As the Ligurian operations were confined to Pisae the other consul led his army through the furthest limits of Liguria into the country of the Boii. Here totally different tactics were pursued;it was the -consul who offered battle and the enemy who declined it. As they met with no opposition the R0 dispersed on ulunderinz foravs。the Boii preferring to let 1气J砂产几毛J property be carried off with impunity rather than risk a battle in its defence. After the whole country had been laid waste with fire and sword the consul left the enemy's territory and marched in the direction of Mutina, taking as little precaution against attack as though he were in a friendly country. When the Boii found that their enemy had withdrawn from their frontiers, they followed noiselessly, looking out for a suitable place for a surprise attack. Passing by the Roman camp in the night, they seized a pass through which the Romans would have to go. This movement did not escape observation, and the consul, wh o had been in the habit of marching in the dead of the night, decided to wait for daylight so that the dangers incident to a tumultuary battle might not be augmented by darkness. Though it was quite light when he started, he sent on a squadron of cavalry to reconnoitre. On receiving their report as to the strength and position of the enemy he ordered the whole of the baggage to be collected together, and the triarii were told off to surround it with a breastwork. With the rest of his army in battle formation he advanced against the enemy. The Gauls did the same when they found that their stratagem was exposed and that they would have to fight an open and regular battle.
