Although the Treaty of Versailles prohibited the Germans from establishing an intelligence organization of their own, they formed an espionage group in 1920 within the Ministry of Defence, calling it the Abwehr. The Ministry of Defence 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. Its headquarters was located at 76/78 Tirpitzufer, Berlin, adjacent to the offices of the OKW. --- **Keywords:** mine, hash
