Salcedo ordered installed in the prow of the galley a stone-throwing mortar. He and his men then spent the night on shore, while 20 soldiers and numerous allies from Manila remained with Carvajal on the galley with orders that when they heard firing, they should proceed with the attack on the bulwarks and the houses in the town, while Salcedo and his men tried to enter through the wall by the arroyo. When they heard the sound of the bugle, the signal that they had taken the town, they were to stop firing.
