From the game's introduction... "Col. Mosby, the Gray Ghost of Confederate fame, and his Mosby Raiders are harassing the Union lines in Virginia, West Virginia and Maryland. Each of the 4 Mosby Raiders proceeds from Start and reports to the Gray Ghost Headquarters. Here each Raider receives a 'Secret Mission' to perform, as show on the Secret Mission Card which he draws. The first Raider to complete his Secret Mission, capture 5 Union Soldiers, and return to Headquarters, is the winner. Being wounded, captured and ambushed add to the hazards of play." Movement in the game is driven by a simple spinner.
