I expect you will be interested to hear what it feels like to hide; well, all I can say is that I don't know myself yet. I don't think I shall ever feel really at home in this house but that does not mean that I loathe it here, it is more like being on vacation in a very peculiar boardinghouse. Rather a mad way of looking at being in hiding perhaps but that is how it strikes me.

“We had big gaps in our knowledge because most of the documentation about how the genocide was carried out on the ground was captured by the Soviet Red Army and wasn’t available until after the Cold War,” says White. The fall of the Soviet Union led to a feast of wartime bureaucratic records, allowing historians to realize how much leeway Nazi officials were given. It became readily clear that the number of Nazis involved in enacting the Final Solution was much larger than previously believed.
American soldiers stare down at a mass grave in Nordhausen concentration camp  © Originally a concentration camp for Polish political prisoners, Auschwitz was greatly expanded in 1941 with the addition of a much larger camp at nearby Birkenau. In all, Auschwitz-Birkenau and its sub-camps held 400,000 registered prisoners including 205,000 Jews, 137,000 Poles, 21,000 Gypsies, 12,000 Soviet POWs and 25,000 others (including a few British POWs). In this largest and worst of all the Nazi concentration camps, 210,000 prisoners died of starvation and abuse.

The deportations ... were the work of a much larger apparatus that had to deal with a host of constraints and requirements. The effort, as we shall see, was deemed necessary to accomplish the Final Solution on a European-wide scale.[p.273] 
Life in the camps was a living hell. As described by Judah Pilch in “Years of the Holocaust: The Factual Story,” which appears in The Jewish Catastrophe in Europe, a typical day in the life of a concentration camp inmate began at dawn, when they were roused from their barracks which housed 300-800 inmates each. Their “beds” were bunks of slatted wood two and three tiers high. Frequently three to four prisoners shared each bunk, not permitting space enough for them to stretch out for normal sleep. The inmates were organized into groups to go to the toilets, marched to a distribution center for a breakfast consisting of some bread and a liquid substitute for tea or coffee, and then sent out to work for 10-14 hours in mines, factories, and road or airfield building, often in sub-zero weather or the severe heat of summer. They were subjected to constant physical and emotional harassment and beating. The inmates’ food rations did not permit survival for very long. Those who resisted orders of the guards were shot on the spot. Numerous roll calls were held to assure that no prisoners had escaped. If one did attempt an escape, all of the inmates suffered for it.
As discrimination against Jews increased, German law required a legal definition of a Jew and an Aryan. Promulgated at the annual Nazi Party rally in Nürnberg on September 15, 1935, the Nürnberg Laws—the Law for the Protection of German Blood and German Honour and the Law of the Reich Citizen—became the centrepiece of anti-Jewish legislation and a precedent for defining and categorizing Jews in all German-controlled lands. Marriage and sexual relations between Jews and citizens of “German or kindred blood” were prohibited. Only “racial” Germans were entitled to civil and political rights. Jews were reduced to subjects of the state. The Nürnberg Laws formally divided Germans and Jews, yet neither the word German nor the word Jew was defined. That task was left to the bureaucracy. Two basic categories were established in November: Jews, those with at least three Jewish grandparents; and Mischlinge (“mongrels,” or “mixed breeds”), people with one or two Jewish grandparents. Thus, the definition of a Jew was primarily based not on the identity an individual affirmed or the religion he or she practiced but on his or her ancestry. Categorization was the first stage of destruction.
On October 23, 1941, S.S. head Heinrich Himmler issued an order down the Nazi chain of command which heralded a major change in Nazi policy with respect to the “Jewish problem.” Until then, the Nazis worked vigorously to encourage Jews to emigrate. The Madagascar Plan (see below) was one example of strategies which were formulated to remove Jews from Germany and its occupied lands. As is described in more detail in Chapter 11, many countries refused to accept Jewish refugees. This shift in policy resulted in the deportation of Jews to camps and ghettos in the East. The policy to “resettle” Jews to these ghettos and camps was a significant step in what was to become the “Final Solution” the systematic murder of millions of Jews.
The sins of the Soviets and the sins of Hellman and her Broadway deputies were, in Levin’s mind, identical. He set out to punish the man who had allowed all this to come to pass: Otto Frank had allied himself with the pundits of erasure; Otto Frank had stood aside when Levin’s play was elbowed out of the way. What recourse remained for a man so affronted and injured? Meyer Levin sued Otto Frank. It was as if, someone observed, a suit were being brought against the father of Joan of Arc. The bulky snarl of courtroom arguments resulted in small satisfaction for Levin: because the structure of the Hacketts’ play was in some ways similar to his, the jury detected plagiarism; yet even this limited triumph foundered on the issue of damages. Levin sent out broadsides, collected signatures, summoned a committee of advocacy, lectured from pulpits, took out ads, rallied rabbis and writers (Norman Mailer among them). He wrote “The Obsession,” his grandly confessional “J’Accuse,” rehearsing, in skirmish after skirmish, his fight for the staging of his own adaptation. In return, furious charges flew at him: he was a red-baiter, a McCarthyite. The term “paranoid” began to circulate. Why rant against the popularization and dilution that was Broadway’s lifeblood? “I certainly have no wish to inflict depression on an audience,” Kanin had argued. “I don’t consider that a legitimate theatrical end.” (So much for “Hamlet” and “King Lear.")
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.
In addition to active help, many clergymen also protested the mistreatment and deportations of Jews as violations of divine and human laws. The Catholic pastor of St. Hedwig’s Cathedral in Berlin, Bernard Lichtenburg, prayed publicly for the Jews until his arrest and death on the way to Dachau. The rescue work of priests of all Christian denominations is well-documented in postwar literature.

Theodor Holman wrote in reply to Sietse van der Hoek that the diary entry for 28 September 1942 proved conclusively the character's fictional origin.[citation needed] Jacqueline van Maarsen agreed,[citation needed] but Otto Frank assumed his daughter had her real acquaintance in mind when she wrote to someone of the same name.[citation needed] However, Kitty Egyedi said in an interview that she was flattered by the assumption, but doubted the diary was addressed to her:
One of the most famous Righteous Gentiles from the Holocaust, Schindler helped to save thousands of Polish Jews by shielding them as workers in his factories. Refering to them as his “Schindlerjuden,” Schindler ensured that the Jews in his factories worked but were also fed, no-one was beaten, and no-one was killed. It became an oasis of humanity in a desert of moral torpor. His story his immortalized in a film called "Schindler's List."
While there were only 23 main camps between 1933 to 1945, the Nazi regime established some 20,000 other camps used for forced labor, transit or temporary internment. During the Holocaust it is estimated that 6 million Jews were slaughtered along with, 3 million Soviet prisoners of war, 3 million Polish Catholics, 700,000 Serbians, 250,000 Gypsies, Sinti, and Lalleri, 80,000 Germans (for political reasons), 70,000 German handicapped, 12,000 homosexuals, and 2,500 Jehovah’s Witnesses.
This caught the interest of Contact Publishing in Amsterdam, who approached Otto Frank to submit a Dutch draft of the manuscript for their consideration. They offered to publish, but advised Otto Frank that Anne's candor about her emerging sexuality might offend certain conservative quarters, and suggested cuts. Further entries were also deleted. The diary – which was a combination of version A and version B – was published under the name Het Achterhuis. Dagbrieven van 14 juni 1942 tot 1 augustus 1944 (The Secret Annex. Diary Letters from June 14, 1942 to August 1, 1944) on June 25, 1947.[24] Otto Frank later discussed this moment, "If she had been here, Anne would have been so proud."[24] The book sold well; the 3000 copies of the first edition were soon sold out, and in 1950 a sixth edition was published.
In 1942, Auschwitz II (Birkenau), originally intended to house slave laborers, began to be used instead as a combined labor camp and extermination camp.[23][24] Prisoners were transported there by rail from all over German-occupied Europe, arriving in daily convoys.[25] By July 1942, SS doctors were conducting "selections" where incoming Jews were segregated, and those considered able to work were admitted into the camp while those deemed unfit for labor were immediately killed in the gas chambers.[26] The arrivals that were selected to die, about three-quarters of the total,[a] included almost all children, women with small children, pregnant women, all the elderly, and all of those who appeared (in a brief and superficial inspection by an SS doctor) to be not completely fit and healthy.[28][29]
