l 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. The threads of the insurrection
ramified even into the old Roman province: they cherished the hope,
perhaps not without ground, of inducing the Allobroges themselves
to take arms against the Romans. With the single exception
of the Remi and of the districts--dependent immediately on the Remi--
of the Suessiones, Leuci, and Lingones, whose peculiar isolation
was not affected even amidst this general enthusiasm, the whole Celtic
nation from the Pyrenees to the Rhine was now in reality,
for the first and for the last time, in arms for its freedom
and nationality; whereas, singularly enough, the whole German
communities, who in the former struggles had held the foremost
rank, kept aloof. In fact, the Treveri, and as it would seem
the Menapii also, were prevented by their feuds with the Germans
from taking an active part in the national war.

Caesar Unites with Labienus

It was a grave and decisive moment, when after the retreat
from Gergovia and the loss of Noviodunum a council of war was held
in Caesar's headquarters regarding the measures now to be adopted.
Various voices expressed themselves in favour of a retreat over
the Cevennes into the old Roman province, which now lay open
on all sides to the insurrection and certainly was in urgent need
of the legions that had been sent fro
