The Warsaw Ghetto Uprising was the largest ghetto revolt. Massive deportations (or Aktions) had been held in the ghetto from July to September 1942, emptying the ghetto of the majority of Jews imprisoned there. When the Germans entered the ghetto again in January 1943 to remove several thousand more, small unorganized groups of Jews attacked them. After four days, the Germans withdrew from the ghetto, having deported far fewer people than they had intended. The Nazis reentered the ghetto on April 19, 1943, the eve of Passover, to evacuate the remaining Jews and close the ghetto. The Jews, using homemade bombs and stolen or bartered weapons, resisted and withstood the Germans for 27 days. They fought from bunkers and sewers and evaded capture until the Germans burned the ghetto building by building. By May 16 the ghetto was in ruins and the uprising crushed.
Before World War II, Germany considered mass deportation from Europe of German, and later European, Jewry.[130] Among the areas considered for possible resettlement were British Palestine[131] and French Madagascar.[132] After the war began, German leaders considered deporting Europe's Jews to Siberia.[133][134] Palestine was the only location to which any German relocation plan produced results, via the Haavara Agreement between the Zionist Federation of Germany and the German government.[135] This resulted in the transfer of about 60,000 German Jews and $100 million from Germany to Palestine, but it ended with the outbreak of World War II.[136] In May 1940 Madagascar became the focus of new deportation efforts[132] because it had unfavorable living conditions that would hasten deaths.[137] Several German leaders had discussed the idea in 1938, and Adolf Eichmann's office was ordered to carry out resettlement planning, but no evidence of planning exists until after the fall of France in June 1940.[138] But the inability to defeat Britain prevented the movement of Jews across the seas,[139] and the end of the Madagascar Plan was announced on 10 February 1942.[140]
^ After the invasion of Poland, the Germans planned to set up a Jewish reservation in southeast Poland around the transit camp in Nisko, but the "Nisko Plan" failed, in part because it was opposed by Hans Frank, the new Governor-General of the General Government territory.[147][148][149] Adolf Eichmann was assigned to remove Jews from Germany, Austria, and the Protectorate of Bohemia and Moravia to the reservation.[150] Although the idea was to remove 80,000 Jews, Eichmann had managed to send only 4,700 by March 1940, and the plan was abandoned in April.[151] By mid-October the idea of a Jewish reservation had been revived by Heinrich Himmler, because of the influx of Germanic settlers into the Warthegau.[152] Resettlement continued until January 1941 under Odilo Globocnik,[153] and included both Jews and Poles.[154] By that time 95,000 Jews were already concentrated in the area,[155] but the plan to deport up to 600,000 additional Jews to the Lublin reservation failed for logistical and political reasons.[156]

The generally accepted definition of blitzkrieg operations include the use of maneuver rather than attrition to defeat an opponent, and describe operations using combined arms concentration of mobile assets at a focal point, armour closely supported by mobile infantry, artillery and close air support assets. These tactics required the development of specialized support vehicles, new methods of communication, new tactics, and an effective decentralized command structure. Broadly speaking, blitzkrieg operations required the development of mechanized infantry, self-propelled artillery and engineering assets that could maintain the rate of advance of the tanks. German forces avoided direct combat in favour of interrupting an enemy's communications, decision-making, logistics and of reducing morale. In combat, blitzkrieg left little choice for the slower defending forces but to clump into defensive pockets that were encircled and then destroyed by following German infantry.

Shipments of Jews to the camps had priority over anything but the army's needs on the German railways, and continued even in the face of the increasingly dire military situation at the end of 1942.[355] Army leaders and economic managers complained about this diversion of resources and the killing of skilled Jewish workers,[356] but Nazi leaders rated ideological imperatives above economic considerations.[357]
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.

Germany's last offensive on its Western front, Operation Wacht am Rhein, was an offensive launched towards the vital port of Antwerp in December 1944. Launched in poor weather against a thinly-held Allied sector, it achieved surprise and initial success as Allied air power was stymied by cloud cover. However, stubborn pockets of defence in key locations throughout the Ardennes, the lack of serviceable roads, and poor German logisitics planning caused delays. Allied forces deployed to the flanks of the German penetration, and Allied aircraft were again able to attack motorized columns. However, the stubborn defense of US units and German weakness led to a defeat for the Germans.
In Autumn 1943, the camp administration was reorganized following a corruption scandal. By the end of 1943, the prisoner population of Auschwitz main camp, Birkenau, Monowitz and other subcamps was over 80,000: 18,437 in the main camp, 49,114 in Birkenau, and 13,288 at Monowitz where I G Farben had its synthetic rubber plant. Up to 50,000 prisoners were scattered around 51 subcamps such as Rajsko, an experimental agricultural station, and Gleiwitz, a coal mine (see The List of the Camps for a complete list of those subcamps).
Hitler’s worldview revolved around two concepts: territorial expansion (that is, greater Lebensraum—“living space”—for the German people) and racial supremacy. After World War I the Allies denied Germany colonies in Africa, so Hitler sought to expand German territory and secure food and resources—scarce during World War I—in Europe itself. Hitler viewed the Jews as racial polluters, a cancer on German society in what has been termed by Holocaust survivor and historian Saul Friedländer “redemptive anti-Semitism,” focused on redeeming Germany from its ills and ridding it of a cancer on the body politic. Historian Timothy Snyder characterized the struggle as even more elemental, as “zoological,” and “ecological,” a struggle of the species. Hitler opposed Jews for the values they brought into the world. Social justice and compassionate assistance to the weak stood in the way of what he perceived as the natural order, in which the powerful exercise unrestrained power. In Hitler’s view, such restraint on the exercise of power would inevitably lead to the weakening, even the defeat, of the master race.
By the end of the war, Schindler had spent his entire fortune on bribes and black market purchases of supplies for his workers.[80] Virtually destitute, he moved briefly to Regensburg and later Munich, but did not prosper in postwar Germany. In fact, he was reduced to receiving assistance from Jewish organisations.[39] In 1948 he presented a claim for reimbursement of his wartime expenses to the American Jewish Joint Distribution Committee, and received $15,000.[81] He estimated his expenditures at over $1,056,000, including the costs of camp construction, bribes, and expenditures for black market goods, including food.[82] Schindler emigrated to Argentina in 1949, where he tried raising chickens and then nutria, a small animal raised for its fur. When the business went bankrupt in 1958, he left his wife and returned to Germany, where he had a series of unsuccessful business ventures, including a cement factory.[83][84] He declared bankruptcy in 1963 and suffered a heart attack the next year, which led to a month-long stay in hospital.[85] Remaining in contact with many of the Jews he had met during the war, including Stern and Pfefferberg, Schindler survived on donations sent by Schindlerjuden from all over the world.[84][86] He died on 9 October 1974 and is buried in Jerusalem on Mount Zion, the only member of the Nazi Party to be honoured in this way.[39][84] For his work during the war, on 8 May 1962, Yad Vashem invited Schindler to a ceremony during which a carob tree planted in his honor on the Avenue of the Righteous.[87] He and his wife, Emilie, were named Righteous Among the Nations, an award bestowed by the State of Israel on non-Jews who took an active role to rescue Jews during the Holocaust, on 24 June 1993.[88] Other awards include the German Order of Merit (1966).[89]

Below are figures for the number of Jews murdered in each country that came under German domination. They are estimates, as are all figures relating to Holocaust victims. The numbers given here for Czechoslovakia, Hungary and Romania are based on their territorial borders before the 1938 Munich agreement. The total number of six million Jews murdered during the Holocaust, which emerged from the Nuremberg trials, is also an estimate. Numbers have ranged between five and seven million killed.

I've been to Auschwitz Birkenau. On a cold November day I stood at the spot where the "selections" were made. Large snowflakes fell out the the gray somber sky, and skeletal poplars or other similar trees stood in the distance. I was chilled to the bone with a coldness that did not leave me until long after I reboarded the heated bus that took me back to Krakow. Every civilized person should go there and see how apparently civilized people conducted the most inhumane and uncivilized rituals in all of recorded history.
Also that November, Schindler was introduced to Itzhak Stern, an accountant for Schindler's fellow Abwehr agent Josef "Sepp" Aue, who had taken over Stern's formerly Jewish-owned place of employment as a Treuhander (trustee).[21] Property belonging to Polish Jews, including their possessions, places of business, and homes were seized by the Germans beginning immediately after the invasion, and Jewish citizens were stripped of their civil rights.[22] Schindler showed Stern the balance sheet of a company he was thinking of acquiring, an enamelware factory called Rekord Ltd[a] owned by a consortium of Jewish businessmen that had filed for bankruptcy earlier that year.[23] Stern advised him that rather than running the company as a trusteeship under the auspices of the Haupttreuhandstelle Ost (Main Trustee Office for the East), he should buy or lease the business, as that would give him more freedom from the dictates of the Nazis, including the freedom to hire more Jews.[24]
