he had at his immediate disposal a hundred squadrons of heavy cavalry, twenty men in each, and three thousand bowmen and light horse.  He proposed, therefore, to advance at once into Lombardy, to get up a revolution in favour of his nephew Galeazzo, and to drive Ludovico Sforza out of Milan before he could get help from France; so that Charles viii, at the very time of crossing the Alps, would find an enemy to fight instead of a friend who had promised him a safe passage, men, and money.

This was the scheme of a great politician and a bold commander; but as everybody had came in pursuit of his own interests, regardless of the common this plan was very coldly received by Piero dei Medici, who was afraid lest in the war he should play only the same poor part he had been threatened with in the affair of the embassy; by Alexander vi it was rejected, because he reckoned on employing the troops of Alfonso an his own account.  He reminded the King of Naples of one of the conditions of the investiture he had promised him, viz. that he should drive out the Cardinal Giuliano delta Rovere from the town of Ostia, and give up the town to him, according to the stipulation already agreed upon.  Besides, the advantages that had accrued to Virginio Orsini, Alexander’s favourite, from his embassy to Naples had brought upon him the ill-will of Prospero and Fabrizio Colonna, who owned nearly all the villages round about Rome.  Now the pope could not endure to live in the midst of such powerful enemies, and the most important matter was to deliver him from all of them, seeing that it was really of moment that he should be at peace who was the head and soul of the league whereof the others were only the body and limbs.

Although Alfonso had clearly seen through the motives of Piero’s coldness, and Alexander had not even given him the trouble of seeking his, he was none the less obliged to bow to the will of his allies, leaving the one to defend the Apennines against the French, and helping the other to shake himself free of his neighbours in the Romagna.  Consequently he, pressed on the siege of Ostia, and added to Virginio’s forces, which already amounted to two hundred men of the papal army, a body of his own light horse; this little army was to be stationed round about Rome, and was to enforce obedience from the Colonnas.  The rest of his troops Alfonso divided into two parties:  one he left in the hands of his son Ferdinand, with orders to scour the Romagna and worry, the petty princes into levying and supporting the contingent they had promised, while with the other he himself defended the defiles of the Abruzzi.

On the 23rd of April, at three o’clock in the morning, Alexander vi was freed from the first and fiercest of his foes; Giuliano delta Rovere, seeing the impossibility of holding out any longer against Alfonso’s troops, embarked on a brigantine which was to carry him to Savona.
