wrote, "the sweetest creature in France. Her growth is very little short of her age, and her wisdom infinitely beyond it. I heard her discourse with her mother and the ladies about her with extraordinary discretion and quickness. She dances (the which I am a witness of) as well as ever I saw any creature. They say she sings very sweetly. I am sure she looks so."[6] To the Duke of Buckingham, who at this time entirely governed Charles' mind, he wrote an equally enthusiastic account, praising the Princess as a "lovely sweet young creature," who, if she was not tall in stature, was "perfect in shape."[7]

Marriage negotiations between royal persons are always lengthy, and in this case there was the additional difficulty of the difference of religion between the contracting parties, which necessitated a dispensation from the Pope. But James of England eagerly desired the alliance, seeing in it a means of winning back the Palatinate for his daughter's husband, a hope which was encouraged by the diplomacy of Richelieu, who probably also worked upon the mind of Mary de' Medici, so that, in spite of her bigoted attachment to the Roman Catholic Church, the whole weight of her now powerful influence was thrown on the side of the marriage. Father Bérulle, the founder of the French Oratory, who was a great friend of hers, was sent to Rome to procure a dispensation from Urban VIII. Arrangements were made to secure Henrietta's religion and morals in the heretic country to which she was going, and it was provided that she should have the bringing up of her children until they reached the age of twelve years. Finally, secret articles[8] were inserted in the marriage treaty, in which James of England and his son promised that toleration should be granted to the English Catholics. Everything seemed settled, and all was rejoicing both in England and France, except for two malcontents: the Spanish Ambassador in Paris stood sullenly aloof, "who, without question, doth not well like that England and France should bee joyned together with such a firme alliance,"[9] and the Count of Soissons was so angry and disappointed at the loss of his bride that he refused to treat Lord Kensington with common courtesy, savagely declaring that the negotiations went so near his heart that were the Englishman not the ambassador of so great a King, he would cut his throat.

Henrietta herself was well pleased, and her cheerful countenance reflected her content. She exchanged a number of quaint and rather formal love-letters with her future husband, who sometimes employed as his intermediary a young protégé of Buckingham, by name Walter Montagu, who was destined to a singular career and to a lifelong friendship with the Princess, whom he now saw for the first time. In March, 1625, he left Paris and returned to England carrying the good news that all was forward, and that the lady should be delivered in thirty days. He was able to supplement Holland's description of the charms of the Princess, for, like that nobleman, he was something of a connoisseur in such matters. "I have made the Prince in love with every hair on Madame's head,"[10] he wrote cheerfully to Carlisle. So eager was the bridegroom that he would not allow the match to be stayed for the final settlement of the details of the dispensation.

But just as everything was ready an event of another character occurred to retard matters again. On March 27th, 1625, King James died, and the question arose as to whether the wedding could be celebrated during the period of mourning. However, as Henrietta could hardly be expected to feel acutely the death of an unknown father-in-law which made her a queen, and as Charles' impatience for his bride overcame any scruples with regard to decorum, it was settled that the great event should take place in the ensuing May. The decision that the bridegroom should not be present in person at the ceremony was probably a disappointment to Henrietta. It had been suggested that he should come over to France, but the proposal had not met with approval on either side of the Channel, the English thinking it beneath their King's dignity to seek his bride in a foreign land, and the French fearing, with good reason, the expense of such a guest. The selection of a proxy caused some difficulty. Charles wished that his great friend, the Duke of Buckingham, should impersonate him on this interesting occasion, but that nobleman, for private reasons which will be explained below, was not agreeable to the French Court. The choice finally fell upon the Duke of Chevreuse,[11] who was at once a high-born Frenchman and a relative of the King of England, being a prince of the House of Lorraine, and thus connected with Charles' great-grandmother, Mary of Guise. In spite of his high rank he was a person of sufficient obscurity, and chiefly remarkable as the husband of his brilliant wife.

The betrothal was solemnized on May 8th, which happened to be the Feast of the Ascension. The ceremony took place in the Louvre in the King's own room, which was elaborately fitted up for the occasion, and where, in the late afternoon, he appeared as (we are told) "a beautiful sun which shines above all others."[12] Lesser lights were present in the persons of his wife, his only brother Gaston, Duke of Orleans, and a crowd of noblemen, all of whom waited impatiently for the bride-elect, who at last appeared, attended by her mother and by Madame de Chevreuse. Henrietta entered the room with a dignity worthy of the occasion and of the great race from which she was sprung. Her magnificent dress, which perhaps a little eclipsed her girlish beauty, consisted of a robe of cloth of gold and silver thickly sprinkled with golden fleurs-de-lis and enriched by diamonds and other precious stones. This wonderful garment was further adorned by a long train carried by the little Mademoiselle de Bourbon, the Madame de Longueville of later days, who at this time was so young that she could only nominally fulfil her office, while the long, heavy folds were really supported by Madame de Montglas' daughter, Madame S. Georges, who was to accompany the young Queen to England.

Henrietta's entry was followed by that of the two English Ambassadors and the proxy bridegroom. Then, after the signing and countersigning of the articles of marriage, the betrothal ceremony was solemnized according to the rites of the Church by Cardinal de Rochefoucault, Grand Almoner of the King of France. In the evening a ball was held in the Louvre, while outside the firing of cannon and the letting off of fireworks testified to the public
