and as Cumberland listed and began to go down, she almost pulled Virginia under with her. At the time the vessels were locked, one of Cumberland's anchors was hanging directly above the foredeck of Virginia. Had it come loose, the two ships might have gone down together. Virginia broke free, however, her ram breaking off as she backed away. Buchanan next turned Virginia on Congress. Seeing what had happened to Cumberland, Lieutenant Joseph B. Smith, captain of Congress, ordered his ship grounded in shallow water. By this time, the James River Squadron, commanded by John Randolph Tucker, had arrived and joined Virginia in the attack on Congress. After an hour of unequal combat, the badly damaged Congress surrendered. While the surviving crewmen of Congress were being ferried off the ship, a Union battery on the north shore opened fire on Virginia. In retaliation, Buchanan ordered Congress fired upon with hot shot, cannonballs heated red-hot. Congress caught fire and burned throughout the rest of the day. Near midnight, the flames reached her magazine and she exploded and sank, stern first. Personnel losses included 110 killed or missing and presumed drowned. Another 26 were wounded, of whom ten died within days. Although she had not suffered anything like the damage she had inflicted, Virginia was not completely unscathed. Shots from Cumberland, Congress, and Union troops ashore had riddled her smokestack, reducing her already low speed. Two of her guns were disabled and several armor plates had been loosened. Two of her crew were killed, and more were wounded. One of the wounded was Captain Buchanan, whose left thigh was pierced by a rifle shot. Meanwhile, the James River Squadron had turned its attention to Minnesota, which had left Fort Monroe to join in the battle and had run aground. After Virginia had dealt with the surrender of Congress, she joined the James River Squadron despite her damage.

The attack was therefore suspended. Virginia left with the expectation of returning the next day and completing the task. She retreated into the safety of Confederate-controlled waters off Sewell's Point for the night, but had killed 250 enemy sailors and had lost two. The Union had lost two ships and
