He himself, exercising duplicity and cunning, did not leave the city, or the houses of the Spanish during this time, in order to arouse less suspicion of himself. From there he managed the affair through his confidants; and in order to assure himself better of the result, and to ascertain the number of men of his race, and to make a census and list of them, he cunningly had each of them ordered to bring him a needle, which he pretended to be necessary for a certain work that he had to do. These needles he placed, as he received them, in a little box; and when he took them out of it, he found that he had sufficient men for his purpose. They began to construct the fort or quarters immediately at a distance of slightly more than one-half legua from the village of Tondo, among some estuaries and swamps, and in a hidden location. [9] They stored there some rice and other provisions, and weapons of little importance. The Sangleys began to gather there, especially the masses--the common people and day-laborers; for those of the parian, and the mechanics, although urged to do the same, did not resolve to do it, and remained quiet, guarding their houses and property. The restlessness of the Sangleys daily continued to become more inflamed. This, and the advices given to the governor and the Spaniards, kept the latter more anxious and apprehensive, and made them talk more openly of the matter. The Sangleys, seeing that their intention was discovered, and that delay might be of so great harm to them, determined, although the insurrection was planned for St. Andrew's day, the last of November, to anticipate that day, and to lose no more time. On Friday, the third day of the month of October, the eve of St. Francis, they collected very hurriedly in the above-mentioned fort; consequently, by nightfall, there were two thousand men in it. Joan Bautista de Vera--a thief in the role of an honest man, since he was the leader and organizer of the treason--went immediately to the city and told the governor that the Sangleys had risen, and that they were collecting on the other side of the river. The governor, suspecting the mischief, had him immediately arrested and carefully guarded; and he was afterward executed. Then, without tap of drum, the governor ordered the companies, both of the camp and the city, to be notified, and all to hold their arms in readiness. Very shortly after nightfall, Don Luys Dasmarinas, who was living near the monastery and church of Minondoc, on the other side of the river, came hurriedly to the city to advise the governor that the Sangleys had revolted. He asked for twenty soldiers to go to the other side [of the river], where he would guard the said monastery. Cristoval de Axqueta, sargento-mayor of the camp, went with these men, together with Don Luys. As the silence of night deepened, the noise made by the Sangleys grew louder, for they were continuing to assemble and were sounding horns and other instruments, after their fashion.
