The German press has repeatedly announced that great numbers of prisoners have been released and that several of the concentration camps have been closed. To illustrate the credibility of such statements, the happenings on Hitler’s birthday are significant. The press declared that two thousand prisoners were released in southern Bavaria, which means that at least fifteen hundred would have to have been released from the Dachau concentration camp. Actually ninety-nine men were released and twenty-five of them were imprisoned again the next day.
These experiments were usually exceptionally painful and unneeded. For example, Nazi Dr. Sigmund Rascher subjected some prisoners to high altitude experiments using pressure chambers, while he forced others to undergo freezing experiments so that their reactions to hypothermia could be observed. Still, other prisoners were forced to drink saltwater during efforts to determine its drinkability.
I was surprised to find records, going back for two or three years, of large quantities of food cooked daily for distribution. I became convinced, contrary to popular opinion, that there had never been a policy of deliberate starvation. This was confirmed by the large numbers of well-fed inmates. Why then were so many people suffering from malnutrition? [...]
Medical experiments conducted on camp inmates by the SS were another distinctive feature. At least 7,000 prisoners were subjected to experiments; most died as a result, during the experiments or later. 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. 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.
In nearly every country overrun by the Nazis, the Jews were forced to wear badges marking them as Jews, they were rounded up into ghettos or concentration camps and then gradually transported to the killing centers. The death camps were essentially factories for murdering Jews. The Germans shipped thousands of Jews to them each day. Within a few hours of their arrival, the Jews had been stripped of their possessions and valuables, gassed to death, and their bodies burned in specially designed crematoriums. Approximately 3.5 million Jews were murdered in these death camps.
Throughout the 1930s, the legal, economic, and social rights of Jews were steadily restricted. On 1 April 1933, there was a boycott of Jewish businesses. On 7 April 1933, the Law for the Restoration of the Professional Civil Service was passed, which excluded Jews and other "non-Aryans" from the civil service. Jews were disbarred from practising law, being editors or proprietors of newspapers, joining the Journalists' Association, or owning farms. In Silesia, in March 1933, a group of men entered the courthouse and beat up Jewish lawyers; Friedländer writes that, in Dresden, Jewish lawyers and judges were dragged out of courtrooms during trials. Jewish students were restricted by quotas from attending schools and universities. Jewish businesses were targeted for closure or "Aryanization", the forcible sale to Germans; of the approximately 50,000 Jewish-owned businesses in Germany in 1933, about 7,000 were still Jewish-owned in April 1939. Works by Jewish composers, authors, and artists were excluded from publications, performances, and exhibitions. Jewish doctors were dismissed or urged to resign. The Deutsches Ärzteblatt (a medical journal) reported on 6 April 1933: "Germans are to be treated by Germans only."
But in the spring of 1945, photographs and eyewitness accounts from the liberation of camps like Bergen-Belsen afforded the disbelieving world outside of Europe its first glimpse into the abyss of Nazi depravity. All these years later, after countless reports, books, oral histories and documentary films have constructed a terrifyingly clear picture of the Third Reich's vast machinery of murder, it's difficult to grasp just how shocking these first revelations really were. The most horrific rumors about what was happening to the Jews and millions of other "undesirables—Catholics, pacifists, homosexuals, Slavs—in Nazi-occupied lands paled before the reality revealed by the liberation of the camps.
The photograph below shows Dachau prisoners marching in single file, as they pass the newly constructed administration building that now houses the Museum at Dachau. These prisoners might be on their way to the factories which were just outside the "Arbeit Macht Frei" gate on the west side of the administration building, or they might be marching to pick up construction materials. Usually, an orchestra was playing at Dachau as the prisoners marched to work.
In 1935 the Wehrmacht began to build a large military complex close to the village of Belsen, a part of the town of Bergen, in what was then the Province of Hanover. This became the largest military training area in Germany of the time and was used for armoured vehicle training. The barracks were finished in 1937. The camp has been in continuous operation since then and is today known as Bergen-Hohne Training Area. It is used by the NATO armed forces.
