Their determination once taken, they fortified their _oppida_, and transported to them the wheat from their fields. Persuaded that the country of the Veneti would be the first attacked, they gathered together all their ships, no doubt in the vast estuary formed by the river Auray in the Bay of Quiberon. (_See Plate 12._) They allied themselves with the maritime peoples of the coast, from the mouth of the Loire to that of the Scheldt,[275] and demanded succour from the isle of Britain.[276] In spite of the difficulties of this war, Cæsar undertook it without hesitation. He was influenced by grave motives: the violation of the right of nations, the rebellion after submission, the coalition of so many peoples; above all, by the fear that their impunity would be an encouragement to others. If we believe Strabo, Cæsar, as well as the Veneti, had other reasons to desire this war: on one side, the latter, possessed of the commerce of Britain, already suspected the design of the Roman general to pass into that island, and they sought to deprive him of the means; and, on the other, Cæsar could not attempt the dangerous enterprise of a descent on England till after he had destroyed the fleet of the Veneti, the sole masters of the ocean.[277] [Sidenote: War against the Veneti.] II. Be this as it may, in order to prevent new risings, Cæsar divided his army so as to occupy the country militarily. The lieutenant T. Labienus, at the head of a part of the cavalry, was sent to the Treviri, with the mission to visit the Remi and other peoples of Belgic Gaul, to maintain them in their duty, and to oppose the passage of the Rhine by the Germans, who were said to have been invited by the Belgæ. P. Crassus was ordered, with twelve legionary cohorts, and a numerous body of cavalry, to repair into Aquitaine, to prevent the inhabitants of that province from swelling the forces of the insurrection. The lieutenant Q. Titurius Sabinus was detached with three legions to restrain the Unelli, the Curiosolitæ, and the Lexovii. The young D. Brutus,[278] who had arrived from the Mediterranean with the galleys,[279] received the command of the fleet, which was increased by the Gaulish ships borrowed from the Pictones, the Santones, and other peoples who had submitted. His instructions enjoined him to sail as soon as possible for the country of the Veneti. As to Cæsar, he proceeded thither with the rest of the land army. The eight legions of the Roman army were then distributed thus: to the north of the Loire, three legions; in Aquitaine, with Crassus, a legion and two cohorts; one legion, no doubt, on the fleet; and two legions and eight cohorts with the general-in-chief, to undertake the war against the Veneti.[280]
