The enormous might of Hitler’s Wehrmacht in 1941 lay in the quality of its personnel, its optimized organizational decisions (regarding operations in tank groups, air fleets and other formations), its top-notch operational art and tactics and in the fact that many of its weapons systems and military technologies were well matched to the blitzkrieg’s objectives.
In general, subcamps that produced or processed agricultural goods were administratively subordinate to Auschwitz-Birkenau. Subcamps whose prisoners were deployed at industrial and armaments production or in extractive industries (e.g., coal mining, quarry work) were administratively subordinate to Auschwitz-Monowitz. This division of administrative responsibility was formalized after November 1943.
This aggressive technique is best used nowadays by visionary companies that accept the task to reshape certain industries. Being first confers the advantages of superior size that comes with being ahead of rivals and allows the business to set industry standards, influence customer preferences, develop a superior cost position, and determine the direction for an entire market.
As was the case in other camps, the primary form of voluntary music-making in Birkenau was singing.  Due to its size and international composition, there were inmates from all over Europe whose voices survivors remembered.  Prisoners sang to comfort one another, to build solidarity and to express resistance.  The former inmate Kitty Hart remembered that

On April 16, 1945 Soviets surrounded Berlin, Germany’s capital. When the Soviets began advancing towards the Reich Chancellery, Hitler committed suicide on April 30, 1945. Then on May 7th, Germany surrendered to the Western Allies in Reims, France and a few days later to the Soviets in Berlin. All told more than 60 million people, or about 3% of the world’s population at the time, were killed during the course of the Second World War.
On 15 September 1935, the Reichstag passed the Nuremberg Laws, prohibiting marriages between Jews and people of Germanic extraction, extramarital relations between Jews and Germans, and the employment of German women under the age of 45 as domestic servants in Jewish households.[12] The Reich Citizenship Law defined as citizens those of "German or kindred blood". Thus Jews and other minorities were stripped of their citizenship.[13] By the start of World War II in 1939, around 250,000 of Germany's 437,000 Jews had emigrated to the United States, Palestine, the United Kingdom, and other countries.[14][15]
Guderian argued that the tank would be the decisive weapon of the next war. "If the tanks succeed, then victory follows", he wrote. In an article addressed to critics of tank warfare, he wrote "until our critics can produce some new and better method of making a successful land attack other than self-massacre, we shall continue to maintain our beliefs that tanks—properly employed, needless to say—are today the best means available for land attack." Addressing the faster rate at which defenders could reinforce an area than attackers could penetrate it during the First World War, Guderian wrote that "since reserve forces will now be motorized, the building up of new defensive fronts is easier than it used to be; the chances of an offensive based on the timetable of artillery and infantry co-operation are, as a result, even slighter today than they were in the last war." He continued, "We believe that by attacking with tanks we can achieve a higher rate of movement than has been hitherto obtainable, and—what is perhaps even more important—that we can keep moving once a breakthrough has been made."[154][l] Guderian additionally required that tactical radios be widely used to facilitate coordination and command by having one installed in all tanks.
When the selection process was complete, a work group of prisoners called the ‘Kanada Kommando’ collected the belongings of victims and took them to the ‘Kanada’ warehouse facility for sorting and transporting back to Germany. To the prisoners, Canada was a country that symbolised wealth. They, therefore, gave the ironic name Kanada (the German spelling of Canada) to the warehouse area as it was full of possessions, clothing and jewellery.

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.

Oscar Schindler rose to the highest level of humanity, walked through the bloody mud of the Holocaust without soiling his soul, his compassion, his respect for human life -  and gave his Jews a second chance at life. He miraculously managed to do it and pulled it off by using the very same talents that made him a war profiteer - his flair for presentation, bribery, and grand gestures.

I visited both Auschwitz 1 and 2 Birkenau in November, it was a cold, grey, miserable day. As I walked around camp 2 I couldn't speak nor could my friend. The full horror and evidence of the past was right in front of me and I still found it difficult to process. Let us never forget all those people regardless of nationality, race or gender who died but let us remember they were all someones relation.
The driver promptly opened the throttle wide and drove straight into the nearest bushes. He had only gone a few yards, however, when the tank slid down a steep slope on the western edge of the wood and finally stopped, canted over on its side, in such a position that the enemy, whose guns were in position about 500 yards away on the edge of the next wood, could not fail to see it. I had been wounded in the right check by a small splinter from the shell which had landed in the periscope. It was not serious though it bled a great deal.
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.
Modern blitzkrieg was introduced by the German Army as a rational response to the stagnant trench warfare that characterized most of the fighting on the Western Front during World War I. Battles like Verdun or Passchendaele proved the war was nothing more than a meat grinder, and attacks from both sides only further proved the futility of the conflict.
Germany’s plans to attack the USSR were heavily influenced by Adolf Hitler’s racist, anti-Semitic and anti-Bolshevik postulates, which he had largely formulated much earlier in his agenda-setting book Mein Kampf. Joseph Stalin failed to fully take into account the highly ideological nature of Hitler’s political and military-strategic thinking; this led to mistakes in interpreting the Third Reich’s plans vis-a-vis the Soviet Union.
The British army took lessons from the successful infantry and artillery offensives on the Western Front in late 1918. To obtain the best co-operation between all arms, emphasis was placed on detailed planning, rigid control and adherence to orders. Mechanization of the army was considered a means to avoid mass casualties and indecisive nature of offensives, as part of a combined-arms theory of war.[35][36] The four editions of Field Service Regulations published after 1918 held that only combined-arms operations could create enough fire power to enable mobility on a battlefield. This theory of war also emphasized consolidation, recommending caution against overconfidence and ruthless exploitation.[37]
The St. Louis arrived in Havana harbor on May 27th. Of the 937 passengers on board, only 28 passengers were allowed into Cuba. 22 of these passengers were Jewish and had valid U.S. visas, 4 were Spanish citizens and 2 were Cuban nationals, all with valid documents. This story gained a lot of publicity; it was spread throughout Europe and the United States. The U.S. newspapers reported the story compassionately, but only a handful suggested that the refugees should come to the United States. The United States government decided not to take the steps to permit the passengers into the country.
The concentration and death-camp complex at Auschwitz-Birkenau was the largest killing center in the entire Nazi universe; the very heart of their system. Of the many sub-camps affiliated with Auschwitz, Birkenau, or Auschwitz II, was by far the largest. The main camp, Auschwitz I was on the outskirts of the Polish city Oswiecim. Birkenau was in a suiburb named Zasole.
After the selection process was complete, those too ill or too young to walk to the crematoria were transported there on trucks or killed on the spot with a bullet to the head.[168][169] The belongings of the arrivals were seized by the SS and sorted in an area of the camp called "Canada", so called because Canada was seen as a land of plenty. Many of the SS at the camp enriched themselves by pilfering the confiscated property.[170]
When asked, Schindler told that his metamorphosis during the war was sparked by the shocking immensity of the Final Solution. In his own words: "I hated the brutality, the sadism, and the insanity of Nazism. I just couldn't stand by and see people destroyed. I did what I could, what I had to do, what my conscience told me I must do. That's all there is to it. Really, nothing more."
The soldiers also found warehouses containing 836,525 items of women clothing, 348,820 items of men clothing, 43,525 pairs of shoes and vast numbers of toothbrushes, glasses and other personal effects. They found also 460 artificial limbs and seven tons of human hair shaved from Jews before they were murdered. The human hairs were used by the company “Alex Zink” (located in Bavaria) for confection of cloth. This company was paying the Nazi’s 50 pfennig per kilo of human hair.
In June 1945 the Soviet authorities took over Auschwitz I and converted it into a POW camp for German prisoners. The hospital had to move beyond the camp perimeter into former administrative buildings, where it functioned until October 1945.[253] Many of the barracks at Birkenau were taken apart by civilians, who used the materials to rebuild their own homes, which had been levelled out in the construction of Auschwitz II. The poorest residents sifted the crematoria ashes in search of nuggets from melted gold, before warning shots were fired.[254] The POW camp for German prisoners of war was used until 1947 by the Soviet NKVD (People's Commissariat for Internal Affairs).[255] The NKVD and its Polish counterpart, the MBP, used the Auschwitz Neu-Dachs sub-camp at Jaworzno to the north of Oświęcim as a concentration camp from 1945 to 1956.[256] The Soviets dismantled and exported the IG Farben factories to the USSR.[257] Meanwhile, Soviet and Polish investigators worked to document the war crimes of the SS.[258] After the site became a museum in 1947, exhumation work lasted for more than a decade.[184]
Almost all Jews within areas occupied by the Germans were killed. There were 3,020,000 Jews in the Soviet Union in 1939, and the losses were 1–1.1 million.[400] Around one million Jews were killed by the Einsatzgruppen in the occupied Soviet territories.[401][402] Of Poland's 3.3 million Jews, about 90 percent were killed.[369] Many more died in the ghettos of Poland before they could be deported.[403] The death camps accounted for half the number of Jews killed; 80–90 percent of death-camp victims are estimated to have been Jews.[394] At Auschwitz-Birkenau the Jewish death toll was 1.1 million;[286][404] Treblinka 870,000–925,000;[405] Bełżec 434,000–600,000;[406][287] Chełmno 152,000–320,000;[407][288] Sobibór 170,000–250,000;[408][291] and Majdanek 79,000.[289]
In the 1930s, the political landscape of Europe changed dramatically with the rise of Adolf Hitler and the German Nazi Party. Sensing the shift in political momentum, Schindler joined a local pro-Nazi organization and began collecting intelligence for the German military. He was arrested by Czech authorities in 1938, charged with spying and sentenced to death but was released shortly thereafter, when Germany annexed the Sudetenland. Schindler would take advantage of this second chance.
In October 1939 Hitler signed a "euthanasia decree" backdated to 1 September 1939 that authorized Reichsleiter Philipp Bouhler, the chief of Hitler's Chancellery, and Karl Brandt, Hitler's personal physician, to carry out a program of involuntary "euthanasia"; after the war this program was named Aktion T4.[98] It was named after Tiergartenstraße 4, the address of a villa in the Berlin borough of Tiergarten, where the various organizations involved were headquartered.[99] T4 was mainly directed at adults, but the "euthanasia" of children was also carried out.[100] Between 1939 and 1941, 80,000 to 100,000 mentally ill adults in institutions were killed, as were 5,000 children and 1,000 Jews, also in institutions. In addition there were specialized killing centres, where the deaths were estimated at 20,000, according to Georg Renno, the deputy director of Schloss Hartheim, one of the "euthanasia" centers, or 400,000, according to Frank Zeireis, the commandant of the Mauthausen concentration camp.[101] Overall, the number of mentally and physically handicapped murdered was about 150,000.[102]

Several protective zones surround components of the World Heritage property and function de facto as buffer zones. They are covered by local spatial development plans, which are consulted by the Regional Monuments Inspector. The management of the property’s setting is the responsibility of the local government of the Town and Commune of Oświęcim. For better management and protection of the attributes of the Outstanding Universal Value of the property, especially for the proper protection of its setting, a relevant management plan must be put into force.
The orders for the final evacuation and liquidation of the camp were issued in mid-January 1945. The Germans left behind in the main Auschwitz camp, Birkenau and in Monowitz about 7,000 sick or incapacitated who they did not expect would live for long; the rest, approximately 58,000 people, were evacuated by foot into the depths of the Third Reich.
After the Allied landings at Normandy, the Germans began a counter-offensive to overwhelm the landing force with armoured attacks but these failed for lack of co-ordination and Allied superiority in anti-tank defence and in the air. The most notable attempt to use deep penetration operations in Normandy was Operation Luttich at Mortain, which only hastened the Falaise Pocket and the destruction of German forces in Normandy. The Mortain counter-attack was defeated by the US 12th Army Group with little effect on its own offensive operations.[108]
You can visit the site on your own (highly recommended because you can go at your own pace, see what you want to see and have a much more meaningful experience) if you arrive before the guided tours start. Another option is to visit the Auschwitz II-Birkenau site first and then return after the guided tours finish to the first camp to avoid having to use the tour. The Auschwitz II-Birkenau site is open for visitors without the guide during the opening hours of the Memorial.
The gas chambers in the Auschwitz complex constituted the largest and most efficient extermination method employed by the Nazis. Four chambers were in use at Birkenau, each with the potential to kill 6,000 people daily. They were built to look like shower rooms in order to confuse the victims. New arrivals at Birkenau were told that they were being sent to work, but first needed to shower and be disinfected. They would be led into the shower-like chambers, where they were quickly gassed to death with the highly poisonous Zyklon B gas.
Upon arrival in Gliwice and Wodzislaw, the prisoners were put on unheated freight trains and transported to concentration camps in Germany, particularly to Flossenbürg, Sachsenhausen, Gross-Rosen, Buchenwald, Dachau, and also to Mauthausen in Austria. The rail journey lasted for days. Without food, water, shelter, or blankets, many prisoners did not survive the transport.

Finland was pressured in 1942 to hand over its 150–200 non-Finnish Jews to Germany. After opposition from the government and public, eight non-Finnish Jews were deported in late 1942; only one survived the war.[173] Japan had little antisemitism in its society and did not persecute Jews in most of the territories it controlled. Jews in Shanghai were confined, but despite German pressure they were not killed.[174]
The first “bunker,” with two sealed rooms, operated from January 1942 to the end of that year. The second, with four air tight rooms, became redundant in the spring of 1943, but remained standing and was used again in the autumn of 1944 when extra “capacity” was needed for the murder of Hungarian Jews and the liquidation of the ghettos. The second measured about 1.134 square feet. The victims murdered in the “bunkers” were first obliged to undress in temporary wooden barracks erected nearby. Their bodies were taken out of the gas chambers and pushed to pits where they were burned in the open.
By the spring of 1945, German leadership was dissolving amid internal dissent, with Goering and Himmler both seeking to distance themselves from Hitler and take power. In his last will and political testament, dictated in a German bunker that April 29, Hitler blamed the war on “International Jewry and its helpers” and urged the German leaders and people to follow “the strict observance of the racial laws and with merciless resistance against the universal poisoners of all peoples”–the Jews. The following day, he committed suicide. Germany’s formal surrender in World War II came barely a week later, on May 8, 1945.
Writer Herbert Steinhouse, who interviewed him in 1948, wrote that "Schindler's exceptional deeds stemmed from just that elementary sense of decency and humanity that our sophisticated age seldom sincerely believes in. A repentant opportunist saw the light and rebelled against the sadism and vile criminality all around him."[39] In a 1983 television documentary, Schindler was quoted as saying, "I felt that the Jews were being destroyed. I had to help them; there was no choice."[90]
