In early 1937, the SS, using prisoner labor, initiated construction of a large complex of buildings on the grounds of the original camp. The construction was officially completed in mid-August 1938 and the camp remained essentially unchanged and in operation until 1945. A crematorium that was next to, but not directly accessible from within the camp, was erected in 1942. KZ Dachau was therefore the longest running concentration camp of the Third Reich. The Dachau complex included other SS facilities beside the concentration camp—a leader school of the economic and civil service, the medical school of the SS, etc. The camp at that time was called a "protective custody camp," and occupied less than half of the area of the entire complex.[13]

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.
Before and after the March 1933 Reichstag elections, the Nazis intensified their campaign of violence against opponents.[77] They set up concentration camps for extrajudicial imprisonment.[78] One of the first, at Dachau, opened on 9 March 1933.[79] Initially the camp contained mostly Communists and Social Democrats.[80] Other early prisons were consolidated by mid-1934 into purpose-built camps outside the cities, run exclusively by the SS.[81] The initial purpose of the camps was to serve as a deterrent by terrorizing Germans who did not conform.[82]
The Nazis considered Jews to be the main danger to Germany. Jews were the primary victims of Nazi racism, but other victims included Roma (Gypsies) and people with mental or physical disabilities. The Nazis murdered some 200,000 Roma. And they murdered at least 250,000 mentally or physically disabled patients, mainly German and living in institutions, in the so-called Euthanasia Program.

Himmler ordered the closure of ghettos in Poland in mid-July 1942; most inhabitants were sent to extermination camps. Those Jews needed for war production would be confined in concentration camps.[220] The deportations from the Warsaw Ghetto began on 22 July; over the almost two months of the Aktion, until 12 September, the population was reduced from 350,000 to 65,000. Those deported were transported in freight trains to the Treblinka extermination camp.[221] Similar deportations happened in other ghettos, with many ghettos totally emptied.[222] The first ghetto uprisings occurred in mid-1942 in small community ghettos.[223] Although there were armed resistance attempts in both the larger and smaller ghettos in 1943, in every case they failed against the overwhelming German military force, and the remaining Jews were either killed or deported to the death camps.[224]

In April 1942, at the same time that the Jews were being sent to the death camps in the East, a new brick building called Baracke X was planned for the Dachau camp. It was designed to house a homicidal gas chamber, disguised as a shower room, and four cremation ovens. The new Baracke X also has four disinfection gas chambers, designed to kill lice in clothing with the use of Zyklon-B, the same poison gas that was used to kill the Jews in the homicidal gas chambers at Majdanek and Auschwitz. The clothing was disinfected in all the Nazi camps in an attempt to prevent typhus which is spread by lice.
 In October 1944, after the SS transferred the Emalia Jews to Plaszow, Schindler sought and obtained authorization to relocate his plant to Brünnlitz (Brnenec) in Moravia, and reopen it exclusively as an armaments factory. One of his assistants drew several versions of a list of up to 1,200 Jewish prisoners needed to work in the new factory. These lists came to be known collectively as “Schindler's List.” Schindler met the specifications required by the SS to classify Brünnlitz as a subcamp of Gross-Rosen concentration camp and thereby facilitated the survival of around 800 Jewish men whom the SS deported from Plaszow via Gross-Rosen to Brünnlitz and between 300 and 400 Jewish women from Plaszow via Auschwitz.

An emaciated 18-year-old Russian girl looks into the camera lens during the liberation of Dachau concentration camp in 1945. Dachau was the first German concentration camp, opened in 1933. More than 200,000 people were detained between 1933 and 1945, and 31,591 deaths were declared, most from disease, malnutrition and suicide. Unlike Auschwitz, Dachau was not explicitly an extermination camp, but conditions were so horrific that hundreds died every week. #
Schindler moved to West Germany after the war, where he was supported by assistance payments from Jewish relief organisations. After receiving a partial reimbursement for his wartime expenses, he moved with his wife, Emilie, to Argentina, where they took up farming. When he went bankrupt in 1958, Schindler left his wife and returned to Germany, where he failed at several business ventures and relied on financial support from Schindlerjuden ("Schindler Jews")—the people whose lives he had saved during the war. He and his wife, Emilie, were named Righteous Among the Nations by the Israeli government in 1993. He died on 9 October 1974 in Hildesheim, Germany, and was buried in Jerusalem on Mount Zion, the only member of the Nazi Party to be honoured in this way.
Dachau prisoners were used as forced laborers. At first, they were employed in the operation of the camp, in various construction projects, and in small handicraft industries established in the camp. Prisoners built roads, worked in gravel pits, and drained marshes. During the war, forced labor utilizing concentration camp prisoners became increasingly important to German armaments production.
Even before the Nazis came to power in Germany in 1933, they had made no secret of their anti-Semitism. As early as 1919 Adolf Hitler had written, “Rational anti-Semitism, however, must lead to systematic legal opposition.…Its final objective must unswervingly be the removal of the Jews altogether.” In Mein Kampf (“My Struggle”; 1925–27), Hitler further developed the idea of the Jews as an evil race struggling for world domination. Nazi anti-Semitism was rooted in religious anti-Semitism and enhanced by political anti-Semitism. To this the Nazis added a further dimension: racial anti-Semitism. Nazi racial ideology characterized the Jews as Untermenschen (German: “subhumans”). The Nazis portrayed the Jews as a race and not as a religious group. Religious anti-Semitism could be resolved by conversion, political anti-Semitism by expulsion. Ultimately, the logic of Nazi racial anti-Semitism led to annihilation.
On March 22, 1933, a few weeks after Adolf Hitler had been appointed Reich Chancellor, a concentration camp for political prisoners was set up in Dachau. This camp served as a model for all later concentration camps and as a "school of violence" for the SS men under whose command it stood. In the twelve years of its existence over 200.000 persons from all over Europe were imprisoned here and in the numerous subsidary camps. 41.500 were murdered. On April 29 1945, American troops liberated the survivors.
With this police infrastructure in place, opponents of the Nazis were terrorized, beaten, or sent to one of the concentration camps the Germans built to incarcerate them. Dachau, just outside of Munich, was the first such camp built for political prisoners. Dachau's purpose changed over time and eventually became another brutal concentration camp for Jews.
Young boys of the Hitler Youth were brought to see the dead bodies on the train. Mutilated corpses of SS guards, who had been killed by the Americans after discovering the train, were lying nearby. Before the corpses in the camp were finally given a decent burial, the stench could be smelled up to a mile away, according to the American liberators. When the bodies of the typhus victims were finally taken to the cemetery on a hill called Leitenberg for burial by the citizens of Dachau, the horse-drawn wagons had to be driven slowly though the town, on the orders of the American military, so that the town's people would be forced to confront the horror of what the Nazis had done.
More camps opened in the spring and summer of 1942, when the Nazis began systematically clearing the ghettos in Poland and rounding up Jews in western Europe for 'deportation to the East'. The killing of the Polish Jews, code-named 'Project Reinhardt', was carried out in three camps: Treblinka, near Warsaw (850,000 victims); Belzec, in south-eastern Poland (650,000 victims); and Sobibor, in east-central Poland (250,000 victims). Some Jews from western Europe were sometimes taken to these camps as well, but most were killed at the biggest and most advanced of the death camps, Auschwitz.
After 1942, the economic functions of the camps, previously secondary to their penal and terror functions, came to the fore. Forced labor of camp prisoners became commonplace.[182] The guards became much more brutal, and the death rate increased as the guards not only beat and starved prisoners, but killed them more frequently.[186] Vernichtung durch Arbeit ("extermination through labor") was a policy—camp inmates would literally be worked to death, or to physical exhaustion, at which point they would be gassed or shot.[187] The Germans estimated the average prisoner's lifespan in a concentration camp at three months, due to lack of food and clothing, constant epidemics, and frequent punishments for the most minor transgressions.[188] The shifts were long and often involved exposure to dangerous materials.[189]
Among the key revelations in Crowe’s book: Oskar Schindler did not write out a list of people to save, he didn’t break down in tears because he thought he could have saved more people, and it is unlikely he experienced a defining moment, such as seeing a girl in a red coat, that led to his decision to save the lives of his Jewish workers. Steven Spielberg’s movie Schindler’s List, while important, impressive and admirable in many ways, took creative license on these and other issues.
Timothy D. Snyder (Bloodlands: Europe Between Hitler and Stalin, 2010): "In this book the term Holocaust signifies the final version of the Final Solution, the German policy to eliminate the Jews of Europe by murdering them. Although Hitler certainly wished to remove the Jews from Europe in a Final Solution earlier, the Holocaust on this definition begins in summer 1941, with the shooting of Jewish women and children in the occupied Soviet Union. The term Holocaust is sometimes used in two other ways: to mean all German killing policies during the war, or to mean all oppression of Jews by the Nazi regime. In this book, Holocaust means the murder of the Jews in Europe, as carried out by the Germans by guns and gas between 1941 and 1945."[23]

As Lise described the meeting, across barbed wire when the guard was occupied elsewhere, Anne told her that she had no one. She believed her father and mother were dead; her sister was very ill. Lise remembered, "After her sister died, she was just without hope. But she didn't know [that her father was alive], and so she had really nothing to live for."
The camp of huts near Fallingbostel became known as Stalag XI-B and was to become one of the Wehrmacht's largest POW camps, holding up to 95,000 prisoners from various countries.[6] In June 1940, Belgian and French POWs were housed in the former Bergen-Belsen construction workers' camp. This installation was significantly expanded from June 1941, once Germany prepared to invade the Soviet Union, becoming an independent camp known as Stalag XI-C (311). It was intended to hold up to 20,000 Soviet POWs and was one of three such camps in the area. The others were at Oerbke (Stalag XI-D (321)) and Wietzendorf (Stalag X-D (310)). By the end of March 1942, some 41,000 Soviet POWs had died in these three camps of starvation, exhaustion, and disease. By the end of the war, the total number of dead had increased to 50,000.[6] When the POW camp in Bergen ceased operation in early 1945, as the Wehrmacht handed it over to the SS, the cemetery contained over 19,500 dead Soviet prisoners.
