XI.--These things being known [to him], Caesar orders the legions and cavalry to be recalled and to cease from their march; he himself returns to the ships: he sees clearly before him almost the same things which he had heard of from the messengers and by letter, so that, about forty ships being lost, the remainder seemed capable of being repaired with much labour. Therefore he selects workmen from the legions, and orders others to be sent for from the continent; he writes to Labienus to build as many ships as he could with those legions which were with him. He himself, though the matter was one of great difficulty and labour, yet thought it to be most expedient for all the ships to be brought up on shore and joined with the camp by one fortification. In these matters he employed about ten days, the labour of the soldiers being unremitting even during the hours of night. The ships having been brought up on shore and the camp strongly fortified, he left the same forces which he did before as a guard for the ships; he sets out in person for the same place that he had returned from. When he had come thither, greater forces of the Britons had already assembled at that place, the chief command and management of the war having been entrusted to Cassivellaunus, whose territories a river, which is called the Thames, separates from the maritime states at about eighty miles from the sea. At an earlier period perpetual wars had taken place between him and the other states; but, greatly alarmed by our arrival, the Britons had placed him over the whole war and the conduct of it.
XIX.--Cassivellaunus, as we have stated above, all hope [rising out] of battle being laid aside, the greater part of his forces being dismissed, and about 4000 charioteers only being left, used to observe our marches and retire a little from the road, and conceal himself in intricate and woody places, and in those neighbourhoods in which he had discovered we were about to march, he used to drive the cattle and the inhabitants from the fields into the woods; and, when our cavalry, for the sake of plundering and ravaging the more freely, scattered themselves among the fields, he used to send out charioteers from the woods by all the well-known roads and paths, and, to the great danger of our horse, engage with them; and this source of fear hindered them from straggling very extensively. The result was that Caesar did not allow excursions to be made to a great distance from the main body of the legions, and ordered that damage should be done to the enemy in ravaging their lands and kindling fires only so far as the legionary soldiers could, by their own exertion and marching, accomplish it.
XX.--In the meantime, 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 ambassadors 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.
XXII.--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 ambassadors 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.
