In spring 1942, Royal Air Force pilot Bill Ash’s plane was shot down by Germans, who captured and eventually brought him to Stalag Luft III, a notorious camp for prisoners of war. The Germans boasted that the camp - which was isolated, heavily guarded, and surrounded by wire fences - was escape proof. But Ash was ready to prove them wrong. He, along with other POWs, would dig tunnels, hide in shower drains, or jump on trucks - all in the name of freedom. Because resisting the Germans was their mission, and escaping was their duty.
