Señor Azevedo was not long in discovering that the flame of rebellion was only smothered, and not extinguished; and he gave information to Señor Anda to that effect, requesting him to send a force to keep the deluded in awe. Señor Anda despatched one hundred and eighty men from his camp to Pangasinan, and gave orders to Don Manuel Arza to extirpate the last remains of the rebellion from Ylocos, that he might form a junction with the troops going to Manila under command of Don Pedro Bonardel. As soon as the rebels knew that troops were going from Manila, they assembled tumultuously in the town of Calasiao, where the Alcalde was with two Spaniards and two Dominican friars in the convent. The Indians besieged them, but they defended themselves with their muskets; and the rebels not daring to make an assault on the convent, chose the alternative of setting it on fire. The unfortunate party besieged had no other resource but to take refuge on the tower of the church, with the little provisions they could find at hand, where they maintained themselves five days, until our troops learning their unfortunate situation made a forced march to their assistance, routing the rebels in their way. Bonardel pursued his march to Lingayen, the capital of the province, and putting every detachment of rebels to flight which came in his way, he fortified that town, and was joined by Don Manuel de Arza with a body of Indians which he brought from Ylocos, both by sea and land. Bonardel leaving the remainder of his people in Lingayen, took fifty men, and went to St. Fabian to liberate the Bishop and some Dominicans, whom the rebels detained as prisoners; he routed them, and although they had possessed themselves of the passes, he managed to join the rest of the army.
