The concluding words of the Florentine exiles produced the utmost excitement among the Venetian senators, and they resolved to send Bernardo Coglione, their general, to attack the Florentine territory. The troops were assembled, and joined by Ercole da Esti, who had been sent by Borgo, marquis of Ferrara. At the commencement of hostilities, the Florentines not being prepared, their enemies burned the Borgo of Dovadola, and plundered the surrounding country.

Hereupon the Florentines intimated to the duke, that his presence with the force was in many ways advantageous and beneficial, and of itself sufficient to alarm the enemy; but they considered his own safety and that of his dominions, much more important than their own immediate convenience; because so long as the former were safe, the Florentines had nothing to fear, and
