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 everything. In the same place, the cavalry of the whole of Gaul, in number 4000, assembles, and also the chief persons of all the states; he had determined to leave in Gaul a very few of them, whose fidelity towards 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 ambassadors 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 honour 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 honour 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 farther and farther, 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 favourable 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 homewards 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 2000 horse, to defend the harbours 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 sunset and though for a time borne forward by a gentle southwest 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 port 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 labour of rowing not being for a moment discontinued, equalled the speed of the ships of war. All the ships reached Britain nearly at midday; nor was there seen a single enemy in that place, but, as Caesar afterwards found from some prisoners, though large bodies of
