Title: Warsaw concentration camp
Content:  The Warsaw concentration camp (in German, Konzentrationslager Warschau, KL Warschau; see other names), was a German concentration camp created on the order of Reichsführer-SS Heinrich Himmler on the ruins of the Warsaw Ghetto, on the base of the now nonexistent Gęsiówka prison in what is today the Warsaw neighbourhood of Muranów. It operated from July 1943 to August 1944. The Encyclopedia on Camps and Ghettos says that a total of some 8,000 to 9,000 inmates were held there.

Title: The Holocaust in Poland
Content:   The Auschwitz concentration camp was the largest of the German Nazi extermination centers. Located in the Gau Upper Silesia inside Nazi Germany, and 40 mi west of Kraków. The overwhelming majority of prisoners deported there were murdered within hours of their arrival. The camp was fitted with the first permanent gas chambers in March 1942. The extermination of Jews with Zyklon B as the killing agent began in July. At Birkenau, the four killing installations (each consisting of coatrooms, multiple gas chambers and industrial-scale crematoria) were built in the following year. By late 1943, Birkenau was engaged in industrial-scale murder, with four so-called 'Bunkers' (totaling over a dozen gas chambers) working around the clock. Up to 6,000 people were gassed and cremated there each day, after the ruthless 'selection process' at the Judenrampe. Only about 10 percent of

Title: Resistance movement in Auschwitz
Content:   After the western part of the country was annexed by Nazi Germany during the Nazi-Soviet invasion of Poland, Oświęcim (Auschwitz) was located administratively in the German Province of Upper Silesia, Regierungsbezirk Kattowitz. Auschwitz was first suggested as the location of a concentration camp for Polish nationals by SS-Oberführer Arpad Wigand, an aide to Higher SS and Police Leader for Silesia, Erich von dem Bach-Zelewski. Bach-Zelewski had been searching for a new site to intern people in the Silesia region because the local prisons were filled to capacity. Richard Glücks, head of the Concentration Camps Inspectorate, sent former Sachsenhausen concentration camp commandant Walter Eisfeld to inspect the site, which already held sixteen dilapidated one-story buildings that had once served as an Austrian and later

In November 1944 the Germans renamed it Monowitz concentration camp, after the village of Monowice (German: Monowitz) where it was built, in the annexed portion of Poland.

Content:  The Holocaust in East Upper Silesia resulted in the murder of most of the Jews living in East Upper Silesia during World War II. It is best known as the site of Auschwitz concentration camp, but it also hosted many of the forced-labor camps of Organization Schmelt and seventeen ghettos, including Sosnowiec Ghetto, Będzin Ghetto, and Dąbrowa Górnicza Ghetto.

Title: Sachsenhausen concentration camp
Content:   The camp was established in 1936. It was located 35 km north of Berlin, which gave it a primary position among the German concentration camps: the administrative centre of all concentration camps was located in Oranienburg, and Sachsenhausen became a training centre for Schutzstaffel (SS) officers (who would often be sent to oversee other camps afterwards). Initially, the camp was used to perfect the most efficient and effective execution method for use in the death camps. Given this, executions obviously took place at Sachsenhausen, especially of Soviet prisoners of war. During the earlier stages of the camp's existence the executions
