“The night of the pretended execution of the Duke of Monmouth, the king, attended by three men, came to the Tower and summoned the duke to his presence. A kind of loose cowl was thrown over his head, and he was put into a carriage, into which the king and his attendants also got, and was driven away.”

Sainte-Foix also referred to the alleged visit of Saunders, confessor to James II, paid to the Duchess of Portsmouth after the death of that monarch, when the duchess took occasion to say that she could never forgive King James for consenting to Monmouth’s execution, in spite of the oath he had taken on the sacred elements at the deathbed of Charles II that he would never take his natural brother’s life, even in case of rebellion. To this the priest replied quickly, “The king kept his oath.”

Hume also records this solemn oath, but we cannot say that all the historians agree on this point. ‘The Universal History’ by Guthrie and Gray, and the ‘Histoire d’Angleterre’ by Rapin, Thoyras and de Barrow, do not mention it.

“Further,” wrote Sainte-Foix, “an English surgeon called Nelaton, who frequented the Cafe Procope, much affected by men of letters, often related that during the time he was senior apprentice to a surgeon who lived near the Porte Saint-Antoine, he was once taken to the Bastille to bleed a prisoner. He was conducted to this prisoner’s room by the governor himself, and found the patient suffering from violent headache. He spoke with an English accent, wore a gold-flowered dressing-gown of black and orange, and had his face covered by a napkin knotted behind his head.”

This story does not hold water: it would be difficult to form a mask out of a napkin; the Bastille had a resident surgeon of its own as well as a physician and apothecary; no one could gain access to a prisoner without a written order from a minister, even the Viaticum could only be introduced by the express permission of the lieutenant of police.

This theory met at first with no objections, and seemed to be going to oust all the others, thanks, perhaps, to the combative and restive character of its promulgator, who bore criticism badly, and whom no one cared to incense, his sword being even more redoubtable than his pen.

It was known that when Saint-Mars journeyed with his prisoner to the Bastille, they had put up on the way at Palteau, in Champagne, a property belonging to the governor. Freron therefore addressed himself to a grand-nephew of Saint-Mars, who had inherited this estate, asking if he could give him any information about this visit. The following reply appeared in the ‘Annee Litteraire (June 1768):—

“As it appears from the letter of M. de Sainte-Foix from which you quote that the Man in the Iron Mask still exercises the fancy of your journalists, I am willing to tell you all I know about the prisoner. He was known in the islands of Sainte-Marguerite and at the Bastille as ‘La Tour.’ The governor and all the other officials showed him great respect, and supplied him with everything he asked for that could be granted to a prisoner. He often took exercise in the yard of the prison, but never without his mask on. It was not till the ‘Siecle’ of M. de Voltaire appeared that I learned that the mask was of iron and furnished with springs; it may be that the circumstance was overlooked, but he never wore it except when taking the air, or when he had to appear before a stranger.

“M. de Blainvilliers, an infantry officer who was acquainted with M. de Saint-Mars both at Pignerol and Sainte-Marguerite, has often told me that the lot of ‘La Tour’ greatly excited his curiosity, and that he had once borrowed the clothes and arms of a soldier whose turn it was to be sentry on the terrace under the prisoner’s window at Sainte-Marguerite, and undertaken the duty himself; that he had seen the prisoner distinctly, without his mask; that his face was white, that he was tall and well proportioned, except that his ankles were too thick, and that his hair was white, although he appeared to be still in the prime of life. He passed the whole of the night in question pacing to and fro in his room. Blainvilliers added that he was always dressed in brown, that he had plenty of fine linen and books, that the governor and the other officers always stood uncovered in his presence till he gave them leave to cover and sit down, and that they often bore him company at table.

“In 1698 M. de Saint-Mars was promoted from the governorship of the Iles Sainte-Marguerite to that of the Bastille. In moving thither, accompanied by his prisoner, he made his estate of Palteau a halting-place. The masked man arrived in a litter which preceded that of M. de Saint-Mars, and several mounted men rode beside it. The peasants were assembled to greet their liege lord. M. de Saint-Mars dined with his prisoner, who sat with his back to the dining-room windows, which looked out on the court. None of the peasants whom I have questioned were able to see whether the man kept his mask on while eating, but they all noticed that M. de Saint-Mars, who sat opposite to his charge, laid two pistols beside his plate; that only one footman waited at table, who went into the antechamber to change the plates and dishes, always carefully closing the dining-room door behind him. When the prisoner crossed the courtyard his face was covered with a black mask, but the peasants could see his lips and teeth, and remarked that he was tall, and had white hair. M. de Saint-Mars slept in a bed placed beside the prisoner’s. M. de Blainvilliers told me also that ‘as soon as he was dead, which happened in 1704, he was buried at Saint-Paul’s,’ and that ‘the coffin was filled with substances which would rapidly consume the body.’ He added, ‘I never heard that the masked man spoke with an English accent.’”
