Thus the junction of the two divisions of the army was happily accomplished. The insurgents meanwhile had consulted as to the farthe conduct of the war at Bibracte (Autun) the capital of the Haeduil the soul of these consultations was again Vercingetorix, to whom the nation was enthusiastically attached after the victory of Gergovia. Particular interests were not, it is true, even now silent; the Haedui still in this death-struggle of the nation asserted their claims to the hegemony, and made a proposal in the national assembly to substitute a leader of their own for Vercingetorix. But the national representatives had not merely declined this and confirmed Vercingetorix in the supreme command, but had also adopted his plan of war without alteration. It was substantially the same as that on which he had operated at Avaricum and at Gergovia. As the base of the new position there was selected the strong city of the Mandubii, Alesia (Alise Sainte Reine near Semur in the department Cote d'Or)[49] and another entrenched camp was constructed under its walls. Immense stores were here accumulated, and the army was ordered thither from Gergovia, having its cavalry raised by resolution of the national assembly to 15,000 horse. Caesar with the whole strength of his army after it was reunited at Agedincum took the direction of Besancon, with the view of now approaching the alarmed province and protecting it from an invasion, for in fact bands of insurgents had already shown themselves in the territory of the Helvii on the south slope of the Cevennes. Alesia lay almost on his way; the cavalry of the Celts, the only arm with which Vercingetorix chose to operate, attacked him on the route, but to the surprise of all was worsted by the new German squadrons of Caesar and the Roman infantry drawn up in support of them.
Vercingetorix hastened the more to shut himself up in Alesia; and if Caesar was not disposed altogether to renounce the offensive, no course was left to him but for the third time in this campaign to proceed by way of attack with a far weaker force against an army encamped under a well-garrisoned and well-provisioned fortress and supplied with immense masses of cavalry. But, while the Celts had hitherto been opposed by only a part of the Roman legions, the whole forces of Caesar were united in the lines round Alesia, and Vercingetorix did not succeed, as he had succeeded at Avaricum and Gergovia, in placing his infantry under the protection of the walls of the fortress and keeping his external communications open for his own benefit by his cavalry, while he interrupted those of the enemy. The Celtic cavalry, already discouraged by that defeat inflicted on them by their lightly esteemed opponents, was beaten by Caesar's German horse in every encounter. The line of circumvallation of the besiegers extending about nine miles invested the whole town, including the camp attached to it.
Vercingetorix had been prepared for a struggle under the walls, but not for being besieged in Alesia; in that point of view the accumulated stores, considerable as they were, were yet far from sufficient for his army - which was said to amount to 80,000 infantry and 15,000 cavalry - and for the numerous inhabitants of the town. Vercingetorix could not but perceive that his plan of warfare had on this occasion turned to his own destruction, and that he was lost unless the whole nation hastened up to the rescue of its blockaded general. The existing provisions were still, when the Roman circumvallation was closed, sufficient for a month and perhaps something more; at the last moment, when there was still free passage at least for horsemen, Vercingetorix dismissed his whole cavalry, and sent at the same time to the heads of the nation instructions to call out all their forces and lead them to the relief of Alesia. He himself, resolved to bear in person the responsibility for the plan of war which he had projected and which had miscarried, remained in the fortress, to share in good or evil the fate of his followers. But Caesar made up his mind at once to besiege and to be besieged. He prepared his line of circumvallation for defence also on its outer side, and furnished himself with provisions for a longer period. The days passed; they had no longer a boll of grain in the fortress, and they were obliged to drive out the unhappy inhabitants of the town to perish miserably between the entrenchments of the Celts and of the Romans, pitilessly rejected by both.
At the last hour there appeared behind Caesar's lines the interminable array of the Celto-Belgic relieving array, said to amount to 250,000 infantry and 8000 cavalry, from the Channel to the Cevennes the insurgent cantons had strained every nerve to rescue the flower of their patriots and the general of their choice - the Bellovaci alone had answered that they were doubtless disposed to fight against the Romans, but not beyond their own bounds. The first assault, which the besieged of Alesia and the relieving troops without made on the Roman double line, was repulsed; but, when after a day's rest it was repeated, the Celts succeeded - at a spot where the line of circumvallation ran over the slope of a hill and could be assailed from the height above - in filling up the trenches and hurling the defenders down from the rampart. Then Labienus, sent thither by Caesar, collected the nearest cohorts and threw himself with four legions on the foe. Under the eyes of the general, who himself appeared at the most dangerous moment, the assailants were driven back in a desperate hand-to-hand conflict, and the squadrons of cavalry that came with Caesar taking the fugitives in rear completed the defeat.
It was more than a great victory; the fate of Alesia, and indeed of the Celtic nation, was thereby irrevocably decided. The Celtic army, utterly disheartened, dispersed at once from the battle-field and went home. Vercingetorix might perhaps have even now taken to flight, or at least have saved himself by the last means open to a free man; he did not do so, but declared in a council of war that, since he had not succeeded in breaking off the alien yoke, he was ready to give himself up as a victim and to avert as far as possible destruction from the nation by bringing it on his own head. This was done. The Celtic officers delivered their general - the solemn choice of the whole nation - over to the energy of their country for such punishment as might be thought fit. Mounted on his steed and in full armour the king of the Arverni appeared before the Roman proconsul and rode round his tribunal; then he surrendered his horse and arms, and sat down in silence on the steps at Caesar's feet (702).
Five years afterwards he was led in triumph through the streets of the Italian capital, and, while his conqueror was offering solemn thanks to the gods on the summit of the Capitol, Vercingetorix was beheaded at its foot as guilty of high treason against the Roman nation. As after a day of gloom the sun may perhaps break through the clouds at its setting, so destiny may bestow on nations in their decline yet a last great man. Thus Hannibal stands at the close of the Phoenician history, and Vercingetorix at the close of the Celtic. They were not able to save the nations to which they belonged from a foreign yoke, but they spared them the last remaining disgrace - an inglorious fall. Vercingetorix, just like the Carthaginian, was obliged to contend not merely against the public foe, but also and above all against that anti-national opposition of wounded egotists and startled cowards, which regularly accompanies a degenerate civilization; for him too a place in history is secured, not by his battles and sieges, but by the fact that he was able to furnish in his own person a centre and rallying-point to a nation distracted and ruined by the rivalry of individual interests. And yet there can hardly be a more marked contrast than between the sober townsman of the Phoenician mercantile city, whose plans were directed towards one great object with unchanging energy throughout fifty years, and the bold prince of the Celtic land, whose mighty deeds and high-minded self-sacrifice fall within the compass of one brief summer. The whole ancient world presents no more genuine knight, whether as regards his essential character or his outward appearance.
49. The question so much discussed of late, whether Alesia is not rather to be identified with Alaise (25 kilometres to the south of Besancon, dep. Doubs), has been rightly answered in the negative by all judicious inquirers.
