IV. The most warlike tribes had been vanquished, and none of them dreamt of further revolt. Nevertheless, many inhabitants of the newly-conquered countries abandoned the towns and the fields in order to withdraw themselves from the Roman dominion. Cæsar, in order to put a stop to this emigration, distributed his army into different countries. He ordered the quæstor Mark Antony to come to him, with the 12th legion, and sent the lieutenant Fabius with twenty-five cohorts into an opposite part of Gaul (to the country situated between the Creuse and the Vienne), where it was said that several peoples were in arms, and where the lieutenant Caninius Rebilus, who commanded with two legions, appeared not to be sufficiently strong;[548] lastly, he ordered T. Labienus to join him in person, and to send the 15th legion,[549] which he had under his command, into Cisalpine Gaul, to protect the colonies of Roman citizens there against the sudden inroads of the barbarians, who, the summer before, had attacked the Tergestini (the inhabitants of Trieste). As for Cæsar, he proceeded with four legions to the territory of the Eburones, to lay it waste; as he could not secure Ambiorix, who was still wandering at large, he thought it advisable to destroy everything by fire and sword, persuaded that this chief would never dare to return to a country on which he had brought such a terrible calamity: the legions and the auxiliaries were charged with this execution. Then, he sent Labienus with two legions to the country of the Treviri, who, always at war with the Germans, were only kept in obedience by the presence of a Roman army.[550] [Sidenote: Expedition against Dumnacus.] V. During this time, Caninius Rebilus, who had first been appointed to go into the country of the Ruteni, but who had been detained by partial insurrections in the region situated between the Creuse and the Vienne, learnt that numerous hostile bands were assembling in the country of the Pictones; he was informed of this by letters from Duratius, their king, who, amid the defection of a part of his people, had remained invariably faithful to the Romans. He started immediately for Lemonum (_Poitiers_). On the road, he learnt from prisoners that Duratius was shut up there, and besieged by several thousand men under the orders of Dumnacus, chief of the Andes. Rebilus, at the head of two weak legions, did not dare to measure his strength with the enemy; he contented himself with establishing his camp in a strong position. At the news of his approach, Dumnacus raised the siege, and marched to meet the legions. But, after several days’ fruitless attempts to force their camp, he returned to attack Lemonum.
