as a WW2 history buff, trust me it happened & was worse than you could ever amagine. at it's high point, the Aushwitz ss garrison exterminated 15,000 people a day, there were mountains of ash. U.S. Army forces liberated Aushwitz,Dachau,Trablinka,Sobebor,Buckenwald, & many other labor camps. it's scary that so many people don't know there history
