In 1441, a young officer named Antonio Gonzales made a voyage in a small vessel, with a crew of twenty-one men, to the island where so great a number of sea wolves had been seen in the former voyage of Alphonzo Gonzales Baldaya in 1435. In this voyage Alphonzo Gotterez, a gentleman of the bed-chamber to Don Henry, acted as secretary, and the two adventurers were instructed to endeavour to obtain an account of the country and its inhabitants, and to procure a cargo of the skins of the seals or sea wolves, that the voyage might not be entirely destitute of some commercial advantages. After accomplishing this part of his instructions, Gonzales determined to use his utmost efforts for procuring some of the inhabitants of the country to carry back with him to Sagres. For this purpose, he landed at the beginning of the night with nine associates, and having advanced about ten miles into the interior, discovered a native following a camel. The sudden appearance of the Portuguese rendered the astonished Moor perfectly motionless, and before he could recover from his surprize he was seized by Gotterez. On their return to the shore with their prisoner, they traced some recent footsteps on the sand, which led them in view of about forty natives, who withdrew to an adjoining hill, but the Portuguese secured a female Moor who had strayed from the party. With these two prisoners they returned to their vessel, not choosing to run any unnecessary risk, or to make any needless attack upon the natives, which was contrary to the express orders of Don Henry. When preparing next morning to set sail on their return to Portugal, another Portuguese ship arrived, which was commanded by Nuno Tristan, a gentleman of the princes household. Encouraged by this reinforcement, a second expedition into the interior was immediately resolved upon, in which Nuno Tristan, Diego de Vigliadores, and Gonzales de Cintra, joined with Alphonzo Gonzales and Alphonzo Gotterez. Advancing again under night, they soon perceived a party of the natives whom they immediately attacked, shouting out Portugal! Portugal! San Jago! San Jago! The Moors were at first stupified with fear and surprise; but recovering from their panic, a struggle ensued, in which three of the Moors were slain, and ten made prisoners, the Portuguese being indebted for their safety to their defensive armour. After endeavouring, in vain, to establish an intercourse with the Moors for the redemption of the prisoners, Alphonzo Gonzales returned to Sagres with a cargo of skins and the Moorish prisoners, and was honourably rewarded by his discerning master. The place of this exploit was named Puerto del Cavallero, or the Knights Harbour, on occasion of Gonzales being there knighted by Nuno Tristan.
