Neither has that island of Hermosa such a location that it can be desirable for the ships of Filipinas that sail both to Japon and to Macan, to put in or to seek shelter there; and even less so for those returning from a port where they have taken refuge when they sail to Nueva Espana, or when, in sailing from Nueva Espana to Filipinas, by arriving late, the vendavals overtake them; or for ships on any other of the courses that we sail today.
But if one would say that it is a matter of importance for greater attempts that could be offered in time, by reason of the entrance into or conversion of China, that is not approved now. On the contrary, I fear from the caution and mistrust of the Chinese, that if we maintain a settlement in the island of Hermosa, and it is not clear to them that it is strictly necessary for that conservation, [they will act] without heeding other ends which they must obtain by way of diverting the trade with the Filipinas (since we see that they forced the Portuguese to tear down the fortification that they permitted them to erect in Macan, in view of the risk of its being captured by the Dutch in the year 622, who threatened to return to attempt it with a greater fleet the following year, although they had not returned up to the year 625). They are not unaware that Castilians and Portuguese are vassals of one and the same king. Neither have the Dutch failed to publish (as they did in Japon), that it is the custom of the king of Espana to conquer kingdoms under pretext of religion. That report, according to the religious of Japon themselves, has been one of the chief causes for the instigation of so terrible a persecution against Christians. Very true is it that the success in conversion in which his Majesty has so disinterested and holy an end, can neither be assured nor guided only by human reason. Consequently, what I judge to be an unsuitable thing might be the best method to attain it. In this argument one ought also to consider the heathen natives themselves in the island of Hermosa; but, admitting this, even for them at present I conclude that his Majesty is under no obligations whatever, because he has in the Filipinas not a few Indians who pay tribute, but who do not have sufficient ministers to instruct them. Also there are many heathen, who, because their country is not yet conquered, are without any knowledge at all of the holy gospel. But I shall not go into greater detail on this point, for it may, perhaps, seem to be outside the question.
Neither do I imagine that all that has occurred to me concerning this matter, and much more, has been left unconsidered by Don Fernando de Silva, governor of Filipinas, at whose order a site was occupied on Hermosa Island; for he is a very prudent gentleman and a gallant soldier, and one who will not have permitted the desire for glory and honor, of which the discoverers and conquerors of new lands are justly worthy, to carry him away. Yet I do not, on that account, regard myself as under no obligations to advise you of my opinion. Madrid, December 20, 1627.
