A more formidable movement broke out among the Ædui, proportioned to the greater wealth of the state and the distance of the force which should repress it. Sacrovir with some armed cohorts had made himself master of Augustodunum, the capital of the tribe, with the noblest youth of Gaul, there devoting themselves to a liberal education, and with such hostages he proposed to unite in his cause their parents and kinsfolk. He also distributed among the youth arms which he had had secretly manufactured. There were forty thousand, one fifth armed like our legionaries; the rest had spears and knives and other weapons used in the chase. In addition were some slaves who were being trained for gladiators, clad after the national fashion in a complete covering of steel. They were called crupellarii, and though they were ill-adapted for inflicting wounds, they were impenetrable to them. This army was continually increased, not yet by any open combination of the neighbouring states, but by zealous individual enthusiasm, as well as by strife between the Roman generals, each of whom claimed the war for himself. Varro after a while, as he was infirm and aged, yielded to Silius who was in his prime.
