That June, Theodor Eicke (1892-1943) replaced Wäckerle as Dachau commandant. Eicke immediately released a set of regulations for the camp’s daily operation. Prisoners deemed guilty of rule breaking were to be brutally beaten. Those who plotted to escape or espoused political views were to be executed on the spot. Prisoners would not be allowed to defend themselves or protest this treatment. Eicke’s regulations served as a blueprint for the operation of all concentration camps in Nazi Germany.
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]
To more than 1200 Jews Oscar Schindler was all that stood between them and death at the hands of the Nazis. A man full of flaws like the rest of us - the unlikeliest of all role models who started by earning millions as a war profiteer and ended by spending his last pfennig and risking his life to save his Jews. An ordinary man who even in the worst of circumstances did extraordinary things, matched by no one. He remained true to his Jews, the workers he referred to as my children. In the shadow of Auschwitz he kept the SS out and everyone alive.
Sanitation was incredibly inadequate, with few latrines and water faucets for the tens of thousands of prisoners interned in Bergen-Belsen at this time. Overcrowding, poor sanitary conditions, and the lack of adequate food, water, and shelter led to an outbreak of diseases such as typhus, tuberculosis, typhoid fever, and dysentery, causing an ever increasing number of deaths. In the first few months of 1945, tens of thousands of prisoners died.

With the invasion of the Soviet Union on June 22 1941, the Nazis launched a crusade against 'Judaeo-Bolshevism', the supposed Jewish-Communist conspiracy. Behind the front lines, four police battalions called Einsatzgruppen (operations groups) moved from town to town in the newly occupied Soviet territories, rounding up Jewish men and suspected Soviet collaborators and shooting them. In subsequent sweeps, making heavy use of local volunteers, the Einsatzgruppen targeted Jewish women and children as well. In total, the Einsaztgruppen murdered some two million people, almost all Jews.
On 23 October 1943, 1,800 of these Jews arrived in Auschwitz where they were all immediately killed. During the undressing, prior to entering the gas chambers one woman throws her clothes at SS- Scharfuhrer Schillinger grabs his revolver and shoots him three times. She also shoots SS- Unterscharfuhrer Emmerich. Reinforcements were called, some women were shot, the rest are driven into the gas chamber and killed. Schillinger died on the way to the hospital, Emmerich recovered but was crippled. 
Oskar Schindler, (born April 28, 1908, Svitavy [Zwittau], Moravia, Austria-Hungary [now in the Czech Republic]—died October 9, 1974, Hildesheim, West Germany), German industrialist who, aided by his wife and staff, sheltered approximately 1,100 Jews from the Nazis by employing them in his factories, which supplied the German army during World War II.
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]
In March 1944, part of the camp was redesignated as an Erholungslager ("recovery camp"),[11] where prisoners too sick to work were brought from other concentration camps. They were in Belsen supposedly to recover and then return to their original camps and resume work, but many of them died in Belsen of disease, starvation, exhaustion and lack of medical attention.[12]
