In mid-1954, General Nguyễn Văn Hinh, the head of the State of Vietnam's VNA, announced that he did not respect the leadership of Prime Minister Diệm, and vowed to overthrow him. The "coup" never materialised and Hinh was forced into exile, but not before appointing Ba Cụt to the rank of colonel in the VNA in an attempt to undermine Diệm, as the Hòa Hảo warlord was openly contemptuous of the prime minister. In August, Ba Cụt and his 3,000 men broke from the VNA and left their Thốt Nốt base for the jungle, and fought against those who had briefly been their comrades; this put him at odds with most Hòa Hảo leaders, who accepted government payments to integrate their forces into the VNA. Operation Ecaille, the initial military offensive by the VNA against Ba Cụt was a failure, possibly because the details of the planned attack on his forces were leaked to him by Soái, a Hòa Hảo member of the National Defence Committee.
