In 1574, Vidal Guyard, a hatmaker of Le Puy, placed himself at the head of a hundred and twenty Calvinists, and, favoured by the moon, on the night of January 9th approached Espaly, and by penetrating into the castle by a drain succeeded in surprising the garrison and making themselves masters of the place. The news reached Le Puy through fugitives from the town, and next day the young men of the city, acting against the advice of the Bishop, determined on retaking the fortress. A crowd of citizens armed, assumed a white cross on their breasts, and marched against the place. But heavy rain came on, they were drenched to the skin, and their powder and courage were damped, so they returned having effected nothing. The Calvinists now set to work to destroy the houses in the little town, sparing only such as were redeemed by their owners with a heavy money payment.
On January 20th the Baron de S. Vidal, whom the Bishop had summoned to his aid, assembled troops at Le Puy and marched to Espaly, forced his way into the town, but could effect nothing against the castle, that was accessible by one path only, cut in the face of the rock. One of the garrison with his arquebus wounded S. Vidal in the shoulder. After that they made a sortie and did much execution among the besiegers.
S. Vidal, despairing of reducing the place by force of arms, resolved on trying negotiation. But Guyard demanded such an exorbitant sum for its surrender that it was refused. S. Vidal now tried stratagem. He framed a letter, as from Guyard, addressed to the consuls of Le Puy, offering to deliver up the castle, his lieutenant Morfouse, and the garrison, if his own life were spared and he were liberally rewarded. This letter was smuggled into the fortress, read by Morfouse, and in a paroxysm of jealousy and alarm he and the rest fell on Guyard and killed him. Then they entered into communication with S. Vidal, and surrendered on February 3rd, the day on which the baron received the news of his nomination by the King to be governor of Le Velay. Le Puy itself had undergone a siege by the Huguenots twelve years before this.
In 1562 the terrible Baron des Adrets, who was in Dauphiné stamping out every spark of Catholicism, deputed his lieutenant, Blacons, to secure Le Puy. Blacons was a man as ruthless as his commander, but without his military genius. It was settled that Blacons should assemble an army at Pont-en-Peyrat, a village on the borders of Forez and Velay. Thither accordingly gathered the Calvinists and a horde of adventurers thirsting for the pillage of the wealthy city and the shrine of the Madonna. The consuls of Le Puy sent the brother of their seneschal, Christopher d'Allègre, with 20,000 livres to treat with Blacons, and offer this sum if he would divert his column on some other town. Christopher d'Allègre, who was himself a Calvinist, and had been selected for the embassy on that ground, pocketed the money without intimating to Blacons the purpose for which it had been confided to him, and was instant in urging the Huguenot captain to capture and sack the city. The consuls, bishop, and chapter met in consultation and armed all the male inhabitants of the place, and hastily repaired the fortifications.
On August 4th arrived the citizens of S. Paulien, escaping with their goods and chatels from the Calvinists with terrible stories of outrage and murder committed by them. The alarm-bells pealed; a message was sent to the Viscount Polignac for aid, but he remained inert on the top of his rock, alleging that he had not a force sufficient at his disposal to be able materially to assist the citizens.
On the night of the same day the siege began. The Huguenots crossed the Borne, which was then dry, and planted their cannon. After a steady bombardment they rushed to the assault, and a desperate struggle ensued. Towards evening of August 5th the resistance of the citizens slackened, and the Calvinists pressed on, when a postern was thrown open and out poured a body of monks and friars variously armed. They fell upon the enemy in flank and put them to rout. The members of the monasteries and convents round Le Puy had fled to the city at the approach of Blacons, and had been clustered on the top of the rock Corneille watching events. Observing the progress of the Huguenots, and knowing that if the city fell every one of them would be hung or hurled down the rock, they had gone to the episcopal armoury and seized whatever weapons came to hand; and these men determined the fate of the engagement.
The disconcerted Huguenots retired for the night to Espaly. Next day they returned to the assault, and planted their cannon on a height whence they could play on the town. The suburb of Aiguilhe fell into their hands and was sacked. The hospital and the monasteries were burnt, the church of S. Laurence and the chapel of S. Michael were plundered and the carved work mutilated. If the latter escaped better than the former, it was due to the height at which it stood, and the danger attending any who climbed aloft to smash the sculptures with axes and hammers.
On the third day the Calvinists met with no better success. One man troubled them greatly, an aged hermit from the Mont Denise, who had been an artillery officer in his younger days. He was now very old and bent double; but the fire of battle kindled in his veins, and he undertook the disposition of the artillery and pointed the guns. "That holy man," says a contemporary historian, "did so well that he killed more men than did all the arquebusiers together."
The Huguenots lost heart and demanded a parley. They sent Christopher d'Allègre as their envoy into the city. This man must have been endowed with considerable effrontery to accept such an office, after having betrayed and robbed his fellow-citizens. He appeared before the consuls with a confident air, and demanded that the gates should be thrown open to Blacons. "How can you suppose," said he, "that we intend harm, we who are zealous propagators of the Reformed religion and the defenders of the oppressed? We are incapable of committing acts of violence. We will not exact of you any contribution, not even food for our men. All that we seek is to hew in pieces the gods of wood and stone and emblems that profane the temple of the living God."
