'The king having thought fit to send to the château of St. André de Salins some of the people who were arrested in virtue of warrants of the court that dealt with the matter of the poisons, his Majesty has commanded me to inform you that his intention is that you prepare two rooms in the said château, so that six of these prisoners may be kept safely in each of them, the which prisoners are to have each a mattress in the place arranged for them, and to be fastened either by a hand or a foot to a chain which shall be fastened to the wall, the said chain however to be long enough not to prevent them from lying down. As these people are criminals who deserve extreme penalties, the intention of the king is that they be thus fastened for fear they should injure the people set to guard them, who will go in and out to bring them food and attend to them generally. His Majesty's intention is that you prepare two similar rooms in the citadel of Besançon, so that twelve of the prisoners may be kept securely there. You will observe that these rooms are to be so situated that no one can hear what these people say.' Auzillon, one of the staff of the provost of the Isle de France, escorted the principal sorceresses, Pelletier, Poulain, Delaporte, the girl Monvoisin, and Catherine Leroy, to the citadel of Belle-Isle-en-Mer. La Chappelain, the companion of La Filastre, was imprisoned in the castle of Villefranche, where she died forty years later, on June 4, 1724. She lived there in company with another sorceress who, like her, had been withdrawn from the jurisdiction of the Chambre Ardente, and for the same reasons--namely, La Guesdon. The governor of Villefranche wrote in August 1717, that 'of two old prisoners of state for poison, the survivors of four who had been locked up there for thirty-six years, La Guesdon died on the 15th instant, leaving forty-five livres in silver, which she had saved during that time out of her eight sous a day for food: of these she instructed her surviving companion to take what she needed for her personal use, and to use the balance in paying for prayers for her--this is one pensioner the less for the king. The woman was seventy-six years old; the survivor (La Chappelain) is no younger. They were in the same room.' Finally, a few prisoners at the Bastille and Vincennes, wholly ignorant of the poison affair, and others whose innocence was recognised by the commissioners of the Chambre Ardente, had been shut up, unluckily for themselves, in the same room with prisoners implicated in the crimes of Madame de Montespan. This chance meeting condemned them to perpetual confinement. 'Manon Bosse,' writes La Reynie, 'was sent to the nuns of Baffens, at Besançon, under the name of Mademoiselle Manon Dubosc, where the king pensioned her to the tune of 250 livres; she was never liberated, because she had been locked up with the daughter of La Voisin, who had told her everything.'
