The Battle of Bayona Islands, also known as the Battle of Bayona Bay, was a naval engagement that took place in early of 1590, off Bayona Islands (present-day Cíes Islands), near Bayona (or Baiona) and Vigo, Spain, between a small Spanish naval force commanded by Captain Don Pedro de Zubiaur, and an Anglo-Dutch flotilla of 14 ships, during the Eighty Years' War, and in the context of the Anglo-Spanish War (1585–1604) and the French Wars of Religion. After several hours of hard combat, the Spanish naval force composed by three flyboats, achieved a great success, and the Anglo-Dutch fleet was totally defeated. The flagship of the Dutch was boarded and captured, including another six ships more. Finally, the rest of the Dutch fleet was forced to surrender.
