At daybreak, the Roman troops issued from the camp and formed in two lines, with the auxiliaries in the centre; in this position they awaited the enemy. The latter, trusting in their numbers, full of recollections of their ancient glory, imagined that they could easily overpower the weak Roman army. Still they thought it more prudent to obtain the victory without a blow, persuaded that by intercepting his provisions they would force Crassus to a retreat, and that they should then attack with advantage in the confusion of his march. They therefore remained shut up in their camp, and let the Romans range their troops and offer battle. But this deliberate temporising, which had all the appearance of fear, kindled, on the contrary, that of the Romans: they demanded with loud cries to march against the enemy without delay. Crassus yields to their impatience, and leads them forward. Some fill the fosse, others drive away with a shower of missiles the barbarians who stand on the rampart. The auxiliaries, on whom Crassus placed little reliance for action, render, nevertheless, important services: they pass the stones and missiles, or carry heaps of turf to fill up the fosse. Meanwhile the enemy was offering an obstinate resistance, when some of the cavalry brought information to Crassus that, on the side of the Decuman gate, the camp was not so well fortified, and that the access was more easy.[291] He then directs the prefects of the cavalry to excite the ardour of the soldiers with the hope of recompenses; orders them to take the cohorts who, left to guard the camp, had not yet been engaged in the battle, and to lead them by a long circuit to the place reported to be least defended. While the barbarians are solely occupied with the principal attack, these cohorts rush into the camp; on hearing the clamour which arises from this attack, the assailants, led by Crassus, redouble their efforts. The barbarians, surrounded on all sides, lose courage, rush out of the retrenchments, and seek their safety in flight. The cavalry overtook them in the open plain, and of 50,000 Aquitanians or Cantabrians, hardly one quarter escaped, who only reached the camp very late in the night. At the news of this victory, the greater part of the peoples of Aquitaine[292] submitted to Crassus, and sent spontaneously him hostages; some, nevertheless, who were more distant, and reckoned on the advanced period of the season, refused to make their submission.[293] [Sidenote: March against the Morini and the Menapii.]
