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.
The marquis of Pianessa, finding that all his attempts were frustrated, and that every artifice he used was only an alarm-signal to the inhabitants of Roras, determined to act openly, and therefore proclaimed, that ample rewards should be given to any one who would bear arms against the obstinate heretics of Roras, as he called them; and that any officer who would exterminate them should be rewarded in a princely manner.
This engaged captain Mario, a bigoted Roman catholic, and a desperate ruffian, to undertake the enterprise. He, therefore, obtained leave to raise a regiment in the following six towns: Lucerne, Borges, Famolas, Bobbio, Begnal, and Cavos.
Having completed his regiment, which consisted of 1000 men, he laid his plan not to go by the defiles or the passes, but to attempt gaining the summit of a rock, from whence he imagined he could pour his troops into the town without much difficulty or opposition.
The protestants suffered the Roman catholic troops to gain almost the summit of the rock, without giving them any opposition, or ever appearing in their sight: but when they had almost reached the top they made a most furious attack upon them; one party keeping up a well-directed and constant fire, and another party rolling down huge stones.
This stopped the career of the papist troops: many were killed by the musketry, and more by the stones, which beat them down the precipices. Several fell sacrifices to their hurry, for by attempting a precipitate retreat, they fell down, and were dashed to pieces; and captain Mario himself narrowly escaped with his life, for he fell from a craggy place into a river which washed the foot of the rock. He was taken up senseless, but afterwards recovered, though he was ill of the bruises for a long time; and, at length, he fell into a decline at Lucerne, where he died.
Another body of troops was ordered from the camp at Villaro, to make an attempt upon Roras; but these were likewise defeated, by means of the protestants' ambush-fighting, and compelled to retreat again to the camp at Villaro.
After each of these signal victories, captain Gianavel made a suitable discourse to his men, causing them to kneel down, and return thanks to the Almighty for his providential protection; and usually concluded with the eleventh psalm, where the subject is placing confidence in God.
