Indutiomarus having been slain, as we have stated, the government was conferred upon his relatives by the Treviri . They cease not to importune the neighboring Germans and to promise them money: when they could not obtain [their object] from those nearest them, they try those more remote. Having found some states willing to accede to their wishes, they enter into a compact with them by a mutual oath, and give hostages as a security for the money: they attach Ambiorix to them by an alliance and confederacy. Caesar, on being informed of their acts, since he saw that war was being prepared on all sides, that the Nervii, Aduatuci, and Menapii, with the addition of all the Germans on this side of the Rhine were under arms, that the Senones did not assemble according to his command, and were concerting measures with the Carnutes and the neighboring states, that the Germans were importuned by the Treviri in frequent embassies, thought that he ought to take measures for the war earlier [than usual].

Accordingly, while the winter was not yet ended, having concentrated the four nearest legions, he marched unexpectedly into the territories of the Nervii, and before they could either assemble or retreat, after capturing a large number of cattle and of men, and wasting their lands and giving up that booty to the soldiers, compelled them to enter into a surrender and give him hostages. That business having been speedily executed, he again led his legions back into winter-quarters. Having proclaimed a council of Gaul in the beginning of the spring, as he had been accustomed [to do], when the deputies from the rest, except the Senones , the Carnutes, and the Treviri , had come, judging this to be the commencement of war and revolt, that he might appear to consider all things of less consequence [than that war], he transfers the council to Lutetia of the Parisii . These were adjacent to the Senones , and had united their state to them during the memory of their fathers, but were thought to have no part in the present plot. Having proclaimed this from the tribunal, he advances the same day toward the Senones with his legions, and arrives among them by long marches.

Acco, who had been the author of that enterprise, on being informed of his arrival, orders the people to assemble in the towns; to them, while attempting this, and before it could be accomplished, news is brought that the Romans are close at hand: through necessity they give over their design and send embassadors to Caesar for the purpose of imploring pardon; they make advances to him through the Aedui, whose state was from ancient times under the protection of Rome . Caesar readily grants them pardon, and receives their excuse, at the request of the Aedui, because he thought that the summer season was one for an impending war, not for an investigation. Having imposed one hundred hostages, he delivers these to the Aedui to be held in charge by them. To the same place the Carnutes send embassadors and hostages, employing as their mediators the Remi, under whose protection they were: they receive the same answers. Caesar concludes the council and imposes a levy of cavalry on the states.

This part of Gaul having been tranquilized, he applies himself entirely both in mind and soul to the war with the Treviri and Ambiorix. He orders Cavarinus to march with him with the cavalry of the Senones , lest any commotion should arise either out of his hot temper, or out of the hatred of the state which he had incurred. After arranging these things, as he considered it certain that Ambiorix would not contend in battle, he watched his other plans attentively. The Menapii bordered on the territories of the Eburones, and were protected by one continued extent of morasses and woods; and they alone out of Gaul had never sent embassadors to Caesar on the subject of peace. Caesar knew that a tie of hospitality subsisted between them and Ambiorix: he also discovered that the latter had entered into an alliance with the Germans by means of the Treviri . Ho thought that these auxiliaries ought to be detached from him before he provoked him to war; lest he, despairing of safety, should either proceed to conceal himself in the territories of the Menapii, or should be driven to coalesce with the Germans beyond the Rhine . Having entered upon this resolution, he sends the baggage of the whole army to Labienus, in the territories of the Treviri and orders two legions to proceed to him: he himself proceeds against the Menapii with five lightly-equipped legions. They, having assembled no troops, as they relied on the defense of their position, retreat into the woods and morasses, and convey thither all their property.

Caesar, having divided his forces with C. Fabius, his lieutenant, and M. Crassus his questor, and having hastily constructed some bridges, enters their country in three divisions, burns their houses and villages, and gets possession of a large number of cattle and men. Constrained by these circumstances the Menapii send embassadors to him for the purpose of suing for peace. He, after receiving hostages, assures them that he will consider them in the number of his enemies if they shall receive within their territories either Ambiorix or his embassadors. Having determinately settled these things, he left among the Menapii, Commius the Atrebatian, with some cavalry as a guard; he himself proceeds toward the Treviri .
