Billy Hazard is shown as a member of the 1st U.S. Sharpshooters, a.k.a., Berdan's Sharpshooters, throughout the war. However, Hiram Berdan was extremely strict about forming his regiments and companies by state. As a Pennsylvanian, Billy would have been assigned to Company C, 2nd U.S. Sharpshooters, the only unit in either regiment that accepted Pennsylvanians.
