Your product development sounds like a lot of fun. Some others that may fit the bill:
The Pennsylvania and Virgina riflemen's insanely rapid pace (600 miles in 21 days?!) on their walk to Boston in 1775. I personally doubt anyone could walk that fast for so long, with gear and rifles (could they then?), but it's part of the lore. Just a random Web search found this:
http://www.americanrevolution.org/riflemen.htmlA short story about "Tarleton's quarter" (or lack thereof): for example (again from a fast Web search),
http://home.golden.net/~marg/bansite/banecdotes/96quarter.htmlAnything about the British prison ships in Charleston and New York. Someone in this group posted here about an article in the DAR magazine recently.
Just about anything to do with the Southern theater. For example, Bunker Hill is well known. Is the 1779 failed assault on Savannah, with French help? I don't think so. Ward, in his War of the Revolution (Macmillan, 1952), says Savannah was similar to Bunker Hill in its ferocity and scale.
The "first salute" of the American flag by the Dutch colony at St. Eustatius in the West Indies (the subject of Barbara Tuchman's book The First Salute).
The Jane McCrea (sp?) atrocity that so inspired American militia before Saratoga (any Saratoga book would have an account, I imagine).
Good luck.
