The Battle of Cape St. Vincent (Spanish: Batalla del Cabo de San Vicente) was a fleet action fought off Cape St. Vincent on 16–17 January 1780 during the American Revolutionary War. A Royal Navy fleet under Admiral of the White Sir George Rodney defeated a smaller Spanish Navy fleet under Squadron Commander Juan de Lángara in what became known as the Moonlight Battle (batalla a la luz de la luna), unusual since the Age of Sail saw almost exclusively daytime battles. It was the first major British naval victory of the war, and proved the maneuvering value of copper sheathed hulls. On 21 June 1779 Spain had joined its ally France, which was allied with the United States, in their war with Britain. Rodney was escorting a supply convoy with a powerful fleet of 18 ships of the line to relieve the Spanish siege of Gibraltar, when he encountered Lángara's fleet south of Cape St. Vincent on 16 January 1780. When Lángara saw the size of the British fleet, he rushed toward the safety of Cádiz, but the copper-sheathed British ships chased him down. In a running battle that lasted from mid-afternoon until after midnight, the British captured four ships of the line, including Lángara's flagship Fénix. Two other Spanish ships of the line were also captured but then retaken by their crews. Although Rodney's after action report claimed both ships were grounded and wrecked, one safely returned to Cádiz and resumed service. Following the battle, Rodney successfully resupplied Gibraltar and Minorca before continuing on to the British West Indies. Lángara was released on parole; his career did not suffer from the defeat, and he was promoted to lieutenant general by Charles III of Spain.
Background
One of Spain's principal goals upon its entry into the American War of Independence in 1779 was the recovery of Gibraltar, which had been lost to Great Britain in 1704. The Spanish planned to retake Gibraltar by blockading and starving out its garrison of British and Hanoverian troops. The siege formally began in June 1779 with a land blockade around the Rock of Gibraltar. The matching naval blockade was comparatively weak, however, and the British discovered that ships which were and small fast enough could evade the blockaders. By late 1779, however, supplies in Gibraltar had become seriously depleted, and its commander, General George Eliott, appealed to London for relief. In late December 1779 a large supply convoy and protecting fleet sailed from England under the command of Admiral of the White Sir George Rodney. Rodney's ultimate mission was to join the West Indies fleet, but he had secret instructions to first resupply Gibraltar and Minorca. On 4 January 1780 the fleet divided, with ships headed for the West Indies sailing westward. This left Rodney in command of 19 ships of the line, which were to accompany the supply ships to Gibraltar.
On 8 January 1780 ships from Rodney's fleet spotted a group of sails. Giving chase with their faster copper-clad ships, the British determined these to be a Spanish supply convoy protected by a single ship of the line and several frigates. The entire convoy was captured, with the lone ship of the line Guipuzcoana striking her colours after a perfunctory exchange of fire. Guipuzcoana was staffed with a small prize crew and renamed HMS Prince William, in honour of third son of the King, then serving as a midshipman with the fleet. Rodney detached HMS America and the frigate HMS Pearl to escort most of the captured ships back to England; Prince William was added to his fleet, as well as some of the Spanish supply ships rerouted to the Gibraltar garrison. On 12 January HMS Dublin, which had lost part of her topmast on 3 January, suffered additional damage and raised a distress flag. Assisted by HMS Shrewsbury, she limped into the neutral port of Lisbon on 16 January. News of the British fleet had come to the Spanish command. Drawn from the blockading force, a fleet of 11 ships of the line under Squadron Commander Juan de Lángara was dispatched to intercept Rodney's convoy. The Atlantic fleet of Admiral Luis de Córdova y Córdova at Cádiz was also alerted to try to catch him, but after learning the strength of Rodney's fleet, Córdova withdrew to Cádiz. On 16 January the fleets of Lángara and Rodney spotted each other around 1:00 pm south of Cape St. Vincent, the southwestern point of Portugal and the Iberian Peninsula. The weather was hazy, with heavy swells and occasional squalls.
Battle
Rodney was ill, and spent the entire action in his bunk. His flag captain, Walter Young, urged Rodney to give orders to engage when the Spanish fleet was first spotted, but Rodney only gave orders to form a line abreast. Lángara started to establish a line of battle, but when he realised the size of Rodney's fleet, he gave orders to make all sail for Cádiz. Around 2:00 pm, when Rodney felt certain that the ships seen were not the vanguard of a larger Spanish fleet, he ordered a general chase at top speed, and engage the Spanish ships from the rear as they came upon them. They were also instructed to sail to the lee side to interfere with Spanish toward shore, a tactic that also prevented the Spanish ships from opening their lowest gun ports. Because their copper-sheathed hulls reduced barnacles and drag, the British ships were faster and steadily gained on the Spanish. The chase lasted for about two hours, and the battle finally began around 4:00 pm. Santo Domingo, trailing in the Spanish fleet, received broadsides from HMS Edgar, HMS Marlborough, and HMS Ajax before blowing up around 4:40, with the loss of all but one of her crew. Marlborough and Ajax then passed Princesa to engage other Spanish ships. Princesa was eventually engaged in an hour-long battle with HMS Bedford before striking her colours at about 5:30. By 6:00 pm it was getting dark, and there was a discussion aboard HMS Sandwich, Rodney's flagship, about whether to continue the pursuit. Although Captain Young is credited in some accounts with pushing Rodney to do so, the fleet physician Gilbert Blane reported it as a decision of the council. The chase continued into the dark, squally night, leading to it later being known as the "Moonlight Battle", since it was uncommon at the time for naval battles to continue after sunset. At 7:30 pm, HMS Defence came upon Lángara's flagship Fénix, engaging her for over an hour. HMS Montagu and HMS Prince George broadsided Fénix in passing, and Lángara was wounded. Fénix finally struck her colours to HMS Bienfaisant, which arrived late in the battle and shot away her mainmast. Fénix's takeover was complicated by an outbreak of smallpox aboard Bienfaisant. Captain John MacBride, rather than sending over a possibly infected prize crew, apprised Lángara of the situation and put him and his crew on parole. At 9:15 Montagu engaged Diligente, which struck colors after her maintopmast was shot away. Around 11:00 pm San Eugenio surrendered after having all of her masts shot away by HMS Cumberland, but the difficult seas made it impossible to board a prize crew until morning. The San Eugenio duel was passed by HMS Culloden and Prince George, which engaged San Julián and compelled her crew to strike colours around 1:00 am. The last ship to surrender was Monarca. She nearly escaped, shooting away HMS Alcide's topmast, but was engaged in a running battle with the much smaller frigate HMS Apollo, which managed to keep up the fight for an hour. Rodney's flagship Sandwich came upon the scene around 2:00 am and fired a broadside, unaware that Monarca had already hauled down her flag. The British took six ships. Four Spanish ships of the line and the two frigates escaped, although sources are unclear if two of these ships were even present at the time of the battle. Lángara's report states that San Justo and San Genaro were not in his line of battle, though they were listed as part of his fleet. By one account, Lángara had dispatched these two ship to investigate other unidentified sails sometime before the action. Rodney's report states that San Justo escaped but was damaged in battle, and that San Genaro escaped without damage.
Aftermath
With the arrival of daylight, it was clear that the British fleet and their prize ships were dangerously close to a lee shore with an onshore breeze. One of the prizes, San Julián, was recorded by Rodney as too badly damaged to save, and was driven ashore. Another prize, San Eugenio, was retaken by her crew and managed to reach Cádiz; she was later restored to service within two months, and remained so until taken to pieces at Cádiz in 1804. A Spanish history claims that the prize crews of both ships needed the captive Spanish crewmen to escape the lee shore. The Spanish captains retook control, imprisoned the British crews, and sailed to Cádiz. The British reported their casualties as 32 killed, 102 wounded. The supply convoy sailed into Gibraltar on 19 January, driving the remaining blockade fleet back to port in Algeciras. Rodney arrived several days later, after first stopping in Tangier. The wounded Spanish prisoners, who included Lángara, were offloaded there, and the British garrison was heartened by the arrival of the supplies and the presence of Prince William Henry. After also resupplying Minorca, Rodney sailed for the West Indies in February, detaching part of the fleet for service in the Channel. This homebound fleet intercepted a French fleet destined for the East Indies, capturing one warship and three supply ships. Gibraltar was resupplied twice more before the siege was lifted at the end of the war in 1783. Lángara and other captured Spanish officers were eventually released on parole, with Charles III of Spain promoting Lángara to lieutenant general. He continued to serve in the Spanish navy, being appointed as the naval minister during the French Revolutionary Wars. Rodney was lauded for his victory, the first major victory of the war by the Royal Navy over its European opponents. He distinguished himself for the remainder of the war, notably winning the 1782 Battle of the Saintes in which he captured French Admiral de Grasse. He was, however, criticised by Captain Young, who portrayed him as weak and indecisive in the battle with Lángara. (He was also rebuked by the admiralty for leaving a ship of the line at Gibraltar, against his express orders.) Rodney's observations on the benefits of copper sheathing in the victory were influential in British Admiralty decisions to deploy the technology more widely.
== Order of battle == None of the listed sources give an accurate accounting of the ships in Rodney's fleet at the time of the action. Robert Beatson lists the composition of the fleet at its departure from England, and notes which ships separated to go to the West Indies, as well as those detached to England to return the prizes captured on 8 January. He does not list two ships (Dublin and Shrewsbury, identified in despatches reprinted by Syrett) that were separated from the fleet on 13 January. Furthermore, HMS Prince William is sometimes misunderstood to have been part of the prize escort back to England, but she was present at Gibraltar after the action. Beatson also fails to list a number of frigates, including Apollo, which played a key role in the capture of Monarca.
There are some discrepancies between British and Spanish sources regarding Lángara's fleet, principally in its number of guns. The table below lists the Spanish records of Lángara's fleet. However, Beatson lists all of the Spanish ships of the line at 70 guns, except that he correctly rates Fénix at 80 guns, but San Julián incorrectly at 64 guns. Spanish archives confirm this except for San Julián. One frigate, Santa Rosalia, is listed by Beatson at 28 guns, although she was actually 26 guns. The identify of the second Spanish frigate is different in the two listings. Beatson records her as Santa Gertrudis, 26 guns, with captain Don Annibal Cassoni, while Duro's listing describes her as Santa Cecilia, 34, captain Don Domingo Pérez de Grandallana; Spanish archives confirm the latter. Both frigates did not participate in the battle, and returned to Cádiz.
