There were between two and three millions of Protestants in France.[11] The dragoons were sent in every direction through the kingdom, enjoined by the court, to secure, at whatever expense of torture, a return to Catholicism. One of the tortures which these merciless fanatics were fond of applying was to deprive their victim of sleep. They kept the sufferer standing, and relieved each other in their cruel work of pinching, pricking, twitching, pulling with ropes, burning, suffocating with offensive fumes, until after successive days and nights of torture the victim was driven to madness, and to promise any thing to escape from his tormentors. By these means, it was boasted that in the district of Bordeaux, where there were one hundred and fifty thousand Protestants, one hundred and forty thousand were converted in a fortnight. The Duke of Noailles wrote to the court that in the district to which he had been sent with his dragoons there had been two hundred and forty thousand Protestants, but he thought that by the end of the month none could be left. In the year 1598 Henry IV., by the Edict of Nantes, had granted freedom of conscience and of worship to the Protestants. Louis XIV. now issued a decree revoking this edict. The revocation, which was signed the 18th of October, 1685, states in the preamble that "since the better and the greater part of our subjects of the pretended reformed religion have embraced the Catholic faith, the maintenance of the Edict of Nantes remains superfluous." It then declares that no more exercise of the reformed worship is to be tolerated in the realm. All the Protestant pastors were to leave the kingdom within fifteen days, and were forbidden to exercise their office under pain of the galleys. Parents were forbidden to instruct their children in the reformed faith, and were enjoined to send them to the Catholic church to be baptized and to be instructed in the Catholic schools and catechism, under penalty of a fine of five hundred livres. The Protestant laity were prohibited from emigrating under pain of the galleys for the men, and imprisonment for life for the women. Notwithstanding the penalty, vast numbers escaped from the kingdom. No vigilance could guard such extended frontiers. In one year after the revocation, Vauban wrote that France had lost one hundred thousand inhabitants, twelve thousand disciplined soldiers, six hundred officers, and her most flourishing manufactures. The Duke of St. Simon records that "a fourth part of the kingdom was perceptibly depopulated." These crimes perpetrated against religion filled the land with infidelity. There were even Catholics of noble name and note, as Fénélon and Massillon, who energetically remonstrated. Montesquieu, Voltaire, Rousseau, and Mirabeau, not distinguishing between Christianity and the Papal Church, uttered cries of indignation which thrilled upon the ear of Europe and undermined the foundations of Christianity itself.
