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]
We were faced with the question: what about the women and children? – I have decided on a solution to this problem. I did not consider myself justified to exterminate the men only – in other words, to kill them or have them killed while allowing the avengers, in the form of their children, to grow up in the midst of our sons and grandsons. The difficult decision had to be made to have this people disappear from the earth.
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]

In October 1941 the Nazis began turning the concentration camp at Majdanek into a death camp as well. They then began the construction of killing centres at Bełżec, Treblinka, near Warsaw, and at Sobibór. The first mass gassing of Jews began in Chelmno on 8 December 1941, when the Nazis used gas vans to murder people from the Łódź ghetto. The Nazis also ordered the expansion of the Auschwitz camp complex to increase the capacity for murder.

On November 4, 1943, Globocnik wrote to Himmler from Trieste: "I have, on Oct. 19, 1943, completed Action Reinhard, and closed all the camps." He asked for special medals for his men in recognition of their "specially difficult task".

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.
An SS report described the scene: "The Jews stayed in the burning buildings until because of the fear of being burned alive they jumped down from the upper stories…With their bones broken, they still tried to crawl across the street into buildings which had not yet been set on fire…Despite the danger of being burned alive the Jews and bandits often preferred to return into the flames rather than risk being caught by us."

By mid-1944 those Jewish communities within easy reach of the Nazi regime had been largely exterminated,[367] in proportions ranging from about 25 percent in France[368] to more than 90 percent in Poland.[369] On 5 May Himmler claimed in a speech that "the Jewish question has in general been solved in Germany and in the countries occupied by Germany".[370] As the Soviet armed forces advanced, the camps in eastern Poland were closed down, with surviving inmates shipped to camps closer to Germany.[371] Efforts were made to conceal evidence of what had happened. The gas chambers were dismantled, the crematoria dynamited, and the mass graves dug up and the corpses cremated.[372] Local commanders continued to kill Jews, and to shuttle them from camp to camp by forced "death marches".[373] Already sick after months or years of violence and starvation, some were marched to train stations and transported for days at a time without food or shelter in open freight cars, then forced to march again at the other end to the new camp. Others were marched the entire distance to the new camp. Those who lagged behind or fell were shot. Around 250,000 Jews died during these marches.[374]

But the diary in itself, richly crammed though it is with incident and passion, cannot count as Anne Frank’s story. A story may not be said to be a story if the end is missing. And because the end is missing, the story of Anne Frank in the fifty years since “The Diary of a Young Girl” was first published has been bowdlerized, distorted, transmuted, traduced, reduced; it has been infantilized, Americanized, homogenized, sentimentalized; falsified, kitschified, and, in fact, blatantly and arrogantly denied. Among the falsifiers have been dramatists and directors, translators and litigators, Anne Frank’s own father, and even—or especially—the public, both readers and theatregoers, all over the world. A deeply truth-telling work has been turned into an instrument of partial truth, surrogate truth, or anti-truth. The pure has been made impure—sometimes in the name of the reverse. Almost every hand that has approached the diary with the well-meaning intention of publicizing it has contributed to the subversion of history.

Twins were subjected to weekly examinations and measurements of their physical attributes by Mengele or one of his assistants.[49] The experiments he performed on twins included unnecessary amputation of limbs, intentionally infecting one twin with typhus or some other disease, and transfusing the blood of one twin into the other. Many of the victims died while undergoing these procedures,[50] and those who survived the experiments were sometimes killed and their bodies dissected once Mengele had no further use for them.[51] Nyiszli recalled one occasion on which Mengele personally killed fourteen twins in one night by injecting their hearts with chloroform.[31] If one twin died from disease, he would kill the other twin to allow comparative post-mortem reports to be produced for research purposes.[52]
SS-Obergruppenführer Reinhard Heydrich, head of the Reich Main Security Office (Reichssicherheitshauptamt or RSHA), convened what became known as the Wannsee Conference on 20 January 1942 at Am Großen Wannsee 56–58, a villa in Berlin's Wannsee suburb.[256][257] The meeting had been scheduled for 9 December 1941, and invitations had been sent on 29 November, but it had been postponed.[258]
The outbreak of war and the invasion of Poland brought a population of 3.5 million Polish Jews under the control of the Nazi and Soviet security forces,[14] and marked the start of a far more savage persecution, including mass killings.[6] In the German-occupied zone of Poland, Jews were forced into hundreds of makeshift ghettos, pending other arrangements.[15] Two years later, with the launch of Operation Barbarossa against the USSR in late June 1941, the German top echelon began to pursue Hitler's new anti-Semitic plan to eradicate, rather than expel, Jews.[16] Hitler's earlier ideas about forcible removal of Jews from the German-controlled territories in order to achieve Lebensraum were abandoned after the failure of the air campaign against Britain, initiating a naval blockade of Germany.[7] Reichsführer-SS Heinrich Himmler became the chief architect of a new plan, which came to be called The Final Solution to the Jewish Question.[17] On 31 July 1941, Reichsmarschall Hermann Göring wrote to Reinhard Heydrich (Himmler's deputy and chief of the RSHA),[18][19] instructing Heydrich to submit concrete proposals for the implementation of the new projected goal.[20]
In the Lviv pogroms in occupied Poland in July 1941, some 6,000 Polish Jews were murdered in the streets, on top of 3,000 arrests and mass shootings by Einsatzgruppe C.[231][m] During the Jedwabne pogrom, on 10 July 1941, a group of 40 Polish men killed several hundred Jews; around 300 were burned alive in a barn. The attack is thought to have been organized by the German Security Police (Sicherheitsdienst).[233] A long debate about who was responsible for the Jedwabne murders was triggered in 2001 by the publication of Jan T. Gross's book Neighbors: The Destruction of the Jewish Community in Jedwabne, Poland.[234] The response to the book was described as "the most prolonged and far-reaching of any discussion of the Jewish issue in Poland since the Second World War".[235]

For Kanin, this kind of rumination was “an embarrassing piece of special pleading. . . . The fact that in this play the symbols of persecution and oppression are Jews is incidental, and Anne, in stating the argument so, reduces her magnificent stature.” And so it went throughout. The particularized plight of Jews in hiding was vaporized into what Kanin called “the infinite.” Reality—the diary’s central condition—was “incidental.” The passionately contemplative child, brooding on concrete evil, was made into an emblem of evasion. Her history had a habitation and a name; the infinite was nameless and nowhere.
According to the Yad Vashem Holocaust Martyrs' and Heroes' Remembrance Authority in Jerusalem, "[a]ll the serious research" confirms that between five and six million Jews died.[391] Early postwar calculations were 4.2 to 4.5 million from Gerald Reitlinger;[392] 5.1 million from Raul Hilberg; and 5.95 million from Jacob Lestschinsky.[393] In 1986 Lucy S. Dawidowicz used the pre-war census figures to estimate 5.934 million.[394] Yehuda Bauer and Robert Rozett in the Encyclopedia of the Holocaust (1990) estimated 5.59–5.86 million.[395] A 1996 study led by Wolfgang Benz suggested 5.29 to 6.2 million, based on comparing pre- and post-war census records and surviving German documentation on deportations and killings.[391] Martin Gilbert arrived at a minimum of 5.75 million.[396] The figures include over one million children.[397]
The first killing center set up in occupied Polish lands was the camp at Chełmno on the Ner; Jews brought in from the ghettos in the Wartheland were being killed there from December 1941. Three more camps, somewhat larger, were opened at Bełżec, Sobibor, and Treblinka (in what was known as “Aktion Reinhard”) somewhat later, between March and July 1942.

Our many Jewish friends and acquaintances are being taken away in droves. The Gestapo is treating them very roughly and transporting them in cattle cars to Westerbork. . . .The people get almost nothing to eat, much less to drink, as water is available only one hour a day, and there’s only one toilet and sink for several thousand people. Men and women sleep in the same room, and women and children often have their heads shaved. . . . If it’s that bad in Holland, what must it be like in those faraway and uncivilized places where the Germans are sending them? We assume that most of them are being murdered. The English radio says they’re being gassed.
On 6 January 1942, the Soviet Minister of Foreign Affairs, Vyacheslav Molotov, sent out diplomatic notes about German atrocities. The notes were based on reports about bodies surfacing from poorly covered graves in pits and quarries, as well as mass graves found in areas the Red Army had liberated, and on witness reports from German-occupied areas.[335] The following month, Szlama Ber Winer escaped from the Chełmno concentration camp in Poland, and passed detailed information about it to the Oneg Shabbat group in the Warsaw Ghetto. His report, known by his pseudonym as the Grojanowski Report, had reached London by June 1942.[288][336] Also in 1942, Jan Karski sent information to the Allies after being smuggled into the Warsaw Ghetto twice.[337][s] On 27 April 1942, Vyacheslav Molotov sent out another note about atrocities.[335] In late July or early August 1942, Polish leaders learned about the mass killings taking place inside Auschwitz. The Polish Interior Ministry prepared a report, Sprawozdanie 6/42,[340] which said at the end:
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]
“One of the things that I always say is you leave room for the next generation of technology to do things that you can’t fathom,” Freund said. “Look, I’m doing things that my teachers never thought of. I don’t have the chutzpah to think that I know all the answers, and maybe in another generation the technology will improve, people will have better ideas, you know?”

A young man sits on an overturned stool next to a burnt body in the Thekla camp outside Leipzig, in April of 1945, after the US troops entered Leipzig April 18. On the 18th of April, the workers of the Thekla plane factory were locked in an isolated building of the factory by the Germans and burned alive by incendiary bombs. About 300 prisoners died. Those who managed to escape died on the barbed wire or were executed by the Hitler youth movement, according to a US captain's report. #
In response to a typhus epidemic in the women's camp, Mengele cleared one block of six hundred Jewish women and sent them to their deaths in the gas chambers. The building was then cleaned and disinfected, and the occupants of a neighboring block were bathed, de-loused, and given new clothing before being moved into the clean block. This process was repeated until all of the barracks were disinfected. Similar procedures were used for later epidemics of scarlet fever and other diseases, with infected prisoners being killed in the gas chambers. For these actions, Mengele was awarded the War Merit Cross (Second Class with swords) and was promoted in 1944 to First Physician of the Birkenau subcamp.[37]
