The French court now began to change their scheme with regard to the subjection of Brittany. Charles had formerly been affianced to Margaret, daughter of Maximilian; who, though too young for the consummation of her marriage, had been sent to Paris to be educated, and at this time bore the title of queen of France. Besides the rich dowry which she brought the king, she was, after her brother Philip, then in early youth, heir to all the dominions of the house of Burgundy; and seemed in many respects the most proper match that could be chosen for the young monarch. These circumstances had so blinded both Maximilian and Henry, that they never suspected any other intentions in the French court; nor were they able to discover that engagements, seemingly so advantageous and so solemnly entered into, could be infringed and set aside. But Charles began to perceive that the conquest of Brittany, in opposition to the natives, and to all the great powers of Christendom, would prove a difficult enterprise; and that even if he should overrun the country and make himself master of the fortresses, it would be impossible for him long to retain possession of them. The marriage alone of the duchess could fully reannex that fief to the crown; and the present and certain enjoyment of so considerable a territory, seemed preferable to the prospect of inheriting the dominions of the house of Burgundy; a prospect which became every day more distant and precarious. Above all, the marriage of Maximilian and Anne appeared destructive to the grandeur and even security of the French monarchy; while that prince, possessing Flanders on the one hand, and Brittany on the other, might thus, from both quarters, make inroads into the heart of the country. The only remedy for these evils was therefore concluded to be the dissolution of the two marriages, which had been celebrated, but not consummated; and the espousal of the duchess of Brittany by the king of France.
