I decided to base these models singly. Most AWI battles have very little cavalry so it won't be too much of a chore to move the unit. I don't even see the need to bother with a movement tray. Where mounted models were more common would be the innumerable skirmishes that took place between battles, making these perfect for 1:1 games of, say... Donnybrook?
At Cowpens, there seem to have been around 180 American horse and nearly 300 British (well, technically more Americans since most were British Legion with a few 17th Light Dragoons). I plan to paint 18 American horse (12 Continental and State Dragoons and 6 Militia) and 30 British horse (24 British Legion and 6 17th Light Dragoons). Along with the singly based skirmish infantry I have planned for both sides, I should have plenty of models for fighting skirmish games.
I hope to have the next squadron up in a few days... the 1st Continental Dragoons.
