The Battle of Cape St. Vincent (14 February 1797) was one of the opening battles of the Anglo-Spanish War (1796–1808), as part of the French Revolutionary Wars, where a British fleet under Admiral Sir John Jervis defeated a greatly superior Spanish fleet under Admiral Don José de Córdoba y Ramos near Cape St. Vincent, Portugal.
Background
After the signing of the Treaty of San Ildefonso in 1796 allying Spanish and French forces against Great Britain, the Royal Navy blockaded Spain in 1797, impairing communications with its empire. The Spanish declaration of war on Britain and Portugal in October 1796 made the British position in the Mediterranean untenable. The combined Franco-Spanish fleet of 38 ships of the line heavily outnumbered the British Mediterranean Fleet of fifteen ships of the line, forcing the British to evacuate their positions in first Corsica and then Elba. Early in 1797, the Spanish fleet of 27 ships of the line lay at Cartagena on the Mediterranean Sea. The Spanish planned to join the French fleet at Brest and escort a large merchant convoy, carrying mainly mercury for gold and silver production, from Cádiz. The convoy entered Cádiz harbour along with warships Neptuno, Terrible and Bahama, prior to running into the British force.
Don José de Córdoba and the Spanish fleet left Cartagena on 1 February and might have reached Cádiz safely but for a fierce Levanter, the easterly wind, blowing between Gibraltar and Cádiz, which pushed the Spanish fleet further out into the Atlantic than intended. As the winds died down, the fleet began working its way back to Cádiz. In the meantime, the British Mediterranean Fleet, under Admiral Sir John Jervis, had sailed from the Tagus with ten ships of the line to try to intercept the Spanish fleet. On 6 February, Jervis was joined off Cape St. Vincent by a reinforcement of five ships of the line from the Channel Fleet under Rear-Admiral William Parker. On 11 February, the British frigate HMS Minerve, under the command of Commodore Horatio Nelson, passed through the Spanish fleet unseen thanks to heavy fog. Nelson reached the British fleet of fifteen ships off Spain on 13 February, and told the location of the Spanish fleet to Jervis, commanding the fleet from his flagship Victory. In the fog, Nelson had not been able to count the Spanish ships, but Jervis's squadron immediately sailed to intercept them as they continued toward Cádiz. Early on the 14th, Jervis learnt that the Spanish fleet was 35 miles to windward.
Battle
Though Admiral Jervis still had no idea of the size of the fleet he was up against, during the night came the sounds for which he had been waiting: Spanish signal guns in the fog. At 2:50 a.m. came the report that the Spanish fleet was some fifteen miles distant. By 5:30 a.m., Niger reported them closer still, as a cold and foggy February dawn rose on the British fleet, formed in two lines of battle. Jervis turned to his officers on the quarter-deck of Victory and said, "A victory to England is very essential at this moment." Jervis put Captain Thomas Troubridge in Culloden in the lead. At 6:30 a.m., Culloden signalled that she could see five enemy sail to the south east, and along with Blenheim and Prince George turned toward the Spanish ships. As they loomed up out of the fog, a signal lieutenant in Barfleur described them as "thumpers, looming like Beachy Head in a fog." On the quarter-deck of Victory, Jervis, Captain Robert Calder and Captain Benjamin Hallowell counted the enemy ships: the British were outnumbered nearly two-to-one.
It would be difficult to disengage, and the situation would only get worse were the Spanish fleet to join up with the French: Jervis decided to continue. Hearing this, the Canadian Captain Hallowell became so excited he thumped the Admiral on the back, "That's right Sir John, and, by God, we'll give them a damn good licking!" The Spanish were formed in two loose columns, one of about 18 ships to windward and the other, of about nine ships, somewhat closer to the British. At about 10:30 a.m., the Spanish ships in the weather column were seen to wear ship and turn to port. This gave the impression that they might form a line and pass along the weather column of the British fleet, exposing the smaller British column to the fire of the larger Spanish division. At 11:00 a.m., Jervis ordered: "Form in a line of battle ahead and astern of Victory as most convenient." When this was completed the British fleet had formed a single line of battle, sailing south to pass between the two Spanish columns. At 11:12 a.m., Jervis made his next signal: "Engage the enemy" and then at 11:30 a.m.: "Admiral intends to pass through enemy lines". The Battle of Cape St. Vincent had begun.
