Gaston had withdrawn from the Court after the birth of the two Princes; and although he had, with his usual pusillanimity, continued to preserve an apparently good understanding with the Cardinal, few were deceived into the belief that this ostensible oblivion of the past was genuine. Monsieur was, when the subject of the new cabal against Richelieu was mooted to him by Cinq-Mars, residing in the Luxembourg (known at that period as the Palais d'Orléans), whither the Grand Equerry was accustomed to repair in disguise, and generally during the night, to concert with the Prince all the preliminaries of the conspiracy. Gaston, as had been anticipated, evinced no indisposition to lend himself to the views of Cinq-Mars and his friends,[235] when they eventually assured him that they had certain information of the efforts which the Cardinal was at that very period making to secure his own nomination to the regency of the kingdom, in the event of the then-pending journey to Catalonia, whither Louis was about to proceed early in the ensuing spring, to swear to the inviolate preservation of the ancient laws and privileges of the Catalans; and at the same time to endeavour to possess himself of the province of Roussillon, although the infirm state of his health would have appeared to render such an expedition too hazardous to be contemplated at such a season. Like his successor Louis XIV, the son of Marie de Medicis was one of the most "unamusable" of monarchs; and like Cinq-Mars himself, he was weary of the unvaried routine of pleasures which made up the sum of his existence while confined to his own capital; and thus he welcomed every prospect of change without caring to investigate the motives of those by whom it was proposed. He did not, therefore, for an instant suspect that the motive of his ambitious minister in urging him to undertake upon the instant, and in a state of excessive bodily suffering, an expedition which might with safety have been deferred until a more genial season, was in reality to remove him to a distance from the Parliament and the citizens of Paris, and to place him between two armies, both of which were commanded by Richelieu's own near relatives and devoted friends, in order that should the already exhausted strength of the invalid sovereign fail him under the fatigue and privation of so severe an exertion, the Cardinal might cause himself to be declared Regent of the kingdom after his death.
