Dachau concentration camp Dachau concentration camp (German: "Konzentrationslager (KZ) Dachau" , ] ) was the first of the Nazi concentration camps opened in Germany, intended to hold political prisoners. It is located on the grounds of an abandoned munitions factory northeast of the medieval town of Dachau, about 16 km northwest of Munich in the state of Bavaria, in southern Germany. Opened in 1933 by Heinrich Himmler, its purpose was enlarged to include forced labor, and eventually, the imprisonment of Jews, German and Austrian criminals, and eventually foreign nationals from countries that Germany occupied or invaded. The Dachau camp system grew to include nearly 100 sub-camps, which were mostly work camps or "Arbeitskommandos ", and were located throughout southern Germany and Austria. The camps were liberated by U.S. forces on 1 May 1945.
Sobibór extermination camp Sobibór (or Sobibor , or , ] ) was a Nazi German extermination camp built and operated by the SS near the railway station of Sobibór during World War II, within the semi-colonial territory of General Government of the occupied Second Polish Republic. The camp was part of the secretive Operation Reinhard, which marked the deadliest phase of the Holocaust in German-occupied Poland. The camp was situated near the rural county's major town of Włodawa (called "Wolzek" by the Germans), 85 km south of the provincial capital, Brest-on-the-Bug (Brześć nad Bugiem in Polish). Its official German name was "SS-Sonderkommando Sobibór". Jews from Poland, France, Germany, the Netherlands, Czechoslovakia and the Soviet Union (including Jewish-Soviet POWs), were transported to Sobibór by rail. Most were suffocated in gas chambers fed by the exhaust of a large petrol engine. Up to 200,000 people were murdered at Sobibór and possibly more. At the postwar trial against the former "SS" personnel of Sobibór, held in Hagen two decades into the Cold War, Professor Wolfgang Scheffler estimated the number of murdered Jews totalled a minimum of 250,000. This would make it the fourth worst extermination camp, after Bełżec, Treblinka, and Auschwitz.
