The Battle of Hampton Roads, also referred to as the Battle of the Monitor and Merrimack (rebuilt and renamed as the CSS Virginia) 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 enters Chesapeake Bay adjacent to 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. At least one historian has argued that the Confederacy, rather than trying to break the blockade, was simply trying to take complete control of Hampton Roads in order to protect Norfolk and Richmond.
This battle was significant in that it was the first combat between ironclad warships, the and . The Confederate fleet consisted of the ironclad ram Virginia (built from remnants of the burned steam frigate , newest warship for the United States Navy / Union Navy) 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, Virginia was able to destroy two ships of the federal flotilla, and , and was about to attack a third, , 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.
