Rapid Rules - Blue & Gray is an abstract strategy game for 2 with a thin American Civil War theme.

About Blue and Gray, from BoardGameGeek:

Blue and Gray was granted a patent in 1903, but possibly was not published until Sid Sackson included it in A Gamut of Games In Blue and Gray, each player begins with 17 guards and one captain set up on the line intersections of a 9 × 9 grid board. The object of the game is to advance the captain to the center of the board following an outlined path of 17 steps. However, the captain can only advance if the next step along the path is unoccupied by friendly or opposing guards. Guards can move along lines in any direction (except over the central point) and can capture each other by jumping, as in checkers. Super Blue and Gray took this game one step further
