In order to protect the tanks, and secure the areas penetrated by the German army, motorized infantry would accompany tanks into battle. The Germans believed the only way to defeat an enemy force was to cut it off. Cutting it off required superior mobility relative to the enemy force. The introduction of mechanical means on the battlefield provided the Germans the answer to the deadlocks common in WWI. Tanks and other armored vehicles gave the German Army the ability to force the enemy to react to their new found mobility.

You can visit the site on your own (highly recommended because you can go at your own pace, see what you want to see and have a much more meaningful experience) if you arrive before the guided tours start. Another option is to visit the Auschwitz II-Birkenau site first and then return after the guided tours finish to the first camp to avoid having to use the tour. The Auschwitz II-Birkenau site is open for visitors without the guide during the opening hours of the Memorial.

The Maginot Line: the Allies expected a protracted, defensive war  © Across the English Channel, a stunned British military establishment struggled to determine how it was that events had so quickly gone so horribly wrong. The BEF had sailed for France believing that they and their French ally were well equipped and well trained to fight a modern war. In truth, as events proved, they were completely unprepared to face Hitler's Wehrmacht.
Notable memoirists of the camp include Primo Levi, Elie Wiesel, and Tadeusz Borowski.[195] Levi's If This is a Man, first published in Italy in 1947 as Se questo è un uomo, became a classic of Holocaust literature, an "imperishable masterpiece".[275][h] Wiesel wrote about his imprisonment at Auschwitz in Night (1960) and other works, and became a prominent spokesman against ethnic violence; in 1986, he was awarded the Nobel Peace Prize.[277] Camp survivor Simone Veil was later elected President of the European Parliament, serving from 1979 to 1982.[278] Two Auschwitz victims—Maximilian Kolbe, a priest who volunteered to die by starvation in place of a stranger, and Edith Stein, a Jewish convert to Catholicism—were later named saints of the Catholic Church.[279]

Since the end of the Holocaust, succeeding generations have striven to understand how such a horrific event as the Holocaust could have taken place. How could people be "so evil"? In an attempt to explore the topic, you might consider reading some books or watching films about the Holocaust. Hopefully, these reviews will help you decide where to begin.
The Germans isolated all the camps and sub-camps from the outside world and surrounded them with barbed wire fencing. All contact with the outside world was forbidden. However, the area administered by the commandant and patrolled by the SS camp garrison went beyond the grounds enclosed by barbed wire. It included an additional area of approximately 40 square kilometers (the so-called “Interessengebiet” - the interest zone), which lay around the Auschwitz I and Auschwitz II-Birkenau camps.
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]
Within the 191.97-ha serial property – which consists of three component parts: the former Auschwitz I camp, the former Auschwitz II-Birkenau camp and a mass grave of inmates – are located the most important structures related to the exceptional events that took place here and that bear testimony to their significance to humanity. It is the most representative part of the Auschwitz complex, which consisted of nearly 50 camps and sub-camps.
In less than 24 hours I shall be departing with my wife and two friends for a holiday in Krakow. As a minority of one I have been outvoted on whether we should visit Auschwitz Berkenau. Very reluctantly I will go. As an ex soldier, I am hardly a shrinking violet and perhaps more aware than some of the horrors of war or even lesser conflicts. I don't need to pore over such things. But many seem to cherish a ghoulish and prurient interest in such places. They are right to remember what happened there. From such knowledge mankind just might avoid or prevent anything similar happening again...but I doubt it. Look around the world. Horrors have existed, still exist and almost certainly will happen again. The scale is not the most significant factor. One child or adult butchered with machettes, bombs or bullets or bombs or tortured to death is just as horrific. Somehow I already feel guilty for allowing myself to go. For me it is almost on a par with digging up a coffin just to observe the putrefying remains of some departed soul. Why do some feel compelled to do that...does it awake in some a compassion that they did not previously have? No number of visits to such places can possibly make anyone feel and suffer as the inmates undoubtedly did. It takes some considerable effort to understand how a post-Auschwitz society can promote and run profiteering bus tours to one of the closest places humanity has to Hell. History cannot be changed by tears. Perhaps it is a forlorn hope but we would all do well to remember such places and events and then move forwards, using our best efforts to stop the slaughters that are occurring right now. That is where our consciences and efforts are most needed.
The Nuremberg trials were a series of military tribunals, held by the Allied forces after World War II in Nuremberg, Germany, to prosecute prominent members of the political, military, and economic leadership of Nazi Germany. The first of these trials was the 1945–1946 trial of the major war criminals before the International Military Tribunal (IMT).[456] This tribunal tried 22 political and military leaders of the Third Reich,[457] except for Adolf Hitler, Heinrich Himmler, and Joseph Goebbels, all of whom had committed suicide several months before.[456]

The last German offensive on the Western front, the Battle of the Bulge (Operation Wacht am Rhein), was an offensive launched towards the port of Antwerp in December 1944. Launched in poor weather against a thinly held Allied sector, it achieved surprise and initial success as Allied air power was grounded by cloud cover. Determined defence by US troops in places throughout the Ardennes, the lack of good roads and German supply shortages caused delays. Allied forces deployed to the flanks of the German penetration and as soon as the skies cleared, Allied aircraft returned to the battlefield. Allied counter-attacks soon forced back the Germans, who abandoned much equipment for lack of fuel.[citation needed]

The majority—probably about 90%—of the victims of Auschwitz Concentration Camp died in Birkenau. This means approximately a million people. The majority, more than nine out of every ten, were Jews. A large proportion of the more than 70 thousand Poles who died or were killed in the Auschwitz complex perished in Birkenau. So did approximately 20 thousand Gypsies, in addition to Soviet POWs and prisoners of other nationalities. 
Further trials at Nuremberg took place between 1946 and 1949, which tried another 185 defendants.[460] West Germany initially tried few ex-Nazis, but after the 1958 Ulm Einsatzkommando trial, the government set up a governmental agency to investigate crimes.[461] Other trials of Nazis and collaborators took place in Western and Eastern Europe. In 1960, Mossad agents captured Adolf Eichmann in Argentina and brought him to Israel to stand trial on 15 indictments, including war crimes, crimes against humanity, and crimes against the Jewish people. He was convicted in December 1961 and executed in June 1962. Eichmann's trial and death revived interest in war criminals and the Holocaust in general.[462]
His tasks for the Abwehr included collecting information on railways, military installations, and troop movements, as well as recruiting other spies within Czechoslovakia, in advance of a planned invasion of the country by Nazi Germany.[9] He was arrested by the Czech government for espionage on 18 July 1938 and immediately imprisoned, but was released as a political prisoner under the terms of the Munich Agreement, the instrument under which the Czech Sudetenland was annexed into Germany on 1 October.[10][11] Schindler applied for membership in the Nazi Party on 1 November and was accepted the following year.[12]
