Catesby ap Roger Jones
Catesby ap Roger Jones (April 15, 1821 – June 20, 1877) was an American naval officer who served in the United States Navy before resigning to become a commander in the Confederate States Navy during the American Civil War, where he distinguished himself as an ordnance expert and acting commander of the ironclad CSS Virginia in the Battle of Hampton Roads.[1][2] Born at Fairfield Plantation in Frederick County, Virginia, to Major General Roger ap Catesby Jones and Mary Ann Mason Page—a cousin of Robert E. Lee—Jones entered the U.S. Navy as a midshipman on June 18, 1836, aboard the USS Macedonian under his uncle, Commodore Thomas ap Catesby Jones, a War of 1812 hero.[1] He served on multiple vessels, including the USS Columbia, and was promoted to lieutenant in 1849, during which time he collaborated with John A. B. Dahlgren on developing the IX-inch shell gun, establishing his reputation in naval ordnance.[1] Following Virginia's secession, Jones resigned from the U.S. Navy on April 17, 1861—a move noted as a significant loss to the Union due to his expertise—and was appointed a captain in the Virginia Navy before joining the Confederate service as a lieutenant.[1][2] In the Confederacy, Jones contributed to fortifications on Jamestown Island and served as executive officer of the CSS Virginia, overseeing armor testing that influenced its design—such as rejecting insufficient three-layer plating—and accelerating its construction from a scuttled steam frigate.[1] During the Battle of Hampton Roads on March 8–9, 1862, he assumed command after Captain Franklin Buchanan was wounded, leading the Virginia to sink the USS Cumberland and USS Congress before engaging the USS Monitor in a drawn four-hour duel that demonstrated the obsolescence of wooden navies.[1][3] Later, he supervised the Selma Naval Ordnance Works, producing over 70 Brooke rifled guns critical to Confederate artillery efforts in collaboration with John M. Brooke.[1][2] Paroled in 1865, Jones attempted a military supply business that failed before working in insurance in Selma, Alabama, until his death.[1]
