Francis Parkmans Musket and Tomahawk is a fascinating account of the French and Indian War of the 1750s, given its American writer it is surprisingly eloquent.
It certainly is well researched, and full.
Going into the terrain and climate, and including a naval aspect of the campaign, good stuff particularly if you are reseaching the subject.
Unless you concentrate it can be a bit heavy going, and so will not be to everyones taste, but i found it quite good.
Perhaps on the pricey side for a paperback.
