I agree with Panzer that the Polish campaign was if anything a triump of tactical airpower.The use of Stuka´s as flying artillery was something not seen before. For example in the Soviet/ Finnish Winter War that followed soon after this Campaign, the Soviets were not able to use their airforce in such manner at all, which pointed out a crucial weakness in their doctrine of mobile warfare during the time. Soviet airforce was not able to destroy the relatively weak Finnish artillery formations, not it could hamper Finnish side from moving their reserves behind the lines. Similar shortcomings were spotted in the quality of Soviet fighter doctrine and strategic airforce. The former was in world of hurt with the puny Finnish airforce and the latter had huge problems coordinating mass bombings against Finnish cities, railroads and other infrastructure.

Also what should be pointed out in the Polish campaign was that the quality of German armoured forces compared to Polish was not clearly in German favour and to me Polish used their own armoured forces and anti tank capabilities with superior skill compared for example to Western Allies in French campaign. I also agree with Panzer that the Polish put up a fierce resistance with the resources they had and calling that "rolling over" is bit more then misinformed.
