The expected capture of Gergovia had been converted into a defeat, and the considerable loss in killed and wounded-- there were counted 700 soldiers that had fallen, including 46 centurions--was the least part of the misfortune suffered.
Renewed Insurrection Rising of the Haedui Rising of the Belgae The imposing position of Caesar in Gaul depended essentially on the halo of victory that surrounded him; and this began to grow pale.
The conflicts around Avaricum, Caesar's vain attempts to compel the enemy to fight, the resolute defence of the city and its almost accidental capture by storm bore a stamp different from that of the earlier Celtic wars, and had strengthened rather than impaired the confidence of the Celts in themselves and their leader.
Moreover, the new system of warfare--the making head against the enemy in intrenched camps under the protection of fortresses--had completely approved itself at Lutetia as well as at Gergovia.

Lastly, this defeat, the first which Caesar in person had suffered from the Celts crowned their success, and it accordingly gave as it were the signal for a second outbreak of the insurrection.
The Haedui now broke formally with Caesar and entered into union with Vercingetorix.

Their contingent, which was still with Caesar's army, not only deserted from it, but also took occasion to carry off the depots of the army of Caesar at Noviodunum on the Loire, whereby the chests and magazines, a number of remount-horses, and all the hostages furnished to Caesar, fell into the hands of the insurgents.

It was of at least equal importance, that on this news the Belgae, who had hitherto kept aloof from the whole movement, began to bestir themselves.

The powerful canton of the Bellovaci rose with the view of attacking in the rear the corps of Labienus, while it confronted at Lutetia the levy of the surrounding cantons of central Gaul.
Everywhere else too men were taking to arms; the strength of patriotic enthusiasm carried along with it even the most decided and most favoured partisans of Rome, such as Commius king of the Atrebates, who on account of his faithful services had received from the Romans important privileges for his community and the hegemony over the Morini.
