and villages, destroy the magazines, and endanger the supplies and the communications of the enemy, without his being able seriously to hinder it.  Vercingetorix accordingly directed all his efforts to the increase of his cavalry, and of the infantry-archers who were according to the mode of fighting of that time regularly associated with it.  He did not send the immense and self-obstructing masses of the militia of the line to their homes, but he did not allow them to face the enemy, and attempted to impart to them gradually some capacity of intrenching, marching, and manoeuvring, and some perception that the soldier is not destined merely for hand-to-hand combat.  Learning from the enemy, he adopted in particular the Roman system of encampment, on which depended the whole secret of the tactical superiority of the Romans; for in consequence of it every Roman corps combined all the advantages of the garrison of a fortress with all the advantages of an offensive army.(47) It is true that a system completely adapted to Britain which had few towns and to its rude, resolute, and on the whole united inhabitants was not absolutely transferable to the rich regions on the Loire and their indolent inhabitants on the eve of utter political dissolution.  Vercingetorix at least accomplished this much, that they did not attempt as hitherto to hold every town with the result of holding none; they agreed to destroy the townships not capable of defence before attack reached them, but to defend with all their might the strong fortresses.  At the same time the Arvernian king did what he could to bind to the cause of their country the cowardly and backward by stern severity, the hesitating by entreaties and representations, the covetous by gold, the decided opponents by force, and to compel or allure the rabble high or low to some manifestation of patriotism.

Beginning of the Struggle

Even before the winter was at an end, he threw himself on the Boii settled by Caesar in the territory of the Haedui, with the view of annihilating these, almost the sole trustworthy allies of Rome, before Caesar came up.  The news of this attack induced Caesar, leaving behind the baggage and two legions in the winter quarters of Agedincum (Sens), to march immediately and earlier than he would doubtless otherwise have done, against the insurgents.  He remedied the sorely-felt want of cavalry and light infantry in some measure by gradually bringing up German mercenaries, who instead of using their own small and weak ponies were furnished with Italian and Spanish horses partly bought, partly procured by requisition of the officers.  Caesar, after having by the way caused Cenabum, the capital of the Carnutes, which had given the signal for the revolt, to be pillaged and laid in ashes, moved over the Loire into the country of the Bituriges.  He thereby induced Vercingetorix to abandon the siege of the town of the Boii, and to resort likewise to the Bituriges.  Here the new mode of warfare was first to be tried.  By order of Vercingetorix more than twenty townships of the Bituriges perished in the flames on one day; the general decreed a similar self-devastation as to the neighbour cantons, so far as they could be reached by the Roman foraging parties.
