Ferrol Expedition

The Ferrol Expedition (or Battle of Brión) took place on 25 and 26 August 1800, and was an unsuccessful British attempt to capture Ferrol from Spain. Ferrol was a major Spanish naval base with a shipyard for shipbuilding and dry dock for repairs.
Background.
The primary object of the British expedition and fleet of 109 ships during the year 1800 was the conquest of Belle Île but the defences appeared too strong. The expedition therefore proceeded to the coast of Spain, where it arrived on 25 August.
Battle.
After a heavy cannonade against a small Spanish fort of eight 24-pounder cannon by the British ships of the line HMS "Impetueux" with 74 guns, HMS "London" with 96 guns, HMS "Courageux", HMS "Renown" and HMS "Captain", each with 74 guns.HMS Impetueus, HMS Brilliant , HMS Cynthia an the small gunner HMS St. Vincent, state on their logs to had took part on the gunnig of the small Fort. No mention on the HMS London and HMS Renow logs of being part of the gunning. 
Under the superintendence of Sir Edward Pellew, the British effected a landing at a small opening near Cape Prior. The army commander was Lieutenant-general Sir James Pulteney. The force landed consisted of seven British regiments, one of two battalions, and the rifle-corps totaling 8,000 troops and 16 field pieces.
The Spanish defenders of Ferrol were: Don Francisco Melgarejo (a Naval Engineer), commander of the naval department; Juan Moreno, commander of the squadron stationed in the harbour; Don Francisco Xavier Negrété, captain-general of the province; and Field Marshal Count Donadio, who commanded the fortifications that protected the coast. The Spanish ship of the line were: "Real Carlos" and "San Hermenegildo", each 112 guns; "San Fernando", 96 guns; "Argonauta", 80 guns; "San Antonio" and "San Agustín", each 74 guns.
The British rifle-corps advanced up a ridge and was attacked by a Spanish detachment which it drove back with some loss. Early on the morning of 26 August a considerable body of Spanish attacked the British on the heights of Brion and Balon but they were repulsed. British casualties were 16 killed and 68 wounded. The heights overlooked the town and harbour of Ferrol. That night, after observing the strength of the fortifications, the British troops and artillery were embarked back on their ships.
Aftermath.
The embarkation of the troops and artillery was effected, and soon after this failure on the coast of Galicia, another expedition, equally unsuccessful was directed on October against the city of Cadiz. The assault had to be abandoned due to an outbreak of yellow fever among British troops, 
After the unsuccessful attempt to capture Ferrol, the British Prime Minister William Pitt said in the House of Commons that: "If Great Britain had a naval station so easy to defend as Ferrol, due to its location, it would have been surrounded by a thick silver wall".
