The Prince de Conti was his chief early patron, and it was originally in support of Conti's ambition to be King of Poland that Louis XV. began his incredibly foolish 'secret'--a system of foreign policy conducted by hidden agents behind the backs of his responsible ministers at Versailles and in the Courts of Europe. The results naturally tend to recall a Gilbert and Sullivan comic opera of diplomacy. We find magnificent ambassadors gravely trying to carry out the royal orders, and thwarted by the King's secret agents. The King seems to have been too lazy to face his ministers, and compel them to take his own line, while he was energetic enough to work like Tiberius or Philip II. of Spain at his secret Penelope's task of undoing by night the warp and woof which his ministers wove by day. In these mysterious labours of his the Comte de Broglie, later a firm friend of d'Eon, was, with Tercier, one of his main assistants. The King thus enjoyed all the pleasures and excitements of a conspirator in his own kingdom, dealing in ciphered despatches, with the usual cant names, carried in the false bottoms of snuff-boxes, precisely as if he had been a Jacobite plotter. It was entertaining, but it was not diplomacy, and, sooner or later, Louis was certain to be 'blackmailed' by some underling in his service. That underling was to be d'Eon. In 1755 Louis wished to renew relations, long interrupted, with Elizabeth, Empress of Russia, the lady whom Prince Charlie wanted to marry, and from whose offered hand the brave James Keith fled as fast as horses could carry him. Elizabeth, in 1755, was an ally of England, but was known to be French in her personal sympathies, though she was difficult of access. As a messenger, Louis chose a Scot, described by Captain Buchan Telfer as a Mackenzie, a Jesuit, calling himself the Chevalier Douglas, and a Jacobite exile. He is not to be found in the _Dictionary of National Biography_. A Sir James and a Sir John Douglas--if both were not the same man--were employed as political agents between the English and Scottish Jacobites in 1746, and, in 1749, between the Prince and the Landgrave of Hesse. Whatever the true name of the Douglas of Louis XV., I suspect that he was one or the other of these dim Jacobites of the Douglas clan. In June 1755 this Chevalier Douglas was sent by Louis to deal with Elizabeth. He was certainly understood by Louis to be a real Douglas, a fugitive Jacobite, and he was to use in ciphered despatches precisely the same silly sort of veiled language about the fur trade as Prince Charles's envoys had just been using about 'the timber trade' with Sweden.
