In 1944, Allied airmen interned at Stalag Luft III (the supposedly escape-proof POW camp run by the Luftwaffe) performed the greatest prison escape in history. Masterminded by Roger Bushell of the RAF, the prisoners used everything at their disposal to mask their escape operations. In the end, they created a tunnel 30 feet deep, 336 feet long, and 87 prisoners managed to escape. Eventually, all but 3 escapees were recaptured or murdered by the Gestapo at Hitler's orders. A few dozen prisoners and history books are all that remains of this great escape from Stalag Luft III.
