End of Dutch threat in the Philippines

Although it was not known whether the Dutch would attack in 1647, given their defeats the previous year, nevertheless Governor Fajardo ordered that all possible defensive preparations be made, fortifying the city and ordering new warships to be built.

On June 6, 1647, Dutch vessels were sighted near Mariveles Island. In spite of the preparations, the Spanish had only one galleon (the San Diego) and two galleys ready to engage the enemy. The Dutch had twelve major vessels.

On June 12 the armada attacked the Spanish port of Cavite. The battle lasted eight hours, and the Spanish believed they had done much damage to the enemy flagship and the other vessels. The Spanish ships were not badly damaged and casualties were low. However, nearly every roof in the Spanish settlement was damaged by cannon fire, which particularly concentrated on the cathedral. On the nineteenth, the armada was split, with six ships sailing for the shipyard of Mindoro and the other six remaining in Manila Bay.

The Dutch next attacked Pampanga, where they captured the fortified monastery, taking prisoners and executing almost 200 Filipino defenders. The governor ordered solemn funeral rites for the dead and payments to their widows and orphans.

This year was the last in which the Dutch attacked the Manila area. There was an expedition the following year that arrived in Jolo in July. The Dutch had formed an alliance with an anti-Spanish king, Salicala. The Spanish garrison on the island was small, but survived a Dutch bombardment. The Dutch finally withdrew, and the Spanish made peace with the Joloans, and then also withdrew.

There was also an unsuccessful attack on Zamboanga in 1648. That year the Dutch promised the natives of Mindanao that they would return in 1649 with aid in support of a revolt against the Spanish. Several revolts did break out, the most serious being in the village of Lindáo. There most of the Spaniards were killed, and the survivors were forced to flee in a small river boat to Butuán. However, Dutch aid did not materialize.

The authorities from Manila issued a general pardon, and many of the Filipinos in the mountains surrendered. However, some of those were hanged and most of the rest were enslaved.

On October 2, 1649 the galleon Encarnación was wrecked at Sorsogon, en route from Acapulco.
