This mark of fidelity might have proved fatal to Caesar: when the pope heard how his messenger had been treated, he flew into such a rage that the prisoner thought a second time that his hour was come;and in order to receive his liberty, he made the first of those new propositions to Julius II, which were drawn up in the form of a treaty and sanctioned by a bull.By these arrangements, the Duke of Valentinois was bound to hand over to His Holiness, within the space of forty days, the fortresses of Cesena and Bertinoro, and authorise the surrender of Forli.This arrangement was guaranteed by two bankers in Rome who were to be responsible for 15,000 ducats, the sum total of the expenses which the governor pretended he had incurred in the place on the duke's account.The pope on his part engaged to send Caesar to Ostia under the sole guard of the Cardinal of Santa Croce and two officers, who were to give him his full liberty on the very day when his engagements were fulfilled: should this not happen, Caesar was to be taken to Rome and imprisoned in the Castle of Sant'
Angelo.In fulfilment of this treaty, Caesar went down the Tiber as far as Ostia, accompanied by the pope's treasurer and many of his servants.The Cardinal of Santa Croce followed, and the next day joined him there.
But as Caesar feared that Julius II might keep him a prisoner, in spite of his pledged word, after he had yielded up ,the fortresses, he asked, through the mediation of Cardinals Borgia and Remolina, who, not feeling safe at Rome, had retired to Naples, for a safe-conduct to Gonzalva of Cordova, and for two ships to take him there;with the return of the courier the safe-conduct arrived, announcing that the ships would shortly follow.
In the midst of all this, the Cardinal of Santa Croce, learning that by the duke's orders the governors of Cesena and Bertinoro had surrendered their fortresses to the captains of His Holiness, relaxed his rigour, and knowing that his prisoner would some day or other be free, began to let him go out without a guard.Then Caesar, feeling some fear lest when he started with Gonzalvo's ships the same thing might happen as on the occasion of his embarking on the pope's vessel--that is, that he might be arrested a second time--concealed himself in a house outside the town; and when night came on, mounting a wretched horse that belonged to a peasant, rode as far as Nettuno, and there hired a little boat, in which he embarked for Monte Dragone, and thence gained Naples.Gonzalvo received him with such joy that Caesar was deceived as to his intention, and this time believed that he was really saved.His confidence was redoubled when, opening his designs to Gonzalvo, and telling him that he counted upon gaining Pisa and thence going on into Romagna, Ganzalva allowed him to recruit as many soldiers at Naples as he pleased, promising him two ships to embark with.Caesar, deceived by these appearances, stopped nearly six weeks at Naples, every day seeing the Spanish governor and discussing his plans.But Gonzalvo was only waiting to gain time to tell the King of Spain that his enemy was in his hands; and Caesar actually went to the castle to bid Gonzalvo good-bye, thinking he was just about to start after he had embarked his men on the two ships.The Spanish governor received him with his accustomed courtesy, wished him every kind of prosperity, and embraced him as he left; but at the door of the castle Caesar found one of Gonzalvo's captains, Nuno Campeja by name, who arrested him as a prisoner of Ferdinand the Catholic.Caesar at these words heaved a deep sigh, cursing the ill luck that had made him trust the word of an enemy when he had so often broken his own.
He was at once taken to the castle, where the prison gate closed behind him, and he felt no hope that anyone would come to his aid;for the only being who was devoted to him in this world was Michelotto, and he had heard that Michelotto had been arrested near Pisa by order of Julius II.While Caesar was being taken to prison an officer came to him to deprive him of the safe-conduct given him by Gonzalvo.
The day after his arrest, which occurred on the 27th of May, 1504, Caesar was taken on board a ship, which at once weighed anchor and set sail for Spain: during the whole voyage he had but one page to serve him, and as soon as he disembarked he was taken to the castle of Medina del Campo.
Ten years later, Gonzalvo, who at that time was himself proscribed, owned to Loxa on his dying bed that now, when he was to appear in the presence of God, two things weighed cruelly on his conscience: one was his treason to Ferdinand, the other his breach of faith towards Caesar.
