"De Bello Gallico" and Other Commentaries

by Julius Caesar

LX.—In the meantime the Oscenses and the Calagurritani, who were under the government of the Oscenses, send ambassadors to Caesar, and offer to submit to his orders. They are followed by the Tarraconenses, Jacetani, and Ausetani, and in a few days more by the Illurgavonenses, who dwell near the river Ebro. He requires of them all to assist him with corn, to which they agreed, and having collected all the cattle in the country, they convey them into his camp. One entire cohort of the Illurgavonenses, knowing the design of their state, came over to Caesar, from the place where they were stationed, and carried their colours with them. A great change is shortly made in the face of affairs. The bridge being finished, five powerful states being joined to Caesar, a way opened for the receiving of corn, and the rumours of the assistance of legions which were said to be on their march, with Pompey at their head, through Mauritania, having died away, several of the more distant states revolt from Afranius, and enter into league with Caesar.

LXI.—Whilst the spirits of the enemy were dismayed at these things, Caesar, that he might not be always obliged to send his horse a long circuit round by the bridge, having found a convenient place, began to sink several drains, thirty feet deep, by which he might draw off a part of the river Segre, and make a ford over it. When these were almost finished, Afranius and Petreius began to be greatly alarmed, lest they should be altogether cut off from corn and forage, because Caesar was very strong in cavalry. They therefore resolved to quit their posts, and to transfer the war to Celtiberia. There was, moreover, a circumstance that confirmed them in this resolution: for of the two adverse parties, that which had stood by Sertorius in the late war, being conquered by Pompey, still trembled at his name and sway, though absent: the other which had remained firm in Pompey's interest, loved him for the favours which they had received: but Caesar's name was not known to the barbarians. From these they expected considerable aid, both of horse and foot, and hoped to protract the war till winter, in a friendly country. Having come to this resolution, they gave orders to collect all the ships in the river Ebro, and to bring them to Octogesa, a town situated on the river Ebro, about twenty miles distant from their camp. At this part of the river, they ordered a bridge to be made of boats fastened together, and transported two legions over the river Segre, and fortified their camp with a rampart, twelve feet high.

LXII.—Notice of this being given by the scouts, Caesar continued his work day and night, with very great fatigue to the soldiers, to drain the river, and so far effected his purpose, that the horse were both able and bold enough, though with some difficulty and danger, to pass the river; but the foot had only their shoulders and upper part of their breast above the water, so that their fording it was retarded, not only by the depth of the water, but also by the rapidity of the current. However, almost at the same instant, news was received of the bridge being nearly completed over the Ebro, and a ford was found in the Segre.

LXIII.—Now indeed the enemy began to think that they ought to hasten their march. Accordingly, leaving two auxiliary cohorts in the garrison at Ilerda, they crossed the Segre with their whole force, and formed one camp with the two legions which they had led across a few days before. Caesar had no resource, but to annoy and cut down their rear; since with his cavalry to go by the bridge, required him to take a long circuit; so that they would arrive at the Ebro by a much shorter route. The horse, which he had detached, crossed the ford, and when Afranius and Petreius had broken up their camp about the third watch, they suddenly appeared on their rear, and spreading round them in great numbers, began to retard and impede their march.

LXIV.—At break of day, it was perceived from the rising grounds which joined Caesar's camp, that their rear was vigorously pressed by our horse; that the last line sometimes halted and was broken; at other times, that they joined battle and that our men were beaten back by a general charge of their cohorts, and, in their turn, pursued them when they wheeled about: but through the whole camp the soldiers gathered in parties, and declared their chagrin that the enemy had been suffered to escape from their hands and that the war had been unnecessarily protracted. They applied to their tribunes and centurions, and entreated them to inform Caesar that he need not spare their labour or consider their danger; that they were ready and able, and would venture to ford the river where the horse had crossed. Caesar, encouraged by their zeal and importunity, though he felt reluctant to expose his army to a river so exceedingly large, yet judged it prudent to attempt it and make a trial. Accordingly, he ordered all the weaker soldiers, whose spirit or strength seemed unequal to the fatigue, to be selected from each century, and left them, with one legion besides, to guard the camp: the rest of the legions he drew out without any baggage, and, having disposed a great number of horses in the river, above and below the ford, he led his army over. A few of his soldiers being carried away by the force of the current, were stopped by the horse and taken up, and not a man perished. His army being safe on the opposite bank, he drew out his forces and resolved to lead them forward in three battalions: and so great was the ardour of the soldiers that, notwithstanding the addition of a circuit of six miles and a considerable delay in fording the river, before the ninth hour of the day they came up with those who had set out at the third watch.

LXV.—When Afranius, who was in company with Petreius, saw them at a distance, being affrighted at so unexpected a sight, he halted on a rising ground and drew up his army. Caesar refreshed his army on the plain that he might not expose them to battle whilst fatigued; and when the enemy attempted to renew their march, he pursued and stopped them. They were obliged to pitch their camp sooner than they had intended, for there were mountains at a small distance; and difficult and narrow roads awaited them about five miles off. They retired behind these mountains that they might avoid Caesar's cavalry, and, placing parties in the narrow roads, stop the progress of his army and lead their own forces across the Ebro without danger or apprehension. This it was their interest to attempt and to effect by any means possible; but, fatigued by the skirmishes all day, and by the labour of their march, they deferred it till the following day: Caesar likewise encamped on the next hill.

LXVI.—About midnight a few of their men who had gone some distance from the camp to fetch water, being taken by our horse, Caesar is informed by them that the generals of the enemy were drawing their troops out of the camp without noise. Upon this information Caesar ordered the signal to be given and the military shout to be raised for packing up the baggage. When they heard the shout, being afraid lest they should be stopped in the night and obliged to engage under their baggage, or lest they should be confined in the narrow roads by Caesar's horse, they put a stop to their march and kept their forces in their camp. The next day Petreius went out privately with a few horse to reconnoitre the country. A similar movement was made from Caesar's camp. Lucius Decidius Saxa was detached with a small party to explore the nature of the country. Each returned with the same account to his camp, that there was a level road for the next five miles, that there then succeeded a rough and mountainous country. Whichever should first obtain possession of the defiles would have no trouble in preventing the other's progress.

LXVII.—There was a debate in the council between Afranius and Petreius, and the time of marching was the subject. The majority were of opinion that they should begin their march at night, "for they might reach the defiles before they should be discovered." Others, because a shout had been raised the night before in Caesar's camp, used this as an argument that they could not leave the camp unnoticed: "that Caesar's cavalry were patrolling the whole night, and that all the ways and roads were beset; that battles at night ought to be avoided, because in civil dissension, a soldier once daunted is more apt to consult his fears than his oath; that the daylight raised a strong sense of shame in the eyes of all, and that the presence of the tribunes and centurions had the same effect: by these things the soldiers would be re strained and awed to their duty. Wherefore they should, by all means, attempt to force their way by day; for, though a trifling loss might be sustained, yet the post which they desired might be secured with safety to the main body of the army." This opinion prevailed in the council, and the next day, at the dawn, they resolved to set forward.

LXVIII.—Caesar, having taken a view of the country, the moment the sky began to grow white, led his forces from the camp and marched at the head of his army by a long circuit, keeping to no regular road; for the road which led to the Ebro and Octogesa was occupied by the enemy's camp, which lay in Caesar's way. His soldiers were obliged to cross extensive and difficult valleys. Craggy cliffs, in several places, interrupted their march, insomuch that their arms had to be handed to one another, and the soldiers were forced to perform a great part of their march unarmed, and were lifted up the rocks by each other. But not a man murmured at the fatigue, because they imagined that there would be a period to all their toils if they could cut off the enemy from the Ebro and intercept their convoys.

LXIX.—At first, Afranius's soldiers ran in high spirits from their camp to look at us, and in contumelious language upbraided us, "that we were forced, for want of necessary subsistence, to run away, and return to Ilerda." For our route was different from what we proposed, and we appeared to be going a contrary way. But their generals applauded their own prudence in keeping within their camp, and it was a strong confirmation of their opinion, that they saw we marched without waggons or baggage, which made them confident that we could not long endure want. But when they saw our army gradually wheel to the right, and observed our van was already passing the line of their camp, there was nobody so stupid, or averse to fatigue, as not to think it necessary to march from the camp immediately, and oppose us. The cry to arms was raised, and all the army, except a few which were left to guard the camp, set out and marched the direct road to the Ebro.
