Chickamauga: Bloody September, 1863 (CBS) is volume four of Paul Koenig’s Bloody Civil War Series. It is a two-player wargame simulating the second bloodiest battle of the war and the biggest defeat for the Union in the West. As the Confederate player, you are in the rare position of outnumbering your enemy. On the first day you must take Thomas' initial blow, and then knock him back, setting up for the decisive battle on Day 2 after the arrival of Longstreet. As the Union player, you must hope that Thomas can be the Rock of Chickamauga once again. Your army arrives slowly, and you will be hard pressed to hold back the Rebels.
