"Saratoga" by Richard Ketchum was very good. For a very thorough view of the French and Indian War, "Empires At War" by William M. Fowler, Jr. "Rise To Rebellion" and "The Glorious Cause" by Jeff Shaara are, technically, Revolutionary War novels, but very good history. Allan Eckert and James Alexander Thom are hard to beat. I particularly like "That Dark And Bloody River", by Eckert. "1776" by David McCullough was, also, very good.
All this leads up to the finest treatment of the Revolutionary War that I've read, to date, which is "A New Age Now Begins" (two volumes), by Page Smith. The two books are each huge, but don't be put off by that -- Smith's writing style and the emphasis he places on people, at least as much as on events, holds your interest from the opening pages. In a few pages he lays out a scene of Massachusetts farmers slaughtering redcoats on the road from Concord to Boston, and of colonists being trapped by sorties of vengeful Englishmen and cursing the soldiers as they die -- then poses the question, "How did it come to this?" I was hooked, at that point, and some 1800 pages later I realized how relevant -- often in frightening ways -- the history of the Revolution is to the course our country seems to be taking today. I'm about ready to begin my third reading, and fully expect to find much that is new and valuable to me.
