The Philippine Colony lost immense sums in the seizure of its galleons from Mexico, upon which it almost entirely depended for subsistence. Being a dependency of New Spain, its whole intercourse with the civilized world, its supplies of troops and European manufactured articles, were contingent upon the safe arrival of the galleons. Also the dollars with which they annually purchased cargoes from the Chinese for the galleons came from Mexico. Consequently, the Dutch usually took the aggressive in these sea-battles, although they were not always victorious. When there were no ships to meet, they bombarded the ports where others were being built. The Spaniards, on their part, from time to time fitted out vessels to run down to the Molucca Islands to attack the enemy in his own waters.
During the Governorship of Gomez Perez Dasmariñas (1590-93), the native King of Siao Island--one of the Molucca group--came to Manila to offer homage and vassalage to the representative of the King of Spain and Portugal, in return for protection against the incursions of the Dutch and the raids of the Ternate natives. Dasmariñas received him and the Spanish priests who accompanied him with affability, and, being satisfied with his credentials, he prepared a large expedition to go to the Moluccas to set matters in order. The fleet was composed of several frigates, 1 ship, 6 galleys, and 100 small vessels, all well armed. The fighting men numbered 100 Spaniards, 400 Pampanga and Tagálog arquebusiers, 1,000 Visaya archers and lancers, besides 100 Chinese to row the galleys. This expedition, which was calculated to be amply sufficient to subdue all the Moluccas, sailed from Cavite on October 6, 1593. The sailing ships having got far ahead of the galleys, they hove-to off Punta de Azúfre (N. of Maricaban Is.) to wait for them. The galleys arrived; and the next day they were able to start again in company. Meanwhile, a conspiracy was formed by the Chinese galleymen to murder all the Spaniards. Assuming these Chinese to be volunteers, their action would appear to be extremely vile. If, however, as is most probable, they were pressed into this military service to foreigners, it seems quite natural, that being forced to bloodshed without alternative, they should first fight for their own liberty, seeing that they had come to the Islands to trade.
