But what troubled the prelate more than this insolence of his general, was a letter which fell into his hands, addressed by the king to Count Navarro, in which he requested him to be sure to find some pretence for detaining the cardinal in Africa, as long as his presence could be made any way serviceable. Ximenes had good reason before to feel that the royal favor to him flowed from selfishness, rather than from any personal regard. The king had always wished the archbishopric of Toledo for his favorite, and natural son, Alfonso of Aragon. After his return from Naples, he importuned Ximenes to resign his see, and exchange it for that of Saragossa, held by Alfonso; till, at length, the indignant prelate replied, "that he would never consent to barter away the dignities of the church; that if his Highness pressed him any further, he would indeed throw up the primacy, but it should be to bury himself in the friar's cell from which the queen had originally called him." Ferdinand, who, independently of the odium of such a proceeding, could ill afford to part with so able a minister, knew his inflexible temper too well ever to resume the subject. [17]
With some reason, therefore, for distrusting the good-will of his sovereign, Ximenes put the worst possible construction on the expressions in his letter. He saw himself a mere tool in Ferdinand's hands, to be used so long as occasion might serve, with the utmost indifference to his own interests or convenience. These humiliating suspicions, together with the arrogant bearing of his general, disgusted him with the further prosecution of the expedition; while he was confirmed in his purpose of returning to Spain, and found an obvious apology for it in the state of his own health, too infirm to encounter, with safety, the wasting heats of an African summer.
Before his departure, he summoned Navarro and his officers about him, and, after giving them much good counsel respecting the government and defence of their new acquisitions, he placed at their disposal an ample supply of funds and stores, for the maintenance of the army several months. He then embarked, not with the pompous array and circumstance of a hero returning from his conquests, but with a few domestics only, in an unarmed galley, showing, as it were, by this very act, the good effects of his enterprise, in the security which it brought to the before perilous navigation of these inland seas.
