Saved by the intelligence and devotion of the post-mistress of Nonancourt, he embarked on the 26th of December at Dunkerque, too late to bring even moral support to the men who were fighting and dying for him.

Six weeks after landing at Peterhead, in Scotland, he started back again without having struck a blow, without having set eyes upon the enemy, leaving to King George I.the easy task of avenging himself by sending to death upon the scaffold the noblest victims.

The Duke of Orleans had given him a little money, had known of and had encouraged his passage through France, but had accorded him no effectual aid; the wrath of both parties, nevertheless, fell on him.
Inspired by Dubois, weary of the weakness and dastardly incapacity of the Pretender, the Regent consented to make overtures to the King of England.
The Spanish nation was favorable to France, but the king was hostile to the Regent; the English loved neither France nor the Regent, but their king had an interest in severing France from the Pretender forever.
Dubois availed himself ably of his former relations with Lord Stanhope, heretofore commander of the English troops in Spain, for commencing a secret negotiation which soon extended to Holland, still closely knit to England.

"The character of our Regent," wrote Dubois on the 10th of March, 1716, "leaves no ground for fearing lest he should pique himself upon perpetuating the prejudices and the procedure of our late court, and, as you yourself remark, he has too much wit not to see his true interest." Dubois was the bearer to the Hague of the Regent's proposals; King George was to cross over thither; the clever negotiator veiled his trip under the pretext of purchasing rare books; he was going, he said, to recover from the hands of the Jews Le Poussin's famous pictures of the Seven Sacraments, not long ago carried off from Paris.

The order of succession to the crowns of France and England, conformably to the peace of Utrecht, was guaranteed in the scheme of treaty; that was the only important advantage to the Regent, who considered himself to be thus nailing the renunciation of Philip V.; in other respects all the concessions came from the side of France; her territory was forbidden ground to the Jacobites, and the Pretender, who had taken refuge at Avignon on papal soil, was to be called upon to cross the Alps.
