to Lucca, spreading a report that it was his intention to go to Naples to render assistance to the king of Aragon.  Upon these new events Pope Eugenius left Florence and proceeded to Bologna, where he endeavored to effect an amicable arrangement between the league and the duke, intimating to the latter, that if he would not consent to some treaty, the pontiff must send Francesco Sforza to assist the league, for the latter was now his confederate, and served in his pay.  Although the pope greatly exerted himself in this affair, his endeavors were unavailing; for the duke would not listen to any proposal that did not leave him the possession of Genoa, and the league had resolved that she should remain free; and, therefore, each party, having no other resource, prepared to continue the war.

In the meantime Niccolo Piccinino arrived at Lucca, and the Florentines, being doubtful what course to adopt, ordered Neri di Gino to lead their forces into the Pisan territory, induced the pontiff to allow Count Francesco to join him, and with their forces they halted at San Gonda.  Piccinino then demanded admission into the kingdom of Naples, and this being refused, he threatened to force a passage.  The armies were equal, both in regard of numbers and the capacity of their leaders, and unwilling to tempt fortune during the bad weather, it being the month of December, they remained several days without attacking each other.  The first movement was made by Niccolo Piccinino, who being informed that if he attacked Vico Pisano by night, he could easily take possession of the place, made the attempt, and having failed, ravaged the surrounding country, and then burned and plundered the town of San Giovanni alla Vena.  This enterprise, though of little consequence, excited him to make further attempts, the more so from being assured that the count and Neri were yet in their quarters, and he attacked Santa Maria in Castello and Filetto, both which places he took.  Still the Florentine forces would not stir; not that the count entertained any fear, but because, out of regard to the pope, who still labored to effect an accommodation, the government of Florence had deferred giving their final consent to the war.  This course, which the Florentines adopted from prudence, was considered by the enemy to be only the result of timidity, and with increased boldness they led their forces up to Barga, which they resolved to besiege.  This new attack made the Florentines set aside all other considerations, and resolve not only to relieve Barga, but to invade the Lucchese territory.  Accordingly the count proceeded in pursuit of Niccolo, and coming up with him before Barga, an engagement took place, in which Piccinino was overcome, and compelled to raise the siege.

The Venetians considering the duke to have broken the peace, send Giovan Francesco da Gonzaga, their captain, to Ghiaradadda, who, by severely wasting the duke’s territories, induced him to recall Niccolo Piccinino from Tuscany.  This circumstance, together with the victory obtained over Niccolo, emboldened the Florentines to attempt the recovery of Lucca, since the duke, whom alone they feared, was engaged with the Venetians, and the Lucchese having received the enemy into their city, and allowed him to attack them, would have no ground of complaint.
