Soon afterward, Captain Juan Saicedo, Legaspi's grandson, was sent to the island of Luzon to reconnoiter the territory and to bring it into subjection to Spain. Martin de Goiti and a few soldiers accompanied him. They were well received by the various chiefs they visited. Among these were King Lacandola, the Rajah of Tondo, and his nephew, the stern young Rajah Soliman, of Manila. Intimidated by the countenances of the warlike-looking foreigners, and awed by the mysterious symbols of their priests, these superstitious chiefs agreed forever, for no consideration, and without reservation, to yield up their independence, to pay tribute, and to aid in the subjugation of their own countrymen. A treaty of peace having been made, the Spaniards acted as if they were the natural owners of the soil. Young Soliman, however, soon found occasion to demonstrate that he, at least, had no intention of carrying out his part of this enforced contract. He sowed the seeds of insurrection broadcast among the various surrounding tribes, and not only carried on an offensive warfare against the invaders, but set fire to his capital, Manila, that it might not become the spoil of the invaders. Soliman and his little army were put to flight by Salcedo, who generously pardoned the young chief upon his again swearing fealty to the King of Spain. Then, while Goiti with his forces remained in the vicinity of Manila, Salcedo pursued his adventurous way as far as the Taal district. All the country of the Batangas province was also subdued by him. About this time Salcedo himself, severely wounded by an arrow, returned to Manila. Legaspi being informed of the occurrences in Luzon, soon joined Salcedo at Cavité, where chief Lacondola gave his submission. Legaspi, continuing his journey to Manila, was there received with much pomp and acclamation. He not only took formal possession of all the surrounding territory, but also declared Manila to be the capital of the whole Archipelago. He next publicly proclaimed the sovereignty of the King of Spain over all the islands. Speaking of this period, the old chronicler, Gaspar de San Agustin, says: "He (Legaspi) ordered them (the natives) to finish the building of the fort in construction at the mouth of the river (Pasig), so that His Majesty's artillery might be mounted therein for the defense of the port and the town. He also ordered them to build a large house inside the battlement walls for Legaspi's own residence, and another large house and church for the priests. "Besides building these two large houses, he told them to erect 150 dwellings of moderate size for the remainder of the Spaniards to live in. All this they promptly promised to do; but they did not obey; for the Spaniards were themselves obliged to complete the work of the fortifications."
