Gallic War (3.22-3.26)

And while the attention of our men is engaged in that matter, in another part Adcantuannus, who held the chief command, with 600 devoted followers whom they call soldurii (the conditions of whose association are these,-that they enjoy all the conveniences of life with those to whose friendship they have devoted themselves: if any thing calamitous happen to them, either they endure the same destiny together with them, or commit suicide: nor hitherto, in the, memory of men, has there been found any one who, upon his being slain to whose friendship he had devoted himself, refused to die); Adcantuannus, [Isay] endeavoring to make a sally with these, when our soldiers had rushed together to arms, upon a shout being raised at that part of the, fortification, and a fierce battle had been fought there, was driven back into the town, yet he obtained from Crassus [the indulgence] that he should enjoy the same terms of surrender [as the other inhabitants].

Crassus, having received their arms and hostages, marched into the territories of the Vocates and the Tarusates. But then, the barbarians being alarmed, because they had heard that a town fortified by the nature of the place and by art, had been taken by us in a few days after our arrival there, began to send embassadors into all quarters, to combine, to give hostages one to another, to raise troops. Embassadors also are sent to those states of Hither Spain which are nearest to Aquitania , and auxiliaries and leaders are summoned from them; on whose arrival they proceed to carry on the war with great confidence, and with a great host of men. They who had been with Q. Sertorius the whole period [of his war in Spain] and were supposed to have very great skill in military matters, are chosen leaders. These, adopting the practice of the Roman people, begin to select [advantageous] places, to fortify their camp, to cut off our men from provisions, which, when Crassus observes, [and likewise] that his forces, on account of their small number could not safely be separated; that the enemy both made excursions and beset the passes, and [yet] left sufficient guard for their camp; that on that account, corn and provision could not very conveniently be brought up to him, and that the number of the enemy was daily increased, he thought that he ought not to delay in giving battle. This matter being brought to a council, when he discovered that all thought the same thing, he appointed the next day for the fight.

Having drawn out all his forces at the break of day, and marshaled them in a double line, he posted the auxiliaries in the center, and waited to see what measures the enemy would take. They, although on account of their great number and their ancient renown in war, and the small number of our men, they supposed they might safely fight, nevertheless considered it safer to gain the victory without any wound, by besetting the passes [and] cutting off the provisions: and if the Romans, on account of the want of corn, should begin to retreat, they intended to attack them while encumbered in their march and depressed in spirit [as being assailed while] under baggage. This measure being approved of by the leaders and the forces of the Romans drawn out, the enemy [still] kept themselves in their camp. Crassus having remarked this circumstance, since the enemy, intimidated by their own delay, and by the reputation [i.e. for cowardice arising thence] had rendered our soldiers more eager for fighting, and the remarks of all were heard [declaring] that no longer ought delay to be made in going to the camp, after encouraging his men, he marches to the camp of the enemy, to the great gratification of his own troops.)

There, while some were filling up the ditch, and others, by throwing a large number of darts, were driving the defenders from the rampart and fortifications, and the auxiliaries, on whom Crassus did not much rely in the battle, by supplying stones and weapons [to the soldiers], and by conveying turf to the mound, presented the appearance and character of men engaged in fighting; while also the enemy were fighting resolutely and boldly, and their weapons, discharged from their higher position, fell with great effect; the horse, having gone round the camp of the enemy, reported to Crassus that the camp was not fortified with equal care on the side of the Decuman gate, and had an easy approach.

Crassus, having exhorted the commanders of the horse to animate their men by great rewards and promises, points out to them what he wished to have done. They, as they had been commanded, having brought out the four cohorts, which, as they had been left as a guard for the camp, were not fatigued by exertion, and having led them round by a some what longer way, lest they could be seen from the camp of the enemy, when the eyes and minds of all were intent upon the battle, quickly arrived at those fortifications which we have spoken of, and, having demolished these, stood in the camp of the enemy before they were seen by them, or it was known what was going on. And then, a shout being heard in that quarter, our men, their strength having been recruited, (which usually occurs on the hope of victory), began to fight more vigorously. The enemy surrounded on all sides, [and] all their affairs being despaired of, made great attempts to cast themselves down over the ramparts and to seek safety in flight. These the cavalry pursued over the very open plains, and after leaving scarcely a fourth part out of the number of 50,000, which it was certain had assembled out of Aquitania and from the Cantabri, returned late at night to the camp.
