Gallic War (6.31-6.34)

Whether Ambiorix did not collect his forces from cool deliberation, because he considered he ought not to engage in a battle, or [whether] he was debarred by time and prevented by the sudden arrival of our horse, when he supposed the rest of the army was closely following, is doubtful: but certainly, dispatching messengers through the country, he ordered every one to provide for himself; and a part of them fled into the forest Arduenna, a part into the extensive morasses; those who were nearest the ocean concealed themselves in the islands which the tides usually form; many, departing from their territories, committed themselves and all their possessions to perfect strangers. Cativolcus, king of one half of the Eburones, who had entered into the design together with Ambiorix, since, being now worn out by age, he was unable to endure the fatigue either of war or flight, having cursed Ambiorix with every imprecation, as the person who had been the contriver of that measure, destroyed himself with the juice of the yew-tree, of which there is a great abundance in Gaul and Germany .

The Segui and Condrusi, of the nation and number of the Germans, and who are between the Eburones and the Treviri , sent embassadors to Caesar to entreat that he would not regard them in the number of his enemies, nor consider that the cause of all the Germans on this side the Rhine was one and the same; that they had formed no plans of war, and had sent no auxiliaries to Ambiorix. Caesar, having ascertained this fact by an examination of his prisoners, commanded that if any of the Eburones in their flight had repaired to them, they should be sent back to him; he assures them that if they did that, he will not injure their territories. Then, having divided his forces into three parts, he sent the baggage of all the legions to Aduatuca. That is the name of a fort. This is nearly in the middle of the Eburones, where Titurius and Aurunculeius had been quartered for the purpose of wintering. This place he selected as well on other accounts as because the fortifications of the previous year remained, in order that he might relieve the labor of the soldiers. He left the fourteenth legion as a guard for the baggage, one of those three which he had lately raised in Italy and brought over. Over that legion and camp he places Q. Tullius Cicero and gives him 200 horse.

Having divided the army, he orders T. Labienus to proceed with three legions toward the ocean into those parts which border on the Menapii; he sends C. Trebonius with a like number of legions to lay waste that district which lies contiguous to the Aduatuci; he himself determines to go with the remaining three to the river Sambre , which flows into the Meuse , and to the most remote parts of Arduenna, whither he heard that Ambiorix had gone with a few horse. When departing, he promises that he will return before the end of the seventh day, on which day he was aware corn was due to that legion which was being left in garrison. He directs Labienus and Trebonius to return by the same day, if they can do so agreeably to the interests of the republic; so that their measures having been mutually imparted, and the plans of the enemy having been discovered, they might be able to commence a different line of operations.

There was, as we have above observed, no regular army, nor a town, nor a garrison which could defend itself by arms; but the people were scattered in all directions. Where either a hidden valley, or a woody spot, or a difficult morass furnished any hope of protection or of security to any one, there he had fixed himself. These places were known to those who dwelt in the neighborhood, and the matter demanded great attention, not so much in protecting the main body of the army (for no peril could occur to them altogether from those alarmed and scattered troops), as in preserving individual soldiers; which in some measure tended to the safety of the army. For both the desire of booty was leading many too far, and the woods with their unknown and hidden routes would not allow them to go in large bodies. If he desired the business to be completed and the race of those infamous people to be cut off, more bodies of men must be sent in several directions and the soldiers must be detached on all sides; if he were disposed to keep the companies at their standards, as the established discipline and practice of the Roman army required, the situation itself was a safeguard to the barbarians, nor was there wanting to individuals the daring to lay secret ambuscades and beset scattered soldiers. But amid difficulties of this nature as far as precautions could be taken by vigilance, such precautions were taken; so that some opportunities of injuring the enemy were neglected, though the minds of all were burning to take revenge, rather than that injury should be effected with any loss to our soldiers. Caesar dispatches messengers to the neighboring states; by the hope of booty he invites all to him, for the purpose of plundering the Eburones, in order that the life of the Gauls might be hazarded in the woods rather than the legionary soldiers; at the same time, in order that a large force being drawn around them, the race and name of that state may be annihilated for such a crime. A large number from all quarters speedily assembles.
