The example of Dumnorix was followed, before long, by almost the whole of Roman Gaul; the principal cities being quite unable to resist the temptation offered by the long absence of their enemy at the capital. Cæsar, writing from Rome, protested vigorously against the ingratitude of the Aedui. He reminded them of their grievous plight before his legions freed them; of their decimated armies, of their ravaged land, of the heavy tributes, the noble hostages wrung from them. But he spoke in deaf ears. The Aedui had definitely linked their destiny with that of their nation. Only the final arbitrament of force could be appealed to. They summoned to a council of war, Vercingetorix, the ablest general of his day, chief of their hereditary enemies, the Arverni; but, accustomed for long to regard themselves as the dominant tribe of the Gauls, they offered him only a subordinate command. His refusal of any command, other than the highest, was followed by an assembly general of the Gallic tribes at Bibracte, when, on the matter being put to the vote, the great meeting, with one voice, proclaimed Vercingetorix their leader.[15] The story of his last desperate struggle against the Romans at Alesia, and of his defeat and death, do not properly belong to the history of Autun, nor to that of Bibracte. Gaul had become a province of the great Roman Empire. A higher civilisation, already familiar to the conquered tribes, is to impose its dominion, its architecture, its art, upon the conquered land. Bibracte, the oppidum on the wooded hills, will echo no more to the shouts of Gauls acclaiming their general or their victory. Deserted, probably in the first years of the Christian era, silence reigns henceforth over the hills; silence broken only by the patter of rain drops, by the moan of the wind, or the weird howl of the wolf, roaming, at midnight, among the ruins of the abandoned city.
