Remarkably, there were instances of individual resistance and collective efforts at fighting back inside Auschwitz. Poles, Communists and other national groups established networks in the main camp. Some Jews assaulted Nazi guards, even at the entrance to the gas chambers. In October 1944, the Sonderkommando crew at crematoria IV revolted and destroyed the crematoria. It was never used again.
The Germans' overwhelming repression and the presence of many collaborators in the various local populations severely limited the ability of the Jews to resist. Jewish resistance did occur, however, in several forms. Staying alive, clean, and observing Jewish religious traditions constituted resistance under the dehumanizing conditions imposed by the Nazis. Other forms of resistance involved escape attempts from the ghettos and camps. Many who succeeded in escaping the ghettos lived in the forests and mountains in family camps and in fighting partisan units. Once free, though, the Jews had to contend with local residents and partisan groups who were often openly hostile. Jews also staged armed revolts in the ghettos of Vilna, Bialystok, Bedzin-Sosnowiec, krakow, and Warsaw.
Reality is at once more limited and more complex. On one level, mobile warfare was a faute de mieux improvisation that arose from the restrictions on conventional forces stipulated by the Treaty of Versailles. The German high command in the 1920s and 1930s also sought inspiration for the future in its own past–specifically in the ideas of Helmuth Karl von Moltke and Alfred von Schlieffen. Tanks, aircraft, and motor trucks were regarded as force multipliers facilitating traditional operational approaches. The aim of German military planners in both the Weimar Republic and the Third Reich was to achieve victory by enveloping enemy armies, threatening their lines of supply and communications, and forcing them to fight in an unexpected direction. The anticipated result would be quick, decisive victories for a state that since the days of Frederick the Great had been convinced of its inability to win a drawn-out war of attrition.
Transportation between camps was often carried out in freight cars with prisoners packed tightly. Long delays would take place; prisoners might be confined in the cars on sidings for days.[190] In mid-1942 work camps began requiring newly arrived prisoners to be placed in quarantine for four weeks.[191] Prisoners wore colored triangles on their uniforms, the color of the triangle denoting the reason for their incarceration. Red signified a political prisoner, Jehovah's Witnesses had purple triangles, "asocials" and criminals wore black and green. Badges were pink for gay men and yellow for Jews.[192] Jews had a second yellow triangle worn with their original triangle, the two forming a six-pointed star.[193][194] In Auschwitz, prisoners were tattooed with an identification number on arrival.[195]
Guderian argued that the tank was the decisive weapon of war. "If the tanks succeed, then victory follows", he wrote. In an article addressed to critics of tank warfare, he wrote "until our critics can produce some new and better method of making a successful land attack other than self-massacre, we shall continue to maintain our beliefs that tanks—properly employed, needless to say—are today the best means available for land attack." Addressing the faster rate at which defenders could reinforce an area than attackers could penetrate it during the First World War, Guderian wrote that "since reserve forces will now be motorized, the building up of new defensive fronts is easier than it used to be; the chances of an offensive based on the timetable of artillery and infantry co-operation are, as a result, even slighter today than they were in the last war." He continued, "We believe that by attacking with tanks we can achieve a higher rate of movement than has been hitherto obtainable, and—what is perhaps even more important—that we can keep moving once a breakthrough has been made." Guderian additionally required that tactical radios be widely used to facilitate co-ordination and command.

In the summer of 1942, when Germany launched another offensive in the southern USSR against Stalingrad and the Caucasus, the Soviets again lost tremendous amounts of territory, only to counter-attack once more during winter. German gains were ultimately limited by Hitler diverting forces from the attack on Stalingrad itself and seeking to pursue a drive to the Caucasus oilfields simultaneously as opposed to subsequently as the original plan had envisaged.

On 27 January 1945, the 60th Army of the First Ukrainian Front, a unit of the Soviet Army, opened the gates and entered the Auschwitz camp complex. The liberators discovered around 7,000 surviving prisoners across the three main camps of Auschwitz I, Auschwitz-Birkenau and Buna Monowitz. Amongst the survivors were 180 children; 52 of them under the age of eight.
There's a basic cafe and cafeteria in the main visitors' centre of Auschwitz I and a coffee machine in the bookshop at Birkenau. More options are in a commercial complex across the street from Auschwitz I, although the quality of one (the Art Hamburger) is rather poor, but a cheap and quick eat. There are hot dog stalls and similar outlets outside the main museum at the end of the bus/car park, with food and drink combinations costing 10-12 zł. The car park outside Auschwitz I also has picnic tables for visitors.
As you walk about the camp it is not difficult to picture the squalor and anguish that victims had to endure. The living accommodation tended to be built like makeshift barns. There were no foundations, and little defense against the elements. Unsurprisingly, inmates were plagued by ill-health - the bitterness of the Polish winter must have been unbearable.
Birkenau (Auschwitz II) was established in October 1941, three kilometers from Auschwitz. Exterminations in Birkenau began in March 1942. There were four gas chambers in the camp that used Zyklon B gas. Until November 1944 the camp functioned as a factory for mass murder, receiving transports from all over Europe. Most of those brought to the camp were Jews and nearly all were immediately sent to the gas chambers. Only a small percentage was selected for labor in the camp itself, labor in munitions plants at satellite camps, or the “medical” experiments of Dr. Josef Mengele and his staff. In the spring and summer of 1944, the rate of extermination was increased as the Jews of Hungary and the Lodz ghetto were brought to the camp.
While some of the guiding conceptions of the Blitzkrieg were tried out in Ethiopia, the results were not considered conclusive. The Ethiopians were a semi-savage people, and they lacked the modern armament and equipment necessary to offer the Italian invaders the kind of resistance essential if Blitzkrieg were to receive a real and complete battlefield test. But Spain furnished a fine proving ground. Then Albania was a dress rehearsal. And in Poland the system was put to the final proof.
The Germans conquered large areas of the Soviet Union but their failure to destroy the Red Army before the winter of 1941 was a strategic failure that made German tactical superiority and territorial gains irrelevant.[95] The Red Army had survived enormous losses and regrouped with new formations far to the rear of the front line. During the Battle of Moscow, the Red Army defeated the German Army Group Center and for the first time in the war seized the strategic initiative.[95][96]
When Soviet troops liberated Auschwitz on January 27, 1945, they found these pitiful survivors as well as 836,525 items of women clothing, 348,820 items of men clothing, 43,525 pairs of shoes and vast numbers of toothbrushes, glasses and other personal effects. They found also 460 artificial limbs and seven tons of human hair shaved from Jews before they were murdered. The human hairs were used by the company "Alex Zink" (located in Bavaria) for confection of cloth. This company was paying the human hairs 50 pfennig/kilo.

But the personalities and characteristics of human beings cannot be spliced. Sometimes character flaws, such as hubris, also lead to great achievements through a willingness to attempt something most people never would. Oskar’s espionage activities on behalf of Germany, while regrettable to enemies of Germany, later put him in a position to save many lives.
Allied air superiority became a significant hindrance to German operations during the later years of the war. Early German successes enjoyed air superiority with unencumbered movement of ground forces, close air support, and aerial reconnaissance. However, the Western Allies' air-to-ground aircraft were so greatly feared out of proportion to their actual tactical success, that following the lead up to Operation Overlord German vehicle crews showed reluctance to move en masse during daylight. Indeed, the final German blitzkrieg operation in the west, Operation Wacht am Rhein, was planned to take place during poor weather which grounded Allied aircraft. Under these conditions, it was difficult for German commanders to employ the "armoured idea" to its envisioned potential.

Known as Kristallnacht (or "Night of Broken Glass"), the attacks were partly carried out by the SS and SA,[122] but ordinary Germans joined in; in some areas, the violence began before the SS or SA arrived.[123] Over 7,500 Jewish shops (out of 9,000) were looted and attacked, and over 1,000 synagogues damaged or destroyed. Groups of Jews were forced by the crowd to watch their synagogues burn; in Bensheim they were forced to dance around it, and in Laupheim to kneel before it.[124] At least 90 Jews died. The damage was estimated at 39 million Reichmarks.[125] Cesarani writes that "[t]he extent of the desolation stunned the population and rocked the regime."[120] Thirty-thousand Jews were sent to the Dachau, Buchenwald and Sachsenhausen concentration camps.[126] Many were released within weeks; by early 1939, 2,000 remained in the camps.[127] German Jewry was held collectively responsible for restitution of the damage; they also had to pay an "atonement tax" of over a billion Reichmarks. Insurance payments for damage to their property were confiscated by the government. A decree on 12 November 1938 barred Jews from most of the remaining occupations they had been allowed to hold.[128] Kristallnacht marked the end of any sort of public Jewish activity and culture, and Jews stepped up their efforts to leave the country.[129]
Whilst carrying out this final evacuation the SS had set about removing evidence of their crimes. Many thousands of documents were set alight. Between 21 and 26 January 1945, the Germans blew up  and partially dismantled the gas chambers and crematoria in Birkenau. Kanada II, the warehouse in which property plundered from victims of the gas chambers was stored and sorted, was also looted and set alight. Members of the Wehrmacht joined in the looting.
While concentration camps were meant to work and starve prisoners to death, extermination camps (also known as death camps) were built for the sole purpose of killing large groups of people quickly and efficiently. The Nazis built six extermination camps, all in Poland: Chelmno, Belzec, Sobibor, Treblinka, Auschwitz, and Majdanek. (Auschwitz and Majdanek were both concentration and extermination camps.)

Oscar Schindler rose to the highest level of humanity, walked through the bloody mud of the Holocaust without soiling his soul, his compassion, his respect for human life -  and gave his Jews a second chance at life. He miraculously managed to do it and pulled it off by using the very same talents that made him a war profiteer - his flair for presentation, bribery, and grand gestures.

Schindler joined the separatist Sudeten German Party in 1935.[6] Although he was a citizen of Czechoslovakia, Schindler became a spy for the Abwehr, the military intelligence service of Nazi Germany, in 1936. He was assigned to Abwehrstelle II Commando VIII, based in Breslau.[7] He later told Czech police that he did it because he needed the money; by this time Schindler had a drinking problem and was chronically in debt.[8]
