but sent also a corps over the snow-covered Cevennes into the Arvernian territory; but he could not remain here, where the accession of the Haedui to the Gallic alliance might any moment cut him off from his army encamped about Sens and Langres. With all secrecy he went to Vienna, and thence, attended by only a few horsemen, through the territory of the Haedui to his troops. The hopes, which had induced the conspirators to declare themselves, vanished; peace continued in Italy, and Caesar stood once more at the head of his army.

The Gallic Plan of War

But what were they to do? It was folly under such circumstances to let the matter come to the decision of arms; for these had already decidedly irrevocably. They might as well attempt to shake the Alps by throwing stones at them as to shake the legions by means of the Celtic bands, whether these might be congregated in huge masses or sacrificed in detail canton after canton. Vercingetorix despaired of defeating the Romans. He adopted a system of warfare similar to that by which Cassivellaunus had saved the insular Celts. The Roman infantry was not to be vanquished; but Caesar's cavalry consisted almost exclusively of the contingent of the Celtic nobility, and was practically dissolved by the general revolt. It was possible for the insurrection, which was in fact essentially composed of the Celtic nobility, to develop such a superiority in this arm, that it could lay waste the land far and wide, burn down towns 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.

Caesar before Arvaricum

According to his intention, Avaricum (Bourges), the rich and strong capital of the Bituriges, was to meet the same fate; but the majority of the war-council yielded to the suppliant entreaties of the Biturigian authorities, and resolved rather to defend that city with all their energy. Thus the war was concentrated in the first instance around Avaricum, Vercingetorix placed his infantry amidst the morasses adjoining the town in a position so unapproachable, that even without being covered by the cavalry they needed not to fear the attack of the legions. The Celtic cavalry covered all the roads and obstructed the communication. The town was strongly garrisoned, and the connection between it and the army before the walls was kept open. Caesar's position was very awkward. The attempt to induce the Celtic infantry to fight was unsuccessful; it stirred not from its unassailable lines. Bravely as his soldiers in front of the town trenched and fought, the besieged vied with them in ingenuity and courage, and they had almost succeeded in setting fire to the siege apparatus of their opponents. The task withal of supplying an army of nearly 60,000 men with provisions in a country devastated far and wide and scoured by far superior bodies of cavalry became daily more difficult. The slender stores of the Boii were soon used up; the supply promised by the Haedui failed to appear; the corn was already consumed, and the soldier was placed exclusively on flesh-rations. But the moment was approaching when the town, with whatever contempt of death the garrison fought, could be held no longer. Still it was not impossible to withdraw the troops secretly by night and destroy the town, before the enemy occupied it. Vercingetorix made arrangements for this purpose, but the cry of distress raised at the moment of evacuation by the women and children left behind attracted the attention of the Romans; the departure miscarried.

Avaricum Conquered
Caesar Divides His Army

On the following gloomy and rainy day the Romans scaled the walls, and, exasperated by the obstinate defence, spared neither age nor sex in the conquered town. The ample stores, which the Celts had accumulated in it, were welcome to the starved soldiers of Caesar. With the capture of Avaricum (spring of 702), a first success had been achieved over the insurrection, and according to former experience Caesar might well expect that it would now dissolve, and that it would only be requisite to deal with the cantons individually. After he had therefore shown himself with his whole army in the canton of the 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, 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 expected, the Roman general watched his opportunity to surprise another access less conveniently situated but at the moment left bare. In reality the Roman storming columns scaled the camp-wall, and occupied the nearest quarters of the camp; but the whole garrison was already alarmed, and owing to the small distances Caesar found it not advisable to risk the second assault on the city-wall. He gave the signal for retreat; but the foremost legions, carried away by the impetuosity of victory, heard not or did not wish to hear, and pushed forward without
