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.
Auschwitz-Birkenau is the generic name given to the cluster of concentration, labour and extermination camps established by the Nazis during the Second World War and located near the towns of Oświęcim and Brzezinka in southern Poland, some 60 km from Kraków. The camps have become a place of pilgrimage for survivors, their families and all who wish to travel to remember the Holocaust.
Despite the horrible conditions, prisoners in Auschwitz managed to resist the Nazis, including some instances of escape and armed resistance. In October 1944, members of the Sonderkommando, who worked in the crematoria, succeeded in killing several SS men and destroying one gas chamber. All of the rebels died, leaving behind diaries that provided authentic documentation of the atrocities committed at Auschwitz.
After the U.S. government refused to permit the passenger’s refuge, the St. Louis left Cuba for Europe. The St. Louis sailed so close to Florida that they could see the lights of Miami. The passengers were able to find refuge in other European countries so they didn’t have to return to Germany. Great Britain took 288, the Netherlands admitted 181; Belgium took 214, and 224 passengers found temporary refuge in France. When  Germany invaded Western Europe, 532 of the original passengers were trapped. Just over half survived the Holocaust.
On 31 July 1941, Hermann Göring gave written authorization to Reinhard Heydrich, Chief of the Reich Security Head Office (RSHA), to prepare and submit a plan for Die Endlösung der Judenfrage (the Final Solution of the Jewish question) in territories under German control and to coordinate the participation of all involved government organizations.[152] Plans for the extermination of the European Jews—eleven million people—were formalized at the Wannsee Conference in Berlin on 20 January 1942. Some would be worked to death and the rest killed.[153] Initially the victims were killed with gas vans or by Einsatzgruppen firing squads, but these methods were impractical for an operation of this scale.[154] By 1942, killing centers at Auschwitz, Sobibór, Treblinka, and other extermination camps had become the primary method of mass killing.[155]
During the era of the Holocaust, German authorities also targeted other groups because of their perceived racial and biological inferiority: Roma (Gypsies), people with disabilities, and some of the Slavic peoples (Poles, Russians, and others). Other groups were persecuted on political, ideological, and behavioral grounds, among them Communists, Socialists, Jehovah's Witnesses, and homosexuals.
Birkenau was the largest camp in the Auschwitz complex. It became primarily a centre for the mass murder of Jews brought there for extermination, and of Roma and Sinti prisoners during its final period. Sick prisoners and those selected for death from the whole Auschwitz complex – and, to a smaller extent, from other camps – were also gathered and systematically killed here. It ultimately became a place for the concentration of prisoners before they were transferred inside the Third Reich to work for German industry. Most of the victims of the Auschwitz complex, probably about 90%, were killed in the Birkenau camp.
In 1942, fifteen Nazi leaders met at a conference in Wannsee, Germany to discuss the “Jewish Question”. Their job was to decide the most efficient way to exterminate the Jews. They decided that Jews would be sent to extermination camps where they would be sent to showers. But instead of water coming out of the faucet, they faced their death when poisonous Zyklon-B gas leaked through the showerheads to suffocate them. This decision at the conference is called the “Final Solution.”

While concentration camps were meant to work and starve prisoners to death, extermination camps (also known as death camps) were built for the sole purpose of killing large groups of people quickly and efficiently. The Nazis built six extermination camps, all in Poland: Chelmno, Belzec, Sobibor, Treblinka, Auschwitz, and Majdanek. (Auschwitz and Majdanek were both concentration and extermination camps.)

Auschwitz, perhaps the most notorious and lethal of the concentration camps, was actually three camps in one: a prison camp (Auschwitz I), an extermination camp (Auschwitz II–Birkenau), and a slave labour camp (Auschwitz III–Buna-Monowitz). Upon arrival, Jewish prisoners faced what was called a Selektion. A German doctor presided over the selection of pregnant women, young children, the elderly, handicapped, sick, and infirm for immediate death in the gas chambers. As necessary, the Germans selected able-bodied prisoners for forced labour in the factories adjacent to Auschwitz, where one German company, IG Farben, invested 700 million Reichsmarks in 1942 alone to take advantage of forced labour, a capital investment. The conglomerate presumed that slave labour would be a permanent part of the German economy. Deprived of adequate food, shelter, clothing, and medical care, these prisoners were literally worked to death. Periodically, they would face another Selektion. The Nazis would transfer those unable to work to the gas chambers of Birkenau.
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.

Auschwitz became one of the camps used for the mass extermination of Jews. In summer 1941, Heinrich Himmler gave orders to Auschwitz commander Rudolf Höß to build a centre at Auschwitz for the mass murder of Jews. In September 1941, the lethal effects of Zyklon B - a substance normally used for pest control - were first tested and verified there. Later, four large gas chambers were built at Birkenau, capable of killing up to six thousand people each day. The gas chambers were disguised as showers, meant to persuade the victims that these were disinfection measures which they had to undergo before they were sent to work in the camp.
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]
Up to this point, Auschwitz accounted for only 11 percent of the victims of the 'Final Solution'. However, in August 1942, planning began for the construction of four large-scale gassing facilities. It appears from the plans that the first two gas chambers were adapted from mortuaries which, with the huge crematoria attached to them, were initially intended to cope with mortalities amongst the slave labor force in the camp, now approaching 100,000 and subject to a horrifying death rate. But from the autumn of 1942, it seems clear that the SS planners and civilian contractors were intending to build a mass-murder plant.
The SchindlerMobile is a self-propelled car has wheels to move itself up and down self-supporting aluminum columns. It doesn't have a machine room, no suspension ropes, and no hoistway walls. It was introduced in 1997, but later discontinued and replaced with the Schindler EuroLift elevators in 2001. SchindlerMobile was produced in its factory in Schlatt, Switzerland.
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]
Heinz Guderian is widely regarded as being highly influential in developing the military methods of warfare used by Germany's tank men at the start of the Second World War. This style of warfare brought manoeuvre back to the fore, and placed an emphasis on the offensive. This style, along with the shockingly rapid collapse in the armies that opposed it, came to be branded as blitzkrieg warfare.[15]

The direct reason for the establishment of the camp was the fact that mass arrests of Poles were increasing beyond the capacity of existing "local" prisons. The first transport of Poles reached KL Auschwitz from Tarnów prison on June 14, 1940. Initially, Auschwitz was to be one more concentration camp of the type that the Nazis had been setting up since the early 1930s. It functioned in this role throughout its existence, even when, beginning in 1942, it also became the largest of the death camps.
The Germans turned again, fighting their way north to secure the coastal ports and annihilate the trapped armies. Miraculously, the German high command called a halt to the advance. The reprieve lasted 48 hours, long enough for the British to defend Dunkirk and evacuate what they could of the Allied armies. The Germans entered Paris on June 14. In a humiliating ceremony on June 22, France signed an armistice with Germany, leaving Britain to carry on the fight alone.
^ Now came the riposte - a counter-attack [...] from the forest of Villers-Cotterets [...]. The French had developed a light and fast-moving tank. Two generals, Debeney on the British right, and Mangin, to his right, began the tactics that were to become famous in 1940 as Blitzkrieg - tanks, fast-moving infantry, and aircraft flying low to keep the German gunners' heads down. Three hundred tanks (Renault) and eighteen divisions, two of them American, struck in open cornfield, entirely by surprise, and went five miles forward. With the whole of the German force in the Marne salient threatened by a cut-off, Ludendorff pulled back from it, back to Chemin des Dames. By 4 August the French had taken 30,000 prisoners and 600 guns.[46]
In the German parliament, the Nazi party, led by Adolf Hitler, gained popularity. The number of seats Nazis controlled in the parliament rose from 12 in 1928 to 230 in 1932, making them the largest political party. The strong showing guaranteed the Nazi party would need to be part of any political coalition. Believing he could check Hitler’s ambition, President Hindenburg reluctantly made Hitler the Chancellor of Germany on January 30, 1933.

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."
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.
The next blow came a month later. In the early morning darkness of May 10, the Germans unleashed their Blitzkrieg against the Netherlands and Belgium. The attack sent the defending troops reeling. The roads overflowed with refugees fleeing the front. French and British troops rushing to the rescue were caught in the headlong retreat and pushed back. German dive-bombers - the Stukas - filled the sky, strafing the retreating mix of civilians and soldiers with machine gun and bomb. The Allies fought valiantly but in vain - the German war machine advanced unperturbed. In England, the invasion forced Prime Minister Neville Chamberlain to resign, to be replaced by Winston Churchill.

Once Germany took over Poland in 1939, it created forced-labor camps. Thousands of prisoners died from working conditions, exhaustion, and starvation. After the outbreak of World War II, the number of concentration camps increased exponentially. The number of prisoners of war camps also rose, but after the first years of the war most were converted into concentration camps. Nazis forcibly relocated Jews from ghettos to concentration camps.
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]
