C. Julius Caesar, Gallic War

Caesar had, as we have previously narrated, availed himself of the faithful and valuable services of this Commius, in Britain, in former years: in consideration of which merits he had exempted from taxes his [Commius's] state, and had conferred on Commius himself the country of the Morini. Yet such was the unanimity of the Gauls in asserting their freedom, and recovering their ancient renown in war, that they were influenced neither by favors, nor by the recollection of private friendship; and all earnestly directed their energies and resources to that war, and collected eight thousand cavalry, and about two hundred and forty thousand infantry. These were reviewed in the country of the Aedui, and a calculation was made of their numbers: commanders were appointed: the supreme command is intrusted to Commius the Atrebatian, Viridomarus and Eporedirix the Aeduans, and Vergasillaunus the Arvernan, the cousin-german of Vercingetorix. To them are assigned men selected from each state, by whose advice the war should be conducted. All march to Alesia , sanguine and full of confidence: nor was there a single individual who imagined that the Romans could withstand the sight of such an immense host: especially in an action carried on both in front and rear, when [on the inside] the besieged would sally from the town and attack the enemy, and on the outside so great forces of cavalry and infantry would be seen.
