Fort Sumter is a sea fort built on an artificial island near Charleston, South Carolina to defend the region from a naval invasion. It was built after British forces captured and occupied Washington during the War of 1812 via a naval attack. The fort was still incomplete in 1861 when the Battle of Fort Sumter occurred, sparking the American Civil War. It was severely damaged during the battle and left in ruins. Although there were some efforts at reconstruction after the war, the fort as conceived was never completed. Since the middle of the 20th century, Fort Sumter has been open to the public as part of the Fort Sumter and Fort Moultrie National Historical Park, operated by the National Park Service.
The first USS Rhode Island was a side-wheel steamer in the United States Navy, commissioned in 1861.
Atlanta was a casemate ironclad that served in the Confederate and Union Navies during the American Civil War. She was converted from a British-built blockade runner named Fingal by the Confederacy after she made one run to Savannah, Georgia. After several failed attempts to attack Union blockaders, the ship was captured by two Union monitors in 1863 when she ran aground. Atlanta was floated off, repaired, and rearmed, serving in the Union Navy for the rest of the war. She spent most of her time deployed on the James River supporting Union forces there. The ship was decommissioned in 1865 and placed in reserve. Several years after the end of the war, Atlanta was sold to Haiti, but was lost at sea in December 1869 on her delivery voyage.
CSS Palmetto State was one of six Richmond class casemate ironclad rams built for the Confederate States Navy during the American Civil War. Completed in 1862, she defended Charleston, South Carolina and was burnt in 1865 to prevent her capture by advancing Union troops.
USS Canonicus was a single-turret monitor built for the United States Navy during the American Civil War, the lead ship of her class. The ship spent most of her first year in service stationed up the James River, where she could support operations against Richmond and defend against a sortie by the Confederate ironclads of the James River Squadron. She engaged Confederate artillery batteries during the year and later participated in both attacks on Fort Fisher, defending the approaches to Wilmington, North Carolina, from December 1864 to January 1865.
CSS Nashville was a brig-rigged, side-paddle-wheel passenger steamer that served with the Confederate Navy during the Civil War.
USS New Ironsides was a wooden-hulled broadside ironclad built for the United States Navy during the American Civil War. The ship spent most of her career blockading the Confederate ports of Charleston, South Carolina, and Wilmington, North Carolina, in 1863–65. New Ironsides bombarded the fortifications defending Charleston in 1863 during the First and Second Battles of Charleston Harbor. At the end of 1864 and the beginning of 1865 she bombarded the defenses of Wilmington in the First and Second Battles of Fort Fisher.
USSKeystone State was a wooden sidewheel steamer that served in the Union Navy during the American Civil War. She was a fast ship for her day and was used effectively to blockade Confederate ports on the Atlantic coast. She participated in the capture or destruction of 17 blockade runners. In addition to her military service, Keystone State had a lengthy commercial career before the war. Renamed San Francisco, she also sailed commercially after the war. The ship was built in 1853 and scrapped in 1874.
USS Wabash was a steam screw frigate of the United States Navy that served during the American Civil War. She was based on the same plans as Colorado. Post-war she continued to serve her country in European operations and eventually served as a barracks ship in Boston, Massachusetts, and was sold in 1912.
The Union blockade in the American Civil War was a naval strategy by the United States to prevent the Confederacy from trading.
The siege of Fort Pulaski concluded with the Battle of Fort Pulaski fought April 10–11, 1862, during the American Civil War. Union forces on Tybee Island and naval operations conducted a 112-day siege, then captured the Confederate-held Fort Pulaski after a 30-hour bombardment. The siege and battle are important for innovative use of rifled guns which made existing coastal defenses obsolete. The Union initiated large-scale amphibious operations under fire.
USS Roanoke was a wooden-hulled Merrimack-class screw frigate built for the United States Navy in the mid-1850s. She served as flagship of the Home Squadron in the late 1850s and captured several Confederate ships after the start of the American Civil War in 1861. The ship was converted into an ironclad monitor during 1862–63; the first ship with more than two gun turrets in history. Her conversion was not very successful as she rolled excessively and the weight of her armor and turrets strained her hull. Her deep draft meant that she could not operate off shallow Confederate ports and she was relegated to harbor defense at Hampton Roads, Virginia for the duration of the war. Roanoke was placed in reserve after the war and sold for scrap in 1883.
USS Mahopac (1864) was a Canonicus-class monitor built for the Union Navy during the American Civil War. The vessel was assigned to the James River Flotilla of the North Atlantic Blockading Squadron upon completion in September 1864. The ship spent most of her time stationed up the James River where she could support operations against Richmond and defend against sorties by the Confederate ironclads of the James River Squadron. She engaged Confederate artillery batteries during the year and later participated in both the first and second battles of Fort Fisher, defending the approaches to Wilmington, North Carolina, in December 1864 – January 1865. Mahopac returned to the James River after the capture of Fort Fisher and remained there until Richmond, Virginia was occupied in early April.
USS Winona was a Unadilla-class gunboat built for service with the Union Navy during the American Civil War. Winona was heavily armed, with large guns for duels at sea, and 24-pounder howitzers for shore bombardment. Winona saw significant action in the Gulf of Mexico and in the waterways of the Mississippi River and was fortunate to return home safely after the war for decommissioning.
USS Dai Ching was a steam gunboat in commissioned into service in the United States Navy in 1863. She served in the Union Navy during the American Civil War until her loss in 1865.
USS Huron was a Unadilla-class gunboat built for the United States Navy during the American Civil War for blockage duty against the ports and rivers of the Confederate States of America.
USS Zouave was a steamer acquired by the Union Navy during the American Civil War. She was needed by the Navy to be part of the fleet of ships to prevent blockade runners from entering ports in the Confederacy.
USS Samuel Rotan was a schooner acquired by the Union Navy during the American Civil War. She was outfitted by the Union Navy as a gunboat to patrol navigable waterways of the Confederacy to prevent the South from trading with other countries. Prior to the war, the US Navy had mostly large, deep-draft, oceangoing vessels. The establishment of the Union blockade required small, fast, shallow-draft vessels like the Samuel Rotan for littoral operations.
USS Isaac Smith was a screw steamer acquired by the United States Navy during the American Civil War. She was used by the Union Navy to patrol navigable waterways of the Confederate States of America to prevent the Confederacy from trading with other countries. In 1863, she became the only warship in the American Civil War to be captured by enemy land forces. She then served in the Confederate States Navy as CSS Stono until she was wrecked.
Siege artillery is heavy artillery primarily used in military attacks on fortified positions. At the time of the American Civil War, the U.S. Army classified its artillery into three types, depending on the gun's weight and intended use. Field artillery were light pieces that often traveled with the armies. Siege and garrison artillery were heavy pieces that could be used either in attacking or defending fortified places. Seacoast artillery were the heaviest pieces and were intended to be used in permanent fortifications along the seaboard. They were primarily designed to fire on attacking warships. The distinctions are somewhat arbitrary, as field, siege and garrison, and seacoast artillery were all used in various attacks and defenses of fortifications. This article will focus on the use of heavy artillery in the attack of fortified places during the American Civil War.
