A great battle took place before Cremona.

The dexterous management and the professional skill of the Phoenician leader failed to make up for the deficiencies of his troops; the Gauls were unable to withstand the onset of the legions, and among the numerous dead who covered the field of battle was the Carthaginian officer.

The Celts, nevertheless, continued the struggle; the same Roman army which had conquered at Cremona was next year (555), chiefly through the fault of its careless leader, almost destroyed by the Insubres; and it was not till 556 that Placentia could be partially re-established.

But the league of the cantons associated for the desperate struggle suffered from intestine discord; the Boii and Insubres quarrelled, and the Cenomani not only withdrew from the national league, but purchased their pardon from the Romans by a disgraceful betrayal of their countrymen; during a battle in which the Insubres engaged the Romans on the Mincius, the Cenomani attacked in rear, and helped to destroy, their allies and comrades in arms (557).

Thus humbled and left in the lurch, the Insubres, after the fall of Comum, likewise consented to conclude a separate peace (558).
