The Ironclad Board was an advisory board, established by the Union, in which year, in response to the construction of the "CSS Virginia" by the Confederacy during the US Civil War,primary goal of the Ironclad Board was to develop more battle-worthy ("ironclad") ships, including the USS Monitor, an iron-hulled steamship?
USS Monitor USS "Monitor" was an iron-hulled steamship. Built during the American Civil War, she was the first ironclad warship commissioned by the Union Navy. "Monitor" is most famous for her central role in the Battle of Hampton Roads on 9 March 1862, where, under the command of Lieutenant John Worden, she fought the casemate ironclad  (built on the hull of the former steam frigate USS "Merrimack" ) to a standstill. The unique design of the ship, distinguished by its revolving turret which was designed by American inventor Theodore Timby, was quickly duplicated and established the monitor type of warship.
Battle of Wassaw Sound The Battle of Wassaw Sound (or the Capture of the CSS "Atlanta") was an American Civil War naval battle between the Confederate ram CSS "Atlanta" and the "Passaic"-class ironclad monitors USS "Weehawken" and USS "Nahant" and the gunboat USS "Cimmerone" (later named "Cimmaron"), which took place on 17 June 1863 in Wassaw Sound, a bay in the present day state of Georgia. "Atlanta" ran aground while attempting to break the Union blockade, and after a short battle surrendered to the Union forces. Captain Rodgers became a national hero, and he was promoted to Commodore and received the Thanks of Congress as a result of his decisive victory.
