At this time, ambassadors came to Florence from the emperor, the king of France, and the king of Hungary, who were sent by their princes to the pontiff. They solicited the Florentines also to send ambassadors to the pope, and promised to use their utmost exertion to obtain for them an advantageous peace. The Florentines did not refuse to make trial, both for the sake of publicly justifying their proceedings, and because they were really desirous of peace. Accordingly, the ambassadors were sent, but returned without coming to any conclusion of their differences. The Florentines, to avail themselves of the influence of the king of France, since they were attacked by one part of the Italians and abandoned by the other, sent to him as their ambassador, Donato Acciajuoli, a distinguished Latin and Greek scholar, whose ancestors had always ranked high in the city, but while on his journey he died at Milan. To relieve his surviving family and pay a deserved tribute to his memory, he was honorably buried at the public expense, provision was made for his sons, and suitable marriage portions given to his daughters, and Guid' Antonio Vespucci, a man well acquainted with pontifical and imperial affairs, was sent as ambassador to the king in his stead.
The attack of Signor Roberto upon the Pisan territory, being unexpected, greatly perplexed the Florentines; for having to resist the foe in the direction of Sienna, they knew not how to provide for the places about Pisa. To keep the Lucchese faithful, and prevent them from furnishing the enemy either with money or provisions, they sent as ambassador Piero di Gino Capponi, who was received with so much jealousy, on account of the hatred which that city always cherishes against the Florentines from former injuries and constant fear, that he was on many occasions in danger of being put to death by the mob;and thus his mission gave fresh cause of animosity rather than of union. The Florentines recalled the marquis of Ferrara, and engaged the marquis of Mantua; they also as earnestly requested the Venetians to send them Count Carlo, son of Braccio, and Deifobo, son of Count Jacopo, and after many delays, they complied; for having made a truce with the Turks, they had no excuse to justify a refusal, and could not break through the obligation of the League without the utmost disgrace. The counts, Carlo and Deifobo, came with a good force, and being joined by all that could be spared from the army, which, under the marquis of Ferrara, held in check the duke of Calabria, proceeded toward Pisa, to meet Signor Roberto, who was with his troops near the river Serchio, and who, though he had expressed his intention of awaiting their arrival, withdrew to the camp at Lunigiana, which he had quitted upon coming into the Pisan territory, while Count Carlo recovered all the places that had been taken by the enemy in that district.
The Florentines, being thus relieved from the attack in the direction of Pisa, assembled the whole force between Colle and Santo Geminiano.
