Robert E. Lee: Civil War General was a game by Sierra that recreated the battles of the Eastern Theater in the American Civil War. It used a hex-map and randomized numbers to attain hits and damage to enemy units. It allowed two players to play head to head or a single player to play against the AI. A linked campaign was available to play, but only as the Confederacy. It was basically a cardboard and paper wargame ported over to the PC.
