The Roman central division forced the Viromandui down the declivity.

But the right wing, where the general himself was present, was outflanked by the far more numerous Nervii the more easily, as the central division carried away by its own success had evacuated the ground alongside of it, and even the half-ready camp was occupied by the Nervii; the two legions, each separately rolled together into a dense mass and assailed in front and on both flanks, deprived of most of their officers and their best soldiers, appeared on the point of being broken and cut to pieces.

The Roman camp-followers and the allied troops were already fleeing in all directions; of the Celtic cavalry whole divisions, like the contingent of the Treveri, galloped off at full speed, that from the battle-field itself they might announce at home the welcome news of the defeat which had been sustained.

Everything was at stake.

The general himself seized his shield and fought among the foremost; his example, his call even now inspiring enthusiasm, induced the wavering ranks to rally.
