The epic battle between the ironclad CSS Virginia (formerly the steam frigate USS Merrimack) and the USS Monitor made history not simply because ironclads were involved, but rather because it was the first engagement between two ironclads. The outcome of the battle is generally considered to have been a draw, although Monitor was firing solid shot throughout and designer John Ericsson was reportedly furious that Monitor had not been supplied with explosive shells, which he was sure would have sunk Virginia had they been employed by firing at Virginia’s waterline. As it was, Monitor probably did more overall damage to Virginia. Monitor had heavier guns and cracked Virginia’s armor in several places, whereas Monitor suffered only dents, literally.
