The Battle of Cape St. Vincent was a naval engagement that took place on 16 June or 6 October 1606, during Eighty Years' War and Dutch–Portuguese War. A Spanish fleet under Admiral Luis Fajardo attacked the Dutch fleet led by Admiral Willem Haultain and Vice Admiral Regnier Klaazoon, which was blocking the Spanish-Portuguese coast to intercept the Spanish treasure fleet. The battle concluded in a Spanish victory; in which Klaazoon's flagship was destroyed, two ships were captured, and Haultain fled with the rest of the fleet to his country without having achieved his purpose.
