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.
