Marsilly was publicly tortured to death in Paris on June 22, 1669. By July 19 his ex-valet, Dauger, had entered on his mysterious term of captivity. How the French got possession of him, whether he yielded to cajolery, or was betrayed by Charles II., is uncertain. The French ambassador at St. James's, Colbert (brother of the celebrated Minister), writes thus to M. de Lyonne, in Paris, on July I, 1669:[1] "Monsieur Joly has spoken to the man Martin" (Dauger), "and has really persuaded him that, by going to France and telling all that he knows against Roux, he will play the part of a lad of honor and a good subject." [1] Transcripts from Paris MSS., Vol. xxxiii., Record Office. But Martin, after all, was NOT persuaded! Martin replied to Joly that he knew nothing at all, and that, once in France, people would think he was well acquainted with the traffickings of Roux, "and so he would be kept in prison to make him divulge what he did not know." The possible Man in the Iron Mask did not know his own secret! But, later in the conversation, Martin foolishly admitted that he knew a great deal; perhaps he did this out of mere fatal vanity. Cross to France, however, he would not, even when offered a safe-conduct and promise of reward. Colbert therefore proposes to ask Charles to surrender the valet, and probably Charles descended to the meanness. By July 19, at all events, Louvois, the War Minister of Louis XIV., was bidding Saint- Mars, at Pignerol in Piedmont, expect from Dunkirk a prisoner of the very highest importance--a valet! This valet, now called "Eustache Dauger," can only have been Marsilly's valet, Martin, who, by one means or another, had been brought from England to Dunkirk. It is hardly conceivable, at least, that when a valet, in England, is "wanted" by the French police on July 1, for political reasons, and when by July 19 they have caught a valet of extreme political importance, the two valets should be two different men. Martin must be Dauger. Here, then, by July 19, 1669, we find our unhappy serving man in the toils. Why was he to be handled with such mysterious rigor? It is true that State prisoners of very little account were kept with great secrecy. But it cannot well be argued that they were all treated with the extraordinary precautions which, in the case of Dauger, were not relaxed for twenty-five or thirty years. The King says, according to Louvois, that the safe keeping of Dauger is "of the last importance to his service." He must have intercourse with nobody. His windows must be where nobody can pass; several bolted doors must cut him off from the sound of human voices. Saint-Mars himself, the commandant, must feed the valet daily. "You must never, under any pretenses listen to what he may wish to tell you. You must threaten him with death if he speaks one word except about his actual needs. He is only a valet, and does not need much furniture."[1]
