"The Great Escape" of World War II

During the tunneling process, X had been assisted by several American prisoners. Unfortunately, by the time the tunnel was completed in March, they had been transferred to another compound. Waiting a week for a moonless night, the escape commenced after dark on March 24, 1944. Breaking through the surface, the first escapee was stunned to find that the tunnel had come up short of the woods adjacent to the camp. Despite this, 76 men successfully transited the tunnel without detection, despite the fact that an air raid occurred during the escape which cut off power to the tunnel's lights. http://therealgreatescape.com/stalag-luft-iii/the-great-escape/
