The new set of ACW rules "Guns at Gettysburg" is now at the printers/publishers, it is hoped they will be out late 2006.
They are a based on the General de Brigade Napoleonic rules system adapted to the ACW period and maintain the regiment as the basic wargames unit, catering for brigade, divisional and even corps actions.
Updates, rules questions and discussion forum will be housed on this, the joint GdeB website.
