Hi!
About films, "The last Mohican" is an excellent adventure film with French and Indian Wars setting
But surely you have already seen it, don't you?
The Patriot is awful IMHO. About the American revolution, the film "Revolution", is not very good, but much better than The Patriot for what i recall (long time since last time i saw it). At least you have Al Pacino and Nastasha Kinski

in there
Another oldie but good film is Drums along the Mohawk. Is a 1940s film by John Ford with Henry Fonda.
Not among the best Ford films but quite good.
Novels... i only know "The Adventures of Sargent Lamb" By Robert Graves. The adventures of a British soldier on the American Revolution. Quite nice. In Spain was published in two books. Not sure in other markets.
Regards!
