The map represents the Charlestown peninsula where the battle was fought and is very clear and done in a series of greens and blues with the surrounding Mystic River and Boston Harbor nicely set off by the hex grid. The unit counters are differentiated by color for the British and Connecticut, Massachusetts, and New Hampshire men. Each unit contains indicators for morale, stacking value, set-up group, fire modifier and movement allowance, along with a silhouette of an infantryman or unlimbered artillery piece. There are also leader counters which contain a melee and movement bonus number. Terrain is neatly dealt with by assigning a different stacking value total for each different kind of hex.
American values are mostly low, reflecting shortages of ammunition and bayonets.
Twice during the game, at the beginning of their turn, the British can declare a reorganization turn, which allows them to return to play units which have previously been eliminated by American action. This represents the reorganization of routed units at the beachhead. In addition, the Americans can declare a general retreat. The most important rules are the American command control or rather, lack of it. During the actual battle, the American units were crippled by a lack of co-operation between units from different states.
