John Martin has written a set of free wargames rules for the American Civil War based on Games Workshop’s Warmaster. I think that things have come full circle here, because Warmaster obviously took much of its inspiration from the seminal ACW rules set, “Fire and Fury.” Not that GW would ever admit that. After all, according to the Evil Empire, miniature wargaming is the “Games Workshop Hobby”, which precludes the acknowledgement of any other rules set or miniatures.
