At the age of nineteen, Glasgow-born John McCallum signed up as a Supplementary Reservist in the Signal Corps. A little over a year later, he was in France, working frantically to set up communication lines as Europe once more hurtled towards war. Wounded and captured at Boulogne, he was sent to the notorious Stalag VIIIB prison camp, together with his brother, Jimmy, and friend Joe Harkin. Ingenious and resourceful, the three men set about planning their escape. With the help of Traudl, a local girl, they put their plan into action. In an astonishing coincidence, they passed through the town of Sagan, around which the seventy-six airmen of the Great Escape were being pursued and caught.

However, unlike most of these other escapees, John, Jimmy and Joe eventually made it to freedom. Now, due to the declassification of documents under the Official Secrets Act, John McCallum is finally able to tell the thrilling story of his adventure, in which he recaptures all the danger, audacity and romance of one of the most daring escapes of the Second World War.
