Although Caesar anticipated that the same thing which had happened on former occasions would then occur-that, if the enemy were routed, they would escape from danger by their speed; still, having got about thirty horse, which Commius the Atrebatian, of whom mention has been made, had brought over with him [from Gaul], he drew up the legions in order of battle before the camp. When the action commenced, the enemy were unable to sustain the attack of our men long, and turned their backs; our men pursued them as far as their speed and strength permitted, and slew a great number of them; then, having destroyed and burned every thing far and wide, they retreated to their camp.
