The Battle of Cape St Vincent of 1641 took place on 4 November 1641 when a Spanish fleet commanded by Don Juan Alonso de Idiáquez y Robles intercepted a Dutch fleet led by Artus Gijsels during the Eighty Years' War. After a fierce battle two Dutch ships were lost but the Dutch claimed only a hundred of their men were killed; the Spanish fleet also lost two ships but over a thousand dead. The damaged Dutch fleet was forced to abandon its planned attack on the Spanish treasure fleet. (wiki)
