3.21.1Pugnātum est diū atque ācriter, cum Sotiātēs superiōribus victōriīs frētī in suā virtūte tōtīus Aquītāniae salūtem positam putārent, nostrī autem quid sine imperātōre et sine reliquīs legiōnibus adulēscentulō duce efficere possent perspicī cuperent;The fighting was long and fierce, since the Sotiates, relying on earlier victories, thought that the safety of all Aquitania rested on their courage, while our men were eager to show what they could do without their commander-in-chief and the other legions, with a very young man as leader;Note. superiōribus victōriīs frētī: frētus takes the ablative, 'relying on'. adulēscentulō duce: an ablative absolute without a participle, 'with a very young man as leader'. 3.21.1tandem cōnfectī vulneribus hostēs terga vertērunt.at last the enemy, worn out by wounds, turned and fled. 3.21.2Quōrum magnō numerō interfectō Crassus ex itinere oppidum Sotiātium oppugnāre coepit.After killing a great number of them, Crassus began straight from the march to attack the town of the Sotiates. 3.21.2Quibus fortiter resistentibus vīneās turrēsque ēgit.When they resisted bravely, he brought up mantlets and towers. 3.21.3Illī aliās ēruptiōne temptātā, aliās cunīculīs ad aggerem vīneāsque āctīs (cuius reī sunt longē perītissimī Aquītānī, proptereā quod multīs locīs apud eōs aerāriae sectūraeque sunt), ubi dīligentiā nostrōrum nihil hīs rēbus prōficī posse intellēxērunt, lēgātōs ad Crassum mittunt sēque in dēditiōnem ut recipiat petunt.They tried now a sally, now tunnels driven toward the siege ramp and mantlets (the Aquitani are by far the most skilled at this, because in many places among them there are copper mines and quarries); when they realised that because of our men's care nothing could be achieved by these means, they send envoys to Crassus and ask him to accept their surrender.Note. aliās … aliās: 'at one time … at another'. cuius reī: 'in which thing', genitive with perītissimī.
