Faithful to his engagements, Pius iii replied that in his quality of sovereign prince the duke in his temporal administration was quite independent and was answerable for his actions to God alone.

But as the pope felt he could not much longer support Caesar against his enemies for all his goodwill, he advised him to try to join the French army, which was still advancing on Naples, in the midst of which he would alone find safety.  Caesar resolved to retire to Bracciano, where Gian Giordano Orsino, who had once gone with him to France, and who was the only member of the family who had not declared against him, offered him an asylum in the name of Cardinal dumbest:  so one morning he ordered his troops to march for this town, and, taking his place in their midst, he left Rome.

But though Caesar had kept his intentions quiet, the Orsini had been forewarned, and, taking out all the troops they had by the gate of San Pancracio, they had made along detour and blocked Caesar’s way; so, when the latter arrived at Storta, he found the Orsini’s army drawn up awaiting him in numbers exceeding his own by at least one-half.

Caesar saw that to come to blows in his then feeble state was to rush on certain destruction; so he ordered his troops to retire, and, being a first-rate strategist, echelonned his retreat so skilfully that his enemies, though they followed, dared not attack him, and he re-entered the pontifical town without the loss of a single man.

This time Caesar went straight to the Vatican, to put himself more directly under the pope’s protection; he distributed his soldiers about the palace, so as to guard all its exits.  Now the Orsini, resolved to make an end of Caesar, had determined to attack him wheresoever he might be, with no regard to the sanctity of the place:  this they attempted, but without success, as Caesar’s men kept a good guard on every side, and offered a strong defence.

Then the Orsini, not being able to force the guard of the Castle Sant’ Angelo, hoped to succeed better with the duke by leaving Rome and then returning by the Torione gate; but Caesar anticipated this move, and they found the gate guarded and barricaded.  None the less, they pursued their design, seeking by open violence the vengeance that they had hoped to obtain by craft; and, having surprised the approaches to the gate, set fire to it:  a passage gained, they made their way into the gardens of the castle, where they found Caesar awaiting them at the head of his cavalry.

Face to face with danger, the duke had found his old strength:  and he was the first to rush upon his enemies, loudly challenging Orsino in the hope of killing him should they meet; but either Orsino did not hear him or dared not fight; and after an exciting contest, Caesar, who was numerically two-thirds weaker than his enemy, saw his cavalry cut to pieces; and after performing miracles of personal strength and courage, was obliged to return to the Vatican.  There he found the pope in mortal agony:  the Orsini, tired of contending against the old man’s word of honour pledged to the duke, had by the interposition of Pandolfo Petrucci, gained the ear of the pope’s surgeon, who placed a poisoned plaster upon a wound in his leg.
