De Bello Gallico 2.23

2.23.1Legiōnis VIIII. et X. mīlitēs, ut in sinistrā parte aciēī cōnstiterant, pīlīs ēmissīs cursū ac lassitūdine exanimātōs vulneribusque cōnfectōs Atrebatēs (nam hīs ea pars obvēnerat) celeriter ex locō superiōre in flūmen compulērunt et trānsīre cōnantēs īnsecūtī gladiīs magnam partem eōrum impedītam interfēcērunt.

The soldiers of the ninth and tenth legions, as they had taken their stand on the left of the line, threw their javelins and quickly drove the Atrebates (for that part had fallen to them), exhausted by running and weariness and worn out by wounds, from the higher ground into the river; and following them as they tried to cross, they killed a great part of them with their swords while they were hampered.

Note. ut … cōnstiterant: here ut means 'as', with the indicative. nam hīs ea pars obvēnerat is Caesar's aside, in brackets.

2.23.2Ipsī trānsīre flūmen nōn dubitāvērunt et in locum inīquum prōgressī rūrsus resistentēs hostēs redintegrātō proeliō in fugam coniēcērunt.

They themselves did not hesitate to cross the river, and advancing onto unfavourable ground, they renewed the fight and put to flight the enemy who were resisting again.

2.23.3Item aliā in parte dīversae duae legiōnēs, XI. et VIII., prōflīgātīs Viromanduīs, quibuscum erant congressae, ex locō superiōre in ipsīs flūminis rīpīs proeliābantur.

Likewise in another place two separate legions, the eleventh and the eighth, having routed the Viromandui, with whom they had engaged, were fighting from the higher ground on the very banks of the river.

2.23.4At tōtīs ferē castrīs ā fronte et ā sinistrā parte nūdātīs, cum in dextrō cornū legiō XII. et nōn magnō ab eā intervallō VII. cōnstitisset, omnēs Nerviī cōnfertissimō agmine duce Boduognātō, quī summam imperiī tenēbat, ad eum locum contendērunt;

But with almost the whole camp left exposed at the front and on the left, while the twelfth legion had taken its stand on the right wing and the seventh not far from it, all the Nervii in a very close column, led by Boduognatus, who held the supreme command, hurried to that place;

Note. duce Boduognātō: an ablative absolute without a participle, 'with Boduognatus as leader'.

2.23.4quōrum pars ab apertō latere legiōnēs circumvenīre, pars summum castrōrum locum petere coepit.

some of them began to surround the legions on their open flank, others to make for the highest point of the camp.
