In early 1943, the 1st Ranger Battalion, known as Darby's Rangers, was still relatively unknown and rather untested. All of that was about to change.

The Rangers had been formed less than a year before at the insistence of Gen. George Marshall. Marshall believed that the Americans needed a commando unit and ordered Major Orlando Darby to make it happen. On June 19, 1942, the 1st Ranger Battalion was activated from "volunteers not adverse to dangerous action."

Though over 2,000 men had volunteered, only 575 officers and enlisted men were accepted into the battalion. The British Commandos then trained these men at their training facility at Achnacarry, Scotland.

Less than six months after their formation, the Rangers spearheaded the Allied invasion of North Africa by taking out Vichy French artillery batteries at Arzew, Algeria. In a quick but decisive move, the Rangers captured the guns and some 60 prisoners.

After helping secure the port facilities and a nearby town, the Rangers were withdrawn from action. They began an intense training period, focusing on forced marches and night fighting. Both would prove useful in the near future.

With the rapid advance of Allied forces across North Africa, and commanders unsure of what to do with a specialized raiding force like the Rangers, they were not involved in the ongoing combat.

That changed in February when the Rangers were called upon to conduct raids against Axis forces to gather intelligence and weaken enemy morale.

Darby devised a plan to attack the Italians at Sened Station.

Trucked to within 20 miles of their objective the Rangers set off in total darkness. The Rangers set a blistering pace and stealthily covered some fourteen miles before taking shelter among the rocks for the day.

Word was passed around for that night's mission — the Rangers would leave their mark.

"They've got to know that they've been worked over by Rangers," Capt. Roy Murray said. "Every man is to use his bayonet as much as he can. Those are our orders."

While his men concealed themselves among rocks and brush, Darby and his executive officer, Major Herman Dammer, conducted a leaders' reconnaissance of the Italian outpost.

With the final plan set, the Rangers prepared to move out as the sun set. Faces were blackened and anything that jingled or rattled was secured to ensure silence. Helmets had been traded for wool caps the night before.

Once the moon set, the Rangers began their movement toward the objective.

The raiding force consisted of three line companies and a detachment of 81mm mortars. They moved out three companies abreast, toward positions within 500 yards of the outpost.

Darby was able to track the movement of his men by an ingenious method. Using red-lensed flashlights covered with a shroud mounted on the pack of a few men, he was able to see when his units were in position. This also ensured that no man wondered off course.

When all was ready, Darby sent forward the order to fix bayonets and move out.

Slowly, silently, the Rangers crept toward the unsuspecting Italian garrison.

Some amount of noise must have made it to the Italians at their posts because they became suspicious. With the Rangers still some 200 yards out, Italian machine guns opened fire. In the pitch black, their fire was wild and inaccurate. The Rangers held their fire and continued to creep forward.

As the Rangers made it to within 50 yards of the wire, the Italian's fire became too close for comfort. Italian sentries called out into the night, "Qui va la? Qui va la?" ("Who goes there?")

All at once the Americans responded. The Rangers leapt up and charged across the short distance to the Italian perimeter. American Tommy Guns riddled the outpost as riflemen tossed hand grenades and stormed across the Italian defenses with their bayonets.

One Ranger, Cpl. James Altieri, stumbled into a trench and right on top of an Italian soldier. In the brief struggle, Altieri dispatched the man by stabbing him in the stomach. It was his first hand-to-hand kill. He immediately vomited before continuing the fight.

Altieri later described the fighting by saying, "We worked them over furiously, giving no quarter."

As the Rangers cleared the outpost, the 81mm mortars pounded the Italian positions and cut off their retreat.

In just 20 minutes, the Rangers were victorious. The Rangers had killed some 75 Italians and captured eleven more from the elite 10th Bersaglieri Regiment. The Italian artillery and machine guns were destroyed in place.

The victory had cost the Rangers one man and another 20 wounded.

As Darby conferred with the assault commanders and consolidated his position, he could hear the distant rumble of tracked vehicles — German armor. This was expected; the raid had been intended to draw out the Germans to help commanders determine their strength. But it also meant it was time for the Rangers to get out of Dodge.

Retracing their steps, the Rangers set out on a forced march back to the French outpost with their prisoners in tow.

The sudden ferocity with which the Rangers struck earned them the nickname "the Black Death" among the Italians.

The daring raid also garnered Darby and eleven other Rangers a Silver Star for gallantry.

Darby and the Rangers would see more intense combat in North Africa before spearheading assaults into Sicily and Italy.

Their success convinced the Army to stand up four more Ranger battalions in the European theatre.
