Hasso von Boehmer, a colonel general in the General Staff, was married to K√§the Torhorst, with whom he had a daughter and two sons. His friend Henning von Tresckow won his support for the goals of the resistance groups around Ludwig Beck and Carl Goerdeler, and Boehmer then volunteered to act as liaison officer for the coup in Military District XX (Danzig). On the day of the attempt on Hitler's life, the commander of Military District XX, General Bodewin Keitel, brother of Field Marshal Wilhelm Keitel and Boehmer's superior, was on an inspection tour. In his capacity as Keitel's first officer, Hasso von Boehmer received the conspirators' telegrams arriving from Berlin. However, Keitel heard about the unsuccessful assassination attempt on the radio and immediately returned to Danzig. Boehmer was arrested on July 20, 1944, and shortly thereafter was brought to Berlin and held in the Lehrter Stra√üe Prison. In January 1945, he was transferred to the infirmary of the Sachsenhausen concentration camp. On March 5, 1945, he was sentenced to death by the People's Court and murdered in Berlin-Pl√∂tzensee that same day.
