Just saw Swoops mention of "Arundel", by Kenneth Roberts, He wrote several others about the French and Indian War/ Revolutionary War era's, Rabble in Arms and Northwest Passage were both real good, especially since all three of them involve places right around me

He also wrote several about the Revolution and War of 1812 at sea, "Lydia Bailey" is the only one of those titles I remember .
Can't think of the titles but Alan Ekert wrote a series of books about that era as well though his tend to take place in upstate NY and the Ohio river country (IIRC "The Frontiersmen" was the first of the series)
I finished the Jeff Shaara book, and went on to read "Steel Wave", about WWII. niether of them were as good as his Civil war books.
For Sword and Sorcery buffs look in the used book stores for the original "Thieves World" series.
They are collections of short stories by several authors all set in the same place, a dying city that is considered the anus of a decaying Empire, In the Dragon Lance series the thieves and scoundrel were charming rogues, in thieves world they are scumbags, even the so called "good guys" are not people you would invite to dinner

Anything by Jack Higgins, ("The Eagle has landed" is his best known )
The earlier works of Leon Uris," Battle Cry" is a classic of the Marines in WWII, based on his own experience, "Trinity" and "Redemption" are about the troubles in Northern Ireland. He also wrote several about the Jews and Israel , "Exodus" comes to mind and I can see "Mila 18" on the book shelf which is about the Warsaw Ghetto uprising.
