It should be noted that early forms of Blitzkrieg were used in the First World War - most notably by General Alexei Brusilov in Russia's Brusilov Offensive of 1916 and Britain's General Allenby in the Battle of Megiddo in September 1918, making heavy use of armored vehicles, quick-strike cavalry attacks, and aerial bombardment to facilitate a swift and decisive victory. The Germans themselves used a variation of such tactics in their 1918 Spring Offensive.

After the liquidation of the Polish state and its institutions, the fundamental goal of German policy in occupied Poland was the exploitation of material and labor resources, and the removal of the local Polish population and ethnic minorities. This was done through expulsion and systematic extermination. The Polish lands were to be completely germanized, through German settlement in the depopulated area.
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.
In March 1941, Himmler ordered a second, larger complex to be built next to the original camp. It was called Auschwitz II - Birkenau. The camp at Birkenau was divided into subsections surrounded by electric fences with barbed wire. During 1943 and 1944 the BIIb section became the location of the „Terezín family camp“. At its summit, Birkenau had over 100 000 inmates. In March 1942, the Auschwitz III camp was set up at nearby Monowitz, also known as Buna Monowitz. German company I.G. Farben set up a synthetic rubber factory there, in which it used the prisoners' slave labour. Auschwitz also had a further 45 auxiliary camps, where prisoners were forced to engage in slave labour, mostly for German companies.
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.
Information about Auschwitz became available to the Allies as a result of reports by Captain Witold Pilecki of the Polish Home Army (Armia Krajowa), who volunteered to be imprisoned there in 1940. As "Thomasz Serfiński", he allowed himself to be arrested in Warsaw and spent 945 days in the camp, from 22 September 1940[199] until his escape on 27 April 1943. Michael Fleming writes that Pilecki was instructed to sustain morale, organize food, clothing and resistance, prepare to take over the camp if possible, and smuggle information out to the Polish military.[200] Pilecki called his resistance movement Związek Organizacji Wojskowej (ZOW, "Union of Military Organization").[199]

"Blitzkrieg" has since expanded into multiple meanings in more popular usage. From its original military definition, "blitzkrieg" may be applied to any military operation emphasizing the surprise, speed, or concentration stressed in accounts of the Invasion of Poland. During the war, the Luftwaffe terror bombings of London came to be known as The Blitz. Similarly, blitz has come to describe the " blitz" (rush) tactic of American football, and the blitz form of chess in which players are allotted very little time. Blitz or blitzkrieg is used in many other non-military contexts.

The requirement for focus of this offense-oriented attack also represents the tactic’s Achilles’ heel. With Operation Barbarossa (the Nazi invasion of Russia) the Germans tried to apply Blitzkrieg on a front that was so wide that any subsequent attempt to encircle the enemy following penetration proved ineffective, leaving huge gaps for the Russian army to respond.
Schlieffen's ideas were largely aimed at operational-level leaders, that is, the commanders of Germany's divisions and army corps. The biggest problems in World War One, however, were at the lower, tactical level. And the German solution to these problems was to apply Schlieffen's operational principles to small units as well as to large ones. Thus, by decentralising command and by increasing the firepower of the infantry, they created a large number of platoon-sized units capable of independent action on the battlefield.
From 1933 until 1938, most of the people held in concentration camps were political prisoners and people the Nazis labeled as "asocial." These included the disabled, the homeless, and the mentally ill. After Kristallnacht in 1938, the persecution of Jews became more organized. This led to the exponential increase in the number of Jews sent to concentration camps.
December 8, 1941 - In occupied Poland, near Lodz, Chelmno extermination camp becomes operational. Jews taken there are placed in mobile gas vans and driven to a burial place while carbon monoxide from the engine exhaust is fed into the sealed rear compartment, killing them. The first gassing victims include 5,000 Gypsies who had been deported from the Reich to Lodz.
In the Sinai and Palestine Campaign, operations involved some aspects of what would later be called blitzkrieg.[38] Key elements in the "blitzkrieg warfare" at the decisive Battle of Megiddo included concentration, surprise and speed; success depended on attacking only in terrain favoring the movement of large formations around the battlefield and tactical improvements in the British artillery and infantry attack.[39][40] General Edmund Allenby used infantry to attack the strong Ottoman front line in co-operation with supporting artillery, augmented by the guns of two destroyers.[41][42] Through constant pressure by infantry and cavalry, two Ottoman armies in the Judean Hills were kept off-balance and virtually encircled during the Battles of Sharon and Nablus (Battle of Megiddo).[43]
Although effective in quick campaigns against Poland and France, mobile operations could not be sustained by Germany in later years. Strategies based on manoeuvre have the inherent danger of the attacking force overextending its supply lines, and can be defeated by a determined foe who is willing and able to sacrifice territory for time in which to regroup and rearm, as the Soviets did on the Eastern Front (as opposed to, for example, the Dutch who had no territory to sacrifice). 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.[75] 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 and blockade. 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.[76]
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.
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]
"Rothenburg [a subordinate tank commander] now drove off through a hollow to the left with the five tanks which were to accompany the infantry, thus giving these tanks a lead of 100 to 150 yards. There was no sound of enemy fire. Some 20 to 30 tanks followed up behind. When the commander of the five tanks reached the rifle company on the southern edge of Onhaye wood, Colonel Rothenburg moved off with his leading tanks along the edge of the wood going west. We had just reached the southwest corner of the wood and were about to cross a low plantation, from which we could see the five tanks escorting the infantry below us to our left front, when suddenly we came under heavy artillery and anti-tank gunfire from the west. Shells landed all round us and my tank received two hits one after the other, the first on the upper edge of the turret and the second in the periscope.
In France Jews under Fascist Italian occupation in the southeast fared better than the Jews of Vichy France, where collaborationist French authorities and police provided essential support to the understaffed German forces. The Jews in those parts of France under direct German occupation fared the worst. Although allied with Germany, the Italians did not participate in the Holocaust until Germany occupied northern Italy after the overthrow of Fascist leader Benito Mussolini in 1943.
When Spielberg finally decided to make Schindler’s List, it had taken him so long that Sheinberg and Universal balked. The relatively low-budget $23 million three-hour black-and-white Holocaust movie was too much of a risk, so they asked Spielberg to make another project that had been brewing at the studio: Jurassic Park. Make the lucrative summer movie first, they said, and then he could go and make his passion project. Spielberg agreed, and both movies were released in 1993; Jurassic Park in June and Schindler’s List in December.
Before the Nazis began their mass slaughter of Jews, they created a number of laws that separated Jews from society. Especially potent was the law that forced all Jews to wear a yellow star upon their clothing. The Nazis also made laws that made it illegal for Jews to sit or eat in certain places and placed a boycott on Jewish-owned stores. Learn more about the persecution of Jews before the death camps.
The invasion of France consisted of two phases, Operation Yellow (Fall Gelb) and Operation Red. Yellow opened with a feint conducted against the Netherlands and Belgium by two armoured corps and paratroopers. Three days later, the main effort of Panzer Group von Kleist attacked through the Ardennes and achieved a breakthrough with air support. The group raced to the coast of the English Channel, dislodging the British Expeditionary Force, Belgian Army, and some divisions of the French Army. The motorized units initially advanced far beyond the following divisions. When the German motorized forces were met with a counterattack at the Battle of Arras (1940), British tanks with heavy armour (Matilda I & IIs) created a brief panic in the German High Command. The motorized forces were halted outside the port city of Dunkirk which was being used to evacuate the Allied forces. Hermann Göring had promised his Luftwaffe would complete the job but aerial operations did not prevent the evacuation of the majority of Allied troops (which the British named Operation Dynamo); some 330,000 French and British. Operation Red then began with XV Panzer Corps attacking towards Brest and XIV Panzer Corps attacking south, east of Paris, towards Lyon, and XIX Panzer Corps completing the encirclement of the Maginot Line. The defending forces were hard pressed to organize any sort of counter-attack. The French forces were continually ordered to form new lines along rivers, often arriving to find the German forces had already passed them.
In the spring of 1941, German conglomerate I.G. Farben established a factory in which its executives intended to exploit concentration camp labor to manufacture synthetic rubber and fuels. I.G. Farben invested more than 700 million Reichsmarks (about 2.8 million US dollars in 1941 terms) in Auschwitz III. From May 1941 until July 1942, the SS had transported prisoners from Auschwitz I to the “Buna Detachment,” at first on foot and later by rail. (Between July and October 1942 there was a pause in transports, due to a typhus epidemic and quarantine.) With the construction of Auschwitz III in the autumn of 1942, prisoners deployed at Buna lived in Auschwitz III.

Despite being common in German and English-language journalism during World War II, the word Blitzkrieg was never used by the Wehrmacht as an official military term, except for propaganda.[9] According to David Reynolds, "Hitler himself called the term Blitzkrieg 'A completely idiotic word' (ein ganz blödsinniges Wort)".[11] Some senior officers, including Kurt Student, Franz Halder and Johann Adolf von Kielmansegg, even disputed the idea that it was a military concept. Kielmansegg asserted that what many regarded as blitzkrieg was nothing more than "ad hoc solutions that simply popped out of the prevailing situation". Student described it as ideas that "naturally emerged from the existing circumstances" as a response to operational challenges.[12] The Wehrmacht never officially adopted it as a concept or doctrine.[a]
German forces had begun evacuating many of the death camps in the fall of 1944, sending inmates under guard to march further from the advancing enemy’s front line. These so-called “death marches” continued all the way up to the German surrender, resulting in the deaths of some 250,000 to 375,000 people. In his classic book “Survival in Auschwitz,” the Italian Jewish author Primo Levi described his own state of mind, as well as that of his fellow inmates in Auschwitz on the day before Soviet troops arrived at the camp in January 1945: “We lay in a world of death and phantoms. The last trace of civilization had vanished around and inside us. The work of bestial degradation, begun by the victorious Germans, had been carried to conclusion by the Germans in defeat.”
In the summer of 1942, Germany launched another offensive in the southern USSR against Stalingrad and the Caucasus, the Soviets again lost tremendous amounts of territory, only to counter-attack once more during winter. German gains were ultimately limited by Hitler diverting forces from the attack on Stalingrad and driving towards the Caucasus oilfields simultaneously. The Wehrmacht became overstretched, although winning operationally, it could not inflict a decisive defeat as the durability of the Soviet Union's manpower, resources, industrial base and aid from the Western Allies began to take effect.[95]

The twin pairs of gas chambers were numbered II and III, and IV and V. The first opened on March 31, 1943, the last on April 4, 1943. The total area of the gas chambers was 2,255 square meters; the capacity of these crematoria was 4,420 people. Those selected to die were undressed in the undressing room and then pushed into the gas chambers. It took about 20 minutes for all the people to death. In II and III, the killings took place in underground rooms, and the corpses were carried to the five ovens by an electrically operated lift. Before cremation gold teeth and any other valuables, such as rings, were removed from the corpses. In IV and V the gas chambers and ovens were on the same level, but the ovens were so poorly built and the usage was so great that they repeatedly malfunctioned and had to be abandoned. The corpses were finally burned outside, in the open, as in 1943. Jewish sonderkommandos worked the crematoria under SS supervision.
Military trucks loaded with bread arrived on 28 January, and volunteers began to offer first aid and improvised assistance the following week.[249] The liberation of the camp received little Western press attention at the time. Laurence Rees attributes this to three factors: the previous discovery of similar crimes at the Majdanek concentration camp, competing news from the Allied summit at Yalta, and the Soviet Union's Marxist presentation of the camp "as the ultimate capitalist factory where the workers were dispensible", combined with its interest in minimizing attention to Jewish suffering.[252]
Those who arrived in Birkenau were driven out of the cattle wagons and put in rows … to this the band played, made up of the best musicians among the prisoners; they played, depending on the origins of the transport, Polish, Czech, or Hungarian folk music.  The band played, the SS pummelled, and you had no time to reflect … some were forced into the camp, the others into the crematoria.
Blitzkrieg   (German, literally lightning war or flash war) is a popular name for an offensive operational-level military doctrine which involves an initial bombardment followed by employment of mobile forces attacking with speed and surprise to prevent an enemy from implementing a coherent defense. The founding principles of these types of operations were developed in the 19th Century by various nations, and adapted in the years after World War I, largely by the German Wehrmacht, to incorporate modern weapons and vehicles as a method to help prevent trench warfare and linear warfare in future conflicts. The first practical implementations of these concepts coupled with modern technology were instituted by the Wehrmacht in the opening battles of World War II. While operations in Poland were rather conventional, subsequent battles — particularly the invasions of France, The Netherlands and initial operations in the Soviet Union — were effective owing to surprise penetrations, general enemy unpreparedness and an inability to react swiftly enough to German offensive operations. That the German Army quickly defeated numerically and technically superior enemies in France led many analysts to believe that a new system of warfare had been invented.
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]

Following the camp's liberation, the Soviet government issued a statement, on 8 May 1945, that four million people had been killed on the site, a figure based on the capacity of the crematoria and later regarded as too high.[184] Höss told prosecutors at Nuremberg that at least 2,500,000 people had been murdered in Auschwitz by gassing and burning, and that another 500,000 had died of starvation and disease.[185] He testified that the figure of over two million had come from Eichmann.[186][d] In his memoirs, written in custody, he wrote that he regarded this figure as "far too high. Even Auschwitz had limits to its destructive possibilities."[188] Raul Hilberg's 1961 work, The Destruction of the European Jews, estimated that up to 1,000,000 Jews had died in Auschwitz.[189]

The last part of an offensive operation was the destruction of un-subdued pockets of resistance, which had been enveloped earlier and by-passed by the fast-moving armoured and motorised spearheads. The Kesselschlacht 'cauldron battle' was a concentric attack on such pockets. It was here that most losses were inflicted upon the enemy, primarily through the mass capture of prisoners and weapons. During Operation Barbarossa, huge encirclements in 1941 produced nearly 3.5 million Soviet prisoners, along with masses of equipment.[66][f]
The complex, which divided into three main areas, was established by the Nazi’s in 1940 and was in use until its Allied liberation in 1945. Historians and analysts estimate the number of people murdered at Auschwitz somewhere between 2.1 million to 4 million, of whom the vast majority were Jews. The majority of prisoners held at Auschwitz were killed in the various gas chambers though many died from starvation, forced labor, disease, shooting squads, and heinous medical experiments.
In October 1980, Australian novelist Thomas Keneally had stopped into a leather goods shop off of Rodeo Drive after a book tour stopover from a film festival in Sorrento, Italy, where one of his books was adapted into a movie. When the owner of the shop, Leopold Page, learned that Keneally was a writer, he began telling him “the greatest story of humanity man to man.” That story was how Page, his wife, and thousands of other Jews were saved by a Nazi factory owner named Oskar Schindler during World War II.

Auschwitz II, located in the village of Birkenau, or Brzezinka, just outside OÅ›wiÄ™cim, was constructed in 1941 on the order of Heinrich Himmler (1900-45), commander of the “Schutzstaffel” (or Select Guard/Protection Squad, more commonly known as the SS), which operated all Nazi concentration camps and death camps. Birkenau, the biggest of the Auschwitz facilities, could hold some 90,000 prisoners. It also housed a group of bathhouses where countless people were gassed to death, and crematory ovens where bodies were burned. The majority of Auschwitz victims died at Birkenau.More than 40 smaller facilities, called subcamps, dotted the landscape and served as slave-labor camps. The largest of these subcamps, Monowitz, also known as Auschwitz III, began operating in 1942 and housed some 10,000 prisoners.
Overall 268,657 male and 131,560 female prisoners were registered in Auschwitz, 400,207 in total.[181] Many prisoners were never registered and much evidence was destroyed by the SS in the final days of the war, making the number of victims hard to ascertain.[182] Himmler visited the camp on 17 July 1942 and watched a gassing; a few days later, according to Höss's post-war memoir, Höss received an order from Himmler, via Adolf Eichmann's office and SS commander Paul Blobel, that "[a]ll mass graves were to be opened and the corpses burned. In addition the ashes were to be disposed of in such a way that it would be impossible at some future time to calculate the number of corpses burned."[183]

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.
