USS Patapsco (1862)

Assigned to the South Atlantic Blockading Squadron, she took part in a bombardment of Fort McAllister on 3 March. On 7 April, Patapsco joined eight other ironclads in a vigorous attack on Fort Sumter, and received 47 hits from Confederate gunfire during that day.

Beginning in mid-July, she began her participation in a lengthy bombardment campaign against Charleston's defending fortifications. This led to the capture of Fort Wagner in early September. Fort Sumter was reduced to a pile of rubble, but remained a formidable opponent.

In November 1863, Patapsco tested a large obstruction-clearing explosive device that had been devised by John Ericsson. Remaining off South Carolina and Georgia during much of 1864 and into 1865, the monitor — or her boat crews — took part in a reconnaissance of the Wilmington River, Georgia, in January 1864 and helped capture or destroy enemy sailing vessels in February and November of that year.

On 15 January 1865, while participating in obstruction clearance operations in Charleston Harbor, Patapsco struck a Confederate mine and sank, with 75 lost. The ship's Executive Officer, Lieutenant William T. Sampson was one of a handful of survivors.
