Having got this document, Marsilly's captors took it to the French Ministers. Nothing could be more embarrassing, if this were true, to Charles's representative in France, Montague, and to Charles's secret negotiations, also to Arlington, who had dealt with Marsilly. On his part, the captive Marsilly constantly affirmed that he was the envoy of the King of England. The common talk of Paris was that an agent of Charles was in the Bastille, "though at Court they pretended to know nothing of it." Louis was overjoyed at Marsilly's capture, giving out that he was conspiring against his life. Monsieur told Montague that he need not beg for the life of a would-be murderer like Marsilly. But as to this idea, "they begin now to mince it at Court," and Ruvigny assured du Moulin "that they had no such thoughts." De Lyonne had seen Marsilly and observed that it was a blunder to seize him. The French Government was nervous, and Turenne's secretary had been "pumping" several ambassadors as to what they thought of Marsilly's capture on foreign territory. One ambassador replied with spirit that a crusade of all Europe against France, as of old against the Moslems, would be necessary. Would Charles, du Moulin asked, own or disown Marsilly?
Montague's position was now awkward. On May 23, his account of the case was read, at Whitehall, to the Foreign Committee in London.
(See Note II. for the document.) He did not dare to interfere in Marsilly's behalf, because he did not know whether the man was an agent of Charles or not. Such are the inconveniences of a secret royal diplomacy carried on behind the backs of Ministers. Louis XV. later pursued this method with awkward consequences.[1] The French Court, Montague said, was overjoyed at the capture of Marsilly, and a reward of 100,000 crowns, "I am told very privately, is set upon his head." The French ambassador in England, Colbert, had reported that Charles had sent Marsilly "to draw the Swisses into the Triple League" against France. Montague had tried to reassure Monsieur (Charles's brother-in-law), but was himself entirely perplexed. As Monsieur's wife, Charles's sister, was working with Charles for the secret treaty with Louis, the State and family politics were clearly in a knot. Meanwhile, the Spanish ambassador kept pressing Montague to interfere in favor of Marsilly. After Montague's puzzled note had been read to the English Foreign Committee on May 23, Arlington offered explanations. Marsilly came to England, he said, when Charles was entering into negotiations for peace with Holland, and when France seemed likely to oppose the peace. No proposition was made to him or by him. Peace being made, Marsilly was given money to take him out of the country. He wanted the King to renew his alliance with the Swiss cantons, but was told that the cantons must first expel the regicides of Charles I. He undertook to arrange this, and some eight months later came back to England. "He was coldly used, and I was complained of for not using so important a man well enough."

As we saw, Marsilly expressed the most effusive gratitude to Arlington, which does not suggest cold usage. Arlington told the complainers that Marsilly was "another man's spy," what man's, Dutch, Spanish, or even French, he does not explain. So Charles gave Marsilly money to go away. He was never trusted with anything but the expulsion of the regicides from Switzerland. Arlington was ordered by Charles to write a letter thanking Balthazar for his good offices.
These explanations by Arlington do not tally with Marsilly's communications to him, as cited at the beginning of this inquiry.
Nothing is said in these about getting the regicides of Charles I. out of Switzerland: the paper is entirely concerned with bringing the Protestant Cantons into anti-French League with England, Holland, Spain, and even Sweden. On the other hand, Arlington's acknowledged letter to Balthazar, carried by Marsilly, may be the "commission" of which Marsilly boasted. In any case, on June 2, Charles gave Colbert, the French ambassador, an audience, turning even the Duke of York out of the room. He then repeated to Colbert the explanations of Arlington, already cited, and Arlington, in a separate interview, corroborated Charles. So Colbert wrote to Louis (June 3, 1669); but to de Lyonne, on the same day, "I trust that you will extract from Marsilly much matter for the King's service. It seemed to me that milord d'Arlington was uneasy about it [en avait de l'inquitetude]. . . . There is here in England one Martin" (Eustace Dauger), "who has been that wretch's valet, and who left him discontent." Colbert then proposes to examine Martin, who may know a good deal, and to send him into France. On June 10, Colbert writes to Louis that he expects to see Martin.[1]

On June 24, Colbert wrote to Louis about a conversation with Charles. It is plain that proofs of a murder-plot by Marsilly were scanty or non-existent, though Colbert averred that Marsilly had discussed the matter with the Spanish Ministers. "Charles knew that he had had much conference with Isola, the Spanish ambassador." Meanwhile, up to July 1, Colbert was trying to persuade Marsilly's valet to go to France, which he declined to do, as we have seen. However, the luckless lad, by nods and by veiled words, indicated that he knew a great deal. But not by promise of security and reward could the valet be induced to return to France.
"I might ask the King to give up Martin, the valet of Marsilly, to me," Colbert concludes, and, by hook or by crook, he secured the person of the wretched man, as we have seen. In a postcript, Colbert says that he has heard of the execution of Marsilly.
