Estimates of Jewish participation in partisan units throughout Europe range from 20,000 to 100,000.[323] In the occupied Polish and Soviet territories, thousands of Jews fled into the swamps or forests and joined the partisans,[324] although the partisan movements did not always welcome them.[325] An estimated 20,000 to 30,000 joined the Soviet partisan movement.[326] One of the famous Jewish groups was the Bielski partisans in Belarus, led by the Bielski brothers.[324] Jews also joined Polish forces, including the Home Army. According to Timothy Snyder, "more Jews fought in the Warsaw Uprising of August 1944 than in the Warsaw Ghetto Uprising of April 1943".[327][r]
British theorists J.F.C. Fuller and Captain B. H. Liddell Hart have often been associated with blitzkrieg's development, though this is a matter of controversy. The British War Office did permit an Experimental Mechanised Force, formed on 1 May 1927, that was wholly motorized including self propelled artillery and motorised engineers. It is argued that Guderian, a critical figure in blitzkrieg's conception, drew some of his inspiration from Liddell Hart. This was based on a paragraph in the English edition of Guderian's autobiography in which he credits Liddell Hart. In opposition, it is argued that Liddell Hart, as editor of the autobiography's English edition, wrote that paragraph himself or, more broadly, that his influence on Guderian was not as significant as held. Fuller's influence is less clear. During the war, he developed plans for massive, independent tank operations and was subsequently studied by the German leadership. It is variously argued that Fuller's wartime plans and post-war writings were an inspiration, or that his readership was low and German experiences during the war received more attention.

What is clear is the practical implementation of this doctrine in a wide and successful range of scenarios by Guderian and other Germans during the war. From early combined-arms river crossings and penetration exploitations during the advance in France in 1940 to massive sweeping advances in Russia in 1941, Guderian showed a mastery and innovation that inspired many others. This leadership was supported and fostered by the Reichswehr General Staff system, which worked the Army to greater and greater levels of capability through massive and systematic Movement Warfare war games in the 1930s.
Ultimately, three SS guards were killed—one of whom was burned alive by the prisoners in the oven of Crematorium II[230]—and 451 Sonderkommandos were killed.[232][233] Hundreds of prisoners escaped, but all were soon captured and executed, along with an additional group who had participated in the revolt.[230] Crematorium IV was destroyed in the fighting. A group of prisoners in the gas chamber of Crematorium V was spared in the chaos.[231][230]

Guderain recognised the importance of tanks  © This doctrine integrated the operational-level ideas taught by Schlieffen with the tactical concepts developed during World War One. And as military technology, including that of tanks, motor vehicles, aircraft and radios, was developed during the 1920s and 30s, so it was grafted onto this doctrinal framework.
From the first escape on 6 July 1940 of Tadeusz Wiejowski,[215] at least 802 prisoners (757 men and 45 women) tried to escape from the camp, according to Polish historian Henryk Świebocki. He writes that most escapes were attempted from work sites outside the camp.[216][f] Of these, 144 were successful and the fate of 331 is unknown.[217] Four Polish prisoners—Eugeniusz Bendera (a car mechanic at the camp), Kazimierz Piechowski, Stanisław Gustaw Jaster, and a priest, Józef Lempart—escaped successfully on 20 June 1942.[218] After breaking into a warehouse, the four dressed as members of the SS-Totenkopfverbände (the SS units responsible for concentration camps), armed themselves, and stole an SS staff car, which they drove unchallenged through the main gate, greeting several officers with "Heil Hitler!" as they drove past.[219] On 21 July 1944, Polish inmate Jerzy Bielecki dressed in an SS uniform and, using a faked pass, managed to cross the camp's gate with his Jewish girlfriend, Cyla Cybulska (known as Cyla Stawiska), pretending that she was wanted for questioning. Both survived the war. For having saved her, Bielecki was recognized by Yad Vashem as Righteous Among the Nations.[220]
The Holocaust (also called Ha-Shoah in Hebrew) refers to the period from January 30, 1933 - when Adolf Hitler became chancellor of Germany - to May 8, 1945, when the war in Europe officially ended. During this time, Jews in Europe were subjected to progressively harsher persecution that ultimately led to the murder of 6,000,000 Jews (1.5 million of these being children) and the destruction of 5,000 Jewish communities. These deaths represented two-thirds of European Jewry and one-third of all world Jewry.
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.
The Gestapo arrested him several times and interrogated him on charges of irregularities and of favoring Jews. However, Schindler would not desist. In 1943, at the invitation of the American Jewish Joint Distribution Committee, he undertook a highly risky journey to Budapest, where he met with two representatives of Hungarian Jewry. He reported to them about the desperate plight of the Jews in Poland and discussed possible ways of relief.
He went on to say that the use of tanks "left much to be desired...Fear of enemy action against the flanks of the advance, fear which was to prove so disastrous to German prospects in the west in 1940 and in the Soviet Union in 1941, was present from the beginning of the war." John Ellis further asserted that "...there is considerable justice in Matthew Cooper's assertion that the panzer divisions were not given the kind of strategic mission that was to characterize authentic armored blitzkrieg, and were almost always closely subordinated to the various mass infantry armies."
Overy wrote that blitzkrieg as a "coherent military and economic concept has proven a difficult strategy to defend in light of the evidence".[127] Milward's theory was contrary to Hitler's and German planners' intentions. The Germans, aware of the errors of the First World War, rejected the concept of organising its economy to fight only a short war. Therefore, focus was given to the development of armament in depth for a long war, instead of armament in breadth for a short war. Hitler claimed that relying on surprise alone was "criminal" and that "we have to prepare for a long war along with surprise attack". During the winter of 1939–40, Hitler demobilised many troops from the army to return as skilled workers to factories because the war would be decided by production, not a quick "Panzer operation".[128]
In his 1965 essay "Command and Compliance", which originated in his work as an expert witness for the prosecution at the Frankfurt Auschwitz Trials, the German historian Hans Buchheim wrote there was no coercion to murder Jews and others, and all who committed such actions did so out of free will. Buchheim wrote that chances to avoid executing criminal orders "were both more numerous and more real than those concerned are generally prepared to admit",[468] and that he found no evidence that SS men who refused to carry out criminal orders were sent to concentration camps or executed.[469] Moreover, SS rules prohibited acts of gratuitous sadism, as Himmler wished for his men to remain "decent"; acts of sadism were carried out on the initiative of those who were either especially cruel or wished to prove themselves ardent National Socialists.[468] Finally, he argued that those of a non-criminal bent who committed crimes did so because they wished to conform to the values of the group they had joined and were afraid of being branded "weak" by their colleagues if they refused.[470]
German military history had been influenced heavily by Carl von Clausewitz, Alfred von Schlieffen and von Moltke the Elder, who were proponents of maneuver, mass, and envelopment. Their concepts were employed in the successful Franco-Prussian War and attempted "knock-out blow" of the Schlieffen Plan. Following the war, these concepts were modified by the Reichswehr. Its Chief of Staff, Hans von Seeckt, moved doctrine away from what he argued was an excessive focus on encirclement towards one based on speed. Speed gives surprise, surprise allows exploitation if decisions can be reached quickly and mobility gives flexibility and speed. Von Seeckt advocated effecting breakthroughs against the enemy's centre when it was more profitable than encirclement or where encirclement was not practical. Under his command a modern update of the doctrinal system called "Bewegungskrieg" and its associated tactical system called " Auftragstaktik" was developed which resulted in the popularly known blitzkrieg effect. He additionally rejected the notion of mass which von Schlieffen and von Moltke had advocated. While reserves had comprised up to four-tenths of German forces in pre-war campaigns, von Seeckt sought the creation of a small, professional (volunteer) military backed by a defense-oriented militia. In modern warfare, he argued, such a force was more capable of offensive action, faster to ready, and less expensive to equip with more modern weapons. The Reichswehr was forced to adopt a small and professional army quite aside from any German plans, for the Treaty of Versailles limited it to 100,000 men.

The book’s existence as something of a quasi-novel/biography serves the needs of Young Adult Readers in two very important ways. First, it makes factual accounts accessible and exciting. Rather than dispassionately seek the stark facts of The Holocaust and those who resisted it, readers are able to pathetically experience the suffering and moral conflict. Thus the faculties of imagination and empiricism are both equally engaged. This can lead to more exciting and productive discussions. Second, the reliability of this kind of novel in representing fact portrays the ethical difficulties inherent in The Holocaust. We Goeth as the monstrous sadist and mass murderer, but also as the companion, connoisseur, and host. We see Schindler as the philanthropist, but also as the womanizer and profiteer. The net result is that a Young Adult is presented with an ethical reality in which there are absolutes being encountered by fallible people, people who are not absolute.

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]
Information about Auschwitz became available to the Allies as a result of reports by Captain Witold Pilecki of the Polish Home Army (Armia Krajowa), who volunteered to be imprisoned there in 1940. As "Thomasz Serfiński", he allowed himself to be arrested in Warsaw and spent 945 days in the camp, from 22 September 1940[199] until his escape on 27 April 1943. Michael Fleming writes that Pilecki was instructed to sustain morale, organize food, clothing and resistance, prepare to take over the camp if possible, and smuggle information out to the Polish military.[200] Pilecki called his resistance movement Związek Organizacji Wojskowej (ZOW, "Union of Military Organization").[199]

Płaszów concentration camp opened in March 1943 on the former site of two Jewish cemeteries on Jerozilimska Street, about 2.5 kilometres (1.6 mi) from the DEF factory.[49] In charge of the camp was SS-Hauptsturmführer Amon Göth, a sadist who would shoot inmates of the camp at random.[48] Inmates at Płaszów lived in constant fear for their lives.[50] Emilie Schindler called Göth "the most despicable man I have ever met."[51]
