C. Julius Caesar, Gallic War

The revolt of the Aedui being known, the war grows more dangerous. Embassies are sent by them in all directions: as far as they can prevail by influence, authority, or money, they strive to excite the state [to revolt]. Having got possession of the hostages whom Caesar had deposited with them, they terrify the hesitating by putting them to death. The Aedui request Vercingetorix to come to them and communicate his plans of conducting the war. On obtaining this request they insist that the chief command should be assigned to them; and when the affair became a disputed question, a council of all Gaul is summoned to Bibracte . They came together in great numbers and from every quarter to the same place. The decision is left to the votes of the mass; all to a man approve of Vercingetorix as their general. The Remi , Lingones , and Treviri were absent from this meeting; the two former because they attached themselves to the alliance of Rome ; the Treviri because they were very remote and were hard pressed by the Germans; which was also the reason of their being absent during the whole war, and their sending auxiliaries to neither party. The Aedui are highly indignant at being deprived of the chief command; they lament the change of fortune, and miss Caesar's indulgence toward them; however, after engaging in the war, they do not dare to pursue their own measures apart from the rest. Eporedirix and Viridomarus, youths of the greatest promise, submit reluctantly to Vercingetorix.
