1965 South Vietnamese coup
On February 19, 1965, some units of the Army of the Republic of Vietnam commanded by General Lâm Văn Phát and Colonel Phạm Ngọc Thảo launched a coup against General Nguyễn Khánh, the head of South Vietnam's ruling military junta. Their aim was to install General Trần Thiện Khiêm, a Khánh rival who had been sent to Washington D.C. as Ambassador to the United States to prevent him from seizing power. The attempted coup reached a stalemate, and although the trio did not take power, a group of officers led by General Nguyễn Chánh Thi and Air Marshal Nguyễn Cao Kỳ, and hostile to both the plot and to Khánh himself, were able to force a leadership change and take control themselves with the support of American officials, who had lost confidence in Khánh.
Maxwell Taylor, the US Ambassador to South Vietnam, was an opponent of Khánh and encouraged the other South Vietnamese officers to launch a coup.

Tan Son Nhut Air Base, pictured here in 1962, was the headquarters of both the US and South Vietnamese military and a key target in any coup.
William Westmoreland, the US commander in Vietnam, tried to organize some forces to stop the coup and overthrow the incumbent Khánh.
Lâm Văn Phát was a Major general in the South Vietnamese Army of the Republic of Vietnam (ARVN). He is best known for leading two coup attempts against General Nguyễn Khánh in September 1964 and February 1965. Although both failed to result in his taking power, the latter caused enough instability that it forced Khánh to resign and go into exile.
Air Force Chief Kỳ was one of the leading figures in putting down Phát's coup attempt.
