You write, "Napoleon was not 'outgeneraled' by Alexander. "
He certainly was in 1812. Unless you want to argue that N.'s 1812 invasion was somehow another great victory.
A. had a simple common sense strategic plan to deal with the anticipated attack and it worked. Sometimes simple common sense can defeat genius. N. could have won the campaign if A. did something stupid like go on the attack; which most all of the hotheads in the Russian Army seemed to demand. It took real guts, and smarts, to do everything possible to preserve the army and let N. take Moscow and then leaving him to sit there unmolested as long as he wanted. Of course, N. was incompetent in managing his 1812 campaign and as a result his army was defeated by a weaker foe.
