Phu Bai Combat Base (also known as Phu Bai Airfield and Camp Hochmuth) is a former U.S. Army and U.S. Marine Corps base south of Huế, in central Vietnam.
The Army Security Agency, operating under cover of the 3rd Radio Research Unit (3rd RRU), established a radio facility at Phu Bai in 1963, 12 km southeast of Huế on Highway 1. [1] The operational unit was later redesignated as the 8th Radio Research Field Station (8th RRFS).
On 10 April 1965 Task Force Alpha of 2nd Battalion, 3rd Marines was landed by helicopter from Da Nang Air Base to secure the area. On 13 April a detachment of ten UH-34D helicopters from HMM-162 was established at Phu Bai. On 14 April Battalion Landing Team 3rd Battalion, 4th Marines replaced Task Force Alpha at Phu Bai.

In late 1965, The 3rd Marine Division established its headquarters at Phu Bai and would remain there until late 1967, when it was moved forward to Đông Hà.
On 30 August 1967 a People's Army of Vietnam mortar attack on the base damaged 13 helicopters, killing two Seabees and wounding 32 Marines and Seabees. [3]
In late November 1967, the base was named Camp Hochmuth in honor of Bruno Hochmuth, Commanding General, 3rd Marine Division, who was killed in a helicopter explosion north of Huế.
In June or July 1968, U.S. Special Forces established Forward Operating Base 1 (FOB 1) at Phu Bai. The base remained in use until early 1969. [4]
Marine units based at Phu Bai during this period included:
On 30/31 January 1968, the base was hit by Vietcong mortar and rocket fire as part of the Tet Offensive. The base was used to support U.S. and ARVN forces fighting in the Battle of Huế. The first relief force was dispatched from Phu Bai to the MACV Compound in Huế City. [8] : 9
On 15 February 1968, General Creighton Abrams established MACV forward at Phu Bai to assume direct control of US forces in northern I Corps, which were then engaged in the Battle of Huế, the Battle of Khe Sanh, and the Tet Counteroffensive. [8] : 140 [9]
On 10 March 1968, MACV Forward, having served its purpose, was converted to a Corps headquarters and designated Provisional Corps, Vietnam, under the command of Lieutenant General William B. Rosson. Rosson exercised operational control over the 3rd Marine Division (Reinforced), the 1st Cavalry Division, the 101st Airborne Division (Reinforced) and assigned Corps troops. The new Corps also co-operated closely with the ARVN 1st Division in the area. Provisional Corps, Vietnam, was designated XXIV Corps on 12 August 1968. [10]
The 45th Engineer Group moved north to the Phu Bai area in February 1968, where it assumed general construction support missions for the I Corps Tactical Zone. The group then remained in the Da Nang area until departing Vietnam. [11]
In 1969, the 85th Evacuation Hospital moved from Qui Nhơn and was established at the northwest end of the airfield, adjacent to Highway 1. [1]
In late 1969, the 101st Administration Company (101st Airborne Division) was moved from Bien Hoa Base Camp to Phu Bai.
Units based at Phu Bai during this period included:
On 20 October 1972 the base was handed over to the South Vietnamese. [12]
The ARVN operated Phu Bai as a forward logistics base, and it was the only airport serving Huế.
In September 1974, during the Battle of Phú Lộc, after pushing the ARVN defenders off Mo Tau Mountain, the People's Army of Vietnam (PAVN) targeted artillery fire against the base until they were evicted by the ARVN 1st Division and 15th Ranger Group on 11 December. [13]
From 5 March 1975, the PAVN shelled the base as part of the Hue–Da Nang Campaign. Nonetheless, the base continued to be used for aerial reinforcement of the ARVN, until it was overrun by the PAVN on 23/24 March 1975.

The Battle of Huế, was a major battle in the Tết Offensive launched by North Vietnam and the Việt Cộng during the Vietnam War. Initially losing control of most of Huế and its surroundings, the combined forces of South Vietnam and the United States gradually recaptured the city after a little over one month of intense fighting. The battle was one of the longest and bloodiest of the war, causing it to negatively affect the American public perception of the war. The battle is widely considered to be one of the toughest and most intense urban battles ever fought.

Initially trained as a counter-insurgency light infantry force by removing the fourth company each of the existing infantry battalions, they later expanded into a swing force capable of conventional as well as counter-insurgency operations, and were relied on to retake captured regions. Later during Vietnamization the Civilian Irregular Defense Group program was transferred from MACV and integrated as Border Battalions responsible for manning remote outposts in the Central Highlands.

The Vietnamese Airborne Division began as companies organized in 1948, prior to any agreement over armed forces in Vietnam. After the partition of Vietnam, it became a part of the Army of the Republic of Vietnam. This division had its distinct origins in French-trained paratrooper battalions, with predecessor battalions participating in major battles including Dien Bien Phu and retained distinct uniforms and regalia. With the formation of an independent republic, the colonial paratroopers were dissolved, however regalia and aesthetics alongside the nickname "Bawouans" would be retained.

After being put on the defensive in the city of Quảng Trị, the Allied forces regrouped and forced the PAVN/VC out of the town after a day of fighting.
