It was self-evident that the task would now be resumed at the point where it had been broken off, and the Celts were well aware of this. In the very year of the conclusion of peace with Carthage (553) hostilities had recommenced in the territory of the Boii, who were the most immediately exposed to danger; and a first success obtained by them over the hastily-assembled Roman levy, coupled with the persuasions of a Carthaginian officer, Hamilcar, who had been left behind from the expedition of Mago in northern Italy, produced in the following year (554) a general insurrection spreading beyond the two tribes immediately threatened, the Boii and Insubres. The Ligurians were driven to arms by the nearer approach of the danger, and even the youth of the Cenomani on this occasion listened less to the voice of their cautious chiefs than to the urgent appeal of their kinsmen who were in peril. Of "the two barriers against the raids of the Gauls," Placentia and Cremona, the former was sacked--not more than 2000 of the inhabitants of Placentia saved their lives--and the second was invested.

But the league of the cantons associated for the desperate struggle suffered
