When this Regiment was first organized in September, 1861, it was recorded on some of the rolls for the 2nd Regiment, but the Adjutant & Inspector General's Office mustered it on their records as the 1st Regt. Va. Arty. In 1861, there was also a 1st Regt. Va. "Light" Arty. that led to further confusion. Due to the attrition of war, the regiment was reduced to a battalion in September 1864 and also with a redesignation as the 1st Battalion Virginia "Light" Artillery.
