In June 1941 Germany attacked the Soviet Union and began the "Final Solution." Four mobile killing groups were formed called Einsatzgruppen A, B, C and D. Each group contained several commando units. The Einsatzgruppen gathered Jews town by town, marched them to huge pits dug earlier, stripped them, lined them up, and shot them with automatic weapons. The dead and dying would fall into the pits to be buried in mass graves. In the infamous Babi Yar massacre, near Kiev, 30,000-35,000 Jews were killed in two days. In addition to their operations in the Soviet Union, the Einsatzgruppen conducted mass murder in eastern Poland, Estonia, Lithuania and Latvia. It is estimated that by the end of 1942, the Einsatzgruppen had murdered more than 1.3 million Jews.
You see, when Bergen-Belsen was liberated these people were let loose. So we were wandering. We were wandering from one place to another. And there were warehouses. We came to a building, and we walked in, and I still see rows and rows and shelves of handbags, ladies' handbags. As we were walking over there to reach those shelves, I sort of stepped on something. And I said to my friend, "Look! There's a body!" You see, somebody, one of these inmates who wandered to these warehouses and dropped dead from exhaustion or something. And she says, "What do you want me to do about it?" I said, "Let's carry it out." She said, "Are you crazy? You can't carry that out." and she took a few packages of these linens and dropped it on (the body). And then we went to the shelves, and she wanted a handbag. And I wasn't in the mood anymore for the handbag. She pulled out one handbag. It was an alligator handbag. She says, "Take this one." I took it, and she took another one, and we walked out. And I remember, as we left the place, I just threw back the bag. I said, "I don't want it." - and walked away. And this only came back. I never thought about it.
Throughout the 1930s, the legal, economic, and social rights of Jews were steadily restricted.[83] On 1 April 1933, there was a boycott of Jewish businesses.[84] On 7 April 1933, the Law for the Restoration of the Professional Civil Service was passed, which excluded Jews and other "non-Aryans" from the civil service.[85] Jews were disbarred from practising law, being editors or proprietors of newspapers, joining the Journalists' Association, or owning farms.[86] In Silesia, in March 1933, a group of men entered the courthouse and beat up Jewish lawyers; Friedländer writes that, in Dresden, Jewish lawyers and judges were dragged out of courtrooms during trials.[87] Jewish students were restricted by quotas from attending schools and universities.[85] Jewish businesses were targeted for closure or "Aryanization", the forcible sale to Germans; of the approximately 50,000 Jewish-owned businesses in Germany in 1933, about 7,000 were still Jewish-owned in April 1939. Works by Jewish composers,[88] authors, and artists were excluded from publications, performances, and exhibitions.[89] Jewish doctors were dismissed or urged to resign. The Deutsches Ärzteblatt (a medical journal) reported on 6 April 1933: "Germans are to be treated by Germans only."[90]
In anticipation of such violence against the Jews by the Nazis, President Franklin D. Roosevelt had invited 32 countries to a Conference in Evian, France in July 1938 to discuss the problem of Jewish refugees. The only country which agreed to allow Jewish refugees as immigrants was the Dominican Republic; 5,000 German Jews emigrated to the Dominican Republic before the start of World War II. The American Congress refused to change the US immigration laws, passed in 1920 and 1921, to allow a higher quota of Jewish refugees from Germany to enter, although America did start filling the quota under the existing laws for the first time.
Most of the regular SS guards and the administrative staff had fled from the camp the next day and there was no one left to oversee the burial of the bodies. No precise figures are available, but the train had started out with approximately 4,500 to 6,000 prisoners on board and between 1,300 and 2,600 had made it to Dachau still alive. Some of the dead had been buried along the way, or left in rows alongside the tracks. The gruesome sight of the death train, with some of the corpses in the open cars riddled by bullets, so affected the young soldiers of the 45th Thunderbird Division that they executed Waffen-SS soldiers stationed at the Dachau garrison after they had surrendered.
Deputy Fritz Dressel underwent similar daily tortures. He tried to cut his wrist with a piece of glass, but he was discovered while he still showed some signs of life and was transferred to a first-aid station. No sooner was his wound dressed than the Camp Commander, Weckerle, ordered him brought back into the detention call, in spite of the doctor’s warning that under these circumstances he would not be responsible for the consequences. A few hours later he was again “discovered” with the dressing ripped off, lying in a pool of blood, his arms pulled out of their sockets.  When his corpse was taken out of the camp on a dray, the Commander made a remark to the assembled Special Police, which unfortunately I could not understand, but which was answered by the guards with roars of laughter. Captain Ehmann of the Special Police and another man led Leonhart Hausmann, Communist leader of Augsburg, out of the camp to be shot. Ehmann, however, lost his courage and ran away and the other fellow brought the prisoner back. The next day Hausmann was transferred to Ehmann’s labor group, and Ehmann took him out of sight behind some bushes and shot him. The official announcement was “Shot while trying to escape.” Ehmann was apparently reluctant to murder the prisoner, but was finally forced to do so by pressure from his superiors.
The most famous American at Dachau was Rene Guiraud. After being given intensive specialized training, Lt. Guiraud was parachuted into Nazi-occupied France, along with a radio operator. His mission was to collect intelligence, harass German military units and occupation forces, sabotage critical war material facilities, and carry on other resistance activities. Guiraud organized 1500 guerrilla fighters and developed intelligence networks. During all this, Guiraud posed as a French citizen, wearing civilian clothing. He was captured and interrogated for two months by the Gestapo, but revealed nothing about his mission. After that, he was sent to Dachau where he participated in the camp resistance movement along with the captured British spies. Two weeks after the liberation of the camp, he "escaped" from the quarantined camp and went to Paris where he arrived in time to celebrate V-E day.
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.

In the view of Christian Gerlach, Hitler announced his decision to annihilate the Jews on or around 12 December 1941, probably on 12 December during a speech to the Gauleiters, part of the Nazi Party leadership.[259] This was one day after the German declaration of war against the United States, which followed the Japanese attack on Pearl Harbour on 7 December and the United States declaration of war on Japan on 8 December.[260] According to Deborah Dwork and Robert Jan van Pelt, Hitler had trusted American Jews, whom he assumed were all-powerful, to keep their government out of the war in the interests of German Jews. When America declared war, the Jews were blamed.[261] Joseph Goebbels, the Reich Minister of Propaganda, noted of Hitler's speech: "He warned the Jews that if they were to cause another world war, it would lead to their destruction. ... Now the world war has come. The destruction of the Jews must be its necessary consequence."[260][o]

The Dachau concentration camp opened on March 22, 1933. It was the first SS-run camp for "political prisoners" under Hitler's regime and became a model for the many SS prison camps that followed. Located in southern Germany, Dachau remained open until 1945 when it was liberated by U.S. troops. Approximately 200,000 people were detained during these years and an estimated 41,500 died.

On January 20, 1942, Reinhard Heydrich convened the Wannsee Conference at a lakeside villa in Berlin to organize the “final solution to the Jewish question.” Around the table were 15 men representing government agencies necessary to implement so bold and sweeping a policy. The language of the meeting was clear, but the meeting notes were circumspect:

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]
David M. Crowe’s book Oskar Schindler: The Untold Account of His Life, Wartime Activities and the True Story Behind The List should be considered a classic in investigative and historical research. Based on interviews with dozens of Holocaust survivors saved by Oskar Schindler and with access to documents unavailable to Schindler’s List author Thomas Keneally, Crowe sheds light on one of the most dramatic and important stories to come out of World War II.
Over the next days the surviving prisoners were deloused and moved to a nearby German Panzer army camp, which became the Bergen-Belsen DP (displaced persons) camp. Over a period of four weeks, almost 29,000 of the survivors were moved there. Before the handover, the SS had managed to destroy the camp's administrative files, thereby eradicating most written evidence.[21]

Dachau was liberated by American troops on April 29, 1945. Among their most-gruesome discoveries were railroad cars filled with Jewish prisoners who had died en route to the camp and had been left to decompose. American and British media coverage of Dachau and other newly liberated camps—which included photographs published in magazines and newsreel footage shown in cinemas—profoundly shaped the public’s understanding of the atrocities that had occurred.
The Roma refer to the genocide of the Romani people as the Pořajmos.[414] Because they are traditionally a private people with a culture based on oral history, less is known about their experience than that of any other group.[415] Bauer writes that this can be attributed to the Roma's distrust and suspicion, and to their humiliation because some of the taboos in Romani culture regarding hygiene and sex were violated at Auschwitz.[416] In May 1942, the Roma were placed under similar laws to the Jews. On 16 December 1942, Himmler issued a decree that "Gypsy Mischlinge [mixed breeds], Roma Gypsies, and members of the clans of Balkan origins who are not of German blood" should be sent to Auschwitz, unless they had served in the Wehrmacht.[417] He adjusted the order on 15 November 1943; in the occupied Soviet areas, "sedentary Gypsies and part-Gypsies are to be treated as citizens of the country. Nomadic Gypsies and part-Gypsies are to be placed on the same level as Jews and placed in concentration camps."[418] Bauer argues that this adjustment reflected Nazi ideology that the Roma, originally an Aryan population, had been "spoiled" by non-Romani blood.[419]
Nolte's views were widely denounced. The debate between the "specifists" and "universalists" was acrimonious; the former feared debasement of the Holocaust and the latter considered it immoral to hold the Holocaust as beyond compare.[478] In her book Denying the Holocaust (1993), Deborah Lipstadt viewed Nolte's position as a form of Holocaust denial, or at least "the same triumph of ideology over truth".[479] Addressing Nolte's argument, Eberhard Jäckel wrote in Die Zeit in September 1986 that "never before had a state, with the authority of its leader, decided and announced that a specific group of humans, including the elderly, women, children and infants, would be killed as quickly as possible, then carried out this resolution using every possible means of state power".[h] Despite the criticism of Nolte, Dan Stone wrote in 2010 that the Historikerstreit put "the question of comparison" on the agenda.[480] He argued that the idea of the Holocaust as unique has been overtaken by attempts to place it within the context of early-20th-century Stalinism, ethnic cleansing, and the Nazis' intentions for post-war "demographic reordering", particularly the Generalplan Ost, the plan to kill tens of millions of Slavs to create living space for Germans.[481] The specifist position continued nevertheless to inform the views of many specialists. Richard J. Evans argued in 2015:
Dachau was the place where many famous, high-level political opponents of the Nazi government were held near the end of the war. Just before the camp was liberated, there were 137 VIP prisoners at Dachau, including the former Chancellor of Austria, Kurt von Schuschnigg, and the former Jewish premier of France, Leon Blum. They were evacuated to the South Tyrol in April 1945 on three separate trips, shortly before soldiers of the American Seventh Army arrived to liberate the camp.
Beginning in 1943, a series of 123 sub-camps were set up near the Dachau main camp. The worst of these sub-camps were the 11 camps near Landsberg am Lech, which were named Kaufering I - XI; Kaufering was the name of the railroad station where the prisoners arrived by train. Beginning on June 18, 1944, Hungarian Jews from the death camp at Auschwitz-Birkenau were brought to the Kaufering camps to work on construction of underground factories where airplanes were to be built.

Political dissidents, trade unionists, and Social Democrats were among the first to be arrested and incarcerated in concentration camps. Under the Weimar government, centuries-old prohibitions against homosexuality had been overlooked, but this tolerance ended violently when the SA (Storm Troopers) began raiding gay bars in 1933. Homosexual intent became just cause for prosecution. The Nazis arrested German and Austrian male homosexuals—there was no systematic persecution of lesbians—and interned them in concentration camps, where they were forced to wear special yellow armbands and later pink triangles. The goal of persecuting male homosexuals was either for reeducation—what might now be called conversion therapy—or punishment. Jehovah’s Witnesses were a problem for the Nazis because they refused to swear allegiance to the state, register for the draft, or utter the words “Heil Hitler.” As a result, the Nazis imprisoned many of the roughly 20,000 Jehovah’s Witnesses in Germany. They could be released from concentration camps if they signed a document renouncing their faith and promising not to proselytize. Few availed themselves of that option, preferring martyrdom to apostasy. Germans of African descent—many of whom, called “Rhineland bastards” by the Nazis, were the offspring of German mothers and French colonial African troops who had occupied the Rhineland after World War I—were also persecuted by the Nazis. Although their victimization was less systematic, it included forced sterilization and, often, internment in concentration camps. The fear was that they would “further pollute” and thereby diminish the race. The Nazis also singled out the Roma and Sinti, pejoratively known as Gypsies. They were the only other group that the Nazis systematically killed in gas chambers alongside the Jews. For the Roma and Sinti, too, racial pollution and their depiction as asocials was the justification for their persecution and murder.
Defined by the religion of their grandparents rather than by their own beliefs, Jews were viewed as having impure blood lines. The new laws were taught in schools, cementing anti-Semitism in German culture. Most Germans kept quiet, often benefiting when Jews lost jobs and businesses. Persecution of other minorities also escalated: the police were given new powers to arrest homosexuals and compulsory abortions were administered to women considered to be ‘hereditarily ill’.
Under such terrible conditions, Kramer did everything in his power to reduce suffering and prevent death among the inmates, even appealing to the hard-pressed German army. "I don't know what else to do," he told high-ranking army officers. "I have reached the limit. Masses of people are dying. The drinking water supply has broken down. A trainload of food was destroyed by low-flying [Allied] war planes. Something must be done immediately." /16
New arrivals at Dachau were never told how long they would be imprisoned, a factor that weakened their morale and left them more vulnerable to the remolding that would follow. Often, their journey to Dachau marked the first time they had ever been arrested or involved with police. Many had been sent there by the Gestapo upon vague accusations or denunciations by persons who simply disliked them or who wanted to settle an old score. Some were even arrested on suspicion they might commit a crime in the future.
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.
Ghettos were intended to be temporary until the Jews were deported to other locations, which never happened. Instead, the inhabitants were sent to extermination camps. The ghettos were, in effect, immensely crowded prisons serving as instruments of "slow, passive murder."[216] Though the Warsaw Ghetto contained 30% of Warsaw's population, it occupied only 2.5% of the city's area, averaging over 9 people per room.[217] Between 1940 and 1942, starvation and disease, especially typhoid, killed many in the ghettos.[218] Over 43,000 Warsaw ghetto residents, or one in ten of the total population, died in 1941;[219] in Theresienstadt, more than half the residents died in 1942.[216]
50,000 prisoners died in Bergen-Belsen. 60,000 prisoners were liberated by the Allies in April, 1945. The Bergen-Belsen staff, largely intact at the time of liberation, were tried in 1945 by a British military tribunal in Luneburg, Germany. Among those tried were the camp Kommandant, Josef Kramer, and a 22-year old female S.S. guard, Irma Grese, who was accused by camp inmates of shooting prisoners and beating them with a homemade whip. Forty-five staff were tried; fourteen were acquitted.
In the fall of that year the Płaszów work camp opened nearby, and by February 1943 it was under the command of the notoriously sadistic SS officer Amon Göth, who would be executed after the war. Capitalizing on the officer’s appetite for drink and other luxury items available mainly on the black market, Schindler cultivated his friendship by ensuring a constant stream of them to the villa from which he oversaw the camp. Schindler thus managed to prevail upon Göth to create a separate camp for his Jewish workers, where they were free of the abuses suffered at Płaszów. Though Schindler’s motivations prior to this point are unclear, many scholars interpret his efforts to extricate his workers from Płaszów as indication that his concern for them was not purely financial.
"The fact is that all these were once clean-living and sane and certainly not the type to do harm to the Nazis. They are Jews and are dying now at the rate of three hundred a day. They must die and nothing can save them --their end is inescapable, they are too far gone now to be brought back to life. I saw their corpses lying near their hovels, for they crawl or totter out into the sunlight to die. I watched them make their last feeble journeys, and even as I watched they died."
Over a short period of time, Bergen Belsen became the largest DP camp in Germany. In 1946, more than 11,000 Jews lived there. Some survivors succumbed to their despair in the DP camp. After years of forced labor, some survivors refused to work at all. Others developed a Black Market at Bergen Belsen, trafficking in anything that would earn them a penny. However, the majority of survivors at Bergen Belsen were able to gather emotional energy and channel it towards rebuilding their lives.
Few visitors to the camp bother to visit the town of Dachau which has grown from 13,000 residents in 1945 to 50,000 residents. Dachau is now multicultural and has a diverse population which includes many people who are not ethnic German. Older residents of Dachau are quick to point out that the majority of the people in the town did not vote for Hitler when he ran for President of Germany in 1932.
Schindler first arrived in Kraków in October 1939, on Abwehr business, and took an apartment the following month. Emilie maintained the apartment in Ostrava and visited Oskar in Kraków at least once a week.[18][19] In November 1939, he contacted interior decorator Mila Pfefferberg to decorate his new apartment. Her son, Leopold "Poldek" Pfefferberg, soon became one of his contacts for black market trading. They eventually became lifelong friends.[20]

In December 1944 SS-Hauptsturmführer Josef Kramer, previously at Auschwitz-Birkenau, became the new camp commandant, replacing SS-Hauptsturmführer Adolf Haas [de], who had been in post since the spring of 1943.[7] In January 1945, the SS took over the POW hospital and increased the size of Bergen-Belsen. As eastern concentration camps were evacuated before the advance of the Red Army, at least 85,000 people were transported in cattle cars or marched to Bergen-Belsen.[14] Before that the number of prisoners at Belsen had been much smaller. In July 1944 there were 7,300; by December 1944 the number had increased to 15,000; and by February 1945 it had risen to 22,000. Numbers then soared to around 60,000 by April 15, 1945.[7] This overcrowding led to a vast increase in deaths from disease: particularly typhus, as well as tuberculosis, typhoid fever, dysentery and malnutrition in a camp originally designed to hold about 10,000 inmates. At this point also, the special status of the exchange prisoners no longer applied. All inmates were subject to starvation and epidemics.[14]
