The very first USS Hatteras was a 1,126-ton iron-hulled steamer purchased by the Union Navy at the beginning of the American Civil War. She was outfitted as a gunboat and assigned to the Union blockade of the ports and waterways of the Confederate States of America. During an engagement with the disguised Confederate commerce raider, CSS Alabama, she was taken by surprise and was sunk off the coast of Galveston, Texas. The wreck site is one of the few listed on the National Register of Historic Places because of its location away from destructive surf and because of the ship's side-wheel design, which marks the transition between wooden sailing ships and steam-powered ships.
CSS Alabama was a screw sloop-of-war built in 1862 for the Confederate States Navy. It was built in Birkenhead on the River Mersey opposite Liverpool, England by John Laird Sons and Company. Alabama served as a successful commerce raider, attacking Union merchant and naval ships over the course of her two-year career. She was sunk in June 1864 by USS Kearsarge at the Battle of Cherbourg outside the port of Cherbourg, France.
Princess Royal was a British merchant ship and blockade runner that became a cruiser in the Union Navy during the American Civil War and later returned to civilian service.
The SS Cornubia was laid down in November 1856 and built in Hayle, Cornwall, by Harvey & Co. She was launched in February 1858 as a packet ship and ferry for the Hayle and Bristol Steam Packet Company. Sleek and painted white, with two funnels mounted close together amidships and with a high bridge over her paddle wheels, she plied the Hayle/St Ives to Bristol route in the days when the Great Western Railway had not penetrated as far as West Cornwall.
USS Fort Jackson was a wooden sidewheel steamer in the United States Navy during the American Civil War. She was successful in enforcing the Union blockade of Confederate ports, capturing five ships carrying contraband. She participated in the battles for Fort Fisher, which effectively closed the port of Wilmington, North Carolina to the Confederacy. Most notably, the surrender of Confederate forces in Texas was signed aboard the ship, formally ending the Civil War in that portion of the country.
CSS Sumter, converted from the 1859-built merchant steamer Habana, was the first steam cruiser of the Confederate States Navy during the American Civil War. She operated as a commerce raider in the Caribbean and in the Atlantic Ocean against Union merchant shipping between July and December 1861, taking eighteen prizes, but was trapped in Gibraltar by Union Navy warships. Decommissioned, she was sold in 1862 to the British office of a Confederate merchant and renamed Gibraltar, successfully running the Union blockade in 1863 and surviving the war.
Harriet Lane was a revenue cutter of the United States Revenue Cutter Service and, on the outbreak of the American Civil War, a ship of the United States Navy and later Confederate States Navy. The craft was named after the niece of senator and later United States President, James Buchanan; during his presidency, she acted as First Lady. The cutter was christened and entered the water for the Revenue Service in 1859 out of New York City, and saw action during the Civil War at Fort Sumter, New Orleans, Galveston, Texas, and Virginia Point. The Confederates captured her in 1863, whereupon she was converted to mercantile service. Union forces recaptured her at the end of war. The U.S. Navy declared her unfit for service and sold her. New owners out of Philadelphia renamed her Elliot Ritchie. Her crew abandoned her at sea in 1881.
The first USS Seminole was a steam sloop-of-war in the United States Navy during the American Civil War.
USS Albatross was a screw steamer rigged as a three-masted schooner acquired by the Union Navy during the beginning of the American Civil War. She was outfitted as a gunboat with heavy guns and used in the Union blockade of the waterways of the Confederate States of America.
USS Santiago de Cuba was a side-wheel steamship acquired by the Union Navy during the first year of the American Civil War. She was outfitted as a gunboat with powerful 20-pounder rifled guns and 32-pounder cannon and was assigned to the Union blockade of the Confederate States of America. She was notably successful in this role, capturing several blockade runners. Her last major action of the war was the assault on Fort Fisher, during which seven of her crew won the Medal of Honor.
The first USS Gettysburg was a steamer in the United States Navy. The ship was built in Glasgow, Scotland, in 1858, named RMS Douglas, and operated by the Isle of Man Steam Packet Company in the United Kingdom between Liverpool, England, and Douglas on the Isle of Man until November 1862. She was then sold to Cunard, Wilson & Company on behalf of the Confederate agents Fraser, Trenholm & Company for use by the Confederate States of America during the American Civil War. Renamed Margaret and Jessie, she operated as a blockade runner until her capture by the Union on 5 November 1863. The ship then was commissioned into the Union Navy on 2 May 1864 as USS Gettysburg.
USS Kennebec was a Unadilla-class gunboat built for the U.S. Navy following the outbreak of the American Civil War. She was named for the Kennebec River.
USS Clifton was a shallow-draft side-wheel paddle steamer, built in 1861 at Brooklyn, as a civilian ferry. The Union Navy bought her early that December, and commissioned her after having her converted into a gunboat. In 1863 she ran aground, was captured and commissioned into the Texas Marine Department. Her career ended in 1864 when she ran aground and her Confederate crew burned her to prevent her recapture.
USS Bienville was a 1,558 long tons (1,583 t) (burden) wooden side-wheel paddle steamer acquired by the Union Navy early in the American Civil War. She was armed with heavy guns and assigned to the Union blockade of the waterways of the Confederate States of America.
USS Connecticut was a large steamer acquired by the Union Navy during the American Civil War. Her primary task was to prevent ships from penetrating the Union blockade of Southern ports.
USS Antona was a steamer captured by the Union Navy during the American Civil War. She was used by the Union Navy as a dispatch boat and gunboat in support of the Union Navy blockade of the Confederate States of America.
USS Gertrude was the British blockade-running steamship Gertrude captured by the Union Navy during the American Civil War. She was placed in service by the Navy as a gunboat and assigned to patrol the southern coast of the United States for ships attempting to run the Union blockade of Southern ports. She was later the American merchant ship Gussie Telfair until wrecked in 1880.
USC&GS Arago was a survey ship that served in the United States Coast Survey from 1854 to 1878 and in the United States Coast and Geodetic Survey from 1878 to 1881. From October 1861 into 1863 Arago was at times attached to the Navy's South Atlantic Blockading Squadron off South Carolina to provide hydrographic support. She was the first ship of the Coast Survey or Coast and Geodetic Survey to bear the name.
During the American Civil War, blockade runners were used to get supplies through the Union blockade of the Confederate States of America that extended some 3,500 miles (5,600 km) along the Atlantic and Gulf of Mexico coastlines and the lower Mississippi River. The Confederacy had little industrial capability and could not indigenously produce the quantity of arms and other supplies needed to fight against the Union. To meet this need, numerous blockade runners were constructed in the British Isles and were used to import the guns, ordnance and other supplies that the Confederacy desperately needed, in exchange for cotton that the British textile industry needed greatly. To penetrate the blockade, these relatively lightweight shallow draft ships, mostly built in British shipyards and specially designed for speed, but not suited for transporting large quantities of cotton, had to cruise undetected, usually at night, through the Union blockade. The typical blockade runners were privately owned vessels often operating with a letter of marque issued by the Confederate government. If spotted, the blockade runners would attempt to outmaneuver or simply outrun any Union Navy warships on blockade patrol, often successfully.
Western Metropolis was a wooden side-wheel steamship built in 1863. She was chartered by the quartermaster corps of the Union Army during the American Civil War to provide logistical support. As a transport ship, she was unarmed, but nonetheless captured a Confederate blockade runner. After the war, she was in commercial service for another ten years. Notably, she made five trans-Atlantic voyages and brought several thousand immigrants to the United States from Northern Europe. She was idled in 1875, and had her engine removed in 1878. Her ultimate fate is unknown.
