Artillery on Howison Hill. The cannon on the left is a large 30 pounder Parrott.
Like Lee's Hill, Howison Hill was crowned with Confederate artillery that blasted the Union attackers in front of Marye's Heights. A large 30 pounder Parrot was among the guns at this location. This type of gun is classified as siege artillery and not usually found on a battlefield. Besides one here, the Confederates had one on Lee's Hill.
