The program is about three ex-soldiers, two at one time fighting for the Union side and one for the Confederate, who traveled together across the West, fighting trouble and bad guys. The series starred Kent Taylor as ex-Union Captain Jim Flagg, Jan Merlin as former Confederate Lieutenant Colin Kirby, and Peter Whitney as former Union Sergeant Buck Sinclair.
Prior to his starring role in The Rough Riders, Kent Taylor previously starred in still another Ziv Television-produced series, Boston Blackie, which aired for two seasons in syndication from 1951–53.[1]
