As if cold-blooded murder of millions of Jews was not enough, it was done with extreme, perverse cruelty. The victims were packed into cattle trains with standing-room only and without food or water, or heat in the winter, or toilet facilities. Many did not arrive at the camps alive. Those who did arrive at their destination had their heads shaved, with the hair to be used for stuffing mattresses. Stripped of all clothing, most were herded naked into the gas chambers. Dr Johann Kremer, a German SS surgeon, described the gassing of a group of French Jews including 150 boys and girls under the age of 15:
The book Children of the Flames by Joe E. White chronicles the notorious medical experimental activities of Josef Mengele on approximately three thousand twins who passed through the Auschwitz death camp during WWII until its liberation at the end of the war. Only a few of the three thousand twins survived and now fifty years later they have told their story of how they were given special privileges in Auschwitz due to Mengele’s interest in twins and how as a result they have suffered during the past fifty years as the children who survived the still unknown and unexplained medical experiments and injections which they were subjected to at the hands of Josef Mengele.
Zeidel had spent the previous two years in German-occupied Vilnius, in the city’s walled-off Jewish ghetto. He’d watched as the Nazis sent first hundreds and then thousands of Jews by train or truck or on foot to a camp in the forest. A small number of people managed to flee the camp, and they returned with tales of what they’d seen: rows of men and women machine-gunned down at close range. Mothers pleading for the lives of their children. Deep earthen pits piled high with corpses. And a name: Ponar.
Paradoxically, at the same time that Germany tried to rid itself of its Jews via forced emigration, its territorial expansions kept bringing more Jews under its control. Germany annexed Austria in March 1938 and the Sudetenland (now in the Czech Republic) in September 1938. It established control over the Protectorate of Bohemia and Moravia (now in the Czech Republic) in March 1939. When Germany invaded Poland on September 1, 1939, the “Jewish question” became urgent. When the division of Poland between Germany and the Soviet Union was complete, more than two million more Jews had come under German control. For a time, the Nazis considered shipping the Jews to the island of Madagascar, off the southeast coast of Africa, but discarded the plan as impractical; the Nazis had not prevailed in the Battle of Britain, the seas had become a war zone, and the resources required for such a massive deportation were scarce.
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.
As the tide of World War II turned against the Nazis, they began a systematic plan to eliminate or "liquidate" the ghettos they had established, by a combination of mass murder on the spot and transferring the remaining residents to extermination camps. When the Nazis attempted to liquidate the Warsaw Ghetto on April 13, 1943, the remaining Jews fought back in what has become known as the Warsaw Ghetto Uprising. The Jewish resistance fighters held out against the entire Nazi regime for 28 days, longer than many European countries had been able to withstand Nazi conquest.
Amir told me that Zeidel made several pilgrimages back to Ponar. And yet he was never able to locate the passageway that carried him to freedom. What Zeidel didn’t know was that three years before he died, a Lithuanian archaeologist named Vytautas Urbanavicius had quietly excavated what turned out to be the tunnel’s entrance. But after taking a few photographs and a notebook’s worth of measurements, he sealed up the hole with fresh mortar and stone without pressing any farther or prominently marking the area.
Throughout German-occupied territory the situation of the Jews was desperate. They had meagre resources and few allies and faced impossible choices. A few people came to their rescue, often at the risk of their own lives. Swedish diplomat Raoul Wallenberg arrived in Budapest on July 9, 1944, in an effort to save Hungary’s sole remaining Jewish community. Over the next six months, he worked with other neutral diplomats, the Vatican, and Jews themselves to prevent the deportation of these last Jews. Elsewhere, Le Chambon-sur-Lignon, a French Huguenot village, became a haven for 5,000 Jews. In German-occupied Poland, where it was illegal to aid Jews and where such action was punishable by death, the Zegota (Council for Aid to Jews) rescued a similar number of Jewish men, women, and children. Financed by the London-based Polish government in exile and involving a wide range of clandestine political organizations, Zegota provided hiding places and financial support and forged identity documents.
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).
Mengele firmly endorsed Nazi racial theory and engaged in a wide spectrum of experiments which aimed to illustrate the lack of resistance among Jews or Roma to various diseases. He also attempted to demonstrate the “degeneration” of Jewish and “Gypsy” blood through the documentation of physical oddities and the collection and harvesting of tissue samples and body parts. Many of his “test subjects” died as a result of the experimentation or were murdered in order to facilitate post-mortem examination.
Anne Frank's extraordinary diary, written in the Amsterdam attic where she and her family hid from the Nazis for two years, has become a world classic and a timeless testament to the human spirit. Now, in a new edition enriched by many passages originally withheld by her father, we meet an Anne more real, more human, and more vital than ever. Here she is first and foremost ...more

Killing on a mass scale using gas chambers or gas vans was the main difference between the extermination and concentration camps.[269] From the end of 1941, the Germans built six extermination camps in occupied Poland: Auschwitz II-Birkenau, Majdanek, Chełmno, and the three Operation Reinhard camps at Belzec, Sobibor, and Treblinka II.[44][270] Maly Trostenets, a concentration camp in the Reichskommissariat Ostland, became a killing centre in 1942.[44] Gerlach writes that over three million Jews were murdered in 1942, the year that "marked the peak" of the mass murder of Jews.[271] At least 1.4 million of these were in the General Government area of Poland.[272]

“In any of these circumstances, what you want—the biggest thing you want, the most important—is to be able to make these places visible,” Freund told me later, back in Vilnius. “Your goal is to mark them in a way that people can come to them with tears in their eyes, come to them as memorials, come to them to say the mourner’s kaddish. Because the worst thing would be to look away. To forget.”
The ideology of Nazism brought together elements of antisemitism, racial hygiene, and eugenics, and combined them with pan-Germanism and territorial expansionism with the goal of obtaining more Lebensraum (living space) for the Germanic people.[16] Nazi Germany attempted to obtain this new territory by attacking Poland and the Soviet Union, intending to deport or kill the Jews and Slavs living there, who were considered by the Nazis to be inferior to the Aryan master race.[17]
