The German's drove deep in Russia on the first day with very little resistance.

Eventually Stalin ordered a rapid retreat with the Russian's burning everything of value that the German's could have used.
Then the weather turned and the German's got bogged down by the red mud of fall.
Its interesting that the Russian citizens probably hated Stalin more then Hitler, and if the German's would have taken the role of liberators instead of following a brutal strategy of basically extermination that the Russian's might have tried to help the German's in driving to Moscow.
Hitler's ego also got the best of him as he decided to drive on Stalingrad which is where the German Army was eventually defeated.
