In the waning days of the Second World War, five days after Hitler shot himself in his bunker in Berlin, one of the most bizarre battle took place at a 19th century castle in the Austrian Alps. Castle Schloss Itter, located on a hill close to the village Itter, had some very prominent French personalities held prisoners by the SS. After the prison's guards fled, the hardy prisoners took arms and fought side-by-side along with American and German troops against the Nazis. The Battle of Castle Itter was the only battle of Word War 2 where Allied forces battled alongside the German troops.
