Welter was among the 40 staff members who were put on trial by an American Military Tribunal at Dachau in November 1945. Dr. Franz Blaha, a Communist prisoner at Dachau, testified that Wilhelm Welter was responsible for the deaths of prisoners at Dachau, but he also stated that the only deaths that he could remember had occurred in 1944, which was a year after Welter had left the Dachau main camp to work for six months in the Friedrichshafen sub-camp of Dachau. Welter was found guilty by the American Military Tribunal and was executed by hanging on May 29, 1946.
Adolf Hitler became chancellor of Germany on January 30, 1933, and in March of that year the first Nazi concentration camp opened in the town of Dachau, just outside Munich, a major city in southern Germany. The camp initially housed political prisoners, and its first group of detainees consisted primarily of socialists and communists. Hilmar Wäckerle (1899-1941), an official in the “Schutzstaffel” (a Nazi paramilitary organization commonly known as the SS), served as the first commandant of Dachau.
December 8, 1941 - In occupied Poland, near Lodz, Chelmno extermination camp becomes operational. Jews taken there are placed in mobile gas vans and driven to a burial place while carbon monoxide from the engine exhaust is fed into the sealed rear compartment, killing them. The first gassing victims include 5,000 Gypsies who had been deported from the Reich to Lodz.
Oskar Schindler was a German who joined the Nazi Party for business reasons. Before the war, Schindler was known mainly for his interest in making quick money, drinking, and womanizing. Indeed, he saw the war at first as a chance to indulge in all three. Soon after the invasion of Poland, he came to the city of Kraków in search of business opportunities. With equal doses of bribery and charm, he managed to convince the Nazis that he was the right man to take over a failed cookware factory outside the city. He then proceeded to make a fortune turning out mess kits for German soldiers.
SS-Obergruppenführer Reinhard Heydrich, head of the Reich Main Security Office (Reichssicherheitshauptamt or RSHA), convened what became known as the Wannsee Conference on 20 January 1942 at Am Großen Wannsee 56–58, a villa in Berlin's Wannsee suburb. The meeting had been scheduled for 9 December 1941, and invitations had been sent on 29 November, but it had been postponed.
In the summer of 1941, the camp physician at Dachau was ordered to register those prisoners who were sick or unable to work. Some weeks later, a medical commission from Berlin arrived to pass judgement, and during the winter of 1941 -1942 “invalid transports” departed from Dachau in quick succession to the Hartheim castle, near Linz. Hartheim was one of the murder facilities included in the euthanasia programme. There 3166 inmates from Dachau were gassed.
The British forced the former SS camp personnel to help bury the thousands of dead bodies in mass graves. Some civil servants from Celle and Landkreis Celle were brought to Belsen and confronted with the crimes committed on their doorstep.:262 Military photographers and cameramen of No. 5 Army Film and Photographic Unit documented the conditions in the camp and the measures of the British Army to ameliorate them. Many of the pictures they took and the films they made from April 15 to June 9, 1945 were published or shown abroad. Today, the originals are in the Imperial War Museum. These documents had a lasting impact on the international perception and memory of Nazi concentration camps to this day.:243 According to Habbo Knoch, head of the institution that runs the memorial today: "Bergen-Belsen [...] became a synonym world-wide for German crimes committed during the time of Nazi rule.":9
Beginning in late 1941, the Germans began mass transports from the ghettoes in Poland to the concentration camps, starting with those people viewed as the least useful: the sick, old and weak and the very young. The first mass gassings began at the camp of Belzec, near Lublin, on March 17, 1942. Five more mass killing centers were built at camps in occupied Poland, including Chelmno, Sobibor, Treblinka, Majdanek and the largest of all, Auschwitz-Birkenau. From 1942 to 1945, Jews were deported to the camps from all over Europe, including German-controlled territory as well as those countries allied with Germany. The heaviest deportations took place during the summer and fall of 1942, when more than 300,000 people were deported from the Warsaw ghetto alone.
This has been a terrible day at the Belsen trial. First this morning all the courtroom, court, prisoners, press, and German spectators saw the films taken in camp by the British Army Film Photographic Unit just after British troops had liberated it. Then followed the evidence by the only Briton known to survive the camp—a Jersey schoolmaster named Harold Osmand le Drieullenac of St. Helier.
After the liberation of Dachau, the commanding officer of the Rainbow division, Major General Harry J. Collins, made sure that the Jewish survivors were taken care of properly. Some of the Jewish survivors were given private housing in homes in the town of Dachau after their owners had been evicted. In some cases, the home owners were allowed to live in the attic of their homes, but they were forbidden to remove any of the linens, china or silverware, which had to be left for the use of the new occupants. A few of the Jewish survivors settled in Dachau permanently after the war.
