Louis was busied with his own affairs in Touraine when news came to him that the marriage was to take place immediately. "If he mourned, it is not marvellous when I myself mourn it for the future result. But the king used all kinds of machinations to break off the alliance.... God suffered two young proud princes to try their strength each at his will, often in ways that would have been incompatible in common affairs."

The fullest account of the wedding is given by La Marche, an eyewitness of the event:[7]

"Gilles du Mas, maître d'hôtel du Duc de Bretagne—to you I recommend myself. I have collected here roughly according to my stupid understanding what I saw of the said festival, to send it to you, beseeching you as earnestly as I can to advise me of the noble states and high deeds in your quarter ... as becomes two friends of one rank and calling in two fraternal, allied and friendly houses.

"My lady and her company arrived at l'Écluse on a Saturday, June 25th, and on the morrow Madame the Duchess of Burgundy, mother of the duke, Mlle. of Burgundy and various other ladies and demoiselles visited Madame Margaret [8] and only stayed till dinner. The duchess was greatly pleased with her prospective daughter-in-law and could not say enough of her character and her virtues. There remained with Dame Margaret, on the part of the duchess, the Charnys, Messire Jehan de Rubempré and various other ladies and gentlemen to act the hosts to the strange ladies and gentlemen who had crossed from England with the bride. The Count and Countess de Charny met Madame as she disembarked and never budged from her side until she had arrived at Bruges.

"The day after the duchess's visit, Monseigneur of Burgundy made his way to l'Écluse with a small escort and entered the chateau at the rear. After supper, accompanied only by six or seven knights of the Order, he went very secretly to the hôtel of Dame Margaret, who had been warned of his intention, and was attended by the most important members of her suite, such as the Seigneur d'Escalles, the king's brother.

"At his arrival when they saw each other the greetings were very ceremonious and then the two sat down on one bench and chatted comfortably together for some time. After some conversation, the Bishop of Salisbury, according to a prearranged plan of his own, kneeled before the two and made complimentary speeches. He was followed by M. de Charny, who spoke as follows:

"'Monseigneur, you have found what you desired and since God has brought this noble lady to port in safety and to your desire, it seems to me that you should not depart without proving the affection you bear her, and that you ought to be betrothed now at this moment and give her your troth.'

"Monseigneur answered that it did not depend upon him. Then the bishop spoke to Margaret and asked her what she thought. She answered that it was just for this and nothing else that the king of England had sent her over and she was quite ready to fulfil the king's command. Whereupon the bishop took their hands and betrothed them. Then Monseigneur departed and returned on the morrow to Bruges.

"Dame Margaret remained at l'Écluse until the following Saturday and was again visited by Monseigneur. On Saturday the boats were richly decorated to conduct my lady to Damme, where she was received very honourably according to the capacity of that little town. On the morrow, the 3rd of July, Monseigneur the duke set out with a small escort between four and five o'clock in the morning, and went to Damme, where he found Madame quite ready to receive him as all had been prearranged, and Monseigneur wedded her as was suitable, and the nuptial benediction was duly pronounced by the Bishop of Salisbury. After the mass, Charles returned to his hotel at Bruges, and you may believe that during the progress of the other ceremonies he slept as if he were to be on watch on the following night.

"Immediately after, Adolph of Cleves, John of Luxemburg, John of Nassau, and others returned to Damme and paid their homage to the new duchess, and then my lady entered a horse litter, beautifully draped with cloth of gold. She was clad in white cloth of gold made like a wedding garment as was proper. On her hair rested a crown and her other jewels were appropriate and sumptuous. Her English ladies followed her on thirteen hackneys, two close by her litter and the others behind. Five chariots followed the thirteen hackneys, the Duchess of Norfolk, the most beautiful woman in England, being in the first. In this array Madame proceeded to Bruges and entered at the gate called Ste. Croix."
