C. Julius Caesar, Gallic War

1. Caesar, expecting for many reasons a greater commotion in Gaul, resolves to hold a levy by the means of M. Silanus C. Antistius Reginus, and T. Sextius, his lieutenants: at the same time he requested Cn. Pompey, the proconsul, that since he was remaining near the city invested with military command for the interests of the commonwealth, he would command those men whom when consul [55 B.C.] he had levied by the military oath in Cisalpine Gaul, to join their respective corps, and to proceed to him; thinking it of great importance, as far as regarded the opinion which the Gauls would entertain for the future, that that the resources of Italy should appear so great that if any loss should be sustained in war, not only could it be repaired in a short time, but likewise be further supplied by still larger forces. And when Pompey had granted this to the interests of the commonwealth and the claims of friendship, Caesar having quickly completed the levy by means of his lieutenants, after three regiments had been both formed and brought to him before the winter [had] expired, and the number of those cohorts which he had lost under Q. Titurius had been doubled, taught the Gauls, both by his dispatch and by his forces what the discipline and the power of the Roman people could accomplish.
