What is clear is the practical implementation of this doctrine in a wide and successful range of scenarios by Guderian and other Germans during the war. From early combined-arms river crossings and penetration exploitations during the advance in France in 1940 to massive sweeping advances in Russia in 1941, Guderian showed a mastery and innovation that inspired many others. This leadership was supported and fostered by the Reichswehr General Staff system, which worked the Army to greater and greater levels of capability through massive and systematic Movement Warfare war games in the 1930s.
Those prisoners capable, began forcibly marching at the moment when Soviet soldiers were liberating Cracow, some 60 kilometers from the camp. In marching columns escorted by heavily armed SS guards, these 58,000 men and women prisoners were led out of Auschwitz from January 17-21. Many prisoners lost their lives during this tragic evacuation, known as the Death March.
Inmates at Birkenau numbered around 100,000 at their peak. They were of many different nationalities, but the vast majority of those that entered the camp were unregistered Jews, many of whom were immediately sent to their deaths in the gas chambers. Women and children stood the least chance of survival, and many died even before arriving at Birkenau due to the appalling conditions of the railway journeys. The unloading platform, where the brisk selection process was conducted, remains. Apart from physically fit men (who often perished later from the rigours of the camp) it was often only an accident of birth that merited a possibility of survival. Large numbers of twins survived until liberation as they were objects of interest to the research of Dr. Josef Mengele - a man disliked even by his Nazi peers.
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.
