The Battle of Vigo Bay, also known as the Battle of Rande (; ), was a naval engagement fought on 23 October 1702 during the opening years of the War of the Spanish Succession. The engagement followed an Anglo-Dutch attempt to capture the Spanish port of Cádiz in September in an effort to secure a naval base in the Iberian Peninsula. From this station the Allies had hoped to conduct operations in the western Mediterranean Sea, particularly against the French at Toulon. The amphibious assault, however, had proved a disaster, but as Admiral George Rooke retreated home in early October, he received news that the Spanish treasure fleet from America, laden with silver and merchandise, had entered Vigo Bay in northern Spain. Philips van Almonde convinced Rooke to attack the treasure ships, despite the lateness of the year and the fact that the vessels were protected by French ships-of-the-line. The engagement was an overwhelming naval success for the Allies: the entire French escort fleet, under the command of Château-Renault, together with the Spanish galleons and transports under Manuel de Velasco, had either been captured or destroyed. Yet because most of the treasure had been off-loaded before the attack, capturing the bulk of the silver cargo had eluded Rooke. Nevertheless, the victory was a welcome boost to Allied morale and had helped persuade the Portuguese King, Peter II, to abandon his earlier treaty with the French, and join the Grand Alliance. Background The accession of the Bourbon Philip V to the Spanish throne in 1700 had aroused little opposition in Spain. In the Spanish American empire, however, officials and colonists resisted French attempts to take over their trade. Dutch and English traders – though officially illegal – were accepted by the Spanish, but in the Caribbean, French admirals who had come to "protect" Spanish silver home to Europe were regarded with intense suspicion. The first French squadron sailed in April 1701 under the Marquis de Coëtlogon, but the Spanish governors would not even permit him to buy victuals, and he returned empty handed. Nevertheless, the weakness of the Spanish navy left the government in Madrid little choice but to rely on French warships for escort duty. Every effort was made to ensure that the bullion was landed in Spain rather than France, from where it might never return. The naval campaign of 1702 was therefore played out in two distant theatres
