The Battle of the Narrow Seas, also known as the Battle of the Goodwin Sands or Battle of the Dover Straits was a naval engagement that took place on 3–4 October 1602 during the Anglo-Spanish War of 1585 and part of the Dutch Revolt. An English fleet under Sir Robert Mansell intercepted and attacked six Spanish galleys under the command of Federico Spinola in the Dover Straits. The battle was fought initially off the coast of England and finally off the Spanish Netherlands. The English were soon joined by a Dutch fleet under Jan Adriaanszoon Cant, and they completed the destruction.
