A spar torpedo is a weapon consisting of a bomb placed at the end of a long pole, or spar, and attached to a boat. The weapon is used by running the end of the spar into the enemy ship. Spar torpedoes were often equipped with a barbed spear at the end, so it would stick to wooden hulls. A fuse could then be used to detonate it.
Robert Fulton had written about submarine (i.e., subsurface) marine torpedoes in 1810, [1] and experiments were conducted using spar torpedoes that year. [2] Boats carrying spar torpedoes were used during the War of 1812. [3]
E. C. Singer, a private engineer who worked on secret projects for the benefit of the Confederate States of America, constructed a spar torpedo during the American Civil War. His torpedo was detonated by means of a trigger mechanism adapted from a rifle lock (see flintlock mechanism for a similar device). The spring-loaded trigger [4] was detonated by means of a long cord attached to the attacking vessel. The attacking vessel rammed its target, embedding the barbed torpedo in its hull, then backed off. When the attacker reached the limit of the trigger cord, the torpedo was detonated.
Perhaps the most famous use of spar torpedoes during the U.S. Civil War was by the Confederate submarine H. L. Hunley , which managed to sink the Union screw sloop USS Housatonic on February 17, 1864, although the Hunley was lost. Spar torpedoes were also used by the David-class of semi-submersible attack boats. In April 1864, Confederate torpedo boat CSS Squib employed a spar torpedo against USS Minnesota. [5] [6]
At night on October 27–28, 1864, Lieutenant Cushing employed a spar torpedo to sink the Confederate ironclad ram CSS Albemarle. The sinking of the Albemarle was the Union navy's only successful sinking of a Confederate vessel by torpedo. Lieutenant Cushing employed a spar torpedo designed by John Lay.
The semi-submersible 1864 Union craft USS Spuyten Duyvil employed a spar torpedo, but not with a barbed attachment to the target. Owing to an innovative directable and extensible spar, this craft could release a slightly buoyant mine underneath the target, which would be exploded by the means described above. (This craft was not employed against Confederate targets, but was used to clear wreckage from rivers.)
Spar torpedoes were also used on small wooden launches in the late 19th century, although they were not very useful weapons. The locomotive torpedo (the contemporary term for the modern self-propelled torpedo) replaced the spar torpedo as a weapon for submarines and small boats in the 1870s.
Spar torpedoes were also used by Romanian forces during the country's war of independence. On May 26, 1877, the craft Rândunica sank the Ottoman river monitor Seyfi on the Danube. [7]
French admiral Courbet made good use of two spar torpedo boats at the Battle of Fuzhou on August 23, 1884, which sank the flagship of the Chinese Fujian Fleet - corvette Yangwu and a gunboat Fuxing. It showed that spar torpedoes can be effective against ships at anchor, not protected by torpedo nets and without a proper look-out. [8] On February 14, 1885, Courbet also sank Chinese frigate Yuyuan in Battle of Shipu with two spar torpedo boats.
Spar torpedoes were superseded by the automotive torpedo.
A torpedo boat is a relatively small and fast naval ship designed to carry torpedoes into battle. The first designs were steam-powered craft dedicated to ramming enemy ships with explosive spar torpedoes. Later evolutions launched variants of self-propelled Whitehead torpedoes.
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.
CSS Albemarle was a steam-powered casemate ironclad ram of the Confederate Navy, named for an estuary in North Carolina which was named for General George Monck, the first Duke of Albemarle and one of the original Carolina Lords Proprietor.
William Barker Cushing was an officer in the United States Navy, best known for sinking the CSS Albemarle during a daring nighttime raid on 27 October 1864, for which he received the Thanks of Congress. Cushing was the younger brother of Medal of Honor recipient Alonzo Cushing. As a result, the Cushing family is the only family in American history to have a member buried at more than one of the United States Service Academies.
Horace Lawson Hunley was a Confederate marine engineer during the American Civil War. He developed early hand-powered submarines, the most famous of which was posthumously named for him, H. L. Hunley.
CSS David was an American Civil War-era torpedo boat. On October 5, 1863, she undertook a partially successful attack on USS New Ironsides which was participating in the blockade of Charleston, South Carolina.
USS Wyalusing was a double-ended, side-wheel gunboat that served in the United States Navy during the American Civil War. She was named for the borough of Wyalusing in Bradford County, Pennsylvania.
The history of the submarine goes back to antiquity. Humanity has employed a variety of methods to travel underwater for exploration, recreation, research and significantly, warfare. While early attempts, such as those by Alexander the Great, were rudimentary, the advent of new propulsion systems, fuels, and sonar, propelled an increase in submarine technology. The introduction of the diesel engine, then the nuclear submarine, saw great expansion in submarine use — and specifically military use — during World War I, World War II, and the Cold War. The Second World War use of the U-Boat by the Kriegsmarine against the Royal Navy and commercial shipping, and the Cold War's use of submarines by the United States and Russia, helped solidify the submarine's place in popular culture. The latter conflicts also saw an increasing role for the military submarine as a tool of subterfuge, hidden warfare, and nuclear deterrent. The military use of submarines continues to this day, predominantly by North Korea, China, the United States and Russia.
A naval ram is a weapon fitted to varied types of ships, dating back to antiquity. The weapon comprised an underwater prolongation of the bow of the ship to form an armoured beak, usually between 2 and 4 meters (6–12 ft) in length. This would be driven into the hull of an enemy ship to puncture, sink or disable it.
USS Hoyt was a steamer acquired by the Union Navy during the American Civil War. She was used by the Union Navy for various tasks, including those of a torpedo boat.
USS Bazely was a steamer acquired by the Union Navy during the American Civil War. She was used by the Union Navy in a tugboat/patrol boat role in support of the Union Navy blockade of Confederate waterways.
USS Shamrock was a large seaworthy steamer with powerful guns, acquired by the Union Navy during the American Civil War. She was used by the Union Navy as a gunboat in support of the Union Navy blockade of Confederate waterways.
USS Alpha was a screw-propelled tugboat purchased by the Union Navy during the American Civil War. It was later fitted with a spar torpedo and operated 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.
The attack on USS New Ironsides in October 1863 was one of the first successful torpedo boat engagements in history. Confederate forces in Charleston, South Carolina deployed the newly built semi-submersible CSS David to attach a spar torpedo to the hull of USS New Ironsides. Though the attack is regarded as a rebel victory, the Union ship was saved from serious damage.
Daniel Griffin George alias William Smith was a Union Navy sailor in the American Civil War who received the U.S. military's highest decoration, the Medal of Honor.
CSS Squib, also known as CSS Infanta, was a Squib-class torpedo boat that served in the Confederate States Navy during the American Civil War. Squib was laid down in 1863, and was launched in early 1864. Her design was a form of launch armed with a spar torpedo. Initially serving on the James River as a flag of truce boat, she snuck into the Union Navy anchorage at Hampton Roads and attacked the steam frigate USS Minnesota early on the morning of April 9, 1864. Minnesota was damaged but not sunk, and Squib was able to escape back upriver. At an unknown time in mid-1864, Squib was moved by rail to the Wilmington, North Carolina, area, where she served on the Cape Fear River. Records of her service at Wilmington after November 1864 are not extant, but she may have resupplied a Confederate fortification during the Second Battle of Fort Fisher in January 1865. The next month, the Confederates withdrew from Wilmington, and Squib was scuttled off Cape Fear.
The Squib class torpedo boats were built for the Confederate States Navy during the later stages of the American Civil War. After the torpedo boat CSS David attacked and damaged the ironclad USS New Ironsides, the Confederates continued building torpedo boats with hopes of breaking the Union blockade. Four vessels of the class – CSS Hornet, CSS Wasp, CSS Squib, and CSS Scorpion – were constructed in Richmond, Virginia, in 1864. All were armed with a single spar torpedo and were powered by steam engines. Squib damaged the gunboat USS Minnesota in an attack on April 9, 1864, and was later sent to Wilmington, North Carolina, where she was scuttled in February 1865. The other three vessels of the class were all part of the James River Squadron and participated in the Battle of Trent's Reach on the night of January 23 and 24, 1865. Scorpion ran aground during the battle, and was forced downriver and out of control after the tender CSS Drewry exploded on January 24. She was later captured by Union forces and may have been burned. Hornet was sunk in a collision with another vessel on January 27, and Wasp was scuttled on the night of April 2/3, as the Confederates were abandoning Richmond.
