Robert Harvey certainly does not seem to think so, whether through his own opinion or through the evidence he gives.
In The War Of Wars Harvey really does give Boney's reputation and Myth a good thrashing, showing him to be considered by his more able Marshals as nothing but an equal, a partner in the splitting of Europes spoils. A maniac autocrat of the first order (he is most damning of his supression of the constitution by force) who were it not for the Scheming Talleyrand and Fuche would be lost on International and even national polotics. Was averse to any kind of peace as his power rested upon a wartime army and national cohesion.
Indeed in some of his private letters and accounts of his meetings with those with whom he was displeased. he comes across as childlike and politically inept.

I am no expert and I doubt any of us are but I still would ask for you're interpretation of Nappy.
