Not long after acquiring his “Emalia” factory - which produced enamel goods and munitions to supply the German front - the removal of Jews to death camps began in earnest. Schindler's Jewish accountant put him in touch with the few Jews with any remaining wealth. They invested in his factory, and in return they would be able to work there and perhaps be spared. He was persuaded to hire more Jewish workers, designating their skills as “essential,” paying off the Nazis so they would allow them to stay in Kraków. Schindler was making money, but everyone in his factory was fed, no-one was beaten, no-one was killed. It became an oasis of humanity in a desert of moral torpor.
The Nazis regarded the Slavs as subhuman, or Untermenschen.[426] In a secret memorandum dated 25 May 1940, Himmler stated that it was in German interests to foster divisions between the ethnic groups in the East. He wanted to restrict non-Germans in the conquered territories to schools that would only teach them how to write their own name, count up to 500, and obey Germans.[427][y] In November 1939 German planners called for "the complete destruction" of all Poles[430] and resettlement of the land by German colonists.[431] The Polish political leadership was the target of a campaign of murder (Intelligenzaktion and AB-Aktion).[432] Between 1.8 and 1.9 million non-Jewish Polish citizens perished at German hands during the course of the war; about four-fifths were ethnic Poles and the rest Ukrainians and Belarusians.[410] At least 200,000 died in concentration camps, around 146,000 in Auschwitz. Others died in massacres or in uprisings such as the Warsaw Uprising, where 120,000–200,000 were killed.[433] During the occupation, the Germans adopted a policy of restricting food and medical services, as well as degrading sanitation and public hygiene.[434] The death rate rose from 13 per 1000 before the war to 18 per 1000 during the war.[435] Around 6 million of World War II victims were Polish citizens; half the death toll were Jews.[436] Over the course of the war Poland lost 20 percent of its pre-war population.[436] Over 90 percent of the death toll came through non-military losses, through various deliberate actions by Germany and the Soviet Union.[433] Polish children were also kidnapped by Germans to be "Germanized", with perhaps as many as 200,000 children stolen from their families.[437]

The number of prisoners incarcerated in Dachau between 1933 and 1945 exceeded 188,000. The number of prisoners who died in the camp and the subcamps between January 1940 and May 1945 was at least 28,000, to which must be added those who perished there between 1933 and the end of 1939. It is unlikely that the total number of victims who died in Dachau will ever be known.
In most ghettos, Nazis ordered the Jews to establish a Judenrat (Jewish council) to administer Nazi demands and to regulate the internal life of the ghetto. The Nazis routinely ordered deportations from the ghettos. In some of the large ghettos, 1,000 people per day were sent by rail to concentration and extermination camps. To get them to cooperate, the Nazis told the Jews they were being transported elsewhere for labor.

From the evidence it became clear how this was done. After a sleepless night – for sleep in the huts was impossible – the men were driven to a hut where the dead were collected. They were instructed by what the witness called the “language of blows, which was universal.” Their duty was to take strips of blankets, tie them to a corpse, and, four men to a corpse, drag it across the main road of the camp along dusty paths to the burial pit. In the midst of this work, which lasted three days without sleep, food, or water till the British arrived, one Hungarian guard at the exit from the hut containing the bodies began shooting all prisoners if they did not come out dragging a body at the double. During the last three days the Hungarian guards were almost continuously shooting at prisoners, sometimes single shots, sometimes fusillades.

For the last four days there has been no delivery [of food] from Hannover owing to interrupted communications, and I shall be compelled, if this state of affairs prevails till the end of the week, to fetch bread also by means of truck from Hannover. The trucks allotted to the local unit are in no way adequate for this work, and I am compelled to ask for at least three to four trucks and five to six trailers. When I once have here a means of towing then I can send out the trailers into the surrounding area ... The supply question must, without fail, be cleared up in the next few days. I ask you, Gruppenführer, for an allocation of transport ...
Throughout the spring and summer of 1940, the German army expanded Hitler’s empire in Europe, conquering Denmark, Norway, the Netherlands, Belgium, Luxembourg and France. Beginning in 1941, Jews from all over the continent, as well as hundreds of thousands of European Gypsies, were transported to the Polish ghettoes. The German invasion of the Soviet Union in June 1941 marked a new level of brutality in warfare. Mobile killing units called Einsatzgruppenwould murder more than 500,000 Soviet Jews and others (usually by shooting) over the course of the German occupation.
On 15 October 1944 a train carrying 700 men on Schindler's list was initially sent to the concentration camp at Gross-Rosen, where the men spent about a week before being re-routed to the factory in Brünnlitz.[66] Three hundred female Schindlerjuden were similarly sent to Auschwitz, where they were in imminent danger of being sent to the gas chambers. Schindler's usual connections and bribes failed to obtain their release. Finally after he sent his secretary, Hilde Albrecht, with bribes of black market goods, food and diamonds, the women were sent to Brünnlitz after several harrowing weeks in Auschwitz.[67]
Between April and June of 1940, Germany invaded Norway, Denmark, the Netherlands, Belgium, and Luxembourg consolidating power across neutral Western Europe. On June 22, 1940, France signed an armistice with Germany, which divided France between the German-occupied territory in the north and the Vichy regime in the south. Although officially neutral, the French state during this time was generally pro-Nazi and cooperated with Germany’s racial policies.
In March 1933, SS leader Heinrich Himmler became chief of the Munich police and decided to establish an SS-run concentration camp at an unused munitions factory in the town of Dachau, 12 miles northwest of Munich. The first commandant, Hilmar Wäckerle, ran the place so badly that it damaged the reputation of the SS. Himmler fired him in June and chose as his replacement the fanatical SS man, Theodor Eicke.

Several thousand Catholic clergy members were also incarcerated at Dachau. One was Titus Brandsma (1881-1942), a Carmelite cleric, philosopher, writer, teacher and historian as well as an avowed anti-Nazi. Brandsma arrived at Dachau in June 1942, and died the following month after being given a lethal injection. In 1985, he was beatified by Pope John Paul II (1920 -2005). Michał Kozal (1893-1943), a Polish priest, arrived at Dachau in 1941, and for two years, he attended to the spiritual needs of his fellow prisoners. In January 1943, Kozal perished from a lethal injection. Pope John Paul II beatified him in 1987.

Medical experiments conducted on camp inmates by the SS were another distinctive feature.[51] At least 7,000 prisoners were subjected to experiments; most died as a result, during the experiments or later.[52] 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.[53] 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.[52]
Dachau is 20 km (12 mi) northwest of Munich. It is 482 meters above sea level by the river Amper, with a boundary demarcated by lateral moraines formed during the last ice age and the Amper glacial valley. It is also close to a large marshy area called Dachauer Moos. Highest elevation of the district is the so-called "Schlossberg", the lowest point is near the neighborhood of Prittlbach, at the border to the next community of Hebertshausen. The bordering communities are Bergkirchen to the west, Schwabhausen to the northwest, Röhrmoos to the north, Hebertshausen to the northeast, and Karlsfeld to the south. To the east the greater district Dachau borders on the greater district of Munich with the community of Oberschleißheim.
Dachau was the concentration camp that was in operation the longest from March 1933 to April 1945, nearly all twelve years of the Nazi regime. Dachau's close proximity to Munich, where Hitler came to power and where the Nazi Party had its official headquarters, made Dachau a convenient location. From 1933 to 1938, the prisoners were mainly German nationals detained for political reasons. After the Reichspogromnacht or Kristallnacht, 30,000 male Jewish citizens were deported to concentration camps. More than 10,000 of them were interned in Dachau alone. As the German military occupied other European states, citizens from across Europe were sent to concentration camps. Subsequently, the camp was used for prisoners of all sorts, from every nation occupied by the forces of the Third Reich.[15]:137
All the major death camps were behind the "Iron Curtain" and few Americans had even heard of them before the fall of Communism; the six death camps, Auschwitz, Majdanek, Treblinka, Sobibor, Belzec and Chelmno were all located in what is now Poland, and they were controlled by the Communists. For many years in America, Dachau was the name most associated with the Holocaust, not Auschwitz.
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:
The camp was liberated on April 15, 1945, by the British 11th Armoured Division.[4] The soldiers discovered approximately 60,000 prisoners inside, most of them half-starved and seriously ill,[5] and another 13,000 corpses, including those of Anne and Margot Frank, lying around the camp unburied.[4] The horrors of the camp, documented on film and in pictures, made the name "Belsen" emblematic of Nazi crimes in general for public opinion in many countries in the immediate post-1945 period. Today, there is a memorial with an exhibition hall at the site.
