The Untold Story of The Second World War's Most Daring Great Escape. The thrilling true story of what happened at prison camp Oflag VI-B on 30 August 1943 - 'Zero Night.' Almost 50 British and Australian officers staged the most audacious mass escape of the Second World War at Warburg in Germany. Instead of tunnelling, the escapers boldly went over the huge perimeter fences using wooden scaling contraptions. Telling this remarkable story in full for the first time, the author brilliantly evokes the suspense of the escape itself and the adventures of those who eluded the Germans, as well as those who helped them in enemy territory.
