Twelve Dutch ships besieged Puerto de Cavite, the home of the Manila galleons, on 10 June. The Spaniards and Filipinos defended the port with artillery fire and sank the Dutch flagship. Subsequently, the Dutch left with the Spaniards and Filipinos still maintaining control over the port. This came at a great cost since Porta Vaga, a Spanish stone fort that defended the area, was destroyed. The Dutch then went on to harass the Manila Bay area until the war's end in 1648 with the Treaty of Münster.
