Various other German industrial enterprises, such as Krupp and Siemens-Schuckert, built factories with their own subcamps. There were around 40 or 50 such camps, 28 of them near industrial plants, each camp holding hundreds or thousands of prisoners. Designated as Aussenlager (external camp), Nebenlager (extension or subcamp), or Arbeitslager (labor camp), camps were built at Blechhammer, Jawiszowice, Jaworzno, Lagisze, Mysłowice, Trzebinia, and centers as far afield as the Protectorate of Bohemia and Moravia in Czechoslovakia. Industries with satellite camps included coal mines, foundries and other metal works, and chemical plants. Prisoners were also made to work in forestry and farming. Budy, for example, was a farming subcamp where prisoners worked 12-hour days, often in the fields, but sometimes tending animals, cleaning ponds, digging ditches, and making compost. Human ashes from the crematorium were mixed with sod and manure to make the compost. Incidents of sabotage to decrease production took place in several subcamps, including Charlottengrube, Gleiwitz II, and Rajsko.
A major tool of the Nazis' propaganda assault was the weekly Nazi newspaper Der Stürmer (The Attacker). At the bottom of the front page of each issue, in bold letters, the paper proclaimed, "The Jews are our misfortune!" Der Stürmer also regularly featured cartoons of Jews in which they were caricatured as hooked-nosed and apelike. The influence of the newspaper was far-reaching: by 1938 about a half million copies were distributed weekly.
In 2005, the historian Karl-Heinz Frieser summarized blitzkrieg as the result of German commanders using the latest technology in the most beneficial way according to traditional military principles and employing "the right units in the right place at the right time". Modern historians now understand blitzkrieg as the combination of the traditional German military principles, methods and doctrines of the 19th century with the military technology of the interwar period. Modern historians use the term casually as a generic description for the style of manoeuvre warfare practised by Germany during the early part of World War II, rather than as an explanation.[b] According to Frieser, in the context of the thinking of Heinz Guderian on mobile combined arms formations, blitzkrieg can be used as a synonym for modern manoeuvre warfare on the operational level.
During the Holocaust, concentration camp prisoners received tattoos only at one location, Auschwitz. Incoming prisoners were assigned a camp serial number which was sewn to their prison uniforms. Only those prisoners selected for work were issued serial numbers; those prisoners sent directly to the gas chambers were not registered and received no tattoos.
Directive control was a fast and flexible method of command. Rather than receiving an explicit order, a commander would be told of his superior's intent and the role which his unit was to fill in this concept. The exact method of execution was then a matter for the low-level commander to determine as best fit the situation. Staff burden was reduced at the top and spread among commands more knowledgeable about their own situation. In addition, the encouragement of initiative at all levels aided implementation. As a result, significant decisions could be effected quickly and either verbally or with written orders a few pages in length.
At dawn on 10 May, the Germans began an invasion of Belgium and the Netherlands. Accordingly, convinced that they were facing a repeat of the German strategy of 1914, Allied commanders moved the bulk of their forces from the Franco-Belgian border into defensive positions within Belgium to await the continuation of the German attack. In so doing, they fell right into Hitler's trap.
The St. Louis arrived in Havana harbor on May 27th. Of the 937 passengers on board, only 28 passengers were allowed into Cuba. 22 of these passengers were Jewish and had valid U.S. visas, 4 were Spanish citizens and 2 were Cuban nationals, all with valid documents. This story gained a lot of publicity; it was spread throughout Europe and the United States. The U.S. newspapers reported the story compassionately, but only a handful suggested that the refugees should come to the United States. The United States government decided not to take the steps to permit the passengers into the country.
After attending primary and secondary school, Schindler enrolled in a technical school, from which he was expelled in 1924 for forging his report card. He later graduated, but did not take the Abitur exams that would have enabled him to go to college or university. Instead, he took courses in Brno in several trades, including chauffeuring and machinery, and worked for his father for three years. A fan of motorcycles since his youth, Schindler bought a 250-cc Moto Guzzi racing motorcycle and competed recreationally in mountain races for the next few years.
