[5.1] Lucius Domitius and Appius Claudius being consuls, Caesar, when departing from his winter quarters into Italy, as he had been accustomed to do yearly, commands the lieutenants whom he appointed over the legions to take care that during the winter as many ships as possible should be built, and the old repaired. He plans the size and shape of them. For dispatch of lading, and for drawing them on shore, he makes them a little lower than those which we have been accustomed to use in our sea; and that so much the more, because he knew that, on account of the frequent changes of the tide, less swells occurred there; for the purpose of transporting burdens and a great number of horses, [he makes them] a little broader than those which we use in other seas. All these he orders to be constructed for lightness and expedition, to which object their lowness contributes greatly. He orders those things which are necessary for equipping ships to be brought thither from Spain. He himself, on the assizes of Hither Gaul being concluded, proceeds into Illyricum, because he heard that the part of the province nearest them was being laid waste by the incursions of the Pirustae. When he had arrived there, he levies soldiers upon the states, and orders them to assemble at an appointed place. Which circumstance having been reported [to them], the Pirustae send embassadors to him to inform him that no part of those proceedings was done by public deliberation, and assert that they were ready to make compensation by all means for the injuries [inflicted]. Caesar, accepting their defense, demands hostages, and orders them to be brought to him on a specified day, and assures them that unless they did so he would visit their state with war. These being brought to him on the day which he had ordered, he appoints arbitrators between the states, who should estimate the damages and determine the reparation.
[5.2] These things being finished, and the assizes being concluded, he returns into Hither Gaul, and proceeds thence to the army. When he had arrived there, having made a survey of the winter quarter, he finds that, by the extraordinary ardor of the soldiers, amid the utmost scarcity of all materials, about six hundred ships of that kind which we have described above and twenty-eight ships of war, had been built, and were not far from that state, that they might be launched in a few days. Having commended the soldiers and those who had presided over the work, he informs them what he wishes to be done, and orders all the ships to assemble at port Itius, from which port he had learned that the passage into Britain was shortest, [being only] about thirty miles from the continent. He left what seemed a sufficient number of soldiers for that design; he himself proceeds into the territories of the Treviri with four legions without baggage, and 800 horse, because they neither came to the general diets [of Gaul], nor obeyed his commands, and were moreover, said to be tampering with the Germans beyond the Rhine.
[5.3] This state is by far the most powerful of all Gaul in cavalry, and has great forces of infantry, and as we have remarked above, borders on the Rhine. In that state, two persons, Indutiomarus and Cingetorix, were then contending with each other for the supreme power; one of whom, as soon as the arrival of Caesar and his legions was known, came to him; assures him that he and all his party would continue in their allegiance, and not revolt from the alliance of the Roman people, and informs him of the things which were going on among the Treviri. But Indutiomarus began to collect cavalry and infantry, and make preparations for war, having concealed those who by reason of their age could not be under arms, in the forest Arduenna, which is of immense size, [and] extends from the Rhine across the country of the Treviri to the frontiers of the Remi. But after that, some of the chief persons of the state, both influenced by their friendship for Cingetorix, and alarmed at the arrival of our army, came to Caesar and began to solicit him privately about their own interests, since they could not provide for the safety of the state; Indutiomarus, dreading lest he should be abandoned by all, sends embassadors to Caesar, to declare that he absented himself from his countrymen, and refrained from coming to him on this account, that he might the more easily keep the state in its allegiance, lest on the departure of all the nobility the commonalty should, in their indiscretion, revolt. And thus the whole state was at his control; and that he, if Caesar would permit, would come to the camp to him, and would commit his own fortunes and those of the state to his good faith.
[5.4] Caesar, though he discerned from what motive these things were said, and what circumstances deterred him from his meditated plan, still, in order that he might not be compelled to waste the summer among the Treviri, while all things were prepared for the war with Britain, ordered Indutiomarus to come to him with 200 hostages. When they were brought, [and] among them his son and near relations, whom he had demanded by name, he consoled Indutiomarus, and enjoined him to continue in his allegiance; yet, nevertheless, summoning to him the chief men of the Treviri, he reconciled them individually to Cingetorix: this he both thought should be done by him in justice to the merits of the latter, and also judged that it was of great importance that the influence of one whose singular attachment toward him he had fully seen, should prevail as much as possible among his people. Indutiomarus was very much offended at this act, [seeing that] his influence was diminished among his countrymen; and he, who already before had borne a hostile mind toward us, was much more violently inflamed against us through resentment at this.
[5.5] 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 every thing. In the same place, the cavalry of the whole of Gaul, in number 4,000, assembles, and [also] the chief persons of all the states; he had determined to leave in Gaul a very few of them, whose fidelity toward 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.
[5.6] 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 embassadors 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 honor 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.
[5.7] Having learned this fact, Caesar, because he had conferred so much honor 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 further and further, 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 favorable 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 homeward 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.
[5.8] When these things were done [and] Labienus, left on the continent with three legions and 2,000 horse, to defend the harbors 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 sun-set, and [though for a time] borne forward by a gentle south-west 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 part 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 labor of rowing not being [for a moment] discontinued, equaled the speed of the ships of war. All the ships reached Britain nearly at mid-day; nor was there seen a [single] enemy in that place, but, as Caesar afterward found from some prisoners, though large bodies of troops had assembled there, yet being alarmed by the great number of our ships, more than eight hundred of which, including the ships of the preceding year, and those private vessels which each had built for his own convenience, had appeared at one time, they had quitted the coast and concealed themselves among the higher points.
[5.9] Caesar, having disembarked his army and chosen a convenient place for the camp, when he discovered from the prisoners in what part the forces of the enemy had lodged themselves, having left ten cohorts and 300 horse at the sea, to be a guard to the ships, hastens to the enemy, at the third watch, fearing the less for the ships, for this reason because he was leaving them fastened at anchor upon an even and open shore; and he placed Q. Atrius over the guard of the ships. He himself, having advanced by night about twelve miles, espied the forces of the enemy. They, advancing to the river with their cavalry and chariots from the higher ground, began to annoy our men and give battle. Being repulsed by our cavalry, they concealed themselves in woods, as they had secured a place admirably fortified by nature and by art, which, as it seemed, they had before prepared on account of a civil war; for all entrances to it were shut up by a great number of felled trees. They themselves rushed out of the woods to fight here and there, and prevented our men from entering their fortifications. But the soldiers of the seventh legion, having formed a testudo and thrown up a rampart against the fortification, took the place and drove them out of the woods, receiving only a few wounds. But Caesar forbade his men to pursue them in their flight any great distance; both because he was ignorant of the nature of the ground, and because, as a great part of the day was spent, he wished time to be left for the fortification of the camp.
[5.10] The next day, early in the morning, he sent both foot-soldiers and horse in three divisions on an expedition to pursue those who had fled. These having advanced a little way, when already the rear [of the enemy] was in sight, some horse came to Caesar from Quintus Atrius, to report that the preceding night, a very great storm having arisen, almost all the ships were dashed to pieces and cast upon the shore, because neither the anchors and cables could resist, nor could the sailors and pilots sustain the violence of the storm; and thus great damage was received by that collision of the ships.
[5.11] 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 labor. 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 labor, 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 labor 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 as 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 intrusted 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.
[5.12] The interior portion of Britain is inhabited by those of whom they say that it is handed down by tradition that they were born in the island itself: the maritime portion by those who had passed over from the country of the Belgae for the purpose of plunder and making war; almost all of whom are called by the names of those states from which being sprung they went thither, and having waged war, continued there and began to cultivate the lands. The number of the people is countless, and their buildings exceedingly numerous, for the most part very like those of the Gauls: the number of cattle is great. They use either brass or iron rings, determined at a certain weight, as their money. Tin is produced in the midland regions; in the maritime, iron; but the quantity of it is small: they employ brass, which is imported. There, as in Gaul, is timber of every description, except beech and fir. They do not regard it lawful to eat the hare, and the cock, and the goose; they, however, breed them for amusement and pleasure. The climate is more temperate than in Gaul, the colds being less severe.
[5.13] The island is triangular in its form, and one of its sides is opposite to Gaul. One angle of this side, which is in Kent, whither almost all ships from Gaul are directed, [looks] to the east; the lower looks to the south. This side extends about 500 miles. Another side lies toward Spain and the west, on which part is Ireland, less, as is reckoned, than Britain, by one half: but the passage [from it] into Britain is of equal distance with that from Gaul. In the middle of this voyage, is an island, which is called Mona: many smaller islands besides are supposed to lie [there], of which islands some have written that at the time of the winter solstice it is night there for thirty consecutive days. We, in our inquiries about that matter, ascertained nothing, except that, by accurate measurements with water, we perceived the nights to be shorter there than on the continent. The length of this side, as their account states, is 700 miles. The third side is toward the north, to which portion of the island no land is opposite; but an angle of that side looks principally toward Germany. This side is considered to be 800 miles in length. Thus the whole island is [about] 2,000 miles in circumference.
[5.14] The most civilized of all these nations are they who inhabit Kent, which is entirely a maritime district, nor do they differ much from the Gallic customs. Most of the inland inhabitants do not sow corn, but live on milk and flesh, and are clad with skins. All the Britains, indeed, dye themselves with wood, which occasions a bluish color, and thereby have a more terrible appearance in fight. They wear their hair long, and have every part of their body shaved except their head and upper lip. Ten and even twelve have wives common to them, and particularly brothers among brothers, and parents among their children; but if there be any issue by these wives, they are reputed to be the children of those by whom respectively each was first espoused when a virgin.
[5.15] The horse and charioteers of the enemy contended vigorously in a skirmish with our cavalry on the march; yet so that our men were conquerors in all parts, and drove them to their woods and hills; but, having slain a great many, they pursued too eagerly, and lost some of their men. But the enemy, after some time had elapsed, when our men were off their guard, and occupied in the fortification of the camp, rushed out of the woods, and making an attack upon those who were placed on duty before the camp, fought in a determined manner; and two cohorts being sent by Caesar to their relief, and these severally the first of two legions, when these had taken up their position at a very small distance from each other, as our men were disconcerted by the unusual mode of battle, the enemy broke through the middle of them most courageously, and retreated thence in safety. That day, Q. Laberius Durus, a tribune of the soldiers, was slain. The enemy, since more cohorts were sent against them, were repulsed.
[5.16] In the whole of this method of fighting since the engagement took place under the eyes of all and before the camp, it was perceived that our men, on account of the weight of their arms, inasmuch as they could neither pursue [the enemy when] retreating, nor dare quit their standards, were little suited to this kind of enemy; that the horse also fought with great danger, because they [the Britons] generally retreated even designedly, and, when they had drawn off our men a short distance from the legions, leaped from their chariots and fought on foot in unequal [and to them advantageous] battle. But the system of cavalry engagement is wont to produce equal danger, and indeed the same, both to those who retreat and to those who pursue. To this was added, that they never fought in close order, but in small parties and at great distances, and had detachments placed [in different parts], and then the one relieved the other, and the vigorous and fresh succeeded the wearied.
[5.17] The following day the enemy halted on the hills, a distance from our camp, and presented themselves in small parties, and began to challenge our horse to battle with less spirit than the day before. But at noon, when Caesar had sent three legions, and all the cavalry, with C. Trebonius, the lieutenant, for the purpose of foraging, they flew upon the foragers suddenly from all quarters, so that they did not keep off [even] from the standards and the legions. Our men making an attack on them vigorously, repulsed them; nor did they cease to pursue them until the horse, relying on relief, as they saw the legions behind them, drove the enemy precipitately before them, and slaying a great number of them, did not give them the opportunity either of rallying, or halting, or leaping from their chariots. Immediately after this retreat, the auxiliaries who had assembled from all sides, departed; nor after that time did the enemy ever engage with us in very large numbers.
[5.18] Caesar, discovering their design, leads his army into the territories of Cassivellaunus to the river Thames; which river can be forded in one place only and that with difficulty. When he had arrived there, he perceives that numerous forces of the enemy were marshaled on the other bank of the river; the bank also was defended by sharp stakes fixed in front, and stakes of the same kind fixed under the water were covered by the river. These things being discovered from [some] prisoners and deserters, Caesar, sending forward the cavalry, ordered the legions to follow them immediately. But the soldiers advanced with such speed and such ardor, though they stood above the water by their heads only, that the enemy could not sustain the attack of the legions and of the horse, and quitted the banks, and committed themselves to flight.
[5.19] 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 4,000 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 neighborhoods 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.
[5.20] 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.
[5.21] 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.
[5.22] 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.
[5.23] 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.
