In October, 1505, Ferdinand, who had already recalled Gonsalvo de Cordova from Naples and decided to supplant him with his own son Alfonso of Aragon, Archbishop of Saragossa, determined, owing to his lieutenant’s uncertain attitude, to go to Naples himself. The ten days Gonsalvo had asked to put the defences in order and arrange his affairs had elapsed and the King’s suspicions were strengthened. It was then that he conceived the idea of using Caesar to crush Gonsalvo. Thereupon he dispatched Don Pedro de Ayala to Philippe le Beau at Medina del Campo to demand his prisoner, saying that he intended to confine him in the Castle of Ejerica until he was ready to go to Naples, when he would take him with him to command his troops. Fate apparently was about to afford Caesar an exquisite revenge; he was to lead a Spanish army against the man who had deceived him and delivered him into the hands of the Catholic monarch. Philippe le Beau, however, had his own plans regarding Caesar, and while Ferdinand desired to avail himself of his services against Gonsalvo and Julius II., Maximilian’s son conceived the idea of using him against the Catholic sovereign himself in case he persisted in claiming the regency. From these circumstances it is clear that Caesar’s ability and energy as a military leader were universally recognised. To lend greater authority to his refusal to surrender Caesar, Philippe le Beau stated that he would first have to refer the matter to the Council of Castile to determine whether the Duke was the prisoner of the King or of Queen Jeanne. In apprehending him in Naples Gonsalvo indubitably was acting in the interests of the kingdom of which Philippe was Regent for his wife, the legitimate heir. Moreover, the Duke would have to be held a prisoner until the suit instituted by the Duchess of Gandia was decided. Ferdinand did not give up the fight when informed of the Council’s decision, but requested Don Bernardino de Cardenas, Governor of the province of Grenada, to whose care he had committed Caesar, to surrender his prisoner. Cardenas was disposed to obey, but asked permission of the Regent, who absolutely refused to allow Caesar to be given up. The Governor then explained to the King that even if he freed Valentino, Philippe would at once seize him again as he did not have a sufficient force to oppose the Regent.
