Rally Round the Flag is an operational and tactical game system set in the American Civil War and focuses on both the historical battle of Gettysburg and other What If scenarios around the Gettysburg battle site. Rally Round the Flag can be played at three levels. The Corps Command game is played with each unit representing a division. The Division Command game is played with each unit representing a brigade. And the Brigade Command game is played with each unit representing a regiment. To win Rally Round the Flag, a player must force their opponent to retreat from the battlefield or control more Victory Points at the end of the game. The system is designed to focus on the mechanics of holding key pieces of terrain and using the battle system of card play to simulate the tactics and training of each unit. -description from publisher
