By Guderian's account he single-handedly created the German tactical and operational methodology. Between 1922 and 1928 Guderian wrote a number of articles concerning military movement. As the ideas of making use of the combustible engine in a protected encasement to bring mobility back to warfare developed in the German army, Guderian was a leading proponent of the formations that would be used for this purpose. He was later asked to write an explanatory book, which was titled Achtung Panzer! (1937). In it he explained the theories of the tank men and defended them.

The Roma refer to the genocide of the Romani people as the Pořajmos.[414] Because they are traditionally a private people with a culture based on oral history, less is known about their experience than that of any other group.[415] Bauer writes that this can be attributed to the Roma's distrust and suspicion, and to their humiliation because some of the taboos in Romani culture regarding hygiene and sex were violated at Auschwitz.[416] In May 1942, the Roma were placed under similar laws to the Jews. On 16 December 1942, Himmler issued a decree that "Gypsy Mischlinge [mixed breeds], Roma Gypsies, and members of the clans of Balkan origins who are not of German blood" should be sent to Auschwitz, unless they had served in the Wehrmacht.[417] He adjusted the order on 15 November 1943; in the occupied Soviet areas, "sedentary Gypsies and part-Gypsies are to be treated as citizens of the country. Nomadic Gypsies and part-Gypsies are to be placed on the same level as Jews and placed in concentration camps."[418] Bauer argues that this adjustment reflected Nazi ideology that the Roma, originally an Aryan population, had been "spoiled" by non-Romani blood.[419]
Following Germany's military reforms of the 1920s, Heinz Guderian emerged as a strong proponent of mechanized forces. Within the Inspectorate of Transport Troops, Guderian and colleagues performed theoretical and field exercise work. There was opposition from many officers who gave primacy to the infantry or simply doubted the usefulness of the tank. Among them was Chief of the General Staff Ludwig Beck (1935–38), who skeptical that armored forces could be decisive. Nonetheless, the panzer divisions were established during his tenure.
This photographic exhibit shows the camp as it exists today, empty and quiet. Many hundreds of thousands of people visit here from all over the world each year. Every day one can observe, in addition to people of many lands, numerous bus-loads of Polish students walking the camp with their teachers and guides. These days, thanks to a new treaty and better relations between Israel and Poland, one can observe many Israeli youth with their teachers, visiting the camp.
With the deportations from Hungary, the role of Auschwitz-Birkenau in the German plan to murder the Jews of Europe achieved its highest effectiveness. Between late April and early July 1944, approximately 440,000 Jews were deported from Hungary. Of the nearly 426,000 Hungarian Jews deported to Auschwitz, approximately 320,000 of them were sent directly to the gas chambers in Auschwitz-Birkenau. They deployed approximately 110,000 at forced labor in the Auschwitz camp complex. The SS authorities transferred many of these Hungarian Jewish forced laborers within weeks of their arrival in Auschwitz to other concentration camps in Germany and Austria.
The most notorious physician was Josef Mengele, an SS officer who became the Auschwitz camp doctor on 30 May 1943.[54] Interested in genetics[54] and keen to experiment on twins, he would pick out subjects from the new arrivals during "selection" on the ramp, shouting "Zwillinge heraus!" (twins step forward!).[55] They would be measured, killed, and dissected. One of Mengele's assistants said in 1946 that he was told to send organs of interest to the directors of the "Anthropological Institute in Berlin-Dahlem". This is thought to refer to Mengele's academic supervisor, Otmar Freiherr von Verschuer , director from October 1942 of the Kaiser Wilhelm Institute of Anthropology, Human Heredity, and Eugenics in Berlin-Dahlem.[56][55][i] Mengele's experiments included placing subjects in pressure chambers, testing drugs on them, freezing them, attempting to change their eye color by injecting chemicals into children's eyes, and amputations and other surgeries.[59]
Initially, arrivals at Auschwitz-Birkenau would be unloaded on a ramp alongside the main railway lines at Oświęcim. The prisoners would then walk the short distance to the camp. However, in preparation for the arrival of 440,000 Hungarian Jews during the spring of 1944, railway tracks were laid right into the camp, through the now infamous gatehouse building.
Thus although the Nazi 'Final Solution' was one genocide among many, it had features that made it stand out from all the rest as well. Unlike all the others it was bounded neither by space nor by time. It was launched not against a local or regional obstacle, but at a world-enemy seen as operating on a global scale. It was bound to an even larger plan of racial reordering and reconstruction involving further genocidal killing on an almost unimaginable scale, aimed, however, at clearing the way in a particular region – Eastern Europe – for a further struggle against the Jews and those the Nazis regarded as their puppets. It was set in motion by ideologues who saw world history in racial terms. It was, in part, carried out by industrial methods. These things all make it unique.

On May 19th, 1939, the S.S. St. Louis sailed from Hamburg, Germany to Havana, Cuba with 937 passengers; almost all of them were Jews escaping with their lives. This was one of the last ships that left Germany before the outbreak of World War II. Most of the passengers had applied for U.S. visas and were only planning on staying in Cuba until they could enter into the United States. The U.S. State Department in Washington, the U.S. consulate in Havana, and the owner of the St. Louis were aware that they might not be able to enter Cuba, but the passengers were never told.
Jewish deportees arriving at Auschwitz-Birkenau immediately underwent selection. The SS staff chose some of the able-bodied for forced labor and sent the rest directly to the gas chambers, which were disguised as shower installations to mislead the victims. The belongings of all deportees were confiscated and sorted in the "Kanada" (Canada) warehouse for shipment back to Germany. Canada symbolized wealth to the prisoners.

September 21, 1939 - Heydrich issues instructions to SS Einsatzgruppen (special action squads) in Poland regarding treatment of Jews, stating they are to be gathered into ghettos near railroads for the future "final goal." He also orders a census and the establishment of Jewish administrative councils within the ghettos to implement Nazi policies and decrees.

In the first few decades after the Holocaust, scholars argued that it was unique as a genocide in its reach and specificity.[476] This began to change in the 1980s during the West German Historikerstreit ("historians' dispute"), an attempt to re-position the Holocaust within German historiography. Ernst Nolte triggered the dispute in June 1986 with an article in the Frankfurter Allgemeine Zeitung: "Vergangenheit, die nicht vergehen will: Eine Rede, die geschrieben, aber nicht mehr gehalten werden konnte" ("The past that will not pass: A speech that could be written but not delivered"), in which he compared Auschwitz to the Gulag and suggested that the Holocaust was a response to Hitler's fear of the Soviet Union: "Was the Bolshevik murder of an entire class not the logical and factual prius of the 'racial murder' of National Socialism? ... Was the source of Auschwitz a past that would not go away?"[aa]
After the Nuremberg war crimes trials finished, the United States spearheaded the effort to end genocide and become a champion for the prevention of crimes against humanity. The U.S. pushed for greater international effort, helping to draft the 1948 Genocide Convention. President Harry Truman addressed Congress urging the Convention’s passage. He stressed the role the United States had to play in “outlawing the world-shocking crime of genocide.”
The wounds of the Holocaust–known in Hebrew as Shoah, or catastrophe–were slow to heal. Survivors of the camps found it nearly impossible to return home, as in many cases they had lost their families and been denounced by their non-Jewish neighbors. As a result, the late 1940s saw an unprecedented number of refugees, POWs and other displaced populations moving across Europe.

Ghettos were intended to be temporary until the Jews were deported to other locations, which never happened. Instead, the inhabitants were sent to extermination camps. The ghettos were, in effect, immensely crowded prisons serving as instruments of "slow, passive murder."[216] Though the Warsaw Ghetto contained 30% of Warsaw's population, it occupied only 2.5% of the city's area, averaging over 9 people per room.[217] Between 1940 and 1942, starvation and disease, especially typhoid, killed many in the ghettos.[218] Over 43,000 Warsaw ghetto residents, or one in ten of the total population, died in 1941;[219] in Theresienstadt, more than half the residents died in 1942.[216]
Blitzkrieg (German: "lightning war") is a method of fast-moving, air-and-land warfare first used extensively during World War II. German armies invading Poland in 1939 used tanks, armored trucks, self-propelled guns, and dive bombers to break through opposing forces and penetrate far behind their lines. During the invasion of the Low Countries and France in 1940, the German armored columns again used these tactics to shock and disorganize the defenders. On the Allied side, U.S. general George S. Patton exhibited (1944) particular skill in mobile warfare in Europe.
Starting out with 45 employees, the company grew to more than 1,700 at its peak in 1944. Initially, Schindler hired Jewish workers because they were a less expensive Polish workforce. But as Nazi atrocities against the Jewish community increased, Schindler’s attitude changed. With the help of Stern, he found reasons to hire more Jewish workers, regardless of their abilities. By 1942, nearly half of his employees were Jewish and were known as Schindlerjuden (Schindler Jews). When the Nazis began to relocate Krakow’s Jews to labor camps, Itzhak Stern and several hundred other employees were among them. Schindler raced to the train station and confronted an SS officer, arguing that his workers were essential to the war effort. After several tense minutes of dropping names and making veiled threats, Schindler was able to free his workers and escort them back to the factory.

Soon after he became chancellor, Hitler called for new elections in an effort to get full control of the Reichstag, the German parliament, for the Nazis. The Nazis used the government apparatus to terrorize the other parties. They arrested their leaders and banned their political meetings. Then, in the midst of the election campaign, on February 27, 1933, the Reichstag building burned. A Dutchman named Marinus van der Lubbe was arrested for the crime, and he swore he had acted alone. Although many suspected the Nazis were ultimately responsible for the act, the Nazis managed to blame the Communists, thus turning more votes their way.
In late 1944, Plaszow and all its sub-camps had to be evacuated in face of the Russian advance. Most of the camp inmates—more than 20,000 men, women, and children—were sent to extermination camps. On receiving the order to evacuate, Schindler, who had approached the appropriate section in the Supreme Command of the Army (OKW), managed to obtain official authorization to continue production in a factory that he and his wife had set up in Brünnlitz, in their native Sudetenland. The entire work force from Zablocie—to which were furtively added many new names from the Plaszow camp—was supposed to move to the new factory site. However, instead of being brought to Brünnlitz, the 800 men—among them 700 Jews—and  the 300 women on Schindler’s list were diverted to Gross-Rosen and to Auschwitz, respectively.

Paradoxically, at the same time that Germany tried to rid itself of its Jews via forced emigration, its territorial expansions kept bringing more Jews under its control. Germany annexed Austria in March 1938 and the Sudetenland (now in the Czech Republic) in September 1938. It established control over the Protectorate of Bohemia and Moravia (now in the Czech Republic) in March 1939. When Germany invaded Poland on September 1, 1939, the “Jewish question” became urgent. When the division of Poland between Germany and the Soviet Union was complete, more than two million more Jews had come under German control. For a time, the Nazis considered shipping the Jews to the island of Madagascar, off the southeast coast of Africa, but discarded the plan as impractical; the Nazis had not prevailed in the Battle of Britain, the seas had become a war zone, and the resources required for such a massive deportation were scarce.
Use of armoured forces was crucial for both sides on the Eastern Front. Operation Barbarossa, the German invasion of the Soviet Union in 1941, involved a number of breakthroughs and encirclements by motorised forces. Its goal according to Führer Directive 21 (18 December 1940) was "to destroy the Russian forces deployed in the West and to prevent their escape into the wide-open spaces of Russia."[90] The Red Army was to be destroyed west of the Dvina and Dnieper rivers, which were about 500 kilometres (310 mi) east of the Soviet border, to be followed by a mopping-up operation. The surprise attack resulted in the near annihilation of the Voyenno-Vozdushnye Sily (VVS, Soviet Air Force) by simultaneous attacks on airfields,[91] allowing the Luftwaffe to achieve total air supremacy over all the battlefields within the first week.[92][93] On the ground, four German panzer groups outflanked and encircled disorganised Red Army units, while the marching infantry completed the encirclements and defeated the trapped forces.[94] In late July, after 2nd Panzer Group (commanded by Guderian) captured the watersheds of the Dvina and Dnieper rivers near Smolensk, the panzers had to defend the encirclement, because the marching infantry divisions were still hundreds of kilometres to the west.[91]
The Auschwitz registry (Hauptbücher) shows that 20,946 Roma were registered prisoners,[145] and another 3,000 are thought to have entered unregistered.[146] On 22 March 1943, one transport of 1,700 Polish Sinti and Roma was gassed on arrival because of illness, as was a second group of 1,035 on 25 May 1943.[145] The SS tried to liquidate the camp on 16 May 1944, but the Roma fought them, armed with knives and iron pipes, and the SS retreated. Shortly after this, the SS removed nearly 2,908 from the family camp to work, and on 2 August 1944 gassed the other 2,897. Ten thousand remain unaccounted for.[147]
For the German rulers, the ghetto was a temporary measure, a holding pen for the Jewish population until a policy on its fate could be established and implemented. For the Jews, ghetto life was the situation under which they thought they would be forced to live until the end of the war. They aimed to make life bearable, even under the most trying circumstances. When the Nazis prohibited schools, they opened clandestine schools. When the Nazis banned religious life, it persisted in hiding. The Jews used humour as a means of defiance, so too song. They resorted to arms only late in the Nazi assault.
The fortified walls, barbed wire, railway sidings, platforms, barracks, gallows, gas chambers and crematoria at Auschwitz Birkenau show clearly how the Holocaust, as well as the Nazi German policy of mass murder and forced labour took place. The collections at the site preserve the evidence of those who were premeditatedly murdered, as well as presenting the systematic mechanism by which this was done. The personal items in the collections are testimony to the lives of the victims before they were brought to the extermination camps, as well as to the cynical use of their possessions and remains. The site and its landscape have high levels of authenticity and integrity since the original evidence has been carefully conserved without any unnecessary restoration.
Blitzkrieg tactics often affected civilians in a way perceived by some to be negative — sometimes intentionally, and sometimes not. Whereas more traditional conflict resulted in a well-defined, slow moving front line, giving civilians time to be evacuated to safety, the new approach did not provide for this luxury. As a result, civilian casualties, as a percentage of the total, increased substantially. Furthermore, in the total war doctrine, civilians were explicitly targeted (as in the Allied bombing of Dresden), in an effort to break the morale of the citizenry of a country in order to frustrate attempts at production, and ultimately support for the cause over which the war was fought.

Known as block 13 until 1941, block 11 of Auschwitz I was the prison within the prison, where violators of the numerous rules were punished. To extract information from them, guards would hold inmates' heads held against the stove, burning their faces and eyes. Some prisoners were made to spend the nights in standing cells. Measuring 1.5 m2 (16 sq ft), the cells held four men who could do nothing but stand, and who were forced the following day to work as usual.[136] In other cells, inmates were subjected to hanging with their hands behind their backs, thus dislocating their shoulder joints. In the basement were the "dark cells", which had only a 5 x 5 cm opening and a solid door. Prisoners placed in these cells gradually suffocated as they ran out of oxygen; sometimes the SS lit a candle in the cell to use up the oxygen more quickly.[137]
The mass killings of Jews in the occupied Soviet territories were assigned to four SS formations called Einsatzgruppen ("task groups"), which were under Heydrich's overall command. Similar formations had been used to a limited extent in Poland in 1939, but the ones operating in the Soviet territories were much larger.[242] The Einsatzgruppen's commanders were ordinary citizens: the great majority were professionals and most were intellectuals.[243] By the winter of 1941–1942, the four Einsatzgruppen and their helpers had killed almost 500,000 people.[244] The largest massacre of Jews by the mobile killing squads in the Soviet Union was at a ravine called Babi Yar outside Kiev,[245] where 33,771 Jews were killed in a single operation on 29–30 September 1941.[246][n] A mixture of SS and Security Police, assisted by Ukrainian police, carried out the killings.[248] Although they did not actively participate in the killings, men of the German 6th Army helped round up the Jews of Kiev and transport them to be shot.[249] By the end of the war, around two million are thought to have been victims of the Einsatzgruppen and their helpers in the local population and the German Army. Of those, about 1.3 million were Jews and up to a quarter of a million Roma.[250]
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.
Auschwitz Birkenau was het grootste concentratie- en vernietigingskamp in het Derde Rijk. De versterkte muren, prikkeldraad, perrons, galg, gaskamers en crematieovens laten de omstandigheden zien waarin de genocide door de nazi’s plaats vond. Volgens historisch onderzoek werden er in dit kamp 1,5 miljoen mensen, systematisch uitgehongerd, gemarteld en vermoord. Hiervan waren er meer dan een miljoen Joods en tienduizenden Pools. Auschwitz diende ook als een kamp voor de raciale moord op duizenden Roma en Sinti. De plaats staat symbool voor de wreedheid die de mens zijn medemens in de 20e eeuw aandeed. Het kamp is een belangrijke plaats ter herinnering aan de Holocaust.
Raphael Lemkin, a holocaust survivor who worked on the Nuremberg Trials, coined the term genocide and spent 4 years pushing for it to be added to international law. As Champetier de Ribes, the French Prosecutor at the Nuremberg Trials explained “This [was] a crime so monstrous, so undreamt of in history throughout the Christian era up to the birth of Hitlerism that the term ‘genocide’ has had to be coined to define it.” Ultimately, in 1948 The United Nations Convention on the Prevention and Punishment of Genocide was adopted, and it entered into force in 1951. The convention defined genocide in legal terms based on Lemkin’s work, and is the basis for genocide prevention efforts today.

Marked by fierce close quarters combat and direct assaults on civilians in air raids, it is often regarded as the single largest (nearly 2.2 million personnel) and bloodiest (1.8–2 million killed, wounded or captured) battle in the history of warfare. It was an extremely costly defeat for German forces, and the Army High Command had to withdraw vast military forces from the West to replace their losses.

On 24 December 1941 the resistance groups representing the various prisoner factions met in block 45 and agreed to cooperate. Fleming writes that it has not been possible to track Pilecki's early intelligence from the camp. Pilecki compiled two reports after he escaped in April 1943; the second, Raport W, detailed his life in Auschwitz I and estimated that 1.5 million people, mostly Jews, had been killed.[203] On 1 July 1942, the Polish Fortnightly Review published a report describing Birkenau, writing that "prisoners call this supplementary camp 'Paradisal', presumably because there is only one road, leading to Paradise". Reporting that inmates were being killed "through excessive work, torture and medical means", it noted the gassing of the Soviet prisoners of war and Polish inmates in Auschwitz I in September 1941, the first gassing in the camp. It said: "It is estimated that the Oswiecim camp can accommodate fifteen thousand prisoners, but as they die on a mass scale there is always room for new arrivals."[204]
The most infamous doctor at Auschwitz was Josef Mengele, the "Angel of Death", who worked in Auschwitz II from 30 May 1943, at first in the gypsy family camp.[127] Particularly interested in performing research on identical twins, dwarfs, and those with hereditary disease, Mengele set up a kindergarten in barracks 29 and 31 for children he was experimenting on, and for all Romani children under six, where they were given better food rations.[128] From May 1944, he would select twins and dwarfs during selection on the Judenrampe,[129] reportedly calling for twins with "Zwillinge heraus!" ("twins step forward!").[130] He and other doctors (the latter prisoners) would measure the twins' body parts, photograph them, and subject them to dental, sight and hearing tests, x-rays, blood tests, surgery, and blood transfusions between them.[131] Then he would have them killed and dissected.[129] Kurt Heissmeyer, another German doctor and SS officer, took 20 Jewish children from Auschwitz to use in pseudoscientific medical experiments at the Neuengamme concentration camp.[132] In April 1945, the children were killed by hanging to conceal the project.[133]
The Soviets found 7,600 inmates in Auschwitz.[385] Some 60,000 prisoners were discovered at Bergen-Belsen by the British 11th Armoured Division;[386] 13,000 corpses lay unburied, and another 10,000 people died from typhus or malnutrition over the following weeks.[387] The BBC's war correspondent, Richard Dimbleby, described the scenes that greeted him and the British Army at Belsen, in a report so graphic the BBC declined to broadcast it for four days, and did so, on 19 April, only after Dimbleby had threatened to resign.[388]
"BLITZKRIEG" or lightning war is not a German term for just any kind of quickly waged and violent war. It is a name for a special kind of quickly waged and violent war which has a technique of its own. The ideas which lie back of this technique began taking shape in Germany in the period after the failure of either the Allies or the Germans to break through on the Western Front during 1915 and 1916, and they matured after the outbreak of the civil war in Spain.
According to the Yad Vashem Holocaust Martyrs' and Heroes' Remembrance Authority in Jerusalem, "[a]ll the serious research" confirms that between five and six million Jews died.[391] Early postwar calculations were 4.2 to 4.5 million from Gerald Reitlinger;[392] 5.1 million from Raul Hilberg; and 5.95 million from Jacob Lestschinsky.[393] In 1986 Lucy S. Dawidowicz used the pre-war census figures to estimate 5.934 million.[394] Yehuda Bauer and Robert Rozett in the Encyclopedia of the Holocaust (1990) estimated 5.59–5.86 million.[395] A 1996 study led by Wolfgang Benz suggested 5.29 to 6.2 million, based on comparing pre- and post-war census records and surviving German documentation on deportations and killings.[391] Martin Gilbert arrived at a minimum of 5.75 million.[396] The figures include over one million children.[397]
After some time off to recover in Zwittau, Schindler was promoted to second in command of his Abwehr unit and relocated with his wife to Ostrava, on the Czech-Polish border, in January 1939.[13] He was involved in espionage in the months leading up to Hitler's seizure of the remainder of Czechoslovakia in March. Emilie helped him with paperwork, processing and hiding secret documents in their apartment for the Abwehr office.[14] As Schindler frequently travelled to Poland on business, he and his 25 agents were in a position to collect information about Polish military activities and railways for the planned invasion of Poland.[15] One assignment called for his unit to monitor and provide information about the railway line and tunnel in the Jablunkov Pass, deemed critical for the movement of German troops.[16] Schindler continued to work for the Abwehr until as late as fall 1940, when he was sent to Turkey to investigate corruption among the Abwehr officers assigned to the German embassy there.[17]
