The digging got underway the first night in February 1944, in a storeroom at the back of the bunker. To disguise their efforts, the prisoners erected a fake wall over the tunnel’s entrance, with “two boards hanging on loose nails that would come out with a good tug, making it possible to pass through,” Farber recalled in The Complete Black Book of Russian Jewry, a compilation of eyewitness testimonies, letters and other documents of the Nazi campaign against Jews in Eastern Europe published in part in 1944 and translated into English in 2001.
Several scholars have suggested that the Final Solution began in the newly formed district of Bezirk Bialystok. The German army took over Białystok within days. On Friday, 27 June 1941, the Reserve Police Battalion 309 arrived in the city and set the Great Synagogue on fire with hundreds of Jewish men locked inside. The burning of the synagogue was followed by a frenzy of killings both inside the homes around the Jewish neighbourhood of Chanajki, and in the city park, lasting until night time. The next day, some 30 wagons of dead bodies were taken to mass graves. As noted by Browning, the killings were led by a commander "who correctly intuited and anticipated the wishes of his Führer" without direct orders. For reasons unknown, the number of victims in the official report by Major Weis was cut in half. The next mass shooting of Polish Jews within the newly formed Reichskommissariat Ostland took place in two days of 5–7 August in occupied Pińsk, where over 12,000 Jews died at the hands of Waffen SS, not the Einsatzgruppen. An additional 17,000 Jews perished there in a ghetto uprising crushed a year later with the aid of Belarusian Auxiliary Police.
In her diary, Anne wrote of her very close relationship with her father, lack of daughterly love for her mother (with whom she felt she had nothing in common), and admiration for her sister's intelligence and sweet nature. She did not like the others much initially, particularly Auguste van Pels and Fritz Pfeffer (the latter shared her room). She was at first unimpressed by the quiet Peter; she herself was something of a self-admitted chatterbox (a source of irritation to some of the others). As time went on, however, she and Peter became very close, though she remained uncertain in what direction their relationship would develop.
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.
The impact of the Holocaust varied from region to region and from year to year in the 21 countries that were directly affected. Nowhere was the Holocaust more intense and sudden than in Hungary. What took place over several years in Germany occurred over 16 weeks in Hungary. Entering the war as a German ally, Hungary had persecuted its Jews but not permitted the deportation of Hungarian citizens. In 1941 foreign Jewish refugees were deported from Hungary and were shot by Germans in Kam’yanets-Podilskyy, Ukraine. After Germany invaded Hungary on March 19, 1944, the situation changed dramatically. By mid-April the Nazis had confined Jews to ghettos. On May 15, deportations began, and over the next 55 days the Nazis deported more than 437,000 Jews from Hungary to Auschwitz on 147 trains.
Before the war, Mengele had received doctorates in anthropology and medicine, and began a career as a researcher. He joined the Nazi Party in 1937 and the SS in 1938. He was assigned as a battalion medical officer at the start of World War II, then transferred to the Nazi concentration camps service in early 1943 and assigned to Auschwitz, where he saw the opportunity to conduct genetic research on human subjects. His subsequent experiments focused primarily on twins, with little regard for the health or safety of the victims.
