Dachau was never a camp that was specifically intended for murdering the Jews; the Nazi plan was to consolidate all the Jews into ghettos, from which they were later sent to the death camps. German Jews were sent to the Lodz ghetto in what is now Poland where they worked in factories until 1944; those who could no longer work were sent to the Chelmno death camp. In 1942, the Jews who were still living in Germany were sent to the Theresienstadt ghetto in what is now the Czech Republic and from there to the gas chambers in Auschwitz-Birkenau.
These evacuations were regarded as provisional or "temporary solutions" ("Ausweichmöglichkeiten").[266][p] The final solution would encompass the 11 million Jews living not only in territories controlled by Germany, but elsewhere in Europe and adjacent territories, such as Britain, Ireland, Switzerland, Turkey, Sweden, Portugal, Spain, and Hungary, "dependent on military developments".[266] There was little doubt what the final solution was, writes Peter Longerich: "the Jews were to be annihilated by a combination of forced labour and mass murder".[268]
Despite, wide reporting of Holocaust atrocities including gas chambers, many prominent analysts doubted the authenticity of these reports. Prominently, Roger Allen, a member of the British Foreign Office discounted intelligence reports on the use of gas chambers in Polish extermination camps because he could “never understand what the advantage of a gas chamber over a simple machine gun or over starving people would be.”
The whole corner where the barracks stand is enclosed by a high wire entanglement. The prisoners are warned that these are live wires, but this is a false alarm. This enclosed area is about 1,800 feet square, and contains a pool filled with muddy water, which, shrewdly photographed, appeared in the Munich Illustrierte Zeitung of July 16, 1933, as a swimming pool for the prisoners. From this enclosure leads a gangway, also protected by barbed wire and machine guns, to a spacious workshop, part of which is the kitchen and the other part drill-room and mess hall. Farther away are the guard houses, equipped with heating facilities. They are the officers’ quarters and contain workshops for cobblers, cabinet-makers, etc.

Victims usually arrived at the camps by freight train.[278] Almost all arrivals at the Operation Reinhard camps of Treblinka, Sobibór, and Bełżec were sent directly to the gas chambers,[279] with individuals occasionally selected to replace dead workers.[280] At Auschwitz, camp officials usually subjected individuals to selections;[281] about 25%[282] of the new arrivals were selected to work.[281] Those selected for death at all camps were told to undress and hand their valuables to camp workers.[283] They were then herded naked into the gas chambers. To prevent panic, they were told the gas chambers were showers or delousing chambers.[284] The procedure at Chełmno was slightly different. Victims there were placed in a mobile gas van and asphyxiated, while being driven to prepared burial pits in the nearby forests. There the corpses were unloaded and buried.[285]
There are different methods of execution. People are shot by firing squads, killed by an "air hammer", and poisoned by gas in special gas chambers. Prisoners condemned to death by the Gestapo are murdered by the first two methods. The third method, the gas chamber, is employed for those who are ill or incapable of work and those who have been brought in transports especially for the purpose/Soviet prisoners of war, and, recently Jews.[333]
At Auschwitz, after the chambers were filled, the doors were shut and pellets of Zyklon-B were dropped into the chambers through vents,[293] releasing toxic prussic acid, or hydrogen cyanide.[294] Those inside died within 20 minutes; the speed of death depended on how close the inmate was standing to a gas vent, according to the commandant Rudolf Höss, who estimated that about one-third of the victims died immediately.[295] Johann Kremer, an SS doctor who oversaw the gassings, testified that: "Shouting and screaming of the victims could be heard through the opening and it was clear that they fought for their lives."[296] The gas was then pumped out, the bodies were removed, gold fillings in their teeth were extracted, and women's hair was cut.[297] The work was done by the Sonderkommando, work groups of mostly Jewish prisoners.[298] At Auschwitz, the bodies were at first buried in deep pits and covered with lime, but between September and November 1942, on the orders of Himmler, they were dug up and burned. In early 1943, new gas chambers and crematoria were built to accommodate the numbers.[299]
Medical experiments conducted on camp inmates by the SS were another distinctive feature.[51] At least 7,000 prisoners were subjected to experiments; most died as a result, during the experiments or later.[52] Twenty-three senior physicians and other medical personnel were charged at Nuremberg, after the war, with crimes against humanity. They included the head of the German Red Cross, tenured professors, clinic directors, and biomedical researchers.[53] Experiments took place at Auschwitz, Buchenwald, Dachau, Natzweiler-Struthof, Neuengamme, Ravensbrück, Sachsenhausen, and elsewhere. Some dealt with sterilization of men and women, the treatment of war wounds, ways to counteract chemical weapons, research into new vaccines and drugs, and the survival of harsh conditions.[52]
The Mühlbach, a man made canal, is diverted from the river Amper at the electrical power plant and runs parallel and flows back into it after passing the paper mill. The name derives from the frequent mills in former times along the canal which took advantage of the decline between Mühlbach and Amper. West of the so-called Festwiese runs another canal, called Lodererbach.
The workers who constructed the original buildings were housed in camps near Fallingbostel and Bergen, the latter being the so-called Bergen-Belsen Army Construction Camp.[1] Once the military complex was completed in 1938/39, the workers' camp fell into disuse. However, after the German invasion of Poland in September 1939, the Wehrmacht began using the huts as a prisoner of war (POW) camp.
