Many refugees from Nazism were Germans and Austrians, and some had fought for Britain in the Second World War. Some were transferred into the Intelligence Corps and sent back to Germany and Austria in British uniform. However, German-speakers were small in number in the British zone, which was hampered by the language deficit. Due to its large German-American population, the US authorities were able to bring a larger number of German-speakers to the task of working in the Allied Military Government, although many were poorly trained. They were assigned to all aspects of military administration, the interrogation of POWs, collecting evidence for the War Crimes Investigation Unit and the search for war criminals.
