Boucicaut, marshal of France, was at this time governor of Genoa, and resided there. He was called upon by the duke of Milan and his brother, the count of Pavia[37], to settle a dispute which had arisen between them, respecting part of their dominions. He accepted the invitation, thinking he should do an agreeable service to the duke of Milan, and not suspecting any trick in the matter. But during his absence, the inhabitants of Genoa rebelled against his government, and sent for some of their allies and accomplices to come to them. They cruelly murdered the marshal’s lieutenant, the chevalier de Colletrie, named Chollette, a native of Auvergne, which the other Frenchmen hearing of, fled into the forts, for fear of suffering a similar fate. These were instantly besieged by the Genoese, who sent for the marquis of Montferrat[38]: he lost no time in hastening to their aid with four thousand combatants, as they had promised to pay him ten thousand florins yearly,--and they immediately elected him doge of Genoa. They also chose twelve knights, as a council to manage public affairs. A few days after, Fassincault[39], a very renowned captain in Italy, and a great friend of the marquis of Montferrat, came to Genoa with the intent of assisting the marquis; but the Genoese refused to admit him, or accept of his offers. On his return, his force, amounting to eight thousand men, took a town called Noefville; but the French retreated within the castle, which was instantly besieged. When Boucicaut heard of the rebellion of the Genoese, he set out accompanied by his men, and the duke of Milan and the count of Pavia, and arrived with speed at the castle of Gaing[40], situated between the town of Noefville[41] and Genoa, and fought with Fassincault and his forces. In this battle, eight hundred men were slain, the greater part belonging to Fassincault,--and night alone separated the combatants. Boucicaut, by the advice of Enguerrand de Bournouville and Gaiffier de la Salle, both men at arms of acknowledged prowess, advanced that night to the castle of Gaing, which he won, and amply provided it with provision and all necessary stores. Fassincault remained in the town; but seeing he could not gain the castle, he departed with his men to his own fortresses. The marshal Boucicaut carried on a severe warfare against the Genoese and those who had assisted them. He also sent messengers to inform the king of France of his situation, and to require that he would immediately send him reinforcements of men at arms.--The king and his great council, on receiving this intelligence and considering the fickleness of the Genoese, determined to proceed cautiously against them. The king sent, at his expense, the lords de Torsy, de Rambures, and de Viefville, with a certain number of men at arms, to the city of Asti, belonging to the duke of Orleans, and near to the territory of Genoa, with the hope of affording assistance to Boucicaut.
