During the war, the Condor Legion undertook the bombing of Guernica which had a tremendous psychological effect on the populations of Europe. The results were exaggerated, and the Western Allies concluded that the "city-busting" techniques were now a part of the German way in war. The targets of the German aircraft were actually the rail lines and bridges. But lacking the ability to hit them with accuracy (only three or four Ju 87s saw action in Spain), a method of carpet bombing was chosen resulting in heavy civilian casualties.[80]

After invading Poland, the Germans established ghettos in the incorporated territories and General Government to confine Jews.[143] The ghettos were formed and closed off from the outside world at different times and for different reasons.[196][197] For example, the Łódź ghetto was closed in April 1940,[143] to force the Jews inside to give up money and valuables;[198] the Warsaw ghetto was closed for health considerations (for the people outside, not inside, the ghetto),[199] but this did not happen until November 1940;[143] and the Kraków ghetto was not established until March 1941.[200] The Warsaw Ghetto contained 380,000 people[143] and was the largest ghetto in Poland; the Łódź Ghetto was the second largest,[201] holding between 160,000[202] to 223,000.[203] Because of the long drawn-out process of establishing ghettos, it is unlikely that they were originally considered part of a systematic attempt to eliminate Jews completely.[204]

Guderian argued that the tank was the decisive weapon of 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." Guderian additionally required that tactical radios be widely used to facilitate co-ordination and command.

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.
Historical accuracy is pushed to the edge as each unit is endowed with the actual capabilities and characteristics that existed at the time. Details such as the thickness of a tank's armor down to the range of infantry rifles add a level of previously unprecedented realism. Each campaign has been meticulously researched to provide an accurate depiction of the battles that took place, while still maintaining the flexibility (and fun!) necessary to let you play the way you want.
Following the invasion of the Soviet Union in June 1941, Einsatzgruppen and, later, militarized battalions of Order Police officials, moved behind German lines to carry out mass-murder operations against Jews, Roma, and Soviet state and Communist Party officials. German SS and police units, supported by units of the Wehrmacht and the Waffen SS, murdered more than a million Jewish men, women, and children, and hundreds of thousands of others.
In 1995, David Glantz stated that for the first time, blitzkrieg was defeated in summer and the opposing Soviet forces were able to mount a successful counter-offensive.[98] The Battle of Kursk ended with two Soviet counter-offensives and the revival of deep operations.[98] In the summer of 1944, the Red Army destroyed Army Group Centre in Operation Bagration, using combined-arms tactics for armour, infantry and air power in a coordinated strategic assault, known as deep operations, which led to an advance of 600 kilometres (370 mi) in six weeks.[106]

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.”

The concepts associated with the term blitzkrieg—deep penetrations by armour, large encirclements, and combined arms attacks—were largely dependent upon terrain and weather conditions. Where the ability for rapid movement across "tank country" was not possible, armoured penetrations often were avoided or resulted in failure. Terrain would ideally be flat, firm, unobstructed by natural barriers or fortifications, and interspersed with roads and railways. If it were instead hilly, wooded, marshy, or urban, armour would be vulnerable to infantry in close-quarters combat and unable to break out at full speed.[citation needed] Additionally, units could be halted by mud (thawing along the Eastern Front regularly slowed both sides) or extreme snow. Operation Barbarossa helped confirm that armour effectiveness and the requisite aerial support were dependent on weather and terrain.[68] It should however be noted that the disadvantages of terrain could be nullified if surprise was achieved over the enemy by an attack through areas considered natural obstacles, as occurred during the Battle of France when the German blitzkrieg-style attack went through the Ardennes.[69] Since the French thought the Ardennes unsuitable for massive troop movement, particularly for tanks, they were left with only light defences which were quickly overrun by the Wehrmacht. The Germans quickly advanced through the forest, knocking down the trees the French thought would impede this tactic.[70]

Auschwitz, the largest and arguably the most notorious of all the Nazi death camps, opened in the spring of 1940. Its first commandant was Rudolf Höss (1900-47), who previously had helped run the Sachsenhausen concentration camp in Oranienburg, Germany. Auschwitz was located on a former military base outside OÅ›wiÄ™cim, a town in southern Poland situated near Krakow, one of the country’s largest cities. During the camp’s construction, nearby factories were appropriated and all those living in the area were forcibly ejected from their homes, which were bulldozed by the Nazis.
Most of the Jewish ghettos of General Government were liquidated in 1942–1943, and their populations shipped to the camps for extermination.[349][350][t] About 42,000 Jews were shot during the Operation Harvest Festival on 3–4 November 1943.[351] At the same time, rail shipments arrived regularly from western and southern Europe at the extermination camps.[352] Few Jews were shipped from the occupied Soviet territories to the camps: the killing of Jews in this zone was mostly left in the hands of the SS, aided by locally recruited auxiliaries.[353][u]
Inmates at Birkenau numbered around 100,000 at their peak. They were of many different nationalities, but the vast majority of those that entered the camp were unregistered Jews, many of whom were immediately sent to their deaths in the gas chambers. Women and children stood the least chance of survival, and many died even before arriving at Birkenau due to the appalling conditions of the railway journeys. The unloading platform, where the brisk selection process was conducted, remains. Apart from physically fit men (who often perished later from the rigours of the camp) it was often only an accident of birth that merited a possibility of survival. Large numbers of twins survived until liberation as they were objects of interest to the research of Dr. Josef Mengele - a man disliked even by his Nazi peers.
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]
Les enceintes, les barbelés, les miradors, les baraquements, les potences, les chambres à gaz et les fours crématoires de l'ancien camp de concentration et d'extermination d'Auschwitz-Birkenau, le plus vaste du IIIe Reich, attestent les conditions dans lesquelles fonctionnait le génocide hitlérien. Selon des recherches historiques, 1,1 à 1,5 million de personnes – dont de très nombreux Juifs – furent systématiquement affamées, torturées et assassinées dans ce camp, symbole de la cruauté de l'homme pour l'homme au XXe siècle.
Buses leave Auschwitz I for Birkenau at a half past the hour, every hour. It costs two zloty and takes no more than five minutes. The experience of the camp is very different from Auschwitz I. For one thing it is much larger, covering over four hundred acres. It also retains the air of the place as it was when abandoned to a greater degree than the former camp. Some sixty seven buildings have survived virtually intact, and the interiors, with their stark wooden furnishings, take you right back to the war era. The other buildings remain as they were - some burnt to the ground and others massed up in heaps of rubble.
"Blitzkrieg" is a German compound meaning "lightning war". The word did not enter official terminology of the Wehrmacht either before or during the war, even though it was already used in the military Journal "Deutsche Wehr" in 1935, in the context of an article on how states with insufficient food and raw materials supply can win a war. Another appearance is in 1938 in the "Militär-Wochenblatt", where Blitzkrieg is defined as a "strategic attack", carried out by operational use of tanks, air force, and airborne troops. Karl-Heinz Frieser in his book 'Blitzkrieg Legende', who researched the origin of the term and found the above examples, points out that the pre-war use of the term is rare, and that it practically never entered official terminology throughout the war.

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.
Even before the Nazis came to power in Germany in 1933, they had made no secret of their anti-Semitism. As early as 1919 Adolf Hitler had written, “Rational anti-Semitism, however, must lead to systematic legal opposition.…Its final objective must unswervingly be the removal of the Jews altogether.” In Mein Kampf (“My Struggle”; 1925–27), Hitler further developed the idea of the Jews as an evil race struggling for world domination. Nazi anti-Semitism was rooted in religious anti-Semitism and enhanced by political anti-Semitism. To this the Nazis added a further dimension: racial anti-Semitism. Nazi racial ideology characterized the Jews as Untermenschen (German: “subhumans”). The Nazis portrayed the Jews as a race and not as a religious group. Religious anti-Semitism could be resolved by conversion, political anti-Semitism by expulsion. Ultimately, the logic of Nazi racial anti-Semitism led to annihilation.
In early 1942 the Nazis built killing centres at Treblinka, Sobibor, and Belzec in occupied Poland. The death camps were to be the essential instrument of the “final solution.” The Einsatzgruppen had traveled to kill their victims. With the killing centres, the process was reversed. The victims were taken by train, often in cattle cars, to their killers. The extermination camps became factories producing corpses, effectively and efficiently, at minimal physical and psychological cost to German personnel. Assisted by Ukrainian and Latvian collaborators and prisoners of war, a few Germans could kill tens of thousands of prisoners each month. At Chelmno, the first of the extermination camps, the Nazis used mobile gas vans. Elsewhere they built permanent gas chambers linked to the crematoria where bodies were burned. Carbon monoxide was the gas of choice at most camps. Zyklon-B, an especially lethal killing agent, was employed primarily at Auschwitz and later at Majdanek.

Adam Tooze wrote that the German economy was being prepared for a long war. The expenditure for this war was extensive and put the economy under severe strain. The German leadership were concerned less with how to balance the civilian economy and the needs of civilian consumption but to figure out how to best prepare the economy for total war. Once war had begun, Hitler urged his economic experts to abandon caution and expend all available resources on the war effort but the expansion plans only gradually gained momentum in 1941. Tooze wrote that the huge armament plans in the pre-war period did not indicate any clear-sighted blitzkrieg economy or strategy.[134]
By the war’s end, approximately 1.25 million people had been killed here, more than 90 per cent of them Jewish.  Birkenau was also where the infamous Dr Josef Mengele performed many of his experiments on pregnant women, dwarves, and twins.  As was the case in the other camps of Auschwitz, there was a mass evacuation immediately before the Soviets reached the camp.  Only a few thousand prisoners remained to be liberated when the Soviets arrived on 27 January 1945.
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.
Uniquely at Auschwitz, prisoners were tattooed with a serial number, on their left breast for Soviet prisoners of war[97] and on the left arm for civilians.[98] Categories of prisoner were distinguishable by triangular pieces of cloth (German: Winkel) sewn onto on their jackets below their prisoner number. Political prisoners (Schutzhäftlinge or Sch), mostly Poles, had a red triangle, while criminals (Berufsverbrecher or BV) were mostly German and wore green. Asocial prisoners (Asoziale or Aso), which included vagrants, prostitutes and the Roma, wore black. Purple was for Jehovah's Witnesses (Internationale Bibelforscher-Vereinigung or IBV)'s and pink for gay men, who were mostly German.[99] An estimated 5,000–15,000 gay men prosecuted under German Penal Code Section 175 (proscribing sexual acts between men) were detained in concentration camps, of which an unknown number were sent to Auschwitz.[100] Jews wore a yellow badge, the shape of the Star of David, overlaid by a second triangle if they also belonged to a second category. The nationality of the inmate was indicated by a letter stitched onto the cloth. A racial hierarchy existed, with German prisoners at the top. Next were non-Jewish prisoners from other countries. Jewish prisoners were at the bottom.[101]
The first such extermination camps were introduced during Operation Reinhardt, which targeted the elimination of the Jewish people within the General Government of Occupied Poland and Ukraine. After the first killing center open at Chelmno, the use of these extermination tactics spread quickly. At the height of deportations, the Birkenau killing center murdered 6,000 Jews a day.
Entrance is free, without a ticket, though donations are encouraged. Because of the large numbers of visitors entry to the Auschwitz-I site is exclusively on a guided group basis during the middle part of the day - as of 2019, between 10am and 12pm during December, between 10am and 1pm in November, January, February and March, between 10am and 4pm in April, May, September and October, and between 9am and 5pm in June, July and August.

Płaszów concentration camp opened in March 1943 on the former site of two Jewish cemeteries on Jerozilimska Street, about 2.5 kilometres (1.6 mi) from the DEF factory.[49] In charge of the camp was SS-Hauptsturmführer Amon Göth, a sadist who would shoot inmates of the camp at random.[48] Inmates at Płaszów lived in constant fear for their lives.[50] Emilie Schindler called Göth "the most despicable man I have ever met."[51]
