With the view of ascertaining their strength before testing it in a decisive action, he seized some rising ground as near to the camp of the Gauls as possible and began to construct the rampart.

When the Gauls saw the Roman standards in the distance they formed their line, prepared, with their usual impulsiveness and instinctive love of fighting, to engage at once. Observing, however, that the Romans did not come down into the plain and were trusting to the protection of their position and their rampart, they imagined that they were smitten with fear, and at the same time would be more open to attack whilst they were occupied in the work of entrenchment. So raising a wild shout they advanced to the attack.

The triarii, who formed the working party, were not interrupted, for they were screened by the hastati and principes for the explanation of these terms see Book VIII. chap. viii. who were posted in front and who began the fighting.

Their steady courage was aided by the fact that they were on higher ground, for the pila and hastae were not thrown ineffectively as often happens on level ground, but being carried forward by their weight they reached their mark.

The Gauls were borne down by the weight of the missiles which either pierced their bodies or stuck in their shields, making them extremely heavy to carry. They had almost reached the top of the hill in their charge when they halted, uncertain what to do.

The mere delay raised the courage of the Romans and depressed that of the enemy. Then the Roman line swept down upon them and forced them back; they fell over each other and caused a greater loss in this way than that inflicted by the enemy; so headlong was their flight that more were crushed to death than were slain by the sword.

But the victory was not yet decided. When the Romans reached the level ground another mass remained to be dealt with.

The number of the Gauls was great enough to prevent them from feeling the loss already sustained, and as though a new army had risen from the earth, fresh troops were brought up against their victorious enemy.

The Romans checked their onset and stood still, for not only had they, wearied as they were, to sustain a second fight, but the consul, while riding incautiously in the front, had his left shoulder almost run through by a heavy javelin and had retired.
