Lang Vay Strongpoint – Witness to the Major Military Event of 1968

Lang Vay Strongpoint is located on a basalt red soil hill cluster in Tan Long commune (now bordering Tan Lap commune), Huong Hoa district, Quang Tri province. It is situated about 1 km south of National Route 9 (km 75), and about 8-15 km southwest of the Ta Con (Khe Sanh) strongpoint cluster. This was an important outpost blocking the western gateway of the Route 9 - Khe Sanh defense system. The US built Lang Vay on two high points, 320 and 230, measuring about 600m in length and 200m in width. The stronghold was reinforced by a system of fortified bunkers and trenches, multi-layered barbed wire fences, dense minefields, and powerful artillery positions (106.7mm, 81mm mortars...).

The defending force included Montagnard CIDG (Civilian Irregular Defense Group) forces, US advisors, and several other units. Prior to the 1968 battle, about 520 Royal Lao soldiers retreated here from Huoi San, bringing the total troop strength to around 900. The weaponry was heavily armed with hundreds of Claymore mines, M72 LAW anti-tank weapons, and various mortars and heavy machine guns. Lang Vay was not only a military strongpoint but also a 'chokepoint' blocking troop movement routes from Laos into the South, contributing to the defense of Khe Sanh – the US strategic 'anchor' in northwestern Quang Tri.

Before 1968, the US developed Khe Sanh into the strongest base complex in South Vietnam to intercept the Ho Chi Minh Trail and protect the border. The Route 9 - Khe Sanh Campaign began in January 1968, with opening attacks such as those on Huong Hoa district headquarters (Jan 20), Huoi San (Jan 24), and Cam Lo. At that time, Lang Vay was a fortified stronghold with 4 commando companies, 1 US platoon, and about 520 retreating Royal Lao troops, totaling around 900 personnel. This was a key target for the Liberation Army to create a diversion and draw in US forces.

The battle began at 17:00 on February 6, 1968, when the Liberation Army's artillery simultaneously bombarded the strongpoint. PT-76 tank No. 268 led the way, coordinating with infantry from Regiment 24 (Division 304) to breach the wire fences. Fierce fighting continued through the night, as the enemy resisted from bunkers and underground shelters. By 11:00 AM on February 7, the Liberation Army gained complete control, eliminating 316 enemy troops, capturing 253 alive, and seizing numerous weapons. This was the first combined arms operation involving tanks on the Southern battlefield.

The assault began with a heavy artillery barrage on the strongpoint. Next, infantry and commando prongs supported by tanks charged forward simultaneously. The appearance of the "steel fists" — the PT-76 tanks — took the enemy completely by surprise. With their obstacle-crossing capabilities and formidable firepower, the tanks quickly broke through layers of barbed wire and fortified structures, clearing the path for infantry to eliminate enemy forces inside underground shelters and bunkers. Tank No. 268 performed outstandingly by leading the spearhead, bravely pressing through enemy fire, knocking down the main gate, and supporting the infantry in taking control of the enemy headquarters.

After hours of fierce combat, by the morning of February 7, 1968, Lang Vay Strongpoint fell completely. The Liberation Army eliminated and captured the majority of the enemy forces here, seizing large quantities of weapons and war materials.

The victory at Lang Vay Strongpoint in 1968 carried immensely important significance:

• Affirming a development step in military art: This was the first large-scale combined arms battle involving tanks, proving that the organization and combat coordination capabilities of the Liberation Army had reached a new height, capable of breaching modern and fortified enemy defense positions.
• Breaking the "shield" Western Khe Sanh: The destruction of Lang Vay Strongpoint significantly weakened the outer defensive line of Khe Sanh Base, leaving the center threatened and increasingly isolated. This contributed to creating a major advantage for the Liberation Army in besieging and controlling the Route 9 - Khe Sanh battlefield afterwards.
• A heavy blow to enemy morale: The victory at Lang Vay caused shockwaves throughout the US military and the Saigon administration, especially with the loss of a strongpoint previously considered impregnable. It demonstrated the failure of a defensive strategy relying solely on fortified fortifications and firepower superiority.
• Enhancing the status and prestige of the Liberation Army: This victory demonstrated the effective and bold operational capabilities of the Liberation Army in a complex terrain, contributing to strengthening confidence in ultimate victory.

Combining these significance points makes the victory at Lang Vay Strongpoint an eloquent testament to the remarkable development of the Liberation Army's military art, as well as a powerful blow to the US aggressive will, contributing significantly to the overall status of the 1968 Tet Offensive.

Today, the Lang Vay historical site still preserves a victory memorial monument, PT-76 tank No. 268 (permanently displayed), a system of trenches, concrete bunkers, and old fences. The site, measuring about 600m long and 200m wide across high points 320 and 230, allows visitors to visualize the battlefield of the past.

During your visit, you can explore the trenches, take photos beside the historic tank, and listen to guides recount the battle.
