The Great Campaigns of the American Civil War series, commonly abbreviated as GCACW, is a highly-regarded, operational-level series of war games covering famous battles of the American Civil War. The series was started by Avalon Hill in 1992 with its first entry, Stonewall Jackson's Way, designed by Joseph M. Balkoski. Avalon Hill went on to add 5 more games to the series.
While Joseph M. Balkoski was solely responsible for designing the first 4 games in the series, Ed Beach designed Stonewall's Last Battle and the two collaborated together on On to Richmond!. After Avalon Hill closed down in 1998, MMP picked up the license and published an additional game in 2001 (with more to come). Ed Beach has been taking the lead on the series since its move to MMP.
