The Battle of Phước Long was a decisive battle of the Vietnam War which began on December 12, 1974, and concluded on January 6, 1975. The battle involved the deployment of North Vietnam's 4th Army Corps for the first time, against determined units of the South Vietnamese Army in Phước Long in Bình Phước Province near the Cambodian border (to be distinguished from the other Phước Long in Bạc Liêu Province, south of Saigon), under the command of Lieutenant General Dư Quốc Đống.[4]

On December 12, 1974, the North Vietnamese 4th Army Corps launched their campaign against Phuoc Long aiming to achieve three key objectives. Firstly, North Vietnamese leaders wanted to test the reaction of the United States Government, to see if they would actually uphold former President Richard Nixon's promises of military retaliation against North Vietnam. Secondly, North Vietnamese field commanders wanted to test the combat readiness of the South Vietnamese Army. And thirdly, the North Vietnamese wanted to solve their logistical problems once and for all, by capturing the district of Phuoc Long and the important transportation routes around it.[5]

The North Vietnamese campaign proved to be a major success, because the fall of Phuoc Long showed that the involvement of the United States in the Vietnam War was truly over, especially when the United States Congress repeatedly voted against additional aid for South Vietnam. Militarily, the victory at Phuoc Long also enabled the North Vietnamese to expand their logistical routes from the Central Highlands of South Vietnam to the Mekong Delta, which placed enormous pressure on the Army of the Republic of Vietnam.[5]

Background[edit]

During the Vietnam War, the district of Phuoc Long played an important role in the defensive posture of the Army of the Republic of Vietnam (ARVN). Phuoc Long is about 120 km north of Saigon; it shared a border with the South Vietnamese districts of Bình Long in the west, Quảng Đức in the east, and Long Khánh District in the south. Phuoc Long also shares an international border with Cambodia. The district of Phuoc Long and the military zones of Bố Đức, Đôn Luân, Đức Phong, the administrative centre of Phuoc Binh, and Bà Rá mountain lies at the centre of South Vietnam’s defensive line in III Corps, which served to defend Saigon and the populous southern provinces.[6]

Route 14, which ran through the district of Phuoc Long and other key military zones, was an important North Vietnamese transportation route which linked the Ho Chi Minh Trail with other Communist-occupied territories in South Vietnam. For that reason, regular units of the South Vietnamese army in Phuoc Long were often placed in a strong position, from which they could disrupt North Vietnamese supply lines. Due to the vulnerability of their supply lines in Phuoc Long and the surrounding areas, North Vietnamese troops at the Viet Cong capital of Loc Ninh and in the Central Highlands, often found themselves isolated from their comrades in the southern provinces of South Vietnam.[6]

Combatants[edit]

North Vietnam[edit]

On July 20, 1974, the High Command of the Vietnam People’s Army created the 4th Army Corps for the purpose of capturing Phuoc Long from the opposing South Vietnamese. Major General Hoang Cam was appointed as the first commander of the 4th Army Corps. The main body of the North Vietnamese 4th Army Corps included the 3rd and 7th Infantry Divisions. The 165th, 201st and 271st Regiments formed the 3rd Infantry Division, while the 2nd, 141st and 209th Regiments formed the 7th Division. In addition, the aforementioned units were supported by the 429th Special Forces Regiment, the 25th Engineers Regiment, the 210th and 235th Logistical Groups and the Viet Cong 9th Division.[1]

The North Vietnamese campaign against Phuoc Long was planned to take place in two separate phases. In the first phase North Vietnamese and Viet Cong forces would capture the military zones surrounding Phuoc Long which included Bu Dang, Bu Na, Bo Duc, Duc Phong, Don Luan, and South Vietnamese firebases around Ba Ra mountain. In the second phase North Vietnamese and Viet Cong units would launch a frontal assault, aimed directly at the district of Phuoc Long, the administrative centre of Phuoc Binh and the strategically important Ba Ra mountain. In both phases of operation, the North Vietnamese army would have to secure Route 14 in order to prevent South Vietnamese reinforcements, which could have come in the form of the ARVN 5th, 25th or 18th Infantry Divisions.[1]

South Vietnam[edit]

South Vietnam’s main defensive assets in and around Phuoc Long included five security battalions and forty-eight platoons of civilian self-defence forces. The defence of Phuoc Long was the responsibility of ARVN Lieutenant General Du Quoc Dong. The 341st and 352nd Security Battalions were tasked with the defence of Don Luan, the 363rd Security Battalion stationed at Bu Na, the 362nd Security Battalion guard the main roads from Vinh Thuan to Bu Dang, and the 340th Security Battalion was placed in reserve at Phuoc Long district. The 341st, 352nd and 363rd Security Battalions all shared the responsibility of protecting Route 14 and the adjoining roads. Firepower support came in the form of one artillery battalion, which was based at the centre of Phuoc Long district, equipped with 150mm and 155mm artillery guns.[7]

Like during the Easter Offensive the strongest units of the South Vietnamese army in III Corps could be deployed to defend Phuoc Long from potential attacks, which included three infantry divisions (5th, 25th and 18th Infantry Divisions) and two armoured units (2nd and 7th Armoured Brigade). In an emergency the ARVN 18th Infantry Division based at Bien Hoa could reach Phuoc Long in the shortest period of time, and the next closest unit was the ARVN 5th Infantry Division based at Ben Cat. In addition, Lieutenant General Du Quoc Dong could have access to the 81st Airborne Ranger Battalion and more than one hundred helicopters, mainly UH-1 Huey and CH-47 Chinook models. While air support could come in the form of fighter-bombers from the 3rd and 5th Air Divisions of the South Vietnamese air force, based at Tan Son Nhat and Bien Hoa.[7]

Prelude[edit]

The North Vietnamese military opened its campaign against Phuoc Long on December 12, 1974, using the 4th Battalion of the 165th Infantry Regiment to attack a South Vietnamese outpost located on Route 14, which was defended by a single South Vietnamese security company. On the same night the military zone of Bù Đốp was also attacked by a company of Viet Cong special forces from the Phuoc Binh area. During the next few days the South Vietnamese army managed to recapture its positions along Route 14, but they could not clear the main road. On December 13 ARVN Colonel Nguyen Thong Thanh inspected the Route 14 area, and decided to raise the level of alertness from code ‘yellow’ to ‘orange’ for all South Vietnamese installations in the area. Due to the heavy rain which flooded the main roads leading to Phuoc Long, the North Vietnamese decided to postpone further attacks which were planned to take place on December 13.[8]

On December 14, the under strength 271st Regiment of the North Vietnamese 302nd Division launched their attack on the ARVN 362nd Security Battalion, also based in Bù Đốp. After two hours of fighting nearly all members of the 2/271st Regiment had sustained injuries, but the 271st Regiment managed to penetrate the South Vietnamese defensive line around Bu Dop, and by 11.30am the 271st Regiment successfully overwhelmed the Bu Dop military zone.[9] On the same day, after a night of encirclement, the North Vietnamese 165th and 201st Regiments, both drawn from the 7th Infantry Division, began asserting their authority over the Vinh Thien area and the Bu Dang administrative centre after more than two hours of fighting.[8]

On December 15, soldiers from the North Vietnamese 429th Special Forces Regiment attacked Bu Na, which was defended by one South Vietnamese company from the 363rd Security Battalion, and an artillery platoon. The 363rd Security Battalion, with strong support from South Vietnamese air force fighter-bombers based at Bien Hoa, fought back fiercely in their attempt to defend Bu Na. However, by the end of the day South Vietnamese defenders around Bu Na gave up, when reinforcements from Phuoc Long failed to arrive due to the closure of Route 14 by the North Vietnamese army. On December 16, Lieutenant General Du Quoc Dong flew out to Phuoc Long to assess the situation around the area, and to bolster the defences of Phuoc Long with the 2/7th Regiment, from the ARVN 5th Infantry Division. On the same day, South Vietnamese Colonel Do Cong Thanh also organised a number of counter-attacks against North Vietnamese positions around Route 14, which connects with the Bu Dang area, but on each on occasion they were pushed back by local Viet Cong units who were guarding the area.[7]

Several days later on December 22, the South Vietnamese 341st Security Battalion at Bố Đức was attacked for the second time by the North Vietnamese 165th Regiment. Subsequently, South Vietnamese units at Phước Tín, Phước Quả, and Phước Lộc were also overwhelmed by the North Vietnamese. The South Vietnamese army attempted to stage a counter-attack on Bo Duc, but they were easily defeated by the North Vietnamese 6/165th Regiment, as a result all surviving South Vietnamese units retreated back to the Ba Ra area to lick their wounds.[10] Two days later General Dư Quốc Đống tried to reinforce Phuoc Long with a regiment from the ARVN 18th Infantry Division, but President Nguyen Van Thieu overturned General Dong’s decision on the basis that all deployments at the regimental-level must be made by Thieu himself. As a result, Lieutenant General Dư Quốc Đống had to order Brigadier General Lê Nguyên Vĩ to reinforce the areas around Đồng Xoài with units taken from the ARVN 5th Infantry Division. However, by the time regular units of the South Vietnamese army arrived at their destination, the North Vietnamese had already encircled the Don Luan military zone, so it was within range of the formidable North Vietnamese long-range artillery guns. Even though the South Vietnamese received extensive air support they could only sent one company into Đồng Xoài, so Brigadier General Le Nguyen Vi was forced to withdraw his forces from the area.[7]

At 5.37am on December 26, 1974, the North Vietnamese 141st Regiment opened their attack on the South Vietnamese base at Don Luan from four different directions, after 15 minutes of artillery bombardment from supporting artillery units. Due to the strong presence of North Vietnamese artillery, South Vietnamese artillery units at Don Luan were simply overwhelmed. In addition, the high calibre anti-aircraft guns used by the North Vietnamese 20th Air-Defence Battalion also limited the effectiveness of the A-1 Skyraider and the A-37 Dragonfly, used by the South Vietnamese air force to support the ground troops. At 10.30am all South Vietnamese units at Đôn Luân capitulated and Major Đặng Vũ Khoái, commander of the 352nd Security Battalion, was captured at Suoi Rat along with his junior officers. Towards the end of the day, the North Vietnamese 141st Regiment also captured other South Vietnamese installations at Ta Be, Phước Thiền, and a helicopter base.[1]

In just two weeks the North Vietnamese army had managed to punch several holes in the defensive line of South Vietnam’s III Corps, with the capture of Bù Đốp, Bù Na, Bù Đăng and Đôn Luân. For the Army of the Republic of Vietnam (ARVN), the lost of four important outposts in III Corps was a severe blow, especially with opposing North Vietnamese and Viet Cong forces controlling all main roads leading to the district of Phuoc Long such as Route 14, Route 7, and the provincial roads 1 and 2. The South Vietnamese army, based at the administrative centre of Phuoc Binh and Phuoc Long, suddenly found themselves surrounded by the strong and well-equipped North Vietnamese 4th Army Corps.[7]

Fall of Phuoc Long[edit]

To halt the North Vietnamese onslaught at Phuoc Long, Lieutenant General Du Quoc Dong need at least one infantry division and one unit of armoured cavalry, however South Vietnamese infantry divisions based in I Corps were not allowed to be deployed without the approval of South Vietnamese President Nguyen Van Thieu. On December 29, realising that the district of Phuoc Long was in serious danger of being overrun, General Cao Van Vien asked President Nguyen Van Thieu to approve a plan to defend Phuoc Long that hed been prepared back in October 1974. Shortly afterwards General Cao Van Vien received a message from President Nguyen Van Thieu which advised Lieutenant General Du Quoc Dong not to make discretionary decisions, and to try to maintain the morale of the South Vietnamese soldiers at Phuoc Long.[7]

While ARVN Lieutenant General Du Quoc Dong was desperate to find additional reinforcements, the North Vietnamese were making their way towards Phuoc Long and Phuoc Binh between December 27 and December 30, 1974. On the afternoon of December 30, North Vietnamese army units took up their positions in the following order: the 165th Regiment was positioned on the south and south-eastern areas of Phuoc Binh, the 141st Regiment was positioned along provincial road no. 2 in the north and northwest leading towards Phuoc Binh, the 271st Regiment blocked Route 309, the 16th Regiment moved from Tay Ninh to the north of Song Be, the 78th Special Forces Battalion gathered near the foot of Ba Ra mountain, while the 2nd and 209th Regiments were placed in reserve. In addition to the units above, the North Vietnamese 4th Army Corps was strengthened with one artillery company equipped with 130 mm artillery guns, and two armoured companies with 14 T-54 tanks.[1]

On December 31, 1974, as Lieutenant General Du Quoc Dong received President Thieu’s message, the North Vietnamese began their final assault on the district of Phuoc Long with the 165th Regiment, the 141st Regiment, the 3rd Battalion and several local Viet Cong units leading the attack. However, due to the slow deployment of the 78th Special Forces Battalion and the 271st Regiment, South Vietnamese artillery guns at Phuoc Long were able to respond to initial North Vietnamese assaults, by pounding North Vietnamese positions around Ba Ra mountain. Furthermore, the ARVN 1/7th Regiment, 5th Infantry Division, also attacked the North Vietnamese 5th and 6th Battalions, both belonging to the 165th Regiment, at the foot of Ba Ra mountain. As a result, the 141st Regiment had to attack the administrative centre of Phuoc Binh by itself, while 165th Regiment was forced to stop in order to deal with the South Vietnamese counter-attack. At 1 pm on December 31, North Vietnamese Major General Hoang Cam sent four T-54 tanks to support the 141st Regiment, but one of the tanks was put out of action when it hit a landmine. The 141st Regiment, with three remaining T-54 tanks in support, were able to force their way into the centre of Phuoc Binh and capture the local airfield. By 3 pm, the administrative centre of Phuoc Binh had fallen, and the ARVN 2/7th Regiment was pushed back towards Soui Dung.[11]

Meanwhile on the evening of December 31, the South Vietnamese air force had flown more than 50 bombing sorties against North Vietnamese positions at the foot of Ba Ra mountain, temporarily stopping attacks from the North Vietnamese 78th Special Forces Battalion. The North Vietnamese responded to South Vietnamese air attacks by rolling out their long-range anti-aircraft guns, which stopped South Vietnamese pilots from hitting North Vietnamese positions until the next day, and allowing the 78th Special Forces Battalion to capture Ba Ra mountain. The capture of Ba Ra mountain enabled North Vietnamese army units to occupy the high ground areas surrounding Phuoc Long, where they could direct artillery fire against South Vietnamese positions.[10] Throughout the day on January 1, 1975, the South Vietnamese air force conducted a further 53 bombing sorties, again temporarily delaying the North Vietnamese attack on Phuoc Long. By the end of the day, South Vietnamese pilots claimed to have set ablaze 15 North Vietnamese tanks. On the other side, the South Vietnamese army lost eight 105 mm and four 155 mm artillery guns during the initial North Vietnamese assault on Phuoc Binh. And, by the early hours of January 2, 1975, all of Phuoc Long was within range of North Vietnamese artillery.[10]

Realising that the South Vietnamese defenders were in danger of being destroyed, ARVN Colonel Do Cong Thanh quickly reorganised all his units. Subsequently, the headquarters of Phuoc Long district was moved to Camp Le Loi, the 340th Security Battalion had to defend the bridges at Suoi Dung, and the 2/7th Regiment took up their positions along the main streets of Tu Hien 1 and Tu Hien 2.[6] As a result, the South Vietnamese were able to put up fierce resistance, thus delaying the advancing North Vietnamese army for another 24 hours. On the morning of January 2, 1975, North Vietnamese artillery bombarded South Vietnamese positions in Phuoc Long for about an hour, to pave the way for further assaults from the 141st, 165th and 271st Regiments. In the south of Phuoc Long, the 165th Regiment successfully captured the South Vietnamese camp of Doan Van Kieu, in the west the 141st Regiment clashed with the ARVN 1/9th Regiment at Ho Long Thuy, and in the southeast the 271st Regiment were able to secure Tu Hien 1 and Tu Hien 2.[10]

On the morning of January 3, elements of the 141st Regiment made their way into the district of Phuoc Long, only to find the town isolated. The North Vietnamese 4th Army Corps then decided to bolster the strength of the 141st Regiment, with one battalion taken from the 201st Regiment. To deal with the North Vietnamese, Lieutenant General Do Quoc Dong attempted to land the 8/5th Infantry Division in the district of Phuoc Long using helicopters, but fierce anti-aircraft fire from the North Vietnamese 210th Air-Defence Regiment forced South Vietnamese helicopters to turn around. At the same time, South Vietnamese air force transport planes also tried to drop ammunition supplies for South Vietnamese soldiers in the northern areas of Phuoc Long, but the ammunition load landed in the wrong place and was captured by North Vietnamese soldiers. Due to the heavy artillery barrage, the South Vietnamese headquarters at Phuoc Long was heavily damaged with the district’s deputy commander dead of his wounds, while the commander of Phuoc Binh suffered severe injuries.[11]

On the morning of January 4, the South Vietnamese air force resumed their attacks on North Vietnamese columns, forcing North Vietnamese units to slow their attacks. In his last-ditch effort to save Phuoc Long, Lieutenant General Du Quoc Dong ordered the 81st Airborne Ranger Battalion to be airlifted into action. But as soon as the first group of the 81st Airborne Ranger Battalion landed on Dac Song, they were quickly decimated by North Vietnamese artillery, with the unit suffering losses equivalent to two companies. The North Vietnamese 4th Army Corps command immediately responded by ordering the 16th Regiment to secure Dac Song and the nearby bridge at Dac Lung, pursuing the surviving elements of the 81st Airborne Ranger Battalion. However, by that stage South Vietnamese defence lines in Phuoc Long had narrowed, leaving only the administrative centre and the local markets still under South Vietnamese control, while most of the town had fallen to the North Vietnamese army.[1]

On January 5, the North Vietnamese 165th and 201st Regiments continued their encirclement of the Phuoc Long administrative centre, as well as shelling key targets in the area. On the following day, the North Vietnamese 4th Army Corps command sent the 201st Regiment, along with ten additional tanks, to reinforce the units already fighting in Phuoc Long. And to cut off the South Vietnamese route of escape, Cach Mang and Dinh Tien Hoang streets were blocked. At 8 pm on January 6, the last South Vietnamese defensive post, occupied by the surviving elements of the 81st Airborne Ranger Battalion, was captured by the North Vietnamese. During the night a small number of South Vietnamese soldiers who had survived the battle were evacuated from Phuoc Long. At the battle’s conclusion, the North Vietnamese claimed they had captured 2,444 prisoners, including 26 officers, 5,000 small arms of various kinds and more than 100,000 rounds of ammunition.[6]

Aftermath[edit]

Military Effect[edit]

The South Vietnamese army in Phuoc Long, under the command of Lieutenant General Du Quoc Dong, used everything they had at their disposal in order to stop the North Vietnamese onslaught. In their efforts to save Phuoc Long and other territories around the district, the South Vietnamese lost more than a thousand soldiers killed in action and 2,444 others were captured. The sacrifice of South Vietnamese soldiers in the battle was exemplified by the 250-men 81st Airborne Ranger Battalion, which lost more than 150 soldiers in their last-ditch effort to save Phuoc Long. In the end, about 850 South Vietnamese soldiers were evacuated from the battlefield.[3]

In comparison to their South Vietnamese counterparts, the casualties suffered by the North Vietnamese 4th Army Corps were relatively light with about 1,300 killed or wounded. In logistical terms the victory at Phuoc Long enabled the North Vietnamese to connect their supply lines from the Ho Chi Minh Trail, with bases in the Central Highlands and the Mekong Delta. At the same time, with a strengthened supply line which stretched from the north to the southern provinces of South Vietnam, regular units of the North Vietnamese army were able to apply additional pressure on the weakened South Vietnamese army already starved of American supplies.[2]

Political Effect[edit]

In Hanoi, the capture of Phuoc Long by the 4th Army Corps provided the Communist leadership with clear answers about America’s commitment to defend South Vietnam, as well as their willingness to re-enter the conflict. The Battle of Phuoc Long not only gave North Vietnamese political and military planners a greater awareness of South Vietnam’s dire military situation, but it also showed that the United States government were no longer interested in the survival of the Saigon regime. Thus, the optimism and confidence of North Vietnamese leaders were significantly strengthened, because they could finally destroy the Saigon regime and win the war once and for all. The lessons learned at Phuoc Long were put into practice during the 1975 Spring Offensive, which ultimately led to the political and military capitulation of South Vietnam on April 30, 1975.[6]

In Saigon, South Vietnamese political and military establishments did not share the same level of confidence and optimism, because the loss of Phuoc Long in III Corps exposed the severe weaknesses of the Army of the Republic of Vietnam. For General Cao Van Vien, Chief of the Army of the Republic of Vietnam, the military situation was clear: if South Vietnamese units could not hold their own against a single attack, there was no way they could ever stop a large-scale invasion.[6] To make matters worst, the United States Congress repeatedly voted against President Gerald Ford’s request to give additional aid for South Vietnam. On January 10, 1975, President Nguyen Van Thieu called on the people of South Vietnam to pray for Phuoc Long, as well as renew their determination to retake the district. One month later, Thieu reinforced his previous message by asking the people of South Vietnam to maximise their support of soldiers on the frontline, stabilise the country’s internal situation, and increase economic production.[6]
