It does not appear that the Arvernian aristocrat had absolutely declined the overtures; but when the hope of national independence was aroused, Vercingetorix was its representative and chief.

He descended with his followers from the mountain, and seized Gergovia, the capital of his nation.

Thence his messengers spread over the centre, north-west, and west of Gaul; the greater part of the peoplets and cities of those regions pronounced from the first moment for insurrection; the same sentiment was working amongst others more compromised with Rome, who waited only for a breath of success to break out.

Vercingetorix was immediately invested with the chief command, and he made use of it with all the passion engendered by patriotism and the possession of power; he regulated the movement, demanded hostages, fixed the contingents of troops, imposed taxes, inflicted summary punishment on the traitors, the dastards, and the indifferent, and subjected those who turned a deaf ear to the appeal of their common country to the same pains and the same mutilations that Caesar inflicted on those who obstinately resisted the Roman yoke.
At the news of this great movement Caesar immediately left Italy, and returned to Gaul.

He had one quality, rare even amongst the greatest men: he remained cool amidst the very hottest alarms; necessity never hurried him into precipitation, and he prepared for the struggle as if he were always sure of arriving on the spot in time to sustain it.
