This debacle did not discourage Himmler and Pohl. On the contrary, with the coming of war, in 1939, S.S. ambitions for the camps grew rapidly, along with their prisoner population. On the eve of the war, the entire K.L. system contained only about twenty-one thousand prisoners; three years later, the number had grown to a hundred and ten thousand, and by January, 1945, it was more than seven hundred thousand. New camps were built to accommodate the influx of prisoners from conquered countries and then the tens of thousands of Red Army soldiers taken prisoner in the first months after Operation Barbarossa, the German invasion of the U.S.S.R.
These guards were the core of what became, a few years later, the much feared Death’s-Head S.S. The name, along with the skull-and-crossbones insignia, was meant to reinforce the idea that the men who bore it were not mere prison guards but front-line soldiers in the Nazi war against enemies of the people. Himmler declared, “No other service is more devastating and strenuous for the troops than just that of guarding villains and criminals.” The ideology of combat had been part of the DNA of Nazism from its origin, as a movement of First World War veterans, through the years of street battles against Communists, which established the Party’s reputation for violence. Now, in the years before actual war came, the K.L. was imagined as the site of virtual combat—against Communists, criminals, dissidents, homosexuals, Jehovah’s Witnesses, and Jews, all forces working to undermine the German nation.
A second roll call took place at seven in the evening after the long day's work.[118] Prisoners might be hanged or flogged in the course of it. If a prisoner was missing, the others had to remain standing until he or she was found or the reason for the absence discovered, even if it took hours. On 6 July 1940, roll call lasted 19 or 20 hours because of the escape of a Polish prisoner, Tadeusz Wiejowski; following another escape in 1941, a group of prisoners was sent to block 11 to be starved to death.[119] After roll call, prisoners were allowed to retire to their blocks for the night and receive their bread rations and water. Curfew was at nine o'clock. Inmates slept in long rows of brick or wooden bunks, lying in and on their clothes and shoes to prevent them from being stolen.[120] The wooden bunks had blankets and paper mattresses filled with wood shavings; in the brick barracks, inmates lay on straw.[121] According to Nyiszli:
Both national carrier PKP Intercity and regional line PolRegio provide rail service to Oświęcim station, with a travel time usually of an hour and 45 minutes from Kraków, and fifty minutes from Katowice. A bus can then be caught to Auschwitz I where the state museum is located (as there is a bus stop in front of the railway station), or you can walk there (approx 1.5 km) in about 20-25 minutes. If visitors decide to walk, leave the station, turn immediately right, and follow ul. Wyzwolenia for five minutes. At the first roundabout, follow the signs to the Muzeum Auschwitz, and turn left on ul. Stanisławy Leszczyńskiej.
On the morning of 4 August 1944, the Achterhuis was stormed by a group of German uniformed police (Grüne Polizei) led by SS-Oberscharführer Karl Silberbauer of the Sicherheitsdienst.[37] The Franks, van Pelses, and Pfeffer were taken to RSHA headquarters, where they were interrogated and held overnight. On 5 August they were transferred to the Huis van Bewaring (House of Detention), an overcrowded prison on the Weteringschans. Two days later they were transported to the Westerbork transit camp, through which by that time more than 100,000 Jews, mostly Dutch and German, had passed. Having been arrested in hiding, they were considered criminals and sent to the Punishment Barracks for hard labour.[38]
During the course of the war, the Nazis extracted considerable plunder from occupied Europe. Historian and war correspondent William L. Shirer writes: "The total amount of [Nazi] loot will never be known; it has proved beyond man's capacity to accurately compute."[290] Gold reserves and other foreign holdings were seized from the national banks of occupied nations, while large "occupation costs" were usually imposed. By the end of the war, occupation costs were calculated by the Nazis at 60 billion Reichsmarks, with France alone paying 31.5 billion. The Bank of France was forced to provide 4.5 billion Reichsmarks in "credits" to Germany, while a further 500,000 Reichsmarks were assessed against Vichy France by the Nazis in the form of "fees" and other miscellaneous charges. The Nazis exploited other conquered nations in a similar way. After the war, the United States Strategic Bombing Survey concluded Germany had obtained 104 billion Reichsmarks in the form of occupation costs and other wealth transfers from occupied Europe, including two-thirds of the gross domestic product of Belgium and the Netherlands.[290]
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.
Hitler spoke of Nazism being indebted to the success of Fascism's rise to power in Italy.[125] In a private conversation in 1941, Hitler said that "the brown shirt would probably not have existed without the black shirt", the "brown shirt" referring to the Nazi militia and the "black shirt" referring to the Fascist militia.[125] He also said in regards to the 1920s: "If Mussolini had been outdistanced by Marxism, I don't know whether we could have succeeded in holding out. At that period National Socialism was a very fragile growth".[125]
“Responsibility is extremely direct in face-to-face shootings,” Dwork says. “In gassing and cremation, each person is given only a small part.” Eventually, Germans took part only by tossing the cyanide pellets into the gas chambers. Everything else—herding prisoners into the chambers, ripping out gold fillings and loading corpses into the crematoria—was handled by groups of prisoners, known as Sonderkommandos.

Antisemitic legislation passed in 1933 led to the removal of all Jewish teachers, professors, and officials from the education system. Most teachers were required to belong to the Nationalsozialistischer Lehrerbund (NSLB; National Socialist Teachers League) and university professors were required to join the National Socialist German Lecturers.[349][350] Teachers had to take an oath of loyalty and obedience to Hitler, and those who failed to show sufficient conformity to party ideals were often reported by students or fellow teachers and dismissed.[351][352] Lack of funding for salaries led to many teachers leaving the profession. The average class size increased from 37 in 1927 to 43 in 1938 due to the resulting teacher shortage.[353]
A useful analogy requires that we move beyond a Google image search and truly interrogate history. If we do, we may arrive at the Camp de Rivesaltes, an ad hoc facility created from an empty military camp in southern France. Its first prisoners in 1938 were not Jews but Spanish refugees who had fought against Francisco Franco’s victorious fascists. They were fleeing inevitable persecution from the Spanish dictator. The goal of that temporary concentration camp was to prevent the further dispersion of the Spanish refugees and their settlement in France while a repatriation solution was found. It never was.
On 31 July 1941 Hermann Göring gave written authorization to SS-Obergruppenführer Reinhard Heydrich, Chief of the Reich Main Security Office (RSHA), to prepare and submit a plan for a "total solution of the Jewish question" in territories under German control and to coordinate the participation of all involved government organisations.[33] The resulting Generalplan Ost (General Plan for the East) called for deporting the population of occupied Eastern Europe and the Soviet Union to Siberia, for use as slave labour or to be murdered.[34]
After September 1939, with the beginning of the Second World War, concentration camps became places where millions of ordinary people were enslaved as part of the war effort, often starved, tortured and killed.[21] During the war, new Nazi concentration camps for "undesirables" spread throughout the continent. According to statistics by the German Ministry of Justice, about 1,200 camps and subcamps were run in countries occupied by Nazi Germany,[22] while the Jewish Virtual Library estimates that the number of Nazi camps was closer to 15,000 in all of occupied Europe[23][24] and that many of these camps were run for a limited amount of time before they were closed.[23] Camps were being created near the centers of dense populations, often focusing on areas with large communities of Jews, Polish intelligentsia, Communists or Romani. Since millions of Jews lived in pre-war Poland, most camps were located in the area of the General Government in occupied Poland, for logistical reasons. The location also allowed the Nazis to quickly remove the German Jews from within Germany proper.
