I have read all of that before. The standard story as told since WW2 never did explain a lot of things very well to me. Wintering in Moscow is a pretty lame reason to not order winter equipment, fuel or lubricants. I do not think taking Moscow would have won the war for them in any case. It is not like the Germans fell just a few miles short of winning. The USSR was something like 5,000 miles west to east and the Germans never got more than 900 miles or so into it. I guess it is possible that the General Staff was simply very stupid but I do not believe that. Barbarossa seems to me like it was more desperation rather than a well thought out plan. I thought this book does a good job of explaining why it looked that way.
Hitler had gone through the Allied armies like a knife through butter and figured he would do the same with an even less prepared army.
Don’t forget by this time his brains were being fried by the crank Dr. Morrel. His judgment had turned to outright idiocy.
There was no desperation on Germany’s part and no impending invasion by Stalin. Makes no sense.
