The Battle of Khe Sanh (21 January – 9 July 1968) was conducted in the Khe Sanh area of northwestern Quang Trị Province, Republic of Vietnam (South Vietnam), during the Vietnam War. The main US forces defending Khe Sanh Combat Base (KSCB) were two regiments of the United States Marine Corps supported by elements from the United States Army, the United States Air Force (USAF) and the RAAF, as well as a small number of Army of the Republic of Vietnam (ARVN) troops. These were pitted against two to three divisional-size elements of the North Vietnamese Peoples Army of Vietnam (PAVN).

The US command in Saigon initially believed that combat operations around KSCB during 1967 were part of a series of minor PAVN offensives in the border regions, but when the PAVN was found to be moving major forces into the area, the U.S. force at KSCB was reinforced. On 21 January 1968, the PAVN surrounded and besieged the Marine base. In the ensuing five months, KSCB and the hilltop outposts around it were subjected to daily PAVN artillery, mortar, and rocket attacks, and several infantry assaults. More than 274 U.S. troops were killed and more than 2,500 wounded.

To support the Marine base, the USAF undertook Operation Niagara, a massive aerial bombardment campaign. In the first three months, over 114,810 tons of bombs were dropped by US & allied aircraft and over 158,900 artillery rounds were fired in defense of the base. U.S forces lost one KC-130, three C-123 and 35 helicopters, while 23 aircraft and 123 helicopters were damaged.Throughout the campaign, US forces used the latest technology to locate and target PAVN forces, and logistical innovations to support the base.

In March 1968, a combined Marine–Army/ARVN task force launched an overland relief expedition (Operation Pegasus) that eventually broke through to the Marines at Khe Sanh.

American commanders considered the defense of Khe Sanh a success, but shortly after the siege was lifted, decided to dismantle the base rather than risk similar battles in the future. On 19 June 1968, the evacuation and destruction of KSCB began. Amid heavy shelling, the Marines attempted to salvage what they could before destroying what remained as they were evacuated. Minor attacks continued before the base was officially closed on 5 July. Marines remained around Hill 689, though, and fighting in the vicinity continued until 11 July until they were finally withdrawn, bringing the battle to a close.

In the aftermath, the North Vietnamese proclaimed a victory at Khe Sanh, while US forces claimed that they had withdrawn, as the base was no longer required. Historians have observed that the Battle of Khe Sanh may have distracted American and South Vietnamese attention from the buildup of Viet Cong (VC) forces in the south before the early 1968 Tet Offensive. Nevertheless, the US commander during the battle, General William Westmoreland, maintained that the true intention of Tet was to distract forces from Khe Sanh.

The village of Khe Sanh was the seat of government of Huong Hoa district, an area of Bru Montagnard villages and coffee plantations about 11 km from the Laotian frontier on Route 9, the northernmost transverse road in South Vietnam. The badly-deteriorated Route 9 ran from the coastal region through the western highlands and crossed the border into Laos. The origin of the combat base lay in the construction by US Army Special Forces of an airfield in August 1962 outside the village at an old French fort.The camp then became a Special Forces outpost of the Civilian Irregular Defense Groups, which were to keep watch on PAVN infiltration along the border and to protect the local population.

 

In the winter of 1964, Khe Sanh became the location of a launch site for the highly-classified Military Assistance Command, Vietnam – Studies and Observations Group. The site was first established near the village and later moved to the French fort.From there, reconnaissance teams were launched into Laos to explore and gather intelligence on the PAVN logistical system known as the Ho Chi Minh Trail, also known as Truong Son Strategic Supply Route to the North Vietnamese soldiers.

 

Marino stated that by 1966, Westmoreland had begun to consider Khe Sanh as part of a larger strategy. With a view to gain the eventual approval for an advance through Laos to interdict the Ho Chi Minh Trail, he determined that it was absolutely essential to hold the base.He gave the order for US Marines to take up positions around Khe Sanh. Military Assistance Command, Vietnam, then began planning for incursion into Laos, and in October, the construction of an airfield at Khe Sanh was completed.

The plateau camp was permanently manned by the US Marines in 1967, when they established an outpost next to the airstrip. This base was to serve as the western anchor of Marine Corps forces, which had tactical responsibility for the five northernmost provinces of South Vietnam known as I Corps.The Marines defensive system stretched below the Demilitarized Zone (DMZ) from the coast, along Route 9, to Khe Sanh. In 1966, the regular Special Forces troops had moved off the plateau and built a smaller camp down Route 9 at Lang Vei, about half the distance to the Laotian border.

On 20 January, La Thanh Ton, a PAVN lieutenant from the 325th Division, defected and laid out the plans for an entire series of PAVN attacks.Hills 881 South, 61, nd the main base itself would be simultaneously attacked that same evening. At 00:30 on 21 January, Hill 861 was attacked by about 300 PAVN troops, the Marines, however, were prepared. The PAVN infantry, though bracketed by artillery fire, still managed to penetrate the perimeter of the defenses and were only driven back after severe close-quarters combat.

The main base was then subjected to an intense mortar and rocket barrage. Hundreds of mortar rounds and 122-mm rockets slammed into the base, leveling most of the above-ground structures. One of the first enemy shells set off an explosion in the main ammunition dump.Many of the artillery and mortar rounds stored in the dump were thrown into the air and detonated on impact within the base. Soon after, another shell hit a cache of tear gas, which saturated the entire area.The fighting and shelling on 21 January resulted in 14 marines killed and 43 wounded.Hours after the bombardment ceased, the base was still in danger. At around 10:00, the fire ignited a large quantity of explosives, rocking the base with another series of detonations.

At the same time as the artillery bombardment at KSCB, an attack was launched against Khe Sanh village.The village, 3 km south of the base, was defended by 160 local Bru troops, plus 15 American advisers. At dawn on 21 January, it was attacked by a roughly 300-strong PAVN battalion. A platoon from Company D, 1/26 Marines was sent from the base but was withdrawn in the face of the superior PAVN forces. Reinforcements from the ARVN 256th Regional Force (RF) company were dispatched aboard nine UH-1 helicopters of the 282nd Assault Helicopter Company, but they were landed near the abandoned French fort/former FOB-3 which was occupied by the PAVN who killed many of the RF troops and 4 Americans, including Lieutenant colonel Joseph Seymoe the deputy adviser for Quang Tri Province and forcing the remaining helicopters to abandon the mission. On the morning of 22 January Lownds decided to evacuate the remaining forces in the village with most of the Americans evacuated by helicopter while two advisers led the surviving local forces overland to the combat base.

 

On the night of the fall of Lang Vei, three companies of the PAVN 101D Regiment moved into jump-off positions to attack an outpost west of the Combat Base held by 66 men of Company A, 1st Platoon, 1/9 Marines. At 04.15 on 8 February under cover of fog and a mortar barrage, the PAVN penetrated the perimeter, overrunning most of the position and pushing the remaining 30 defenders into the southwestern portion of the defenses. For some unknown reason, the PAVN troops did not press their advantage and eliminate the pocket, instead throwing a steady stream of grenades at the Marines.At 07.40, a relief force from Company A, 2nd Platoon set out from the main base and attacked through the PAVN, pushing them into supporting tank and artillery fire.By 11.00, the battle was over, Company A had lost 24 dead and 27 wounded, while 150 PAVN bodies were found around the position, which was then abandoned.

 

 

 

On 23 February, KSCB received its worst bombardment of the entire battle. During one 8-hour period, the base was rocked by 1,307 rounds, most of which came from 130-mm (used for the first time on the battlefield) and 152-mm artillery pieces located in Laos. Casualties from the bombardment were 10 killed and 51 wounded. Two days later, US troops detected PAVN trenches running due north to within 25 m of the base perimeter.The majority of these were around the southern and southeastern corners of the perimeter, and formed part of a system that would be developed throughout the end of February and into March until they were ready to be used to launch an attack, providing cover for troops to advance to jumping-off points close to the perimeter.These tactics were reminiscent of those employed against the French at Dien Bien Phu in 1954, particularly in relation to entrenching tactics and artillery placement, and the realization assisted US planners in their targeting decisions.

 

Lownds estimated that the logistical requirements of KSCB were 60 tons per day in mid-January and rose to 185 tons per day when all five battalions were in place. The greatest impediments to the delivery of supplies to the base were the closure of Route 9 and the winter monsoon weather. For most of the battle, low-lying clouds and fog enclosed the area from early morning until around noon, and poor visibility severely hampered aerial resupply.

Making matters worse for the defenders, any aircraft that braved the weather and attempted to land was subject to PAVN antiaircraft fire on its way in for a landing. Once the aircraft touched down, it became the target of any number of PAVN artillery or mortar crews. The aircrew then had to contend with antiaircraft fire on the way out. As a result, 65% of all supplies were delivered by paradrops delivered by C-130 aircraft, mostly by the USAF, whose crews had significantly more experience in airdrop tactics than Marine air crews.The most dramatic supply delivery system used at Khe Sanh was the Low Altitude Parachute Extraction System, in which palletized supplies were pulled out of the cargo bay of a low-flying transport aircraft by means of an attached parachute. The pallet slid to a halt on the airstrip while the aircraft never had to actually land.The USAF delivered 14,356 tons of supplies to Khe Sanh by air (8,120 tons by paradrop). 1st Marine Aircraft Wing records claim that the unit delivered 4,661 tons of cargo into KSCB.

 

By airborne landing near the enemy lines 1^st Battalion 9^th Marines Regiment must relieve the siege of Hills 881 and 861 and then return to Khe Sanh Base to strengthen its defense.

It is March 22nd. The Battle around Khe Sanh Combat Base has been going on for 2 months. The American Headquarters, in order to wash away the shame of its complete surprise, orders a very daring and impressive Secret Operation to take the initiative of the movements back into its own hands. A special contingent of the American Navy Seals with Nasty Boats will penetrate by water to the Capital of Hanoi in the evening and will strike the enemy in his own capital.
