Arezzo followed this up by summoning Vitelli, and the waiting, watchful condottiero was quick to answer the desired call.

He entered the town three days later at the head of a small body of foot, and was very shortly afterwards followed by his brother Giulio Vitelli, Bishop of Citta di Castello, with the artillery, and, presently, by Gianpaolo Baglioni with a condotta of horse.
A few days later Vitelli was in possession of all the strongholds of the Val di Chiana, and panic-stricken Florence was speeding ambassadors hot-foot to Rome to lay her complaints of these matters before the Pope.
Alexander was able to reply that, far from supporting the belligerents, he had launched a Bull against them, provoked by the poisoning of the Bishop de'Pazzi.
Cesare looked on with the inscrutable calm for which Macchiavelli was presently to find him so remarkable.

Aware as he was of the French protection which Florence enjoyed and could invoke, he perceived how vain must ultimately prove Vitelli's efforts, saw, perhaps, in all this the grave danger of ultimate ruin which Vitelli was incurring.

Yet Vitelli's action served Cesare's own purposes, and, so that his purposes were served, there were no other considerations likely to weigh with that cold egotist.

Let Vitelli be caught in the toils he was spinning, and be choked in them.
