Initially Göth's plan was that all the factories, including Schindler's, should be moved inside the camp gates.[52] However, Schindler, with a combination of diplomacy, flattery, and bribery, not only prevented his factory from being moved, but convinced Göth to allow him to build (at Schindler's own expense) a subcamp at Emalia to house his workers plus 450 Jews from other nearby factories. There they were safe from the threat of random execution, were well fed and housed, and were permitted to undertake religious observances.[53][54]
Some prisoners—usually Aryan—were assigned positions of authority, such as Blockschreiber ("block clerk"), Funktionshäftling ("functionary"), Kapo ("head" or "overseer"), and Stubendienst ("barracks orderly"). They were considered members of the camp elite, and had better food and lodgings than the other prisoners. The Kapos in particular wielded tremendous power over other prisoners, whom they often abused.[88][89] Very few Kapos were prosecuted after the war, because of the difficulty in determining which Kapo atrocities had been performed under SS orders and which had been individual actions.[90]

Birkenau was also home to two so-called family camps.  Inmates from the Czech ‘model ghetto’ Theresienstadt were deported in several transports to Birkenau, where they lived in the ‘family camp’, did not have their heads shaved, were better fed, and were freed from slave labour assignments.  They were also allowed far more freedom to create and continue the cultural production that had been the hallmark of life in Theresienstadt.  As was the case in Theresienstadt, however, this ‘generosity’ was solely for the sake of propaganda, only temporarily delaying the killing.  There was in the family camp a small musical group that was frequently required to play for the SS while they were drinking, as well as during public beatings.  Perhaps the cruellest freedom allowed the Czech camp was the freedom to educate their children.  Lessons were given in reading and counting. There were also singing and recorder lessons, with a focus on Jewish and Czech music.  In two major killing waves of March and July 1944, the Theresienstadt family camp was liquidated.
A parallel system operated later at Birkenau in 1942-43, except that for the majority the 'showers' proved to be gas chambers. Only about 10 percent of Jewish transports were registered, disinfected, shaven and showered in the 'central sauna' before being assigned barracks. In May 1944, a spur line was built right into the camp to accelerate and simplify the handling of the tens of thousands of Hungarian and other Jews deported in the spring and summer of 1944.
After those initial German successes, the Allies adopted this form of warfare with great success, beginning with Stalingrad and subsequently used by commanders such as U.S. Gen. George Patton in the European operations of 1944. The Germans’ last successful Kessel campaign was against the British paratroops at Arnhem, Netherlands, an encirclement that came to be known as the Hexenkessel (“witches’ cauldron”). By the end of the war, Germany found itself defeated by the strategic (Schwerpunkt) and tactical (Kesselschlacht) concepts that had initially brought it such success. German armies were destroyed at Falaise in France, the Scheldt in the Netherlands, and the Bulge in Belgium and on the Eastern Front at Cherkasy (in modern Ukraine), Memel (now Klaipėda, Lithuania), and Halbe, Germany. The last great battle of World War II fought using blitzkrieg tactics was the Battle of Berlin (April 1945).
The first gas chamber at Birkenau was in what prisoners called the "little red house" (known as bunker 1 by the SS), a brick cottage that had been converted into a gassing facility. The windows were bricked up and its four rooms converted into two insulated rooms, the doors of which said "Zur Desinfektion" ("to disinfection"). It was operational by March 1942. A second brick cottage, the "little white house" or bunker 2, was converted and operational by June 1942.[45] When Himmler visited the camp on 17 and 18 July 1942, he was given a demonstration of a selection of Dutch Jews, a mass killing in a gas chamber in bunker 2, and a tour of the building site of the new IG Farben plant being constructed at the nearby town of Monowitz.[46]
Under Laks' more positive leadership, the orchestra began to increase in size again.  His efforts won his musicians easier work assignments and a dispensation not to play outdoors in bad weather.  By the end of 1943, there were about forty members, including many Jews, from France, Germany, Poland, the Netherlands and Greece.  They included Henry Meyer, Louis Bannet, and Jacques Stroumsa.
At Auschwitz alone, more than 2 million people were murdered in a process resembling a large-scale industrial operation. A large population of Jewish and non-Jewish inmates worked in the labor camp there; though only Jews were gassed, thousands of others died of starvation or disease. During the summer of 1944, even as the events of D-Day (June 6, 1944) and a Soviet offensive the same month spelled the beginning of the end for Germany in the war, a large proportion of Hungary’s Jewish population was deported to Auschwitz, and as many as 12,000 Jews were killed every day.
Schindler founded the first foreign subsidiary in Berlin (Germany) in 1906. Thereafter, the company expanded continuously and mainly throughout Europe. The company established a branch in London in 1960, operating under the name Platt-Schindler and in France after acquiring Roux Combaluzier in 1969, which it was later known as Roux Combaluzier Schindler or RCS. In the 1970s, Schindler moves to its current headquarter in Ebikon, Switzerland.
Military historians have defined blitzkrieg as the employment of the concepts of maneuver and combined arms warfare developed in Germany during both the interwar period and the Second World War. Strategically, the ideal was to swiftly effect an adversary's collapse through a short campaign fought by a small, professional army. Operationally, its goal was to use indirect means, such as, mobility and shock, to render an adversary's plans irrelevant or impractical. To do this, self-propelled formations of tanks; motorized infantry, engineers, artillery; and ground-attack aircraft operated as a combined-arms team. Historians have termed it a period form of the longstanding German principle of Bewegungskrieg, or movement war.

Peter Hayes (How Was It Possible? A Holocaust Reader, 2015): "The Holocaust, the Nazi attempt to eradicate the Jews of Europe, has come to be regarded as the emblematic event of Twentieth Century ... Hitler's ideology depicted the Jews as uniquely dangerous to Germany and therefore uniquely destined to disappear completely from the Reich and all territories subordinate to it. The threat posted by supposedly corrupting but generally powerless Sinti and Roma was far less, and therefore addressed inconsistently in the Nazi realm. Gay men were defined as a problem only if they were German or having sex with Germans or having sex with Germans and considered 'curable' in most cases. ... Germany's murderous intent toward the handicapped inhabitants of European mental institutions ... was more comprehensive ... but here, too, implementation was uneven and life-saving exceptions permitted, especially in Western Europe. Not only were some Slavs—Slovaks, Croats, Bulgarians, some Ukrainians—allotted a favored place in Hitler's New Order, but the fate of most of the other Slavs the Nazis derided as sub-humans ... consisted of enslavement and gradual attrition, not the prompt massacre meted out to the Jews after 1941."[20]

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.
Who knew actor Ralph Fiennes would be so possessive of his Voldemort role from the Harry Potter movies? After all the hours sitting in a makeup chair, putting on a bald cap, and making his nose disappear day after day, you’d think Fiennes would be ok with never playing this evil character again—especially considering that he almost turned down the role in the first place. But it seems that the character really grew on the two-time Oscar nominee. As Screen Rant reports, Fiennes has made it clear that if Voldemort is ever needed in a future film, he's ready to come back.
Other historians wrote that blitzkrieg was an operational doctrine of the German armed forces and a strategic concept on which the leadership of the Third Reich based its strategic and economic planning. Military planners and bureaucrats in the war economy appear rarely, if ever, to have employed the term blitzkrieg in official documents. That the German army had a "blitzkrieg doctrine" was rejected in the late 1970s by Matthew Cooper. The concept of a blitzkrieg Luftwaffe was challenged by Richard Overy in the late 1970s and by Williamson Murray in the mid-1980s. That the Third Reich went to war on the basis of "blitzkrieg economics" was criticised by Richard Overy in the 1980s and George Raudzens described the contradictory senses in which historians have used the word. The notion of a German blitzkrieg concept or doctrine survives in popular history and many historians still support the thesis.[110]
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.
[Steinlauf says] ‘…even in this place one can survive, and therefore one must want to survive, to tell the story, to bear witness; and that to survive we must force ourselves to save at least the skeleton, the scaffolding, the form of civilisation. We are slaves, deprived of every right, exposed to every insult, condemned to certain death, but… … we must certainly wash our faces without soap in dirty water and dry ourselves on our jackets…. …for dignity… We must walk erect, without dragging our feet… …to remain alive, not to begin to die.’”
Although effective in quick campaigns against Poland and France, blitzkrieg could not be sustained by Germany in later years. Blitzkrieg strategy has the inherent danger of the attacking force overextending its supply lines, and the strategy as a whole can be defeated by a determined foe who is willing to sacrifice territory for time in which to regroup and rearm, as the Soviets did on the Eastern Front. Tank and vehicle production was a constant problem for Germany; indeed, late in the war many panzer "divisions" had no more than a few dozen tanks. As the end of the war approached, Germany also experienced critical shortages in fuel and ammunition stocks as a result of Anglo-American strategic bombing. Although production of Luftwaffe fighter aircraft continued, they would be unable to fly for lack of fuel. What fuel there was went to panzer divisions, and even then they were not able to operate normally. Of those Tiger tanks lost against the United States Army, nearly half of them were abandoned for lack of fuel.
The chief of construction of Auschwitz II-Birkenau was Karl Bischoff, a competent and dynamic bureaucrat who, in spite of the ongoing war, carried out the construction deemed necessary. The Birkenau camp, the four crematoria, a new reception building, and hundreds of other buildings were planned and constructed.[42] Bischoff's plans, based on an initial budget of RM 8.9 million, called for each barracks to hold 550 prisoners. He later changed this to 744 per barracks, which meant the camp could hold 125,000, rather than 97,000.[43] The SS designed the barracks not so much to house people as to destroy them.[42] There were 174 barracks, each measuring 116 by 36 ft, divided into 62 bays of 43 sq. ft. The bays were divided into "roosts", initially for three inmates and later for four. With personal space of 11 sq. ft to sleep and place whatever belongings they had, inmates were deprived, Robert-Jan van Pelt wrote, "of the minimum space needed to exist".[44]
The technique of Blitzkrieg is based on the principle of surprise as opposed to an effort to crush an enemy by bringing an overwhelming superiority in numbers and armament to bear against him. It can be likened to the swift and deadly thrust of a rapier as opposed to the crushing blow of a battle-axe or a war club. The objective is not the enemy civilian population but the enemy armed forces, both ground and air.
The first prisoners at Auschwitz included German prisoners transferred from Sachsenhausen concentration camp in Germany, where they had been incarcerated as repeat criminal offenders, and Polish political prisoners from Lodz via Dachau concentration camp and from Tarnow in Krakow District of the Generalgouvernement (that part of German-occupied Poland not annexed to Nazi Germany, linked administratively to German East Prussia, or incorporated into the German-occupied Soviet Union).

The majority—probably about 90%—of the victims of Auschwitz Concentration Camp died in Birkenau. This means approximately a million people. The majority, more than nine out of every ten, were Jews. A large proportion of the more than 70 thousand Poles who died or were killed in the Auschwitz complex perished in Birkenau. So did approximately 20 thousand Gypsies, in addition to Soviet POWs and prisoners of other nationalities. 

On 15 October 1944 a train carrying 700 men on Schindler's list was initially sent to the concentration camp at Gross-Rosen, where the men spent about a week before being re-routed to the factory in Brünnlitz.[66] Three hundred female Schindlerjuden were similarly sent to Auschwitz, where they were in imminent danger of being sent to the gas chambers. Schindler's usual connections and bribes failed to obtain their release. Finally after he sent his secretary, Hilde Albrecht, with bribes of black market goods, food and diamonds, the women were sent to Brünnlitz after several harrowing weeks in Auschwitz.[67]
