The remains of the old Gaulish bands had united on the left bank of the Loire, the constant refuge of the last defenders of their country, and were still displaying an energy sufficient to give uneasiness to the conquerors. They joined Dumnacus, the chief of the Angevins, who was besieging, in Poitiers, Duratius, a Gaulish chief faithful to the Romans. Cæsar’s lieutenants, Caninius Rebilus and C. Fabius, obliged Dumnacus to raise the siege, and defeated his army. During this time, Drappes of Sens and Lucterius of Cahors, who had escaped from the last battle, attempted to invade the Roman province; but, pursued by Rebilus, they threw themselves into the fortress of Uxellodunum (_le Puy d’Issolu_), where the last focus of the insurrection was destined to be extinguished. After a battle outside the fortress, in which the Romans were victorious, Drappes fell into their power; Rebilus and Fabius continued the siege. But the courage of the besieged rendered useless the efforts of the besiegers. At this conjuncture Cæsar arrived there. Seeing that the place, being obstinately defended and abundantly provisioned, could not be reduced either by force or by famine, he conceived the idea of depriving the besieged of water. For this purpose, a subterranean gallery was carried to the veins of the spring which, alone, supplied their wants. It became instantly dry. The Gauls, taking this circumstance for a prodigy, believed they saw in it a manifestation of the will of the gods, and surrendered. Cæsar inflicted on the heroic defenders of Uxellodunum an atrocious punishment: he caused their hands to be cut off; an unpardonable act of cruelty, even although it might have appeared necessary. These events accomplished, he visited Aquitaine for the first time, with two legions, and saw his authority accepted everywhere. He subsequently proceeded to Narbonne, and from thence to Arras, where he established his head-quarters for the winter. Labienus, on his side, had obtained the complete submission of the country of Trèves. [Sidenote: Cæsar’s Policy in Gaul and at Rome.] II. After eight years of sanguinary struggles, Gaul was subdued, and thenceforward, far from meeting enemies in it, Cæsar was destined to find only auxiliaries. His policy had contributed as much as his arms to this result. Instead of seeking to reduce Gaul into a Roman province, the great captain had applied himself to founding the supremacy of the Republic on powerful alliances, making the conquered countries subject to the states of which he was sure, and leaving to each people its chiefs and its institutions, and to Gaul entire its general assemblies.
