The dark history of Hitler's reign included millions of deaths, tortures and troubles. That hellish era also had the bitter reality of death camps that were established during World War II. Fort VII aka Konzentrationslager Posen, located in Poznan was the first death cantonment that started functioning in October 1939. The camp contained many gas chambers that were set for the mass extermination of the civilians.
It's been long 76 years, and we have got a list of photographs of the horrible camp that led to the death of more than 5,000 patients. The images are featured on DailyMail.
A large number of psychiatric patients were exposed to the lethal gas to kill them.
