Once Germany took over Poland in 1939, it created forced-labor camps. Thousands of prisoners died from working conditions, exhaustion, and starvation. After the outbreak of World War II, the number of concentration camps increased exponentially. The number of prisoners of war camps also rose, but after the first years of the war most were converted into concentration camps. Nazis forcibly relocated Jews from ghettos to concentration camps.

In most ghettos, Nazis ordered the Jews to establish a Judenrat (Jewish council) to administer Nazi demands and to regulate the internal life of the ghetto. The Nazis routinely ordered deportations from the ghettos. In some of the large ghettos, 1,000 people per day were sent by rail to concentration and extermination camps. To get them to cooperate, the Nazis told the Jews they were being transported elsewhere for labor.
Blitzkrieg tactics often affected civilians in a way perceived by some to be negative — sometimes intentionally, and sometimes not. Whereas more traditional conflict resulted in a well-defined, slow moving front line, giving civilians time to be evacuated to safety, the new approach did not provide for this luxury. As a result, civilian casualties, as a percentage of the total, increased substantially. Furthermore, in the total war doctrine, civilians were explicitly targeted (as in the Allied bombing of Dresden), in an effort to break the morale of the citizenry of a country in order to frustrate attempts at production, and ultimately support for the cause over which the war was fought.
The women's concentration camp (Frauenkonzentrationslager or FKL) was established in August 1942, in 15 brick and 15 wooden barracks in sector BIa (Bauabschnitt Ia) in Auschwitz II, when 13,000 women were transferred from Auschwitz I. The camp was later extended into sector BIb, and by October 1943 it held 32,066 women. Conditions in the camp were so poor that, in October 1942, when a group of male prisoners arrived to set up an infirmary, their first task, according to researchers from the Auschwitz museum, was to distinguish the corpses from the women who were still alive.[123] Gisella Perl, a Romanian-Jewish gynecologist and inmate of the women's camp, wrote in 1948:
The Luftwaffe did end up with an air force consisting mainly of relatively short-range aircraft, but this does not prove that the German air force was solely interested in ’tactical’ bombing. It happened because the German aircraft industry lacked the experience to build a long-range bomber fleet quickly, and because Hitler was insistent on the very rapid creation of a numerically large force. It is also significant that Germany's position in the centre of Europe to a large extent obviated the need to make a clear distinction between bombers suitable only for ’tactical’ and those necessary for strategic purposes in the early stages of a likely future war.[141]
^ Nothing appeared in Luftwaffe 'doctrine' stipulating "terror" as a major operational factor. The method of "terror", was denied to German aerial operations (and strategic bombing methods) by the Luftwaffe field manual The Conduct of Air Operations, Regulation 16, issued in 1935 (Corum 1992, pp. 167–169). Regulation 16 denied "terror" operations against civilians, and it was not until 1942 when indiscriminate "terror" operations, in which terror and civilian casualties become the primary target, took place (Corum 1997, pp. 7, 143).

The Allied offensive in central France, spearheaded by armored units from George S. Patton's Third Army, used breakthrough and penetration techniques that were essentially identical to Guderian's prewar "armoured idea." Patton acknowledged that he had read both Guderian and Rommel before the war, and his tactics shared the traditional cavalry emphasis on speed and attack. A phrase commonly used in his units was "haul ass and bypass."
Treatment inside the concentration camps were horrible. Prisoners were given tiny rations of food and forced into physical labor. They often slept more than three to a bed without pillows or blankets, even in the winter months. In many concentration camps, Nazi doctors conducted medical experiments on prisoners against their will, in many cases killing the prisoners in the process.
A symbol of innocence in the movie, the little girl in the red coat who appears during the liquidation of the ghetto in the movie was based on a real person. In the film, the little girl is played by actress Oliwia Dabrowska, who—at the age of three—promised Spielberg that she would not watch the film until she was 18 years old. She allegedly watched the movie when she was 11, breaking her promise, and spent years rejecting the experience. Later, she told the Daily Mail, “I realized I had been part of something I could be proud of. Spielberg was right: I had to grow up to watch the film.”
In June 1945 the Soviet authorities took over Auschwitz I and converted it into a POW camp for German prisoners. The hospital had to move beyond the camp perimeter into former administrative buildings, where it functioned until October 1945.[253] Many of the barracks at Birkenau were taken apart by civilians, who used the materials to rebuild their own homes, which had been levelled out in the construction of Auschwitz II. The poorest residents sifted the crematoria ashes in search of nuggets from melted gold, before warning shots were fired.[254] The POW camp for German prisoners of war was used until 1947 by the Soviet NKVD (People's Commissariat for Internal Affairs).[255] The NKVD and its Polish counterpart, the MBP, used the Auschwitz Neu-Dachs sub-camp at Jaworzno to the north of Oświęcim as a concentration camp from 1945 to 1956.[256] The Soviets dismantled and exported the IG Farben factories to the USSR.[257] Meanwhile, Soviet and Polish investigators worked to document the war crimes of the SS.[258] After the site became a museum in 1947, exhumation work lasted for more than a decade.[184]
Schindler was the eldest of two children born to a farm machinery manufacturer and his wife. Svitavy, where the family lived, was located in the Sudetenland, and, though the region passed from the Austrian Empire to Czechoslovakia in 1918, the Schindlers were ethnically German. After leaving school in 1924, Schindler sold farm equipment for his father, during which time he met his future wife, Emilie, whom he married in 1928. He took a variety of odd jobs, including running a driving school, before enlisting for a stint in the Czechoslovak army. Schindler then briefly lived in Berlin before returning to Czechoslovakia to start a poultry farm, which he soon abandoned. A self-professed sybarite, he spent much of his time drinking and philandering.

The concepts associated with the term "Blitzkrieg" - deep penetrations by armour, large encirclements, and combined arms attacks - were largely dependent upon terrain and weather conditions. Where the ability for rapid movement across "tank country" was not possible, armoured penetrations were often avoided or resulted in failure. Terrain would ideally be flat, firm, unobstructed by natural barriers or fortifications, and interspersed with roads and railways. If it was instead hilly, wooded, marshy, or urban, armour would be vulnerable to infantry in close-quarters combat and unable to break out at full speed. Additionally, units could be halted by mud ( thawing along the Eastern Front regularly slowed both sides) or extreme snow. Artillery observation and aerial support was also naturally dependent on weather.
Our perception of land operations in the Second World War has...been distorted by an excessive emphasis upon the hardware employed. The main focus of attention has been the tank and the formations that employed it, most notably the (German) panzer divisions. Despite the fact that only 40 of the 520 German divisions that saw combat were panzer divisions (there were also an extra 24 motorised/panzergrenadier divisions), the history of German operations has consistently almost exclusively been written largely in terms of blitzkrieg and has concentrated almost exclusively upon the exploits of the mechanized formations. Even more misleadingly, this presentation of ground combat as a largely armored confrontation has been extended to cover Allied operations, so that in the popular imagination the exploits of the British and Commonwealth Armies, with only 11 armored divisions out of 73 (that saw combat), and of the Americans in Europe, with only 16 out of 59, are typified by tanks sweeping around the Western Desert or trying to keep up with Patton in the race through Sicily and across northern France. Of course, these armored forces did play a somewhat more important role in operations than the simple proportions might indicate, but it still has to be stressed that they in no way dominated the battlefield or precipitated the evolution of completely new modes of warfare.
Initially, Schindler was mostly interested in the money-making potential of the business and hired Jews because they were cheaper than Poles—the wages were set by the occupying Nazi regime.[38] Later he began shielding his workers without regard for cost.[39] The status of his factory as a business essential to the war effort became a decisive factor enabling him to help his Jewish workers. Whenever Schindlerjuden (Schindler Jews) were threatened with deportation, he claimed exemptions for them. He claimed wives, children, and even people with disabilities were necessary mechanics and metalworkers.[39] On one occasion, the Gestapo came to Schindler demanding that he hand over a family that possessed forged identity papers. "Three hours after they walked in," Schindler said, "two drunk Gestapo men reeled out of my office without their prisoners and without the incriminating documents they had demanded."[40]
