Final Solution
Heinrich Himmler brought in a plan known as Operation Reinhard, named after SS General Reinhard Heydrich, who had been killed by Czech soldiers. Three camps were set up in Poland for the purpose of killing people. These were at Belzec, Sobibor and Treblinka. In 1942 more death camps were set up in Poland at Majdanek, Chelmno, and Auschwitz. By the end of World War II about six million people had been killed.
