A book entitled "Dachau Liberated, The Official Report by the U.S. Seventh Army" was released only days after the camp was liberated. The information in this book was obtained from interviews with the Dachau survivors; half of the prisoners at Dachau on the day it was liberated had only been there for two weeks or less and some had arrived only the day before. The following quote is from page 48 of this book:
Another former inmate, Moshe Peer, recalled a miraculous escape from death as an eleven-year-old in the camp. In a 1993 interview with a Canadian newspaper, the French-born Peer claimed that he "was sent to the [Belsen] camp gas chamber at least six times." The newspaper account went on to relate: "Each time he survived, watching with horror as many of the women and children gassed with him collapsed and died. To this day, Peer doesn't know how he was able to survive." In an effort to explain the miracle, Peer mused: "Maybe children resist better, I don't know." (Although Peer claimed that "Bergen-Belsen was worse than Auschwitz," he acknowledged that he and his younger brother and sister, who were deported to the camp in 1944, all somehow survived internment there.) /37
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 Jews killed represented around one third of the world population of Jews,[398] and about two-thirds of European Jewry, based on an estimate of 9.7 million Jews in Europe at the start of the war.[399] Much of the uncertainty stems from the lack of a reliable figure for the number of Jews in Europe in 1939, numerous border changes that make avoiding double-counting of victims difficult, lack of accurate records from the perpetrators, and uncertainty about whether deaths occurring months after liberation, but caused by the persecution, should be counted.[392]
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]
Between the years 1933 and 1945, more than 3.5 million Germans were imprisoned in such concentration camps or prison for political reasons.[49][50][51] Approximately 77,000 Germans were killed for one or another form of resistance by Special Courts, courts-martial, and the civil justice system. Many of these Germans had served in government, the military, or in civil positions, which were considered to enable them to engage in subversion and conspiracy against the Nazis.[52]

My father supervised work parties in which Irma Grese was forced to carry corpses for burial and he described her as really beautiful but utterly evil. Most of the SS guards were evil and Dad had trouble stopping his men from shooting them out of hand, especially when the SS prisoners protested about having to work in burial details. He was tempted to do so himself. He told me that Bergen-Belsen brought home to him what they had been fighting, evil from the pit of hell itself.
The camp at Dachau is one of the first and largest concentration camps in Germany. The area, comprising about one square mile, is enclosed by a concrete wall seven feet high and covered with barbed wire. In the southwestern corner there are thirteen crude barracks, originally built for military purposes. They are in a dilapidated condition because of sixteen years of weathering, and were only superficially restored to serve as a shelter for 1,800 Bavarian workmen, political adversaries of the new regime.
Also in 1993, the United States Holocaust Memorial Council posthumously presented the Museum's Medal of Remembrance to Schindler. Rarely presented, this medal honors deserving recipients for extraordinary deeds during the Holocaust and in the cause of Remembrance. Emilie Schindler accepted the medal on behalf of her ex-husband at a ceremony in the Museum's Hall of Remembrance.
Hitler’s worldview revolved around two concepts: territorial expansion (that is, greater Lebensraum—“living space”—for the German people) and racial supremacy. After World War I the Allies denied Germany colonies in Africa, so Hitler sought to expand German territory and secure food and resources—scarce during World War I—in Europe itself. Hitler viewed the Jews as racial polluters, a cancer on German society in what has been termed by Holocaust survivor and historian Saul Friedländer “redemptive anti-Semitism,” focused on redeeming Germany from its ills and ridding it of a cancer on the body politic. Historian Timothy Snyder characterized the struggle as even more elemental, as “zoological,” and “ecological,” a struggle of the species. Hitler opposed Jews for the values they brought into the world. Social justice and compassionate assistance to the weak stood in the way of what he perceived as the natural order, in which the powerful exercise unrestrained power. In Hitler’s view, such restraint on the exercise of power would inevitably lead to the weakening, even the defeat, of the master race.
Some of the inmates were exempt from work because they were too old or too young, but a few of the older prisoners worked on the herb farm. According to Paul Berben, "Statistics made by the camp administration on 16th February 1945 list 2,309 men and 44 women aged between 50 and 60 and 5,465 men and 12 women over 60." These figures are for the main camp at Dachau and all the subcamps.
In January 1945 a trainload of 250 Jews who had been rejected as workers at a mine in Goleschau in Poland arrived at Brünnlitz. The boxcars were frozen shut when they arrived, and Emilie Schindler waited while an engineer from the factory opened the cars using a soldering iron. Twelve people were dead in the cars, and the remainder were too ill and feeble to work. Emilie took the survivors into the factory and cared for them in a makeshift hospital until the end of the war.[74][73] Schindler continued to bribe SS officials to prevent the slaughter of his workers as the Red Army approached.[75] On 7 May 1945 he and his workers gathered on the factory floor to listen to British Prime Minister Winston Churchill announce over the radio that Germany had surrendered, and the war in Europe was over.[76]
Behind the furnace was the execution chamber, a windowless cell twenty feet square with gas nozzles every few feet across the ceiling. Outside, in addition to the huge mound of charred bone fragments, were the carefully sorted and stacked clothes of the victims - which obviously numbered in the thousands. Although I stood there looking at it, I couldn't believe it. The realness of the whole mess is just gradually dawning on me, and I doubt if it will ever on you.

During the era of the Holocaust, German authorities also targeted other groups because of their perceived racial and biological inferiority: Roma (Gypsies), people with disabilities, and some of the Slavic peoples (Poles, Russians, and others). Other groups were persecuted on political, ideological, and behavioral grounds, among them Communists, Socialists, Jehovah's Witnesses, and homosexuals.
The camp administration did nothing to house the prisoners who were streaming in. Most of them had no roof over their heads, and were without water and food. There was now total chaos in Bergen- Belsen and a typhus epidemic broke out, in the month of March alone 18,168 prisoners perished in the camp and the number of deaths for the period from January to mid-April 1945 was 35,000.
The Polish government-in-exile in London learned about the extermination camps from the Polish leadership in Warsaw, who from 1940 "received a continual flow of information about Auschwitz", according to historian Michael Fleming.[333] This was in large measure thanks to Captain Witold Pilecki of the Polish Home Army, who allowed himself to be arrested in Warsaw and spent 945 days in Auschwitz from September 1940 until April 1943, organizing the resistance movement inside the camp.[334]
Man blinded by continuous beatings  © The ideas and emotions that lay behind the Holocaust were not new, nor were they uniquely German. The Nazis were the heirs of a centuries-old tradition of Jew-hatred, rooted in religious rivalry and found in all European countries. When the Nazis came to carry out their genocidal programme, they found collaborators in all the countries they dominated, including governments that enjoyed considerable public support. Most people drew the line at mass murder, but relatively few could be found to oppose it actively or to extend help to the Jews.
The Holocaust was the murder by Nazi Germany of six million Jews. While the Nazi persecution of the Jews began in 1933, the mass murder was committed during World War II. It took the Germans and their accomplices four and a half years to murder six million Jews. They were at their most efficient from April to November 1942 – 250 days in which they murdered some two and a half million Jews. They never showed any restraint, they slowed down only when they began to run out of Jews to kill, and they only stopped when the Allies defeated them. More...
Current estimates put the number of prisoners who passed through the concentration camp during its period of operation from 1943 to 1945 at around 120,000. Due to the destruction of the camp's files by the SS, not even half of them, around 55,000, are known by name.[10]:269 As mentioned above, treatment of prisoners by the SS varied between individual sections of the camp, with the inmates of the exchange camp generally being better treated than other prisoners, at least initially. However, in October 1943 the SS selected 1,800 men and women from the Sonderlager ("special camp"), Jews from Poland who held passports from Latin American countries. Since the governments of these nations mostly refused to honour the passports, these people had lost their value to the regime. Under the pretext of sending them to a fictitious "Lager Bergau", the SS had them transported to Auschwitz-Birkenau, where they were sent directly to the gas chambers and killed. In February and May 1944 another 350 prisoners from the "special camp" were sent to Auschwitz. Thus, out of the total of 14,600 prisoners in the exchange camp, at least 3,550 died, more than 1,400 of them at Belsen, and around 2,150 at Auschwitz.[10]:187
