Profiting by the retreat of the Maréchal de Bois-Dauphin, the Duc de Bouillon had made all haste to pass the Loire, and to reach the confines of Touraine and Poitou; nor would it have been possible for their Majesties to have reached Bordeaux in safety, had it not been for the secession of the Comte de Saint-Pol from the faction of the Princes, together with the impossibility of marching the rebel troops upon Poitou in so short a space of time. Thanks to this combination of circumstances, however, the Court arrived without accident in the capital of Guienne on the 7th of October; where the King and his august mother were received with great magnificence, and enthusiastically welcomed by all classes of the citizens, whom the Maréchal de Roquelaure, lieutenant-general for the King in Guienne, and Mayor of Bordeaux, had adroitly gained, by his representations of the honour conferred upon them by the sovereign in selecting their city as the scene of his own marriage and that of his sister, the future Queen of Spain.[208] It had been arranged that the royal marriages should be celebrated on the same day (the 18th of October), at Bordeaux and Burgos; and accordingly the Duc de Guise, as proxy for the Prince of Spain, espoused Madame Elisabeth, with whom, accompanied by the Duchesse de Nevers and the ladies of her household, he immediately departed for the frontier, after a painful leave-taking between the young Princess and her family; while the Duque d'Usseda[209] performed the same ceremony for Louis XIII, with the Infanta Anna Maria of Austria. The exchange of the two Princesses took place on the 9th of November, in the middle of the Bidassoa, with a host of petty and futile observances which excite mirth rather than admiration; but at the same time with a magnificence surpassing all that had ever previously been exhibited on such an occasion; the two Courts of France and Spain vying with each other in splendour and profusion. De Luynes, to whom such a mission appeared peculiarly adapted, presented to the Infanta the letters of welcome with which he had been entrusted by Louis XIII and his mother, and which were received by the Princess with an undisguised delight that the favourite did not fail to report to his royal master.
