Estimates of Jewish participation in partisan units throughout Europe range from 20,000 to 100,000.[323] In the occupied Polish and Soviet territories, thousands of Jews fled into the swamps or forests and joined the partisans,[324] although the partisan movements did not always welcome them.[325] An estimated 20,000 to 30,000 joined the Soviet partisan movement.[326] One of the famous Jewish groups was the Bielski partisans in Belarus, led by the Bielski brothers.[324] Jews also joined Polish forces, including the Home Army. According to Timothy Snyder, "more Jews fought in the Warsaw Uprising of August 1944 than in the Warsaw Ghetto Uprising of April 1943".[327][r]

The book of Esther, it has often been remarked, is a quintessentially diasporic text. It takes place entirely outside the Land of Israel and deals with themes that are staples of the diaspora experience: anti-Semitism, Jews passing as Gentiles, the need for a special kind of politics, the issue of Jews who obtain influence in non-Jewish societies, and so forth. The phenomenon of the righteous Gentile is part of this experience, too.

Yet any projection of Anne Frank as a contemporary figure is an unholy speculation: it tampers with history, with reality, with deadly truth. “When I write,” she confided, “I can shake off all my cares. My sorrow disappears, my spirits are revived!” But she could not shake off her capture and annihilation, and there are no diary entries to register and memorialize the snuffing of her spirit. Anne Frank was discovered, seized, and deported; she and her mother and sister and millions of others were extinguished in a program calculated to assure the cruellest and most demonically inventive human degradation. The atrocities she endured were ruthlessly and purposefully devised, from indexing by tattoo through systematic starvation to factory-efficient murder. She was designated to be erased from the living, to leave no grave, no sign, no physical trace of any kind. Her fault—her crime—was having been born a Jew, and as such she was classified among those who had no right to exist: not as a subject people, not as an inferior breed, not even as usable slaves. The military and civilian apparatus of an entire society was organized to obliterate her as a contaminant, in the way of a noxious and repellent insect. Zyklon B, the lethal fumigant poured into the gas chambers, was, pointedly, a roach poison.
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]
Many Jews were saved by hiding and also by illegal frontier crossings. Anne Frank‘s family hid in the concealed annex of an Amsterdam office building with the help of a Christian friend, and the family of Emmanuel Ringelblum (the Warsaw ghetto historian) hid in Warsaw in a specially prepared underground bunker camouflaged by a Polish gardener’s greenhouse. Both the Franks and the Ringelblums were caught and perished. About 20,000 Polish Jews, however, did survive hidden in Aryan Warsaw. Likewise, 5,000 Dutch Jews and several thousand German Jews were hidden in the heart of the Nazi empire, in Berlin and Hamburg.
As Siksnianas led Freund through the woods, he told an astonishing story about a group of prisoners who had reportedly tunneled to freedom and joined partisan fighters hiding out in the forest. But when Freund asked to see exactly how they made it out, he got only shrugs. No one could show him; no one knew. Because a tunnel had never been definitively located and documented, the story had come to take on the contours of a fable, and three-quarters of a century on, it seemed destined to remain a legend without any verifiable evidence to back it up—a crucial piece of the historical record, lost to time.
After invading Poland, the Germans established ghettos in the incorporated territories and General Government to confine Jews.[143] The ghettos were formed and closed off from the outside world at different times and for different reasons.[196][197] For example, the Łódź ghetto was closed in April 1940,[143] to force the Jews inside to give up money and valuables;[198] the Warsaw ghetto was closed for health considerations (for the people outside, not inside, the ghetto),[199] but this did not happen until November 1940;[143] and the Kraków ghetto was not established until March 1941.[200] The Warsaw Ghetto contained 380,000 people[143] and was the largest ghetto in Poland; the Łódź Ghetto was the second largest,[201] holding between 160,000[202] to 223,000.[203] Because of the long drawn-out process of establishing ghettos, it is unlikely that they were originally considered part of a systematic attempt to eliminate Jews completely.[204]

Wounded while on campaign, Mengele returned to Germany in January 1943. He began work at the Kaiser Wilhelm Institute (KWI) for Anthropology, Human Genetics, and Eugenics, directed by his former mentor von Verschuer. In April of 1943, he received a promotion to the rank of SS captain. This promotion shortly preceded Mengele's transfer to Auschwitz, on May 30, 1943.

Josef Mengele was born on March 16, 1911, in Günzburg, near Ulm, Germany. He was the eldest son of Karl Mengele, a prosperous manufacturer of farming implements. In 1935, he earned a PhD in physical anthropology from the University of Munich. He also held a doctoral degree in genetic medicine. In January 1937, he became the assistant of Dr. Otmar von Verschuer at the Institute for Hereditary Biology and Racial Hygiene in Frankfurt. Verschuer was a leading scientific figure widely known for his research with twins.

Some ghettos were initially open, which meant that Jews could leave the area during the daytime but had to be back by a curfew. Later, all ghettos became closed, meaning that Jews were not allowed to leave under any circumstances. Major ghettos were located in the cities of Polish cities of Bialystok, Lodz, and Warsaw. Other ghettos were found in present-day Minsk, Belarus; Riga, Latvia; and Vilna, Lithuania. The largest ghetto was in Warsaw. At its peak in March 1941, some 445,000 were crammed into an area just 1.3 square miles in size.

The first systematic selection for the gas chambers at Birkenau was made when a transport of Jews arrived at Auschwitz on July 4, 1942. The train stopped a short distance from the Auschwitz train station at a wooden platform called the "Judenrampe," where the selection process took place. The Jews who were considered fit to work were marched to the Auschwitz main camp, which was close to the Judenrampe. There they were given a shower, their heads were shaved, a number was tattooed on their left forearm, and a registration card was made for them.
Twins in the experiments describe three days of what must have been psychological examination and three days of laboratory experiments. "Three times a week we were marched to Auschwitz to a big brick building, sort of like a big gymnasium. They would keep us there for about six or eight hours at a time - most of the days. ..... We would have to sit naked in the large room where we first entered, and people in white jackets would observe us and write down notes. They also would study every part of our bodies. They would photograph, measure our heads and arms and bodies, and compare the measurements of one twin to another. The process seemed to go on and on." (Echoes from Auschwitz, Kor).
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]
The St. Louis arrived in Havana harbor on May 27th. Of the 937 passengers on board, only 28 passengers were allowed into Cuba. 22 of these passengers were Jewish and had valid U.S. visas, 4 were Spanish citizens and 2 were Cuban nationals, all with valid documents. This story gained a lot of publicity; it was spread throughout Europe and the United States. The U.S. newspapers reported the story compassionately, but only a handful suggested that the refugees should come to the United States. The United States government decided not to take the steps to permit the passengers into the country.
Jewish deportees in the Drancy transit camp near Paris, France, in 1942, on their last stop before the German concentration camps. Some 13,152 Jews (including 4,115 children) were rounded up by French police forces, taken from their homes to the "Vel d'Hiv", or winter cycling stadium in southwestern Paris, in July of 1942. They were later taken to a rail terminal at Drancy, northeast of the French capital, and then deported to the east. Only a handful ever returned. #
Many Jews attempted to flee Germany, and thousands succeeded by immigrating to such countries as Belgium, Czechoslovakia, England, France and Holland. It was much more difficult to get out of Europe. Jews encountered stiff immigration quotas in most of the world's countries. Even if they obtained the necessary documents, they often had to wait months or years before leaving. Many families out of desperation sent their children first.
The Germans began World War II by invading Poland in September 1939. The Nazi leaders then shifted priorities in anti-Jewish policy from expulsion from German-controlled territory to concentration of European Jewish populations in locations suited to future permanent removal. It is not clear that the Nazi leaders were already envisioning mass murder as their "solution" to their so-called Jewish problem.

To those whose knowledge of the Holocaust consists, essentially, of the fact that Hitler killed the Jews, it often comes as a surprise to learn that, in the first seven and a half years of Nazi rule in Germany, he did no such killing: Jews were not deliberately murdered by the Nazi regime until the invasion of the Soviet Union in June 1941. In Karl Schleunes’ famous phrase, there was a “twisted road to Auschwitz,” with a gradual but by no means direct path to continental genocide. For the first few years of Nazi rule in Germany”Hitler came to power in January 1933 as chancellor and consolidated his rule after the death of President von Hindenburg a year later”Nazi policy aimed “merely” at the removal of Jews from positions of authority, especially in the state sector, with such removal constantly reinforced by the totalitarian regime’s propaganda and its police terrorism. 

Most of the Jewish ghettos of General Government were liquidated in 1942–1943, and their populations shipped to the camps for extermination.[349][350][t] About 42,000 Jews were shot during the Operation Harvest Festival on 3–4 November 1943.[351] At the same time, rail shipments arrived regularly from western and southern Europe at the extermination camps.[352] Few Jews were shipped from the occupied Soviet territories to the camps: the killing of Jews in this zone was mostly left in the hands of the SS, aided by locally recruited auxiliaries.[353][u]
Any remaining notes Mengele carried with him on his escape to South America and those were never found. Some forty years after the war, only a few of these twins could be found, many living in Israel and the United States. Strangely enough, many of them recall Mengele as a gentle, affable man who befriended them as children and gave them chocolates. Since many had immediately been separated from their families upon entering the camp, Mengele became a sort of father figure. Still a tension existed, that at any time they could be killed if they did not keep a low profile. Older twins recognized his kindness as a deception ...
Executions by the Einsatzgruppen, mobile killing squads,were abandoned for practical reasons. Although approximately 1.5 million Jews had been shot by the winter of 1941, the Nazis felt that the efficiency of this slow and cumbersome method left much to be desired. Moreover, they found it was bad for the sol­diers’ morale. Himmler himself, commander of the SS and as such responsible for the annihilation of the Jews, was persuaded, after having witnessed such an execu­tion, that it badly affected the mental health of those carrying out the execution. The institutionalization of organized murder, founded on a division of labor and carried out in special installations expressly designed for this purpose, distanced the executioner from the victim, an indispensable psychological advantage in an enterprise of annihilation of such a huge scale.
What could be more "useful" than to view that era through the mind and eyes -- and in the words -- of a girl who wanted us to know who she was and what happened to her. And what could be more necessary than the story of a girl who wanted to grow up, to become a writer, to lead a full and normal life -- and was prevented from doing so, by the forces of prejudice and hatred, on a beautiful and otherwise ordinary August morning.
Tens of thousands of Jews held in the eastern territories were marched towards the heart of Germany so they could not bear witness to the Allies. Aware that the world had been alerted to the horrors of the camps, the Nazis sought to destroy evidence. In June, Soviet forces liberated the first major camp, known as Majdanek, in Lublin, Poland. The Nazis had burned down the crematorium chimney but had failed to destroy the gas chambers and barracks. Only a few hundred inmates were still alive.
Advocacy organizations worldwide called for British Royal Air Forces to bomb concentration camps particularly at Auschwitz. Although the plan was adopted by British Prime Minister Winston Churchill poor information-sharing between parts of the British government led the order to be ignored and the plan dropped. Such calculations were hardly the low point of Allied Responses. One story has that, low on supplies, the Nazis offered the British a million Jews in exchange for 10,000 trucks, which one British diplomat promptly refused saying, “What would I do with one million Jews? Where would I put them?”
^ Goebbels noted: "Regarding the Jewish question, the Fuhrer is determined to clear the table. He warned the Jews that if they were to cause another world war, it would lead to their own destruction. Those were not empty words. Now the world war has come. The destruction of the Jews must be its necessary consequence. We cannot be sentimental about it. It is not for us to feel sympathy for the Jews. We should have sympathy rather with our own German people. If the German people have to sacrifice 160,000 victims in yet another campaign in the east, then those responsible for this bloody conflict will have to pay for it with their lives."[262]

As Nazi tyranny spread across Europe, the Germans and their collaborators persecuted and murdered millions of other people. Between two and three million Soviet prisoners of war were murdered or died of starvation, disease, neglect, or brutal treatment. The Germans targeted the non-Jewish Polish intelligentsia for killing, and deported millions of Polish and Soviet civilians for forced labor in Germany or in occupied Poland, where these individuals worked and often died under deplorable conditions.
Britain's attitude to Jewish refugees from Nazi-controlled areas was strongly influenced by its role as the mandatory power in Palestine, where it had to mediate between Jewish and Arab interests. In December 1941, the Struma, a ship carrying 769 Jewish refugees, left the Romanian port of Constantsa hoping to reach Palestine. Towed into Istanbul harbour when its engines failed, it became the subject of diplomatic discussions between Britain and Turkey. Britain's chief concern was to discourage what it regarded as an undesirable traffic, and it proposed that the ship be returned to Romania. After ten weeks of wrangling the Struma was towed out to sea, its engines still disabled, where it was sunk by a Soviet submarine. There was one survivor.
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]
Romania implemented anti-Jewish measures in May and June 1940 as part of its efforts towards an alliance with Germany. Jews were forced from government service, pogroms were carried out, and by March 1941 all Jews had lost their jobs and had their property confiscated.[169] After Romania joined the invasion of the Soviet Union in June 1941, at least 13,266 Jews were killed in the Iași pogrom,[170] and Romanian troops carried out massacres in Romanian-controlled territory, including the Odessa massacre of 20,000 Jews in Odessa in late 1941. Romania also set up concentration camps under its control in Transnistria, where 154,000–170,000 Jews were deported from 1941 to 1943.[169]
The Nazi invasion of the Soviet Union codenamed Operation Barbarossa, which commenced on 22 June 1941, set in motion a "war of destruction" which quickly opened the door to systematic mass murder of European Jews.[30] For Hitler, Bolshevism was merely "the most recent and most nefarious manifestation of the eternal Jewish threat".[31] On 3 March 1941, Wehrmacht Joint Operations Staff Chief Alfred Jodl repeated Hitler's declaration that the "Jewish-Bolshevik intelligentsia would have to be eliminated" and that the forthcoming war would be a confrontation between two completely opposing cultures.[32] In May 1941, Gestapo leader Heinrich Müller wrote a preamble to the new law limiting the jurisdiction of military courts in prosecuting troops for criminal actions because: "This time, the troops will encounter an especially dangerous element from the civilian population, and therefore, have the right and obligation to secure themselves."[33]

Höss oversaw the rapid construction of a gigantic new annex called Birkenau containing four large gas chamber-crematory buildings and scores of huts for slave laborers. From the moment it became operational in the spring of 1943, Auschwitz-Birkenau served as the focal point of the Nazi effort to exterminate the Jews. Hour after hour, trainloads of Jews arrived from all over Europe. The people were subjected to a life-and-death selection process by SS medical personnel such as Dr. Josef Mengele. Adults who seemed fit for labor were allowed to live and were marched away. All others, including children, the elderly and anyone deemed unfit went straight to the gas chambers.
Most Holocaust historians define the Holocaust as the enactment, between 1941 and 1945, of the German state policy to exterminate the European Jews.[a] In Teaching the Holocaust (2015), Michael Gray, a specialist in Holocaust education,[27] offers three definitions: (a) "the persecution and murder of Jews by the Nazis and their collaborators between 1933 and 1945", which views the events of Kristallnacht in Germany in 1938 as an early phase of the Holocaust; (b) "the systematic mass murder of the Jews by the Nazi regime and its collaborators between 1941 and 1945", which acknowledges the shift in German policy in 1941 toward the extermination of the Jewish people in Europe; and (c) "the persecution and murder of various groups by the Nazi regime and its collaborators between 1933 and 1945", which includes all the Nazis' victims. The third definition fails, Gray writes, to acknowledge that only the Jewish people were singled out for annihilation.[28]
The German skill in adapting the 20th century techniques of mass production was applied in engineering the “Final Solution.” In 1941, the engineers of the “Final Solution” utilized these same principles to cheaply and efficiently murder millions of Jews and other “undesirables.” The plants established to carry out this mass murder were the death camps.
On the eve of World War II, the Führer (supreme leader) publicly threatened the Jews of Europe during a speech in Berlin: "In the course of my life I have very often been a prophet, and have usually been ridiculed for it. During the time of my struggle for power it was in the first instance only the Jewish race that received my prophecies with laughter when I said that I would one day take over the leadership of the State, and with it that of the whole nation, and that I would then among other things settle the Jewish problem. Their laughter was uproarious, but I think that for some time now they have been laughing on the other side of their face. Today I will once more be a prophet: if the international Jewish financiers in and outside Europe should succeed in plunging the nations once more into a world war, then the result will not be the Bolshevizing of the earth, and thus the victory of Jewry, but the annihilation of the Jewish race in Europe!"
The photo above was taken while Mengele was home on leave, after spending 5 months at Auschwitz-Birkenau. He is wearing an Iron Cross medal on the pocket of his uniform. Mengele was very proud of his medals; he earned the Iron Cross 2nd Class shortly after he was sent to the Ukraine in June 1941 at the time of the German invasion of the Soviet Union. In January 1942, Mengele joined the prestigious 5th SS Panzer Division, nicknamed the Viking Division. In July 1942, he was awarded the Iron Cross 1st Class after he pulled two wounded soldiers out of a burning tank under enemy fire on the battlefield, and administered medical first aid to them.
He sent one entire Jewish block of 600 women to the gas chamber and cleared the block. He then had it disinfected from top to bottom. Then he put bath tubs between this block and the next, and the women from the next block came out to be disinfected and then transferred to the clean block. Here they were given a clean new nightshirt. The next block was cleaned in this way and so on until all the blocks were disinfected. End of typhus! The awful thing was that he could not put those first 600 somewhere.
A week later, he and other members of the crew received a visit from the camp’s Sturmbannführer, or commander, a 30-year-old dandy who wore boots polished shiny as mirrors, white gloves that reached up to his elbows, and smelled strongly of perfume. Zeidel remembered what the commandant told them: “Just about 90,000 people were killed here, lying in mass graves.” But, the Sturmbannführer explained, “there must not be any trace” of what had happened at Ponar, lest Nazi command be linked to the mass murder of civilians. All the bodies would have to be exhumed and burned. The wood collected by Zeidel and his fellow prisoners would form the pyres.
Responding with alarm to Hitler’s rise, the Jewish community sought to defend their rights as Germans. For those Jews who felt themselves fully German and who had patriotically fought in World War I, the Nazification of German society was especially painful. Zionist activity intensified. “Wear it with pride,” journalist Robert Weltsch wrote in 1933 of the Jewish identity the Nazis had so stigmatized. Religious philosopher Martin Buber led an effort at Jewish adult education, preparing the community for the long journey ahead. Rabbi Leo Baeck circulated a prayer for Yom Kippur (the Day of Atonement) in 1935 that instructed Jews on how to behave: “We bow down before God; we stand erect before man.” Yet while few, if any, could foresee its eventual outcome, the Jewish condition was increasingly perilous and was expected to worsen.

When exactly Hitler settled on straightforward murder as a means of removal has been harder to pinpoint. As Yale historian Timothy Snyder writes, “It cannot be stressed enough that the Nazis did not know how to eradicate the Jews when they began the war against the Soviet Union [in the summer of 1941]… They could not be confident that SS men would shoot women and children in large numbers.” But as Operation Barbarossa, the name for the Nazi invasion of the U.S.S.R, proved during the mass shootings of June 1941 and the massacres at Kiev in September, the Order Police and Einsatzgrüppen were more than willing to commit mass murders. This meant Hitler could take the solution to the Jewish problem to its “furthest extremes,” in the words of Philipp Bouhler, the senior Nazi official responsible for the euthanasia program that killed more than 70,000 handicapped German people.
By the spring of 1945, German leadership was dissolving amid internal dissent, with Goering and Himmler both seeking to distance themselves from Hitler and take power. In his last will and political testament, dictated in a German bunker that April 29, Hitler blamed the war on “International Jewry and its helpers” and urged the German leaders and people to follow “the strict observance of the racial laws and with merciless resistance against the universal poisoners of all peoples”–the Jews. The following day, he committed suicide. Germany’s formal surrender in World War II came barely a week later, on May 8, 1945.

The Holocaust, also known as the Shoah,[b] was a genocide during World War II in which Nazi Germany, aided by local collaborators, systematically murdered some six million European Jews—around two-thirds of the Jewish population of Europe—between 1941 and 1945.[a][c] Jews were targeted for extermination as part of a larger event during the Holocaust era, in which Germany and its collaborators persecuted and murdered other groups, including Slavs (chiefly ethnic Poles, Soviet prisoners of war, and Soviet citizens), the Roma, the "incurably sick", political and religious dissenters such as communists and Jehovah's Witnesses, and gay men.[d] Taking into account all the victims of Nazi persecution, the death toll rises to over 17 million.[3]

Holocaust, Hebrew Shoʾah (“Catastrophe”), Yiddish and Hebrew Ḥurban (“Destruction”), the systematic state-sponsored killing of six million Jewish men, women, and children and millions of others by Nazi Germany and its collaborators during World War II. The Germans called this “the final solution to the Jewish question.” Yiddish-speaking Jews and survivors in the years immediately following their liberation called the murder of the Jews the Ḥurban, the word used to describe the destruction of the First Temple in Jerusalem by the Babylonians in 586 bce and the destruction of the Second Temple by the Romans in 70 ce. Shoʾah (“Catastrophe”) is the term preferred by Israelis and the French, most especially after Claude Lanzmann’s masterful 1985 motion picture documentary of that title. It is also preferred by people who speak Hebrew and by those who want to be more particular about the Jewish experience or who are uncomfortable with the religious connotations of the word Holocaust. Less universal and more particular, Shoʾah emphasizes the annihilation of the Jews, not the totality of Nazi victims. More particular terms also were used by Raul Hilberg, who called his pioneering work The Destruction of the European Jews, and Lucy S. Dawidowicz, who entitled her book on the Holocaust The War Against the Jews. In part she showed how Germany fought two wars simultaneously: World War II and the racial war against the Jews. The Allies fought only the World War. The word Holocaust is derived from the Greek holokauston, a translation of the Hebrew word ʿolah, meaning a burnt sacrifice offered whole to God. This word was chosen because in the ultimate manifestation of the Nazi killing program—the extermination camps—the bodies of the victims were consumed whole in crematoria and open fires.
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:
Uprisings broke out in some extermination camps. The few remaining Jews kept alive to dispose of bodies and sort possessions realised the number of transportees was reducing and they would be next. Civilian uprisings occurred across Poland as mainly young Jews, whose families had already been murdered, began to resist Nazi oppression. With reports of rebellion and mass murder in the British press, the situation in the camps could no longer be be ignored.
Many healthy, young strong Jews were not killed immediately. The Germans' war effort and the “Final Solution” required a great deal of manpower, so the Germans reserved large pools of Jews for slave labor. These people, imprisoned in concentration and labor camps, were forced to work in German munitions and other factories, such as I.G. Farben and Krupps, and wherever the Nazis needed laborers. They were worked from dawn until dark without adequate food and shelter. Thousands perished, literally worked to death by the Germans and their collaborators.

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.

Overnight on November 9-10, 1938, the Nazis incited a pogrom against Jews in Austria and Germany called Kristallnacht (Night of Broken Glass, or literally translated from German, "Crystal Night"). This included the pillaging and burning of synagogues, the breaking of windows of Jewish-owned businesses and the looting of those stores. In the morning, broken glass littered the ground. Many Jews were physically attacked or harassed, and approximately 30,000 were arrested and sent to concentration camps.

Pogroms occurred in several countries occupied by, or supportive of, Germany, attacks that were both encouraged by the Germans and carried out without their involvement.[225] Thousands of Jews were killed in January and June 1941 in the Bucharest pogrom and Iaşi pogrom in Romania, a German ally.[226] According to a 2004 report written by Tuvia Friling and others, up to 14,850 Jews died during the Iaşi pogrom.[227] The Romanian military killed up to 25,000 Jews in Odessa, then under Romanian control, between 18 October 1941 and March 1942, assisted by gendarmes and the police.[228] Mihai Antonescu, Romania's deputy prime minister, is reported as saying it was "the most favorable moment in our history" to solve the "Jewish problem".[229] In July 1941 he said it was time for "total ethnic purification, for a revision of national life, and for purging our race of all those elements which are foreign to its soul, which have grown like mistletoes and darken our future".[230]

In the autumn of 1941, SS chief Heinrich Himmler assigned German General Odilo Globocnik (SS and police leader for the Lublin District) with the implementation of a plan to systematically murder the Jews of the Generalgouvernement. The code name Operation Reinhard was eventually given to this plan, named after Heydrich (who was assassinated by Czech partisans in May 1942). As part of Operation Reinhard, Nazi leaders established three killing centers in Poland—Belzec, Sobibor, and Treblinka—with the sole purpose of the mass murder of Jews.
Half a year later, Harel was replaced by Meir Amit, who ordered the Mossad to “stop chasing after ghosts from the past and devote all our manpower and resources to threats against the security of the state.” He mandated that the agency deal with Nazis “only to the extent it is able to do so, in addition to its principal missions” and as long as “it doesn’t impinge on the other operations.”
Mengele managed to escape imprisonment after the war, first by working as a farm stableman in Bavaria, then by moving to South America. He became a citizen of Paraguay in 1959. He later moved to Brazil, where he met up with another former Nazi party member, Wolfgang Gerhard. In 1985, a multinational team of forensic experts traveled to Brazil in search of Mengele. They determined that a man named Gerhard had died of a stroke while swimming in 1979. Dental records later revealed that Mengele had, at some point, assumed Gerhard’s identity and was the stroke victim.
At each of the death camps, special squads of Jewish slave laborers called Sonderkommandos were utilized to untangle the victims and remove them from the gas chamber. Next they extracted any gold fillings from teeth and searched body orifices for hidden valuables. The corpses were disposed of by various methods including mass burials, cremation in open fire pits or in specially designed crematory ovens such as those used at Auschwitz. All clothing, money, gold, jewelry, watches, eyeglasses and other valuables were sorted out then shipped back to Germany for re-use. Women's hair was sent to a firm in Bavaria for the manufacture of felt.
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:
The economic strains of the Great Depression led some in the German medical establishment to advocate murder (euphemistically called "euthanasia") of the "incurable" mentally and physically disabled as a cost-saving measure to free up funds for the curable.[66] By the time the National Socialist German Workers' Party, or Nazi Party,[j] came to power in 1933, there was already a tendency to seek to save the racially "valuable", while ridding society of the racially "undesirable".[68] The party had originated in 1920[67] as an offshoot of the völkisch movement, and it adopted that movement's antisemitism.[69] Early antisemites in the party included Dietrich Eckart, publisher of the Völkischer Beobachter, the party's newspaper, and Alfred Rosenberg, who wrote antisemitic articles for it in the 1920s. Rosenberg's vision of a secretive Jewish conspiracy ruling the world would influence Hitler's views of Jews by making them the driving force behind communism.[70] The origin and first expression of Hitler's antisemitism remain a matter of debate.[71] Central to his world view was the idea of expansion and lebensraum (living space) for Germany. Open about his hatred of Jews, he subscribed to the common antisemitic stereotypes.[72] From the early 1920s onwards, he compared the Jews to germs and said they should be dealt with in the same way. He viewed Marxism as a Jewish doctrine, said he was fighting against "Jewish Marxism", and believed that Jews had created communism as part of a conspiracy to destroy Germany.[73]
This past fall, I reached out to Hana Amir, Zeidel’s daughter, and we spoke several times over Skype. From her home in Tel Aviv, Amir, who is slight and spectacled, with a gray bob, told me about how she learned of her father’s story. When Amir was young, Zeidel worked as a truck driver, and he was gone for long stretches at a time. At home, he was withholding with his daughter and two sons. “My father was of a generation that didn’t talk about their emotions, didn’t talk about how they felt about what they’d been through,” Amir told me. “This was their coping mechanism: If you’re so busy with moving forward, you can disconnect from your memories.” But there were signs that the past wasn’t done with Zeidel: Amir believes he suffered from recurrent nightmares, and he was fastidious about his personal hygiene—he washed his hands many times a day.
In early 1943, encouraged by von Verschuer, Mengele applied to transfer to the concentration camp service.[20][30] His application was accepted and he was posted to Auschwitz, where he was appointed by SS-Standortarzt Eduard Wirths, chief medical officer at Auschwitz, to the position of chief physician of the Zigeunerfamilienlager (Romani family camp) at Birkenau,[20][30] a subcamp located on the main Auschwitz complex. The SS doctors did not administer treatment to the Auschwitz inmates, but supervised the activities of inmate doctors who had been forced to work in the camp medical service.[31] As part of his duties, Mengele made weekly visits to the hospital barracks and ordered any prisoners who had not recovered after two weeks in bed to be sent to the gas chambers.[32]
