Đôn was appointed as the acting Chief of the Armed Forces in the place of General Lê Văn Tỵ, who was abroad having medical treatment. Đôn noted that Diệm was apparently concerned with the welfare of the monks, telling the generals that he did not want any of them hurt. The martial law orders were authorized with the signature of Đôn, who had no idea that military action was to occur in the early hours of August 21 without his knowledge.[34][35]
