MI9, the British Directorate of Military Intelligence Section 9, was a highly secret department of the War Office between 1939 and 1945. During World War II it had two principal tasks: (1) assisting in the escape of Allied prisoners of war (POWs) held by the Axis countries, especially Nazi Germany; and (2) helping Allied military personnel, especially downed airmen, evade capture after they were shot down or trapped behind enemy lines in Axis-occupied countries.
