"Blitzkrieg" — is to destroy the enemy in the course of a single large transaction or several related transactions among themselves.
Poland was defeated, not too far away because of the technical advantages of aircraft and armored vehicles Nazis.
It is in 1940, correctly noted Russian researcher GS Isserson. He noted three main causes of the defeat of Poles frisky:
-The first reason: Poles are very much believe their allies — France and the UK, considering that the main forces of Germany will be associated fought on the Western Front. Against Poland, wonder, Berlin put up no more than 20 divisions.
Polish command, was also train believes that the main forces of the Luftwaffe will fight in the West. What would really help UK air and naval forces. Polish elite confidently, looked lessons of the past — London has always tried to use someone else's power.
Therefore, and with the mobilization took the cocky considering that 20 divisions of the Wehrmacht, beat off the peacetime army.
— The second reason: In Warsaw believed that Berlin will concentrate the main forces against Danzig and Posen, trying to recover, lost under the Versailles peace in 1918. Polish top, just did not realize that Hitler was planning a complete defeat and occupation of Poland, and not part of it. Because the direction of Silesia, where the Germans inflicted a major blow, blinked.
3rd reason: Warsaw believed that Berlin was not immediately able to join the fight by all means, take time to otmobilizatsiyu and concentration of forces, ie, the time will come that even the Polish army will be able to successfully attack and capture of East Prussia and Danzig. Warsaw prohlopali the time that Germany has already carried out the mobilization and concentration.
Polish army just ahead, the Polish army only has mobilized and transported troops to the border. This allowed the Wehrmacht to the numerical limits have an advantage and Polish forces to thrash parts.
In other words, Poland almost all ruined their self-confidence and faith in the Allies. If they created a sober calculation, the blitzkrieg would the Germans failed, fastened to languid fights. The Wehrmacht would have suffered severe losses, breaking the Polish army mobilized.
This experience later Wehrmacht partly managed to replicate and with the Soviet Union in the summer of 1941, particularly in Belarus, the Western military environment.
