On landing at Calais, they traveled post to Paris, strictly preserving their incognito, but assuming such an air and bearing as to create the impression that they were not what they pretended. When they reached Paris, Buckingham could not resist the temptation of showing Charles a little of life, and he contrived to get admitted to a party at court, where Charles saw, among other ladies who attracted his attention, the Princess Henrietta. He was much struck with her beauty and grace, but he little thought that it was this princess, and not the Infanta whom he was going in pursuit of, who was really to become his wife, and the future Queen of England. [Sidenote: Bourdeaux.] The young travelers thought it not prudent to remain long in Paris, and they accordingly left that city, and pressed forward as rapidly as possible toward the Spanish frontier. They managed, however, to conduct always in such a way as to attract attention. Although they were probably sincerely desirous of not having their true rank and character known, still they could not resist the temptation to assume such an air and bearing as to make people wonder who they were, and thus increase the spirit and adventure of their journey. At Bourdeaux they received invitations from some grandees to be present at some great gala, but they declined, saying that they were only poor gentlemen traveling to inform their minds, and were not fit to appear in such gay assemblies. [Sidenote: Entrance into Madrid.] At last they approached Madrid. They had, besides Collington, another attendant who spoke the Spanish language, and served them as an interpreter. They separated from these two the day before they entered Madrid, so as to attract the less attention. Their attendants were to be left behind for a day, and afterward were to follow them into the city. The name of the British embassador at Madrid was the Earl of Bristol. He had had charge of all the negotiations in respect to the marriage, and to the restoration of the Palatinate, and believed that he had brought them almost to a successful termination. He lived in a palace in Madrid, and, as is customary with the embassadors of great powers at the courts of great powers, in a style of the highest pomp and splendor. [Sidenote: Bristol's amazement.] [Sidenote: Charles's reception.] Buckingham took the prince directly to Bristol's house. Bristol was utterly confounded at seeing them. Nothing could be worse, he said, in respect to the completion of the treaty, than the prince's presence in Madrid. The introduction of so new and extraordinary an element into the affair would undo all that had been done, and lead the King of Spain to begin anew, and go over all the ground again. In speaking of this occurrence to another, he said that just as he was on the point of coming to a satisfactory conclusion of his long negotiations and toils, a demon in the shape of Prince Charles came suddenly upon the stage to thwart and defeat them all.
