C. Julius Caesar, Gallic War

He sends before him Caius Volusenus with a ship of war, to acquire a knowledge of these particulars before he in person should make a descent into the island, as he was convinced that this was a judicious measure. He commissioned him to thoroughly examine into all matters, and then return to him as soon as possible. He himself proceeds to the Morini with all his forces. He orders ships from all parts of the neighboring countries, and the fleet which the preceding summer he had built for the war with the Veneti, to assemble in this place. In the mean time, his purpose having been discovered, and reported to the Britons by merchants, embassadors come to him from several states of the island, to promise that they will give hostages, and submit to the government of the Roman people. Having given them an audience, he after promising liberally, and exhorting them to continue in that purpose, sends them back to their own country, and [dispatches] with them Commius, whom, upon subduing the Atrebates, he had created king there, a man whose courage and conduct he esteemed, and who he thought would be faithful to him, and whose influence ranked highly in those countries. He orders him to visit as many states as he could, and persuade them to embrace the protection of the Roman people, and apprize them that he would shortly come thither. Volusenus, having viewed the localities as far as means could be afforded one who dared not leave his ship and trust himself to barbarians, returns to Caesar on the fifth day, and reports what he had there observed.
