Cassivelaunus, as we have stated above, all hope [rising out] of battle being laid aside, the greater part of his forces being dismissed, and about 4,000 charioteers only being left, used to observe our marches and retire a little from the road, and conceal himself in intricate and woody places, and in those neighborhoods in which he had discovered we were about to march, he used to drive the cattle and the inhabitants from the fields into the woods; and, when our cavalry, for the sake of plundering and ravaging the more freely, scattered themselves among the fields, he used to send out charioteers from the woods by all the well-known roads and paths, and, to the great danger of our horse, engaged with them; and this source of fear hindered them from straggling very extensively. The result was that Caesar did not allow excursions to be made to a great distance from the main body of the legions, and ordered that damage should be done to the enemy in ravaging their lands and kindling fires only so far as the legionary soldiers could, by their own exertion and marching, accomplish it. In the mean time the Trinobantes,[42] almost the most powerful state of those parts, from which the young man Mandubratius, embracing the protection of Caesar, had come to the continent of Gaul to [meet] him (whose father, Imanuentius, had possest the sovereignty in that state, and had been killed by Cassivelaunus; he himself had escaped death by flight) send ambassadors to Caesar, and promise that they will surrender themselves to him and perform his command: they entreat him to protect Mandubratius from the violence of Cassivelaunus, and send to their state some one to preside over it, and possess the government. Caesar demands forty hostages from them, and corn for his army, and sends Mandubratius to them. They speedily performed the things demanded, and sent hostages to the number appointed, and the corn. The Trinobantes, being protected and secured from any violence of the soldiers, the Cenimagni, the Segontiaci, the Ancalites, the Bibroci, and the Cassi, sending embassies, surrender themselves to Caesar.[43] From them he learns that the capital town of Cassivelaunus was not far from that place, and was defended by woods and morasses, and a very large number of men and of cattle had been collected in it. (Now the Britons, when they have fortified the intricate woods, in which they are wont to assemble for the purpose of avoiding the incursion of an enemy with an entrenchment and a rampart, call them a town.) Thither he proceeds with his legions; he finds the place admirably fortified by nature and art; he, however, undertakes to attack it in two directions. The enemy, having remained only a short time, did not sustain the attack of our soldiers, and hurried away on the other side of the town. A great amount of cattle was found there, and many of the enemy were taken and slain in their flight.... III OVERCOMING THE NERVII[44]
