Though it is popular to think of the 1939-1941 "Blitzkrieg" era Wehrmacht as a near unstoppable war machine, reality is far different. Material shortages similar to those afflicting the German army in the years 1944-1945 were all too apparent during the Third Reich's early war march across Europe and the Mediterranean littoral. Ironically, however these shortages had far more to do with German decision making than the commonly held view that Germany didn't have enough economic resources capable of being converted into military strength.
