These techniques were used to great effect in 1939, when the Polish Army was destroyed in a series of encirclement battles. In May 1940 Hitler attacked France, his panzer divisions smashing through slow-moving French formations and cutting off the British Expeditionary Force at Dunkirk. Spectacular success was also achieved during the invasion of the Soviet Union in 1941 and large numbers of Soviet troops were captured.
Medical experiments conducted on camp inmates by the SS were another distinctive feature.[51] At least 7,000 prisoners were subjected to experiments; most died as a result, during the experiments or later.[52] Twenty-three senior physicians and other medical personnel were charged at Nuremberg, after the war, with crimes against humanity. They included the head of the German Red Cross, tenured professors, clinic directors, and biomedical researchers.[53] Experiments took place at Auschwitz, Buchenwald, Dachau, Natzweiler-Struthof, Neuengamme, Ravensbrück, Sachsenhausen, and elsewhere. Some dealt with sterilization of men and women, the treatment of war wounds, ways to counteract chemical weapons, research into new vaccines and drugs, and the survival of harsh conditions.[52]
Auschwitz was the Nazis' largest concentration and extermination camp. It was founded on Himmler's orders on the 27th of April 1940, close to the small Polish town of Oświęcim. The first inmates - mostly Polish political prisoners - were brought there in June 1940 and were used for slave labour. By March 1941, more than 10 000 prisoners were registered here. The Auschwitz camp was renowned for its harshness, with the most infamous being Block 11 (known as the bunker), where prisoners received the cruellest punishments. In front of it stood the „black wall“, the site of frequent executions. The inscription „Arbeit macht frei!“ above the main gate of the original camp at Auschwitz was merely a cynical mockery.
On June 6, 1944, also known as D-Day, more than 150,000 Allied soldiers landed in France. In December the Germans started an unsuccessful counterattack in Belgium and northern France, known as the Battle of the Bulge. Continuing to gain momentum, the Soviets began an offensive in January 1945, liberating western Poland and then forcing Hungary to surrender.
The first official orchestra to be set up in Birkenau was in the men’s camp in August 1942, when a group of sixteen musicians was brought in from the main Auschwitz orchestra.  Unlike in Auschwitz, in Birkenau Jews were allowed to join.  The first conductor was the Polish prisoner Jan Zaborski, who was replaced a few months later by Franz Kopka.  Of this early period in the orchestra's existence, the Polish-Jewish violinist Szymon Laks recalled that those who could,
As Soviet armies advanced in 1944 and early 1945, Auschwitz was gradually abandoned. On January 18, 1945, some 60,000 prisoners were marched to Wodzisław Śląski, where they were put on freight trains (many in open cars) and sent westward to concentration camps away from the front. One in four died en route from starvation, cold, exhaustion, and despair. Many were shot along the way in what became known as the “death marches.” The 7,650 sick or starving prisoners who remained were found by arriving Soviet troops on January 27, 1945.
The traditional meaning of blitzkrieg is that of German tactical and operational methodology in the first half of the Second World War, that is often hailed as a new method of warfare. The word, meaning "lightning war" or "lightning attack" in its strategic sense describes a series of quick and decisive short battles to deliver a knockout blow to an enemy state before it could fully mobilize. Tactically, blitzkrieg is a coordinated military effort by tanks, motorized infantry, artillery and aircraft, to create an overwhelming local superiority in combat power, to defeat the opponent and break through its defences.[16][17] Blitzkrieg as used by Germany had considerable psychological, or "terror" elements,[c] such as the Jericho Trompete, a noise-making siren on the Junkers Ju 87 dive-bomber, to affect the morale of enemy forces.[d] The devices were largely removed when the enemy became used to the noise after the Battle of France in 1940 and instead bombs sometimes had whistles attached.[18][19] It is also common for historians and writers to include psychological warfare by using Fifth columnists to spread rumours and lies among the civilian population in the theatre of operations.[16]
Despite the continuing war with Great Britain, German forces invaded the Soviet Union in June 1941. At first, the German Blitzkrieg seemed to succeed. Soviet forces were driven back more than 600 miles to the gates of Moscow, with staggering losses. In December 1941, Hitler unilaterally declared war on the United States, which consequently added its tremendous economic and military power to the coalition arrayed against him. A second German offensive against the Soviet Union in 1942 brought German forces in the east to the shores of the Volga River and the city of Stalingrad. However, the Soviet Union launched a counteroffensive in November 1942, trapping and destroying an entire German army at Stalingrad.
By the spring of 1942, the Nazis had established six killing centers (death camps) in Poland: Chelmno (Kulmhof), Belzec, Sobibor, Treblinka, Maidanek and Auschwitz. All were located near railway lines so that Jews could be easily transported daily. A vast system of camps (called Lagersystem) supported the death camps. The purpose of these camps varied: some were slave labor camps, some transit camps, others concentration camps and their sub­camps, and still others the notorious death camps. Some camps combined all of these functions or a few of them. All the camps were intolerably brutal.
Like the network of concentration camps that followed, becoming the killing grounds of the Holocaust, Dachau was under the control of Heinrich Himmler, head of the elite Nazi guard, the Schutzstaffel (SS), and later chief of the German police. By July 1933, German concentration camps (Konzentrationslager in German, or KZ) held some 27,000 people in “protective custody.” Huge Nazi rallies and symbolic acts such as the public burning of books by Jews, Communists, liberals and foreigners helped drive home the desired message of party strength.
Some Germans, even some Nazis, dissented from the murder of the Jews and came to their aid. The most famous was Oskar Schindler, a Nazi businessman, who had set up operations using involuntary labour in German-occupied Poland in order to profit from the war. Eventually, he moved to protect his Jewish workers from deportation to extermination camps. In all occupied countries, there were individuals who came to the rescue of Jews, offering a place to hide, some food, or shelter for days or weeks or even for the duration of the war. Most of the rescuers did not see their actions as heroic but felt bound to the Jews by a common sense of humanity. Israel later recognized rescuers with honorary citizenship and commemoration at Yad Vashem, Israel’s memorial to the Holocaust.

The enormous might of Hitler’s Wehrmacht in 1941 lay in the quality of its personnel, its optimized organizational decisions (regarding operations in tank groups, air fleets and other formations), its top-notch operational art and tactics and in the fact that many of its weapons systems and military technologies were well matched to the blitzkrieg’s objectives.

^ These are some of the many notable historians that have casually used the term blitzkrieg—including some who have written on its misconception—to describe several Wehrmacht military operations that were spearheaded by a dense concentration of armoured and motorised formations with the aim of delivering a breakthrough, and exploiting it with speed to paralyse and encircle the enemy: David Glantz (Glantz 2010, p. 14; Glantz 2009, p. 164; Glantz 2001), Jonathan House (Glantz & House 1999, pp. 254, 269; Glantz & House 1995, pp. 61, 125, 167, 226, 274, 286, 288), Lloyd Clark (Clark 2012, pp. 22–27, 187), Antony Beevor (Beevor 1999, pp. 13, 148; Beevor 2006, p. 157), Mungo Melvin (Melvin 2011, pp. 46, 79–80, 199), John Erickson (Erickson 2001, pp. 558, 567) and Steven Mercatante (Mercatante 2012, pp. 65, 77, 91, 301).

Oskar Schindler renamed the factory Deutsche Emaillewaren-Fabrik (German Enamelware Factory) and started production with a small staff. Possessing a certain panache for business and engaging in influence peddling, Schindler secured numerous German army contracts for kitchenware. He soon met Itzhak Stern, a Jewish accountant, who connected Schindler with Krakow’s Jewish community to staff the factory.
On 19 November 1942, the Red Army launched Operation Uranus, a two-pronged attack targeting the weaker Romanian and Hungarian armies protecting the German 6th Army's flanks. The Axis forces on the flanks were overrun and the 6th Army was cut off and surrounded in the Stalingrad area. Adolf Hitler ordered that the army stay in Stalingrad and make no attempt to break out; instead, attempts were made to supply the army by air and to break the encirclement from the outside. Heavy fighting continued for another two months. By the beginning of February 1943, the Axis forces in Stalingrad had exhausted their ammunition and food. The remaining units of the 6th Army surrendered. The battle lasted five months, one week and three days. Show less

Initially, Schindler was mostly interested in the money-making potential of the business and hired Jews because they were cheaper than Poles—the wages were set by the occupying Nazi regime.[38] Later he began shielding his workers without regard for cost.[39] The status of his factory as a business essential to the war effort became a decisive factor enabling him to help his Jewish workers. Whenever Schindlerjuden (Schindler Jews) were threatened with deportation, he claimed exemptions for them. He claimed wives, children, and even people with disabilities were necessary mechanics and metalworkers.[39] On one occasion, the Gestapo came to Schindler demanding that he hand over a family that possessed forged identity papers. "Three hours after they walked in," Schindler said, "two drunk Gestapo men reeled out of my office without their prisoners and without the incriminating documents they had demanded."[40]
