DescriptionThe 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 CSS Virginia (built on the hull of the former steam frigate USS Merrimack) to a standoff. The unique design of the ship, distinguished by its revolving turret, was quickly duplicated and established the Monitor type of warship. Designed by the Swedish-born engineer and inventor John Ericsson, and hurriedly built in Brooklyn in only 101 days, Monitor presented a new concept in ship design and employed a variety of new inventions and innovations in ship building that caught the attention of the world. The impetus to build Monitor was prompted by the news that the Confederates were building an ironclad warship, named Virginia, that could effectively engage the Union ships blockading Hampton Roads and the James River leading to Richmond and ultimately advance on Washington, D. C. and other cities, and could do so virtually unchallenged. Before Monitor could reach Hampton Roads, the Confederate ironclad had destroyed the sail frigates USS Cumberland and USS Congress and had run the steam frigate USS Minnesota aground. That night Monitor arrived and the following morning, just before Virginia was about to finish off the Minnesota, the new Union ironclad confronted the Confederate ship, preventing her from wreaking further destruction on the wooden Union ships. A four-hour battle ensued, both ships pounding the other with close-range cannon fire, although neither ship could destroy or seriously damage the other. This was the first-ever battle fought between two armored warships and marked a turning point in naval warfare. After the Confederates were forced to destroy Virginia as they withdrew in early May, Monitor sailed up the James River to support the Union Army during the Peninsula Campaign. The ship participated in the Battle of Drewry's Bluff later that month and remained in the area giving support to General McClellan's forces on land until she was ordered to join the blockaders off North Carolina in December. On her way there she foundered while under tow during a storm off Cape Hatteras on the last day of the year. Monitor '​s wreck was discovered in 1973 and has been partially salvaged. Her guns, gun turret, engine and other relics are on display at the Mariners' Museum in Newport News, Virginia. While the concept of ships protected by armor existed before the advent of the ironclad Monitor, the need for iron plating on ships only arose after the shell-firing cannon was introduced to naval warfare in the 1820s. The use of heavy iron plating on the sides of warships was not practical until steam propulsion matured enough to carry its great weight. Developments in gun technology had progressed by the 1840s so that no practical thickness of wood could withstand the power of a shell. In response, the United States began construction in 1854 of a steam-powered ironclad warship, the Stevens Battery, but work was delayed and the designer, Robert Stevens, died in 1856, stalling further work. Since there was no pressing need for such a ship at the time, there was little demand to continue work on the unfinished vessel. It was France that introduced the first operational armored ships as well as the first shell guns and rifled cannons. Experience during the Crimean War of 1854–55 showed that armored ships could withstand repeated hits without significant damage when French ironclad floating batteries defeated Russian coastal fortifications during the Battle of Kinburn. Ericsson claimed to have sent the French Emperor Napoléon III a proposal for a monitor-type design, with a gun turret, in September 1854, but no record of any such submission could be found in the archives of the French Ministry of the Navy (Ministre de la Marine) when they were searched by naval historian James Phinney Baxter III. The French followed those ships with the first ocean-going ironclad, the armored frigate Gloire in 1859, and the British responded with HMS Warrior. The Union Navy's attitude towards ironclads changed quickly when it was learned that the Confederates were converting the captured USS Merrimack to an ironclad at the naval shipyard in Norfolk, Virginia. Subsequently the urgency of Monitor '​s completion and deployment to Hampton Roads was driven by fears of what the Confederate ironclad, now renamed Virginia, would be capable of doing, not only to Union ships but to cities along the coast and riverfronts. Northern newspapers published daily accounts of the Confederates' progress in converting the Merrimack to an ironclad; this prompted the Union Navy to complete and deploy Monitor as soon as possible.
