The Army General Staff Plot was a failed 1948 attempt to overthrow the Thai government of Field Marshal Plaek Phibunsongkhram. The plotters were members of the army general staff, among whom were Lieutenant-General Chit Mansin Sinatyotharak, Pridi's former supreme commander, and Major General Net Khemayothin, a close associate of Phibun during the war and later a prominent Seri Thai member. They objected to the army's increasingly corrupt and inefficient leadership, and hoped to reorganise and professionalise the military. Their plan called for the arrest of Phibun, top government officials, and leading army officers during a birthday party for Sarit Thanarat scheduled for 1 October 1948.
