III.-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 towards the Senones with his legions and arrives among them by long marches. IV.--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 ambassadors 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 ambassadors 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.
