The fortified walls, barbed wire, platforms, barracks, gallows, gas chambers and cremation ovens show the conditions within which the Nazi genocide took place in the former concentration and extermination camp of Auschwitz-Birkenau, the largest in the Third Reich. According to historical investigations, 1.5 million people, among them a great number of Jews, were systematically starved, tortured and murdered in this camp, the symbol of humanity's cruelty to its fellow human beings in the 20th century.

The Holocaust was the murder by Nazi Germany of six million Jews. While the Nazi persecution of the Jews began in 1933, the mass murder was committed during World War II. It took the Germans and their accomplices four and a half years to murder six million Jews. They were at their most efficient from April to November 1942 – 250 days in which they murdered some two and a half million Jews. They never showed any restraint, they slowed down only when they began to run out of Jews to kill, and they only stopped when the Allies defeated them. More...
From 1942, members of the Bureau of Information and Propaganda of the Warsaw-area Home Army published reports based on the accounts of escapees. The first was a fictional memoir, "Oświęcim. Pamiętnik więźnia" ("Auschwitz: Diary of a prisoner") by Halina Krahelska, published in April 1942 in Warsaw.[205] Also published in 1942 was the pamphlet Obóz śmierci (Camp of Death) by Natalia Zarembina,[206] and W piekle (In Hell) by Zofia Kossak-Szczucka, founder of Żegota.[207] In March 1944, the Polish Labor Group in New York published a report in English, "Oswiecim, Camp of Death (Underground Report)", with a foreword by Florence Jaffray Harriman, which described the gassing of prisoners from 1942.[208]

Throughout the late-1930s, the Nazi government began to forcibly acquire ethnically German territory in Austria and Czechoslovakia that was taken from Germany at the end of the First World War. Although the international community initially allowed Germany to incorporate these territories into the growing German Empire, it became increasingly clear that Hitler’s ambition did not stop at these small territories. When Germany invaded Poland on September 1, 1939, Britain and France responded by declaring war on Germany, beginning the Second World War.
In October 1944, the 'Sonderkommando' crew crematoria IV revolted and destroyed the crematories. In November Himmler ordered gassings to stop, and a 'cleanup' operation was inaugurated to conceal traces of the mass murder. In January 1945, the Germans evacuated 58,000 prisoners who could walk. They left behind in the main camp, Birkenau and in Monowitz about 7,000 sick or incapacitated who they did not expect would live for long.
The photo above shows the gate house which is the main entrance into Birkenau, also known as the Auschwitz II concentration camp. Beginning around the middle of May 1944, freight trains that were 40 to 50 cars long rolled through this gate, day and night, bringing thousands of Hungarian Jews to be gassed at the four Birkenau gas chambers. The prisoners called it the "Gate of Death."
Allied air superiority became a significant hindrance to German operations during the later years of the war. Early German successes enjoyed air superiority with unencumbered movement of ground forces, close air support, and aerial reconnaissance. However, the Western Allies' air-to-ground aircraft were so greatly feared out of proportion to their actual tactical success, that following the lead up to Operation Overlord German vehicle crews showed reluctance to move en masse during daylight. Indeed, the final German blitzkrieg operation in the west, Operation Wacht am Rhein, was planned to take place during poor weather which grounded Allied aircraft. Under these conditions, it was difficult for German commanders to employ the "armoured idea" to its envisioned potential.
The concept of blitzkrieg was formed by Prussian military tactics of the early 19th century, which recognized that victory could come only through forceful and swift action because of Prussia’s relatively limited economic resources. It had its origins with the Schwerpunktprinzip (“concentration principle”) proposed by Carl von Clausewitz in his seminal work On War (1832). Having studied generals who predated Napoleon, Clausewitz found that commanders of various armies had dispersed their forces without focused reasoning, which resulted in those forces’ being used inefficiently. So as to eliminate that wasteful use of manpower, he advocated for a concentration of force against an enemy. All employment of force should have an effective concentration in a single moment, with a single action, Clausewitz argued. Clausewitz called that concentration the Schwerpunkt (“centre of gravity”) where it was most dense, identifying it as the effective target for attack.
The women's concentration camp (Frauenkonzentrationslager or FKL) was established in August 1942, in 15 brick and 15 wooden barracks in sector BIa (Bauabschnitt Ia) in Auschwitz II, when 13,000 women were transferred from Auschwitz I. The camp was later extended into sector BIb, and by October 1943 it held 32,066 women. Conditions in the camp were so poor that, in October 1942, when a group of male prisoners arrived to set up an infirmary, their first task, according to researchers from the Auschwitz museum, was to distinguish the corpses from the women who were still alive.[123] Gisella Perl, a Romanian-Jewish gynecologist and inmate of the women's camp, wrote in 1948:
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 economic strains of the Great Depression led some in the German medical establishment to advocate murder (euphemistically called "euthanasia") of the "incurable" mentally and physically disabled as a cost-saving measure to free up funds for the curable.[66] By the time the National Socialist German Workers' Party, or Nazi Party,[j] came to power in 1933, there was already a tendency to seek to save the racially "valuable", while ridding society of the racially "undesirable".[68] The party had originated in 1920[67] as an offshoot of the völkisch movement, and it adopted that movement's antisemitism.[69] Early antisemites in the party included Dietrich Eckart, publisher of the Völkischer Beobachter, the party's newspaper, and Alfred Rosenberg, who wrote antisemitic articles for it in the 1920s. Rosenberg's vision of a secretive Jewish conspiracy ruling the world would influence Hitler's views of Jews by making them the driving force behind communism.[70] The origin and first expression of Hitler's antisemitism remain a matter of debate.[71] Central to his world view was the idea of expansion and lebensraum (living space) for Germany. Open about his hatred of Jews, he subscribed to the common antisemitic stereotypes.[72] From the early 1920s onwards, he compared the Jews to germs and said they should be dealt with in the same way. He viewed Marxism as a Jewish doctrine, said he was fighting against "Jewish Marxism", and believed that Jews had created communism as part of a conspiracy to destroy Germany.[73]

Blitzkrieg means “lightning war”. It was an innovative military technique first used by the Germans in World War Two and was a tactic based on speed and surprise. Blitzkrieg relied on a military force be based around light tank units supported by planes and infantry (foot soldiers). The tactic was based on Alfred von Schlieffen’s ‘Schlieffen Plan’ – this was a doctrine formed during WWI that focused on quick miliatry victory. It was later developed in Germany by an army officer called Heinz Guderian who looked at new technologies, namely dive bombers and light tanks, to improve the German army’s manoeuvrability.
By the end of September, the SS had started to develop plans to deport Jews to newly invaded Poland: the first steps towards the systematic murder that would follow. In Poland itself, thousands of Poles and Jews were rounded up and shot, early indications of the systematic murder that would follow. Alongside this, Hitler approved a new programme of euthanasia to exterminate the handicapped and mentally ill.
New arrivals to the Auschwitz camp complex were immediately sorted into two groups, those on the left and those on the right.  The few in the right-hand group would be sent to one of the various camps within Auschwitz to become forced labourers.  The remaining majority were sent to Birkenau, otherwise known as Auschwitz II, where they were gassed and cremated.  Birkenau, the death camp of Auschwitz, was also one of the few places where, historians confirm, music regularly accompanied selections and mass murder.  Former inmate Erika Rothschild remembered this macabre accompaniment:

In early 1942, mass exterminations were moved to two provisional gas chambers (the "red house" and "white house", known as bunkers 1 and 2) in Auschwitz II, while the larger crematoria (II, III, IV, and V) were under construction. Bunker 2 was temporarily reactivated from May to November 1944, when large numbers of Hungarian Jews were gassed.[161] In summer 1944 the combined capacity of the crematoria and outdoor incineration pits was 20,000 bodies per day.[162] A planned sixth facility—crematorium VI—was never built.[163] Prisoners were transported from all over German-occupied Europe by rail, arriving in daily convoys.[164] By July 1942, the SS were conducting "selections". Incoming Jews were segregated; those deemed able to work were sent to the selection officer's right and admitted into the camp, and those deemed unfit for labor were sent to the left and immediately gassed.[165] The group selected to die, about three-quarters of the total,[c] included almost all children, women with small children, the elderly, and all those who appeared on brief and superficial inspection by an SS doctor not to be fit for work.[167]
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]
