[-19-] At the same time that these events were happening in the City Aulus Plautius, a senator of great renown, made a campaign against Britain. The cause was that a certain Bericus, who had been ejected from the island during a revolution, had persuaded Claudius to send a body of troops there. This Plautius after he was made general had difficulty in leading his army beyond Gaul. The soldiers objected, on the ground that their operations were to take place outside the limits of the known world, and would not yield him obedience until the arrival of Narcissus, sent by Claudius, who mounted the tribunal of Plautius and tried to address them. This made them more irritated than ever and they would not allow the newcomer to say a word, but all suddenly shouted together the well-known phrase: "Ho! Ho! the Saturnalia!" (For at the festival of Saturn slaves celebrate the occasion by donning their masters' dress.) After this they at once followed Plautius voluntarily, but their delay had brought the expedition late in the season. Three divisions were made, in order that they might not be hindered in advancing (as might happen to a single force), and some of them in their voyage across became discouraged because they were buffeted into a backward course, whereas others acquired confidence from the fact that a flash of light starting from the east shot across to the west, the direction in which they were sailing. So they came to anchor on the shore of the island and found no one to oppose them. The Britons as a result of their inquiries had not expected that they would come and had therefore not assembled beforehand. Nor even at this time would they come into closer conflict with the invaders, but took refuge in the swamps and in the forests, hoping to exhaust their opponents in some other way, so that the latter as in the days of Julius Cæsar would sail back empty-handed. [-20-] Plautius accordingly had considerable trouble in searching for them.--They were not free and independent but were parceled out among various kings.--When at last he did find them, he conquered first Caratacus and next Togodumnus, children of Cynobelinus, who was dead. After the flight of those kings he attached by treaty a portion of the Bodunni, ruled by a nation of the Catuellani. Leaving a garrison there he advanced farther. On reaching a certain river, which the barbarians thought the Romans would not be able to cross without a bridge,--a conviction which led them to encamp in rather careless fashion on the opposite bank,--he sent ahead Celtæ who were accustomed to swim easily in full armor across the most turbulent streams. These fell unexpectedly upon the enemy, but instead of shooting at any of the men confined themselves to wounding the horses that drew their chariots and consequently in the confusion not even the mounted warriors could save themselves. Plautius sent across also Fiavius Vespasian, who afterward obtained the imperial office, and his brother Sabinus, a lieutenant of his. So they likewise got over the river in some way and killed numbers of the foe, who were not aware of their approach. The survivors, however, did not take to flight, and on the next day joined issue with them again. The two forces were rather evenly matched until Gnæus Hosidius Geta, at the risk of being captured, managed to conquer the barbarians in such a way that he received triumphal honors without having ever been consul.
