CSS Virginia

**CSS *Virginia*** was the first steam-powered ironclad warship built by the Confederate States Navy during the American Civil War. Converted from the scuttled hull of the Union frigate USS Merrimack, she is best known for her clash with the USS Monitor in the Battle of Hampton Roads on March 8–9, 1862, the first engagement between ironclad warships in history. Although her active career lasted only a few weeks, Virginia revolutionized naval warfare by demonstrating the obsolescence of wooden warships and inaugurating the era of armored naval combat.

Background and Conversion

When Virginia seceded from the Union in April 1861, the Gosport Navy Yard in Portsmouth, Virginia, was hurriedly abandoned by Federal forces. Among the vessels left behind was the 40-gun steam frigate USS Merrimack, which was set on fire and scuttled to prevent capture. Confederate forces quickly raised the hull, discovering that the lower hull and machinery were largely intact. Stephen R. Mallory, the Confederate Secretary of the Navy, seized upon the idea of converting the burned vessel into an ironclad ram, believing that a handful of armored ships could break the Union blockade of Southern ports.

Work began in earnest during the summer of 1861 under the supervision of naval constructor John L. Porter and chief engineer William P. Williamson. The original upper hull above the waterline was cut away, and a massive armored casemate was built over the remaining lower hull. The conversion was carried out at the Gosport Navy Yard, later renamed the Norfolk Navy Yard, using materials and guns salvaged from the yard and from other captured ships. The vessel was rechristened CSS Virginia in February 1862.

Design and Construction

Virginia embodied a radical departure from traditional warship design. Her most distinctive feature was a large, sloping casemate built over the main deck, which housed her battery of guns. The casemate sides were angled at approximately 35 degrees to deflect incoming shot. It was constructed of 24 inches of oak and pine backing, covered by two layers of iron plate, each 2 inches thick, giving a total armor thickness of 4 inches. The iron was procured from the Tredegar Iron Works in Richmond.

The vessel was 275 feet long overall, with a beam of 51 feet and a draft of 22 feet, making her unwieldy in shallow waters. She was propelled by a pair of horizontal direct-acting steam engines that had belonged to Merrimack, driving two screw propellers. This machinery, damaged by fire and saltwater immersion, was never fully reliable, limiting Virginia to a top speed of only about 5–6 knots. A 1,500-pound cast-iron ram was fitted to the bow below the waterline as a primary offensive weapon, reflecting pre-war naval theories that ramming would become decisive in steam combat.

Armament

Virginia carried a mixed battery of ten guns arranged to fire through narrow gunports in the casemate: four single-banded Brooke rifles (two 7-inch and two 6.4-inch) on pivot mounts, and six 9-inch Dahlgren smoothbores in broadside positions. The Brooke rifles were among the most powerful naval ordnance of the era, capable of firing both solid shot and explosive shells. Two of the rifles were mounted to fire directly ahead or astern through corner ports. In addition to her guns and ram, the ship carried a small detachment of Confederate Marines for boarding actions and sharpshooting.

Battle of Hampton Roads

First Day (March 8, 1862)

On March 8, 1862, under the command of Flag Officer Franklin Buchanan, CSS Virginia made her combat debut by descending the Elizabeth River from Norfolk into Hampton Roads, where a Union blockading squadron lay at anchor off Newport News. The wooden frigates USS Cumberland and USS Congress, along with the steam frigate USS Minnesota and several smaller vessels, were caught largely unprepared.

Virginia first attacked the sloop-of-war USS Cumberland, deliberately ramming her under the starboard bow. The iron ram crushed Cumberland’s timbers, and despite the Confederate ship temporarily becoming stuck and almost being dragged down with her victim, the ram broke free. Cumberland sank rapidly, her crew gallantly maintaining fire until the water reached the gun deck. Virginia then turned her attention to USS Congress, which had run aground trying to escape. Taking a raking position, Virginia pounded Congress with shot and shell until the Union ship, ablaze and with heavy casualties, was forced to strike her colors. Buchanan was wounded by musket fire during the engagement, and command passed to Lieutenant Catesby ap Roger Jones.

As darkness fell, the Confederate ironclad withdrew, intending to finish off the grounded steam frigate USS Minnesota the next morning. The first day of battle resulted in the loss of two major Union warships, more than 240 Union sailors killed, and a psychological shock throughout the North.

Second Day (March 9, 1862) – First Battle of Ironclads

During the night, the revolutionary Union ironclad USS Monitor arrived under the command of Lieutenant John L. Worden. Monitor’s low-freeboard, rotating turret design contrasted sharply with Virginia’s casemate. On the morning of March 9, Virginia returned to attack Minnesota, but was intercepted by Monitor. The two ironclads then fought a close-range, hours-long contest that forever changed naval warfare.

They pounded each other at ranges varying from a few dozen yards to over a hundred. The shot and shell of each failed to penetrate the other’s armor, though Virginia’s smokestack was riddled and Monitor’s pilothouse was struck, temporarily blinding and wounding Worden. Virginia attempted to ram Monitor, but the more agile Union vessel evaded and had lost its own ram earlier. Virginia’s crew experimented with firing solid shot, heated shot, and even concentrated broadsides, but nothing could decisively disable the “cheesebox on a raft.” After several hours of maneuvering in the shallow waters, Virginia retired toward Norfolk, and Monitor held the roadstead. The battle was tactically inconclusive but a strategic Union victory, as the blockade remained intact.

Subsequent Operations

After the battle, Virginia was dry-docked at Norfolk for repairs and modifications. She received improved armor over vulnerable areas, a better-protected pilothouse, and additional rifled guns. She ventured into Hampton Roads several times in April, hoping to draw Monitor into a rematch, but the Union ironclad, under strict orders not to risk battle except to defend the blockade, refused to engage on terms favorable to the Confederates. Virginia’s deep draft and weak engines severely limited her ability to operate in the rivers or to challenge the main Union fleet outside the Roads.

Destruction and Legacy

When the Confederate evacuation of Norfolk became inevitable in early May 1862, CSS Virginia faced a critical dilemma. Her draft was too deep to escape up the James River toward Richmond, and she could not survive a voyage into the open sea against the blockading fleet. Lieutenant Jones, now in command, attempted to lighten the ship for passage upriver by jettisoning stores and coal, but the pilot determined it was impossible. To prevent her capture, Virginia was set afire and destroyed by her own crew off Craney Island on May 11, 1862. The flames ignited her powder magazines, and the ship exploded and sank.

The legacy of CSS Virginia is profound. Her brief but violent career demonstrated emphatically that wooden warships were obsolete against armored vessels. The dramatic duel with USS Monitor captured the world’s attention and spurred navies globally to accelerate ironclad programs. The wreck of Virginia remained on the bottom of the Elizabeth River until portions were raised and salvaged in the late 19th century. Artifacts, including one of her anchors, a cannon, and fragments of armor, are preserved in museums such as The Mariners’ Museum in Newport News and the Hampton Roads Naval Museum. CSS Virginia remains a symbol of Southern technological innovation and a pivotal actor in the revolution at sea.
