Stair wished, above all, to hinder the Regent from giving any assistance to the Pretender, and to prevent him passing through the realm in order to reach a seaport. Now the Regent was between two stools, for he had promised the Pretender to wink at his doings, and to favour his passage through France, if it were made secretly, and at the same time he had assented to the demand of Stair. Things had arrived at this pass when the troubles increased in England, and the Earl of Mar obtained some success in Scotland. Soon after news came that the Pretender had departed from Bar, and was making his way to the coast. Thereupon Stair ran in hot haste to M. le Duc d’Orleans to ask him to keep his promise, and hinder the Pretender’s journey. The Regent immediately sent off Contade, major in the guards, very intelligent, and in whom he could trust, with his brother, a lieutenant in the same regiment, and two sergeants of their choice, to go to Chateau-Thierry, and wait for the Pretender, Stair having sure information that he would pass there. Contade set out at night on the 9th of November, well resolved and instructed to miss the person he was to seek. Stair, who expected as much, took also his measures, which were within an inch of succeeding; for this is what happened.
The Pretender set out disguised from Bar, accompanied by only three or four persons, and came to Chaillot, where M. de Lauzun had a little house, which he never visited, and which he had kept for mere fancy, although he had a house at Passy, of which he made much use. It was in this, Chaillot’s house, that the Pretender put up, and where he saw the Queen, his mother, who often stopped at the Convent of the Filles de Sainte Marie-Therese. Thence he set out in a post-chaise of Torcy’s, by way of Alencon, for Brittany, where he meant to embark.
Stair discovered this scheme, and resolved to leave nothing undone in order to deliver his party of this, the last of the Stuarts. He quietly despatched different people by different roads, especially by that from Paris to Alencon. He charged with this duty Colonel Douglas (who belonged to the Irish (regiments) in the pay of France), who, under the protection of his name, and by his wit and his intrigues, had insinuated himself into many places in Paris since the commencement of the regency; had placed himself on a footing of consideration and of familiarity with the Regent; and often came to my house. He was good company; had married upon the frontier of Metz; was very poor; had politeness and much experience of the world; the reputation of distinguished valour; and nothing which could render him suspected of being capable of a crime.
