Zero night: the untold story of World War Two’s most daring great escape. Mark Felton. 2014.

Oflag VI-B, Warburg, Germany: On the night of 30 August 1942 - ‘Zero Night’ - 40 officers from Britain, Australia, New Zealand and South Africa staged the most audacious mass escape of World War Two.

It was the first ‘Great Escape’ - but instead of tunnelling, the escapers boldly went over the huge perimeter fences using wooden scaling contraptions. This was the notorious ‘Warburg Wire Job’, described by fellow prisoner and fighter ace Douglas Bader as ‘the most brilliant escape conception of this war’.

Months of meticulous planning and secret training hung in the balance during three minutes of mayhem as prisoners charged the camp’s double perimeter fences.
