Part of Spielberg’s reluctance to make Schindler's List was that he didn’t feel that he was prepared or mature enough to tackle a film about the Holocaust. So he tried to recruit other directors to make the film. He first approached director Roman Polanski, a Holocaust survivor whose own mother was killed in Auschwitz. Polanski declined, but would go on to make his own film about the Holocaust, The Pianist, which earned him a Best Director Oscar in 2003. Spielberg then offered the movie to director Sydney Pollack, who also passed.
In July 1943 the Wehrmacht conducted Operation Zitadelle (Citadel) against a salient at Kursk that was heavily defended by Soviet troops.[97][98] Soviet defensive tactics were by now hugely improved, particularly in the use of artillery and air support.[98][99] By April 1943, the Stavka had learned of German intentions through intelligence supplied by front line reconnaissance and Ultra intercepts.[100] In the following months, the Red Army constructed deep defensive belts along the paths of the planned German attack.[101] The Soviets made a concerted effort to disguise their knowledge of German plans and the extent of their own defensive preparations, and the German commanders still hoped to achieve operational surprise when the attack commenced.[102]

The camp was continually expanded over the next five years and ultimately consisted of three main parts: Auschwitz I, Auschwitz II-Birkenau, and Auschwitz III-Monowitz. Auschwitz-Birkenau also had over 40 sub-camps in the neighboring cities and in the surrounding area. Initially, only Poles and Jews were imprisoned, enslaved and murdered in the camp. Subsequently, Soviet prisoners of war (POWs), Romani/Sinti (Gypsies), and prisoners of other nationalities and minorities were also incarcerated, enslaved and murdered there.
With the deportations from Hungary, the role of Auschwitz-Birkenau in the German plan to murder the Jews of Europe achieved its highest effectiveness. Between late April and early July 1944, approximately 440,000 Jews were deported from Hungary. Of the nearly 426,000 Hungarian Jews deported to Auschwitz, approximately 320,000 of them were sent directly to the gas chambers in Auschwitz-Birkenau. They deployed approximately 110,000 at forced labor in the Auschwitz camp complex. The SS authorities transferred many of these Hungarian Jewish forced laborers within weeks of their arrival in Auschwitz to other concentration camps in Germany and Austria.
In 1933, Jews in Germany numbered around 525,000, or only 1 percent of the total German population. During the next six years, Nazis undertook an “Aryanization” of Germany, dismissing non-Aryans from civil service, liquidating Jewish-owned businesses and stripping Jewish lawyers and doctors of their clients. Under the Nuremberg Laws of 1935, anyone with three or four Jewish grandparents was considered a Jew, while those with two Jewish grandparents were designated Mischlinge (half-breeds).
Eight hundred to a thousand people were crammed into the superimposed compartments of each barracks. Unable to stretch out completely, they slept there both lengthwise and crosswise, with one man's feet on another's head, neck, or chest. Stripped of all human dignity, they pushed and shoved and bit and kicked each other in an effort to get a few more inches' space on which to sleep a little more comfortably. For they did not have long to sleep.[122]
Medical experiments conducted on camp inmates by the SS were another distinctive feature.[51] At least 7,000 prisoners were subjected to experiments; most died as a result, during the experiments or later.[52] Twenty-three senior physicians and other medical personnel were charged at Nuremberg, after the war, with crimes against humanity. They included the head of the German Red Cross, tenured professors, clinic directors, and biomedical researchers.[53] Experiments took place at Auschwitz, Buchenwald, Dachau, Natzweiler-Struthof, Neuengamme, Ravensbrück, Sachsenhausen, and elsewhere. Some dealt with sterilization of men and women, the treatment of war wounds, ways to counteract chemical weapons, research into new vaccines and drugs, and the survival of harsh conditions.[52]
In Birkenau, which was built anew on the site of a displaced village, only a small number of historic buildings have survived. Due to the method used in constructing those buildings, planned as temporary structures and erected in a hurry using demolition materials, the natural degradation processes have been accelerating. All efforts are nevertheless being taken to preserve them, strengthen their original fabric and protect them from decay.
Following the camp's liberation, the Soviet government issued a statement, on 8 May 1945, that four million people had been killed on the site, a figure based on the capacity of the crematoria and later regarded as too high.[184] Höss told prosecutors at Nuremberg that at least 2,500,000 people had been murdered in Auschwitz by gassing and burning, and that another 500,000 had died of starvation and disease.[185] He testified that the figure of over two million had come from Eichmann.[186][d] In his memoirs, written in custody, he wrote that he regarded this figure as "far too high. Even Auschwitz had limits to its destructive possibilities."[188] Raul Hilberg's 1961 work, The Destruction of the European Jews, estimated that up to 1,000,000 Jews had died in Auschwitz.[189]

Germany had suffered tremendously fighting a positional war during World War I, which prompted the Wehrmacht commanders and strategists to find ways to avoid becoming entrenched in such battles in the first place. Blitzkrieg was their solution — a method to smash through enemy lines in a positional confrontation before their opponents even realized what was happening. Using this maneuver Nazi Germany conquered Poland in a month, then subdued France in less than two months, despite France having the larger army and the best tanks in the world at that time.

Whilst carrying out this final evacuation the SS had set about removing evidence of their crimes. Many thousands of documents were set alight. Between 21 and 26 January 1945, the Germans blew up  and partially dismantled the gas chambers and crematoria in Birkenau. Kanada II, the warehouse in which property plundered from victims of the gas chambers was stored and sorted, was also looted and set alight. Members of the Wehrmacht joined in the looting.

To the Nazi regime, there would have been no doubt that a war against Bolshevism was implicitly a war against the Jewish population of the Soviet Union. A division of Hitler’s SS known as the Einsatzgruppen traveled behind the German army and acted as death squads, exterminating civilian populations in the most efficient way possible. During the early part of Operation Barbarossa these were frequently people who had fled the Nazi’s earlier invasion of Poland.
Blitzkrieg's unique and completely flexible campaign structure puts you in control of deciding how your forces will fare in each of the major engagements that comprise three central Campaigns. Hardcore vets have the option of engaging the enemy immediately in a desperate struggle for battlefield dominance, or more cautious players can choose from pre-defined or unlimited randomly generated side missions as they gain experience, promotions and weapons upgrades as well as wear down the enemy before the central conflict.

After the SS re-designated Plaszow as a concentration camp in August 1943, Schindler persuaded the SS to convert Emalia into a subcamp of Plaszow. In addition to the approximately 1,000 Jewish forced laborers registered as factory workers, Schindler permitted 450 Jews working in other nearby factories to live at Emalia as well. This saved them from the systematic brutality and arbitrary murder that was part of daily life in Plaszow.

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.
In reality, the way in which the Wehrmacht fought, their 'doctrine' in today's parlance, was based more upon ideas than technology. And the ideas that shaped how Hitler's army fought were influenced by the fighting methods German soldiers had used since the 1870s. The so-called blitzkrieg of 1940 was really the German doctrine of 1914 with technology bolted on.

In October 1941, work began on Auschwitz II, or Birkenau, located outside the nearby village of Brzezinka. There the SS later developed a huge concentration camp and extermination complex that included some 300 prison barracks; four large so-called Badeanstalten (German: “bathhouses”), in which prisoners were gassed to death; Leichenkeller (“corpse cellars”), in which their bodies were stored; and Einäscherungsöfen (“cremating ovens”). Another camp (Buna-Monowitz), near the village of Dwory, later called Auschwitz III, became in May 1942 a slave-labour camp supplying workers for the nearby chemical and synthetic-rubber works of IG Farben. In addition, Auschwitz became the nexus of a complex of 45 smaller subcamps in the region, most of which housed slave labourers. During most of the period from 1940 to 1945, the commandant of the central Auschwitz camps was SS-Hauptsturmführer (Capt.) and ultimately SS-Obersturmbannführer (Lieut. Col.) Rudolf Franz Hoess (Höss).
The SS: The SS was a military-style group of Nazis, founded in 1925, who were like Hitler's personal bodyguards. They were in charge of overseeing the killing of people in the camps. Part of the SS called the Einsatzgruppen were put in charge of killing many people, before the extermination camps were opened to carry this out on a much greater scale. The SS also took control of intelligence, security and the police force.
Memory is not something that is acquired once and stays on forever. The moment that the last eyewitnesses and survivors pass away, we have to work together to build on that which remains: the testimonies of those former prisoners and the authentic artifacts connected with Auschwitz. Each item can have its own enormous meaning and should find its place in the collection of the Auschwitz Memorial. Here, it will be preserved, studied, and displayed. Its place is here. 
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 early 1950s literature transformed blitzkrieg into a historical military doctrine, which carried the signature of Liddell Hart and Guderian. The main evidence of Liddell Hart's deceit and "tendentious" report of history can be found in his letters to Erich von Manstein, Heinz Guderian and the relatives and associates of Erwin Rommel. Liddell Hart, in letters to Guderian, "imposed his own fabricated version of blitzkrieg on the latter and compelled him to proclaim it as original formula".[145][146] Kenneth Macksey found Liddell Hart's original letters to Guderian in the General's papers, requesting that Guderian give him credit for "impressing him" with his ideas of armoured warfare. When Liddell Hart was questioned about this in 1968 and the discrepancy between the English and German editions of Guderian's memoirs, "he gave a conveniently unhelpful though strictly truthful reply. ('There is nothing about the matter in my file of correspondence with Guderian himself except...that I thanked him...for what he said in that additional paragraph'.)".[147]
Although she struggled with resentment towards her late husband for his womanizing and marital neglect, Emilie still had profound love for Schindler. Revealing her internal dialogue when she visited his tomb almost 40 years after his passing, she had said to him: "At last we meet again . . .I have received no answer, my dear, I do not know why you abandoned me . . . But what not even your death or my old age can change is that we are still married, this is how we are before God. I have forgiven you everything, everything. . ."
Auschwitz was considered a comfortable posting by many SS members, because of its many amenities.[84] SS personnel were initially allowed to bring partners, spouses, and children to live at the camp, but when the SS camp grew more crowded, Höss restricted further arrivals. Facilities for the SS personnel and their families included a library, swimming pool, coffee house, and a theater that hosted regular performances.[80]
In 1914, German strategic thinking derived from the writings of Carl von Clausewitz (June 1, 1780 – November 16, 1831), Helmuth von Moltke the Elder (26 October 1800 – 24 April 1891) and Alfred von Schlieffen (28 February 1833 – 4 January 1913), who advocated manoeuvre, mass and envelopment to create the conditions for a decisive battle (Vernichtungsschlacht). During the war, officers such as Willy Rohr developed tactics to restore manoeuvre on the battlefield. Specialist light infantry (Sturmtruppen, "storm troops") were to exploit weak spots to make gaps for larger infantry units to advance with heavier weapons and exploit the success, leaving isolated strong points to troops following up. Infiltration tactics were combined with short hurricane artillery bombardments using massed artillery, devised by Colonel Georg Bruchmüller. Attacks relied on speed and surprise rather than on weight of numbers. These tactics met with great success in Operation Michael, the spring offensive of 1918 and restored temporarily the war of movement, once the Allied trench system had been overrun. The German armies pushed on towards Amiens and then Paris, coming within 120 kilometres (75 mi) before supply deficiencies and Allied reinforcements halted the advance.[27] Historian James Corum criticised the German leadership for failing to understand the technical advances of the First World War, having given tank production the lowest priority and having conducted no studies of the machine gun prior to that war.[28]
Nevertheless, despite the lack of access to clean water, soap and a change of clothes, many prisoners continued to go through the motions of washing each morning. This was because, even though it was not possible to carry out the activities of a normal life, it was extremely important to preserve the ‘spirit’ of life, not to give up. This can be seen so vividly in the writings of Primo Levi, a survivor of Auschwitz, who went on to become a distinguished writer,

At Auschwitz I, the majority of the complex has remained intact. The architecture of the camp consisted mostly of pre-existing buildings converted by the Nazis to serve new functions. The preserved architecture, spaces and layout still recall the historical functions of the individual elements in their entirety. The interiors of some of the buildings have been modified to adapt them to commemorative purposes, but the external façades of these buildings remain unchanged.
Central to this is the decision cycle. Every decision made by German or opposing forces required time to gather information, make a decision, disseminate orders to subordinates, and then implement this decision through action. Through superior mobility and faster decision-making cycles, mobile forces could take action on a situation sooner than the forces opposing them.
Recognising that battlefield conditions changed rapidly and that orders often became overtaken by events, the German army encouraged its commanders to make decisions without waiting for orders from above, thus allowing them to take advantage of fleeting opportunities as they arose. Above all else, this doctrine created aggressive and flexible leaders.

Though classified as an armaments factory, the Brünnlitz plant produced just one wagonload of live ammunition in just under eight months of operation. By presenting bogus production figures, Schindler justified the existence of the subcamp as an armaments factory. This facilitated the survival of over 1,000 Jews, sparing them the horrors and brutality of conventional camp life. Schindler left Brünnlitz only on May 9, 1945, the day that Soviet troops liberated the camp.
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]
