Gray Ghosts of the Confederacy is a history of the Confederate guerrillas who, under the ruthless command of such men as William C. Quantrill and ""Bloody Bill"" Anderson, plunged Missouri into a bloody, vicious conflict of an intensity unequaled in any other theater of the Civil War. Among their numbers were Frank and Jesse James and Cole and James Younger, who would later become infamous by extending the tactics they had learned during the war into civilian life.
