[-7-] After this event some other of the neighboring tribes revolted, among them the Nervii, though Quintus Cicero, a brother of Marcus Cicero and lieutenant of Caesar, was wintering in their territory. Ambiorix added them to his force and began a conflict with Cicero. The contest was close, and after capturing some prisoners alive the chieftain tried to deceive him likewise, but being unable to do so resorted to siege. Before long by means of his large force and the experience which he had gained from the campaign that he made with the Romans, together with some detailed information that he obtained from the captives, he managed to enclose him with a palisade and ditch. There were battles, as natural in such operations,--many of them,--and far larger numbers of barbarians perished, because there were more of them. They, however, by reason of their abundant army were never in sight of destruction, whereas the Romans, not being many in the first place, kept continually growing fewer and were encompassed without difficulty. [-8-] They were unable to treat their wounds with success through lack of the necessary applications, and did not have a large supply of food, because they had been besieged unexpectedly. No one came to their aid, though many were wintering at no great distance, for the barbarians guarded the roads with care and all who were sent out they caught and slaughtered before the eyes of their friends. As they were therefore in danger of being captured, a Nervian who was friendly to them as the result of kindness shown and at this time was besieged with Cicero, presented them with a slave of his to send as a messenger through the lines. Because of his dress and his native speech he would be able to associate with the enemy as one of their number, without attracting notice, and after that he could depart. [-9-] In this way Caesar learned of what was taking place (he had not yet gone to Italy but was still on the way), and, turning back, took with him the soldiers in the winter establishments through which he passed, and pressed rapidly on. Meanwhile being afraid that Cicero in despair of assistance might suffer disaster or capitulate, he sent forward a horseman. He did not trust the servant of the Nervian, in spite of having received an actual proof of his good will: he was afraid that he might pity his countrymen and work him some great evil. So he sent a horseman of the allies who knew their dialect and had dressed himself in their garb. And in order that even he might not voluntarily or involuntarily reveal the secret he gave him no verbal message and wrote to Cicero in Greek all the injunctions that he wished to give, in order that even if the letter should be captured, it might still be incomprehensible to the barbarians and afford them no information. He had also the custom as a usual thing, when he was sending a secret order to any one, to write constantly the fourth letter beyond, instead of the proper one, so that the writing might be unintelligible to most persons. The horseman reached the camp of the Romans, but not being able to come close up to it he fastened the letter to a small javelin and hurled it into the enemy's ranks, fixing it purposely in a tower.[-10-] Thus Cicero, on learning of the advent of Caesar, took courage and held out more stubbornly. The barbarians for a long time knew nothing of the assistance he was bringing; he journeyed by night, lying by day in most obscure places, so as to fall upon them as far as possible unawares. At last from the unnatural cheerfulness of the besieged they suspected it and sent out scouts. Learning from them that Caesar was at last drawing near they set out against him, thinking to attack him while off his guard. He received advance information of this movement and remained where he was that night, but just before dawn took up a strong position. There he encamped apparently with the utmost haste, for the purpose of appearing to have only a few followers, to have suffered from the journey, to fear their onset, and by this plan to draw them to the higher ground. And so it proved. Their contempt for him led them to charge up hill, and they met with such a severe defeat that they committed not another warlike act.
