The _Cumberland_ being utterly demolished, the _Merrimac_ turned her attention to the _Congress_. The Southerners showed their chivalric instincts at this juncture by not firing on the boats, or on a small steamer, which were engaged in picking up the survivors of the _Cumberland’s_ crew. The officers of the _Congress_, seeing the fate of the _Cumberland_, determined that the _Merrimac_ should not, at least, sink their vessel. They therefore got all sail on the ship, and attempted to run ashore. The _Merrimac_ was soon close on them, and delivered a broadside, which was terribly destructive, a shell killing, at one of the guns, every man engaged except one. Backing, and then returning several times, she delivered broadside after broadside at less than 100 yards’ distance. The _Congress_ replied manfully and obstinately, but with little effect. One shot is supposed to have entered one of the ironclad’s port-holes, and dismounted a gun, as there was no further firing from that port, and a few splinters of iron were struck off her sloping mailed roof, but this was all. The guns of the _Merrimac_ appeared to have been specially trained on the after-magazine of the _Congress_, and shot after shot entered that part of the ship. Thus, slowly drifting down with the current, and again steaming up, the _Merrimac_ continued for an hour to fire into her opponent. Several times the _Congress_ was on fire, but the flames were kept under. At length the ship was on fire in so many places, and the flames gathering with such force, that it was hopeless and suicidal to keep up the defence any longer. The national flag was sadly and sorrowfully hauled down, and a white flag hoisted at the peak. The _Merrimac_ did not for a few minutes see this token of surrender, and continued to fire. At last, however, it was discerned through the clouds of smoke, and the broadsides ceased. A tug that had followed the _Merrimac_ out of Norfolk then came alongside the _Congress_, and ordered the officers on board. This they refused, hoping that, from the nearness of the shore, they would be able to escape. Some of the men, to the number, it is believed, of about forty, thought the tug was one of the Northern (Federal) vessels, and rushed on board, and were, of course, soon carried off as prisoners. By the time that all the able men were off ashore and elsewhere, it was seven o’clock in the evening, and the _Congress_ was a bright sheet of flame fore and aft, her guns, which were loaded and trained, going off as the fire reached them. A shell from one struck a sloop at some distance, and blew her up. At midnight the fire reached her magazines, containing five tons of gunpowder, and, with a terrific explosion, her charred remains blew up. Thus had the _Merrimac_ sunk one and burned a second of the largest of the vessels of the enemy.
