non fiction book?

it's a rare book, but try "The French Armies in the Seven Year's War: A Study in Military Organisation and Administration, N.C., 1967" by Lee Kennett.

I'll level with you: it won't be up your alley--you might hate me for it in fact. Having said that, it has good laughs, like the account of an officer describing his general's routine, or the epic feud between Fenestre and d'Agay. even after almost 4 years, the lulz never cease to amaze me.
