Great Britain. MI9

MI9, the British Directorate of Military Intelligence Section 9, was a secret department of the War Office between 1939 and 1945. During World War II it had two principal tasks: assisting in the escape of Allied prisoners of war (POWs) held by the Axis countries, especially Nazi Germany; and helping Allied military personnel, especially downed airmen, evade capture after they were shot down or trapped behind enemy lines in Axis-occupied countries. During World War II, about 35,000 Allied military personnel, many helped by MI9, escaped POW camps or evaded capture and made their way to Allied or neutral countries after being trapped behind enemy lines. The best-known activity of MI9 was creating and supporting escape and evasion lines, especially in France and Belgium, which helped 5,000 downed British, American and other Allied airmen evade capture and return to duty. The usual routes of escape from occupied Europe were either south to Switzerland or to southern France and then over the Pyrenees to neutral Spain and Portugal. MI9 trained Allied soldiers and airmen in tactics for evading and escaping and helped prisoners of war to escape by establishing clandestine communications and providing escape devices to them.
