We used different forces and slightly modified terrain (a house was substituted for the southern redoubt).
Cavalry were involved to playtest some rules.
But the dice were with the Hessians and they sent the Americans back down the hill. After this, the Americans tried a few more times, but each attack was piecemeal and defeated.
A fun game, thanks to my Gentlemen at arms. All figures 28mm Perry, Foundry and Front Rank. Houses are Dan's from 4Ground. The redoubt is part of a fort my father made me some years ago.
