High Quality Content by WIKIPEDIA articles! Franz Xaver Graf von Werra (13 July 1914 – 25 October 1941) was a German World War II fighter pilot and flying ace who was shot down over England and captured. He is generally regarded as the only Axis prisoner of war to succeed in escaping from a Canadian prisoner of war camp and returning to Germany, though a second man, a U-Boat rating named Walter Kurt Reich is said to have jumped from a Polish troopship (presumably the ex-liner Sobieski) in the St. Lawrence river in July 1940. Von Werra managed to return to Germany via the USA, Mexico, South America and Spain to reach Germany on 18 April 1941. Oberleutnant von Werra was awarded the Ritterkreuz on 14 December 1940.
