While the Royalists were carrying destruction through the villages of the Upper Cevennes, Cavalier, Salomon, and Abraham, in order to divert them from their purpose, resolved upon another descent into the low country, now comparatively ungarrisoned. With this object they gathered together some fifteen hundred men, and descended from the mountains by Collet, intending to cross the Gardon at Beaurivage. On Sunday, the 29th of April, they halted in the wood of Malaboissière, a little north of Mialet, for a day's preaching and worship; and after holding three services, which were largely attended, they directed their steps to the Tower of Belliot, a deserted farmhouse on the south of the present high road between Alais and Anduze.
The house had been built on the ruins of a feudal castle, and took its name from one of the old towers still standing. It was surrounded by a dry stone wall, forming a court, the entrance to which was closed by hurdles. On their arrival at this place late at night, the Camisards partook of the supper which had been prepared for them by their purveyor on the occasion—a miller of the neighbourhood, named Guignon—whose fidelity was assured not only by his apparent piety, but by the circumstance that two of his sons belonged to Cavalier's band.
No sooner, however, had the Camisards lain down to sleep than the miller, possessed by the demon of gold, set out directly for Alais, about three miles distant, and, reaching the quarters of Montrevel, sold the secret of Cavalier's sleeping-place to the marshal for fifty pieces of gold, and together with it the lives of his own sons and their fifteen hundred companions.
The marshal forthwith mustered all the available troops in Alais, consisting of eight regiments of foot (of which one was Irish) and two of dragoons, and set out at once for the Tower of Belliot, taking the precaution to set a strict guard upon all the gates, to prevent the possibility of any messenger leaving the place to warn Cavalier of his approach. The Royalists crept towards the tower in three bodies, so as to cut off their retreat in every direction. Meanwhile, the Camisards, unapprehensive of danger, lay wrapped in slumber, filling the tower, the barns, the stables, and outhouses.
The night was dark, and favoured the Royalists' approach. Suddenly, one of their divisions came upon the advanced Camisard sentinels. They fired, but were at once cut down. Those behind fled back to the sleeping camp, and raised the cry of alarm. Cavalier started up, calling his men "to arms," and, followed by about four hundred, he precipitated himself on the heads of the advancing columns. Driven back, they rallied again, more troops coming up to their support, and again they advanced to the attack.
To his dismay, Cavalier found the enemy in overwhelming force, enveloping his whole position. By great efforts he held them back until some four or five hundred more of his men had joined him, and then he gave way and retired behind a ravine or hollow, probably forming part of the fosse of the ancient château. Having there rallied his followers, he recrossed the ravine to make another desperate effort to relieve the remainder of his troop shut up in the tower.
A desperate encounter followed, in the midst of which two of the royalist columns, mistaking each other for enemies in the darkness, fired into each other and increased the confusion and the carnage. The moon rose on this dreadful scene, and revealed to the Royalists the smallness of the force opposed to them. The struggle was renewed again and again; Cavalier still seeking to relieve those shut up in the tower, and the Royalists, now concentrated and in force, to surround and destroy him.
At length, after the struggle had lasted for about five hours, Cavalier, in order to save the rest of his men, resolved on retiring before daybreak; and he succeeded in effecting his retreat without being pursued by the enemy.
The three hundred Camisards who continued shut up in the tower refused to surrender. They transformed the ruin into a fortress, barricading every entrance, and firing from every loophole. When their ammunition was expended, they hurled stones, joists, and tiles down upon their assailants from the summit of the tower. For four more hours they continued to hold out. Cannon were sent for from Alais, to blow in the doors; but before they arrived all was over. The place had been set on fire by hand grenades, and the imprisoned Camisards, singing psalms amidst the flames to their last breath, perished to a man.
This victory cost Montrevel dear. He lost some twelve hundred dead and wounded before the fatal Tower of Belliot; whilst Cavalier's loss was not less than four hundred dead, of whom a hundred and eighteen were found at daybreak along the brink of the ravine. One of these was mistaken for the body of Cavalier; on which Montrevel, with characteristic barbarity, ordered the head to be cut off and sent to Cavalier's mother for identification!
