From the close of the sixteenth century up to the year of the “Family Compact” wars (1763), Holland and Spain were relentless foes. To recount the numerous combats between their respective fleets during this period would itself require a volume. It will suffice here to show the bearing of these political conflicts upon the concerns of the Philippine colony. The Treaty of Antwerp, which was wrung from the Spaniards in 1609, twenty-eight years after the union of Spain and Portugal, broke the scourge of their tyranny, while it failed to assuage the mutual antipathy. One of the consequences of the “Wars of the Flanders,” which terminated with this treaty, was that the Dutch were obliged to seek in the Far East the merchandise which had hitherto been supplied to them from the Peninsula. The short-sighted policy of the Spaniards in closing to the Dutch the Portuguese markets, which were now theirs, brought upon themselves the destruction of the monopolies which they had gained by the union. The Dutch were now free, and their old tyrant’s policy induced them to independently establish their own trading headquarters in the Molucca Islands, whence they could obtain directly the produce forbidden to them in the home ports. Hence, from those islands, the ships of a powerful Netherlands Trading Company sallied forth from time to time to meet the Spanish galleons from Mexico with silver and manufactured goods. Previous to this, and during the Wars of the Flanders, Dutch corsairs hovered about the waters of the Moluccas, to take reprisals from the Spaniards. These encounters frequently took place at the eastern entrance of the San Bernadino Straits, where the Dutch were accustomed to hove-to in anticipation of the arrival of their prizes. In this manner, constantly roving about the Philippine waters, they enriched themselves at the expense of their detested adversary, and, in a small degree, avenged themselves of the bloodshed and oppression which for over sixty years had desolated the Low Countries. 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 Moluccas to attack the enemy in his own waters.
