It took three years for Minh Mạng to quell the rebellion and the Siamese offensive. When the fortress of Phien An was invaded in September 1835, 1,831 people were executed and buried in mass graves (now situated in District 3, Saigon). Only six survivors were temporarily spared, among whom were Le Van Cu, but also the French missionary Father Joseph Marchand, of the Paris Foreign Missions Society. Marchand had apparently been supporting the cause of Lê Văn Khôi, and asked for the help of the Siamese army, through communications to his counterpart in Siam, Father Taberd. This revealed the strong Catholic involvement in the revolt. Father Marchand was tortured and executed on 5 November 1835, as was the child Le Van Cu.
