Caesar, on observing these movements, sends Labienus with six cohorts to relieve his distressed soldiers:
His rebus cognitis Caesar Labienum cum cohortibus sex subsidio laborantibus mittit:
he orders him, if he should be unable to withstand them, to draw off the cohorts and make a sally; but not to do this except through necessity.
imperat, si sustinere non posset, deductis cohortibus eruptione pugnaret; id nisi necessario ne faciat.
He himself goes to the rest, and exhorts them not to succumb to the toil; he shows them that the fruits of all former engagements depend on that day and hour.
Ipse adit reliquos, cohortatur ne labori succumbant; omnium superiorum dimicationum fructum in eo die atque hora docet consistere.
The Gauls within, despairing of forcing the fortifications in the plains on account of the greatness of the works, attempt the places precipitous in ascent: hither they bring the engines which they had prepared;
Interiores desperatis campestribus locis propter magnitudinem munitionum loca praerupta ex ascensu temptant: huc ea quae paraverant conferunt.
by the immense number of their missiles they dislodge the defenders from the turrets: they fill the ditches with clay and hurdles, then clear the way; they tear down the rampart and breast-work with hooks.
Multitudine telorum ex turribus propugnantes deturbant, aggere et cratibus fossas explent, falcibus vallum ac loricam rescindunt.
