The Battle of Hampton Roads, also referred to as the Battle of the Monitor and Merrimack or the Battle of Ironclads, was a naval battle during the American Civil War.
The battle was fought over two days, March 8 and 9, 1862, in Hampton Roads, a roadstead in Virginia where the Elizabeth and Nansemond rivers meet the James River just before it flows into Chesapeake Bay by the city of Norfolk. The battle was a part of the effort of the Confederacy to break the Union blockade, which had cut off Virginia's largest cities and major industrial centers, Norfolk and Richmond, from international trade. This battle was significant in that it was the first combat between ironclad warships, the USS Monitor and CSS Virginia. The Confederate fleet consisted of the ironclad ram Virginia (built from remnants of the burned steam frigate USS Merrimack) and several supporting vessels. On the first day of battle, they were opposed by several conventional, wooden-hulled ships of the Union Navy.
On that day, the Virginia was able to destroy two ships of the Union flotilla, USS Congress and USS Cumberland, and was about to attack a third, USS Minnesota, which had run aground. However, the action was halted by darkness and falling tide, so Virginia retired to take care of her few wounded—which included her captain, Flag Officer Franklin Buchanan—and repair her minimal battle damage.
Determined to complete the destruction of Minnesota, Catesby ap Roger Jones, acting as captain in Buchanan's absence, returned the ship to the fray the next morning, March 9. During the night, however, the ironclad Monitor had arrived and had taken a position to defend Minnesota. When Virginia approached, Monitor intercepted her. The two ironclads fought for about three hours, with neither able to inflict significant damage on the other. The duel ended indecisively, Virginia returning to her home at the Gosport Navy Yard for repairs and strengthening, and Monitor to her station defending Minnesota. The ships did not fight again, and the blockade remained in place.
The battle received worldwide attention, having immediate effects on navies around the world. The preeminent naval powers, Great Britain and France, halted further construction of wooden-hulled ships, and others followed suit. Although Britain and France had been engaged in an iron-clad arms race since the 1830s, the Battle of Hampton Roads signaled a new age of naval warfare had arrived for the whole world. A new type of warship, monitor, was produced on the principle of the original. The use of a small number of very heavy guns, mounted so that they could fire in all directions, was first demonstrated by Monitor but soon became standard in warships of all types. Shipbuilders also incorporated rams into the designs of warship hulls for the rest of the century.
Background
The blockade at Norfolk
On April 19, 1861, shortly after the outbreak of hostilities at Charleston Harbor, US President Abraham Lincoln proclaimed a blockade of ports in the seceded states. On April 27, after Virginia and North Carolina had also passed ordinances of secession, the blockade was extended to include their ports also. Even before the extension, local troops had seized the Norfolk area and threatened the Gosport Navy Yard in Portsmouth. The commandant there, Captain Charles S. McCauley, though loyal to the Union, was immobilized by advice he received from his subordinate officers, most of whom were in favor of secession. Although he had orders from (Union) Secretary of the Navy Gideon Welles to move his ships to Northern ports, he refused to act until April 20, when he gave orders to scuttle the ships in the yard and destroy its facilities.
At least nine ships were burned, among them the screw frigate USS Merrimack. Merrimack burned only to the waterline, however, and her engines were more or less intact. The destruction of the navy yard was mostly ineffective; in particular, the large drydock there was relatively undamaged and soon could be restored. Without firing a shot, the advocates of secession had gained for the South its largest navy yard, as well as the hull and engines of what would be in time its most famous warship. They had also seized more than a thousand heavy guns, plus gun carriages and large quantities of gunpowder.
With Norfolk and its navy yard in Portsmouth, the Confederacy controlled the southern side of Hampton Roads. To prevent Union warships from attacking the yard, the Confederates set up batteries at Sewell's Point and Craney Island, at the juncture of the Elizabeth River with the James. (See map.) The Union retained possession of Fort Monroe, at Old Point Comfort on the Virginia Peninsula. They also held a small man-made island known as the Rip Raps, on the far side of the channel opposite Fort Monroe, and on this island they completed another fort, named Fort Wool. With Fort Monroe went control of the lower Peninsula as far as Newport News.
Forts Monroe and Wool gave the Union forces control of the entrance to Hampton Roads. The blockade, initiated on April 30, 1861, cut off Norfolk and Richmond from the sea almost completely. To further the blockade, the Union Navy stationed some of its most powerful warships in the roadstead. There, they were under the shelter of the shore-based guns of Fort Monroe and the batteries at Hampton and Newport News and out of the range of the guns at Sewell's Point and Craney Island. For most of the first year of the war, the Confederacy could do little to oppose or dislodge them.
Birth of the ironclads
When steam propulsion began to be applied to warships, naval constructors renewed their interest in armor for their vessels. Experiments had been tried with armor during the Crimean War (1853–1856), just prior to the American Civil War, and the British and French navies had each built armored ships and were planning to build others. In 1860 the French Navy commissioned La Gloire, the world's first ocean-going ironclad warship. Great Britain followed a year later with HMS Warrior, the world's first armor-plated iron-hulled warship. The use of armor remained controversial, however, and the United States Navy was generally reluctant to embrace the new technology.
CSS Virginia
When the Civil War broke out in 1861, Confederate Secretary of the Navy Stephen R. Mallory was an early enthusiast for the advantages of armor. As he looked upon it, the Confederacy could not match the industrial North in numbers of ships at sea, so they would have to compete by building vessels that individually outclassed those of the Union. Armor would provide the edge. Mallory gathered about himself a group of men who could put his vision into practice, among them John M. Brooke, John L. Porter, and William P. Williamson.
When Mallory's men searched the South for factories that could build engines to drive the heavy ships that he wanted, they found no place to do it immediately. At the best facility, the Tredegar Iron Works in Richmond, building engines from scratch would take at least a year. Upon learning this, Williamson suggested taking the engines from the hulk of Merrimack, recently raised from the bed of the Elizabeth River. His colleagues promptly accepted his suggestion and expanded it, proposing that the design of their projected ironclad be adapted to the hull. Porter produced the revised plans, which were submitted to Mallory for approval.
On July 11, 1861, the new design was accepted, and work began almost immediately. The burned-out hull was towed into a graving dock that the Union Navy had failed to destroy. During the subsequent conversion process, the plans developed further, incorporating an iron ram fitted to the prow. The remodeled ship's weaponry, in addition to the ram, consisted of 10 guns: six 9 in (230 mm) smooth-bore Dahlgrens, two 6.4 in (160 mm) and two 7 in (180 mm) Brooke rifles. Trials showed that these rifles firing solid shot would pierce up to eight inches of armor plating.
The Tredegar Iron works could produce both solid shot and shell, and since it was believed that Virginia would face only wooden ships, she was given only the explosive shell. The armor plating, originally meant to be 1 in (25 mm) thick, was replaced by double plates, each 2 in (51 mm) thick, backed by 24 in (61 cm) of iron and pine. The armor was pierced for 14 gunports: four on each broadside, three forward, and three aft. The revisions, together with the usual problems associated with the transportation system of the South, resulted in delays that pushed out the launch date until February 3, 1862, and she was not commissioned until February 17, bearing the name CSS Virginia.
USS Monitor
Intelligence that the Confederates were working to develop an ironclad caused consternation for the Union, but Secretary of the Navy Gideon Welles waited for Congress to meet to request permission to consider building armored vessels; Congress gave this permission on August 3, 1861. Welles appointed a commission, which became known as the Ironclad Board, of three senior naval officers to choose among the designs that were submitted for consideration. The three men were Captains Joseph Smith, Hiram Paulding, and Commander Charles Henry Davis. The board considered seventeen designs, and chose to support three. The first of the three to be completed, even though she was by far the most radical in design, was Swedish engineer and inventor John Ericsson's USS Monitor.
Ericsson's Monitor, which was built at Ericsson's yard on the East River in Greenpoint, Brooklyn, incorporated new and striking design features, the most significant of which were her armor and armament. Instead of the large numbers of guns of rather small bore that had characterized warships in the past, Ericsson opted for only two guns of large caliber; he wanted to use 15 in (380 mm) guns, but had to settle for 11 in (280 mm) Dahlgren guns when the larger size were unavailable. These were mounted in a cylindrical turret, 20 ft (6.1 m) in diameter, 9 ft (2.7 m) high, covered with iron 8 in (200 mm) thick. The whole rotated on a central spindle, and was moved by a steam engine that could be controlled by one man. Ericsson was afraid that using the full 30 pounds of black powder to fire the huge cannon would raise the risk of an explosion in the turret. He demanded that a charge of 15 pounds be used to lessen this possibility.
As with Virginia, trials found that a full charge would pierce armor plate, a finding that would have affected the outcome of the battle. A serious flaw in the design was the pilot house from which the ship would be conned, a small structure forward of the turret on the main deck. Its presence meant that the guns could not fire directly forward, and it was isolated from other activities on the ship. Despite the late start and the novelty of construction, Monitor was actually completed a few days before her counterpart Virginia, but the Confederates activated Virginia first.
Battle
Command
The Confederate chain of command was anomalous. Lieutenant Catesby ap Roger Jones had directed much of the conversion of Merrimack to Virginia, and he was disappointed when he was not named her captain. Jones was retained aboard Virginia, but only as her executive officer. Ordinarily, the ship would have been led by a captain of the Confederate States Navy, to be determined by the rigid seniority system that was in place. Secretary Mallory wanted the aggressive Franklin Buchanan, but at least two other captains had greater seniority and had applied for the post. Mallory evaded the issue by appointing Buchanan, head of the Office of Orders and Detail, flag officer in charge of the defenses of Norfolk and the James River. As such, he could control the movements of Virginia. Technically, therefore, the ship went into the battle without a captain.
On the Union side, command of the North Atlantic Blockading Squadron was held by Flag Officer Louis M. Goldsborough. He had devised a plan for his frigates to engage Virginia, hoping to trap her in their crossfire. In the event, his plan broke down completely when four of the ships ran aground (one of them intentionally) in the confined waters of the roadstead. On the day of battle, Goldsborough was absent with the ships cooperating with the Burnside Expedition in North Carolina. In his absence, leadership fell to his second in command, Captain John Marston of USS Roanoke. As Roanoke was one of the ships that ran aground, Marston was unable to materially influence the battle, and his participation is often disregarded. Most accounts emphasize the contribution of the captain of Monitor, John L. Worden, to the neglect of others. Marston did, however, disregard orders from Secretary of War Gideon Welles to send the Monitor back to Washington, D.C., ahead of the battle, ensuring that it would be present to confront the Merrimack.
March 8: Virginia wreaks havoc on wooden Union warships
The battle began when the large and unwieldy CSS Virginia steamed into Hampton Roads on the morning of March 8, 1862. Captain Buchanan intended to attack as soon as possible. Virginia was accompanied from her moorings on the Elizabeth River by Raleigh and Beaufort, and was joined at Hampton Roads by the James River Squadron, Patrick Henry, Jamestown, and Teaser. When they were passing the Union batteries at Newport News, Patrick Henry was temporarily disabled by a shot in her boiler that killed four of her crew. After repairs, she returned and rejoined the others.
At this time, the Union Navy had five warships in the roadstead, in addition to several support vessels. The sloop-of-war Cumberland and frigate Congress were anchored in the channel near Newport News. The sail frigate St. Lawrence and the steam frigates Roanoke and Minnesota were near Fort Monroe, along with the storeship Brandywine. The latter three got under way as soon as they saw Virginia approaching, but all soon ran aground. St. Lawrence and Roanoke took no further important part in the battle.
Virginia headed directly for the Union squadron. The battle opened when Union tug Zouave fired on the advancing enemy, and Beaufort replied. This preliminary skirmishing had no effect. Virginia did not open fire until she was within easy range of Cumberland. Return fire from Cumberland and Congress bounced off the iron plates without penetrating, although later some of Cumberland's gunfire lightly damaged Virginia.
Virginia rammed Cumberland below the waterline and she sank rapidly, "gallantly fighting her guns as long as they were above water," according to Buchanan. She took 121 seamen down with her; those wounded brought the casualty total to nearly 150.
