The crest represents the gallant service of Lieutenant Richard Metcalf's battery at Spotsylvania, 4-24 May 1864, when it charged earthworks firing its guns and then ran them up by hand to a new position, to the Bloody Angle and fired repeatedly. This is purported to be the only recorded instance in the Civil War of a battery charging on breastworks.
