The prisoners are divided into three classifications, each treated differently. The first class is picked at random. These men act as firemen, and their only routine consists of some drilling. The second class is made up of the majority of the prisoners, who receive the treatment outlined above. The third class is composed of leading Communists and all the Jews. This class performs the hardest work on the smallest rations. They receive no sheets to cover their straw sacks. For a long time they were confined to dilapidated barracks where on rainy days the water would stand six inches deep on the floor. They are beaten more than the other prisoners, and nearly all of the murders are perpetrated on members of this class. Even within the last-mentioned class, the Jews are segregated, because no Aryan is allowed to share sleeping accommodations with a Jew. The Jews are refused cigarettes, and the other prisoners are forbidden to converse with them. However, the solidarity among the prisoners makes it impossible to put this rule into effect: camaraderie between the Jews and the other confined men is very strong. The prisoners are allowed to write one letter, or postcard, a week, which has to be turned in to the authorities unsealed. Any remarks about the conditions at the camp means daily beatings and severe punishment in dark cells.

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.
One of the most horrific terms in history was used by Nazi Germany to designate human beings whose lives were unimportant, or those who should be killed outright: Lebensunwertes Leben, or "life unworthy of life". The phrase was applied to the mentally impaired and later to the "racially inferior," or "sexually deviant," as well as to "enemies of the state" both internal and external. From very early in the war, part of Nazi policy was to murder civilians en masse, especially targeting Jews. Later in the war, this policy grew into Hitler's "final solution", the complete extermination of the Jews. It began with Einsatzgruppen death squads in the East, which killed some 1,000,000 people in numerous massacres, and continued in concentration camps where prisoners were actively denied proper food and health care. It culminated in the construction of extermination camps -- government facilities whose entire purpose was the systematic murder and disposal of massive numbers of people. In 1945, as advancing Allied troops began discovering these camps, they found the results of these policies: hundreds of thousands of starving and sick prisoners locked in with thousands of dead bodies. They encountered evidence of gas chambers and high-volume crematoriums, as well as thousands of mass graves, documentation of awful medical experimentation, and much more. The Nazis killed more than 10 million people in this manner, including 6 million Jews. (This entry is Part 18 of a weekly 20-part retrospective of World War II)

Since March 1945, around 15,000 new prisoners had been accommodated in a camp that was originally designed for 5,000 men. By the time the liberators arrived, there were over 30,000 prisoners in the camp. There was a typhus epidemic in the camp but the Germans had no DDT, nor typhus vaccine, available to stop it. Up to 400 prisoners per day were dying of typhus by the time that the Americans arrived. There was no coal to burn the bodies in the ovens and the staff could not keep up with burying the bodies in mass graves on a hill several miles from the camp.

After the SS re-designated Plaszow as a concentration camp in August 1943, Schindler persuaded the SS to convert Emalia into a subcamp of Plaszow. In addition to the approximately 1,000 Jewish forced laborers registered as factory workers, Schindler permitted 450 Jews working in other nearby factories to live at Emalia as well. This saved them from the systematic brutality and arbitrary murder that was part of daily life in Plaszow.

In February 1942, the Nazis began systematically rounding up all the Jews in Germany and the Nazi-occupied countries, and transporting them to what is now Poland or the area that is now Belarus, in a program of extermination, which had been planned at the Wannsee conference on January 20, 1942. The title of the conference was "The Final Solution to the Jewish Question."

Thus although the Nazi 'Final Solution' was one genocide among many, it had features that made it stand out from all the rest as well. Unlike all the others it was bounded neither by space nor by time. It was launched not against a local or regional obstacle, but at a world-enemy seen as operating on a global scale. It was bound to an even larger plan of racial reordering and reconstruction involving further genocidal killing on an almost unimaginable scale, aimed, however, at clearing the way in a particular region – Eastern Europe – for a further struggle against the Jews and those the Nazis regarded as their puppets. It was set in motion by ideologues who saw world history in racial terms. It was, in part, carried out by industrial methods. These things all make it unique.

By negotiations between British and German officers, British troops took over from the SS and the Wehrmacht the task of guarding the vast concentration camp at Belsen, a few miles northwest of Celle, which contains 60,000 prisoners, many of them political. This has been done because typhus is rampant in the camp and it is vital that no prisoners be released until the infection is checked. The advancing British agreed to refrain from bombing or shelling the area of the camp, and the Germans agreed to leave behind an armed guard which would be allowed to return to their own lines a week after the British arrival.

There were an additional 37,223 prisoners counted in the sub-camps near Dachau on April 26, 1945, the date of the last roll call. According to the US Army Report, there were approximately 7,000 prisoners who arrived at Dachau after April 26, 1945 who were not registered in the camp. They were prisoners from the sub-camps who had been evacuated to the main camp. One group of prisoners from a subcamp arrived on April 28th, escorted by Otto Moll, a notorious SS man who had formerly worked in the Auschwitz death camp.

On 6 January 1942, the Soviet Minister of Foreign Affairs, Vyacheslav Molotov, sent out diplomatic notes about German atrocities. The notes were based on reports about bodies surfacing from poorly covered graves in pits and quarries, as well as mass graves found in areas the Red Army had liberated, and on witness reports from German-occupied areas.[335] The following month, Szlama Ber Winer escaped from the Chełmno concentration camp in Poland, and passed detailed information about it to the Oneg Shabbat group in the Warsaw Ghetto. His report, known by his pseudonym as the Grojanowski Report, had reached London by June 1942.[288][336] Also in 1942, Jan Karski sent information to the Allies after being smuggled into the Warsaw Ghetto twice.[337][s] On 27 April 1942, Vyacheslav Molotov sent out another note about atrocities.[335] In late July or early August 1942, Polish leaders learned about the mass killings taking place inside Auschwitz. The Polish Interior Ministry prepared a report, Sprawozdanie 6/42,[340] which said at the end:
Yugoslavia and Greece were invaded in April 1941 and surrendered before the end of the month. Germany and Italy divided Greece into occupation zones but did not eliminate it as a country. Yugoslavia, home to around 80,000 Jews, was dismembered; regions in the north were annexed by Germany and regions along the coast made part of Italy. The rest of the country was divided into the Independent State of Croatia, nominally an ally of Germany, and Serbia, which was governed by a combination of military and police administrators.[167] According to historian Jeremy Black, Serbia was declared free of Jews in August 1942.[168] Croatia's ruling party, the Ustashe, killed the country's Jews, and killed or expelled Orthodox Christian Serbs and Muslims.[167] Jews and Serbs alike were "hacked to death and burned in barns", according to Black. One difference between the Germans and Croatians was that the Ustashe allowed its Jewish and Serbian victims to convert to Catholicism so they could escape death.[168]
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.

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.[1] This became the largest military training area in Germany of the time and was used for armoured vehicle training.[1] 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.
