First Indochina War

Among the first divisions raised, the 324th Division participated in the Battle of Hòa Bình. Alongside the 320th Division and other units, this division had participated in laying ambushes on armoured and relief convoys intending to lift the siege of Dien Bien Phu alongside the battle itself.[1]

Vietnam War

Starting in 1955, the 90th Regiment, 324th Division began operating in Cambodia and training cadres and battalions from ethnic Khmer and Central Highlands groups.[2] These groups were to be trained as the nucleus for future revolutionary activities, in particular in securing the routes along the Ho Chi Minh Trail.[2] In 1961, the Division was placed in Xépôn and along Route 9, on the Ho Chi Minh Trail.

1966-7

In response to increasing U.S. airstrikes, the Division was deployed increasingly southwards alongside artillery regiments attached to it to harass U.S. forces in northern Quảng Trị Province.[3]

In April 1966 U.S. intelligence reported that the Division was digging in north of the Vietnamese Demilitarized Zone (DMZ).[4]:17 On the morning of 19 May, units from the 324B attacked isolated Army of the Republic of Vietnam (ARVN) outposts at Con Thien and Gio Linh south of the DMZ.[4]:39 On 6 July two soldiers from 812th Regiment of the Division were captured by Marines near the Rockpile, they revealed that their mission was to liberate Quảng Trị Province.[4]:17 In response to this, the Marines launched Operation Hastings which ran from 15 July to 3 August 1966. Losses among the Division amounted to 824 killed and 17 captured.[5]:159–75

On the early morning of 26 August the Division's 812th Regiment attacked Cam Lộ Combat Base killing nine Marines.[5]:186–7

At 04:00 on 8 May 1967 following an hour-long mortar and artillery barrage, the 4th and 6th Battalions of the 812th Regiment attacked the Marine base at Con Thien By 09:00 the Marines had repulsed the attack and the 812th Regiment withdrew leaving 197 dead and eight prisoners.[4]:65–73 On 14 May during Operation Prairie IV, the 1st Battalion 9th Marines (1/9 Marines) clearing Route 561 from Cam Lo to Con Thien were ambushed by the 6th Battalion, 812th Regiment, 28 Marines were killed for the loss of 134 PAVN.[4]:78–81

On 2 July the Marines launched Operation Buffalo, a sweep of the area north of Con Thien. As the 1/9 Marines moved along Route 561 in an area called the Marketplace, the 90th Regiment attacked the Marines inflicting severe casualties on Company B. This was the single worst day for Marines in Vietnam with 84 killed. Operation Buffalo concluded on 14 July at a cost of 159 Marines killed, while the 90th Regiment suffered 1,290 killed.[4]:112–25

On 16 July the Marines launched Operation Kingfisher in the western part of Leatherneck Square with the 324th also participating. The operation concluded on 31 October, in a series of skirmishes and ambushes the Division had lost 1,117 killed and five captured while 340 Marines were killed.[6]

In early November 1967, an Arc Light strike hit the headquarters of the 812th Regiment 3 miles (4.8 km) southwest of Con Thien.[4]:277–8

On 1 November 1967, the Marines launched Operation Kentucky as part of the continuing operations to secure the DMZ around Con Thien. The operation concluded on 28 February 1969, and the Division and 320th Division lost a total of 3,839 killed and 117 captured while the Marines lost 520 killed.[7]

By 19 March the Division's 29th and 803rd Regiments Regiment were attacking the South Vietnamese 147th Marine Brigade operating around Fire Support Base Delta (16.550°N 106.539°E / 16.550; 106.539) while its 812th Regiment attacked the 258th Marine Brigade at Fire Support Base Hotel in an attempt to prevent ARVN withdrawal along Route 9.[9]:113 At dawn on 21 March the 29th and 803rd Regiments attacked FSB Delta, the Marines held on supported by artillery fire and airstrikes including B-52 strikes which a prisoner later reported had killed 400 PAVN soldiers. The Marines lost 85 killed, while the Division lost 600 killed, five captured and 200 individual and 60 crew-served weapons captured.[9]:116 On the afternoon of 22 March the Division resumed its attack on FSB Delta supported by 10 tanks, the Marines destroyed the first two with M72 LAWs, mines destroyed a third and an airstrike destroyed the fourth but the remainder pressed the attack and the Marine Brigade withdrew towards Fire Support Base Hotel but were ambushed en route. By the morning of 23 March the 147th Marine Brigade had regrouped at FSB Hotel and were evacuated into South Vietnam having lost 37 killed or missing, total losses for the Division were estimated as being 2,000 killed or wounded.[9]:119–20
