Never one to miss a chance to make money, he marched into Poland on the heels of the SS. He dived headfirst into the black-market and the underworld and soon made friends with the local Gestapo bigwigs, softening them up with women, money and illicit booze. His newfound connections helped him acquire a factory which he ran with the cheapest labor around: Jewish.
The first experimental gassing took place in September 1941, when Lagerführer Karl Fritzsch, at the instruction of Rudolf Höss, killed a group of Soviet prisoners of war by throwing Zyklon B crystals into their basement cell in block 11 of Auschwitz I. A second group of 600 Soviet prisoners of war and around 250 sick Polish prisoners was gassed on 3–5 September.[29] The morgue was later converted to a gas chamber able to hold at least 700–800 people.[30] Zyklon B was dropped into the room through slits in the ceiling.[28] In the view of Filip Müller, one of the Sonderkommando who worked in crematorium I, tens of thousands of Jews were killed there from France, Holland, Slovakia, Upper Silesia, Yugoslavia, and from the Theresienstadt, Ciechanow, and Grodno ghettos.[31] The last inmates to be gassed in Auschwitz I, in December 1942, were 300–400 members of the Auschwitz II Sonderkommando, who had been forced to dig up that camp's mass graves, thought to hold 100,000 corpses, and burn the remains.[32]
Blitzkrieg sought decisive actions at all times. To this end, the theory of a schwerpunkt (focal point) developed; it was the point of maximum effort. Panzer and Luftwaffe forces were used only at this point of maximum effort whenever possible. By local success at the schwerpunkt, a small force achieved a breakthrough and gained advantages by fighting in the enemy's rear. It is summarized by Guderian as "Nicht kleckern, klotzen!" ("Don't tickle, smash!")
Soviet civilian populations in the occupied areas were heavily persecuted.[438] Villages throughout the Soviet Union were destroyed by German troops.[439] Germans rounded up civilians for forced labor in Germany and caused famine by taking foodstuffs.[440] In Belarus, Germany imposed a regime that deported some 380,000 people for slave labor and killed hundreds of thousands of civilians. Over 600 villages had their entire populations killed, and at least 5,295 Belarusian settlements were destroyed by the Germans. According to Timothy Snyder, of "the nine million people who were in the territory of Soviet Belarus in 1941, some 1.6 million were killed by the Germans in actions away from battlefields, including about 700,000 prisoners of war, 500,000 Jews, and 320,000 people counted as partisans (the vast majority of whom were unarmed civilians)".[441] The United States Holocaust Memorial Museum has estimated that 3.3 million of 5.7 million Soviet POWs died in German custody.[442] The death rates decreased as the POWs were needed to help the German war effort; by 1943, half a million had been deployed as slave labor.[409]
Frieser wrote that after the failure of the Schlieffen Plan in 1914, the German army concluded that decisive battles were no longer possible in the changed conditions of the twentieth century. Frieser wrote that the Oberkommando der Wehrmacht (OKW), which was created in 1938 had intended to avoid the decisive battle concepts of its predecessors and planned for a long war of exhaustion (ermattungskrieg). It was only after the improvised plan for the Battle of France in 1940 was unexpectedly successful, that the German General Staff came to believe that vernichtungskrieg was still feasible. German thinking reverted to the possibility of a quick and decisive war for the Balkan Campaign and Operation Barbarossa.[111]
Also in 1993, the United States Holocaust Memorial Council posthumously presented the Museum's Medal of Remembrance to Schindler. Rarely presented, this medal honors deserving recipients for extraordinary deeds during the Holocaust and in the cause of Remembrance. Emilie Schindler accepted the medal on behalf of her ex-husband at a ceremony in the Museum's Hall of Remembrance.
Germany’s plans to attack the USSR were heavily influenced by Adolf Hitler’s racist, anti-Semitic and anti-Bolshevik postulates, which he had largely formulated much earlier in his agenda-setting book Mein Kampf. Joseph Stalin failed to fully take into account the highly ideological nature of Hitler’s political and military-strategic thinking; this led to mistakes in interpreting the Third Reich’s plans vis-a-vis the Soviet Union.

Those Jews selected for work were sent to a separate building for registration. Prisoners would be registered, before undressing, placing their clothes on a hook, together with their shoes. They would then be tattooed with a registration number, shaved of all body hair, disinfected and forced through showers that were either extremely cold or painfully hot.

Today, the word Auschwitz has become synonymous with terror, genocide, and The Holocaust. The site, though partially destroyed by the retreating Nazi’s in 1945, has been established as a museum to help future generations understand the atrocities committed within its fences. By 2011, more than 30 million people had visited the camp, and during 2014 a record number of 1.5 million people visited the Auschwitz complex and museum. Spokespeople for the museum said that from January to April 2015, over 250,000 people visited Auschwitz, marking a 40% increase over the already large numbers from the previous year. Authorities in charge of the site began to urge people to book their visit to Auschwitz online ahead of time to prevent them from having to turn people away.
Romania implemented anti-Jewish measures in May and June 1940 as part of its efforts towards an alliance with Germany. Jews were forced from government service, pogroms were carried out, and by March 1941 all Jews had lost their jobs and had their property confiscated.[169] After Romania joined the invasion of the Soviet Union in June 1941, at least 13,266 Jews were killed in the Iași pogrom,[170] and Romanian troops carried out massacres in Romanian-controlled territory, including the Odessa massacre of 20,000 Jews in Odessa in late 1941. Romania also set up concentration camps under its control in Transnistria, where 154,000–170,000 Jews were deported from 1941 to 1943.[169]
In early 1942, mass exterminations were moved to two provisional gas chambers (the "red house" and "white house", known as bunkers 1 and 2) in Auschwitz II, while the larger crematoria (II, III, IV, and V) were under construction. Bunker 2 was temporarily reactivated from May to November 1944, when large numbers of Hungarian Jews were gassed.[161] In summer 1944 the combined capacity of the crematoria and outdoor incineration pits was 20,000 bodies per day.[162] A planned sixth facility—crematorium VI—was never built.[163] Prisoners were transported from all over German-occupied Europe by rail, arriving in daily convoys.[164] By July 1942, the SS were conducting "selections". Incoming Jews were segregated; those deemed able to work were sent to the selection officer's right and admitted into the camp, and those deemed unfit for labor were sent to the left and immediately gassed.[165] The group selected to die, about three-quarters of the total,[c] included almost all children, women with small children, the elderly, and all those who appeared on brief and superficial inspection by an SS doctor not to be fit for work.[167]
The government defined a Jewish person as someone with three or four Jewish grandparents, not someone who had religious convictions. This meant that people who had never practiced, or hadn’t practiced Judaism in many years, or even converted to Christianity were subjected to persecution. Although anti-semitism was pervasive in 1930s Germany, these restrictions frequently extended to any person the Nazis considered to be “non-Aryan”.
Some Auschwitz prisoners were subjected to inhumane medical experimentation. The chief perpetrator of this barbaric research was Josef Mengele (1911-79), a German physician who began working at Auschwitz in 1943. Mengele, who came to be known as the “Angel of Death,” performed a range of experiments on detainees. For example, in an effort to study eye color, he injected serum into the eyeballs of dozens of children, causing them excruciating pain. He also injected chloroform into the hearts of twins, to determine if both siblings would die at the same time and in the same manner.
Schindler's ties with the Abwehr and his connections in the Wehrmacht and its Armaments Inspectorate enabled him to obtain contracts to produce enamel cookware for the military.[31] These connections also later helped him protect his Jewish workers from deportation and death.[32] As time went on, Schindler had to give Nazi officials ever larger bribes and gifts of luxury items obtainable only on the black market to keep his workers safe.[33] Bankier, a key black market connection, obtained goods for bribes as well as extra materials for use in the factory.[34] Schindler himself enjoyed a lavish lifestyle and pursued extramarital relationships with his secretary, Viktoria Klonowska, and Eva Kisch Scheuer, a merchant specialising in enamelware from DEF.[35] Emilie Schindler visited for a few months in 1940 and moved to Kraków to live with Oskar in 1941.[36][37]
