The american cavalry, a ramshackle unit of mounted militia inspired on "the patriot" movie
The cavalry'll be able to dismount hence this "unmounted" marker
Unit dismounted in line, 4th base kept back to hold the horses, an idea taken from the Obscure Battles blog, an excellent source of historical articles with a sprinkling of wargaming, which I recommend reading.
Washington on Blueskin (yes the horse's name is also a mistery to me)
Random pointing general
My favourite model of the army: general with Cowpens map!
British attacking the first american line with the second hiding sneakily behind the hill
I also found this page full of Don Troiani's works, I'm sure some of you'll like it
