Gallic War

The Germans when, upon hearing a noise behind them, [they looked and] saw that their families were being slain, throwing away their arms and abandoning their standards, fled out of the camp, and when they had arrived at the confluence of the Meuse and the Rhine , the survivors despairing of further escape, as a great number of their countrymen had been killed, threw themselves into the river and there perished, overcome by fear, fatigue, and the violence of the stream. Our soldiers, after the alarm of so great a war, for the number of the enemy amounted to 430,000, returned to their camp, all safe to a man, very few being even wounded. Caesar granted those whom he had detained in the camp liberty of departing. They however, dreading revenge and torture from the Gauls, whose lands they had harassed, said that they desired to remain with him. Caesar granted them permission.

The German war being finished, Caesar thought it expedient for him to cross the Rhine , for many reasons; of which this was the most weighty, that, since he saw the Germans were so easily urged to go into Gaul, he desired they should have their fears for their own territories, when they discovered that the army of the Roman people both could and dared pass the Rhine . There was added also, that portion of the cavalry of the Usipetes and the Tenchtheri, which I have above related to have crossed the Meuse for the purpose of plundering and procuring forage, and was not present at the engagement, had betaken themselves, after the retreat of their countrymen, across the Rhine into the territories of the Sigambri, and united themselves to them. When Caesar sent embassadors to them, to demand that they should give up to him those who had made war against him and against Gaul, they replied, "That the Rhine bounded the empire of the Roman people; if he did not think it just for the Germans to pass over into Gaul against his consent, why did he claim that any thing beyond the Rhine should be subject to his dominion or power?" The Ubii, also, who alone, out of all the nations lying beyond the Rhine , had sent embassadors to Caesar, and formed an alliance and given hostages, earnestly entreated "that he would bring them assistance, because they were grievously oppressed by the Suevi; or, if he was prevented from doing so by the business of the commonwealth, he would at least transport his army over the Rhine ; that that would be sufficient for their present assistance and their hope for the future; that so great was the name and the reputation of his army, even among the most remote nations of the Germans, arising from the defeat of Ariovistus and this last battle which was fought, that they might be safe under the fame and friendship of the Roman people." They promised a large number of ships for transporting the army.

Caesar, for those reasons which I have mentioned, had resolved to cross the Rhine ; but to cross by ships he neither deemed to be sufficiently safe, nor considered consistent with his own dignity or that of the Roman people. Therefore, although the greatest difficulty in forming a bridge was presented to him, on account of the breadth, rapidity, and depth of the river, he nevertheless considered that it ought to be attempted by him, or that his army ought not otherwise to be led over. He devised this plan of a bridge. He joined together at the distance of two feet, two piles, each a foot and a half thick, sharpened a little at the lower end, and proportioned in length, to the depth of the river. After he had, by means of engines, sunk these into the river, and fixed them at the bottom, and then driven them in with rammers, not quite perpendicularly, like a stake, but bending forward and sloping, so as to incline in the direction of the current of the river; he also placed two [other piles] opposite to these, at the distance of forty feet lower down, fastened together in the same manner, but directed against the force and current of the river. Both these, moreover, were kept firmly apart by beams two feet thick (the space which the binding of the piles occupied), laid in at their extremities between two braces on each side, and in consequence of these being in different directions and fastened on sides the one opposite to the other, so great was the strength of the work, and such the arrangement of the materials, that in proportion as the greater body of water dashed against the bridge, so much the closer were its parts held fastened together. These beams were bound together by timber laid over them, in the direction of the length of the bridge, and were [then] covered over with laths and hurdles; and in addition to this, piles were driven into the water obliquely, at the lower side of the bridge, and these, serving as buttresses, and being connected with every portion of the work, sustained the force of the stream: and there were others also above the bridge, at a moderate distance; that if trunks of trees or vessels were floated down the river by the barbarians for the purpose of destroying the work, the violence of such things might be diminished by these defenses, and might not injure the bridge.

Within ten days after the timber began to be collected, the whole work was completed, and the whole army led over. Caesar, leaving a strong guard at each end of the bridge, hastens into the territories of the Sigambri. In the mean time, embassadors from several nations come to him, whom, on their suing for peace and alliance, he answers in a courteous manner, and orders hostages to be brought to him. But the Sigambri, at the very time the bridge was begun to be built, made preparations for a flight (by the advice of such of the Tenchtheri and Usipetes as they had among them), and quitted their territories, and conveyed away all their possessions, and concealed themselves in deserts and woods.

Caesar, having remained in their territories a few days, and burned all their villages and houses, and cut down their corn, proceeded into the territories of the Ubii; and having promised them his assistance, if they were ever harassed by the Suevi, he learned from them these particulars: that the Suevi, after they had by means of their scouts found that the bridge was being built, had called a council, according to their custom, and sent orders to all parts of their state to remove from the towns and convey their children, wives, and all their possessions into the woods, and that all who could bear arms should assemble in one place; that the place thus chosen was nearly the centre of those regions which the Suevi possessed; that in this spot they had resolved to await the arrival of the Romans, and give them battle there. When Caesar discovered this, having already accomplished all these things on account of which he had resolved to lead his army over, namely, to strike fear into the Germans, take vengeance on the Sigambri, and free the Ubii from the invasion of the Suevi, having spent altogether eighteen days beyond the Rhine , and thinking he had advanced far enough to serve both honor and interest, he returned into Gaul, and cut down the bridge.

During the short part of summer which remained, Caesar, although in these countries, as all Gaul lies toward the north, the winters are early, nevertheless resolved to proceed into Britain, because he discovered that in almost all the wars with the Gauls succors had been furnished to our enemy from that country; and even if the time of year should be insufficient for carrying on the war, yet he thought it would be of great service to him if he only entered the island, and saw into the character of the people, and got knowledge of their localities, harbors, and landing-places, all which were for the most part unknown to the Gauls. For neither does any one except merchants generally go thither, nor even to them was any portion of it known, except the sea-coast and those parts which are opposite to Gaul. Therefore, after having called up to him the merchants from all parts, he could learn neither what was the size of the island, nor what or how numerous were the nations which inhabited it, nor what system of war they followed, nor what customs they used, nor what harbors were convenient for a great number of large ships.

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.

While Caesar remains in these parts for the purpose of procuring ships, embassadors come to him from a great portion of the Morini, to plead their excuse respecting their conduct on the late occasion; alleging that it was as men uncivilized, and as those who were unacquainted with our custom, that they had made war upon the Roman people, and promising to perform what he should command. Caesar, thinking that this had happened fortunately enough for him, because he neither wished to leave an enemy behind him, nor had an opportunity for carrying on a war, by reason of the time of year, nor considered that employment in such trifling matters was to be preferred to his enterprise on Britain, imposes a large number of hostages; and when these were brought, he received them to his protection. Having collected together, and provided about eighty transport ships, as many as he thought necessary for conveying over two legions, he assigned such [ships] of war as he had besides to the quaestor, his lieutenants, and officers of cavalry. There were in addition to these eighteen ships of burden which were prevented, eight miles from that place, by winds, from being able to reach the same port. These he distributed among the horse; the rest of the army, he delivered to Q. Titurius Sabinus and L. Aurunculeius Cotta, his lieutenants, to lead into the territories of the Menapii and those cantons of the Morini from which embassadors had not come to him. He ordered P. Sulpicius Rufus, his lieutenant, to hold possession of the harbor, with such a garrison as he thought sufficient.
