You will note "gaps" in the numbering for the infantry regiments. This is because Pennsylvania numbered all regiments, regardless of branch, in sequence depending on when the regiment was raised. For example, the 6th Cavalry was also numbered the 70th Volunteer Regiment since it was raised between the 69th Infantry and the 71st Infantry, thereby there is no 70th Infantry.
