Of the 430,000 sent to the first death camp at Bełżec in Poland, there were only two survivors. 700,000 were killed at Treblinka in just five months. In July, Himmler ordered that all Jews in key areas of Poland, except for those needed for essential labour, were to be killed by the end of the year. Most were. Despite Allied intelligence receiving detailed reports of the mass murders in Europe, the public reaction in Britain was largely a mixture of apathy and disbelief.

Like the network of concentration camps that followed, becoming the killing grounds of the Holocaust, Dachau was under the control of Heinrich Himmler, head of the elite Nazi guard, the Schutzstaffel (SS), and later chief of the German police. By July 1933, German concentration camps (Konzentrationslager in German, or KZ) held some 27,000 people in “protective custody.” Huge Nazi rallies and symbolic acts such as the public burning of books by Jews, Communists, liberals and foreigners helped drive home the desired message of party strength.

“With respect of the Jewish Question, the Führer has decided to make a clean sweep. He prophesied to the Jews that if they again brought about a world war, they would live to see their annihilation in it. That wasn’t just a catchword… If the German people have now again sacrificed 160,000 dead on the eastern front, then those responsible for this bloody conflict will have to pay with their lives.”

The superior race was the "Aryans," the Germans. The word Aryan, "derived from the study of linguistics, which started in the eighteenth century and at some point determined that the Indo-Germanic (also known as Aryan) languages were superior in their structures, variety, and vocabulary to the Semitic languages that had evolved in the Near East. This judgment led to a certain conjecture about the character of the peoples who spoke these languages; the conclusion was that the 'Aryan' peoples were likewise superior to the 'Semitic' ones" (Leni Yahil, The Holocaust: The Fate of European Jewry, New York: Oxford University Press, 1990, p. 36).
By late January, roughly 80 prisoners, known to historians as the Burning Brigade, were living in the camp, in a subterranean wood-walled bunker they’d built themselves. Four were women, who washed laundry in large metal vats and prepared meals, typically a chunk of ice and dirt and potato melted down to stew. The men were divided into groups. The weaker men maintained the pyres that smoldered through the night, filling the air with the heavy smell of burning flesh. The strongest hauled bodies from the earth with bent and hooked iron poles. One prisoner, a Russian named Yuri Farber, later recalled that they could identify the year of death based on the corpse’s level of undress:

Of the children involved, only about 200 were alive when the camp was liberated by the Soviet Army on January 27, 1945. These are the children shown so often in documentaries walking between the wires of the Auschwitz I camp. Today they reside all over the world and they seek information on what was done to them. Their files have never been located and what was done to them remains a mystery today.

Anne Frank escaped gassing. One month before liberation, not yet sixteen, she died of typhus fever, an acute infectious disease carried by lice. The precise date of her death has never been determined. She and her sister, Margot, were among three thousand six hundred and fifty-nine women transported by cattle car from Auschwitz to the merciless conditions of Bergen-Belsen, a barren tract of mud. In a cold, wet autumn, they suffered through nights on flooded straw in overcrowded tents, without light, surrounded by latrine ditches, until a violent hailstorm tore away what had passed for shelter. Weakened by brutality, chaos, and hunger, fifty thousand men and women—insufficiently clothed, tormented by lice—succumbed, many to the typhus epidemic.

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]

The number of Afro-Germans in Germany when the Nazis came to power is variously estimated at 5,000–25,000.[454] It is not clear whether these figures included Asians. Although blacks, including prisoners of war, in Germany and German-occupied Europe were subjected to incarceration, sterilization, murder, and other abuse, there was no programme to kill them all as there was for the Jews.[455]

Browning’s massive but highly readable work (some parts of which were written by the German scholar Jürgen Matthäus) covers every aspect of this question and incorporates all significant previous research. While new interpretations are, of course, likely to be offered in the future, it is most unlikely, barring the discovery of new documents of great importance, that we will ever have a clearer picture of this process than the one Browning offers. This is not to say that the evolution of Nazi policy towards the Jews in this period is now crystal clear”it emphatically is not”but it is to say that all the evidence that an historian can bring to bear on this question has now been synthesized in the clearest form it is ever likely to have.
The first transcription of Anne's diary was in German, made by Otto Frank for his friends and relatives in Switzerland, who convinced him to send it for publication.[23] The second, a composition of Anne Frank's versions A and B as well as excerpts from her essays became the first draft submitted for publication, with an epilogue written by a family friend explaining the fate of its author. In the spring of 1946, it came to the attention of Dr. Jan Romein and his wife Annie Romein-Verschoor, two Dutch historians. They were so moved by it that Anne Romein made unsuccessful attempts to find a publisher, which led Romein to write an article for the newspaper Het Parool:[24]

Gentiles whose status placed them on the periphery of a community generally had fewer social constraints and a higher level of independence. This sense of independence, in turn, seems to have made many rescuers more likely to act in accordance with their personal values and moral precepts, even when these standards were in opposition to societal norms. Such rescuers were propelled by values connected to self-approval. In interviews, they insisted again and again that they had to be at peace with themselves, with their ideas of what was right or wrong.
In June 1941, Mengele was posted to Ukraine, where he was awarded the Iron Cross 2nd Class. In January 1942, he joined the 5th SS Panzer Division Wiking as a battalion medical officer. After rescuing two German soldiers from a burning tank, he was decorated with the Iron Cross 1st Class, the Wound Badge in Black, and the Medal for the Care of the German People. He was declared unfit for further active service in mid-1942, when he was seriously wounded in action near Rostov-on-Don. Following his recovery, he was transferred to the headquarters of the SS Race and Settlement Main Office in Berlin, at which point he resumed his association with von Verschuer, who was now director of the Kaiser Wilhelm Institute of Anthropology, Human Heredity, and Eugenics. Mengele was promoted to the rank of SS-Hauptsturmführer (captain) in April 1943.[20][21][22]
