board and capture the vessel, and disable her by using heavy hammers to drive iron wedges under and disable the turret, and by covering the pilothouse with a wet sail effectively blinding the pilot. Others would throw combustibles down the ventilation openings and smoke holes. At one point Jones made such an attempt to board the vessel, but she managed to slip away around the stern of Virginia in time. There was a second confrontation on 8 May, when Virginia came out while Monitor and four other Federal ships bombarded Confederate batteries at Sewell's Point. The Federal ships retired slowly to Fort Monroe, hoping to lure Virginia into the Roads. She did not follow, however, and after firing a gun to windward as a sign of contempt, anchored off Sewell's Point. Later, when Confederate forces abandoned Norfolk on 11 May 1862, they were forced to destroy Virginia. Battle of Drewry's Bluff After the destruction of Virginia, Monitor was free to assist the Union Army and General McClellan's campaign against Richmond. As the Navy always gave command to officers based on seniority, Greene was replaced with Lieutenant Thomas O. Selfridge the day after the battle. Two days later, Selfridge was in turn relieved by Lieutenant William Nicholson Jeffers on 15 May 1862.Fuller, 2008, p. 178 Monitor was now part of a flotilla under the command of Admiral John Rodgers aboard Galena, and, along with three other gunboats, steamed up the James River and engaged the Confederate batteries at Drewry's Bluff. The force had instructions to coordinate their efforts with McClellan's forces on land and push on towards Richmond to bombard the city into surrender if possible. Without any assistance, the task force got within of the Confederate capital but could not proceed further because of sunken vessels and debris placed in the river that blocked further passage. There were also artillery batteries at Fort Darling overlooking and guarding the approach, along with other heavy guns and sharpshooters positioned along the river banks. The fort was strategically situated on the west bank of the James River atop of a bluff some above and overlooking the bend in the river.Stern, 1962, p. 90 Monitor was of little help in the assault because the confinement and small gun ports of her turret would not allow her to elevate her guns sufficiently to engage the Confederate batteries at close range, so she had to fall
