Action Of 9 August 1780

The action of 9 August 1780 was a naval engagement of the American Revolutionary War, in which a Spanish fleet, led by Admiral Luis de Córdova y Córdova, along with a squadron of French ships, encountered a large British convoy. The Spanish and French force captured almost all the merchant vessels in the convoy, which dealt a severe blow to the commerce of Great Britain.

The British convoy, escorted by (74 guns, under Captain Sir John Moutray) and two frigates - ''Thetis'' (36 guns) and ''Southampton'' (36 guns), sailed from Portsmouth on 27 July. On 9 August, they encountered the Spanish fleet.

The Franco-Spanish fleet captured 55 of the 63 merchant vessels present, making it one of the most complete naval captures ever made. The losses, were, in total 80,000 muskets, equipment for 40,000 troops, 294 cannons, and 3,144 men. The financial impact of the losses were estimated to be around £1,500,000 (£1,000,000 in gold and £500,000 – £600,000 in equipment and ships). The action also helped to derail a secret British diplomatic effort to make peace with Spain.Syrett pp.136–137 The loss was still remembered in Great Britain (by then the United Kingdom) 30 years later, at the height of the Napoleonic Wars.Parkinson p.38

Background

The British convoy sailed from Portsmouth, and consisted of 63 merchant vessels. The convoy included East Indiamen, West Indiamen, 18 victuallers, military storeships, and transports carrying the 90th Regiment of Foot. The troops were intended for service in the West Indies, and they had tents and camp equipment with them. Besides arms, ammunition, and a train of artillery, the five East India vessels carried a large quantity of naval-stores to supply the British squadron in that area.

On the morning of 2 August, the convoy fell in with the Channel Fleet. The Channel Fleet accompanied the convoy for several hours, to a point 112 leagues off the Isles of Scilly, where the two groups of ships parted company.

Interception

Following the instructions given to Luis de Córdova by Don Jose Moñino, count of Floridablanca, the Spanish fleet set sail from Cádiz and sailed as far as Madeira and the Canary Islands, where Don Luís deployed several frigates to spot the convoy. One of these frigates intercepted the convoy on the night of 8 August.''Listado de presas británicas capturadas por la escuadra de Luis de Córdoba en 1780''

The news was greeted with caution, because there was doubt as to whether the ships were the Channel Fleet or the British convoy. The deputy Spanish commander, José de Mazarredo, called for an immediate attack. He concluded that there was no reason for the British fleet to be sailing so far from the Channel, and argued that all the suspected ships had to be a convoy under escort.

When strange sails (those of the Spanish fleet) were spotted, Captain Moutray signalled his ships to alter course and follow him close to the wind. The two frigates (''Thetis'' and ''Southampton'') and eight of the convoy followed the ''Ramillies'' and so escaped, but the rest of the British convoy mistook the lanterns at mast head of the ''Santísima Trinidad'' for those of their own commander, and fooled by a ruse of war, they steered accordingly.Botta p.449 At daybreak, they found themselves intermingled with the Spanish fleet.Botta p.449 Admiral de Cordova enveloped them, and hoisted signals to launch a general chase.Botta p.449

de Córdova's fleet captured 50 West Indiamen, including those chartered by the crown, and the five East Indiamen, ''Gatton'', ''Godfrey'', ''Hillsborough'', ''Mountstuart'' and ''Royal George'', totaling to 55 captured ships. The British loss was the worst disaster in the history of the East India Company. The 120-gun ship of the line ''Santísima Trinidad'', the flagship of Admiral de Córdova, fired on ''Mountstuart'' and ''Godfrey'' to induce them to strike. ''Gatton'' was also attacked by the '' Purísima Concepción'' and set on fire, but the fire was later brought under control, and the ship was seized. A frigate flotilla, commanded by Santiago de Liniers, and part of the ''Concepción'' squadron, captured the 30-gun East Indiaman ''Hillsborough''.

The captured British ships were brought to Cádiz, which was an unusual spectacle since the capture of such a great enemy convoy by any navy was an uncommon event; de Córdova's fleet did this on two occasions. All the ships, including the five East Indiamen, were incorporated into the Spanish merchant fleet. This was a major intelligence failure, for the British Admiralty did not learn of the presence of an enemy fleet at sea until 4 August, and neither did Geary nor Captain John Moutray.

Aftermath

The Spaniards behaved with great humanity to their prisoners, repaying the generous treatment which their countrymen had been given by Admiral Rodney.The Scots Magazine. October 1780, p.547

This Spanish victory, compounded by the serious storm losses in the Caribbean, produced a financial crisis among marine insurance underwriters throughout Europe. Many went bankrupt, and war insurance rates, already remarkably high due to the presence of privateers, were driven to intolerable levels. It also increased and made increasingly public the dissatisfaction which prevailed against the ministry, and against the conduct and government of the Royal Navy.

This successful interception shows that the English fleet, dispersed in too many theaters of operations, lost control of the Atlantic routes in 1780.

The five British East Indiaman were brought into Spanish service. The Spanish navy commissioned the 30-gun ''Hillsborough'' as the 12-gun store-ship ''Santa Clotilde'', the 28-gun ''Mountstuart'' as the 34-gun ''Santa Balvina'', the 28-gun ''Royal George'' as the 40-gun ''Real Jorge'', the 28-gun ''Godfrey'' as the 34-gun ''Santa Biviana'' and the 28-gun ''Gatton'' as the 34-gun ''Santa Paula''.Vela, pp. 120-122.

Among the British merchantmen who managed to escape were ''British Queen'' and ''Fanny'', whose copper sheathing helped distance their pursuers.Cunat, p.42
