The Confederacy experimented with the submarine
CSS, which proved unsuccessful, and with the ironclad
CSS, rebuilt from the sunken Union ship
. On March 8, 1862,
Virginia inflicted significant damage on the Union's wooden fleet, but the next day, the first Union ironclad,
USS, arrived to challenge it in the
Chesapeake Bay. The resulting three-hour
Battle of Hampton Roads was a draw, proving ironclads were effective warships. The Confederacy scuttled the
Virginia to prevent its capture, while the Union built many copies of the
Monitor. The Confederacy's efforts to obtain warships from
Great Britain failed, as Britain had no interest in selling warships to a nation at war with a stronger enemy and feared souring relations with the US.
