In tactical terms, Hitler was more creative and innovative than Napoleon. Napoleon inherited the methods of warfare of Revolutionary France, but introduced no new ideas. Hitler on the other hand absorbed, promoted and put into effect the radical new ideas underlying Blitzkrieg warfare, largely against Conservative opinion. He masterminded the coup that captured Eban Emael, and endorsed daring and radical strategies, such as the Manstein Plan, the attack on Norway, and the parachute landing on Crete. Hitler also had more personal charisma. Everybody who entered into his presence fell under his spell. The rebellion which toppled Napoleon in 1814 was inconceivable in Germany. The Germans stayed loyal to Hitler to the point of his death and the utter collapse of his nation. Hitler's motivation was ideological and philosophical, however dark his ideas seem to us now. Napoleon was motivated solely by personal power, as evidenced by his remark that he had an income of a million soldiers lives a year. Hitler lived a much more ascetic and simple life than Napoleon, who was an epicure and a womaniser
He did no such thing. Blitzkrieg tactics were developed by younger Heer generals not by Hitler. He basically backed daring strategies made by others because it appealed to him as being new and fresh instead of old and stale. I doubt very much he understood them well. There was a reason why he only made corporal.
Napoleon on the other hand fought on the field of battle and directed them. Napoleon very much knew warfare and tactics. If they were developed before him he put them to better use than anyone else did. Napoleon earned the rank of general it wasn't just handed to him.
