§8.33.1Quo cum confestim Gaius Caninius venisset animadverteretque omnes oppidi partes praeruptissimis saxis esse munitas, quo defendente nullo tamen armatis ascendere esset difficile, magna autem impedimenta oppidanorum videret, quae si clandestina fuga subtrahere conarentur, effugere non modo equitatum, sed ne legiones quidem possent, tripertito cohortibus divisis trina excelsissimo loco castra fecit; §8.33.2a quibus paulatim, quantum copiae patiebantur, vallum in oppidi circuitum ducere instituit.
When Gaius Caninius had arrived there immediately and observed that all parts of the town were fortified by extremely steep cliffs, so that even with no one defending it, it would still be difficult for armed men to climb up, and when he saw the great baggage of the townsmen, which if they attempted to carry off by a clandestine flight, they would be unable to escape not only the cavalry but not even the legions, having divided his cohorts into three parts, he made three camps on the highest ground; from which, as far as his forces permitted, he began gradually to draw a rampart around the circuit of the town.
