XXXIX.--Accordingly, messengers having been forthwith despatched to the Centrones, the Grudii, the Levaci, the Pleumoxii, and the Geiduni, all of whom are under their government, they assemble as large bodies as they can, and rush unexpectedly to the winter-quarters of Cicero, the report of the death of Titurius not having as yet been conveyed to him. That also occurred to him which was the consequence of a necessary work,--that some soldiers who had gone off into the woods for the purpose of procuring timber and therewith constructing fortifications, were intercepted by the sudden arrival of [the enemy's] horse. These having been entrapped, the Eburones, the Nervii, and the Aduatuci and all their allies and dependants, begin to attack the legion: our men quickly run together to arms and mount the rampart: they sustained the attack that day with great difficulty, since the enemy placed all their hope in despatch, and felt assured that, if they obtained this victory, they would be conquerors for ever. XL.--Letters are immediately sent to Caesar by Cicero, great rewards being offered [to the messengers] if they carried them through. All the passes having been beset, those who were sent are intercepted. During the night as many as 120 towers are raised with incredible despatch out of the timber which they had collected for the purpose of fortification: the things which seemed necessary to the work are completed. The following day the enemy, having collected far greater forces, attack the camp [and] fill up the ditch. Resistance is made by our men in the same manner as the day before: this same thing is done afterwards during the remaining days. The work is carried on incessantly in the night: not even to the sick, or wounded, is opportunity given for rest: whatever things are required for resisting the assault of the next day are provided during the night: many stakes burnt at the end, and a large number of mural pikes are procured: towers are built up, battlements and parapets are formed of interwoven hurdles. Cicero himself, though he was in very weak health, did not leave himself the night-time for repose, so that he was forced to spare himself by the spontaneous movement and entreaties of the soldiers.
