In a forbidding Gothic castle on a hilltop in the heart of Nazi Germany, an unlikely band of British officers spent the Second World War plotting daring escapes from their German captors. Or so the story of Colditz has gone, unchallenged for 70 years. But that tale contains only part of the truth. The astonishing inside story, revealed for the first time in this new book by bestselling historian Ben Macintyre, is a tale of the indomitable human spirit, but also one of snobbery, class conflict, homosexuality, bullying, espionage, boredom, insanity and farce.
