Each Abwehr station throughout Germany was based on army districts and more offices were opened in amenable neutral countries and in the occupied territories as the greater Reich expanded.[5] The Ministry of Defense was renamed the Ministry of War in 1935 and then replaced by Adolf Hitler altogether with the new OKW. The OKW was part of the Führer's personal "working staff" from June 1938 and the Abwehr became its intelligence agency under Vice-Admiral Wilhelm Canaris.[6][lower-alpha 5] Its headquarters was located at 76/78 Tirpitzufer, Berlin, adjacent to the offices of the OKW.[lower-alpha 6]
