In 1646, a series of five naval actions known as the Battles of La Naval de Manila was fought between the forces of Spain and the Dutch Republic, as part of the Eighty Years' War. Although the Spanish forces consisted of just two Manila galleons and a galley with crews composed mainly of Filipino volunteers, against three separate Dutch squadrons, totaling eighteen ships, the Dutch squadrons were severely defeated in all fronts by the Spanish-Filipino forces, forcing the Dutch to abandon their plans for an invasion of the Philippines.
