Russian power in the Kremlin have been widely spread opinion that the German Army will meet the same fate as Napoleon's army, faced with unusual for her harsh Russian climate and nature. However, we are sitting in their trenches, seen only around the vast snowy plains and knew little about what was going on outside of our sector. Then, in December 1941, we did not suspect that soon we will have to fight on our site is not even for the sake of winning, but simply to survive. The problem is largely rooted also in the fact that there was no adequate theoretical work on the conduct of the war in the conditions with which we are faced in Russia. This country was so vast, it seemed to us endless, and was inhabited by people of whom we name anything is not talking. From history we can recall only two examples of the war on the Russian territory. Firstly, the loser Napoleon's campaign. Second, the fighting in the First World. The realities of both wars contained the fighting in the winter, when Russia had to resist the enemies huge masses of its soldiers.
