That is very interesting.
I found a quote about that:
“Field-Marshall Karl Gerd Von Rundstedt of Germany. When interviewed by newspapermen, he readily admitted how important oil had been in World War two. In fact, he attributed German defeat to three factors, to wit: (1) the Allied bombing sorties (strategic and tactical); (2) the bombardments by Allied naval guns; and (3) Germany’s own deficiency in oil, especially in the form of gasoline.”
