The vessel was a new kind of warship, an all-steam powered "iron-clad". In the centuries-old tradition of reusing captured ships, the new warship was christened CSS "Virginia". She later fought the Unions new ironclad USS "Monitor". On the second day of the Battle of Hampton Roads, the two ships met and each scored numerous hits on the other. On the first day of that battle "Virginia", and the James River Squadron, aggressively attacked and nearly broke the Union Navys sea blockade of wooden warships, proving the effectiveness of the ironclad concept. The two ironclads had steamed forward, tried to outflank or ram the other, circled, backed away, and came forward firing again and again, but neither was able to sink or demand surrender of its opponent. After four hours, both ships were taking on water through split seams and breaches from enemy shot. The engines of both ships were becoming dangerously overtaxed, and their crews were near exhaustion. The two ships turned and steamed away, never to meet again. This part in the Battle of Hampton Roads between "Monitor" and "Virginia" greatly overshadowed the bloody events each side's ground troops were fighting, largely because it was the first battle in history between two iron-armored steam-powered warships.
