The residence at Koeur-la-Petite lasted for five years, 1465-69. The peaceful home was broken up through the treachery of the turbulent and self-seeking Earl of Warwick. Exasperated with Edward IV., owing to his marriage and connexion with the Woodville faction, Warwick had resolved to abandon the cause with which he was connected by ties of relationship and by life-long service. He had married his daughter Isabel to the Duke of Clarence without the King's consent, and had alienated that vacillating prince from his brother. He came to France with the Countess, his two daughters Isabel and Anne, and Clarence: and proposed to King Louis to espouse the cause of his cousin Margaret, and to restore Henry to the throne. The fear of an alliance between Edward IV. and the Duke of Burgundy caused Louis to entertain Warwick's scheme. But it was most distasteful to Margaret. Much as she {67} longed for the restoration to her child of his birthright, she found it difficult to accept such aid. Warwick had not only been the most inveterate enemy of her family, he had also made himself personally odious to Margaret. He was now a double-dyed traitor. His motives were transparently selfish, and she believed neither in his new-born loyalty nor in his ability to help her. But the persuasions of Louis XI. and of her own relations at length induced her to come to the French court. The Queen and her son, attended by Sir John Fortescue and their other faithful adherents, left the happy home in the lovely valley of the Meuse in December 1469. Margaret arrived at Tours, where the French court then was, accompanied by Prince Edward, King René, her brother John of Calabria, her sister Iolanthe, and her brother-in-law Ferry de Vaudemont. Warwick arrived soon afterwards, and with much reluctance Margaret consented to an interview. Negotiations were continued for several months; and on July 15 the court moved to Angers, where the Countess of Warwick and her daughter Anne were in attendance. Warwick asked that Prince Edward should marry his daughter Anne, as the reward of his assistance. At first the Queen positively refused, but she at last gave a conditional and very unwilling assent, moved by the importunities of Louis XI. and her relations. The marriage was not to take place until after Henry VI. was restored to the throne and, if Warwick failed, the agreement was at an end. 'The said marriage shall not be perfyted until the Earl of Warwick has recovered the realm of England for King Henry.'[7] They were never married. They {68} were, indeed, too young, Edward being seventeen, and Anne barely fourteen.[8] Knowing the dislike of his mother to such a union, and strongly prejudiced against it himself, it is not likely that Edward ever took more notice of Warwick's child than ordinary courtesy required, if indeed he ever saw her.
