Cornelius took the direct road towards the Insubrians, who were then in arms, and had been joined by the Caenomanians.
Quintus Minucius turned his route to the left side of Italy, and leading away his army to the lower sea, to Genoa, opened the campaign with an invasion of Liguria.

Two towns, Clastidium and Litubium, both belonging to the Ligurians, and two states of the same nation, Celela and Cerdicium, surrendered to him.

And now, all the states on this side of the Po, except the Boians among the Gauls and the Ilvatians among the Ligurians, were reduced to submission: no less, it is said, than fifteen towns and twenty thousand men surrendered themselves.

He then led his legions into the territory of the Boians.

The Boian army had, not very long before, crossed the Po and joined the Insubrians and Caenomanians; for, having heard that the consuls intended to act with their forces united, they wished to increase their own strength by this junction.
