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.
On April 29, the day after the German guards completed their gruesome task of 10 days of burying the 10,000 decomposed bodies with their bare hands, they were taken to the prison in the city of Celle, which is 16 kilometers northwest of the camp. Also on that day, April 29, 1945, American soldiers entered the Dachau concentration camp and discovered bodies of prisoners who had died of typhus. The next day, 97 medical students arrived in Bergen-Belsen to help with the sick prisoners, and on May 4th, more British medical units arrived. On that same day, May 4, 1945, part of the German Army surrendered to the British in the area near the camp.
And it turned out he had chosen the right man. Regulations soon established by Eicke included the standing order that any prisoner would be hanged who: "politicizes, holds inciting speeches and meetings, forms cliques, loiters around with others – who for the purpose of supplying the propaganda of the opposition with atrocity stories, collects true or false information about the concentration camp, receives such information, buries it, talks about it to others, smuggles it out of the camp into the hands of foreign visitors, etc."
The camp staff consisted mostly of SS males, although 19 female guards served at Dachau as well, most of them until liberation. Sixteen have been identified including Fanny Baur, Leopoldine Bittermann, Ernestine Brenner, Anna Buck, Rosa Dolaschko, Maria Eder, Rosa Grassmann, Betty Hanneschaleger, Ruth Elfriede Hildner, Josefa Keller, Berta Kimplinger, Lieselotte Klaudat, Theresia Kopp, Rosalie Leimboeck, and Thea Miesl. Women guards were assigned also to the Augsburg Michelwerke, Burgau, Kaufering, Mühldorf, and Munich Agfa Camera Werke subcamps. In mid-April 1945, female subcamps at Kaufering, Augsburg, and Munich were closed, and the SS stationed the women at Dachau. Several Norwegians worked as guards at the Dachau camp.
While the Nazis murdered other national and ethnic groups, such as a number of Soviet prisoners of war, Polish intellectuals, and gypsies, only the Jews were marked for systematic and total annihilation. Jews were singled out for "Special Treatment" (Sonderbehandlung), which meant that Jewish men, women and children were to be methodically killed with poisonous gas. In the exacting records kept at the Auschwitz death camp, the cause of death of Jews who had been gassed was indicated by "SB," the first letters of the two words that form the German term for "Special Treatment."
In the last months of Hitler’s Reich, as the German armies retreated, the Nazis began marching the prisoners still alive in the concentration camps to the territory they still controlled. The Germans forced the starving and sick Jews to walk hundreds of miles. Most died or were shot along the way. About a quarter of a million Jews died on the death marches.
The Dachau concentration camp opened on March 22, 1933. It was the first SS-run camp for "political prisoners" under Hitler's regime and became a model for the many SS prison camps that followed. Located in southern Germany, Dachau remained open until 1945 when it was liberated by U.S. troops. Approximately 200,000 people were detained during these years and an estimated 41,500 died.
Following the German invasion of the Soviet Union on June 22, 1941, Russian Prisoners of War were sent to Dachau. On Hitler's orders, Russian POWs who were determined to be Communist Commissars were executed at Dachau and other major concentration camps in Germany. The Communist Soviet Union had both political Commissars and military Commissars whose job it was to keep their citizens or soldiers in line. The military Commissars were stationed behind the front lines in order to urge reluctant Soviet soldiers forward since only one out of every 5 men had been furnished with a rifle. The Soviet soldiers were expected to pick up a rifle after another soldier had been shot; those who tried to retreat were shot by the Commissars. If captured, the Commissars were under orders to organize an escape or otherwise create havoc in the POW camp.
Sometimes the mere presence of German troops in the vicinity was sufficient to spur a massacre. One example is what happened in the Polish village of Jedwabne, where neighbours murdered their Jewish neighbours. For years the massacre was blamed on the Germans, though many Poles likely knew that the local population had turned against its own Jews. In the Baltics, where the Germans were greeted as liberators by some segments of the population, the lure of political independence and the desire to erase any collaboration with the previous Soviet occupiers led nationalist bands to murder local Jews.
Typhus, transmitted by body lice, which had been prevalent in the ghettos and death camps in occupied Poland throughout the war, now spread to the concentration camps in Germany. After January 1945, conditions in all of Germany and Austria, including the concentration camps, became intolerable due to the chaos caused by the intensive Allied bombing of civilian areas in all the major cities.
Throughout its 12-year history, Dachau was predominantly a camp for non-Jewish adult males. At first, the few women who were sent to Dachau lived with German families in the town of Dachau and worked as servants. In 1944, Jewish women were brought to Dachau from Hungary, but most of them were then transferred to some of the 123 Dachau sub-camps to work in German factories. Other women at Dachau were non-Jewish prostitutes who worked in a camp brothel for the inmates, which was set up in 1943. There were 11 prostitutes at the camp when it was liberated.
In April 1943, a part of the Bergen-Belsen camp was taken over by the SS Economic-Administration Main Office (SS Wirtschafts-Verwaltungshauptamt; WVHA). It thus became part of the concentration camp system, run by the SS Schutzstaffel but it was a special case. Having initially been designated a Zivilinterniertenlager ("civilian internment camp"), in June 1943 it was redesignated Aufenthaltslager ("holding camp"), since the Geneva Conventions stipulated that the former type of facility must be open to inspection by international committees. This "holding camp" or "exchange camp" was for Jews who were intended to be exchanged for German civilians interned in other countries, or for hard currency. The SS divided this camp into subsections for individual groups (the "Hungarian camp", the "special camp" for Polish Jews, the "neutrals camp" for citizens of neutral countries and the "Star camp" for Dutch Jews). Between the summer of 1943 and December 1944 at least 14,600 Jews, including 2,750 children and minors were transported to the Bergen-Belsen "holding" or exchange camp.:160 Inmates were made to work, many of them in the "shoe commando" which salvaged usable pieces of leather from shoes collected and brought to the camp from all over Germany and occupied Europe. In general the prisoners of this part of the camp were treated less harshly than some other classes of Bergen-Belsen prisoner until fairly late in the war, due to their perceived potential exchange value. However, only around 2,560 Jewish prisoners were ever actually released from Bergen-Belsen and allowed to leave Germany.
