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. Otto Frank later discussed this moment, "If she had been here, Anne would have been so proud." The book sold well; the 3000 copies of the first edition were soon sold out, and in 1950 a sixth edition was published.
I followed Freund up a short slope and past a trench where prisoners had been lined up and shot. It was now a barely perceptible dip in the loam. Freund stepped gingerly around it. In the distance, a train whistle howled, followed by the huff of a train, shuddering over tracks that had carried prisoners to their deaths decades earlier. Freund waited for it to pass. He recalled that he’d spent nearly a month researching the site—but “a few days,” he said, “is plenty of time to think about how many people died here, the amount of blood spilled.”
In October 1941, Himmler authorized SS General Odilo Globocnik (SS and police leader for the Lublin District of the Generalgouvernement) to implement a plan to systematically murder all Jews residing in the Generalgouvernement. In 1942, this project received the code name "Operation Reinhard" (Einsatz Reinhard), a reference to Heydrich (who had been authorized to manage the implementation of the "Final Solution" and who was assassinated by Czech agents in May 1942 in Prague).
The Final Solution (German: Endlösung) or the Final Solution to the Jewish Question (German: die Endlösung der Judenfrage, pronounced [diː ˈɛntˌløːzʊŋ deːɐ̯ ˈjuːdn̩ˌfʁaːɡə]) was a Nazi plan for the genocide of Jews during World War II. The "Final Solution of the Jewish Question" was the official code name for the murder of all Jews within reach, which was not restricted to the European continent. This policy of deliberate and systematic genocide starting across German-occupied Europe was formulated in procedural and geo-political terms by Nazi leadership in January 1942 at the Wannsee Conference held near Berlin, and culminated in the Holocaust, which saw the killing of 90% of Polish Jews, and two thirds of the Jewish population of Europe.
The unstoppable Allied military advance continued and on July 24, 1944, Soviet troops liberated the first camp, Majdanek in eastern Poland, where over 360,000 had died. As the Soviet Army neared Auschwitz, Himmler ordered the complete destruction of the gas chambers. Throughout Hitler's crumbling Reich, the SS now began conducting death marches of surviving concentration camp inmates away from outlying areas, including some 66,000 from Auschwitz. Most of the inmates on these marches either dropped dead from exertion or were shot by the SS when they failed to keep up with the column.
Construction work on the first killing centre at Bełżec in occupied Poland began in October 1941, three months before the Wannsee Conference. The new facility was operational by March the following year. By mid-1942, two more death camps had been built on Polish lands: Sobibór operational by May 1942, and Treblinka operational in July. From July 1942, the mass murder of Polish and foreign Jews took place at Treblinka as part of Operation Reinhard, the deadliest phase of the Final Solution. More Jews were killed at Treblinka than at any other Nazi extermination camp apart from Auschwitz. By the time the mass killings of Operation Reinhard ended in 1943, roughly two million Jews in German-occupied Poland had been murdered. The total number of people killed in 1942 in Lublin/Majdanek, Bełżec, Sobibór, and Treblinka was 1,274,166 by Germany's own estimation, not counting Auschwitz II Birkenau nor Kulmhof. Their bodies were buried in mass graves initially. Both Treblinka and Bełżec were equipped with powerful crawler excavators from Polish construction sites in the vicinity, capable of most digging tasks without disrupting surfaces. Although other methods of extermination, such as the cyanic poison Zyklon B, were already being used at other Nazi killing centres such as Auschwitz, the Aktion Reinhard camps used lethal exhaust gases from captured tank engines.
The Nazis frequently used euphemistic language to disguise the true nature of their crimes. They used the term “Final Solution” to refer to their plan to annihilate the Jewish people. It is not known when the leaders of Nazi Germany definitively decided to implement the "Final Solution." The genocide, or mass destruction, of the Jews was the culmination of a decade of increasingly severe discriminatory measures.
At Auschwitz, a large new camp was already under construction to be known as Auschwitz II (Birkenau). This would become the future site of four large gas chambers to be used for mass extermination. The idea of using gas chambers originated during the Euthanasia Program, the so-called "mercy killing" of sick and disabled persons in Germany and Austria by Nazi doctors.
In his 1965 essay "Command and Compliance", which originated in his work as an expert witness for the prosecution at the Frankfurt Auschwitz Trials, the German historian Hans Buchheim wrote there was no coercion to murder Jews and others, and all who committed such actions did so out of free will. Buchheim wrote that chances to avoid executing criminal orders "were both more numerous and more real than those concerned are generally prepared to admit", and that he found no evidence that SS men who refused to carry out criminal orders were sent to concentration camps or executed. Moreover, SS rules prohibited acts of gratuitous sadism, as Himmler wished for his men to remain "decent"; acts of sadism were carried out on the initiative of those who were either especially cruel or wished to prove themselves ardent National Socialists. Finally, he argued that those of a non-criminal bent who committed crimes did so because they wished to conform to the values of the group they had joined and were afraid of being branded "weak" by their colleagues if they refused.
In early 1943, encouraged by von Verschuer, Mengele applied to transfer to the concentration camp service. 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, 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. 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.
