Via the offices of the Sicherheitsdienst, the German security police, prison in Amsterdam, and the Westerbork transit camp, the people from the Secret Annex were put on transport to the Auschwitz-Birkenau concentration and extermination camp. The train journey took three days, during which Anne and over a thousand others were packed closely together in cattle wagons. There was little food and water and only a barrel for a toilet. 
Eventually, Birkenau held the majority of prisoners in the Auschwitz complex, including Jews, Poles, Germans, and Gypsies. Furthermore, it maintained the most degrading and inhumane conditions–inclusive of the complex’s gas chambers and crematoria. A third section, Auschwitz III, was constructed in nearby Monowitz, and consisted of a forced labor camp called Buna-Monowitz.
What would it mean for a writer not to hide the horror? There is no mystery here, only a lack of interest. To understand what we are missing, consider the work of another young murdered Jewish chronicler of the same moment, Zalmen Gradowski. Like Frank’s, Gradowski’s work was written under duress and discovered only after his death—except that Gradowski’s work was written in Auschwitz, and you have probably never heard of it.

At the bottom of the K.L. hierarchy, even below the criminals, were the Jews. Today, the words “concentration camp” immediately summon up the idea of the Holocaust, the genocide of European Jews by the Nazis; and we tend to think of the camps as the primary sites of that genocide. In fact, as Wachsmann writes, as late as 1942 “Jews made up fewer than five thousand of the eighty thousand KL inmates.” There had been a temporary spike in the Jewish inmate population in November, 1938, after Kristallnacht, when the Nazis rounded up tens of thousands of Jewish men. But, for most of the camps’ first decade, Jewish prisoners had usually been sent there not for their religion, per se, but for specific offenses, such as political dissent or illicit sexual relations with an Aryan. Once there, however, they found themselves subject to special torments, ranging from running a gantlet of truncheons to heavy labor, like rock-breaking. As the chief enemies in the Nazi imagination, Jews were also the natural targets for spontaneous S.S. violence—blows, kicks, attacks by savage dogs.
Nazism attempted to reconcile conservative, nationalist ideology with a socially radical doctrine. In so doing, it became a profoundly revolutionary movement—albeit a largely negative one. Rejecting rationalism, liberalism, democracy, the rule of law, human rights, and all movements of international cooperation and peace, it stressed instinct, the subordination of the individual to the state, and the necessity of blind and unswerving obedience to leaders appointed from above. It also emphasized the inequality of men and races and the right of the strong to rule the weak; sought to purge or suppress competing political, religious, and social institutions; advanced an ethic of hardness and ferocity; and partly destroyed class distinctions by drawing into the movement misfits and failures from all social classes. Although socialism was traditionally an internationalist creed, the radical wing of Nazism knew that a mass base existed for policies that were simultaneously anticapitalist and nationalist. However, after Hitler secured power, this radical strain was eliminated.
When I was eight years old Czechoslovakia broke apart and we became part of Hungary. That was when our problems started, because the Hungarians were allied with the Nazis. It was a difficult time for Jewish families, as suddenly the law no longer protected us and overnight we lost our civil rights. My father’s lumber business was confiscated and given to a non-Jew, and we received no compensation. Jewish children were thrown out of Hungarian schools, so right away we had no choice but to concentrate on hunkering down and trying not to bring attention to ourselves. We couldn’t ride the trains and we had to wear the yellow star. It was a free for all. With no law to protect us, it was common for Jews to get beaten up or thrown off the train.
Losses continued to mount after Stalingrad, leading to a sharp reduction in the popularity of the Nazi Party and deteriorating morale. [127] Soviet forces continued to push westward after the failed German offensive at the Battle of Kursk in the summer of 1943. By the end of 1943 the Germans had lost most of their eastern territorial gains.[128] In Egypt, Field Marshal Erwin Rommel's Afrika Korps were defeated by British forces under Field Marshal Bernard Montgomery in October 1942.[129] The Allies landed in Sicily in July 1943 and in Italy in September.[130] Meanwhile, American and British bomber fleets based in Britain began operations against Germany. Many sorties were intentionally given civilian targets in an effort to destroy German morale.[131] German aircraft production could not keep pace with losses, and without air cover the Allied bombing campaign became even more devastating. By targeting oil refineries and factories, they crippled the German war effort by late 1944.[132]
The first 'bunker', with two sealed rooms, operated from January 1942 to the end of that year. The second, with four air tight rooms, became redundant in the spring of 1943, but remained standing and was used again in the autumn of 1944 when extra 'capacity' was needed for the murder of Hungarian Jews and the liquidation of the ghettos. The second measured about 1.134 square feet. The victims murdered in the 'bunkers' were first obliged to undress in temporary wooden barracks erected nearby. Their bodies were taken out of the gas chambers and pushed to pits where they were burned in the open. Between January 1942 and March 1943, 175,000 Jews were gassed to death here, of whom 105,000 were killed from January to March 1943.
T he use of gas chambers was the most common method of mass murdering the Jews in the extermination camps. The Jews were herded into the gas chambers, then the camp personnel closed the doors, and either exhaust gas (in Belzec, Sobibor and Treblinka) or poison gas in the form of Zyclon B or A (in Majdanek and Auschwitz-Birkenau) was led into the gas chamber.
From German Nazi, a shortening of Nationalsozialist (“National Socialist”) (attested since 1903, as a shortening of national-sozial),[1] since in German the nati- in national /ˌnatsi̯oˈnaːl/ is approximately pronounced Nazi [ˈnäːtsi]; compare Sozi (“socialist”).[1] A homonymic term Nazi was in use before the rise of the NSDAP in Bavaria as a pet name for Ignaz and (by extension from that) a derogatory word for a backwards peasant, which may have influenced[2] the use of that abbreviation by the Nazis' opponents and its avoidance by the Nazis themselves.[1][3]
During the German invasion of the Soviet Union the Nazis began the first mass killings of Jews. Between June and September 1941, the Einsatzgruppen supported by local collaborators murdered hundreds of thousands of Jews across Latvia, Lithuania, Estonia and the Soviet Union. Having observed the killings, Adolf Eichmann ordered a more efficient method of killing the Jews of Europe be developed.
Even the distinction between guard and prisoner could become blurred. From early on, the S.S. delegated much of the day-to-day control of camp life to chosen prisoners known as Kapos. This system spared the S.S. the need to interact too closely with prisoners, whom they regarded as bearers of filth and disease, and also helped to divide the inmate population against itself. Helm shows that, in Ravensbrück, where the term “Blockova” was used, rather than Kapo, power struggles took place among prisoner factions over who would occupy the Blockova position in each barrack. Political prisoners favored fellow-activists over criminals and “asocials”—a category that included the homeless, the mentally ill, and prostitutes—whom they regarded as practically subhuman. In some cases, Kapos became almost as privileged, as violent, and as hated as the S.S. officers. In Ravensbrück, the most feared Blockova was the Swiss ex-spy Carmen Mory, who was known as the Black Angel. She was in charge of the infirmary, where, Helm writes, she “would lash out at the sick with the whip or her fists.” After the war, she was one of the defendants tried for crimes at Ravensbrück, along with S.S. leaders and doctors. Mory was sentenced to death but managed to commit suicide first.

At the end of the war, Europe had more than 40 million refugees,[156] its economy had collapsed, and 70 percent of its industrial infrastructure was destroyed.[157] Between twelve and fourteen million ethnic Germans fled or were expelled from central, eastern, and southeastern Europe to Germany.[158] The West German government estimated a death toll of 2.2 million civilians due to the flight and expulsion of Germans and through forced labour in the Soviet Union.[159] This figure remained unchallenged until the 1990s, when some historians put the death toll at 500,000–600,000 confirmed deaths.[160][161][162] In 2006, the German government reaffirmed its position that 2.0–2.5 million deaths occurred.[f]

When Anne’s sister, Margot, was faced with deportation (supposedly to a forced-labour camp), the Franks went into hiding on July 6, 1942, in the backroom office and warehouse of Otto Frank’s food-products business. With the aid of a few non-Jewish friends, among them Miep Gies, who smuggled in food and other supplies, the Frank family and four other Jews—Hermann and Auguste van Pels and their son, Peter, and Fritz Pfeffer—lived confined to the “secret annex.” During this time, Anne wrote faithfully in her diary, recounting day-to-day life in hiding, from ordinary annoyances to the fear of capture. She discussed typical adolescent issues as well as her hopes for the future, which included becoming a journalist or a writer. Anne’s last diary entry was written on August 1, 1944. Three days later the annex was discovered by the Gestapo, which was acting on a tip from Dutch informers.
After 1942, many small subcamps were set up near factories to provide forced labor. IG Farben established a synthetic rubber plant in 1942 at Monowitz concentration camp (Auschwitz III); other camps were set up next to airplane factories, coal mines and rocket propellant plants. Conditions were brutal and prisoners were often sent to the gas chambers or killed on site if they did not work quickly enough.
