and was compelled to preserve
an attitude as inactive as his opponent. It was almost a victory
for the insurgents, that Caesar's career of advance from triumph
to triumph had been suddenly checked on the Seine as on the Allier.
In fact the consequences of this check for Caesar were almost
equivalent to those of a defeat.

The Haedui Waver

The Haedui, who had hitherto continued vacillating, now made
preparations in earnest to join the patriotic party; the body
of men, whom Caesar had ordered to Gergovia, had on the march been
induced by its officers to declare for the insurgents; at the same
time they had begun in the canton itself to plunder and kill
the Romans settled there. Caesar, who had gone with two-thirds
of the blockading army to meet that corps of the Haedui which was being
brought up to Gergovia, had by his sudden appearance recalled it
to nominal obedience; but it was more than ever a hollow and fragile
relation, the continuance of which had been almost too dearly
purchased by the great peril of the two legions left behind
in front of Gergovia. For Vercingetorix, rapidly and resolutely
availing himself of Caesar's departure, had during his absence
made an attack on them, which had wellnigh ended in their
being overpowered, and the Roman camp being taken by storm.
Caesar's unrivalled celerity alone averted a second catastrophe
like that of Aduatuca. Though the Haedui made once more fair
promises, it might be foreseen that, if the blockade should still
be prolonged without result, they would openly range themselves
on the side of the insurgents and would thereby compel Caesar to raise
it; for their accession would interrupt the communication between
him and Labienus, and expose the latter especially in his isolation
to the greatest peril. Caesar was resolved not to let matters come
to this pass, but, however painful and even dangerous it was
to retire from Gergovia without having accomplished his object,
nevertheless, if it must be done, rather to set out immediately
and by marching into the canton of the Haedui to prevent
at any cost their formal desertion.

Caesar Defeated before Gergovia

Before entering however on this retreat, which was far
from agreeable to his quick and confident temperament, he made
yet a last attempt to free himself from his painful perplexity
by a brilliant success. While the bulk of the garrison of Gergovia
was occupied in intrenching the side on which the assault
was
