The marquis of Pianessa, that he might have the better opportunity of deluding and surprising the protestants of Roras, sent them word in answer, "That he was perfectly satisfied with their behaviour, for they had done right, and even rendered a service to their country, as the men who had attempted to pass the defile were not his troops, or sent by him, but a band of desperate robbers, who had, for some time, infested those parts, and been a terror to the neighbouring country." To give a greater colour to his treachery, he then published an ambiguous proclamation seemingly favourable to the inhabitants.
Yet, the very day after this plausible proclamation, and specious conduct, the marquis sent 500 men to possess themselves of Roras, while the people, as he thought, were lulled into perfect security by his specious behaviour.
Captain Gianavel, however, was not to be deceived so easily: he, therefore, laid an ambuscade for this body of troops, as he had for the former, and compelled him to retire with very considerable loss.
Though foiled in these, two attempts, the marquis Pianessa determined on a third, which should be still more formidable; but first he imprudently published another proclamation, disowning any knowledge of the second attempt.
Soon after, 700 chosen men were sent upon the expedition, who, in spite of the fire from the protestants, forced the defile, entered Roras, and began to murder every person they met with, without distinction of age or sex. The protestant captain Gianavel, at the head of a small body, though he had lost the defile, determined to dispute their passage through a fortified pass that led to the richest and best part of the town. Here he was successful, by keeping up a continual fire, and by means of his men being all complete marksmen. The Roman catholic commander was greatly staggered at this opposition, as he imagined that he had surmounted all difficulties. He, however, did his endeavours to force the pass, but being able to bring up only twelve men in front at a time, and the protestants being secured by a breastwork, he found he should be baffled by the handful of men who opposed him.
Enraged at the loss of so many of his troops, and fearful of disgrace if he persisted in attempting what appeared so impracticable, he thought it the wisest thing to retreat. Unwilling, however, to withdraw his men by the defile at which he had entered, on account of the difficulty and danger of the enterprise, he determined to retreat towards Villaro, by another pass called Piampra, which, though hard of access, was easy of descent. But in this he met with a disappointment, for captain Gianavel having posted his little band here, greatly annoyed the troops as they passed, and even pursued their rear till they entered the open country.
