I am not sure Napoleon was ever really himself after the Russian campaign. What he expected after his victory at Borodino and what really turned out was very different. Expecting the Russians to surrender only having them chase him all the way back to France may have put some doubt in his mind. Maybe that doubt is what affected his decisions at a place like Waterloo. I know in sports that if you loose your confidence it can be hard to get back. I imagine the same could be said about war generals. Just a thought. Enjoyed the post.
