The invasion conquered a huge area, including the Baltic states, Belarus, and west Ukraine. After the successful Battle of Smolensk in September 1941, Hitler ordered Army Group Centre to halt its advance to Moscow and temporarily divert its Panzer groups to aid in the encirclement of Leningrad and Kiev. This pause provided the Red Army with an opportunity to mobilise fresh reserves. The Moscow offensive, which resumed in October 1941, ended disastrously in December. On 7 December 1941, Japan attacked Pearl Harbor, Hawaii. Four days later, Germany declared war on the United States.
The prisoners put up various forms of resistance to the tyranny of the camp. Resistance organisations helped inmates to obtain medicine and food, documented Nazi crimes, supported attempts to escape and sabotage, tried to put political prisoners into positions of responsibility, and prepared for an uprising. A total of 667 prisoners escaped from Auschwitz, but 270 of them were caught in the vicinity of the camp and immediately executed. The best-known escape was that of two Slovak Jews, Alfred Wetzler and Walter Rosenberg (Rudolf Vrba) (link in Czech). They managed to cross into Slovakia and to tell Jewish leaders - and through them the world - about the terrible reality of Auschwitz, about which they wrote an extensive report. On the 7th of October 1944, there was an uprising by the Sonderkommando working in the gas chambers. The prisoners managed to destroy one of the gas chambers, and thus to hinder the extermination process. All the rebels died. A group of young female prisoners was also executed for having smuggled gunpowder to the rebels from the factory in Monowitz.
Annelies Marie Frank was born in Frankfurt on June 12, 1929 to Edith (née Holländer) and Otto Frank. The Frank family, which was affluent and socially active, had lived in the city since the seventeenth century. Otto and his two brothers served in the German army in World War I. In 1933, after the Nazi party came to power, the family moved to Amsterdam. For the first seven years, things were relatively quiet for the parents and their two daughters, Margot Betti (1926–1945) and her younger sister Anne, who attended the Montessori school until Germany invaded the Netherlands in May 1940.
Heinrich Himmler's Schutzstaffel (SS) took full control of the police and the concentration camps throughout Germany in 1934–35. Himmler expanded the role of the camps to hold so-called "racially undesirable elements", such as Jews, Gypsies/Romanis/Sintis, Serbs, Poles, disabled people, and criminals. The number of people in the camps, which had fallen to 7,500, grew again to 21,000 by the start of World War II and peaked at 715,000 in January 1945.
