Battle of Phước Long

The Battle of Phước Long was a decisive battle of the Vietnam War which began on 12 December 1974, and concluded on 6 January 1975. The battle involved the deployment of the People's Army of Vietnam (PAVN) 4th Army Corps for the first time, against units of the Army of the Republic of Vietnam (ARVN) 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.

On 12 December 1974, the PAVN 4th Army Corps launched their campaign against Phước 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, PAVN field commanders wanted to test the combat readiness of the ARVN; and thirdly, the North Vietnamese wanted to solve their logistical problems once and for all, by capturing the district of Phước Long and the important transportation routes around it.

The PAVN campaign proved to be a major success, because the fall of Phước 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 Phước Long also enabled the North Vietnamese to expand their logistical routes from the Central Highlands to the Mekong Delta, which placed enormous pressure on the South Vietnamese military.
