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.* 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 favour 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.’ *Cf. Le Secret du Roi, by the Duc de Broglie. 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.
