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.
The Allied offensive in central France, spearheaded by armored units from George S. Patton's Third Army, used breakthrough and penetration techniques that were essentially identical to Guderian's prewar "armoured idea." Patton acknowledged that he had read both Guderian and Rommel before the war, and his tactics shared the traditional cavalry emphasis on speed and attack. A phrase commonly used in his units was "haul ass and bypass."

Some prisoners—usually Aryan—were assigned positions of authority, such as Blockschreiber ("block clerk"), Funktionshäftling ("functionary"), Kapo ("head" or "overseer"), and Stubendienst ("barracks orderly"). They were considered members of the camp elite, and had better food and lodgings than the other prisoners. The Kapos in particular wielded tremendous power over other prisoners, whom they often abused.[88][89] Very few Kapos were prosecuted after the war, because of the difficulty in determining which Kapo atrocities had been performed under SS orders and which had been individual actions.[90]

The resistance sent out the first oral message about Auschwitz with Dr. Aleksander Wielkopolski, a Polish engineer who was released in October 1940.[201] The following month the Polish underground in Warsaw prepared a report on the basis of that information, The camp in Auschwitz, part of which was published in London in May 1941 in a booklet, The German Occupation of Poland, by the Polish Ministry of Foreign Affairs. The report said of the Jews in the camp that "scarcely any of them came out alive". According to Fleming, the booklet was "widely circulated amongst British officials". The Polish Fortnightly Review based a story on it, writing that "three crematorium furnaces were insufficient to cope with the bodies being cremated", as did The Scotsman on 8 January 1942, the only British news organization to do so.[202]
The French battery now opened rapid fire on our wood and at any moment we could expect their fire to be aimed at our tank, which was in full view. I therefore decided to abandon it as fast as I could, taking the crew with me. At that moment the subaltern in command of the tanks escorting the infantry reported himself wounded, with the words: 'Herr General, my left arm has been shot off.' We clamored up through the sandy pit, shells crashing and splintering all round. Close in front of us trundled Rothenburg's tank with flames pouring out of the rear. The adjutant of the Panzer Regiment had also left his tank. I thought at first that the command tank had been set alight by a hit in petrol tank and was extremely worried for Colonel Rothenbttrg's safety. However, it turned out to be only the smoke candles that had caught light, the smoke from which now served us very well. In the meantime Lieutenant Most had driven my armored signals vehicle into the wood, where it had been hit in the engine and now stood immobilized. The crew was unhurt."
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.
Similarly, in Ordinary Men (1992), Christopher Browning examined the deeds of German Reserve Police Battalion 101 of the Ordnungspolizei ("order police"), used to commit massacres and round-ups of Jews, as well as mass deportations to the death camps. The members of the battalion were middle-aged men of working-class background from Hamburg, who were too old for regular military duty. They were given no special training. During the murder of 1,500 Jews from Józefów in Poland, their commander allowed them to opt out of direct participation. Fewer than 12 men out of a battalion of 500 did so. Influenced by the Milgram experiment on obedience, Browning argued that the men killed out of peer pressure, not bloodlust.[471]
Tested by the Germans during the Spanish Civil War in 1938 and against Poland in 1939, the blitzkrieg proved to be a formidable combination of land and air action. Germany’s success with the tactic at the beginning of World War II hinged largely on the fact that it was the only country that had effectively linked its combined forces with radio communications. The use of mobility, shock, and locally concentrated firepower in a skillfully coordinated attack paralyzed an adversary’s capacity to organize defenses, rather than attempting to physically overcome them, and then exploited that paralysis by penetrating to the adversary’s rear areas and disrupting its whole system of communications and administration. The tactics, as employed by the Germans, consisted of a splitting thrust on a narrow front by combat groups using tanks, dive bombers, and motorized artillery to disrupt the main enemy battle position at the Schwerpunkt. Wide sweeps by armoured vehicles followed, establishing the Kessel that trapped and immobilized enemy forces. Those tactics were remarkably economical of both lives and matériel, primarily for the attackers but also, because of the speed and short duration of the campaign, among the victims.

Blitzkrieg's unique and completely flexible campaign structure puts you in control of deciding how your forces will fare in each of the major engagements that comprise three central Campaigns. Hardcore vets have the option of engaging the enemy immediately in a desperate struggle for battlefield dominance, or more cautious players can choose from pre-defined or unlimited randomly generated side missions as they gain experience, promotions and weapons upgrades as well as wear down the enemy before the central conflict.

As the war progressed, Allied armies began using combined arms formations and deep penetration strategies that Germany had attempted to use in the opening years of the war. Many Allied operations in the Western Desert and on the Eastern Front relied on massive concentrations of firepower to establish breakthroughs by fast-moving armoured units. These artillery-based tactics were also decisive in Western Front operations after Operation Overlord and both the British Commonwealth and American armies developed flexible and powerful systems for utilizing artillery support. What the Soviets lacked in flexibility, they made up for in number of multiple rocket launchers, cannon and mortar tubes. The Germans never achieved the kind of response times or fire concentrations their enemies were capable of by 1944.

Also that November, Schindler was introduced to Itzhak Stern, an accountant for Schindler's fellow Abwehr agent Josef "Sepp" Aue, who had taken over Stern's formerly Jewish-owned place of employment as a Treuhander (trustee).[21] Property belonging to Polish Jews, including their possessions, places of business, and homes were seized by the Germans beginning immediately after the invasion, and Jewish citizens were stripped of their civil rights.[22] Schindler showed Stern the balance sheet of a company he was thinking of acquiring, an enamelware factory called Rekord Ltd[a] owned by a consortium of Jewish businessmen that had filed for bankruptcy earlier that year.[23] Stern advised him that rather than running the company as a trusteeship under the auspices of the Haupttreuhandstelle Ost (Main Trustee Office for the East), he should buy or lease the business, as that would give him more freedom from the dictates of the Nazis, including the freedom to hire more Jews.[24]
