Uprisings broke out in some extermination camps. The few remaining Jews kept alive to dispose of bodies and sort possessions realised the number of transportees was reducing and they would be next. Civilian uprisings occurred across Poland as mainly young Jews, whose families had already been murdered, began to resist Nazi oppression. With reports of rebellion and mass murder in the British press, the situation in the camps could no longer be be ignored.
Guderian expressed a hearty contempt for General Ludwig Beck, chief of the General Staff from 1935 to 1938, whom he characterized as hostile to ideas of modern mechanised warfare: [Corum quoting Guderian] "He [Beck] was a paralysing element wherever he appeared....[S]ignificantly of his way of thought was his much-boosted method of fighting which he called delaying defence". This is a crude caricature of a highly competent general who authored Army Regulation 300 (Troop Leadership) in 1933, the primary tactical manual of the German Army in World War II, and under whose direction the first three panzer divisions were created in 1935, the largest such force in the world of the time.[153]
Auschwitz-Birkenau was the largest Nazi extermination and concentration camp, located in the Polish town of Oswiecim, 37 miles west of Cracow. One sixth of all Jews murdered by the Nazis were gassed at Auschwitz. In April 1940 SS chief Heinrich Himmler ordered the establishment of a new concentration camp in Oswiecim, a town located within the portion of Poland that was annexed to Germany at the beginning of World War II. The first Polish political prisoners arrived in Auschwitz in June 1940, and by March 1941 there were 10,900 prisoners, the majority of whom were Polish. Auschwitz soon became known as the most brutal of the Nazi concentration camps.
In 1997 a suitcase belonging to Schindler containing historic photographs and documents was discovered in the attic of the apartment of Ami and Heinrich Staehr in Hildesheim. Schindler had stayed with the couple for a few days shortly before his death in 1974. Staehr's son Chris took the suitcase to Stuttgart, where the documents were examined in detail in 1999 by Dr. Wolfgang Borgmann, science editor of the Stuttgarter Zeitung. Borgmann wrote a series of seven articles, which appeared in the paper from 16 to 26 October 1999 and were eventually published in book form as Schindlers Koffer: Berichte aus dem Leben eines Lebensretters ; eine Dokumentation der Stuttgarter Zeitung (Schindler's Suitcase: Report on the Life of a Rescuer). The documents and suitcase were sent to the Holocaust museum at Yad Vashem in Israel for safekeeping in December 1999.[102]
Pogroms occurred in several countries occupied by, or supportive of, Germany, attacks that were both encouraged by the Germans and carried out without their involvement.[225] Thousands of Jews were killed in January and June 1941 in the Bucharest pogrom and Iaşi pogrom in Romania, a German ally.[226] According to a 2004 report written by Tuvia Friling and others, up to 14,850 Jews died during the Iaşi pogrom.[227] The Romanian military killed up to 25,000 Jews in Odessa, then under Romanian control, between 18 October 1941 and March 1942, assisted by gendarmes and the police.[228] Mihai Antonescu, Romania's deputy prime minister, is reported as saying it was "the most favorable moment in our history" to solve the "Jewish problem".[229] In July 1941 he said it was time for "total ethnic purification, for a revision of national life, and for purging our race of all those elements which are foreign to its soul, which have grown like mistletoes and darken our future".[230]
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.

Blitzkrieg sought decisive actions at all times. To this end, the theory of a schwerpunkt (focal point) developed; it was the point of maximum effort. Panzer and Luftwaffe forces were used only at this point of maximum effort whenever possible. By local success at the schwerpunkt, a small force achieved a breakthrough and gained advantages by fighting in the enemy's rear. It is summarized by Guderian as "Nicht kleckern, klotzen!" ("Don't tickle, smash!")

Germany invaded the Soviet Union in June 1941.[236] German propaganda portrayed the war against the Soviet Union as both an ideological war between German National Socialism and Jewish Bolshevism and a racial war between the Germans and the Jewish, Romani and Slavic Untermenschen ("sub-humans").[237] Local populations in some occupied Soviet territories actively participated in the killing of Jews and others, and helped identify and round up Jews.[238] German involvement ranged from active instigation and involvement to general guidance.[239] In Lithuania, Latvia, and western Ukraine, locals were deeply involved in the murder of Jews from the beginning of the German occupation. Some of these Latvian and Lithuanian units also participated in the murder of Jews in Belarus. In the south, Ukrainians killed about 24,000 Jews and some went to Poland to serve as concentration and death-camp guards.[238] Military units from some countries allied to Germany also killed Jews. Romanian units were given orders to exterminate and wipe out Jews in areas they controlled.[240] Ustaše militia in Croatia persecuted and murdered Jews, among others.[168] Many of the killings were carried out in public, a change from previous practice.[241]
Oscar Schindler was all that stood between them and death at the hands of the Nazis. A man all too human, full of flaws like the rest of us. The unlikeliest of all role models - a Nazi, a womanisor, a war profiteer. An ordinary man who answered the call of conscience. Even in the worst of circumstances Oscar Schindler did extraordinary things, matched by no one. He remained true to his Jews, the workers he referred to as my children. He kept the SS out and everyone alive.
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.
Tens of thousands of prisoners, mostly Jews, were forced to march either northwest for 55 kilometers (approximately 30 miles) to Gliwice (Gleiwitz) or due west for 63 kilometers (approximately 35 miles) to Wodzislaw (Loslau) in the western part of Upper Silesia. Those forced to march northwest were joined by prisoners from subcamps in East Upper Silesia, such as Bismarckhuette, Althammer, and Hindenburg. Those forced to march due west were joined by inmates from the subcamps to the south of Auschwitz, such as Jawischowitz, Tschechowitz, and Golleschau.

Around one in six Jews killed in the Holocaust died in Auschwitz.[195] By nation, the greatest number of Auschwitz's Jewish victims originated from Hungary, accounting for 430,000 deaths, followed by Poland (300,000), France (69,000), Netherlands (60,000), Greece (55,000), Protectorate of Bohemia and Moravia (46,000), other camps (34,000), Slovakia (27,000), Belgium (25,000), Germany and Austria (23,000), Yugoslavia (10,000), Italy (7,500), and Norway (690).[6] Fewer than one percent of Soviet Jews murdered in the Holocaust were killed in Auschwitz; German forces had already been driven from Russia when the killing at Auschwitz reached its peak in 1944.[196] Of the 400 Jehovah's Witnesses who were imprisoned at Auschwitz, 132 died there.[197]
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.

Lunch was three quarters of a liter of watery soup at midday, reportedly foul-tasting, with meat in the soup four times a week and vegetables (mostly potatoes and rutabaga) three times. The evening meal was 300 grams of bread, often moldy, part of which the inmates were expected to keep for breakfast the next day, with a tablespoon of cheese or marmalade, or 25 grams of margarine or sausage. Prisoners engaged in hard labor were given extra rations.[114]

This is the punishment card of a prisoner in Auschwitz-Birkenau, dated 24 October 1942. In German it reads: “Trotz verbot hinter haus 7 seine Grossnotdurft verrichtete”. In English this means: “Despite being forbidden, the prisoner went behind block 7 to relieve themselves”. The prisoner would have been severely punished for going to the toilet without permission as a warning to other prisoners.

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.

In the fall of that year the Płaszów work camp opened nearby, and by February 1943 it was under the command of the notoriously sadistic SS officer Amon Göth, who would be executed after the war. Capitalizing on the officer’s appetite for drink and other luxury items available mainly on the black market, Schindler cultivated his friendship by ensuring a constant stream of them to the villa from which he oversaw the camp. Schindler thus managed to prevail upon Göth to create a separate camp for his Jewish workers, where they were free of the abuses suffered at Płaszów. Though Schindler’s motivations prior to this point are unclear, many scholars interpret his efforts to extricate his workers from Płaszów as indication that his concern for them was not purely financial.
Schindler's ties with the Abwehr and his connections in the Wehrmacht and its Armaments Inspectorate enabled him to obtain contracts to produce enamel cookware for the military.[31] These connections also later helped him protect his Jewish workers from deportation and death.[32] As time went on, Schindler had to give Nazi officials ever larger bribes and gifts of luxury items obtainable only on the black market to keep his workers safe.[33] Bankier, a key black market connection, obtained goods for bribes as well as extra materials for use in the factory.[34] Schindler himself enjoyed a lavish lifestyle and pursued extramarital relationships with his secretary, Viktoria Klonowska, and Eva Kisch Scheuer, a merchant specialising in enamelware from DEF.[35] Emilie Schindler visited for a few months in 1940 and moved to Kraków to live with Oskar in 1941.[36][37]
