However, in one way Wolsey had a right to feel satisfaction even in his ill-success. If money was not to be had, war was impossible, and Wolsey might now pursue his own policy and work for peace. He had to face the actual facts that England was allied to Charles, who had won a signal victory over Francis, and had in his hands a mighty hostage in the person of the King of France. His first object was to discover Charles V.'s intentions, and prevent him from using his advantage solely for his own profit. Bishop Tunstal and Sir Richard Wingfield were sent to Charles with orders to put on a bold face, and find whether Charles thought of dethroning Francis or releasing him for a ransom. In the first case, they were to offer military aid from England; in the second, they were to claim for England a large share in the concessions to be wrung out of Francis. The English demands were so exorbitant that though they may have satisfied the fantastic aspirations of Henry, Wolsey must have known them to be impossible. Under cover of a friendly proposal to Charles he was really preparing the way for a breach. Charles on his side was engaged in playing a similar game. In spite of his success at Pavia he was really helpless. He had no money, and the captivity of the French king awakened so much alarm in Europe that he felt compelled to use his advantage moderately. As a first measure he needed money, and saw no chance of obtaining it save by marrying Isabella of Portugal, who would bring him a dowry of 1,000,000 golden crowns. For this purpose he must free himself from the engagement of the treaty of Windsor, by which he was betrothed to Mary of England. So he acted as Wolsey was acting. He professed a great desire to carry out his engagement as a means of getting rid of it, and sent ambassadors to ask that Mary and her dowry should be given up to him, with a further loan of 200,000 ducats.
