In 1974, researcher John G. Newton announced that the remains of the USS Monitor had finally been found. The vessel was the first ironclad warship to fight during the Civil War, sporting armor plating made by Baltimore iron manufacturer Horace Abbott. The Monitor, which is best known for its clash with the CSS Virginia during the Battle of Hampton Roads, sank in 1862 after a storm off of Cape Hatteras in North Carolina.
