1950 US Military Assistance Advisory Group arrives in Saigon A US Military Assistance Advisory Group (MAAG) of 35 men arrives in Saigon to screen French requests for American military aid, assist in the training of South Vietnamese troops, and advise on strategy. President Harry Truman had approved National Security Council (NSC) Memorandum 64 in March 1950, proclaiming that French Indochina (Vietnam, Cambodia, and Laos) was a key area that could not be allowed to fall to the communists and that the United States would provide support against communist aggression in the area. However, NSC 64 did not identify who would receive the aid, the French or the South Vietnamese. The French did not want the aid to go directly to the South Vietnamese and opposed the presence of any American advisory group. Nevertheless, the US government argued that such a team would be necessary to coordinate requisitioning, procurement, and dissemination of supplies and equipment. Accordingly, an advisory group was dispatched to Saigon. In the long run, however, the French high command ignored the MAAG in formulating strategy, denied them any role in training the Vietnamese, and refused to keep them informed of current operations and future plans. By 1952, the United States would bear roughly one-third of the cost of the war the French were fighting, but find itself with very little influence over French military policy in Southeast Asia or the way the war was waged. Ultimately, the French would be defeated at the battle of Dien Bien Phu and withdraw from Vietnam, passing the torch to the United States. In 1964, MAAG Vietnam would be disbanded and its advisory mission and functions integrated into the US Military Assistance Command Vietnam (MACV), which had been established in February 1962.
