus above all particularly cautioned not to lay himself open to his antagonist while aiming his stroke at him.

NOT TO CUT, BUT TO THRUST WITH THE SWORD

They were likewise taught not to cut but to thrust with their swords. For the Romans not only made a jest of those who fought with the edge of that weapon, but always found them an easy conquest. A stroke with the edges, though made with ever so much force, seldom kills, as the vital parts of the body are defended both by the bones and armor. On the contrary, a stab, though it penetrates but two inches, is generally fatal. Besides in the attitude of striking, it is impossible to avoid exposing the right arm and side; but on the other hand, the body is covered while a thrust is given, and the adversary receives the point before he sees the sword. This was the method of fighting principally used by the Romans, and their reason for exercising recruits with arms of such a weight at first was, that when they came to carry the common ones so much lighter, the greater difference might enable them to act with greater security and alacrity in time of action.

THE DRILL CALLED ARMATURA

The new levies also should be taught by the masters at arms the system of drill called armatura, as it is still partly kept up among us. Experience even at this time convinces us that soldiers, perfect therein, are of the most service in engagements. And they afford certain proofs of the importance and effects of discipline in the difference we see between those properly trained in this branch of drill and the other troops. The old Romans were so conscious of its usefulness that they rewarded the masters at arms with a double allowance of provision. The soldiers who were backward in this drill were punished by having their allowance in barley. Nor did they receive it as usual, in wheat, until they had, in the presence of the prefect, tribunes, or other principal officers of the legion, showed sufficient proofs of their knowledge of every part of their study.

No state can either be happy or secure that is remiss and negligent in the discipline of its troops. For it is not profusion of riches or excess of luxury that can influence our enemies to court or respect us. This can only be effected by the terror of our arms. It is an observation of Cato that. misconduct in the common affairs of life may be retrieved, but that it is quite otherwise in war, where errors are fatal and without remedy, and are followed by immediate punishment. For the consequences of engaging an enemy, without skill or courage, is that part of the army is left on the field of battle, and those who remain receive such an impression from their defeat that they dare not afterwards look the enemy in the face.

THE USE OF MISSILE WEAPONS

Besides the aforementioned exercise of the recruits at the post, they were furnished with javelins of greater weight than common, which they were taught to throw at the same post. And the masters at arms were very careful to instruct them how to cast them with a proper aim and force. This practice strengthens the arm and makes the soldier a good marksman.

THE USE OF THE BOW

A third or fourth of the youngest and fittest soldiers should also be exercised at the post with bows and arrows made for that purpose only. The masters for this branch must be chosen with care and must apply themselves diligently to teach the men to hold the bow in a proper position, to bend it with strength, to keep the left hand steady. to draw the right with skill, to direct both the attention and the eye to the object, and to take their aim with equal certainty either on foot or on horseback. But this is not to be acquired without great application, nor to be retained without daily exercise and practice.

The utility of good archers in action is evidently demonstrated by Cato in his treatise on military discipline. To the institution of a body of troops of this sort Claudius owed his victory over an enemy who, till that time, had constantly been superior to him. Scipio Africanus, before his battle with the Numantines, who had made a Roman army ignominiously pass under the yoke, thought he could have no likelihood of success except by mingling a number of select archers with every century.

THE SLING

Recruits are to be taught the art of throwing stones both with the hand and sling. The inhabitants of the Balearic Islands are said to have been the inventors of slings, and to have managed them with surprising dexterity, owing to the manner of bringing up their children. The children were not allowed to have their food by their mothers till they had first struck it with their sling. Soldiers, notwithstanding their defensive armor, are often more annoyed by the round stones from the sling than by all the arrows of the enemy. Stones kill without mangling the body, and the contusion is mortal without loss of blood. It is universally known the ancients employed slingers in all their engagements. There is the greater reason for instructing all troops, without exception, in this exercise, as the sling cannot be reckoned any incumbrance, and often is of the greatest service, especially when they are obliged to engage in stony places, to defend a mountain or an eminence, or to repulse an enemy at the attack of a castle or city.

THE LOADED JAVELIN

The exercise of the loaded javelins, called martiobarbuli, must not be omitted. We formerly had two legions in lllyricum, consisting of six thousand men each, which from their extraordinary dexterity and skill in the use of these weapons were discingui.shed by the same appellation. They supported for a long time the weight of all the wars and distinguished themselves so remarkably that the Emperors Diocletian and Maximian on their accession honored them with the titles of Jovian and Herculean and preferred them before all the other legions. Every soldier carries five of these javelins in the hollow of his shield. And thus the legionary soldiers seem to supply the place of archers, for they wound both the men and horses of the enemy before they come within reach of the common missile weapons.

TO BE TAUGHT TO VAULT

The ancients strictly obliged both the veteran soldiers and recruits to a constant practice of vaulting. It has indeed reached our cimes, although little regard is paid to it at present. They had wooden horses for that purpose placed in winter under cover and in summer in the field. The young soldiers were taught to vault on them at first without arms, afterwards completely armed. And such was their attention to this exercise that they were accustomed to mount and dismount on either side indifferently, with their drawn swords or lances in their hands. By assiduous practice in the leisure of peace, their cavalry was brought to such perfection of discipline that they mounted their horses in an instant even amidst the confusion of sudden and unexpected alarms.

AND TO CARRY BURDENS

To accustom soldiers to carry burdens is also an essential part of discipline. Recruits in particular should be obliged frequently to carry a weight of not less than sixty pounds (exclusive of their arms), and to march with it in the ranks. This is because on difficult expeditions they often find themselves under the necessity of carrying their provisions as well as their arms. Nor will they find this troublesome when inured to it by custom, which makes everything easy. Our troops in ancient times were a proof of this, and Virgil has remarked it in the following lines:

The Roman soldiers, bred in war's alarms,

Bending with unjust loads and heavy arms,

Cheerful their toilsome marches undergo,

And pitch their sudden camp before the foe.

THE ARMS OF THE ANCIENTS

The manner of arming the troops comes next under consideration. But the method of the ancients no longer is followed. For though after the example of the Goths, the Alans and the Huns, we have made some improvements in the arms of the cavalry, yet it is plain the infantry are entirely defenseless. From the foundation of the city till the reign of the Emperor Gratian, the foot wore cuirasses and helmets. But negligence and sloth having by degrees introduced a total relaxation of discipline, the soldiers began to think their armor too heavy, as they seldom put it on. They first requested leave from the Emperor to lay aside the cuirass and afterwards the helmet. In consequence of this, our troops in their engagements with the Goths were often overwhelmed with their showers of arrows. Nor was the necessity of obliging the infantry to resume their cuirasses and helmets discovered, notwithstanding such repeated defeats, which brought on the destruction of so many great cities.

Troops, defenseless and exposed to all the weapons of the enemy, are more disposed to fly than fight. What can be expected from a foot-archer without cuirass or helmet, who cannot hold at once his bow and shield; or from the ensigns whose bodies are naked, and who cannot at the same time carry a shield and the colors? The foot soldier finds the weight of a cuirass and even of a helmet intolerable. This is because he is so seldom exercised and rarely puts them on.

But the case would be quite different, were they even heavier than they are, if by constant practice he had been accustomed to wear them. But it seems these very men, who cannot support the weight of the ancient armor, think nothing of exposing themselves without defense to wounds and death, or, which is worse, to the shame of being made prisoners, or of betraying their country by flight; and thus to avoid an inconsiderable share of exercise and fatigue, suffer themselves ignominiously to be cut in pieces. With what propriety could the ancients call the infantry a wall, but that in some measure they resembled it by the complete armor of the legionary soldiers who had shields, helmets, cuirasses, and greaves of iron on the right leg; and the archers who had gauntlets on the left arm. These were the defensive arms of the legionary soldiers. Those who fought in the first line of their respective legions were called principes, in the second hastati, and in third triarii.

The triarii, according to their method of discipline, rested in time of action on one knee, under cover of their shields, so that in this position they might be less exposed to the darts of the enemy than if they stood upright; and also, when there was a necessity for bringing them up, that they might be fresh, in full vigor and charge with the greater impetuosity. There have been many instances of their gaining a complete victory after the entire defeat of both the principes and hastati.

The ancients had likewise a body of light infantry, slingers, and ferentarii (the light troops), who were generally posted on the wings and began the engagement. The most active and best disciplined men were selected for this service; and as their number was not very great, they easily retired in case of a repulse through the intervals of the legion, without thus occasioning the least disorder in the line.

The Pamonian leather caps worn by our soldiers were formerly introduced with a different design. The ancients obliged the men to wear them at all times so that being constantly accustomed to have the head covered they might be less sensible of the weight of the helmet.

As to the missile weapons of the infantry, they were javelins headed with a triangular sharp iron, eleven inches or a foot long, and were called piles. When once fixed in the shield it was impossible to draw them out, and when thrown with force and skill, they penetrated the cuirass without difficulty. At present they are seldom used by us, but are the principal weapon of the barbarian heavy-armed foot. They are called bebrae, and every man carries two or three of them to battle.

It must be observed that when the soldiers engage with the javelin, the left foot should be advanced, for, by this attitude the force required to throw it is considerably increased. On the contrary, when they are close enough to use their piles and swords, the right foot should be advanced, so that the body may present less aim to the enemy, and the right arm be nearer and in a more advantageous position for striking. Hence it appears that it is as necessary to provide soldiers with defensive arms of every kind as to instruct them in the use of offensive ones. For it is certain a man will fight with greater courage and confidence when he finds himself properly armed for defense.

ENTRENCHED CAMPS

Recruits are to be instructed in the manner of entrenching camps, there being no part of discipline so necessary and useful as this. For in a camp, well chosen and entrenched, the troops both day and night lie secure within their works, even though in view of the enemy. It seems to resemble a fortified city which they can build for their safety wherever they please. But this valuable art is now entirely lost, for it is long since any of our camps have been fortified either with trenches or palisades. By this neglect our forces have been often surprised by day and night by the enemy's cavalry and suffered very severe losses. The importance of this custom appears not only from the danger to which troops are perpetually exposed who encamp without such precautions, but from the distressful situation of an army that, after receiving a check in the field, finds itself without retreat and consequently at the mercy of the enemy. A camp, especially in the neighborhood of an enemy, must be chosen with great care. Its situation should be strong by nature, and there should be plenty of wood, forage and water. If the army is to continue in it any considerable time, attention must be had to the salubrity of the place. The camp must not be commanded by any higher grounds from whence it might be insulted or annoyed by the enemy, nor must the location be liable to floods which would expose the army to great danger. The dimensions of the camps must be determined by the number of troops and quantity of baggage, that a large army may have room enough, and that a small one may not be obliged to extend itself beyond its proper ground. The form of the camps must be determined by the site of the country, in conformity to which they must be square, triangular or oval. The Praetorian gate should either front the east or the enemy. In a temporary camp it should face the route by which the army is to march. Within this gate the tents of the first centuries or cohorts are pitched, and the dragons* and other ensigns planted.

The Decumane gate is directly opposite to the Praetorian in the rear of the camp, and through this the soldiers are conducted to the place appointed for punishment or execution.

There are two methods of entrenching a camp. When the danger is not imminent, they carry a slight ditch round the whole circuit, only nine feet broad and seven deep. With the turf taken from this they make a kind of wall or breastwork three feet high on the inner side of the ditch. But where there is reason to be apprehensive of attempts of the enemy, the camp must be surrounded with a regular ditch twelve feet broad and nine feet deep perpendicular from the surface of the ground. A parapet is then raised on the side next the camp, of the height of four feet, with hurdles and fascines properly covered and secured by the earth taken out of the ditch. From these dimensions the interior height of the intrenchment will be found to be thirteen feet, and the breadth of the ditch twelve. On the top of the whole are planted strong palisades which the soldiers carry constantly with them for this purpose. A sufficient number of spades, pickaxes, wicker baskets and tools of all kinds are to be provided for these works.

There is no difficulty in carrying on the fortifications of a camp when no enemy is in sight. But if the enemy is near, all the cavalry and half the infantry are to be drawn up in order of battle to cover the rest of the troops at work on the entrenchments and be ready to receive the enemy if they offer to attack. The centuries are employed by turns on the work and are regularly called to the relief by a crier till the whole is completed. It is then inspected and measured by the centurions, who punish such as have been indolent or negligent. This is a very important point in the discipline of young soldiers, who when properly trained to it will be able in an emergency to fortify their camp with skill and expedition.

EVOLUTIONS

No part of drill is more essential in action than for soldiers to keep their ranks with the greatest exactness, without opening or closing too much. Troops too much crowded can never fight as they ought, and only embarrass one another. If their order is too open and loose, they give the enemy an opportunity of penetrating. Whenever this happens and they are attacked in the rear, universal disorder and confusion are inevitable. Recruits should therefore be constantly in the field, drawn up by the roll and formed at first into a single rank. They should learn to dress in a straight line and to keep an equal and just distance between man and man. They must then be ordered to double the rank, which they must perform very quickly, and instantly cover their file leaders. In the next place, they are to double again and form four deep. And then the triangle or, as it is commonly called, the wedge, a disposition found very serviceable in action. They must be taught to form the circle or orb; for well-disciplined troops, after being broken by the enemy, have thrown themselves into this position and have thereby prevented the total rout of the army. These evolutions, often practiced in the field of exercise, will be found easy in execution on actual service.

MONTHLY MARCHES

It was a constant custom among the old Romans, confirmed by the Ordinances of Augustus and Hadrian, to exercise both cavalry and infantry three times in a month by marches of a certain length. The foot were obliged to march completely armed the distance of ten miles from the camp and return, in the most exact order and with the military step which they changed and quickened on some part of the march. Their cavalry likewise, in troops and properly armed, performed the same marches and were exercised at the same time in their peculiar movement and evolutions; sometimes, as if pursuing the enemy, sometimes retreating and returning again with greater impetuosity to the charge. They made these marches not in plain and even ground only, but both cavalry and infantry were ordered into difficult and uneven places and to ascend or descend mountains, to prepare them for all kinds of accidents and familiarize them with the different maneuvers that the various situations of a country may require.

CONCLUSION

These military maxims and instructions, invincible Emperor, as a proof of my devotion and zeal for your service, I have carefully collected from the works of all the ancient authors on the subject. My design herein is to point out the certain method of forming good and serviceable armies, which can only be accomplished by an exact imitation of the ancients in their care in the choice and discipline of their levies. Men are not degenerated in point of courage, nor are the countries that produced the Lacedaemonians, the Athenians, the Marsians, the Samnites, the Peligni and even the Romans themselves, yet exhausted. Did not the Epirots acquire in former times a great reputation in war? Did not the Macedonians and Thessalians, after conquering the Persians, penetrate even into India? And it is well known that the warlike dispositions of the Dacians, Moesians and Thracians gave rise to the fable that Mars was born among them.

To pretend to enumerate the different nations so formidable of old, all which now are subject to the Romans, would be tedious. But the security established by long peace has altered their dispositions, drawn them off from military to civil pursuits and infused into them a love of idleness and ease. Hence a relaxation of military discipline insensibly ensued, then a neglect of it, and it sunk at last into entire oblivion. Now will it appear surprising that this alteration should have happened in latter times, if we consider that the peace, which lasted about twenty years or somewhat more after the first Punic war, enervated the Romans, before everywhere victorious, by idleness and neglect of discipline to such a degree, that in the second Punic war they were not able to keep the field against Hannibal. At last, after the defeat of many consuls and the loss of many officers and armies, they were convinced that the revival of discipline was the only road to victory and thereby recovered their superiority. The necessity, therefore, of discipline cannot be too often inculcated, as well as the strict attention requisite in the choice and training of new levies. It is also certain that it is a much less expense to a State to train its own subjects to arms than to take foreigners into its pay.

* This mark was imprinted on the hands of the soldiers, either with a hot iron, or in some other manner. It was indelible.

* The dragon was the particular ensign of each cohort.

To the Emperor Valentinian

Such a continued series of victories and triumphs proved incontestably Your Majesty's full and perfect knowledge of the military discipline of the ancients. Success in any profession is the most certain mark of skill in it. By a greatness of mind. above human comprehension Your Majesty condescends to seek instruction from the ancients, notwithstanding your own recent exploits surpass antiquity itself. On receiving Your Majesty's orders to continue this abridgement, not so much for your instruction as convenience, I knew not how to reconcile my devotion to Your commands with the respect due to Your Majesty. Would it not be the greatest height of presumption to pretend to mention the art of war to the Lord and Master of the world and the Conqueror of all the barbarous nations, unless it were to describe his own actions? But disobedience to the will of so great a Prince would be both highly criminal and dangerous. My obedience, therefore, made me presumptuous, from the apprehensions of appearing more so by a contrary conduct. And in this I was not a little encouraged by the late instance of Your Majesty's indulgence. My treatise on the choice and discipline of new levies met with a favorable reception from Your Majesty, and since a work succeeded so well, composed of my own accord, I can have no fears for one undertaken by your own express commands.

Book II: The Organization of the Legion

THE MILITARY ESTABLISHMENT

The military establishment consists of three parts, the cavalry, infantry and marine. The wings of cavalry were so called from their similitude to wings in their extension on both sides of the main body for its protection. They are now called vexillations from the kind of standards peculiar to them. The legionary horse are bodies particularly annexed to each legion, and of a different kind; and on their model were organized the cavalry called Ocreati, from the light boots they wear. The fleet consists of two divisions, the one of men of war called Liburnae, and the other of armed sloops. The cavalry are designed for plains. Fleets are employed for the protection of seas and rivers. The infantry are proper for the defense of eminences, for the garrisons of cities and are equally serviceable in plain and in uneven ground. The latter, therefore, from their facility of acting everywhere, are certainly the most useful and necessary troops to a state exclusively of the consideration of their being maintained at a less expense. The infantry are divided into two corps, the legions and auxiliaries, the latter of which are furnished by allies or confederates. The peculiar strength of the Romans always consisted in the excellent organization of their legions. They were so denominated ab eligendo, from the care and exactness used in the choice of the soldiers. The number of legionary troops in an army is generally much more considerable than that of the auxiliaries.

DIFFERENCE BETWEEN THE LEGIONS AND AUXILIARIES

The Macedonians, the Greeks and the Dardanians formed their troops into phalanxes of eight thousand men each. The Gauls, Celtiberians and many other barbarous nations divided their armies into bodies of six thousand each. The Romans have their legions usually six thousand strong, sometImes more.

We shall now explain the difference between the legions and the auxiliaries. The latter are hired corps of foreigners assembled from different parts of the Empire, made up of different numbers, without knowledge of one another or any tie of affection. Each nation has its own peculiar discipline, customs and manner of fighting. Little can be expected from forces so dissimilar in every respect, since it is one of the most essential points in military undertakings that the whole army should be put in motion and governed by one and the same order. But it is almost impossible for men to act in concert under such varying and unsettled circumstances. They are, however, when properly trained and disciplined, of material service and are always joined as light troops with the legions in the line. And though the legions do not place their principal dependence on them, yet they look on them as a very considerable addition to their strength.

But the complete Roman legion, in its own peculiar cohorts, contains within itself the heavy-armed foot, that is: the principes, hastati, triarii, and antefignani, the lightarmed foot, consisting of the ferentarii, archers, slingers, and balistarii, together with the legionary cavalry incorporated with it. These bodies, all actuated with the same spirit, are united inseparably in their various dispositions for forming, encamping and fighting. Thus the legion is compact and perfect in all its parts and, without any foreign assistance, has always been superior to any force that could be brought against it. The Roman greatness is a proof of the excellence of their legions, for with them they always defeated whatever numbers of the enemy they thought fit, or their circumstances gave them an opportunIty to engage.

CAUSES OF DECAY OF THE LEGION

The name of the legion remains indeed to this day in our armies, but its strength and substance are gone, since by the neglect of our predecessors, honors and preferments, which were formerly the recompenses of merit and long services, were to be attained only by interest and favor. Care is no longer taken to replace the soldiers, who after serving their full time, have received their discharges. The vacancies continually happening by sickness, discharges, desertion and various other casualties, if not supplied every year or even every month, must in time disable the most numerous army. Another cause of the weakness of our legions is that in them the soldiers find the duty hard, the arms heavy, the rewards distant and the discipline severe. To avoid these inconveniences, the young men enlist in the auxiliaries, where the service is less laborious and they have reason to expect more speedy recompenses.

Cato the Elder, who was often Consul and always victorious at the head of the armies, believed he should do his country more essential service by writing on military affairs, than by all his exploits in the field. For the consequences of brave actions are only temporary, while whatever is committed to writing for public good is of lasting benefit. Several others have followed his example, particularly Frontinus, whose elaborate works on this subject were so well received by the Emperor Trajan. These are the authors whose maxims and institutions I have undertaken to abridge in the most faithful and conclse manner.

The expense of keeping up good or bad troops is the same; but it depends wholly on You, most August Emperor, to recover the excellent discipline of the ancients and to correct the abuses of later times. This is a reformation the advantages of which will be equally felt by ourselves and our posterity.

THE ORGANIZATION OF THE LEGION

All our writers agree that never more than two legions, besides auxiliaries, were sent under the command of each consul against the most numerous armies of the enemies. Such was the dependence on their discipline and resolution that this number was thought sufficient for any war they were engaged in. I shall therefore explain the organization of the ancient legion according to the military constitution. But if the description appear obscure or imperfect, it is not to be imputed to me, but to the difficulty of the subject itself, which is therefore to be examined with the greater attention. A prince, skilled himself in military affairs, has it in his power to make himself invincible by keeping up whatever number of well disciplined forces he thinks proper.

The recruits having thus been carefully chosen with proper attention to their persons and dispositions, and having been daily exercised for the space of four months at least, the legion is formed by the command and under the auspices of the Emperor. The military mark, which is indelible, is first imprinted on the hands of the new levies, and as their names are inserted in the roll of the legions they take the usual oath, called the military oath. They swear by God, by Christ and by the Holy Ghost; and by the Majesty of the Emperor who, after God, should be the chief object of the love and veneration of mankind. For when he has once received the title of August, his subjects are bound to pay him the most sincere devotion and homage, as the representative of God on earth. And every man, whether in a private or military station, serves God in serving him faithfully who reigns by His authority. The soldiers, therefore, swear they will obey the Emperor willingly and implicitly in all his commands, that they will never desert and will always be ready to sacrifice their lives for the Roman Empire.

The legion should consist of ten cohorts, the first of which exceeds the others both in number and quality of its soldiers, who are selected to serve in it as men of some family and education. This cohort has the care of the eagle, the chief ensign in the Roman armies and the standard of the whole legion, as well as of the images of the emperors which are always considered as sacred. It consists of eleven hundred and five foot and one hundred and thirty-two horse cuirassiers, and is distinguished by the name of the Millarian Cohort. It is the head of the legion and is always first formed on the right of the first line when the legion draws up in order of battle.

The second cohort contains five hundred and fifty-five foot and sixty-six horse, and is called the Quingentarian Cohort. The third is composed of five hundred and fiftyfive foot and sixty-six horse, generally chosen men, on account of its situation in the center of the first line. The fourth consists of the same number of five hundred and fifty-five foot and sixty-six horse. The fifth has likewise five hundred and fifty-five foot and sixty-six horse, which should be some of the best men, being posted on the left flank as the first cohort is on the right. These five cohorts compose the first line.

The sixth includes five hundred and fifty-five foot and sixty-six horse, which should be the flower of the young soldiers as it draws up in the rear of the eagle and the images of the emperors, and on the right of the second line. The seventh contains five hundred and fifty-five foot and sixty-six horse. The eighth is composed of five hundred and fifty-five foot and sixty-six horse, all selected troops, as it occupies the center of the second line. The ninth has five hundred and fifty-five foot and sixty-six horse. The tenth consists of the same number of five hundred and fifty-five foot and sixty-six horse and requires good men, as it closes the left flank of the second line. These ten cohorts form the complete legions, consisting in the whole of six thousand one hundred foot and seven hundred and twenty-six horses. A legion should never be composed of a less number of men, but it is sometimes stronger by the addition of other Millarian Cohorts.

THE OFFICERS OF THE LEGION

Having shown the ancient establishment of the legion, we shall now explain the names of the principal soldiers or, to use the proper term, the officers, and their ranks according to the present rolls of the legions. The first tribune is appointed by the express commission and choice of the Emperor. The second tribune rises to that rank by length of service. The tribunes are so called from their command over the soldiers, who were at first levied by Romulus out of the different tribes. The officers who in action commanded the orders or divisions are called Ordinarii. The Augustales were added by Augustus to the Ordinarii; and the Flaviales were appointed by Flavius Vespasian to double the number of the Augustales. The eagle-bearers and the image-bearers are those who carry the eagles and images of the Emperors. The Optiones are subaltern officers, so denominated from their being selected by the option of their superior officers, to do their duty as their substitutes or lieutenants in case of sickness or other accident. The ensign-bearers carry the ensigns and are called Draconarii. The Tesserarii deliver the parole and the orders of the general to the different messes of the soldiers. The Campignei or Antefignani are those whose duty it is to keep the proper exercises and discipline among the troops. The Metatores are ordered before the army to fix on the ground for its encampments. The Beneficiarii are so named from their owing their promotion to the benefit or interest of the Tribunes. The Librarii keep the legionary accounts. The Tubicines, Cornicines, and Buccinatores derive their appellations from blowing the trumpet, cornet, and buccina. Those who, expert in their exercises, receive a double allowance of provisions, are called Armaturae Duplares, and those who have but a single portion, Simplares. The Mensores mark out the ground by measure for the tents in an encampment, and assign the troops their respective quarters in garrison. The Torquati, so denominated from the gold collars given them in reward for their bravery, had besides this honor different allowances. Those who received double were called Torquati Duplares, and those who had only single, Simplares. There were, for the same reason, Candidatii Duplares, and Candidatii Simplares. These are the principal soldiers or officers distinguished by their rank and privileges thereto annexed. The rest are called Munifices, or working soldiers, from their being obliged to every kind of military work without exception. Formerly it was the rule that the first Princeps of the legion should be promoted regularly to the rank of Centurion of the Primiple. He not only was entrusted with the eagle but commanded four centuries, that is, four hundred men in the first line. As head of the legion he had appointments of great honor and profit. The first Hastatus had the command of two centuries or two hundred men in the second line, and is now called Ducenarius. The Princeps of the first cohort commanded a century and a half, that is, one hundred and fifty men, and kept in a great measure the general detail of the legion. The second Hastatus had likewise a century and a half, or one hundred and fifty men. The first Triarius had the command of one hundred men. Thus the ten centuries of the first cohort were commanded by five Ordinarii, who by the ancient establishment enjoyed great honors and emoluments that were annexed to this rank in order to inspire the soldiers of the legions with emulation to attain such ample and considerable rewards. They had also Centurions appointed to each century, now called Centenarii and Decani, who commanded ten men, now called heads of messes. The second cohort had five Centurions; and all the rest to the tenth inclusively the same number. In the whole legion there were fiftyfive.

Lieutenants of consular dignity were formerly sent to command in the armies under the general, and their authority extended over both the legions and auxiliaries in peace and war. Instead of these officers, persons of high rank are now substituted with the title of Masters of the Forces. They are not limited to the command of two legions only, but have often a greater number. But the peculiar officer of the legion was the Praefect, who was always a count of the first order. On him the chief command devolved in the absence of the lieutenant. The Tribunes, Centurions, and all the soldiers in general were under his orders: He gave out the parole and order for the march and for the guards. And if a soldier committed a crime, by his authority the Tribune adjudged him to punishment. He had charge of the arms, horses, clothing and provisions. It was also his duty to keep both the legionary horse and foot in daily exercise and to maintain the strictest discipline. He ought to be a careful and diligent officer, as the sole charge of forming the legion to regularity and obedience depended on him and the excellence of the soldiers redounded entirely to his own honor and credit.

The Praefect of the camp, though inferior in rank to the former, had a post of no small importance. The position of the camp, the direction of the entrenchments, the inspection of the tents or huts of the soldiers and the baggage were comprehended in his province. His authority extended over the sick, and the physicians who had the care of them; and he regulated the expenses relative thereto. He had the charge of providing carriages, bathorses and the proper tools for sawing and cutting wood, digging trenches, raising parapets, sinking wells and bringing water into the camp. He likewise had the care of furnishing the troops with wood and straw, as well as the rams, onagri, balistae and all the other engines of war under his direction. This post was always conferred on an officer of great skill, experience and long service, and who consequently was capable of instructing others in those branches of the profession in which he had distinguished himself.

THE PRAEFECT OF THE WORKMEN

The legion had a train of joiners, masons, carpenters, smiths, painters, and workmen of every kind for the construction of barracks in the winter-camps and for making or repairing the wooden towers, arms, carriages and the various sorts of machines and engines for the attack or defense of places. They had also traveling workshops in which they made shields, cuirasses, helmets, bows, arrows, javelins and offensive and defensive arms of all kinds. The ancients made it their chief care to have every thing for the service of the army within the camp. They even had a body of miners who, by working under ground and piercing the foundations of walls, according to the practice of the Beffi, penetrated into the body of a place. All these were under the direction of the officer called the praefect of the workmen.

THE TRIBUNE OF THE SOLDIERS

We have observed that the legions had ten cohorts, the first of which, called the Millarian Cohort, was composed of men selected on account of their circumstances, birth, education, person and bravery. The tribune who commanded them was likewise distinguished for his skill in his exercises, for the advantages of his person and the integrity of his manners. The other cohorts were commanded, according to the Emperor's pleasure, either by tribunes or other officers commissioned for that purpose. In former times the discipline was so strict that the tribunes or officers abovementioned not only caused the troops under their command to be exercised daily in their presence, but were themselves so perfect in their military exercises as to set them the example. Nothing does so much honor to the abilities or application of the tribune as the appearance and discipline of the soldiers, when their apparel is neat and clean, their arms bright and in good order and when they perform their exercises and evolutions with dexterity.

CENTURIES AND ENSIGNS OF THE FOOT

The chief ensign of the whole legion is the eagle and is carried by the eagle-bearer. Each cohort has also its own peculiar ensign, the Dragon, carried by the Draconarius. The ancients, knowing the ranks were easily disordered in the confusion of action, divided the cohorts into centuries and gave each century an ensign inscribed with the number both of the cohort and century so that the men keeping it in sight might be prevented from separating from their comrades in the greatest tumults. Besides the centurions, now called centenarii, were distinguished by different crests on their helmets, to be more easily known by the soldiers of their respective centuries. These precautions prevented any mistake, as every century was guided not only by its own ensign but likewise by the peculiar form of the helmet of its commanding officers. The centuries were also subdivided into messes of ten men each who lay in the same tent and were under orders and inspection of a Decanus or head of the mess. These messes were also called Maniples from their constant custom of fighting together in the same company or division.

LEGIONARY TROOPS OF HORSE

As the divisions of the infantry are called centuries, so those of the cavalry are called troops. A troop consists of thirty-two men and is commanded by a Decurion. Every century has its ensign and every troop its Standard. The centurion in the infantry is chosen for his size, strength and deXterity in throwing his missile weapons and for his skill in the use of his sword and shield; in short for his expertness in all the exercises. He is to be vigilant, temperate, accive and readier to execute the orders he receives than to talk; Strict in exercising and keeping up proper discipline among his soldiers, in obliging them to appear clean and well-dressed and to have their arms constantly rubbed and bright. In like manner the Decurion is to be preferred to the command of a troop for his activity and address in mounting his horse completely armed; for his skill in riding and in the use of the lance and bow; for his attencion in forming his men to all the evolutions of the cavaIry; and for his care in obliging them to keep their cuirasses, lances and helmets always bright and in good order. The splendor of the arms has no inconsiderable effect in striking terror into an enemy. Can that man be reckoned a good soldier who through negligence suffers his arms to be spoiled by dirt and rust? In short, it is the duty of the Decurion to be attentive to whatever concerns the health or discipline of the men or horses in his troop.

DRAWING UP A LEGION IN ORDER OF BATTLE

We shall exemplify the manner of drawing up an army in order of battle in the instance of one legion, which may serve for any number. The cavalry are posted on the wings. The infantry begin to form on a line with the :first cohort on the right. The second cohort draws up on the left of the first; the third occupies the center; the fourth is posted next; and the fifth closes the left flank. The ordinarii, the other officers and the soldiers of the first line, ranged before and round the ensigns, were called the principes. They were all heavy armed troops and had helmets, cuirasses, greaves, and shields. Their offensive weapons were large swords, called spathae, and smaller ones called semispathae together with five loaded javelins in the concavity of the shield, which they threw at the first charge. They had likewise two other javelins, the largest of which was composed of a staff five feet and a half long and a triangular head of iron nine inches long. This was formerly called the pilum, but now it is known by the name of spiculum. The soldiers were particularly exercised in the use of this weapon, because when thrown with force and skill it often penetrated the shields of the foot and the cuirasses of the horse. The other javelin was of smaller size; its triangular point was only five inches long and the staff three feet and one half. It was anciently called verriculum but now verutum.

The first line, as I said before, was composed of the principes; the hastati formed the second and were armed in the same manner. In the second line the sixth cohort was posted on the right flank, with the seventh on its left; the eighth drew up in the center; the ninth was the next; and the tenth always closed the left flank. In the rear of these two lines were the ferentarii, light infantry and the troops armed with shields, loaded javelins, swords and common missile weapons, much in the same manner as our modern soldiers. This was also the post of the archers who had helmets, cuirasses, swords, bows and arrows; of the slingers who threw stones with the common sling or with the fustibalus; and of the tragularii who annoyed the enemy with arrows from the manubalistae or arcubalistae.

In the rear of all the lines, the triarii, completely armed, were drawn up. They had shields, cuirasses, helmets, greaves, swords, daggers, loaded javelins, and two of the common missile weapons. They rested during the acnon on one knee, so that if the first lines were obliged to give way, they might be fresh when brought up to the charge, and thereby retrieve what was lost and recover the victory. All the ensigns though, of the infantry, wore cuirasses of a smaller sort and covered their helmets with the shaggy skins of beasts to make themselves appear more terrible to the enemy. But the centurions had complete cuirasses, shields, and helmets of iron, the crest of which, placed transversely thereon, were ornamented with silver that they might be more easily distinguished by their respective soldiers.

The following disposition deserves the greatest attention. In the beginning of an engagement, the first and second lines remained immovable on their ground, and the trairii in their usual positions. The light-armed

troops, composed as above mentioned, advanced in the front of the line, and attacked the enemy. If they could make them give way, they pursued them; but if they were repulsed by superior bravery or numbers, they retired behind their own heavy armed infantry, which appeared like a wall of iron and renewed the action, at first with their missile weapons, then sword in hand. If they broke the enemy they never pursued them, least they should break their ranks or throw the line into confusion, and lest the enemy, taking advantage of their disorder, should return to the attack and destroy them without difficulty. The pursuit therefore was entirely left to the light-armed troops and the cavalry. By these precautions and dispositions the legion was victorious without danger, or if the contrary happened, was preserved without any considerable loss, for as it is not calculated for pursuit, it is likewise not easily thrown into disorder.

NAMES OF SOLDIERS INSCRIBED ON THEIR SHIELDS

Lest the soldiers in the confusion of battle should be separated from their comrades, every cohort had its shields painted in a manner peculiar to itself. The name of each soldier was also written on his shield, together with the number of the cohort and century to which he belonged. From this description we may compare the legion, when in proper order, to a well fortified city as containing within itself every thing requisite in war, wherever it moved. It was secure from any sudden attempt or surprise of an enemy by its expeditious method of entrenching its camp even in the open plains and it was always provided with troops and arms of every kind. To be victorious, therefore, over our enemies in the field, we must unanimously supplicate heaven to dispose the Emperor to reform the abuses in raising our levies and to recruit our legions after the method of the ancients. The same care in choosing and instructing our young soldiers in all military exercises and drills will soon make them equal to the old Roman troops who subdued the whole world. Nor let this alteration and loss of ancient discipline in any way affect Your Majesty, since it is a happiness reserved for You alone both to restore the ancient ordinances and establish new ones for the public welfare. Every work before the attempt carries in it an appearance of difficulty; but in this case, if the levies are made by careful and experienced officers, an army may be raised, disciplined and rendered fit for service in a very short time; for the necessary expenses once provided, diligence soon effects whatever it undertakes.

RECORDS AND ACCOUNTS

Several posts in the legion requiring men of some education, the superintendents of the levies should select some recruits for their skill in writing and accounts, besides the qualification to be attended to in general, such as size, strength and proper disposition for the service. For the whole detail of the legion, including the lists of the soldiers exempted from duty on private accounts, the rosters for their tour of military duties and their pay lists, is daily entered in the legionary books and kept we may almost say, with greater exactness than the regulations of provisions or other civil matters in the registers of the police. The daily guards in time of peace, the advanced guards and outposts in time of war, which are mounted regularly by the centuries and messes in their turns, are likewise punctually kept in rolls for that purpose, with the name of each soldier whose tour is past, that no one may have injustice done him or be excused from his duty by favor.

They are also exact in entering the time and limitation of furloughs, which formerly were never granted without difficulty and only on real and urgent business. They then never suffered the soldiers to attend on any private person or to concern themselves in private occupations, thinking it absurd and improper that the Emperor's soldiers, clothed and subsisted at the public expense, should follow any other profession. Some soldiers, however, were allowed for the service of the praefects, tribunes and even of the other officers, our of the number of the accensi or such as were raised after the legion was complete. These latter are now called supernumeraries. The regular troops were obliged to carry their wood, hay, water and straw into the camp themselves. From such kind of services they were called munifices.

SOLDIER'S DEPOSITS

The institution of the ancients which obliged the soldiers to deposit half of every donative they received at the colors was wise and judicious; the intent was to preserve it for their use so that they might not squander it in extravagance or idle expense. For most men, particularly the poorer sort, soon spend whatever they can get. A reserve of this kind therefore is evidently of the greatest service to the soldiers themselves; since they are maintained at the public expense, their military stock by this method is continually increasing. The soldier who knows all his fortune is deposited at his colors, entertains no thoughts of desertion, conceives a greater affection for them and fights with greater intrepidity in their defense. He is also prompted thereto by interest, the most prevailing consideration among men. This money was contained in ten bags, one for each cohort. There was an eleventh bag also for a small contribution from the whole legion, as a common fund to defray the expense of burial of any of their deceased comrades. These collections were kept in baskets in the custody of the ensigns, chosen for their integrity and capacity, and answerable for the trust and obliged to account with every man for his own proportion.

PROMOTION IN THE LEGION

Heaven certainly inspired the Romans with the organization of the legion, so superior does it seem to human invention. Such is the arrangement and disposition of the ten cohorts that compose it, as to appear one perfect body and form one complete whole. A soldier, as he advances in rank, proceeds as it were by rotation through the different degrees of the several cohorts in such a manner that one who is promoted passes from the first cohort to the tenth, and returns again regularly through all the others with a continual increase of rank and pay to the first. Thus the centurion of the primiple, after having commanded in the different ranks of every cohort, attains that great dignity in the first with infinite advantages from the whole legion. The chief praefect of the Praetorian Guards rises by the same method of rotation to that lucrative and honorable rank. Thus the legionary horse contract an affection for the foot of their own cohorts, notwithstanding the natural antipathy existing between the two corps. And this connection establishes a reciprocal attachment and union between all the cohorts and the cavalry and infantry of the legion.

LEGIONARY MUSIC

The music of the legion consists of trumpets, cornets and buccinae. The trumpet sounds the charge and the retreat. The cornets are used only to regulate the motions of the colors; the trumpets serve when the soldiers are ordered out to any work without the colors; but in time of action, the trumpets and cornets sound together. The classicum, which is a particular sound of the buccina or horn, is appropriated to the commander-in-chief and is used in the presence of the general, or at the execution of a soldier, as a mark of its being done by his authority. The ordinary guards and outposts are always mounted and relieved by the sound of trumpet, which also directs the motions of the soldiers on working parties and on field days. The cornets sound whenever the colors are to be struck or planted. These rules must be punctually observed in all exercises and reviews so that the soldiers may be ready to obey them in action without hesitation according to the general's orders either to charge or halt, to pursue the enemy or to retire. F or reason will convince us that what is necessary to be performed in the heat of action should constantly be practiced in the leisure of peace.

THE DRILLING OF THE TROOPS

The organization of the legion being thus explained, let us return to the drills. The younger soldiers and recruits went through their drills of every kind every morning and afternoon and the veterans and most expert regularly once a day. Length of service or age alone will never form a military man, for after serving many years an undisciplined soldier is still a novice in his profession. Not only those under the masters at arms, but all the soldiers in general, were formerly trained incessantly in those drills which now are only exhibited as shows in the circus for particular solemnities. By practice only can be acquired agility of body and the skill requisite to engage an enemy with advantage, especially in close fight. But the most essential point of all is to teach soldiers to keep their ranks and never abandon their colors in the most difficult evolutions. Men thus trained are never at a loss amidst the greatest confusion of numbers.

The recruits likewise are to be exercised with wooden swords at the post, to be taught to attack this imaginary antagonist on all sides and to aim at the sides, feet or head, both with the point and edge of the sword. They must be instructed how to spring forward to give the blow, to rise with a bound above the shield and then to sink down and shelter themselves under cover of it, and how to advance and retire. They must also throw their javelins at the post from a considerable distance in order to acquire a good aim and strengthen the arm.

The archers and slingers set up bundles of twigs or straw for marks, and generally strike them with arrows and with stones from the fustiablus at the distance of six hundred feet. They acquired coolness and exactness in acnon from familiar custom and exercise in the field. The slingers should be taught to whirl the sling but once about the head before they cast the stone. Formerlyall soldiers were trained to the praccice of throwing stones of a pound weight with the hand, as this was thought a readier method since it did not require a sling. The use of the common missile weapons and loaded javelins was another part of the drill strictly attended to.

To continue this drill without interruption during the winter, they erected for the cavalry porticos or riding halls covered with tiles or shingles, and if they were not to be procured, with reeds, rushes or thatch. Large open halls were likewise constructed in the same manner for the use of the infantry. By these means the troops were provided with places of drill sheltered from bad weather. But even in winter, if it did not rain or snow, they were obliged to perform their drills in the field, lest an intermission of discipline should affect both the courage and constitution of the soldier. In short, both legionary and auxiliary troops should continually be drilled in cutting wood, carrying burdens, passing ditches, swimming in the sea or in rivers, marching in the full step and even running with their arms and baggage, so that, inured to labor in peace, they may find no difficulty in war. For, as the well trained soldier is eager for action, so does the untaught fear it. In war discipline is superior to strength; but if that discipline is neglected, there is no longer any difference between the soldier and the peasant. The old maxim is certain that the very essence of an art consists in constant practice.

MACHINES AND TOOLS OF THE LEGION

The legion owes its success to its arms and machines, as well as to the number and bravery of its soldiers. In the first place every century has a balista mounted on a carriage drawn by mules and served by a mess, that is by ten men from the century to which it belongs. The larger these engines are, the greater distance they carry and with the greater force. They are used not only to defend the entrenchments of camps, but are also placed in the field in the rear of the heavy armed infantry. And such is the violence with which they throw the darts that neither the cuirasses of the horse nor shields of the foot can resist them. The number of these engines in a legion is fiftyfive. Besides these are ten onagri, one for each cohort; they are drawn ready armed on carriages by oxen; in case of an attack, they defend the works of the camp by throwing stones as the balistae do darts.

The legion carries with it a number of small boats, each hollowed out of a single piece of timber, with long cables and sometimes iron chains to fasten them together. These boats, joined and covered with planks, serve as bridges over unfordable rivers, on which both cavalry and infantry pass without danger. The legion is provided with iron hooks, called wolves, and iron scythes fixed to the ends of long poles; and with forks, spades, shovels, pickaxes, wheelbarrows and baskets for digging and transporting earth; together with hatchets, axes and saws for cutting wood. Besides which, a train of workmen attend on it furnished with all instruments necessary for the construction of tortoises, musculi, rams, vines, moving towers and other machines for the attack of places. As the enumeration of all the particulars of this sort would be too tedious, I shall only observe that the legion should carry with it wherever it moves, whatever is necessary for every kind of service so that the encampments may have all the strength and conveniences of a fortified city.

To the Emperor Valentinian

The Athenians and Lacedaemonians were masters of Greece before the Macedonians, as history informs us. The Athenians excelled not only in war but in other arts and sciences. The Lacedaemonians made war their chief study. They are affirmed to be the first who reasoned on the events of battles and committed their observations thereon to writing with such success as to reduce the military art, before considered as totally dependent on courage or fortune, to certain rules and fixed principles. As a consequence they established schools of tactics for the instruction of youth in all the maneuvers of war. How worthy of admiration are these people for particularly applying themselves to the study of an art, without which no other art can possibly exist. The Romans followed their example, and both practiced their institutions in their armies and preserved them in their writings. These are the maxims and instructions dispersed through the works of different authors, which Your Majesty has ordered me to abridge, since the perusal of the whole would be too tedious, and the authority of only a part unsatisfactory. The effect of the Lacedaemonian skill in dispositions for general actions appears evidently in the single instance of Xantippus, who assisted the Carthaginians after the repeated ruin of their armies. And merely superior skill and conduct defeated Attilius Regulus at the head of a Roman army, till that time always victorious. Xantippus took him prisoner and thus terminated the war by a single action. Hannibal, also, before he set out on his expedition into Italy, chose a Lacedaemonian for his counsellor in military operations; and by his advice, though inferior to the Romans both in number and strength, overthrew so many consuls and such mighty legions. He, therefore, who desires peace, should prepare for war. He who aspires to victory, should spare no pains to form his soldiers. And he who hopes for success, should fight on principle, not chance. No one dares to offend or insult a power of known superiority in action.

Book III: Dispositions for Action

THE NUMBER WHICH SHOULD COMPOSE AN ARMY

The first book treats of the choice and exercises of new levies; the second explains the establishment of the legion and the method of discipline; and the third contains the dispositions for action. By this methodical progression, the following instructions on general actions and means of victory will be better understood and of greater use. By an army is meant a number of troops, legions and auxiliaries, cavalry and infantry, assembled to make war. This number is limited by judges of the profession. The defeats of Xerxes, Darius, Mithridates and other monarchs who brought innumerable multitudes into the field, plainly show that the destruction of such prodigious armies is owing more to their own numbers than to the bravery of their enemies. An army too numerous is subject to many dangers and inconveniences. Its bulk makes it slow and unwieldy in its motions; and as it is obliged to march in columns of great length, it is exposed to the risk of being continually harassed and insulted by inconsiderable parties of the enemy. The incumbrance of the baggage is often an occasion of its being surprised in its passage through difficult places or over rivers. The difficulty of providing forage for such numbers of horses and other beasts of burden is very great. Besides, scarcity of provisions, which is to be carefully guarded against in all expeditions, soon ruins such large armies where the consumption is so prodigious, that notwithstanding the greatest care in filling the magazines they must begin to fail in a short time. And sometimes they unavoidably will be distressed for want of water. But, if unfortunately this immense army should be defeated, the numbers lost must necessarily be very great, and the remainder, who save themselves by flight, too much dispirited to be brought again to action.

The ancients, taught by experience, preferred discipline to numbers. In wars of lesser importance they thought one legion with auxiliaries, that is, ten thousand foot and two thousand horse, sufficient. And they often gave the command to a praeter as to a general of the second rank. When the preparations of the enemy were formidable, they sent a general of consular dignity with twenty thousand foot and four thousand horse. In our times this command was given to a count of the first order. But when there happened any dangerous insurrection supported by infinite multitudes of fierce and barbarous nations, on such emergencies they took the field with two armies under two consuls, who were charged, both singly and jointly, to take care to preserve the Republic from danger. In short, by this management, the Romans, almost continually engaged in war with different nations in different parts of the world, found themselves able to oppose them in every quarter. The excellence of their discipline made their small armies sufficient to encounter all their enemies with success. But it was an invariable rule in their armies that the number of allies or auxiliaries should never exceed that of the Roman citizens.

MEANS OF PRESERVING IT IN HEALTH

The next article is of the greatest importance: the means of preserving the health of the troops. This depends on the choice of situation and water, on the season of the year, medicine, and exercise. As to the situation, the army should never continue in the neighborhood of unwholesome marshes any length of time, or on dry plains or eminences without some sort of shade or shelter. In the summer, the troops should never encamp without tents. And their marches, in that season of the year when the heat is excessive, should begin by break of day so that they may arrive at the place of destination in good time. Otherwise they will contract diseases from the heat of the weather and the fatigue of the march. In severe winter they should never march in the night in frost and snow, or be exposed to want of wood or clothes. A soldier, starved with cold, can neither be healthy nor fit for service. The water must be wholesome and not marshy. Bad water is a kind of poison and the cause of epidemic distempers.

It is the duty of the officers of the legion, of the tribunes, and even of the commander-in-chief himself, to take care that the sick soldiers are supplied with proper diet and diligently attended by the physicians. For little can be expected from men who have both the enemy and diseases to struggle with. However, the best judges of the service have always been of the opinion that daily practice of the military exercises is much more efficacious towards the health of an army than all the art of medicine. For this reason they exercised their infantry without intermission. If it rained or snowed, they performed under cover; and il1 fine weather, in the field. They also were assiduous in exercising their cavalry, not only in plains, but also on uneven ground, broken and cut with ditches. The horses as well as the men were thus trained, both on the above mentioned account and to prepare them for action. Hence we may perceive the importance and necessity of a strict observance of the military exercises in an army, since health in the camp and victory in the field depend on them. If a numerous army continues long in one place in the summer or in the autumn, the waters become corrupt and the air infected. Malignant and fatal distempers proceed from this and can be avoided only by frequent changes of encampments.

CARE TO PROVIDE FORAGE AND PROVISIONS

Famine makes greater havoc in an army than the enemy, and is more terrible than the sword. Time and opportunity may help to retrieve other misfortunes, but where forage and provisions have not been carefully provided, the evil is without remedy. The main and principal point in war is to secure plenty of provisions and to destroy tIle enemy by famine. An exact calculation must therefore be made before the commencement of the war as to the number of troops and the expenses incident thereto, so that the provinces may in plenty of time furnish the forage, corn, and all other kinds of provisions demanded of them to be transported. They must be in more than sufficient quantity, and gathered into the strongest and most convenient cities before the opening of the campaign. If the provinces cannot raise their quotas in kind, they must commute for them in money to be employed in procuring all things requisite for the service. For the possessions of the subjects cannot be kept secure otherwise than by the defense of arms.

These precautions often become doubly necessary as a siege is sometimes protracted beyond expectation, the besiegers resolving to suffer themselves all the inconveniences of want sooner than raise the siege, if they have any hopes of reducing the place by famine. Edicts should be issued out requiring the country people to convey their cattle, grain, wine and all kinds of provisions that may be of service to the enemy, into garrisoned fortresses or into the safest cities. And if they do not comply with the order, proper officers are to appointed to compel them to do it. The inhabitants of the province must likewise be obliged to retire with their effects into some fortified place before the irruption of the enemy. The fortifications and all the machines of different kinds must also be examined and repaired in time. For if you are once surprised by the enemy before you are in a proper posture of defense, you are thrown into irrecoverable confusion, and you can no longer draw any assistance from the neighboring places, all communication with them being cut off. But a faithful management of the magazines and a frugal distribution of the provisions, with proper precautions taken at first, will insure sufficient plenty. When provisions once begin to fail, parsimony is ill-timed and comes too late.

On difficult expeditions the ancients distributed the provisions at a fixed allowance to each man without distinction of rank; and when the emergency was past, the government accounted for the full proportions. The troops should never want wood and forage in winter or water in summer. They should have corn, wine, vinegar, and even salt, in plenty at all times. Cities and fortresses are garrisoned by such mcn as are least fit for thc service of the field. They arc provided with all sorts of arnms, arrows, fustibali, slings, stones, onagri and balistae for their defense. Great caution is requisite that the unsuspecting simplicity of the inhabitants be not imposed on by the treachery or perjury of the enemy, for pretended conferences and deceitful appearance of truces have often been more fatal than force. By observing the foregoing precautions, the besieged may have it in their power to ruin the enemy by famine, if he keeps his troops together, and if he divides.them, by frequent sallies and surprises.

METHODS TO PREVENT MUTINY IN AN ARMY

An army drawn together from different parts sometimes is disposed to mutiny. And the troops, though not inclined to fight, pretend to be angry at not being led against the enemy. Such seditious dispositions principally show themselves in those who have lived in their quarters in idleness and effeminacy. These men, unaccustomed to the necessary fatigue of the field, are disgusted at its severity. Their ignorance of discipline makes them afraid of action and inspires them with insolence.

There are several remedies for this evil. While the troops are yet separated and each corps continues in its respective quarters, let the tribunes, their lieutenants and the officers in genera4 make it their business to keep up so strict a discipline as to leave them no room to harbor any thoughts but of submission and obedience. Let them be constantly employed either in field days or in the inspection of their arms. They should not be allowed to be absent on furlough. They should be frequently called by roll and trained to be exact in the observance of every signal. Let them be exercised in the use of the bow, in throwing missile weapons and stones, both with the hand and sling, and with the wooden sword at the post; let all this be continually repeated and let them be often kept under arms till they are tired. Let them be exercised in running and leaping to facilitate the passing of ditches. And if their quarters are near the sea or a river, let them all, without exception, be obliged in the summer to have the frequent practice of swimming. Let them be accustomed to march through thickets, inclosures and broken grounds, to fell trees and cut out timber, to break ground and to defend a post against their comrades who are to endeavor to dispossess them; and in the encounter each party should use their shields to dislodge and bear down their antagonists. All the different kinds of troops thus trained and exercised in their quarters will find themselves inspired with emulation for glory and eagerness for action when they come to take the field. In short, a soldier who has proper confidence in his own skill and strength, entertains no thought of mutiny.

A general should be attentive to discover the turbulent and seditious soldiers in the army, legions or auxiliaries, cavalry or infantry. He should endeavor to procure his intelligence not from informers, but from the tribunes, their lieutenants and other officers of undoubted veracity. It would then be prudent in him to separate them from the rest under pretence of some service agreeable to them, or detach them to garrison cities or castles, but with such address that though he wants to get rid of them, they may think themselves employed by preference and favor. A multitude never broke out into open sedition at once and with unanimous consent. They are prepared and excited by some few mutineers, who hope to secure impunity for their crimes by the number of their associates. But if the height of the mutiny requires violent remedies, it will be most advisable, after the manner of the ancients, to punish the ring-leaders only in order that, though few suffer, all may be terrified by the example. But it is much more to the credit of a general to form his troops to submission and obedience by habit and discipline than to be obliged to force them to their duty by the terror of punishment.

MARCHES IN THE NEIGHBORHOOD OF THE ENEMY

It is asserted by those who have made the profession their study that an army is exposed to more danger on marches than in battles. In an engagement the men are properly armed, they see their enemies before them and come prepared to fight. But on a march the soldier is less on his guard, has not his arms always ready
