The Horse Artillery Brigade of the Army of the Potomac was a brigade of various batteries of horse artillery during the American Civil War.
Made up almost entirely of individual, company-strength batteries from the Regular Army’s five artillery regiments, the Horse Artillery operated under the command umbrella of the Cavalry Corps. The Horse Artillery differed from other light artillery (also known as “mounted” artillery) in that each member of the unit traveled on his own horse, rather than the traditional light artillery practice of some riding horses, while others rode on the limbers and caissons, with still others traveling on foot.
