ヴァルター・シェレンベルク
Hitler fired Canaris on the spot, and on 18 February 1944, Hitler signed a decree that abolished the "Abwehr". Its functions were taken over by the Reich Security Main Office (RSHA) and the senior RSHA official Walter Schellenberg replaced Canaris functionally within the RSHA. This action strengthened Himmler's control over the military.
