In proportion as the attack became daily more formidable and violent, and particularly because, as a great number of the soldiers were exhausted with wounds, the matter had come to a small number of defenders, more frequent letters and messengers were sent to Caesar; a part of which messengers were taken and tortured to death in the sight of our soldiers. There was within our camp a certain Nervian, by name Vertico, born in a distinguished position, who in the beginning of the blockade had deserted to Cicero, and had exhibited his fidelity to him. He persuades his slave, by the hope of freedom, and by great rewards, to convey a letter to Caesar. This he carries out bound about his javelin, and mixing among the Gauls without any suspicion by being a Gaul, he reaches Caesar. From him they received information of the imminent danger of Cicero and the legion.
Caesar having received the letter about the eleventh hour of the day, immediately sends a messenger to the Bellovaci, to M. Crassus, questor there, whose winter-quarters were twenty-five miles distant from him. He orders the legion to set forward in the middle of the night and come to him with despatch. Crassus set out with the messenger. He sends anther to C. Fabius, the lieutenant, ordering him to lead forth his legion into the territories of the Atrebates, to which he knew his march must be made. He writes to Labienus to come with his legion to the frontiers of the Nervii, if he could do so to the advantage of the commonwealth: he does not consider that the remaining portion of the army, because it was somewhat farther distant, should be waited for; but assembles about 400 horse from the nearest winter-quarters.
Having been apprised of the arrival of Crassus by the scouts at about the third hour, he advances twenty miles that day. He appoints Crassus over Samarobriva and assigns him a legion, because he was leaving there the baggage of the army, the hostages of the states, the public documents, and all the corn, which he had conveyed thither for passing the winter. Fabius, without delaying a moment, meets him on the march with his legion, as he had been commanded. Labienus, having learnt the death of Sabinus and the destruction of the cohorts, as all the forces of the Treviri had come against him, beginning to fear lest, if he made a departure from his winter-quarters, resembling a flight, he should not be able to support the attack of the enemy, particularly since he knew them to be elated by their recent victory, sends back a letter to Caesar, informing him with what great hazard he would lead out his legion from winter-quarters; he relates at large the affair which had taken place among the Eburones; he informs him that all the infantry and cavalry of the Treviri had encamped at a distance of only three miles from his own camp.
Caesar, approving of his motives, although he was disappointed in his expectation of three legions, and reduced to two, yet placed his only hopes of the common safety in despatch. He goes into the territories of the Nervii by long marches. There he learns from some prisoners what things are going on in the camp of Cicero, and in how great jeopardy the affair is. Then with great rewards he induces a certain man of the Gallic horse to convey a letter to Cicero. This he sends written in Greek characters, lest the letter being intercepted, our measures should be discovered by the enemy. He directs him, if he should be unable to enter, to throw his spear with the letter fastened to the thong, inside the fortifications of the camp. He writes in the letter, that he having set out with his legions, will quickly be there: he entreats him to maintain his ancient valour. The Gaul apprehending danger, throws his spear as he had been directed. It by chance stuck in a tower, and,
