Reenforced by Wheeler’s New York Battery Captain Dilger advanced twice from this position. Retired with the 11th Corps, but halted and again engaged the enemy before crossing the bridge into the town. During the remainder of the battle the Battery held the extreme right of Maj. Osborn’s line on Cemetery Hill. Loss 13 wounded.
