In the gulf of La Silanga we met with a very severe and dangerous tempest, of which we rid ourselves by exorcisms and sacred relics, as is our way in dealing with things evidently planned by the evil one. Here Nicolas Gonçalez waited with eight caracoas to tow the champans through La Silanga, which is a strait of the sea two leguas long, between the great island of Mindanao and another and small island. His Lordship, with four of the caracoas, went to Punta de Flechas, so called from the ceremony and superstition of the Moros in shooting arrows at one of its rocks when they are returning to their own country, to show their thankfulness to Mahomet. Here we remained for two days, awaiting the vessels of the fleet; during this time I said mass on shore, having beforehand uttered tremendous conjurations against the evil one, as holy Mother Church is wont to do, with her exorcisms, holy water, etc. Then our people burned all the arrows, of infinite number, that were fixed on that headland, with a thousand other things--articles of food, such as fish, eggs, etc.--which, as a sign of their devotion, they are wont to leave fastened to the rock with black pegs. We set up a number of crosses in different places, and then the name of the place was solemnly changed to Punta de San Sebastian, in order that that saint, with his holy arrows, might complete the destruction of those infernal and accursed ones which for so many years have vexed us. The name was given also in commemoration of the fact that Don Sebastian [_i.e._, Corcuera] has been the first governor to cast anchor here and to round this cape; besides this, the marvelous fall of this rock in the night when Nicolas Gonçalez fought within sight of it, we all attribute to this saint, who desired to give to Don Sebastian pledges for the glorious campaign of Mindanao, since only that part of the rock fell which faced toward Mindanao--as we all saw with wonder. While we were here, a light vessel came from the enemy to reconnoiter our fleet; our falua gave chase, but, being very far away, could not overtake it. We, however, encountered a small boat containing four of our Indian captives who had fled from the enemy; they informed us that several Javanese ships were on the point of departure from Mindanao, laden with Christian slaves. I confess to your Reverence that this was not news to his Lordship, but he was cut to the heart by the misery of so many souls, and he at once decided to sail night and day in order to overtake the ships. This holy zeal was the sole and true reason for his pushing on without halt till he came up with them, instead of waiting for his fleet; and he was well rewarded by Heaven with so fortunate a victory, as your Reverence will see.
