The question having been debated on both sides, they proceeded to vote, as usual, and of the citizens present only ninety-eight were against the enterprise. Thus determined in favor of war, they appointed a Council of Ten for its management, and hired forces, both horse and foot. Astorre Gianni and Rinaldo degli Albizzi were appointed commissaries, and Niccolo Fortebraccio, on agreeing to give up to the Florentines the places he had taken, was engaged to conduct the enterprise as their captain. The commissaries having arrived with the army in the country of the Lucchese, divided their forces; one part of which, under Astorre, extended itself along the plain, toward Camaiore and Pietrasanta, while Rinaldo, with the other division, took the direction of the hills, presuming that when the citizens found themselves deprived of the surrounding country, they would easily submit. The proceedings of the commissaries were unfortunate, not that they failed to occupy many places, but from the complaints made against them of mismanaging the operations of the war; and Astorre Gianni had certainly given very sufficient cause for the charges against him.
There is a fertile and populous valley near Pietrasanta, called Seravezza, whose inhabitants, on learning the arrival of the commissary, presented themselves before him and begged he would receive them as faithful subjects of the Florentine republic. Astorre pretended to accept their proposal, but immediately ordered his forces to take possession of all the passes and strong positions of the valley, assembled the men in the principal church, took them all prisoners, and then caused his people to plunder and destroy the whole country, with the greatest avarice and cruelty, making no distinction in favor of consecrated places, and violating the women, both married and single. These things being known in Florence, displeased not only the magistracy, but the whole city.
