Richmond departed New Orleans on 30 July 1863 for a much-needed overhaul at New York Navy Yard. On 12 October 1863, she sailed south, calling at
Port Royal, South Carolina, and
Key West, Florida, before rejoining Admiral Farragut's squadron at New Orleans on 1 November; a fortnight later she began blockade duty off
Mobile, Alabama. in 1864
Richmond was present with Farragut's fleet when the epic naval assault against Mobile Bay was mounted on 5 August 1864. For this attack,
Richmond was lashed to the starboard side of , and proceeded with the fleet across the bar.
Fort Morgan opened fire and the action was soon general. Fifteen minutes later as the
monitors were preparing to meet the defending Confederate casemate ram , struck a moored "torpedo" or mine and sank in seconds. Then , just ahead of
Richmond, backed athwart ''Richmond's
bow in order to clear "a row of suspicious looking buoys." Richmond
and Port Royal
in turn went hard astern, causing the entire line of wooden ships to fall into disarray. Admiral Farragut in Hartford
decided the boldest course through the torpedo fields was the only one possible and gave his famous command "Damn the torpedoes ... full speed ahead!" Moving into the bay, Richmond
opened fire on the Confederate steamers , , , and Tennessee
. At the same time the gunboat , cast off from Hartford
, captured Selma
. Soon afterward Port Royal
was sent after the disabled Gaines''.
Tennessee attempted in vain to ram
Brooklyn. Capable of only a very small speed, the southern ram was subjected to heavy fire from
Hartford and
Richmond.
Tennessee passed astern toward Fort Morgan as Farragut's fleet proceeded into the bay away from the fort's fire.
Tennessees commander,
Franklin Buchanan, chose to follow and engaged the entire Union squadron. Farragut attacked her with his strongest ships.
Richmond proceeded in line abreast with
Hartford and
Brooklyn. For over an hour the Confederate ship was battered and even rammed by
Hartford. By mid morning, Buchanan could see that his ship was a floating hulk and was surrounded by much stronger forces. Accordingly, a white flag was raised and the twin-turret monitor went alongside.
Richmond suffered no casualties in the action and only slight damage. Fort Morgan still put up determined resistance, however, and
Richmond joined the squadron in a steady day and night bombardment. Invested by Union troops ashore, the fort finally capitulated on 23 August.
Richmond continued to operate in Mobile Bay and also in Pensacola Bay for a time before arriving at the Southeast Pass of the Mississippi River on 23 April 1865. That same evening, the Confederate ram dashed down river from the Red River in an attempt to reach the open sea. Successfully passing Union ships at the mouth of the Red River and at New Orleans,
Webb ran out of luck some below New Orleans. Closely pursued by Union gunboats behind her,
Webb found
Richmond guarding the estuary leading to the Gulf of Mexico. Trapped,
Webb was run ashore, set afire, and blown up by her crew. A total of 33 sailors and marines earned the
Medal of Honor while serving aboard
Richmond during the Civil War, more than on any other ship. The first medals went to four members of the ship's engineering department for their efforts after an engine room was damaged by shellfire during the 14 March 1863 attack on Port Hudson. The remaining medals went to three marines and twenty-six sailors for their actions at the Battle of Mobile Bay. ;Attack on Port Hudson, 14 March 1863 • Second Class Fireman
