In naval terminology, a destroyer is a fast, maneuverable, long-endurance warship intended to escort larger vessels in a fleet, convoy, or carrier battle group and defend them against a wide range of general threats. They were originally conceived in 1885 by Fernando Villaamil for the Spanish Navy as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War.
USS Bennington was a member of the Yorktown class of steel-hulled, twin-screw gunboats in the United States Navy in the late 19th and early 20th centuries. She was the first U.S. Navy ship named in honor of the town of Bennington, Vermont, site of the Battle of Bennington in the American Revolutionary War.
USS Agamenticus was one of four Miantonomoh-class monitors built for the United States Navy during the American Civil War. Commissioned as the war was ending in May 1865, the ironclad saw no combat and was decommissioned in September and placed in reserve. The ship was reactivated in 1870, having been renamed Terror the previous year, and was assigned to the North Atlantic Fleet where she served in the Caribbean Sea. The monitor was decommissioned again in 1872 and was sold for scrap two years later. The Navy Department evaded the Congressional refusal to order new ships by claiming that the Civil War-era ship was being repaired while building a new monitor of the same name.
USS Galena was a wooden-hulled broadside ironclad built for the United States Navy during the American Civil War. The ship was initially assigned to the North Atlantic Blockading Squadron and supported Union forces during the Peninsula Campaign in 1862. She was damaged during the Battle of Drewry's Bluff because her armor was too thin to prevent Confederate shots from penetrating. Widely regarded as a failure, Galena was reconstructed without most of her armor in 1863 and transferred to the West Gulf Blockading Squadron in 1864. The ship participated in the Battle of Mobile Bay and the subsequent Siege of Fort Morgan in August. She was briefly transferred to the East Gulf Blockading Squadron in September before she was sent to Philadelphia, Pennsylvania for repairs in November.
USS Onondaga was an ironclad monitor built for the Union Navy during the American Civil War. Commissioned in 1864, the ship spent her entire active career with the James River Flotilla covering the water approaches to the Confederate States capital of Richmond, Virginia, although her only notable engagement was the Battle of Trent's Reach. After the war, she was purchased by France where she served as a coastal defense ship in the French Navy.
USS Yorktown was lead ship of her class of steel-hulled, twin-screw gunboats in the United States Navy in the late 19th and early 20th centuries. She was the second U.S. Navy ship named in honor of the American Revolutionary War's Battle of Yorktown.
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.
USS Saugus was a single-turreted 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 April 1864. The ship spent most of her time 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, in December 1864 – January 1865. Saugus returned to the James River after the capture of Fort Fisher and remained there until Richmond, Virginia, was occupied in early April.
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 Neosho, the lead ship of her class, was an ironclad river monitor laid down for the Union Navy in the summer of 1862 during the American Civil War. After completion in mid-1863, the ship spent time patrolling the Mississippi River against Confederate raids and ambushes as part of Rear Admiral David Porter's Mississippi Squadron. She participated in the Red River Campaign in March–May 1864. Neosho resumed her patrols on the Mississippi after the end of the campaign. She supported the Union Army's operations on the Cumberland River and provided fire support during the Battle of Nashville in December 1864. Neosho was decommissioned after the war and remained in reserve until sold in 1873.
USS Ozark was a single-turreted river monitor built for the United States Navy during the American Civil War. The ship served in the Mississippi River Squadron during the war, and participated in the Red River Campaign shortly after she was commissioned in early 1864. Ozark patrolled the Mississippi River and its tributaries after the end of the campaign for the rest of the war. She was decommissioned after the war and sold in late 1865.
USS Tonawanda was one of four Miantonomoh-class monitors built for the United States Navy during the American Civil War of 1861–1865. Commissioned in 1865 after the war ended in May, the ship was decommissioned at the end of the year, but was reactivated to serve as a training ship at the United States Naval Academy in 1866. She was renamed Amphitrite in 1869 and was decommissioned again in 1872. The monitor was sold for scrap the following year. The Navy Department evaded the Congressional refusal to order new ships by claiming that the Civil War-era ship was being repaired while building a new monitor of the same name.
HMS Audacious was the lead ship of the Audacious-class ironclads built for the Royal Navy in the late 1860s. They were designed as second-class ironclads suitable for use on foreign stations and the ship spent the bulk of her career on the China Station. She was decommissioned in 1894 and hulked in 1902 for use as a training ship. The ship was towed to Scapa Flow after the beginning of the First World War to be used as a receiving ship and then to Rosyth after the war ended. Audacious was sold for scrap in 1929.
USS Concord was a member of the Yorktown class of steel-hulled, twin-screw gunboats in the United States Navy in the late 19th and early 20th centuries. She was the second U.S. Navy ship named in honor of the town of Concord, Massachusetts, site of the Battle of Concord in the American Revolutionary War.
The Denver-class cruisers were a group of six protected cruisers in service with the United States Navy from 1903 through 1929. Authorized by Congress in 1899 as part of the naval buildup touched off by the Spanish–American War, they were designed with peacetime duties on foreign stations and tropical service in mind, specifically patrolling Latin America and the Caribbean. However, they had insufficient armament, armor, and speed for combat with most other cruisers. Thus, they were also called "peace cruisers" and were effectively gunboats. They were intended to augment the Montgomery class in these roles.
The Neosho-class monitors were a pair of ironclad river monitors laid down in mid-1862 for the United States Navy during the American Civil War. After completion in mid-1863, both ships spent time patrolling the Mississippi River against Confederate raids and ambushes as part of Rear Admiral David Porter's Mississippi Squadron. Both ships participated in the Red River Campaign in March–May 1864, although Osage supported the capture of Fort DeRussy in March and participated in the Battle of Blair's Landing in April. Osage was grounded on a sandbar for six months after the end of the campaign while Neosho resumed her patrols on the Mississippi. The latter ship supported the Union Army's operations on the Cumberland River and provided fire support during the Battle of Nashville in December.
The Milwaukee-class monitors were a class of four riverine ironclad monitors built during the American Civil War. Several supported Union forces along the Mississippi River in mid-1864 before participating in the Battle of Mobile Bay in August. Chickasaw and Winnebago bombarded Confederate coastal fortifications during the battle and during subsequent operations as well as engaging the ironclad Tennessee II. The other two ships arrived at Mobile Bay after the battle and all four supported the land attacks on Mobile in March–April 1865. Milwaukee struck a torpedo during this time and sank. The surviving three ships were sold in 1874; Chickasaw was converted into a ferry and survived until 1944 when she was scuttled. Her wreck was discovered in 2004.
The Montgomery-class cruisers were three unprotected cruisers built for the United States Navy in the early 1890s. They had a thin water-tight protective deck, and also relied for protection upon their coal bunkers, cellulose packing, and numerous compartments. Roomy accommodations were provided for officers and crew, these cruisers being mainly intended for long cruises on distant stations.
The Asheville-class gunboat was a class of two gunboats, USS Tulsa and USS Asheville, which was based on Sacramento, an earlier gunboat. Laid down between 1917 and 1919, construction was completed in the early 1920s after which both ships were employed to project US naval power across several different theaters, including Central America and the Pacific, during the interwar years. Tulsa principally served in Asia, assigned variously with the South China Patrol, Yangtze Patrol, and the Inshore Patrol; Asheville mostly stayed in Central America, but did spend a few years on the South China Patrol alongside Tulsa. When war broke out with Japan in the Pacific, both ships were used to escort convoys. Asheville was lost during the war, but Tulsa survived to be broken up in the late 1940s. The class was awarded a total of three battle stars, one for Asheville and two for Tulsa.
