Entering conquered Soviet territories alongside the Wehrmacht (the German armed forces) were 3,000 men of the Einsatzgruppen (“Deployment Groups”), special mobile killing units. Their task was to murder Jews, Soviet commissars, and Roma in the areas conquered by the army. Alone or with the help of local police, native anti-Semitic populations, and accompanying Axis troops, the Einsatzgruppen would enter a town, round up their victims, herd them to the outskirts of the town, and shoot them. They killed Jews in family units. Just outside Kiev, Ukraine, in the ravine of Babi Yar, an Einsatzgruppe killed 33,771 Jews on September 28–29, 1941. In the Rumbula Forest outside the ghetto in Riga, Latvia, 25,000–28,000 Jews were shot on November 30 and December 8–9. Beginning in the summer of 1941, Einsatzgruppen murdered more than 70,000 Jews at Ponary, outside Vilna (now Vilnius) in Lithuania. They slaughtered 9,000 Jews, half of them children, at the Ninth Fort, adjacent to Kovno (now Kaunas), Lithuania, on October 28.
This was so awful! How can ANYONE disregard this as DUMB?!? Who the hell ARE you ppl to think of this that way? You weren't there...don't judge it...this is a place of evil and murder. Millions of innocent ppl killed everyday for YEARS!! Anyone who thinks this camp is not worth hearing about..seriously has no LIFE! No HEART! Nothing...you would be considered lowlife..heartless ppl..how could you... To all who actually CARE about what happened...thank you. We will never forget.....
Despite the term blitzkrieg being coined by journalists during the Invasion of Poland of 1939, historians Matthew Cooper and J. P. Harris have written that German operations during it were consistent with traditional methods. The Wehrmacht strategy was more in line with Vernichtungsgedanken a focus on envelopment to create pockets in broad-front annihilation. Panzer forces were dispersed among the three German concentrations with little emphasis on independent use, being used to create or destroy close pockets of Polish forces and seize operational-depth terrain in support of the largely un-motorized infantry which followed.[81]
The enormous might of Hitler’s Wehrmacht in 1941 lay in the quality of its personnel, its optimized organizational decisions (regarding operations in tank groups, air fleets and other formations), its top-notch operational art and tactics and in the fact that many of its weapons systems and military technologies were well matched to the blitzkrieg’s objectives.

When the Soviet army entered Auschwitz on January 27, they found approximately 7,600 sick or emaciated detainees who had been left behind. The liberators also discovered mounds of corpses, hundreds of thousands of pieces of clothing and pairs of shoes and seven tons of human hair that had been shaved from detainees before their liquidation. According to some estimates, between 1.1 million to 1.5 million people, the vast majority of them Jews, died at Auschwitz during its years of operation. An estimated 70,000 to 80,000 Poles perished at the camp, along with 19,000 to 20,000 Gypsies and smaller numbers of Soviet prisoners of war and other individuals.
The Auschwitz concentration camp (Konzentrationslager Auschwitz) was a complex of over 40 concentration and extermination camps built and operated by Nazi Germany in occupied Poland during World War II and the Holocaust. It consisted of Auschwitz I, the main camp (Stammlager) and administrative headquarters, in Oświęcim; Auschwitz II–Birkenau, a combined concentration/extermination camp three kilometers away in Brzezinka; Auschwitz III–Monowitz, a labor camp seven kilometers from Auschwitz I, set up to staff an IG Farben synthetic-rubber factory; and dozens of other subcamps.[2]

The Holocaust was the murder by Nazi Germany of six million Jews. While the Nazi persecution of the Jews began in 1933, the mass murder was committed during World War II. It took the Germans and their accomplices four and a half years to murder six million Jews. They were at their most efficient from April to November 1942 – 250 days in which they murdered some two and a half million Jews. They never showed any restraint, they slowed down only when they began to run out of Jews to kill, and they only stopped when the Allies defeated them. More...

December 11, 1941 - Hitler declares war on the United States. President Roosevelt then asks Congress for a declaration of war on Germany saying, "Never before has there been a greater challenge to life, liberty and civilization." The U.S.A. then enters the war in Europe and will concentrate nearly 90 percent of its military resources to defeat Hitler.
Around 50,000 German gay men were jailed between 1933 and 1945, and 5,000–15,000 are estimated to have been sent to concentration camps. It is not known how many died during the Holocaust.[413][449] James Steakley writes that what mattered in Germany was criminal intent or character, rather than acts, and the "gesundes Volksempfinden" ("healthy sensibility of the people") became the guiding legal principle.[450] In 1936, Himmler created the Reich Central Office for the Combating of Homosexuality and Abortion.[451] The Gestapo raided gay bars, tracked individuals using the address books of those they arrested, used the subscription lists of gay magazines to find others, and encouraged people to report suspected homosexual behavior and to scrutinize the behavior of their neighbors.[450] Lesbians were left relatively unaffected;[413] the Nazis saw them as "asocials", rather than sexual deviants.[452] Gay men convicted between 1933 and 1944 were sent to camps for "rehabilitation", where they were identified by pink triangles.[450] Hundreds were castrated, sometimes "voluntarily" to avoid criminal sentences.[453] Steakley writes that the full extent of gay suffering was slow to emerge after the war. Many victims kept their stories to themselves because homosexuality remained criminalized in postwar Germany.[450]
After the arrival of a transport at the ramp in Birkenau, the process known as selection took place. SS officers decided who would be taken to work, and who would be sent directly to the gas chambers. Often it was mere chance or the mood of the SS officer that decided whether someone died immediately or had a hope of survival. The prisoners selected for slave labour were sent to one of the many auxiliary camps at Auschwitz or elsewhere in the Nazi concentration camp system. Their aim was „Vernichtung durch Arbeit“ - extermination through labour.
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."
The Nazis considered Jews to be the main danger to Germany. Jews were the primary victims of Nazi racism, but other victims included Roma (Gypsies) and people with mental or physical disabilities. The Nazis murdered some 200,000 Roma. And they murdered at least 250,000 mentally or physically disabled patients, mainly German and living in institutions, in the so-called Euthanasia Program.
Killing on a mass scale using gas chambers or gas vans was the main difference between the extermination and concentration camps.[269] From the end of 1941, the Germans built six extermination camps in occupied Poland: Auschwitz II-Birkenau, Majdanek, Chełmno, and the three Operation Reinhard camps at Belzec, Sobibor, and Treblinka II.[44][270] Maly Trostenets, a concentration camp in the Reichskommissariat Ostland, became a killing centre in 1942.[44] Gerlach writes that over three million Jews were murdered in 1942, the year that "marked the peak" of the mass murder of Jews.[271] At least 1.4 million of these were in the General Government area of Poland.[272]
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.
Innovators such as Heinz Guderian and Erich von Manstein recognised that the protection given by tanks increased the ability of the German army to manoeuvre in the face of enemy artillery, and that this enhanced speed and mobility. However, the modern technology was merely used to enhance the capabilities that had already been provided, thanks to the army's strategic doctrine.
Throughout the 1930s, the legal, economic, and social rights of Jews were steadily restricted.[83] On 1 April 1933, there was a boycott of Jewish businesses.[84] On 7 April 1933, the Law for the Restoration of the Professional Civil Service was passed, which excluded Jews and other "non-Aryans" from the civil service.[85] Jews were disbarred from practising law, being editors or proprietors of newspapers, joining the Journalists' Association, or owning farms.[86] In Silesia, in March 1933, a group of men entered the courthouse and beat up Jewish lawyers; Friedländer writes that, in Dresden, Jewish lawyers and judges were dragged out of courtrooms during trials.[87] Jewish students were restricted by quotas from attending schools and universities.[85] Jewish businesses were targeted for closure or "Aryanization", the forcible sale to Germans; of the approximately 50,000 Jewish-owned businesses in Germany in 1933, about 7,000 were still Jewish-owned in April 1939. Works by Jewish composers,[88] authors, and artists were excluded from publications, performances, and exhibitions.[89] Jewish doctors were dismissed or urged to resign. The Deutsches Ärzteblatt (a medical journal) reported on 6 April 1933: "Germans are to be treated by Germans only."[90]
On January 20, 1942, several top officials of the German government met to officially coordinate the military and civilian administrative branches of the Nazi system to organize a system of mass murder of the Jews. This meeting, called the Wannsee Conference, "marked the beinning of the full-scale, comprehensive extermination operation [of the Jews] and laid the foundations for its organization, which started immediately after the conference ended" (Yahil, The Holocaust, p. 318).
Schindler’s story remained largely the province of Holocaust scholars until the publication in 1982 of Schindler’s Ark, a Booker Prize-winning novelization by Thomas Keneally. The novel, which became a canonical text of Holocaust literature, was later used as the basis for Steven Spielberg’s film Schindler’s List (1993), which starred Liam Neeson as Schindler and Ralph Fiennes as Göth.

The most notorious physician was Josef Mengele, an SS officer who became the Auschwitz camp doctor on 30 May 1943.[54] Interested in genetics[54] and keen to experiment on twins, he would pick out subjects from the new arrivals during "selection" on the ramp, shouting "Zwillinge heraus!" (twins step forward!).[55] They would be measured, killed, and dissected. One of Mengele's assistants said in 1946 that he was told to send organs of interest to the directors of the "Anthropological Institute in Berlin-Dahlem". This is thought to refer to Mengele's academic supervisor, Otmar Freiherr von Verschuer , director from October 1942 of the Kaiser Wilhelm Institute of Anthropology, Human Heredity, and Eugenics in Berlin-Dahlem.[56][55][i] Mengele's experiments included placing subjects in pressure chambers, testing drugs on them, freezing them, attempting to change their eye color by injecting chemicals into children's eyes, and amputations and other surgeries.[59]

As the Red Army drew nearer in July 1944, the SS began closing down the easternmost concentration camps and evacuating the remaining prisoners westward to Auschwitz and Gross-Rosen concentration camp. Göth's personal secretary, Mietek Pemper, alerted Schindler to the Nazis' plans to close all factories not directly involved in the war effort, including Schindler's enamelware facility. Pemper suggested to Schindler that production should be switched from cookware to anti-tank grenades in an effort to save the lives of the Jewish workers. Using bribery and his powers of persuasion, Schindler convinced Göth and the officials in Berlin to allow him to move his factory and his workers to Brünnlitz (Czech: Brněnec), in the Sudetenland, thus sparing them from certain death in the gas chambers. Using names provided by Jewish Ghetto Police officer Marcel Goldberg, Pemper compiled and typed the list of 1,200 Jews—1,000 of Schindler's workers and 200 inmates from Julius Madritsch's textiles factory—who were sent to Brünnlitz in October 1944.[62][63][64][65]
