The myth of Colditz, the most infamous prison in history, has stood unchallenged for 70 years: prisoners of war, mustaches firmly set on stiff upper lips, defying the Nazis by tunnelling out of a grim Gothic castle on a German hilltop. Like all legends, that story contains only part of the truth. In Ben Macintyre's brilliant, cliche-smashing new history, he offers a vision of Colditz previously unimagined, a story of much more than an escape, just as the prison's inamtes were far more complicated than the cardboard saints depicted in post-war pop culture. Colditz was a miniature replica of office-class society at the time, only far stranger: a lethal, high stakes boarding school surrounded by barbed wire, initially containing prisoners of all Allied nations, including Canada, but eventually only Britons and Americans, a heavily guarded cage with its own culture, eccentricities, and internal tensions. In intimate and compelling detail, Macintyre explores what happens to people when they are locked up without committing a crime and with no idea when or if they might be liberated.
