As was to be expected, Visconti again failed to fulfil the conditions of the treaty, and within three years hostilities broke out again. To the amazement and mortification of the Venetian government, however, Carmagnola now resigned his commission, almost at the moment when he was to have taken command, and there is reason to believe that he was even then secretly negotiating with Visconti. But the Republic could not afford to lose such a man at such a moment; he was offered conditions which must have surpassed even his own tolerably large expectations. Not only was he to possess for himself and all his descendants the great estate of Chiari, with its rental, but another large feudal holding in the territory of Brescia was promised him on the same conditions; if all Lombardy were taken, he was promised the complete restitution of all the domains which Visconti had formerly bestowed upon him; all plunder and all prisoners of war were to be his, the Republic contracting to pay him a certain sum for each prisoner of importance whom he handed over to the government; as if this were not enough, he was to be crowned Duke of Milan if he could drive out Visconti. While these astonishing offers were being made to him by Venice, he received more than one letter from the Duke, requesting him to act as an intermediary to make peace. This fact was, of course, soon known to the Venetian government, and we can hardly be surprised that the Venetians should not have liked the part which the Duke was thrusting upon a man who had betrayed him, and whom he should have considered as his worst enemy. [Sidenote: _H. Brown, Ven. Studies, 165._] Mr. Horatio Brown has conjectured with great acumen that Visconti, who thoroughly understood the character of Carmagnola, as well as that of the Venetian government, chose the surest means of ruining the condottiero of whom he wished to be rid. Carmagnola, equally flattered by the Duke’s secret letters and by the overwhelming offers of the Republic, began to assume airs of superiority which could not but excite the suspicion of a government whereof suspicion itself was the very foundation and mainspring. A series of discussions now began between the Senate and Visconti, in which Carmagnola was continually concerned, but it was soon the gossip of the city that the letters which he really sent to the Duke were by no means identical with the drafts of those which he showed the Senate for approbation. It is at least certain that, after war was declared, as was inevitable, Carmagnola showed neither decision nor energy when obliged to face Visconti’s army, and allowed himself to be beaten by Francesco Sforza, who was afterwards himself Duke of Milan. He showed all his old energy in Friuli in driving out the Hungarians, whom Visconti had induced to make a descent upon that territory, but he had no sooner come back to Brescia, for which Visconti himself was fighting, than his hesitation returned.
