The man who smuggled himself into Auschwitz

Denis Avey is a remarkable man by any measure. A courageous and determined soldier in World War II, he was captured by the Germans and imprisoned in a camp connected to the Germans' largest concentration camp, Auschwitz. But his actions while in the camp - which he has never spoken about until now - are truly extraordinary. When millions would have done anything to get out, Mr Avey repeatedly smuggled himself into the camp. Now 91 and living in Derbyshire, he says he wanted to witness what was going on inside and find out the truth about the gas chambers, so he could tell others. He knows he took "a hell of a chance". "When you think about it in today's environment it is ludicrous, absolutely ludicrous," he says. "You wouldn't think anyone would think or do that, but that is how I was. I had red hair and a temperament to match. Nothing would stop me."
