USS Alligator, the fourth United States Navy ship of that name, is the first known U.S. Navy submarine, and was active during the American Civil War (the first American underwater vehicle was Turtle during the Revolutionary War, and was operated by the Continental Army, vice Navy, in 1776 against British vessels in New York harbor). During the Civil War the Confederate States Navy would also build its own submarine, H. L. Hunley.
Brutus de Villeroi was a French engineer, inventor, and ship designer. Well-regarded in France where he had designed many diving ships, he immigrated to the United States in 1856, where he continued his work in ship-building. One of his ships was a salvage ship built in 1859. This ship was later retroactively dubbed the "Alligator Junior" (or Alligator Jr.) due to serving as something of a prototype for the Alligator. It was around 30–35 feet long, a mere 44 inches in diameter, iron-hulled, and weighed several tons. It opted to be powered by a small propeller from the start, rather than the paddles and oars used in earlier designs (and the first version of the Alligator). The crew would pull a leather strap from the inside to turn the propeller. In theory, the boat could sail to a location, dive, rest on sea bottom, then release divers to collect nearby sunken salvage. [1]
de Villeroi provided a public demonstration of the boat on October 2, 1859, near Marcus Hook, Pennsylvania, but the salvage ship appears to have been unused afterward, whether due to some unpublicized problem or lack of a financially sound plan to use the ship. At some point in 1861, the boat was moved across the Delaware River to New Jersey, perhaps to dock the boat more cheaply than in the Philadelphia region. de Villeroi seems to have attempted to sell the ship to the US Navy after the Attack on Fort Sumter, but his attempt was apparently ineffective or lost. The ship was reactivated and sailed the Delaware on the night of May 16 and morning of May 17, 1861; it was spotted by the Harbor Police, the two crewmen were arrested, and the ship was impounded at the Noble Street pier in Philadelphia. The crew's claims of the US Navy having arranged the voyage were quickly proven false. The curiosity drew public attention, speculation, and excitement. Commandant Samuel Francis Du Pont decided that the ship was not a threat, and returned it to its owners after an inspection at the Philadelphia Navy Yard. de Villeroi continued to press for the use of his invention, and Du Pont sent three officers to examine the boat on 20 May. Their report in July found the existing ship as not feasible to use as a weapon - it was too slow and operated poorly in inclement weather conditions. de Villeroi offered to sell the ship to the US Navy, but was ignored; he wrote directly to President Lincoln asking that his inventions be given a chance. It was decided that while the old salvage ship was an interesting model but unworkable in practice, a larger and faster diving ship might yet have some potential. [1]
The Alligator Junior seems to have been essentially abandoned afterward; it was probably tied up at the Rancocas Creek in New Jersey, but not maintained. Its position has been lost, although in 2024 a team proposed that they found a deposit of metal that may be the lost ship. [1] [2]
In the autumn of 1861, the Union Navy asked the firm of Neafie & Levy to construct a small submersible ship designed by de Villeroi, who also acted as a supervisor during the first phase of the construction. The boat was about 47 feet (14 m) long, with a beam of 4 feet 8 inches (1.42 m) and height of 5 feet 6 inches (1.68 m). [3] "It was made of iron, with the upper part pierced for small circular plates of glass, for light, and in it were several water tight compartments". She was designed to carry 18 men. For propulsion, she was equipped with 16 hand-powered paddles protruding from the sides. On 3 July 1862, the Washington Navy Yard had the paddles replaced by a hand-cranked propeller, which improved its speed to about four knots. [4] Air was supplied from the surface by two tubes with floats, connected to an air pump located inside the submarine; it was the first operational submarine to have an air purifying system. [5] [3] The boat had a forward airlock, and was the first operational submarine with the capability for a diver to leave and return while both remained submerged. [5] [3] Divers could affix mines to a target, then return and detonate them by connecting the mine's insulated copper wire to a battery inside the vessel. [6]
The Union Navy wanted such a vessel to counter the threat posed to its wooden-hulled blockaders by the former screw frigate Merrimack which, according to intelligence reports, the Norfolk Navy Yard was rebuilding as an ironclad ram for the Confederacy (CSS Virginia). The Union Navy's agreement with the Philadelphia shipbuilder specified that the submarine was to be finished in not more than 40 days; its keel was laid down almost immediately following the signing on 1 November 1861 of a contract for her construction. Nevertheless, the work proceeded so slowly that more than 180 days had elapsed when the novel craft finally was launched on 1 May 1862.
Soon after her launching, she was towed to the Philadelphia Navy Yard to be fitted out and manned. Two weeks later, she was placed under command of a civilian, Mr. Samuel Eakins. On 13 June, the Navy formally accepted the boat.
Next, the steam tug Fred Kopp was engaged to tow the submarine to Hampton Roads, Virginia. The two vessels got underway on 19 June and proceeded down the Delaware River to the Delaware and Chesapeake Canal, through which they entered the Chesapeake Bay for the last leg of the voyage, reaching Hampton Roads on the 23rd. At Norfolk, the submarine was moored alongside the sidewheel steamer USS Satellite, which was to act as her tender during her service with the North Atlantic Blockading Squadron. A spring 1862 newspaper report called the vessel Alligator, in part because of its green color, a moniker which soon appeared in official correspondence. [3]
Several tasks were considered for the vessel: destroying a bridge across Swift Creek, a tributary of the Appomattox River; clearing away the obstructions in the James River at Fort Darling, which had prevented Union gunboats from steaming upstream to support General McClellan's drive up the peninsula toward Richmond; and blowing up CSS Virginia II should that ironclad be completed on time and sent downstream to attack Union forces. Consequently, the submarine was sent up the James to City Point where she arrived on the 25th. Commander John Rodgers, the senior naval officer in that area, examined Alligator and reported that neither the James off Fort Darling nor the Appomattox near the bridge was deep enough to permit the submarine to submerge completely. Moreover, he feared that while his theater of operation contained no targets accessible to the submarine, the Union gunboats under his command would be highly vulnerable to her attacks should Alligator fall into enemy hands. He therefore requested permission to send the submarine back to Hampton Roads.
The ship headed downriver on the 29th and then was ordered to proceed to the Washington Navy Yard for more experimentation and testing. In August, Lt. Thomas O. Selfridge Jr. was given command of Alligator and she was assigned a naval crew. The tests proved unsatisfactory, and Selfridge pronounced "the enterprise ... a failure".
On 3 July 1862, the Navy Yard replaced Alligator's oars with a hand-cranked screw propeller, thereby increasing her speed to about 4 knots (7.4 km/h). President Lincoln observed the submarine in operation on 18 March 1863.
About this time, Rear Admiral Samuel Francis du Pont, who had become interested in the submarine while in command of the Philadelphia Navy Yard early in the war, decided that Alligator might be useful in carrying out his plans to take Charleston, South Carolina, the birthplace of secession. Acting Master John F. Winchester, who then commanded Sumpter, was ordered to tow the submarine to Port Royal, South Carolina. The pair got underway on 31 March.
The next day, both encountered bad weather which, on 2 April, forced Sumpter to cut Alligator adrift off Cape Hatteras. [7] She either immediately sank or drifted for a while before sinking, ending the career of the United States Navy's first submarine. An attempt to find it in 2005 was not successful. [8]
CSS Virginia was the first steam-powered ironclad warship built by the Confederate States Navy during the first year of the American Civil War; she was constructed as a casemate ironclad using the razéed original lower hull and engines of the scuttled steam frigate USS Merrimack. Virginia was one of the participants in the Battle of Hampton Roads, opposing the Union's USS Monitor in March 1862. The battle is chiefly significant in naval history as the first battle between ironclads.
USS Housatonic was a screw sloop-of-war of the United States Navy, taking its name from the Housatonic River of New England.
H. L. Hunley, also known as the Hunley, CSS H. L. Hunley, or CSS Hunley, was a submarine of the Confederate States of America that played a small part in the American Civil War. Hunley demonstrated the advantages and dangers of undersea warfare. She was the first combat submarine to sink a warship (USS Housatonic), although Hunley was not completely submerged and, following her attack, was lost along with her crew before she could return to base. Twenty-one crewmen died in the three sinkings of Hunley during her short career. She was named for her inventor, Horace Lawson Hunley, shortly after She was taken into government service under the control of the Confederate States Army at Charleston, South Carolina.
The Confederate States Navy (CSN) was the naval branch of the Confederate States Armed Forces, established by an act of the Confederate States Congress on February 21, 1861. It was responsible for Confederate naval operations during the American Civil War against the United States's Union Navy.
USS Minnesota was a wooden steam frigate in the United States Navy. Launched in 1855 and commissioned eighteen months later, the ship served in east Asia for two years before being decommissioned. She was recommissioned at the outbreak of the American Civil War and returned to service as the flagship of the North Atlantic Blockading Squadron.
CSS Oregon was a wooden sidewheel steamer that served as a gunboat in the Confederate States Army during the American Civil War. Built in 1846 for the Mobile Mail Line, she transported mail between New Orleans, Louisiana, and Mobile, Alabama, before the war. In 1861, she was seized by the Governor of Louisiana, Thomas Overton Moore, and served as a blockade runner before being selected for use by the Confederate Army. After transferring men and supplies to Ship Island, she was formally converted into a gunboat and armed with four cannon. Remaining behind on Lake Pontchartrain when many Confederate warships were transferred up the Mississippi River, Oregon served in the Mississippi Sound and Pass Christian areas. She took part in several minor actions involving USS New London, two of which resulted in the Confederates moving into shallow water to avoid close-range action, and the third ending when the Confederate ships abandoned the Pass Christian area. In April 1862, Union pressure confined her and other Confederate ships to Lake Pontchartrain. Later that month, with Union forces closing in on New Orleans, Oregon was sunk as a blockship. Her wreck was removed and destroyed in the early 1870s.
The first USS Pawnee was a sloop-of-war in the United States Navy during the American Civil War. She was named for the Pawnee Indian tribe.
USS Merrimack, also improperly Merrimac, was a steam frigate, best known as the hull upon which the ironclad warship CSS Virginia was constructed during the American Civil War. The CSS Virginia then took part in the Battle of Hampton Roads in the first engagement between ironclad warships.
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.
CSS Teaser had been the aging Georgetown, D.C. tugboat York River until the beginning of the American Civil War, when she was taken into the Confederate States Navy and took part in the famous Battle of Hampton Roads. Later, she was captured by the United States Navy and became the first USS Teaser.
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.
Brutus de Villeroi was a French engineer of the 19th century, born Brutus Amédée Villeroi in the city of Tours and soon moved to Nantes, who developed some of the first operational submarines, and the first submarine of the United States Navy, the Alligator, in 1862.
Neafie, Levy & Co., commonly known as Neafie & Levy, was a Philadelphia, Pennsylvania shipbuilding and engineering firm that existed from the middle of the 19th to the beginning of the 20th century. Described as America's "first specialist marine engineers", Neafie & Levy was probably the first company in the United States to combine the building of iron ships with the manufacture of steam engines to power them. The company was also the largest supplier of screw propellers to other North American shipbuilding firms in its early years, and at its peak in the early 1870s was Philadelphia's busiest and most heavily capitalized shipbuilder.
Pioneer was the first of three submarines privately developed and paid for by Horace Lawson Hunley, James McClintock, and Baxter Watson.
USS Satellite was a large, steam-powered large tugboat, acquired by the Union Navy during the American Civil War and equipped with two powerful 8-inch guns. She was assigned to the Union blockade of the Confederate States of America.
USS Yankee was a steam-powered side-wheel tugboat acquired by the Union Navy just prior to the outbreak of the American Civil War.
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.
USS G. W. Blunt was a Sandy Hook pilot boat acquired by the Union Navy during the American Civil War in 1861. See George W. Blunt (1856) for more details. She was used by the Union Navy as a gunboat as well as a dispatch boat in support of the Union Navy blockade of Confederate waterways.
The Sinking of USS Housatonic on 17 February 1864 during the American Civil War was an important turning point in naval warfare. The Confederate States Navy submarine, H.L. Hunley made her first and only attack on a Union Navy warship when she staged a clandestine night attack on USS Housatonic in Charleston harbor. H.L. Hunley approached just under the surface, avoiding detection until the last moments, then embedded and remotely detonated a spar torpedo that rapidly sank the 1,240 long tons (1,260 t) sloop-of-war with the loss of five Union sailors. H.L. Hunley became renowned as the first submarine to successfully sink an enemy vessel in combat, and was the direct progenitor of what would eventually become international submarine warfare, although the victory was Pyrrhic and short-lived, since the submarine did not survive the attack and was lost with all eight Confederate crewmen.
