Subject to harsh conditions—including inadequate shelter and sanitation—given minimal food, and worked to exhaustion, those who could no longer work faced transport back to Birkenau for gassing. German corporations invested heavily in the slave-labour industries adjacent to Auschwitz. In 1942 IG Farben alone invested more than 700 million Reichsmarks in its facilities at Auschwitz III.
The Germans turned again, fighting their way north to secure the coastal ports and annihilate the trapped armies. Miraculously, the German high command called a halt to the advance. The reprieve lasted 48 hours, long enough for the British to defend Dunkirk and evacuate what they could of the Allied armies. The Germans entered Paris on June 14. In a humiliating ceremony on June 22, France signed an armistice with Germany, leaving Britain to carry on the fight alone.
From 1933 until 1938, most of the people held in concentration camps were political prisoners and people the Nazis labeled as "asocial." These included the disabled, the homeless, and the mentally ill. After Kristallnacht in 1938, the persecution of Jews became more organized. This led to the exponential increase in the number of Jews sent to concentration camps.
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.
