Under the Wire
From Marc's list on the best POW escape books of World War 2.
One of the great "characters" of World War 2 escapes, "Tex" Ash was an American who travelled from his home state to Canada in order to enlist in the RCAF and fight the Nazis before the US entered the war. A Spitfire pilot of great bravery, Ash was shot down and captured in France. His tale of wild and woolly escapes and escapades makes for a rollicking good read. Some might say that his story is too far-fetched to be true; I believe every word of it.
