Note 510 — Chapter X · (Year of Rome 702.) (Book VII. of the “Commentaries.”) REVOLT OF GAUL—CAPTURE OF VELLAUNODUNUM, GENABUM, AND NOVIODUNUM—SIEGES OF AVARICUM AND GERGOVIA—CAMPAIGN OF LABIENUS AGAINST THE PARISII—SIEGE OF ALESIA.

It is evident that an army could not remain in the wars for eight years without receiving frequent re-enforcements in order to keep it up to its effective number. Thus, when, after the murder of Clodius, all the youth of Italy had been called to arms, Cæsar made new levies, which were used probably to swell the ranks of his legions, for no new numbers appear (De Bello Gallico, VII. 1).—In the same manner, when he arrived, in 702, in the south of Gaul, and crossed the Cévennes, he placed himself at the head of the troops which had been recruited in the Roman province and of the re-enforcements which he had brought from Italy (partem copiarum ex provincia supplementumque quod ex Italia adduxerat in Helvois, qui fines Arvernorum contingunt, convenire jubet). (De Bello Gallico, VII. 7.)—Labienus, on the other hand, during his expedition to Paris, left his recruits in dépôt at Sens (Labienus eo supplemento quod nuper ex Italia venerat relicto). (De Bello Gallico, VII. 57.)
