Thailand announces plans to withdraw its 12,000-man contingent from South Vietnam. Thai forces went to Vietnam as part of the Free World Military Forces, an effort by President Lyndon B. Johnson to enlist allies for the United States and South Vietnam. By securing support from other nations, Johnson hoped to build an international consensus behind his policies in Vietnam.
The first Thai contribution to the South Vietnamese war effort came in September 1964, when a 16-man Royal Thai Air Force group arrived in Saigon to assist in flying and maintaining some of the cargo aircraft operated by the South Vietnamese Air Force. In 1966, in response to further urging from President Johnson, the Thais agreed to increase their support to South Vietnam. The Royal Thai Military Assistance Group was formed in Saigon in February 1966. Later that year, the Thai government, once again at Johnson’s insistence, agreed to send combat troops to aid the South Vietnamese government. In September 1967, the first elements of the Royal Thai Volunteer Regiment, the “Queen’s Cobras,” arrived in Vietnam and were stationed in Bear Cat (near Bien Hoa, north of Saigon). The Thai regiment began combat operations in October 1967.
In July 1968, the Queen’s Cobras were replaced by the Royal Thai Army Expeditionary Division (the “Black Panthers”), which included two brigades of infantry, three battalions of 105-mm field artillery, and an armored cavalry unit. In August 1970, the Black Panther Division was renamed the Royal Thai Army Volunteer Force, a title it retained throughout the rest of its time in South Vietnam.
The decision by the Thai government to begin withdrawing its troops was in line with President Nixon’s plan to withdraw U.S. troops from South Vietnam as the war was turned over to the South Vietnamese. The first Thai troops departed South Vietnam in 1971 and all were gone by early 1972.
