The best thing I could recommend would be The Campaigns of Napoleon by David G. Chandler. It isn't a very easy book to find and right now it's about 68 dollars on Amazon for it used, but it is the Bible for the military aspect of the Napoleonic Wars.

I would recommend finding some thing better to read than Chandler's work. It is extremely dry and usually offers very little context to why these battles and wars are being fought. For example the Milan/Berlin decrees there is one sentence mentioned of them. The Contintental system is not discussed much either.

This can be defended on the grounds that the book is about his ARMY and not about the politics and stuff going on around it. OK, but the writing style is bland and bad in some places. For example during the Russian campaign he repeated refers to "Holy Russia" and various references to this theme that the Russians are very religious and mystical, repeated over and over w/o any attempt to flesh this out. He also refers to Caulincourt being killed at Borodino then a few pages later starts referring to Caulincort again! Turns out he is talking about the brother there. No explanation.

The whole thing seems like just an endless litany of dates and places that Napoleon's corps stopped at on a decade long excursion through Europe. That's all it is; I dont recall much mention of tactics either but maybe I forget..

I know Chandler was a great professor and have no doubt he had great knowledge of Napoleon stuff. But as a piece of writing this book is bad. Great example of people with vast amounts of knowledge who cannot communicate it well (at least not in this book).

Highly overrated.
