to watch how the balance would incline. Caesar was across the Alps. Either he would be deposed, or civil war would detain him in Italy. His legions were scattered between Trèves, Auxerre, and Sens, far from the Roman frontier. A simultaneous rising would cut them off from support, and they could be starved out or overwhelmed in detail, as Sabinus had been at Tongres and Cicero had almost been at Charleroy. Intelligence was swiftly exchanged. The chiefs of all the tribes established communications with each other. They had been deeply affected by the execution of Acco, the patriotic leader of the Carnutes. The death of Acco was an intimation that they were Roman subjects, and were to be punished as traitors if they disobeyed a Roman command. They buried their own dissensions. Except among the Aedui there was no longer a Roman faction and a patriot faction. The whole nation was inspired by a simultaneous impulse to snatch the opportunity, and unite in a single effort to assert their freedom. The understanding was complete. A day was fixed for a universal rising. The Carnutes began by a massacre which would cut off possibility of retreat, and, in revenge for Acco, slaughtered a party of Roman civilians who were engaged in business at _Gien_.[1] A system of signals had been quietly arranged. The massacre at Gien was known in a few hours in the south, and the Auvergne country, which had hitherto been entirely peaceful, rose in reply, under a young high-born chief named Vercingetorix. Gergovia, the principal town of the Arverni, was for the moment undecided.[2] The elder men there, who had known the Romans long, were against immediate action; but Vercingetorix carried the people away with him. His name had not appeared in the earlier campaigns, but his father had been a man of note beyond the boundaries of Auvergne; and he must himself have had a wide reputation among the Gauls, for everywhere, from the Seine to the Garonne, he was accepted as chief of the national confederacy. Vercingetorix had high ability and real organizing powers. He laid out a plan for the general campaign. He fixed a contingent of men and arms which each tribe was to supply, and failure brought instantaneous punishment. Mild offences were visited with the loss of eyes or ears; neglect of a more serious sort with death by fire in the wicker tower. Between enthusiasm and terror he had soon an army at his command, which he could increase indefinitely at his need. Part he left to watch the Roman province and prevent Caesar, if he should arrive, from passing through. With part he went himself to watch the Aedui, the great central race, where Roman authority had hitherto prevailed unshaken, but among whom, as he well knew, he had the mass of the people on his side. The Aedui were hesitating. They called their levies under arms, as if to oppose him, but they withdrew them again; and to waver at such a moment was to yield to the stream.
