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
I visited in 1991 with a bus full of young people partying around Europe. When we got back on the bus - there was silence and sobbing for an hour or more as we drove off to our next destination. It is a traumatic experience seeing the depths of evil that mankind can descend to - every human should see this place and think twice about how you treat your fellow man. The sheer scale of the place is amazing -I am so lucky to live in a free multicultural country where racial discrimination is not tolerated and where we learn history about the rest of the world - not just our own. But nothing can prepare you for the horrors of this place - it makes you wonder how such hatred can infest the mind and you can then treat fellow humans - including children and babies - as less than animals like stamping on ants. Here I am writing about it 20 years later when out of interest I was browsing the subject on the internet and came across this site - and it saddens me that ignorant people who havent been there can make some of the disgusting comments that are on this page.
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.
The vital industries and transportation centers that would be targeted for shutdown were valid military targets. Civilians were not to be targeted directly, but the breakdown of production would affect their morale and will to fight. German legal scholars of the 1930s carefully worked out guidelines for what type of bombing was permissible under international law. While direct attacks against civilians were ruled out as "terror bombing", the concept of the attacking the vital war industries – and probable heavy civilian casualties and breakdown of civilian morale – was ruled as acceptable.[138]
Later manifestations of blitzkrieg tactics were the combined air and ground attacks by Israeli forces on Syria and Egypt during the Six-Day War (June 1967) and the Israeli counterattacks and final counteroffensive of the Yom Kippur War (October 1973). The “left hook” flanking maneuver executed by U.S. Gen. Norman Schwarzkopf during the Persian Gulf War also utilized elements of blitzkrieg tactics, with a combined arms offensive that destroyed the Iraqi army in Kuwait in a period of just three days.
Auschwitz-Birkenau was also a killing center and played a central role in the German effort to kill the Jews of Europe. Around the beginning of September, 1941, the SS at Auschwitz I conducted the first tests of Zyklon B as a mass murder agent, using Soviet POWs and debilitated Polish prisoners as victims. The “success” of these experiments led to the construction of a chamber in the crematorium of Auschwitz I that, like the subsequent gas chambers at Auschwitz, used Zyklon B to murder victims. The first transports of Jewish men, women, and children sent to Auschwitz as part of the “final solution” were murdered in this gas chamber (Crematorium I) in February and March 1942.
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.
Central to this is the decision cycle. Every decision made by German or opposing forces required time to gather information, make a decision, disseminate orders to subordinates, and then implement this decision through action. Through superior mobility and faster decision-making cycles, mobile forces could take action on a situation sooner than the forces opposing them.

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.
Several SS personnel oversaw the killings at each gas chamber, while the bulk of the work was done by the mostly Jewish prisoners known as Sonderkommandos (special squads).[91][92] Hungarian doctor Miklós Nyiszli reported that the Sonderkommando numbered around 860 prisoners when the Hungarian Jews were being killed in May–July 1944.[93] Their responsibilities included removing goods and corpses from the incoming trains, guiding victims to the dressing rooms and gas chambers, and working in the "Canada" barracks, where the victims' possessions were stored.[94] Housed separately from other prisoners, in somewhat better conditions, their quality of life was further improved by access to the goods taken from murdered prisoners, which they were sometimes able to steal and trade on Auschwitz's black market.[95] Many Sonderkommandos committed suicide in response to the horrors of their work; others were generally shot by the SS in a matter of weeks. New Sonderkommando units were formed from incoming transports. Almost none of the 2,000 prisoners placed in these units survived to the camp's liberation.[96]
As was the case in other camps, the primary form of voluntary music-making in Birkenau was singing.  Due to its size and international composition, there were inmates from all over Europe whose voices survivors remembered.  Prisoners sang to comfort one another, to build solidarity and to express resistance.  The former inmate Kitty Hart remembered that
The German view of the Roma as hereditary criminals and "asocials" was reflected in their classification in the concentration camps, where they were usually counted among the asocials and given black triangles to wear.[420] According to Niewyk and Nicosia, at least 130,000 died out of nearly one million in German-occupied Europe.[415] The United States Holocaust Memorial Museum calculates at least 220,000.[421] Ian Hancock, who specializes in Romani history and culture, argues for between 500,000 and 1,500,000.[422] The treatment of the Roma was not consistent across German-occupied territories. Those in France and the Low Countries were subject to restrictions on movement and some confinement to collection camps, while those in Central and Eastern Europe were sent to concentration camps and murdered by soldiers and execution squads.[423] Before being sent to the camps, the Roma were herded into ghettos, including several hundred into the Warsaw Ghetto.[219] Further east, teams of Einsatzgruppen tracked down Romani encampments and murdered the inhabitants on the spot, leaving no records of the victims.[423] After the Germans occupied Hungary, 1,000 Roma were deported to Auschwitz.[424][x]

Allied air superiority became a significant hindrance to German operations during the later years of the war. By June 1944 the Western Allies had complete control of the air over the battlefield and their fighter-bomber aircraft were very effective at attacking ground forces. On D-Day the Allies flew 14,500 sorties over the battlefield area alone, not including sorties flown over north-western Europe. Against this on 6 June the Luftwaffe flew some 300 sorties. Though German fighter presence over Normandy increased over the next days and weeks, it never approached the numbers the Allies commanded. Fighter-bomber attacks on German formations made movement during daylight almost impossible. Subsequently, shortages soon developed in food, fuel and ammunition, severely hampering the German defenders. German vehicle crews and even flak units experienced great difficulty moving during daylight.[g] Indeed, the final German offensive operation in the west, Operation Wacht am Rhein, was planned to take place during poor weather to minimize interference by Allied aircraft. Under these conditions it was difficult for German commanders to employ the "armoured idea", if at all.[citation needed]
The Nazis regarded the Slavs as subhuman, or Untermenschen.[426] In a secret memorandum dated 25 May 1940, Himmler stated that it was in German interests to foster divisions between the ethnic groups in the East. He wanted to restrict non-Germans in the conquered territories to schools that would only teach them how to write their own name, count up to 500, and obey Germans.[427][y] In November 1939 German planners called for "the complete destruction" of all Poles[430] and resettlement of the land by German colonists.[431] The Polish political leadership was the target of a campaign of murder (Intelligenzaktion and AB-Aktion).[432] Between 1.8 and 1.9 million non-Jewish Polish citizens perished at German hands during the course of the war; about four-fifths were ethnic Poles and the rest Ukrainians and Belarusians.[410] At least 200,000 died in concentration camps, around 146,000 in Auschwitz. Others died in massacres or in uprisings such as the Warsaw Uprising, where 120,000–200,000 were killed.[433] During the occupation, the Germans adopted a policy of restricting food and medical services, as well as degrading sanitation and public hygiene.[434] The death rate rose from 13 per 1000 before the war to 18 per 1000 during the war.[435] Around 6 million of World War II victims were Polish citizens; half the death toll were Jews.[436] Over the course of the war Poland lost 20 percent of its pre-war population.[436] Over 90 percent of the death toll came through non-military losses, through various deliberate actions by Germany and the Soviet Union.[433] Polish children were also kidnapped by Germans to be "Germanized", with perhaps as many as 200,000 children stolen from their families.[437]
Schindler first arrived in Kraków in October 1939, on Abwehr business, and took an apartment the following month. Emilie maintained the apartment in Ostrava and visited Oskar in Kraków at least once a week.[18][19] In November 1939, he contacted interior decorator Mila Pfefferberg to decorate his new apartment. Her son, Leopold "Poldek" Pfefferberg, soon became one of his contacts for black market trading. They eventually became lifelong friends.[20]
