Gallic War (5.20-5.24)

In the mean time, the Trinobantes, almost the most powerful state of those parts, from which the young man, Mandubratius embracing the protection of Caesar had come to the continent of Gaul to [meet] him (whose father, Imanuentius, had possessed the sovereignty in that state, and had been killed by Cassivellaunus; he himself had escaped death by flight), send embassadors to Caesar, and promise that they will surrender themselves to him and perform his commands; they entreat him to protect Mandubratius from the violence of Cassivellaunus, and send to their state some one to preside over it, and possess the government. Caesar demands forty hostages from them, and corn for his army, and sends Mandubratius to them. They speedily performed the things demanded, and sent hostages to the number appointed, and the corn.

The Trinobantes being protected and secured from any violence of the soldiers, the Cenimagni, the Segontiaci, the Ancalites, the Bibroci, and the Cassi, sending embassies, surrendered themselves to Caesar. From them he learns that the capital town of Cassivellaunus was not far from that place, and was defended by woods and morasses, and a very large number of men and of cattle had been collected in it. (Now the Britons, when they have fortified the intricate woods, in which they are wont to assemble for the purpose of avoiding the incursion of an enemy, with an intrenchment and a rampart, call them a town.) Thither he proceeds with his legions: he finds the place admirably fortified by nature and art; he, however, undertakes to attack it in two directions. The enemy, having remained only a short time, did not sustain the attack of our soldiers, and hurried away on the other side of the town. A great amount of cattle was found there, and many of the enemy were taken and slain in their flight.

While these things are going forward in those places, Cassivellaunus sends messengers into Kent , which, we have observed above, is on the sea, over which districts four several kings reigned, Cingetorix, Carvilius, Taximagulus and Segonax, and commands them to collect all their forces, and unexpectedly assail and storm the naval camp. When they had come to the camp, our men, after making a sally, slaying many of their men, and also capturing a distinguished leader named Lugotorix, brought back their own men in safety. Cassivellaunus, when this battle was reported to him as so many losses had been sustained, and his territories laid waste, being alarmed most of all by the desertion of the states, sends embassadors to Caesar [to treat] about a surrender through the mediation of Commius the Atrebatian. Caesar, since he had determined to pass the winter on the continent, on account of the sudden revolts of Gaul, and as much of the summer did not remain, and he perceived that even that could be easily protracted, demands hostages, and prescribes what tribute Britain should pay each year to the Roman people; he forbids and commands Cassivellaunus that he wage not war against Mandubratius or the Trinobantes.

When he had received the hostages, he leads back the army to the sea, and finds the ships repaired. After launching these, because he had a large number of prisoners, and some of the ships had been lost in the storm, he determines to convey back his army at two embarkations. And it so happened, that out of so large a number of ships, in so many voyages, neither in this nor in the previous year was any ship missing which conveyed soldiers; but very few out of those which were sent back to him from the continent empty, as the soldiers of the former convoy had been disembarked, and out of those (sixty in number) which Labienus had taken care to have built, reached their destination; almost all the rest were driven back, and when Caesar had waited for them for some time in vain, lest he should be debarred from a voyage by the season of the year, inasmuch as the equinox was at hand, he of necessity stowed his soldiers the more closely, and, a very great calm coming on, after he had weighed anchor at the beginning of the second watch, he reached land at break of day and brought in all the ships in safety.

The ships having been drawn up and a general assembly of the Gauls held at Samarobriva, because the corn that year had not prospered in Gaul by reason of the droughts, he was compelled to station his army in its winter-quarters differently from the former years, and to distribute the legions among several states: one of them he gave to C. Fabius, his lieutenant, to be marched into the territories of the Morini; a second to Q. Cicero, into those of the Nervii; a third to L. Roscius, into those of the Essui; a fourth he ordered to winter with T. Labienus among the Remi in the confines of the Treviri ; he stationed three in Belgium ; over these he appointed M. Crassus, his questor, and L. Munatius Plancus and C. Trebonius, his lieutenants. One legion which he had raised last on the other side of the Po, and five cohorts, he sent among the Eburones, the greatest portion of whom lie between the Meuse and the Rhine , [and] who were under the government of Ambiorix and Cativolcus. He ordered Q. Titurius Sabinus and L. Aurunculeius Cotta, his lieutenants, to take command of these soldiers. The legions being distributed in this manner, he thought he could most easily remedy the scarcity of corn and yet the winter-quarters of all these legions (except that which he had given to L. Roscius, to be led into the most peaceful and tranquil neighborhood) were comprehended within [about] 100 miles. He himself in the mean while, until he had stationed the legions and knew that the several winter-quarters were fortified, determined to stay in Gaul.
