Insurrection of Gaul, and Campaign of 702.

VI. Not only had the murder of Clodius deeply agitated Italy, but the reverberation made itself felt beyond the Alps, and the troubles in Rome had revived in Gaul the desire to shake off the yoke of the Romans. The intestine dissensions, by spreading a belief in the debilitation of the state, awakened incessantly the hopes of its exterior enemies, and, which is sad to confess, these exterior enemies always find accomplices among traitors who are ready to betray their country.[770]

The campaign of 702 is, without dispute, the most interesting in the double point of view—political and military. To the historian, it presents the affecting scene of tribes, hitherto divided, uniting in one national thought, and arming for the purpose of re-conquering their independence. To the philosopher it presents, as a result consoling for the progress of humanity, the triumph of civilisation against the best combined and most heroic efforts of barbarism. Lastly, in the eyes of the soldier, it is a magnificent example of what may be done by energy and experience in war by a small number contending against masses who are wanting in organisation and discipline.

The events which had occurred in Rome led the Gauls to think that Cæsar would be detained in Italy, upon which a formidable insurrection is organised among them. All the different peoples act in concert, and form a coalition. The provinces in the military occupation of the legions, or held in fear by their proximity, alone remain foreign to the general agitation. The country of Orleans first gives the signal; the Roman citizens are slaughtered at Gien; Berry and Auvergne join the league; and soon, from the Seine to the Gironde, from the Cévennes to the ocean, the whole country is in arms. As a chief never fails to reveal himself when a great national movement breaks out, Vercingetorix appears, places himself at the head of a war of independence, and, for the first time, proclaims this truth, the stamp of grandeur and patriotism: “If Gaul has the sense to be united, and become one nation, it may defy the universe.” All respond to his call.

The peoples, but lately divided by rivalries, customs, and tradition, forget their reciprocal grievances, and unite under him. Foreign oppression creates nationalities much more than community of ideas and interests. Had Vercingetorix formerly, like so many others, bent his brow under the Roman domination? Dio Cassius is the only historian who says so. Be this as it may, he shows himself, as early as the year 702, the firm and intrepid adversary of the invaders. His plan is as bold as it is well combined: to create in the heart of Gaul a great centre of insurrection, protected by the mountains of the Cévennes and of Auvergne; from this natural fortress to throw his lieutenants upon the Narbonnese, whence Cæsar would be no longer able to draw either succours or provisions; to prevent even the Roman general from returning to his army; to attack separately the legions while deprived of their chief, urge into insurrection the centre of Gaul, and destroy the oppidum of the Boii, that small people, the remains of the defeat of the Helvetii, placed by Cæsar at the confluence of the Allier and the Loire as an advance sentinel.

Informed of these events, Cæsar quits Italy in haste, followed by a small number of troops raised in the Cisalpine. On his descent from the Alps, he finds himself almost alone in presence of wavering allies, and of the greatest part of Gaul in revolt, while his legions are dispersed at a distance on the Moselle, the Marne, and the Yonne. So many perils excite his ardour instead of abating it, and his resolution is soon taken.

He is going to draw his enemies, by successful and multiplied diversions, to the points where he intends to strike decisive blows; and by sending his infantry into the Vivarais, his cavalry to Vienne, and proceeding in person to Narbonne, he divides the attention of his adversaries, in order to conceal his designs.

His presence in the Roman province is equivalent to an army. He encourages the men who have remained faithful, intimidates the others; doubles, with the local resources, all the garrisons of the towns of the Province as far as Toulouse; and, after having thus raised in the south a barrier against all invasion, he returns, and arrives at the foot of the Cévennes, in the Vivarais, where he finds the troops which had been sent forward. He then crosses the mountains covered with snow, penetrates into Auvergne, and obliges Vercingetorix to abandon Berry, in order to hasten to defend his own country, which is threatened. Satisfied with this result, he starts unexpectedly, and, almost alone, hastens to Vienne. He takes the escort of cavalry which had preceded him, reaches the country of Langres, and proceeds thence to Sens, where he brings together his ten legions.

Thus, in little time, he has placed the Roman Province in security from any attack, forced Vercingetorix to fly to the defence of Auvergne, and rejoined and concentrated his army.

Although the rigour of the season adds to the difficulty of the marches and supplies of provisions (it was in the month of March), he decides upon immediately taking the field. Vercingetorix has just laid siege to Gorgobina, the oppidium of the Boii. These 20,000 Germans, so recently vanquished, preserve the sincere gratitude of a primitive people towards him who has given them lands, instead of selling them for slaves: they remain faithful to the Romans, and face the anger of Vercingetorix and the attacks of revolted Gaul. Cæsar, unwilling that a people who set the example of fidelity should become the victims of their devotedness, marches to their succour. He might go directly to Gorgobina, and cross the Loire at Nevers; but in that case, Vercingetorix, informed of his approach, would have had time to come and dispute the passage. To attempt this by force was a dangerous operation. He leaves at Sens two legions and his baggage, starts at the head of the eight others, and hastens, by the shortest way, to cross the Loire at Gien. He proceeds up the left bank of the river; while Vercingetorix, instead of waiting for him, raises the siege of Gorgobina. He proceeds to meet Cæsar, who beats him at Sancerre in a cavalry encounter, and then marches upon Bourges, without further care for an enemy incapable of arresting him in the open field. The capture of that important town must make him master of the whole country. The Gaulish general confines himself to following by short marches, and burning all the country around, in order to starve the Roman army.
