§8.15.1Barbari confisi loci natura, cum dimicare non recusarent, si forte Romani subire collem conarentur, paulatim copias distributas dimittere non possent, ne dispersi perturbarentur, in acie permanserunt.
The barbarians, trusting in the natural strength of the position, since they did not refuse to fight if by chance the Romans should attempt to ascend the hill, yet could not withdraw their forces in small groups for fear that they might be thrown into confusion if dispersed, remained in order of battle.
§8.15.2Quorum pertinacia cognita Caesar XX cohortibus instructis castrisque eo loco metatis muniri iubet castra.
On learning their obstinacy, Caesar, having drawn up twenty cohorts and measured out a camp in that place, ordered the camp to be fortified.
§8.15.3Absolutis operibus pro vallo legiones instructas collocat, equites frenatis equis in statione disponit.
The works being completed, he drew up the legions in front of the rampart and stationed the cavalry with their horses bridled.
§8.15.4Bellovaci, cum Romanos ad insequendum paratos viderent neque pernoctare aut diutius permanere sine periculo eodem loco possent, tale consilium sui recipiendi ceperunt.
The Bellovaci, seeing the Romans ready for pursuit and being unable either to pass the night or to remain longer in the same place without danger, formed the following plan for their retreat.
§8.15.5Fasces, ubi consederant (namque in acie sedere Gallos consuesse superioribus commentariis Caesaris declaratum est), per manus stramentorum ac virgultorum, quorum summa erat in castris copia, inter se traditos ante aciem collocarunt extremoque tempore diei signo pronuntiato uno tempore incenderunt.
They placed in front of their line the bundles of straw and brushwood, of which there was a very great abundance in their camp, handed from one to another by hand at the spots where they had been sitting (for it has been declared in the earlier commentaries of Caesar that the Gauls are accustomed to sit in line of battle), and at the end of the day, when the signal was given, they set them on fire all at once.
§8.15.6Ita continens flamma copias omnes repente a conspectu texit Romanorum.
Thus a continuous wall of flame suddenly hid all their forces from the sight of the Romans.
Quod ubi accidit, barbari vehementissimo cursu refugerunt.
When this happened, the barbarians fled at a very rapid pace.
