Postcard from the Revolution (2004)

From the designer's web site:

"Postcard from the Revolution is an attempt to make a very small war game that plays like a war game and not an abstract strategy game. As its name suggests, Postcard from the Revolution is a post card that includes the board, counters, rules and historical background of a single battle from the American Revolution. Plus, it is perfectly legal to send through the mail. The battles of Germantown and Brandywine Creek have been written for Postcard from the Revolution."
