The main camp population grew from 18,000 in December 1942 to 30,000 in March 1943. In July or August 1941, Himmler briefed Höss about the 'Final Solution'. On September 3th, 1941, Soviet POWs at the Auschwitz main camp were used in trials of the poison gas Zyklon-B. This poison gas was produced by the German company "Degesch" (Deutsche Gesellschaft zur Schädlingsbekämpfung). The were gassed in underground cells in Block 11. After this trial, a gas chamber was rigged-up just outside the main camp and in February 1942, two temporary gas chambers opened at Birkenau. The crematories were built by the German company "Topf & son" located at Erfurt.
The hair of 12 year-old Lili had not been cut since her early childhood. When she and her family were forced to leave their home in Târgu-Mureş and move to the ghetto, Lili’s mother, Rivka, knew she would not be able to care properly for her daughter’s hair in the ghetto. Chopping off Lili’s two long, beautiful braids, she promised that they would be given to the neighbors for safekeeping.Within six weeks, Lili and her mother were murdered at Auschwitz.
By the end of September, the SS had started to develop plans to deport Jews to newly invaded Poland: the first steps towards the systematic murder that would follow. In Poland itself, thousands of Poles and Jews were rounded up and shot, early indications of the systematic murder that would follow. Alongside this, Hitler approved a new programme of euthanasia to exterminate the handicapped and mentally ill.
Despite, wide reporting of Holocaust atrocities including gas chambers, many prominent analysts doubted the authenticity of these reports. Prominently, Roger Allen, a member of the British Foreign Office discounted intelligence reports on the use of gas chambers in Polish extermination camps because he could “never understand what the advantage of a gas chamber over a simple machine gun or over starving people would be.”
When the selection process was complete, a work group of prisoners called the ‘Kanada Kommando’ collected the belongings of victims and took them to the ‘Kanada’ warehouse facility for sorting and transporting back to Germany. To the prisoners, Canada was a country that symbolised wealth. They, therefore, gave the ironic name Kanada (the German spelling of Canada) to the warehouse area as it was full of possessions, clothing and jewellery.
In the last months of Hitler’s Reich, as the German armies retreated, the Nazis began marching the prisoners still alive in the concentration camps to the territory they still controlled. The Germans forced the starving and sick Jews to walk hundreds of miles. Most died or were shot along the way. About a quarter of a million Jews died on the death marches.
Remarkably, there were instances of individual resistance and collective efforts at fighting back inside Auschwitz. Poles, Communists and other national groups established networks in the main camp. Some Jews assaulted Nazi guards, even at the entrance to the gas chambers. In October 1944, the Sonderkommando crew at crematoria IV revolted and destroyed the crematoria. It was never used again.
As the tide of World War II turned against the Nazis, they began a systematic plan to eliminate or "liquidate" the ghettos they had established, by a combination of mass murder on the spot and transferring the remaining residents to extermination camps. When the Nazis attempted to liquidate the Warsaw Ghetto on April 13, 1943, the remaining Jews fought back in what has become known as the Warsaw Ghetto Uprising. The Jewish resistance fighters held out against the entire Nazi regime for 28 days, longer than many European countries had been able to withstand Nazi conquest.
Oskar Schindler (28 April 1908 – 9 October 1974) was a German industrialist and a member of the Nazi Party who is credited with saving the lives of 1,200 Jews during the Holocaust by employing them in his enamelware and ammunitions factories in occupied Poland and the Protectorate of Bohemia and Moravia. He is the subject of the 1982 novel Schindler's Ark and its 1993 film adaptation, Schindler's List, which reflected his life as an opportunist initially motivated by profit, who came to show extraordinary initiative, tenacity, courage, and dedication to save the lives of his Jewish employees.
