But as the league between the Florentines and the Venetians still continued, and as the king, after the war of Piombino, had made peace with the former, it seemed indecent to commence an open rupture until some plausible reason could be assigned in justification of offensive measures. On this account each sent ambassadors to Florence, who, on the part of their sovereigns, signified that the league formed between them was made not for injury to any, but solely for the mutual defense of their states. The Venetian ambassador then complained that the Florentines had allowed Alessandro, the duke's brother, to pass into Lombardy with his forces; and besides this, had assisted and advised in the treaty made between the duke and the marquis of Mantua, matters which he declared to be injurious to the Venetians, and inconsistent with the friendship hitherto subsisting between the two governments; amicably reminding them, that one who inflicts unmerited injury, gives others just ground of hostility, and that those who break a peace may expect war. The Signory appointed Cosmo de' Medici to reply to what had been said by the Venetian ambassador, and in a long and excellent speech he recounted the numerous advantages conferred by the city on the Venetian republic; showed what an extent of dominion they had acquired by the money, forces, and counsel of the Florentines, and reminded him that, although the friendship had originated with the Florentines, they had never given occasion of enmity; and as they desired peace, they greatly rejoiced when the treaty was made, if it had been entered into for the sake of peace, and not of war. True it was, he wondered much at the remarks which had been made, seeing that such light and trivial matters should give offense to so great a republic; but if they were worthy of notice he must have it universally understood, that the Florentines wished their country to be free and open to all; and that the duke's character was such, that if he desired the friendship of the marquis of Mantua, he had no need of anyone's favor or advice. He therefore feared that these cavils were produced by some latent motive, which it was not thought proper to disclose. Be this as it might, they would freely declare to all, that in the same proportion as the friendship of the Florentines was beneficial their enmity could be destructive.

The matter was hushed up; and the ambassadors, on their departure, appeared perfectly satisfied. But the league between the king and the Venetians made the Florentines and the duke rather apprehend war than hope for a long continuance of peace. They therefore entered into an alliance, and at the same time the enmity of the Venetians transpired by a treaty with the Siennese, and the expulsion of all Florentine subjects from their cities and territories. Shortly after this, Alfonso did the same, without any consideration of the peace made the year previous, and not having even the shadow of an excuse. The Venetians attempted to take Bologna, and having armed the emigrants, and united to them a considerable force, introduced them into the city by night through one of the common sewers. No sooner had they entered, than they raised a cry, by which Santi Bentivogli, being awakened, was told that the whole city was in possession of the rebels. But though many advised him to escape, saying that he could not save the city by his stay, he determined to confront the danger, and taking arms encouraged his followers, assembled a few friends, attacked and routed part of the rebels, slew many more, and drove the remainder out of the city. By this act of bravery all agreed he had fully proved himself a genuine scion of the house of the Bentivogli.

These events and demonstrations gave the Florentines an earnest of approaching war; they consequently followed their usual practice on similar occasions, and created the Council of Ten. They engaged new condottieri, sent ambassadors to Rome, Naples, Venice, Milan, and Sienna, to demand assistance from their friends, gain information about those they suspected, decide such as were wavering, and discover the designs of the foe. From the pope they obtained only general expressions of an amicable disposition and admonitions to peace; from the king, empty excuses for having expelled the Florentines, and offers of safe conduct for whoever should demand it; and although he endeavored, as much as possible, to conceal every indication of his hostile designs, the ambassadors felt convinced of his unfriendly disposition, and observed many preparations tending to the injury of the republic. The League with the duke was strengthened by mutual obligations, and through his means they became friends with the Genoese, the old differences with them respecting reprisals, and other small matters of dispute, being composed, although the Venetians used every possible means to prevent it, and entreated the emperor of Constantinople to expel all Florentines from his dominions; so fierce was the animosity with which they entered on this war, and so powerful their lust of dominion, that without the least hesitation they sought the destruction of those who had been the occasion of their own power. The emperor, however, refused to listen to them. The Venetian senate forbade the Florentine ambassadors to enter their territories, alleging, that being in league with the king, they could not entertain them without his concurrence. The Siennese received the ambassadors with fair words, fearing their own ruin before the League could assist them, and therefore endeavored to appease the powers whose attack they were unable to resist. The Venetians and the king (as was then conjectured) were disposed to send ambassadors to Florence to justify the war. But the Venetian envoy was not allowed to enter the Florentine dominions, and the king's ambassador, being unwilling to perform his office alone, the embassy was not completed; and thus the Venetians learned, that however little they might esteem the Florentines, the latter had still less respect for them.

In the midst of these fears, the emperor, Frederick III., came into Italy to be crowned. On the thirtieth of January, 1451, he entered Florence with fifteen hundred horse, and was most honorably received by the Signory. He remained in the city till the sixth of February, and then proceeded to Rome for his coronation, where, having been solemnly consecrated, and his marriage celebrated with the empress, who had come to Rome by sea, he returned to Germany, and again passed through Florence in May, with the same honors as upon his arrival. On his return, having derived some benefits from the marquis of Mantua, he conceded to him Modena and Reggio. In the meantime, the Florentines did not fail to prepare themselves for immediate war; and to augment their influence, and strike the enemy with terror, they, in conjunction with the duke, entered into alliance with the king of France for the mutual defense of their states. This treaty was published with great pomp throughout all Italy.

The month of May, 1452, having arrived, the Venetians thought it not desirable to defer any longer their attack upon the duke, and with sixteen thousand horse and six thousand foot assailed his territories in the direction of Lodi, while the marquis of Montferrat, instigated either by his own ambition or the entreaties of the Venetians, did the same on the side of Alexandria. The duke assembled a force of eighteen thousand cavalry and three thousand infantry, garrisoned Alexandria and Lodi, and all the other places where the enemy might annoy them. He then attacked the Brescian territory, and greatly harassed the Venetians; while both parties alike plundered the country and ravaged the smaller towns. Having defeated the marquis of Montferrat at Alexandria, the duke was able to unite his whole force against the Venetians and invade their territory.
