The key to Napoleon’s success was that he was a living computer. His mental skills enabled him to bring greater force to bear in the required place at the key moment in time. Everything thing he did - his strategy, his planning, his logistics, his tactics were all geared towards that objective. As a result, he won every fought battle he fought - except for one. And that is the one where Blucher did what he promised Wellington he would do and brought superior force to bear in the required place at the key moment in time.
Somehow I never considered the Russian invasion to be a success.
I have read a number of accounts of Napeoleon and I agree with you. He was an extraordinary man who could simultaneously run military campaigns and a country. His powers of mental focus were unheard of then or since. He could dictate orders that were simple, clear, and precise. And he was able to operate this way days on end without sleep. His combination of intelligence, personality, and constitution made him a giant that took of of Europe to bring down. Next to him, Hitler was a midget.
