The marriage of Prince Edward with the Lady Anne was immediately celebrated in France.
Edward foresaw that it would be easy to dissolve an alliance composed of such discordant parts.

For this purpose, he sent over a lady of great sagacity and address, who belonged to the train of the duchess of Clarence, and who, under color of attending her mistress, was empowered to negotiate with the duke, and to renew the connections of that prince with his own family.[*] She represented to Clarence, that he had unwarily, to his own ruin, become the instrument of Warwick's vengeance, and had thrown himself entirely in the power of his most inveterate enemies; that the mortal injuries which the one royal family had suffered from the other, were now past all forgiveness, and no imaginary union of interests could ever suffice to obliterate them; that even if the leaders were willing to forget past offences, the animosity of their adherents would prevent a sincere coalition of parties, and would, in spite of all temporary and verbal agreements, preserve an eternal opposition of measures between them; and that a prince who deserted his own kindred, and joined the murderers of his father, left himself single, without friends, without protection, and would not, when misfortunes inevitably fell upon him, be so much as entitled to any pity or regard from the rest of mankind.

Clarence was only one and twenty years of age, and seems to have possessed but a slender capacity; yet could he easily see the force of these reasons; and, upon the promise of forgiveness from his brother, he secretly engaged, on a favorable opportunity, to desert the earl of Warwick, and abandon the Lancastrian party.
During this negotiation, Warwick was secretly carrying on a correspondence of the same nature with his brother, the marquis of Montague, who was entirely trusted by Edward; and like motives produced a like resolution in that nobleman.
