Well, In a way. Napoleon was never the infallible general he’'s portrayed to be. He often got very lucky and got quite far by way of the aura he had aquired. Tactically he was often bailed out. After Russia and Neurenberg the allied soldiers no longer believed in his invincibility and he made quite a few tactical mistakes at Waterloo.

But I think that Davout was his best Marshall who made his most incredible victories possible. However he is not talked about much.
