Bedford found for the moment an able and vigorous successor in the Duke of York. Richard of York was the son of the Earl of Cambridge who had been beheaded by Henry the Fifth; his mother was Anne, the heiress of the Mortimers and of their claim to the English crown as representatives of the third son of Edward the Third, Lionel of Clarence. It was to assert this claim on his son's behalf that the Earl embarked in the fatal plot which cost him his head. But his death left Richard a mere boy in the wardship of the Crown, and for years to come all danger from his pretensions was at an end. Nor did the young Duke give any sign of a desire to assert them as he grew to manhood. He appeared content with a lineage and wealth which placed him at the head of the English baronage; for he had inherited from his uncle the Dukedom of York, his wide possessions embraced the estates of the families which united in him, the houses of York, of Clarence, and of Mortimer, and his double descent from Edward the Third, if it did no more, set him near to the Crown. The nobles looked up to him as the head of their order, and his political position recalled that of the Lancastrian Earls at an earlier time. But the position of Richard was as yet that of a faithful servant of the Crown; and as Regent of France he displayed the abilities both of a statesman and of a general. During the brief space of his regency the tide of ill fortune was stemmed; and towns and castles were recovered along the border. [Sidenote: Eleanor Cobham]
