At Auschwitz, after the chambers were filled, the doors were shut and pellets of Zyklon-B were dropped into the chambers through vents,[293] releasing toxic prussic acid, or hydrogen cyanide.[294] Those inside died within 20 minutes; the speed of death depended on how close the inmate was standing to a gas vent, according to the commandant Rudolf Höss, who estimated that about one-third of the victims died immediately.[295] Johann Kremer, an SS doctor who oversaw the gassings, testified that: "Shouting and screaming of the victims could be heard through the opening and it was clear that they fought for their lives."[296] The gas was then pumped out, the bodies were removed, gold fillings in their teeth were extracted, and women's hair was cut.[297] The work was done by the Sonderkommando, work groups of mostly Jewish prisoners.[298] At Auschwitz, the bodies were at first buried in deep pits and covered with lime, but between September and November 1942, on the orders of Himmler, they were dug up and burned. In early 1943, new gas chambers and crematoria were built to accommodate the numbers.[299]
Death: Dr. Miklos Nyiszli was Mengele's prisoner pathologist. The autopsies became the final experiment. Nyiszli performed autopsies on twins who had died from the experiments or who had been purposely killed just for after-death measurements and examination. Some of the twins had been stabbed with a needle that pierced their heart and then was injected with chloroform or phenol, which caused near immediate blood coagulation and death. Some of the organs, eyes, blood samples and tissues would be sent to Verschuer for further study.
Astonishingly, the Nazified notion of “race” leaped out in a line attributed to Hellman and nowhere present in the diary. “We’re not the only people that’ve had to suffer,” the Hacketts’ Anne says. “There’ve always been people that’ve had to . . . sometimes one race . . . sometimes another.” This pallid speech, yawning with vagueness, was conspicuously opposed to the pivotal reflection it was designed to betray:
In 1942, with the Nazis occupying Holland, a thirteen-year-old Jewish girl and her family fled their home in Amsterdam and went into hiding. For the next two years, until their whereabouts were betrayed to the Gestapo, the Franks and another family lived cloistered in the “Secret Annexe” of an old office building. Cut off from the outside world, they faced hunger, boredom, the constant cruelties of living in confined quarters, and the ever-present threat of discovery and death. In her diary Anne Frank recorded vivid impressions of her experiences during this period. By turns thoughtful, moving, and surprisingly humorous, her account offers a fascinating commentary on human courage and frailty and a compelling self-portrait of a sensitive and spirited young woman whose promise was tragically cut short.

But throughout Nazi-occupied Europe, relatively few non-Jewish persons were willing to risk their own lives to help the Jews. Notable exceptions included Oskar Schindler, a German who saved 1200 Jews by moving them from Plaszow labor camp to his hometown of Brunnlitz. The country of Denmark rescued nearly its entire population of Jews, over 7000, by transporting them to safety by sea. Italy and Bulgaria both refused to cooperate with German demands for deportations. Elsewhere in Europe, people generally stood by passively and watched as Jewish families were marched through the streets toward waiting trains, or in some cases, actively participated in Nazi persecutions.

"... Believe me, I'd like to listen, but it doesn't work, because if I'm quiet and serious, everyone thinks I'm putting on a new act and I have to save myself with a joke, and then I'm not even talking about my own family, who assume I must be ill, stuff me with aspirins and sedatives, feel my neck and forehead to see if I have a temperature, ask about my bowel movements and berate me for being in a bad mood, until I just can't keep it up any more, because when everybody starts hovering over me, I get cross, then sad, and finally end up turning my heart inside out, the bad part on the outside and the good part on the inside, and keep trying to find a way to become what I'd like to be and what I could be if ... if only there were no other people in the world."
I suffered from all these symptoms, together with a tight feeling at the throat. I was half conscious when my number was called out by Dr. Mengele and I was led from the chamber. I attribute my escape to the fact that the daughter of a friend of mine who was an Aryan and a doctor at Auschwitz had seen me being transported to the chamber and had told her mother, who immediately appealed to Dr. Mengele.
Heinrich Himmler witnessed this killing process and decided to develop a cheaper, more effective method of murder that would not be as upsetting for the perpetrators. The Nazis were already using gas to murder the mentally and physically disabled; this was now to be applied to the Jews as well. This section will discuss the the Wannsee Conference and the ‘Final Solution to the Jewish Question’.

If only Anne Frank's diary was the figment of someone's imagination. If it meant that this spirited, intelligent and articulate girl hadn't died along with so many others in Belsen concentration camp, and that the holocaust had never happened, that would be a wonderful thing, but it did happen, and that makes the reading of this diary even more heartbreaking.

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]
On July 5, 1942, Anne's older sister Margot received an official summons to report to a Nazi work camp in Germany, and on July 6, Margot and Anne went into hiding with their father Otto and mother Edith. They were joined by Hermann van Pels, Otto's business partner, including his wife Auguste and their teenage son Peter.[12] Their hiding place was in the sealed-off upper rooms of the annex at the back of Otto's company building in Amsterdam.[12][13] Otto Frank started his business, named Opekta, in 1933. He was licensed to manufacture and sell pectin, a substance used to make jam. He stopped running his business while everybody was in hiding. But once he returned, he found his employees running it. The rooms that everyone hid in were concealed behind a movable bookcase in the same building as Opekta. Mrs. van Pels's dentist, Fritz Pfeffer, joined them four months later. In the published version, names were changed: The van Pelses are known as the Van Daans, and Fritz Pfeffer as Albert Dussel. With the assistance of a group of Otto Frank's trusted colleagues, they remained hidden for two years and one month.

Browning also notes that the destruction of the Jews went hand-in-hand with a much wider attempt at “ethnic cleansing” throughout Eastern Europe. The Nazis had well-advanced plans, which might have been realized had they won the war, to remove by force millions of Poles and other Slavs to Siberia, with vast numbers certain to die en route. One of the major merits of Browning’s book is its detailed discussion of these plans, as well as Nazi policies towards the gypsies. Browning notes, correctly, that the Nazis killed large numbers of gypsies even though Hitler hardly ever mentioned them and certainly did not have anti-gypsy hostility at the heart of his ideology. Browning also offers a detailed consideration of the Nazi program of murdering the physically and mentally handicapped among “Aryan” Germans (the “T4 program”), which began in mid-1939 and eventually claimed seventy thousand victims before it was stopped in mid-1941, and he reports that many of the killers in the T4 program went on to be directly involved with the extermination of the Jews in Eastern Europe.
Known as Kristallnacht (or "Night of Broken Glass"), the attacks were partly carried out by the SS and SA,[122] but ordinary Germans joined in; in some areas, the violence began before the SS or SA arrived.[123] Over 7,500 Jewish shops (out of 9,000) were looted and attacked, and over 1,000 synagogues damaged or destroyed. Groups of Jews were forced by the crowd to watch their synagogues burn; in Bensheim they were forced to dance around it, and in Laupheim to kneel before it.[124] At least 90 Jews died. The damage was estimated at 39 million Reichmarks.[125] Cesarani writes that "[t]he extent of the desolation stunned the population and rocked the regime."[120] Thirty-thousand Jews were sent to the Dachau, Buchenwald and Sachsenhausen concentration camps.[126] Many were released within weeks; by early 1939, 2,000 remained in the camps.[127] German Jewry was held collectively responsible for restitution of the damage; they also had to pay an "atonement tax" of over a billion Reichmarks. Insurance payments for damage to their property were confiscated by the government. A decree on 12 November 1938 barred Jews from most of the remaining occupations they had been allowed to hold.[128] Kristallnacht marked the end of any sort of public Jewish activity and culture, and Jews stepped up their efforts to leave the country.[129]

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]
The Summer Olympics in Berlin gave the Nazis a platform to project a crafted image to the world. Despite calls for boycotts, the games were a success. Anti-Jewish notices were removed and German spectators cheered black athlete Jesse Owens to four gold medals. Visitors saw a tolerant Reich. However, three days after the games ended, the head of the Olympic Village, Wolfgang Fürstner, killed himself as he would soon be dismissed due to his Jewish ancestry under the Nuremberg Laws.

In the last months of Hitler’s Reich, as the German armies retreated, the Nazis began marching the prisoners still alive in the concentration camps to the territory they still controlled. The Germans forced the starving and sick Jews to walk hundreds of miles. Most died or were shot along the way. About a quarter of a million Jews died on the death marches.
The men selected April 15, the darkest night of the month, for the escape. Dogim, the unofficial leader of the group, was first—once he emerged from the tunnel, he would cut a hole in the nearby fence and mark it with a white cloth, so the others would know which direction to run. Farber was second. Motke Zeidel was sixth. The prisoners knew that a group of partisan fighters were holed up nearby, in the Rudnitsky Woods, in a secret camp from which they launched attacks on the Nazi occupiers. “Remember, there is no going back under any circumstances,” Farber reminded his friends. “It is better to die fighting, so just keep moving forward.”
German communists, socialists and trade unionists were among the earliest opponents of the Nazis[443] and among the first to be sent to concentration camps.[444] Before the invasion of the Soviet Union, Hitler issued the Commissar Order, which ordered the execution of all political commissars and Communist Party members captured.[445] Nacht und Nebel ("Night and Fog") was a directive of Hitler in December 1941, resulting in the disappearance of political activists throughout the German-occupied territories.[446]
After obtaining a copy of his birth certificate through the West German embassy in 1956, Mengele was issued with an Argentine foreign residence permit under his real name. He used this document to obtain a West German passport, also using his real name, and embarked on a trip to Europe.[71][72] He met up with his son Rolf (who was told Mengele was his "Uncle Fritz")[73] and his widowed sister-in-law Martha, for a ski holiday in Switzerland; he also spent a week in his home town of Günzburg.[74][75] When he returned to Argentina in September 1956, Mengele began living under his real name. Martha and her son Karl Heinz followed about a month later, and the three began living together. Josef and Martha were married in 1958 while on holiday in Uruguay, and they bought a house in Buenos Aires.[71][76] Mengele's business interests now included part ownership of Fadro Farm, a pharmaceutical company.[74] Along with several other doctors, Mengele was questioned in 1958 on suspicion of practicing medicine without a license when a teenage girl died after an abortion, but he was released without charge. Aware that the publicity would lead to his Nazi background and wartime activities being discovered, he took an extended business trip to Paraguay and was granted citizenship there in 1959 under the name "José Mengele".[77] He returned to Buenos Aires several times to settle his business affairs and visit his family. Martha and Karl lived in a boarding house in the city until December 1960, when they returned to Germany.[78]
