One theme presented by supporters of the American empire is the U.S. military is invincible and can never lose unless stabbed in the back by impatient politicians. They claim the U.S. military never lost a battle during the entire Vietnam war. On August 30, 2011, President Barack Obama proclaimed to a gathering of veterans: " But let it be remembered that you won every major battle of that war. Every single one ." Vietnam vet Senator John McCain repeated this lie in a 2013 article in the "Wall Street Journal." This myth was disputed by America's most decorated officer of that war, Colonel David Hackworth, in his book "About Face." The U.S. military had every advantage, yet mistakes were made and battles lost. Internet research turns up these 112 lost battles of the Vietnam war:

1. Battle of Ap Bac - In January 1963, American advisors launched a battle after they pressured reluctant South Vietnamese officers to use American air mobility assets to destroy the Viet Cong. The attack was a disaster in which the VC mauled a far larger force while shooting down five American helicopters (pictured) and damaging eight, while killing three Americans and wounding eight.

2. T he Sinking of the USNS Card - This World War II aircraft carrier was later used as a transport for American military cargo. On May 2, 1964, it was moored in a heavily defended harbor in the Saigon River. Two VC commandos crawled down a sewer pipe and attached explosives to the ship. The explosion knocked a huge hole in the hull and killed five American crewmen, causing the ship to sink 45 feet to the river bed.

3. Attack on Bien Hoa Airbase - On November 1, 1964, Viet Cong squads shelled the airfield at Bien Hoa with mortars. The attack began shortly after midnight and lasted 20 minutes. It was estimated that there were three 81mm mortars. The attack was devastating as 27 aircraft were hit, including 20 B-57s (5 destroyed), 4 helicopters, and 3 A-1H Skyraiders. A fourth Skyraider crashed trying to take off. Five Americans and two Vietnamese were killed, and 43 wounded.

4. Attack on Qui Nhon Barracks - The US Army leased a hotel to house a helicopter field support unit. On February 10, 1965, Vietcong sappers killed its two guards, placed two large satchel charges, and blew up the hotel, killing 23 Americans and seriously wounding another 21.

5. Attack on Camp Holloway - In 1962, the U.S. Army established an airfield near Pleiku in central South Vietnam, which grew to include logistics elements and a large advisory group. In early 1965, some 300 Viet Cong slipped past ARVN guards and swept through the camp killing 8 Americans, wounding 126, destroying 10 aircraft and damaging 15 more. The Viet Cong withdrew to avoid battling reinforcements, with few losses.

6. Attack on Xom Bong - The " Rolling Thunder " bombing campaign began on Mar 2, 1965 as dozens of American jets attacked an ammunition storage facility 35 miles north of the DMZ. Several buildings were destroyed, but two F-100D and three F-105D fighter aircraft were shot down by ground fire.

7. The Dragon's Jaw - On Apr 3, 1965, the U.S. military conducted the first of hundreds of bombing raids to destroy the Thanh Hoa Bridge in North Vietnam. Thousands of bombs were dropped and eleven American aircraft shot down with several more damaged beyond repair until the iron bridge finally fell in 1972.

8. Battle of Dong Xoai - Soon after American combat brigades arrived in South Vietnam, the NVA attacked this large, strategic base defended by ARVN units supported by American Special Forces and airpower. The base was overrun with hundreds of casualties while two dozen Americans died in combat and helicopter crashes, with even more wounded or missing.

9 . Sapper Attack on Da Nang Airbase - North Vietnamese Army (NVA) sappers infiltrated this airbase on July 1, 1965. They destroyed three large C-130 transport aircraft, three F-102 fighters, and damaged three more F-102s. The sappers escaped leaving behind one dead.

10

. Operation Spring High - President Johnson authorized a punitive strike on two new SAM sites in North Vietnam considered the likely culprits behind the downing of a USAF F-4. On July 27, 1965, Operation Spring High was launched as 46 USAF F-105 fighter-bombers attacked SAM missile sites 6 and 7. Six F-105s were lost to ground fire during the mission while later bomb damage assessment photos showed that neither site had missile systems installed.

11 . Iron Hand Air Strikes - American aircraft had suffered losses from North Vietnamese Surface-to-Air Missile (SAM) systems. On August 13, 1965, the Navy aircraft carriers USS Coral Sea and USS Midway launched 76 low-level " Iron Hand " missions to seek out and destroy SAM sites. Five aircraft and three pilots were lost to enemy guns, and seven other planes were damaged, but no SAMs were discovered.

12 . Death of Supply Column 21 - Operation Starlite was the first major Marine Corps operation in Vietnam, and fighting was tougher than expected. A ship landed an armored supply column to support combat forces, which became lost and was attacked in a rice paddy on Aug 18, 1965. Five of the seven armored vehicles were destroyed (including two tanks) during a day long firefight. Five of the 27 Marines were killed and 17 wounded as they held off the enemy until daybreak.

13. The Battle of An Ninh - The newly arrived 101st Airborne employed the new helo assault tactic to surprise the NVA. The plan was to fly an entire battalion into an area where a strong enemy presence was suspected. The intelligence proved accurate as the first company landed next to a large NVA unit and was pinned down. As the second wave attempted to land, several helicopters were shot down and the rest fled without dropping troops after all suffered damage. Helicopters were borrowed from other units and troops eventually landed further away and rushed to save the surrounded company that was nearly overrun. (pictured above). While the NVA eventually fled, this poorly planned battle cost 22 American lives.

14. The Battle of Ia Drang - This was one of many disastrous airmobile assaults, when infantry helicoptered into a remote area and encountered a larger enemy force with ample ammunition. On Nov 14, 1965, 450 soldiers from the 1st battalion of the 7th Cavalry landed at LZ X-ray and found itself surrounded with little ammunition and no heavy firepower. It was nearly overrun while suffering 79 killed and 121 wounded, and survived only by diverting all available air support in Vietnam. The 7th Cavalry left the area after declaring victory, while survivors pondered the wisdom of an attrition strategy using American foot infantry.

15 . Battle for LZ Albany - The 1st battalion of the 7th Cavalry barely survived its now famous 1965 battle in the Ia Drang valley. After saving its 1st battalion, the exhausted 2nd battalion headed for LZ Albany for an aerial extraction. It was in a long column in open terrain when it ran into a concealed NVA battalion, which attacked and shot it to pieces during a bloody battle that claimed the lives of 155 Americans, with 124 wounded.

16. Battle of Ap Nha Mat - On Dec. 5, 1965, the 2nd battalion of the US Army's 2nd Infantry Regiment was searching for an NVA regiment and found it, dug in bunkers all around them. An intense firefight erupted resulting in 43 Americans killed and 119 wounded as some soldiers fell back leaving dead and wounded behind. The NVA withdrew and Army Generals later claimed that 301 NVA were killed, although few bodies were found.

17 . Attack on Marble Mountain - Some 90 Viet Cong sappers infiltrated this huge Marine Corps airfield and destroyed 19 helicopters and damaged 35 (11 of them severely). After this 30-minute rampage, the Viet Cong withdrew, leaving behind 17 dead and 4 wounded. American casualties were 3 killed and 91 wounded.

18. Operation Utah - On March 4, 1966, the 2nd battalion of the 7th Marines helicoptered into an area near Quang Ngai to investigate reports of an NVA regiment in the area. They found it dug into fortifications around Hill 50. Their attacked failed and the Marines fell back, but were surprised when the NVA counterattacked. The battalion was in trouble and more Marine units were flown in to join the battle. The enemy withdrew, but only after the Marines lost 98 dead, 278 wounded, with several aircraft destroyed.

19. Operation Indiana - On March 28, 1966, the 1st battalion of the 7th Marines helicoptered into the Quang Ngai area to establish a blocking position. Its Company C encountered a VC heavy weapons battalion and attacked, but was shot up and pinned down. It suffered heavy causalities and was forced to withdraw before nightfall leaving most of its dead behind. The Vietcong withdrew that night after having killed 11 Marines and wounding 55.

20. LZ Hereford Overrun - During Operation Crazy Horse, the 1st Battalion of the 12th Cavalry was out searching for the enemy. A hundred NVA slipped past and quickly overran a mortar platoon, killing 16 GIs while wounding five soldiers as they escaped.

21. Battle of Xa Cam My - A battalion from the 1st Infantry Division conducted another "search and destroy" sweep. Its three companies were deployed miles apart in hopes the NVA would attack one. They surrounded and blasted Charlie company, killing 38 and wounding 71 of its 134 soldiers before its other two companies came to the rescue.

22. Assault at Srok Dong - In June 1966, units from the 18th Infantry Regiment were assigned to escort engineers to repair a bridge. They encountered dug-in Viet Cong and attacked. All four supporting tanks were disabled as soldiers fought bravely for three days and suffered 34 dead and 84 wounded.

23. Patrol Surrounded - On July 3, 1966, a 22-man patrol from the Army's 35th Infantry Regiment found itself surrounded and pinned down by NVA fire. They were rescued the next morning, but 15 were dead and 4 wounded while several more Americans were killed during the difficult rescue.

24. Operation Paul Revere IV - Two cavalry battalions swept the Cambodian border area in search of the enemy. None were found, until Company C ran into a large force near Duc Co. Details are scarce, but two platoons were overrun and destroyed; only one soldier survived. The American dead were so numerous that they were hauled away in external cargo nets by helicopters.

25. Battle of Cu Nghi - As the 7th Cavalry began Operation Masher, a CH-47 helicopter was shot down. A company of soldiers was flown to the rescue, but they were shot up and pinned down. More units hastily arrived and found two battalions of entrenched NVA fighters firing away at troopers scattered around an area that became known as "the graveyard." Several helicopters where shot down during this three-day melee that left 140 Americans dead and 220 wounded.

26. Helicopter Valley - On July 15, 1966, Operation Hastings began as the 3rd Battalion of the 4th Marines helicoptered into small LZ Crow. Enemy ground fire caused five large Marine CH-46A helicopters to crash , killing 13 Marines and seriously wounding a dozen more.

27. Battle of Ho Bo Woods - On July 19, 1966, Company A, 1st Bn, 27th Rgt, 25th Division helicoptered into an LZ with 92 soldiers on a search and destroy mission. There is no account of what happened next, except that 25 were killed and 32 wounded as the company fled aboard helicopters, leaving 16 of their dead behind.

28. Battle of Bong Trang - In late August 1966, a squad from of the 1st Infantry Division ventured into the dense jungle near Saigon in search of the enemy. It wandered into a large NVA base camp and was shot up. Reinforcements poured into this confusing, bloody, two-day battle that left 45 Americans dead, hundreds wounded, with the loss of a helicopter and several armored vehicles.

29 . Operation Crimson Tide - On Oct 18, 1966 the first mission to rescue an American POW was launched . It ended in disaster, with 12 killed, 17 missing, two helicopters shot down, and no prisoners rescued.

30. " Black Friday " - Strike aircraft losses were common, but on December 2, 1966 the U.S. Air Force lost five aircraft and the Navy lost three aircraft to surface to air missiles or anti-aircraft gun fire. Air Force losses included three F-4Cs, one RF-4C, and an F-105. The Navy lost one F-4B and two Douglas A-4C Skyhawks.

31. Operation Tuscaloosa – In January 1967, the 2nd Battalion 5th Marines sought to destroy elusive NVA elements. They chased some to the shallow Song Thu Bon River and decided to cross. The NVA were waiting and fired away at the exposed Marines struggling to charge across. The Marines succeeded by employing air and artillery, but lost of 17 KIA and 52 WIA in a heroic yet foolish attack .

32. Kon Tum Attack - During Operation Sam Houston, elements of the 4th Division swept along the Cambodian border. The isolated 1st Platoon from Company C, 2/8 Infantry was attacked . Only one soldier remained unscathed as 21 were killed and 14 wounded but the platoon held on until rescued at daybreak.

33 . Attack at Binh Duong - On Feb 26, 1967, a Viet Cong battalion nearly overran Alpha Company, 4th Battalion, 9th Regiment, of the Army's 25th Division. The VC slipped past camp defenses in a surprise attack that killed 19 Americans and several ARVN soldiers.

34. Operation Beau Charger - This was part of a larger operation near the DMZ. The Marines launched 14 helicopters from ships offshore to deposit 1st Battalion, 3rd Marines into LZ Goose. Unfortunately, the NVA were there and opened fire on the helicopters as they landed on May 18, 1967. Half were damaged and only a few dozen Marines landed. This quickly became a complex rescue operation that cost the lives of 85 Marines with hundreds wounded.

35 . Operation Hickory - In May 1967, U.S. Marines were ordered to cross into the DMZ and destroy the NVA. Several days of frontal assaults killed lots of NVA lodged in fortifications, but also killed 142 Marines and wounded 896 until the marines withdrew after ten days of pointless attacks.

36. Battle of Plei Doc - During Operation Francis Marion, B Co., 8th Inf., 1st Bde., 4th Inf. Div went into the dense jungle near in Cambodian border to make contact with the NVA. On May 18, 1967, its D Platoon went on a short patrol and chased a lone NVA scout, who led them into an ambush. The platoon was surrounded and wiped out with 22 killed and one missing. Seven wounded survivors hid from the NVA that night until their battalion came to the rescue, which lost a total of 48 killed and 96 wounded during this battle .

37 . Battle near Vinh Huy - During Operation Union II, six rifle companies from the 5th Marines swept the Que Son Valley in search of the enemy. They located a large enemy force 1000 yards ahead across an open rice paddy. After some air and artillery strikes, three companies were ordered to charge across the open ground, and were shot to pieces. The bloodied Marines fell back during this June 2, 1967 battle with 71 KIA and 139 wounded.

38. Operation Concordia - The 9th Infantry Division sought out the Vietcong in the Delta region. On June 19, 1967, Company A of 4/47th Infantry walked into an L-shaped ambush and was shot up and pinned down. Other units rushed to help as the Vietcong withdrew after killing 48 Americans and wounding dozens more.

39. Coast Group 16 Naval Base Destroyed - On August 7, 1967, the Vietcong launched a surprise attack on the coastal gunboat base at Tra Khuc and quickly seized it. All but one of the base buildings were destroyed as friendly gunboats arrived and engaged the invaders aboard the base. The fighting killed 14 South Vietnamese sailors along with an American officer and 20 civilians, while 30 Vietcong prisoners were freed.

40. August 1967 Air Battle - This war produced two American "Ace" fighter pilots (i.e. five or more aerial shoot downs), yet the North Vietnamese had 16, including Nguyen Van Coc (right), the top Ace of the war with nine kills. On Aug. 23, 1967, Coc led several MIG fighters to intercept a group of 40 American aircraft on a bombing mission. They shot down three American F-4D fighters and one F-105D fighter-bomber without losing a single MIG. Eight American aviators were killed or captured.

41. Battle of Prek Klok - During Operation Junction City, Company B from the 1st Battalion/16th Infantry went in search of the NVA. Independent accounts cannot be found, yet the Army's official history notes the company was blasted and nearly surrounded until rescued when another company came to its aid, allowing it to retreat. Company B was extracted by helicopter after suffering 25 dead and 28 wounded. Army Generals declared victory and awarded the company commander a silver star.

42. Kingfisher Battle - In 1967, "Operation Kingfisher" was launched to destroy NVA forces just south of the DMZ. On Sept. 21st, the 2nd battalion, 4th Marines began a "search and destroy" mission and quickly encountered the entrenched 90th NVA regiment. The Marines lacked tank support because recent rains limited road mobility, while the dense vegetation and close proximity of the enemy restricted air and artillery support. After a day-long battle, the Marines had suffered at least 16 dead and 118 wounded while trying to break out of the enemy's kill zone. The battalion withdrew at dusk, although flee may be a better term since 15 dead Marines were left behind. Details are sketchy , but the battalion didn't return to collect its dead until three weeks later. Veterans of the battle state they lost 34 KIA that day.

43. Assault on Hill 830 - During Operation Greeley, the 4th Battalion of the 503rd Infantry (Airborne) marched through dense foliage in search of the enemy. On July 10, 1967, the battalion encountered NVA dug into Hill 830 and attacked . The battalion was pinned down for hours by heavy enemy fire and suffered 25 killed and 62 wounded until the NVA withdrew at nightfall.

44. Rocket Attack on Da Nang - On July 15, 1967, the NVA conducted a major rocket bombardment on the key U.S. airbase at Da Nang. A total 83 NVA 122mm and 140mm rockets hit the base just before dawn, resulting in 8 killed, 175 wounded, 10 aircraft destroyed and 49 damaged.

45. The Battle of Thon Cam Son - In July 1967, the 2nd battalion of the 9th Marines crossed into the DMZ to find the NVA. They found abandoned base camps and bunkers because the NVA had pulled out and moved around behind them. The Marines had to fight their way back home, and more than half the unit bled as it lost 41 killed and 355 wounded.

46. A MIG Day - On August 30, 1967, the U.S. Air Force launched a second attack on a power plant near Hanoi. Two MIGs slipped into the formation of 28 aircraft and shot down two F-105 fighter bombers. The strike was aborted and several F-105s circled to support the rescue effort. Two more MIGs swooped down and chased them away while shooting down another F-105 and damaging another with no MIGs lost.

47. Battle for Nui Ho Khe (Hill 88) - Marines were concerned that enemy units near their big Con Thien base threatened their main supply route. On Sept 10, 1967, the 3rd battalion of the 26th Marines ventured forward to secure Hill 88. It was surprised to encounter an entire NVA regiment, which counterattacked causing a bloody fight in which 3/26 suffered 300 casualties (40% including 37 KIA) and lost several tanks. It withdrew to Hill 48 where it made a successful last stand. While the NVA suffered more causalities, poor intel resulted in this clumsy assault that failed to reach its objective.

48. Operation Medina – In October 1967, three battalions of U.S. Marines entered the Hai Lang Forest to find and kill NVA troops. They found the terrain difficult and lost 34 KIA and 143 WIA as they stumbled through the thick jungle fighting an elusive enemy.

49. Commando Club Disaster - On Nov 18, 1967, the USAF hoped to employ its new "Commando Club" radar guided bombing system to attack the NVA MIG fighter base at Phuc Ye. This was thwarted when two MIGs swooped down on the formation of 20 attacking USAF F-105s and shot down two aircraft while a swarm of 13 SAMs launched from the airbase downed two more approaching F-105s. The remaining strike force jettisoned their bombs before reaching the target area and turned toward home.

50 . Slaughter at LZ Margo - The 2nd battalion of the 26th Marines helicoptered into LZ Margo near the DMZ on a standard search and destroy mission. Contact was light over the next three days as units swept the area. On Sept. 16, 1968, the battalion received an order from higher headquarters to withdraw into the small LZ where they had arrived, because a big B-52 air strike was planned in the area. Marines were worried because they were tightly grouped and the ground was rock hard so they couldn't dig in. They knew the NVA kept them under observation and were a perfect target for a mortar barrage. A short time later, hundreds of mortar rounds tore into the tightly packed Marines, killing 30 and wounding nearly 200 until the NVA ran out of ammo.

51. Operation Swift - U.S. Marines fought tough battles along the DMZ when NVA units moved across the border to inflict heavy casualties. Marine Generals sent rifle companies with ~140 Marines to search for and destroy the NVA intruders with artillery and airpower. This was effective, but larger NVA units sometimes trapped them in kill zones. In September 1967, they ambushed two Marine companies in the Que Son Valley. Operation Swift was launched to save them from destruction, but the two companies sent to the rescue were mauled. The end result was 127 Marines killed and 362 wounded. The NVA suffered more casualties, but accomplished their mission and withdrew northward.

52. Convoy Ambush near An Khe - In Sept 1967, 39 trucks from the U.S. Army's 8th Transportation Group were returning home after delivering supplies to Plekiu. They were escorted by two gun jeeps in an area considered mostly secure by the presence of the 1st Calvary Division. A Viet Cong company ambushed this big convoy in broad daylight. Seven Americans were killed, 17 wounded, and 30 vehicles were damaged or destroyed. The VC quickly disappeared and no evidence of enemy casualties were found.

53 . Task Force Black Mauled - Half of the 1st Battalion/501st Regiment/173rd Airborne Brigade went in search for the NVA who had recently attacked their base. They ran into two NVA battalions, who shot them up from three directions. The rest of the battalion was sent to save them, and withdrew with 20 dead, 154 wounded, and two missing.

54. Operation Essex - In early Nov 1967, two companies from 5th Marines walked into well planned ambushes near An Hoa and were shot up and pinned down overnight. Other companies came to the rescue as 37 Marines died and 122 were wounded.

55. Battle near Ap Bac - The U.S. Army's 9th Infantry Division operated in the marshy delta region of southern Vietnam, often with Navy river patrol boats. During a routine battalion sweep, Alpha company from the 2nd Brigade crossed an open rice paddy and encountered Viet Cong ready to fight from concrete bunkers. Most of the company was wiped out in the first five minutes, and rest pinned down in the kill zone for hours until other companies arrived. This battle left 40 American dead and 140 wounded.

56. Battle for Hill 861 - In 1967, Bravo Company, 1st battalion, 9th Marines went to search for caves on Hill 861. After a skirmish, the company attacked up the hill without knowing that it had encountered a large enemy force. Most of Bravo was wiped out and the survivors were pinned down until rescued by Kilo company that night.

57. Operation Badger Tooth - The NVA spent a year covertly fortifying the village of Tham Khe. The day after Christmas 1967, the 3rd Battalion, 1st Marines landed by ship to sweep the area without armor support. The Marines were surprised by heavy enemy fire when they approached Tham Khe, yet kept attacking until the enemy fled, leaving 48 Marines dead and 88 wounded.

58. Slaughter in an LZ - On Jan. 10, 1968, a hundred soldiers from the U.S. Army's 60th Infantry Regiment helicoptered onto a rice paddy and chaos ensued as the Viet Cong was ready for them. At least one helicopter was shot down and many more damaged as troops remained pinned down for 18 hours, suffering 34 killed and 59 wounded until the enemy withdrew.

59. Overrun in Happy Valley - During the first two weeks of 1968, 69 soldiers from the 196th Infantry Brigade died in heavy fighting in the Hiep Duc Valley, Quang Tin Province. On January 9-10, Alpha and Delta companies from its 3/21 Infantry battalion were overrun. The Delta company commander and 27 men were killed . Dozens were wounded and eight Americans taken prisoner as survivors held out in small groups overnight until rescued the following day.

60. Ambush at Hoc Mon - In 1968, 92 American soldiers of C Company, 4th Battalion, 9th Infantry Regiment, 25th Division began a search-and-destroy mission near Saigon. They were looking for a Viet Cong force that had been firing rockets into their Tan Son Nhut Air Base. As they rushed along a road without flank security to catch up with their battalion, they ran into an ambush . Within eight minutes, 49 American soldiers were dead or dying, and 29 were wounded.

61 . Battle of Kham Duc - This large Special Forces camp was abandoned as it was overrun , despite reinforcement by an American infantry battalion from the 196th brigade. Hundreds of friendly civilians and militiamen were left behind as Americans escaped aboard helicopters and C-130s; with two C-130s shot down resulting 150 dead.

62. Khe Sahn Village Overrun - A large village three kilometers from the famous Khe Sahn military base was defended by 160 local troops, plus 15 American advisors and heavy artillery from the base. In January 1968, it was attacked by a ~300-man NVA battalion. Reinforcements were dispatched aboard nine UH-1 helicopters, but were wiped out after landing near the NVA, along with one helicopter. A small ground rescue force from the nearby base was repulsed, while the survivors from the village assault fled to the Khe Sahn base.

63. Kontum Airfield Attacked - On Jan. 10, 1968, VC sappers infiltrated the big Kontum airfield and destroyed seven helicopters and damaged eleven others, while destroying several buildings and killing ten Americans.

64. Chu Lai Attack - In the early morning of Jan. 31, 1968, the Vietcong fired 48 122mm rockets at the Marine Corps airbase at Chu Lai while sappers attacked. They exploded the main ammo dump that set off 600 tons of bombs. This attack flattened several hangars, damaged buildings, destroyed five F-4 fighters and damaged 18 other aircraft, while killing three officers and wounding several enlisted.

65. Echo Relief Force Wiped Out - In February 1968, a Marine outpost near Da Nang was in danger of being overrun. A Marine captain led 16 Marines on foot to reinforce them, but ran into a much larger NVA force and they were slaughtered . Twelve Marines were killed, three escaped, while two were taken prisoner and died in captivity.

66 . Battle of the Slopes - A company of American paratroopers was searching for the NVA in rough terrain when it was attacked by a large force. It suffered 76 KIA as it was nearly overrun, with two platoons wiped out. Newly arrived airborne officers had ignored warnings that they should maneuver as battalions because the NVA units in that area were larger, aggressive, and would attack a lone rifle company.

67. Battle of No Goi Island - The Viet Cong liked to fortify ambush sites and wait for the Americans to discover them. During Operation Allen Brook, three battalions of Marines swept through No Goi Island and found lots of Viet Cong ready to fight from bunkers near the village of Le Bac. During several days of bloody assaults, the Marines suffered 138 killed and 686 wounded (576 seriously) before the surviving Viet Cong fled. The extreme heat resulted in another 283 Marines evacuated due to heat stroke. Having suffered 50% causalities, Allen Brook was halted until fresh Marine units arrived.

68. Battle at the Ben Cui Rubber Plantation - American mechanized units had the firepower and mobility to rout any NVA force. An exception occurred in 1968 during a routine road sweep when Company C, 1st Bn (Mech), 25th Division ran into an aggressive NVA regiment. It quickly lost 5 APCs (right), with 17 killed (leaving just one officer), and two dozen wounded before it retreated to its home base, leaving most of its dead behind.

69. Battle of Dai Do - A Marine Corps infantry battalion was mauled and forced to retreat after a disorganized attempt to dislodge a large North Vietnamese force near the DMZ. The Marines suffered 81 KIA and 397 wounded while killing hundreds of NVA.

70. Battle of Ong Thanh - After minor enemy contact the previous day, a battalion commander led 155 American soldiers single-file into the bush to destroy the enemy. They ran into an NVA regiment with some 1400 men. Alpha company was wiped out in 20 minutes, and by sundown, 59 American soldiers lay dead with 75 wounded. An excellent documentary is on-line where survivors describe the onslaught.

71. O peration Delaware - In this April 1968 offensive, the U.S. Army learned that mountain jungles allow concealed anti-aircraft weapons to easily shoot down low-flying aircraft. Units of the 1st Cavalry Division helicoptered into rugged terrain and killed hundreds of NVA as they withdrew to Laos. However, the NVA shot down a C-130 transport, two fighter-bombers, eight large helicopters, nearly two dozen UH-1 helicopters, and seriously damaged three dozen other helicopters, whose crashes left 47 Americans MIA. The NVA also killed 142 Americans, wounded 731, and returned to the area as the 1st Cav withdrew after three weeks of fighting.

72, Battle for Chu Moor Mountain - In April 1968 near the Cambodian border, the 1st Battalion of the 22nd Infantry discovered well-armed NVA dug into a mountain. They launched several bloody attacks and fended off counterattacks for days suffering 31 killed and hundreds wounded. Other battalions were flown in and suffered casualties until all units were pulled back and a B-52 strike ordered as the NVA withdrew.

73. Battle of FSB Maury I - In the early morning of May 9, 1968, Battery B and C of 7/11 Artillery were attacked by the Vietcong. The firebase was nearly overrun with 14 American KIA, 62 WIA, and five 105mm howitzers destroyed, while only 18 enemy were killed before they withdrew.

74 . Operation Houston II - In May 1968, as Mike company from the 3rd Battalion, 5th Marines moved up a ridge called Hill 1192, they wandered into an NVA base camp and were shot to pieces with 14 killed and dozens wounded. Three helicopters were shot down attempting to rescue wounded Marines. The surviving marines remained pinned down and bleeding for several days until rescued by another company.

75. Camp Evans Destroyed - On May 19, 1968, the VC attacked the main base of the 1st Cav with five 122mm rockets. This set off a chain reaction that blew up the main ammo dump with about 10,800,000 pounds of ammunition, which was poorly located next to the airfield. This destroyed 40 helicopters and left most of the base in shambles.

76. Battle for LZ Loon - The Marines landed on Hill 672 to build an artillery fire support base. The NVA objected, and sent a battalion to attack the two undermanned companies from the 4th Marines. After a day of heavy fighting that included NVA artillery fire, half the Marines were casualties. It was decided to abandon the hill by helicopter, leaving most of the dead behind.

The platoon was wiped out during a three-hour battle that left 31 Marines KIA, one taken prisoner, while nine Marines escaped back to their base.

83. Battle of Thon La Chu - The 1968 Tet offensive caught the U.S. military by surprise, and the NVA captured the city of Hue. During this chaos, the cavalry was sent to save the Marines as the Army's lightly armed 2nd battalion/12th Cavalry flew to the rescue in helicopters. After landing, it charged across an open rice paddy without its customary artillery or air support and suffered considerable casualties. The enemy had superior numbers, superior positions, and enough firepower to encircle the battalion.

This resulted in 41 KIA, 32 wounded, with 2 of 15 MIAs later rescued by helicopters. The battalion commander was relieved of duty.

86. Attack on Nui Ba Den - A hundred NVA launched a surprise assault on a poorly defended American signal intelligence station atop Nui Ba Den mountain. The base was quickly overrun and burned to the ground. The NVA killed 24 Americans, wounded 35, and 2 were taken prisoner as the NVA withdrew. Most Americans survived in one bunker or by fleeing the base and hiding among boulders. Some refer to the battle as a massacre because the attack was so sudden that many soldiers had no rifles to defend themselves.

87. Overrun at Ap Trang Dau - On the night of Sep 5, 1968, nine companies from the 101st Airborne division converged on the village of Ap Trang Dau, trapping a large enemy force.

They destroyed nine large CH-47 helicopters, heavily damaged three more, and caused minor damage to two others. (photos are here ) 14 Americans were killed and 29 wounded during the three-hour battle.

93. Battle of Hamburger Hill - A battalion from the 101st Airborne (3/187) encountered stiff resistance on rugged Hill 937. It was unable to capture the summit due to steep, dense terrain, well-built enemy bunkers, a deadly friendly fire incident, and fierce NVA defenders. A second battalion (1/506) was sent to attack from the south, but it suffered the same fate. Small NVA counterattacks caused confusion and several more deadly friendly fire incidents. Aggressive American commanders ordered repeated attacks for three days until 3/187 had lost 60% of its men and withdrew, while 1/506 remained pinned down.

More battalions arrived to join the attack. ARVN scouts reported the NVA had left the mountain, nevertheless, a two hour aerial bombardment commenced before the American battalions walked up Hill 937 to proclaim victory, and then withdrew a few days later. These frontal assaults resulted in 84 American dead with 480 wounded, and the loss of several helicopters, leading to the nickname "Hamburger Hill" where GIs were ground up. Given the heavy causalities suffered for nothing gained due to an NVA " hill trap " maneuver, this was a defeat .

94. The Battle for Nui Yon Hill - On May 5, 1969, units of the 1st Squadron, 1st Cavalry were ordered to clear Viet Cong from Nui Yon Hill, which they recently captured from the ARVN.

A lieutenant who heroically led a retreat of the survivors was almost court-martialed by senior officers trying to cover-up this disaster.

99. Firebase Kate Captured - In September 1969, 30 American soldiers with 150 local Montagnards established Firebase Kate near the Cambodian border. The base had no road access and was beyond the range of artillery support from other bases. The American officers at the base knew it was very vulnerable and within a month thousands NVA surrounded the base and began a siege. After five days of artillery and mortar attacks, helicopter resupply ended and the Americans destroyed their artillery and ammo and escaped.

100. Firebase Airborne Overrun - There are several short, vague accounts about how this artillery firebase was overrun on May 13, 1969. One veteran believes it was bait to draw the NVA into combat. VC sappers slipped inside its weak defenses and exploded the artillery ammunition dump, killing a dozen and causing confusion. The NVA swept through the base at night killing and wounding most defenders and destroying its big guns. Many Americans managed to hide until the NVA left before dawn, so the base was never officially captured. However, it was wrecked and later abandoned.

101. FSB Rifle Overrun - During the early morning hours of February 11, 1970, Fire Support Base Rifle was overrun by the NVA. Eleven Americans were killed and the base leveled.

102. Cambodian Excursion - In May 1970, the 1st Cav invaded Cambodia in search of enemy base camps. Bravo Company from the 5th Battalion 12th Cav was searching for a heavy machine gun that fired at aircraft near its newly established firebase. It was assisted by a light spotter plane, which located the machine gun when it was shot down by it, killing two Americans. A helicopter dropped off reporters to cover the action, but was shot down as it departed, killing four. The infantry soon learned the NVA were all around, and spent the day and night getting shot up until rescued by an armored unit, with 14 KIA and dozens wounded.

103 . Operation Lam Son 719 - In early 1971, a major offensive was launched into Laos to sever the Ho Chi Minh Trail supply line. The United States provided logistical, aerial, and artillery support to the operation. American ground forces were prohibited by Congress from entering Laotian territory, but supported the offensive by rebuilding the airfield at Khe Sanh. South Vietnam provided its best units for this month long offensive , and the Pentagon was confident that American firepower would guarantee victory. After a series of lost battles, the South Vietnamese retreated back home after losing nearly 1,600 men. The U.S. Army lost 215 men killed, 1,149 wounded, 38 missing, and lost 108 helicopters while 7 American fighter-bombers were shot down.

106. Attack on FSB Henderson - As American troops withdrew from Vietnam, NVA sappers attacked this artillery base. They charged through the hilltop killing 27 soldiers from the 101st division and wounding 40. Most of the howitzers and artillery ammunition were destroyed by satchel charges before the NVA disappeared into the night.

107. Aerial Ambush over the DMZ - Before the 1972 NVA Easter Offensive, the NVA secretly moved several big SA-2 surface-to-air missile systems all the way down to the DMZ. On February 17th, 81 SA-2 missiles were unleashed at attacking American F-4 fighter-bombers, downing three of them and damaging several others.

108. Rescue of Bat 21 - On April 2, 1972, an Air Force EB-66 electronic warfare aircraft was shot down near the DMZ. Five airmen were killed while one officer parachuted into an area where the NVA was attacking. The Air Force imposed a standard no-fire zone with a 17-mile radius and diverted aircraft to aid the rescue. Hundreds of South Vietnamese soldiers died over the next few days as a result of their inability to obtain fire support. Five additional aircraft were shot down during rescue attempts, resulting in the deaths of 12 airmen and the capture of two others.

109. Battle for Firebase Ripcord - American Generals made one final attempt to block the Ho Chi Minh trail, and found more NVA troops than expected.

Dozens of helicopters were shot down or damaged, while several soldiers and all major items of equipment were left behind.

110 . June 1972 Air Battles - While superior aircraft of the USA won most air battles, the smaller MIGs flown by North Vietnamese pilots won many battles, which remain mostly hidden from history. An interesting website that documents combat losses sheds some light. It notes that MIGs shot down five American F-4 fighters on June 27, 1972, and cross referencing the date for American air victories shows no MIG kills.
