Histoire & Collections of France publishes a series of big hardcover books on various battles of the Napoleonic Wars, and I own nearly all of them. They are beautiful works, done in full color on glossy paper, with numerous maps, historical paintings, and uniform plates. The text is so badly translated from the French as to be almost unintelligible, but I've found them very useful over the years as I paint my Napoleonic miniatures.
One of my great frustrations with Osprey's Men at Arms series is that the books usually have a broad theme (French infantry of the Napoleonic Wars), but a limited set of color plate subjects (farrier of the 9th Line, or pastry chef of the Corsican rangers, rather than fusilier 1800, fusilier, 1805, fusilier, 1809, fusilier 1812, fusilier 1815.
Well, here comes Histoire & Collections to the rescue. A few weeks ago I picked up their new softcover book on French Chasseurs a Cheval 1792-1800, and I liked it so well that I bought their books on cuirassiers, aides de camp, and both volumes on hussars.
The cuirassiers volume is 80 pages of goodness. The book begins with an overview of the development and history of the cuirassier arm, and H&C have apparently hired a real translator, as the text is clear and informative. The book details squadron drill, showing where the officers, NCOs, and troopers were located in several formations, then moves on to the deployment of squadrons within the regiment. This is good stuff, very useful to the modeler and wargamer.
Now that I have a proper resource, I can start depicting the various regiments of cuirassiers. You can find these books on Amazon (tell Hippolyta that Scott sent you; she'll either give you a deep discount or castrate you--I'm not sure which).
