he Haedui and had by this imposing
demonstration compelled the patriot party in a ferment there
to keep quiet at least for the moment, he divided his army and sent
Labienus back to Agedincum, that in combination with the troops
left there he might at the head of four legions suppress
in the first instance the movement in the territory of the Carnutes
and Senones, who on this occasion once more took the lead;
while he himself with the six remaining legions turned to the south
and prepared to carry the war into the Arvernian mountains, the proper
territory of Vercingetorix.

Labienus before Lutetia

Labienus moved from Agedincum up the left bank of the Seine with
a view to possess himself of Lutetia (Paris), the town of the Parisii
situated on an island in the Seine, and from this well-secured
position in the heart of the insurgent country to reduce it again
to subjection. But behind Melodunum (Melun), he found his route
barred by the whole army of the insurgents, which had here taken
up a position between unassailable morasses under the leadership
of the aged Camulogenus. Labienus retreated a certain distance,
crossed the Seine at Melodunum, and moved up its right bank
unhindered towards Lutetia; Camulogenus caused this town to be
burnt and the bridges leading to the left bank to be broken down,
and took up a position over against Labienus, in which the latter
could neither bring him to battle nor effect a passage
under the eyes of the hostile army.

Caesar before Gergovia
Fruitless Blockade

The Roman main army in its turn advanced along the Allier down
into the canton of the Arverni. Vercingetorix attempted to prevent
it from crossing to the left bank of the Allier, but Caesar
overreached him and after some days stood before the Arvernian
capital Gergovia.(48) Vercingetorix, however, doubtless even while
he was confronting Caesar on the Allier, had caused sufficient
stores to be collected in Gergovia and a fixed camp provided
with strong stone ramparts to be constructed for his troops in front
of the walls of the town, which was situated on the summit of a pretty
steep hill; and, as he had a sufficient start, he arrived before
Caesar at Gergovia and awaited the attack in the fortified camp
under the wall of the fortress. Caesar with his comparatively
weak army could neither regularly besiege the place nor even
sufficiently blockade it; he pitched his camp below the rising
ground occupied by Vercingetorix,
