Gallic War (5.5-5.9)

These matters being settled, Caesar went to port Itius with the legions. There he discovers that forty[*] ships, which had been built in the country of the Meldi , having been driven back by a storm, had been unable to maintain their course, and had returned to the same port from which they had set out; he finds the rest ready for sailing, and furnished with every thing. In the same place, the cavalry of the whole of Gaul, in number 4,000, assembles, and [also] the chief persons of all the states; he had determined to leave in Gaul a very few of them, whose fidelity toward him he had clearly discerned, and take the rest with him as hostages; because he feared a commotion in Gaul when he should be absent.

There was together with the others, Dumnorix, the Aeduan, of whom we have made previous mention. Him, in particular, he had resolved to have with him, because he had discovered him to be fond of change, fond of power, possessing great resolution, and great influence among the Gauls. To this was added, that Dumnorix had before said in an assembly of Aeduans, that the sovereignty of the state had been made over to him by Caesar; which speech the Aedui bore with impatience and yet dared not send embassadors to Caesar for the purpose of either rejecting or deprecating [that appointment]. That fact Caesar had learned from his own personal friends. He at first strove to obtain by every entreaty that he should be left in Gaul; partly, because, being unaccustomed to sailing, he feared the sea; partly because he said he was prevented by divine admonitions. After he saw that this request was firmly refused him, all hope of success being lost, he began to tamper with the chief persons of the Gauls, to call them apart singly and exhort them to remain on the continent; to agitate them with the fear that it was not without reason that Gaul should be stripped of all her nobility; that it was Caesar's design, to bring over to Britain and put to death all those whom he feared to slay in the sight of Gaul, to pledge his honor to the rest, to ask for their oath that they would by common deliberation execute what they should perceive to be necessary for Gaul. These things were reported to Caesar by several persons.

Having learned this fact, Caesar, because he had conferred so much honor upon the Aeduan state, determined that Dumnorix should be restrained and deterred by whatever means he could; and that, because he perceived his insane designs to be proceeding further and further, care should be taken lest he might be able to injure him and the commonwealth. Therefore, having stayed about twenty-five days in that place, because the north wind, which usually blows a great part of every season, prevented the voyage, he exerted himself to keep Dumnorix in his allegiance [and] nevertheless learn all his measures: having at length met with favorable weather, he orders the foot soldiers and the horse to embark in the ships. But, while the minds of all were occupied, Dumnorix began to take his departure from the camp homeward with the cavalry of the Aedui, Caesar being ignorant of it. Caesar, on this matter being reported to him, ceasing from his expedition and deferring all other affairs, sends a great part of the cavalry to pursue him, and commands that he be brought back; he orders that if he use violence and do not submit, that he be slain; considering that Dumnorix would do nothing as a rational man while he himself was absent, since he had disregarded his command even when present. He, however, when recalled, began to resist and defend himself with his hand, and implore the support of his people, often exclaiming that "he was free and the subject of a free state." They surround and kill the man as they had been commanded; but the Aeduan horsemen all return to Caesar.

When these things were done [and] Labienus, left on the continent with three legions and 2,000 horse, to defend the harbors and provide corn, and discover what was going on in Gaul, and take measures according to the occasion and according to the circumstance; he himself, with five legions and a number of horse, equal to that which he was leaving on the continent, set sail at sun-set, and [though for a time] borne forward by a gentle south-west wind, he did not maintain his course, in consequence of the wind dying away about midnight, and being carried on too far by the tide, when the sun rose, espied Britain passed on his left. Then, again, following the change of tide, he urged on with the oars that he might make that part of the island in which he had discovered the preceding summer, that there was the best landing-place, and in this affair the spirit of our soldiers was very much to be extolled; for they with the transports and heavy ships, the labor of rowing not being [for a moment] discontinued, equaled the speed of the ships of war. All the ships reached Britain nearly at mid-day; nor was there seen a [single] enemy in that place, but, as Caesar afterward found from some prisoners, though large bodies of troops had assembled there, yet being alarmed by the great number of our ships, more than eight hundred of which, including the ships of the preceding year, and those private vessels which each had built for his own convenience, had appeared at one time, they had quitted the coast and concealed themselves among the higher points.

Caesar, having disembarked his army and chosen a convenient place for the camp, when he discovered from the prisoners in what part the forces of the enemy had lodged themselves, having left ten cohorts and 300 horse at the sea, to be a guard to the ships, hastens to the enemy, at the third watch, fearing the less for the ships, for this reason because he was leaving them fastened at anchor upon an even and open shore; and he placed Q. Atrius over the guard of the ships. He himself, having advanced by night about twelve miles, espied the forces of the enemy. They, advancing to the river with their cavalry and chariots from the higher ground, began to annoy our men and give battle. Being repulsed by our cavalry, they concealed themselves in woods, as they had secured a place admirably fortified by nature and by art, which, as it seemed, they had before prepared on account of a civil war; for all entrances to it were shut up by a great number of felled trees. They themselves rushed out of the woods to fight here and there, and prevented our men from entering their fortifications. But the soldiers of the seventh legion, having formed a testudo and thrown up a rampart against the fortification, took the place and drove them out of the woods, receiving only a few wounds. But Caesar forbade his men to pursue them in their flight any great distance; both because he was ignorant of the nature of the ground, and because, as a great part of the day was spent, he wished time to be left for the fortification of the camp.
