BBC News has an interesting bit of history about the first successful escape from the “escape-proof” prisoner-of-war camp at Colditz:
Forged papers used by a British escapee from Colditz to make one of the first “home runs” back to the UK from the notorious German prisoner-of-war camp are being sold along with his medals. The tale of his ingenuity and success has become the stuff of World War II legend.
Perched high on a rocky outcrop overlooking the River Mulde near Leipzig, eastern Germany, Colditz castle was considered by German authorities in WWII the ideal site for a high-security prison for allied officers with a history of trying to escape.
But despite its “escape proof” label, the Gothic building witnessed 174 attempts by its troublesome, spirited inmates.
Nevertheless, just 32 men were ever successful — and only half of these managed the feat from within the castle.
