C. Julius Caesar, Gallic War

Caius Fabius set off with the rest of the army to the Carnutes and those other states, whose force he was informed, had served as auxiliaries in that battle, which he fought against Dumnacus. For he had no doubt that they would be more submissive after their recent sufferings, but if respite and time were given them, they might be easily excited by the earnest solicitations of the same Dumnacus. On this occasion Fabius was extremely fortunate and expeditious in recovering the states. For the Carnutes, who, though often harassed had never mentioned peace, submitted and gave hostages: and the other states, which lie in the remotest parts of Gaul, adjoining the ocean, and which are called Armoricae, influenced by the example of the Carnutes, as soon as Fabius arrived with his legions, without delay comply with his command. Dumnacus, expelled from his own territories, wandering and skulking about, was forced to seek refuge by himself in the most remote parts of Gaul.
