From 1942, members of the Bureau of Information and Propaganda of the Warsaw-area Home Army published reports based on the accounts of escapees. The first was a fictional memoir, "Oświęcim. Pamiętnik więźnia" ("Auschwitz: Diary of a prisoner") by Halina Krahelska, published in April 1942 in Warsaw. Also published in 1942 was the pamphlet Obóz śmierci (Camp of Death) by Natalia Zarembina, and W piekle (In Hell) by Zofia Kossak-Szczucka, founder of Żegota. In March 1944, the Polish Labor Group in New York published a report in English, "Oswiecim, Camp of Death (Underground Report)", with a foreword by Florence Jaffray Harriman, which described the gassing of prisoners from 1942.
From the overpass, the road leads directly to the Gate of Death. The railroad spur line that goes through the gate house begins on the left side of the gate, about a quarter of a mile away, and curves around until it forms a straight line in front of the gate. Trains coming from the west entered the Birkenau camp from tracks on the left side of the gate, as you are facing it, and did not pass the railroad station in the town of Auschwitz. Trains coming from the opposite direction passed the train station in Auschwitz and then entered the camp on the spur line. The train tracks end only a few yards from two of the gas chambers inside the Birkenau camp.
In this year, 1929, I became convinced that tanks working on their own or in conjunction with infantry could never achieve decisive importance. My historical studies, the exercises carried out in England and our own experience with mock-ups had persuaded me that the tanks would never be able to produce their full effect until the other weapons on whose support they must inevitably rely were brought up to their standard of speed and of cross-country performance. In such formation of all arms, the tanks must play primary role, the other weapons being subordinated to the requirements of the armour. It would be wrong to include tanks in infantry divisions; what was needed were armoured divisions which would include all the supporting arms needed to allow the tanks to fight with full effect.
Overy wrote that blitzkrieg as a "coherent military and economic concept has proven a difficult strategy to defend in light of the evidence". Milward's theory was contrary to Hitler's and German planners' intentions. The Germans, aware of the errors of the First World War, rejected the concept of organising its economy to fight only a short war. Therefore, focus was given to the development of armament in depth for a long war, instead of armament in breadth for a short war. Hitler claimed that relying on surprise alone was "criminal" and that "we have to prepare for a long war along with surprise attack". During the winter of 1939–40, Hitler demobilised many troops from the army to return as skilled workers to factories because the war would be decided by production, not a quick "Panzer operation".
Jews were forced to move, often to different cities or countries, and live in designated areas, referred to as ghettos. Most of the ghettos were “open” which meant Jews were free to come and go during the daytime. As time past, more and more ghettos became “closed” meaning that Jews were trapped and not allowed to leave. No ghettos were ever established within the borders of Germany and most were only meant as a temporary means of isolating Jews from the German population until they could be moved elsewhere.
