The third USS Dolphin was the brig in the United States Navy. Her plans were the basis of other brigs of that time. She was named for the aquatic mammal.
USS Adams was a 28-gun (rated) sailing frigate of the United States Navy. She was laid down in 1797 at New York City by John Jackson and William Sheffield and launched on 8 June 1799. Captain Richard Valentine Morris took command of the ship.
The second USS Ohio was a ship of the line of the United States Navy, rated at 74 guns, although her total number of guns was 104. She was designed by Henry Eckford, laid down at Brooklyn Navy Yard in 1817, and launched on 30 May 1820. She went into ordinary and in the ensuing years decayed badly. Refitted for service in 1838, Ohio sailed on 16 October 1838 to join the Mediterranean Squadron under Commodore Isaac Hull. Acting as flagship for two years, she protected commerce and suppressed the slave trade off the African coast. Ohio proved to have excellent performance under sail, repeatedly making more than 12 kn. One of her officers stated, "I never supposed such a ship could be built—a ship possessing in so great a degree all the qualifications of a perfect vessel." In 1840, Ohio returned to Boston, where she again went into ordinary. From 1841 to 1846, Ohio served as receiving ship.
The Blockade of Africa began in 1808 after the United Kingdom outlawed the Atlantic slave trade, making it illegal for British ships to transport slaves. The Royal Navy immediately established a presence off Africa to enforce the ban, called the West Africa Squadron. Although the ban initially applied only to British ships, Britain negotiated treaties with other countries to give the Royal Navy the right to intercept and search their ships for slaves.
The first John Adams was originally built in 1799 as a frigate for the United States Navy, converted to a corvette in 1809, and later converted back to a frigate in 1830. Named for American Founding Father and president John Adams, she fought in the Quasi-War, the First and Second Barbary Wars, the War of 1812, the Mexican–American War and the American Civil War. At the end of her career, she participated in the Union blockade of South Carolina's ports.
USS Saratoga, a sloop-of-war, was the third ship of the United States Navy to be named for the Battle of Saratoga of the American Revolutionary War. Her keel was laid down in the summer of 1841 by the Portsmouth Navy Yard. She was launched on 26 July 1842 and commissioned on 4 January 1843 with Commander Josiah Tattnall III in command.
USS Germantown was a United States Navy sloop-of-war in commission for various periods between 1847 and 1860. She saw service in the Mexican–American War in 1847–1848 and during peacetime operated in the Caribbean, in the Atlantic Ocean off Africa and South America, and in East Asia. Scuttled at the outbreak of the American Civil War in 1861, she was captured and refloated by the Confederate States of America and placed in service with the Confederate States Navy as the floating battery CSS Germantown before again being scuttled in 1862.
The third USS Alligator was a schooner in the United States Navy.
The West Africa Squadron, also known as the Preventative Squadron, was a squadron of the British Royal Navy whose goal was to suppress the Atlantic slave trade by patrolling the coast of West Africa. Formed in 1808 after the British Parliament passed the Slave Trade Act 1807 and based out of Portsmouth, England, it remained an independent command until 1856 and then again from 1866 to 1867.
The first USS Truxtun was a brig in the United States Navy. She was named for Commodore Thomas Truxtun, and was an active participant in the Mexican–American War.
USS Nightingale was originally the tea clipper and slave ship Nightingale, launched in 1851. USS Saratoga captured her off Africa in 1861; the United States Navy then purchased her.
USS Perry was a brig commissioned by the United States Navy prior to the American Civil War. She was tasked by the Navy for various missions, including those related to diplomatic tensions with Paraguay, the Mexican–American War, the slave trade, and the American Civil War. She was probably named after Commodore Oliver Hazard Perry.
The third HMS Black Joke was probably built in Baltimore in 1824, becoming the Brazilian slave ship Henriquetta. The Royal Navy captured her in September 1827, and purchased her into the service. The Navy renamed her Black Joke, after an English song of the same name, and assigned her to the West Africa Squadron. Her role was to chase down slave ships, and over her five-year career, she freed thousands of slaves. The Navy deliberately burnt her in May 1832 because her timbers had rotted to the point that she was no longer fit for active service.
Sunny South, an extreme clipper, was the only full-sized sailing ship built by George Steers, and resembled his famous sailing yacht America, with long sharp entrance lines and a slightly concave bow. Initially, she sailed in the California and Brazil trades. Sold in 1859 and renamed Emanuela, she was considered to be the fastest slaver sailing out of Havana. The British Royal Navy captured Emanuela off the coast of Africa in 1860 with over 800 slaves aboard. The Royal Navy purchased her as a prize and converted her into a Royal Navy store ship, Enchantress. She was wrecked in the Mozambique Channel in 1861.
The Capture of the brig Brillante occurred around 1832 and was considered a significant feat in the Blockade of Africa. Brillante was a slave ship that the Royal Navy succeeded in capturing after two failed attempts. The brig had a crew of sixty men and was armed with ten guns. Brillante was under the command of an English-born captain named Homans when she was seized. Homans was an experienced slaver who in ten cruises had landed 5,000 slaves on the coasts of Brazil and Cuba. Brillante reportedly fought at least two battles against the British anti-slavery patrols. She allegedly forced the crew of one British cruiser to abandon ship after a bloody action and on a different occasion, she repulsed boats from a Royal Navy sloop-of-war.
The West Indies Anti-Piracy Operations were a series of military operations and engagements undertaken by the United States Navy against pirates in and around the Antilles. Between 1814 and 1825, the American West Indies Squadron hunted pirates on both sea and land, primarily around Cuba and Puerto Rico. After the capture of Roberto Cofresi in 1825, acts of piracy became rare, and the operation was considered a success, although limited occurrences went on until slightly after the start of the 20th century.
The Ingham Incident, or the Montezuma Affair, was a naval battle fought in 1835, the first between Mexico and the United States. The Mexican warship Montezuma patrolled the coast of Texas to prevent the smuggling of contraband into the territory. During the cruise, the Mexicans captured the American merchant ship Martha and later the Texan ship Columbia which led to a response by the United States Revenue-Marine revenue cutter USRC Ingham. A bloodless engagement was fought on June 14, and ended when the Montezuma was purposely run aground to prevent capture.
Numerous ships have sailed under the name Antelope. Notable ones include:
