"Yankees & Rebels" is a 2 player modular wargame, capable of simulating the major battles of the American Civil War. The primary scenario included with the game is called "The Three Days of Gettysburg". The game is played on a hexagonal board, onto which cardboard hexes are placed, to simulate the layout of different battlefields. Playing pieces (military units) are represented by stand-up cardboard markers; with images on the reverse (facing the opponent) and schematic information on front (facing the owner). Unit strengths are tracked through the use of plastic chips. Specially marked dice are used to resolve combat.
