In the afternoon , Minh ordered his bodyguard , Nguyễn Văn Nhung , to arrest , and later execute , Colonel Lê Quang Tung , one of Diệm 's closest and most faithful associates . The generals hated Tung , because , at Ngô Đình Nhu 's instructions , he had disguised his men in regular army uniforms and framed the army for the Xá Lợi Pagoda raids several months earlier , in August . At nightfall , Nhung took Tung and Major Lê Quảng Trịeu , his brother and deputy and drove them to the edge of the air base . Forced to kneel over two freshly dug holes , the brothers were shot into their graves and buried . In the early morning of 2 November , Diệm agreed to surrender . The ARVN officers had reportedly originally intended merely to exile Diệm and Nhu , having promised them safe passage "
