Caesar thought at first that, breaking his word as he had so often done himself, Prospero Colonna was going to attack him.  He ordered a halt, and prepared to mount his horse; but Prospera Colonna, seeing the state he was in, advanced to his bedside alone:  he came, against expectation, to offer him an escort, fearing an ambuscade on the part of Fabio Orsino, who had loudly sworn that he would lose his honour or avenge the death of Paolo Orsina, his father.  Caesar thanked Colanna, and replied that from the moment that Orsini stood alone he ceased to fear him.  Then Colonna saluted the duke, and rejoined his men, directing them towards Albano, while Caesar took the road to Citta Castellana, which had remained loyal.

When there, Caesar found himself not only master of his own fate but of others as well:  of the twenty-two votes he owned in the Sacred College twelve had remained faithful, and as the Conclave was composed in all of thirty-seven cardinals, he with his twelve votes could make the majority incline to whichever side he chose.  Accordingly he was courted both by the Spanish and the French party, each desiring the election of a pope of their own nation.  Caesar listened, promising nothing and refusing nothing:  he gave his twelve votes to Francesco Piccolomini, Cardinal of Siena, one of his father’s creatures who had remained his friend, and the latter was elected on the 8th of October and took the name of Pius iii.

Caesar’s hopes did not deceive him:  Pius iii was hardly elected before he sent him a safe-conduct to Rome:  the duke came back with 250 men-at-arms, 250 light horse, and 800 infantry, and lodged in his palace, the soldiers camping round about.

Meanwhile the Orsini, pursuing their projects of vengeance against Caesar, had been levying many troops at Perugia and the neighbourhood to bring against him to Rome, and as they fancied that France, in whose service they were engaged, was humouring the duke for the sake of the twelve votes which were wanted to secure the election of Cardinal Amboise at the next Conclave, they went over to the service of Spain.

Meanwhile Caesar was signing a new treaty with Louis XII, by which he engaged to support him with all his forces, and even with his person, so soon as he could ride, in maintaining his conquest of Naples:  Louis, on his side, guaranteed that he should retain possession of the States he still held, and promised his help in recovering those he had lost.

The day when this treaty was made known, Gonzalvo di Cordovo proclaimed to the sound of a trumpet in all the streets of Rome that every Spanish subject serving in a foreign army was at once to break his engagement on pain of being found guilty of high treason.

This measure robbed Caesar of ten or twelve of his best officers and of nearly 300 men.

Then the Orsini, seeing his army thus reduced, entered Rome, supported by the Spanish ambassador, and summoned Caesar to appear before the pope and the Sacred College and give an account of his crimes.
