Wolf’s Lair (Poland). 'The Wolf’s Lair, Hitler’s headquarters during WWII, was so well designed that the Allies had no idea it existed until it was overrun by the Red Army in 1945. They might not have needed to had one of Hitler’s own men, Colonel Claus von Stauff enberg, been more successful in his bid to assassinate the Führer here six months earlier. The ramshackle location takes a little imagination to appreciate fully.' http://www.lonelyplanet.com/poland
During the violent months preceding the liberation of Paris, New Zealander Nancy Wake killed a German guard with a single karate chop to the neck, executed a woman who had been spying for the Germans, shot her way out of roadblocks and biked 70 hours through perilous Nazi checkpoints to deliver radio codes for the Allies. In spite of Hitler she lived to be 98; died Aug. of 2011 Look it all up. This lady was a true hero.
