The second game I ran at Origins 2009 was Guilford Court House; a four player, three hour game.
Looking at the American position from the British point of view.
The British advance. They will shake out their line to attack the Americans all along their first line, with a slight overlap on the British left.
The Americans decided to bring their entire army forward to the first line for a stand there.
The British lost every melee except one. After tow hours of play, they conceded.
I have run this game twelve times. I recommend it as a well balanced, fun game. It doesn't take alot of troops or table.
