In an effort to renew his Peninsular Campaign, General George McClellan requested a squadron to force its way up the James River and threaten Richmond from the water. To fulfill this request, North Atlantic Blockading Squadron commander, Flag Officer Louis Goldsborough, assigned Commodore John Rodgers the command of the James River Squadron, which included the Navy's wooden steam gunboats and , the ironclads USS
Monitor and , and
E.A. Stevens. The Federal warships experienced only minor resistance during their passage up the
James River to reach the fortifications at Drewry's Bluff. On May 15, the battle opened when Rodgers' flagship
Galena approached to within of sunken obstructions in the river. The fort was armed with eight heavy naval guns, manned by local Confederate land forces and naval personnel (the former crew of the
Virginia).
Galena received over forty hits, of which eighteen penetrated its armor.
Stevens also moved up to take its place in the battle. The gunboat's technological innovations worked effectively, and she sustained no heavy damage from plunging fire as it sat partly submerged and firing its main battery. Moreover, the gunboat's ordnance loading system successfully protected the crew from enemy sharpshooters and musket fire.
Stevens bombardment halted when the 100-pound Parrott rifle burst while firing. The explosion shattered the gun's breech, damaging the pilothouse and the ship's deck. Despite losing its main gun, the gunboat continued to fire its 12-pound howitzers with canister and shell. By 11 a.m.,
Galena had suffered severe damage, exhausted her ammunition, and sustained thirteen dead and many wounded. Rodgers ordered the fleet to retire down river.
Stevens had experienced few casualties despite musket fire, enemy shelling, and her catastrophic gun failure. One of the crew received a shot in the arm; another suffered a serious contusion. Lieutenant Constable sustained a head injury from shrapnel from the exploding Parrott gun, but remained at his station directing the broadside guns and commanding the ship throughout the remainder of the battle. The James River Squadron retired to City Point, with
Stevens arriving that evening and the rest of the squadron arriving in the morning of May 16. On the 16th, Rodgers convened a board, composed of squadron officers, to examine the remains of the Parrott rifle and determine the cause of its failure. The board concluded that rigorous testing and experimentation before installation on board
Stevens had weakened the gun, which was the first of its kind produced by the manufacturer. Meanwhile, the gunboat received the squadron's wounded and proceeded downriver shortly thereafter to Fort Monroe.
E.A. Stevens had been operating in Virginia waters since early April 1862. Even though her main gun remained shattered, Commodore Rodgers still felt it could provide good service to the James River Squadron. Nevertheless, the vessel saw no serious action after Drewry's Bluff. ==Returned to the Treasury Department==
