In the year 1622 a decree appeared, by which the inhabitants of St. Jean were ordered to shut up the church, built there a few years before, and a payment of six thousand ducats required from the three valleys. At the same period Pope Gregory XV. granted to the Duke the tenth of all ecclesiastical revenues. In gratitude for this bounty, more vigorous measures were taken against the poor Vaudois. Those of Praviglielm were banished by the prefect of Saluces; and a great number in the valley of Barcelona, dependent on the Cardinal de Savoy, were driven thence in 1625, and fled into the south of France, or Piemontese valleys. Although the decree only mentioned the church of St. Jean, a regiment of infantry, in the val de Perouse, forced the inhabitants to demolish six of their churches, and then made a perfidious attack on St. Germain. The report of this treatment having spread into foreign countries, an ambassador extraordinary from Great Britain arrived at Turin, in 1627, to intercede for the Vaudois. He received a promise that they should not be any longer molested, and returned in October, having recommended them to the protection of some of the nobility. The following year, the French army having shown a disposition to attack the frontiers, the passes were placed under the defence of the Vaudois; who so well defended them, that no enemy penetrated into Piémont. A convent of capuchin monks was this year founded at Luzerne, by two of the noble family of Rorenco, lords of that place and La Tour, which has since taken a great part in our history. In 1629, another ambassador came from England, named Carlisle, who earnestly interceded for the Vaudois, and obtained the most honourable testimonies in their favour. But though the court was well disposed towards them, the implacable clergy always found means to evade its benevolent purposes. One of their contrivances was, to disperse a great number of monks through the valleys; but these, upon reference to the court, were at this time withdrawn. The Vaudois were also this year again called upon to defend the frontiers against a threatened attack, on the part of the French; but a truce having been concluded, it was not till 1630 that the enemy actually advanced by Susa and reduced Pignerol. The inhabitants of the valleys, after some hesitation, consented to submit, on being summoned to do so by Marshal Schomberg; but on condition that no one should be forced to bear arms against the Duke. A violent plague, this year, made great ravages, and most of the pastors fell victims to it. Charles Emanuel also died about the same time, and Victor Amadeus I. having succeeded him, peace was signed between Piémont, Spain, and France, by the articles of which the town of Pignerol and the val St. Martin were retained by the latter.
