What really called him back was more than his passion for Eleanor Cobham or the natural versatility of his temper; it was the advance of a rival in England to further power over the realm. This was his uncle, Henry Beaufort, Bishop of Winchester. The bishop had already played a leading political part. He was charged with having spurred Henry the Fifth to the ambitious demands of power which he made during his father's lifetime; he became chancellor on his accession; and at his death the king left him guardian of the person of his boy. He looked on Gloucester's ambition as a danger to his charge, withstood his recognition as Regent, and remained at the head of the Council that reduced his office of Protector to a name. The Duke's absence in Hainault gave fresh strength to his opponent: and the nomination of the Bishop to the Chancellorship marked him out as the virtual ruler of the realm. On the news of this appointment Gloucester hurried back to accept what he looked on as a challenge to open strife. The Londoners rose in his name to attack Beaufort's palace in Southwark, and at the close of 1425 Bedford had to quit his work in France to appease the strife. In the following year Gloucester laid a formal bill of accusation against the bishop before the Parliament, but its rejection forced him to a show of reconciliation, and Bedford was able to return to France. Hardly was he gone however when the quarrel began anew. Humphrey found a fresh weapon against Beaufort in his acceptance of the dignity of a Cardinal and of a Papal Legate in England; and the jealousy which this step aroused drove the Bishop to withdraw for a while from the Council and to give place to his unscrupulous opponent.
