It is again told Caesar, that the Helvetii intended to march through the country of the Sequani and the Aedui into the territories of the Santones, which are not far distant from those boundaries of the Tolosates, which [viz. Tolosa, Toulouse] is a state in the Province.
Caesari renuntiatur Helvetiis esse in animo per agrum Sequanorum et Haeduorum iter in Santonum fines facere, qui non longe a Tolosatium finibus absunt, quae civitas est in provincia.
If this took place, he saw that it would be attended with great danger to the Province to have warlike men, enemies of the Roman people, bordering upon an open and very fertile tract of country.
Id si fieret, intellegebat magno cum periculo provinciae futurum ut homines bellicosos, populi Romani inimicos, locis patentibus maximeque frumentariis finitimos haberet.
For these reasons he appointed Titus Labienus, his lieutenant, to the command of the fortification which he had made. He himself proceeds to Italy by forced marches, and there levies two legions, and leads out from winter-quarters three which were wintering around Aquileia, and with these five legions marches rapidly by the nearest route across the Alps into Further Gaul.
Ob eas causas ei munitioni quam fecerat T. Labienum legatum praeficit; ipse in Italiam magnis itineribus contendit duasque ibi legiones conscribit et tres, quae circum Aquileiam hiemabant, ex hibernis educit et, qua proximum iter in ulteriorem Galliam per Alpes erat, cum his quinque legionibus ire contendit.
Here the Centrones and the Graioceli and the Caturiges, having taken possession of the higher parts, attempt to obstruct the army in their march. After having routed these in several battles, he arrives in the territories of the Vocontii in the Further Province on the seventh day from Ocelum, which is the most remote town of the Hither Province; thence he leads his army into the country of the Allobroges, and from the Allobroges to the Segusiani. These people are the first beyond the Province on the opposite side of the Rhone.
Ibi Ceutrones et Graioceli et Caturiges locis superioribus occupatis itinere exercitum prohibere conantur. Compluribus his proeliis pulsis ab Ocelo, quod est oppidum citerioris provinciae extremum, in fines Vocontiorum ulterioris provinciae die septimo pervenit; inde in Allobrogum fines, ab Allobrogibus in Segusiavos exercitum ducit. Hi sunt extra provinciam trans Rhodanum primi.
