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. Meanwhile, Florence was being harrowed, and that was all to Cesare’s satisfaction and advantage. When sufficiently humbled, it might well befall that the Republic should come on her knees to implore his intervention, and his pardon for having flouted him.
While matters stood so in Arezzo, Pisa declared spontaneously for Cesare, and sent (on June 10) to offer herself to his dominion and to announce to him that his banner was already flying from her turrets—and the growth of Florence’s alarm at this is readily conceived.
To Cesare it must have been a sore temptation. To accept such a pied-à-terre in Tuscany as was now offered him would have been the first great step towards founding that kingdom of his dreams. An impulsive man had surely gulped the bait. But Cesare, boundless in audacity, most swift to determine and to act, was not impulsive. Cold reason, foresight and calculation were the ministers of his indomitable will. He looked ahead and beyond in the matter of Pisa’s offer, and he perceived the danger that might await him in the acceptance. The time for that was not yet. To take what Pisa offered might entail offending France, and although Cesare was now in case to dispense with French support, he was in no case to resist her opposition.
And so, the matter being considered and determined, Cesare quitted Rome on the 12th and left it for the Pope to give answer to the Pisan envoys in the Consistory of June 14—that neither his Holiness nor the Duke of Valentinois could assent to the proposals which Pisa made.
From Rome Cesare travelled swiftly to Spoleto, where his army, some ten thousand strong, was encamped. He was bent at last upon the conquest of Camerino, and, ever an opportunist, he had seized the moment when Florence, which might have been disposed to befriend Varano, Tyrant of Camerino, was over-busy with her own affairs.
In addition to the powerful army awaiting him at Spoleto, the duke had a further 2,000 men in the Romagna; another 1,000 men held themselves at his orders between Sinigaglia and Urbino, and Dionigio di Naldo was arming yet another 1,000 men at Verucchio for his service. Yet further to increase this force, Cesare issued an edict during his brief sojourn at Spoleto ordering every house in the Romagna to supply him with one man-at-arms.
It was whilst here—as he afterwards wrote to the Pope—that news reached him that Guidobaldo da Montefeltre, Duke of Urbino, was arming men and raising funds for the assistance of Camerino. He wrote that he could not at first believe it, but that shortly afterwards—at Foligni—he took a chancellor of Camerino who admitted that the hopes of this State were all founded upon Urbino’s assistance; and later, a messenger from Urbino falling into his hands, he discovered that there was a plot afoot to seize the Borgia artillery as it passed through Ugubio, it being known that, as Cesare had no suspicions, the guns would be guarded only by a small force. Of this treachery the duke strongly expressed his indignation in his letter to the Pope.
Whether the matter was true—or whether Cesare believed it to be true—it is impossible to ascertain with absolute conviction. But it is in the highest degree unlikely that Cesare would have written such a letter to his father solely by way of setting up a pretext. Had that been his only aim, letters expressing his simulated indignation would have been in better case to serve his ends had they been addressed to others.
