All of the Dachau proceedings were conducted by US Army Military Tribunals in which the accused were presumed to be guilty; most of the interrogators, prosecutors and judges were Jews, many of whom were foreign-born American citizens. After the Jewish interrogators in the Malmédy trial were accused of torturing the Waffen-SS soldiers into confessing, a Congressional investigation was conducted, and by December 1957, all of the convicted men in this case had been released.
Prof. Dr. Klaus Schilling, a renowned expert on malaria, was persuaded to come out of retirement in order to conduct medical experiments on approximately 1,200 Dachau prisoners in an attempt to find a cure for malaria after German troops began fighting the Allies in North Africa. Hundreds died as a result of Dr. Schilling's experiments, including a few who died from malaria and others who died from other diseases after being weakened by malaria. The subjects for the malaria experiments were the Catholic priests in the camp because they were not required to work, and would not be missed in the labor force if they died.
During much of the 12th century, Dachau was the primary residence of a smaller branch from the House of Wittelsbach led by Otto I, Count of Scheyern-Dauchau. When Conrad III died in 1182, Duke Otto I of Bavaria purchased the land and granted it market rights, that were then affirmed between 1270 and 1280 by Duke Ludwig II der Strenge (the Strict).[4]
The Commander enters the room where prisoners are mending boots and reads aloud an article on the situation in the concentration camp in Dachau, taken from the Vienna Arbeiter Zeitung. The paper states the prisoners are beaten with oxtails and shot “when caught in the attempt to escape” or are found “hanging in their cells.” Every prisoner knows that the report is true. The Commander asks: “Are you now convinced of the lies published by this Marxist Jewish press?” No one answers.
Killing on a mass scale using gas chambers or gas vans was the main difference between the extermination and concentration camps.[269] From the end of 1941, the Germans built six extermination camps in occupied Poland: Auschwitz II-Birkenau, Majdanek, Chełmno, and the three Operation Reinhard camps at Belzec, Sobibor, and Treblinka II.[44][270] Maly Trostenets, a concentration camp in the Reichskommissariat Ostland, became a killing centre in 1942.[44] Gerlach writes that over three million Jews were murdered in 1942, the year that "marked the peak" of the mass murder of Jews.[271] At least 1.4 million of these were in the General Government area of Poland.[272]

A victim of Nazi medical experimentation. A victim's arm shows a deep burn from phosphorus at Ravensbrueck, Germany, in November of 1943. The photograph shows the results of a medical experiment dealing with phosphorous that was carried out by doctors at Ravensbrueck. In the experiment, a mixture of phosphorus and rubber was applied to the skin and ignited. After twenty seconds, the fire was extinguished with water. After three days, the burn was treated with Echinacin in liquid form. After two weeks the wound had healed. This photograph, taken by a camp physician, was entered as evidence during the Doctors Trial at Nuremberg. #

British servicemen Denis Norden and Eric Sykes, who later became popular comedians, stumbled upon the camp in 1945 shortly after liberation; "Appalled, aghast, repelled - it is difficult to find words to express how we felt as we looked upon the degradation of some of the inmates not yet repatriated," Sykes later wrote. "They squatted in their thin, striped uniforms, unmoving bony structures who could have been anywhere between 30 and 60 years old, staring ahead with dead, hopeless eyes and incapable of feeling any relief at their deliverance."[44]
The gates of the camp had been locked again, and the liberators of the first hour, on their way again, were already far off, toward Munich, toward the south, pursuing their war. Guards had been placed on the other side of the barbed wire. No one was allowed out any more, Already, at the end of this first day, the Americans wondered what they would do with his rabble of lepers.
As the tide of World War II turned against the Nazis, they began a systematic plan to eliminate or "liquidate" the ghettos they had established, by a combination of mass murder on the spot and transferring the remaining residents to extermination camps. When the Nazis attempted to liquidate the Warsaw Ghetto on April 13, 1943, the remaining Jews fought back in what has become known as the Warsaw Ghetto Uprising. The Jewish resistance fighters held out against the entire Nazi regime for 28 days, longer than many European countries had been able to withstand Nazi conquest.

Although Dachau was in existence for 12 years, most people know only the horror described by the soldiers in the 42nd Rainbow Infantry Division and the 45th Thunderbird Infantry Division after they had liberated the camp on April 29, 1945. Three weeks before, on April 9, 1945, a bomb had hit the camp, knocking out a water main and the source of electricity. There was no running water in the camp and drinking water had to be brought in by trucks. There was no water for the showers, nor any water to flush the toilets. There was however, one last vestige of what the camp had been like before Germany was bombed back to the Stone age: fresh flowers in a vase in the undressing room for the gas chamber.

The first major camp to be encountered by Allied troops, Majdanek, was discovered by the advancing Soviets on 25 July 1944.[375] Treblinka, Sobibór, and Bełżec were never liberated, but were destroyed by the Germans in 1943.[376] Auschwitz was liberated, also by the Soviets, on 27 January 1945;[377] Buchenwald by the Americans on 11 April;[378] Bergen-Belsen by the British on 15 April;[379] Dachau by the Americans on 29 April;[380] Ravensbrück by the Soviets on 30 April;[381] and Mauthausen by the Americans on 5 May.[382] The Red Cross took control of Theresienstadt on 4 May, days before the Soviets arrived.[383][384]

In April, 1943, the camp was converted to a concentration camp, primarily for Jews with foreign passports who could be exchanged for German nationals imprisoned abroad. The camp was renamed Bergen-Belsen. Few Jewish prisoners were ever exchanged for imprisoned Germans, although 200 Jews were allowed to emigrate to Palestine in exchange for German citizens, and more than 1,500 Hungarian Jews were able to purchase emigration to Switzerland.

In December 1944 SS-Hauptsturmführer Josef Kramer, previously at Auschwitz-Birkenau, became the new camp commandant, replacing SS-Hauptsturmführer Adolf Haas [de], who had been in post since the spring of 1943.[7] In January 1945, the SS took over the POW hospital and increased the size of Bergen-Belsen. As eastern concentration camps were evacuated before the advance of the Red Army, at least 85,000 people were transported in cattle cars or marched to Bergen-Belsen.[14] Before that the number of prisoners at Belsen had been much smaller. In July 1944 there were 7,300; by December 1944 the number had increased to 15,000; and by February 1945 it had risen to 22,000. Numbers then soared to around 60,000 by April 15, 1945.[7] This overcrowding led to a vast increase in deaths from disease: particularly typhus, as well as tuberculosis, typhoid fever, dysentery and malnutrition in a camp originally designed to hold about 10,000 inmates. At this point also, the special status of the exchange prisoners no longer applied. All inmates were subject to starvation and epidemics.[14]
