24. Wilhelm Canaris began working against the Hitler regime following Pastorius
From the beginning of World War II, when Canaris learned of the Nazi einzatzgruppen executing Polish Jews, he vocally opposed the Nazi policies. Before the Germans invaded the Soviet Union Canaris had established contacts with the British government via MI6, through neutral Spain, Sweden, and possibly the Vatican. Following the failure of Operation Pastorius Hitler lost confidence in the Abwehr, but the General Staff retained Canaris in his post for reasons of their own. Throughout the remainder of his life, Canaris was under ever-increasing scrutiny by the SS and Gestapo, instigated by Himmler, who thoroughly detested the admiral.
In February, 1944, the Abwehr was abolished and its activities were taken over by the Reich Main Security Office. The Gestapo assumed many of the duties previously those of Canaris, and the Abwehr records were thoroughly scrutinized. Canaris was placed under house arrest, released in June, and arrested in July following the bomb plot against Hitler of that month. Canaris was hanged on April 9, 1945, at Flossenbuurg Concentration Camp. The architect of the sabotage plot known as Operation Pastorius died less than one month before the surrender of the Germans on the Western Front.
