Lucius Seneca - Yale Required Reading - Collected Works (Vol. 2)

The day following, the generals of his opponents, being alarmed that they had lost all prospect of supplies, and of access to the Ebro, consulted as to what other course they should take. There were two roads, one to Ilerda, if they chose to return, the other to Tarraco, if they should march to it. While they were deliberating on these matters, intelligence was brought them that their watering parties were attacked by our horse: upon which information, they dispose several parties of horse and auxiliary foot along the road, and intermix some legionary cohorts, and begin to throw up a rampart from the camp to the water, that they might be able to procure water within their lines, both without fear, and without a guard. Petreius and Afranius divided this task between themselves, and went in person to some distance from their camp for the purpose of seeing it accomplished.

The soldiers having obtained by their absence a free opportunity of conversing with each other, came out in great numbers, and inquired each for whatever acquaintance or fellow-citizen he had in our camp, and invited him to him. First they returned them general thanks for sparing them the day before, when they were greatly terrified, and acknowledged that they were alive through their kindness; then they inquired about the honor of our general, and whether they could with safety intrust themselves to him; and declared their sorrow that they had not done so in the beginning, and that they had taken up arms against their relations and kinsmen. Encouraged by these conferences, they desired the general's parole for the lives of Petreius and Afranius, that they might not appear guilty of a crime, in having betrayed their generals. When they were assured of obtaining their demands, they promised that they would immediately remove their standards, and sent centurions of the first rank as deputies to treat with Caesar about a peace. In the mean time some of them invite their acquaintances, and bring them to their camp, others are brought away by their friends, so that the two camps seemed to be united into one, and several of the tribunes and centurions came to Caesar, and paid their respects to him. The same was done by some of the nobility of Spain, whom they summoned to their assistance, and kept in their camp as hostages. They inquired after their acquaintance and friends, by whom each might have the means of being recommended to Caesar. Even Afranius's son, a young man, endeavored, by means of Sulpitius the lieutenant, to make terms for his own and his father's life. Every place was filled with mirth and congratulations; in the one army, because they thought they had escaped so impending danger; in the other, because they thought they had completed so important a matter without blows; and Caesar, in every man's judgment, reaped the advantage of his former lenity, and his conduct was applauded by all.

When these circumstances were announced to Afranius, he left the work which he had begun, and returned to his camp, determined as it appeared, whatever should be the event, to bear it with an even and steady mind. Petreius did not neglect himself; he armed his domestics; with them and the praetorian cohort of Spaniards, and a few foreign horse, his dependents, whom he commonly kept near him to guard his person, he suddenly flew to the rampart, interrupted the conferences of the soldiers, drove our men from the camp, and put to death as many as he caught. The rest formed into a body, and being alarmed by the unexpected danger, wrapped their left arms in their cloaks, and drew their swords, and in this manner, depending on the nearness of their camp, defended themselves against the Spaniards, and the horse, and made good their retreat to the camp, where they were protected by the cohorts which were on guard.

Petreius, after accomplishing this, went round every maniple, calling the soldiers by their names, and entreating with tears that they would not give up him and their absent general Pompey, as a sacrifice to the vengeance of their enemies. Immediately they ran in crowds to the general's pavilion, when he required them all to take an oath that they would not desert nor betray the army nor the generals, nor form any design distinct from the general interest. He himself swore first to the tenor of those words, and obliged Afranius to take the same oath. The tribunes and centurions followed their example; the soldiers were brought out by centuries, and took the same oath. They gave orders, that whoever had any of Caesar's soldiers should produce them; as soon as they were produced, they put them to death publicly in the praetorium, but most of them concealed those that they had entertained, and let them out at night over the rampart. Thus the terror raised by the generals, the cruelty of the punishments, the new obligation of an oath, removed all hopes of surrender for the present, changed the soldiers' minds, and reduced matters to the former state of war.

Caesar ordered the enemy's soldiers, who had come into his camp to hold a conference, to be searched for with the strictest diligence, and sent back. But of the tribunes and centurions, several voluntarily remained with him, and he afterward treated them with great respect. The centurions he promoted to higher ranks, and conferred on the Roman knights the honor of tribunes.

Afranius's men were distressed in foraging, and procured water with difficulty. The legionary soldiers had a tolerable supply of corn, because they had been ordered to bring from Ilerda sufficient to last twenty-two days; the Spanish and auxiliary forces had none, for they had but few opportunities of procuring any, and their bodies were not accustomed to bear burdens; and therefore a great number of them came over to Caesar every day. Their affairs were under these difficulties; but of the two schemes proposed, the most expedient seemed to be to return to Ilerda, because they had left some corn there; and there they hoped to decide on a plan for their future conduct. Tarraco lay at a greater distance; and in such a space they knew affairs might admit of many changes. Their design having met with approbation, they set out from their camp. Caesar having sent forward his cavalry, to annoy and retard their rear, followed close after with his legions. Not a moment passed in which their rear was not engaged with our horse.

Their manner of fighting was this: the light cohorts closed their rear, and frequently made a stand on the level grounds. If they had a mountain to ascend, the very nature of the place readily secured them from any danger; for the advanced guards, from the rising grounds, protected the rest in their ascent. When they approached a valley or declivity, and the advanced men could not impart assistance to the tardy, our horse threw their darts at them from the rising grounds with advantage; then their affairs were in a perilous situation; the only plan left was, that whenever they came near such places, they should give orders to the legions to halt, and by a violent effort repulse our horse; and these being forced to give way, they should suddenly, with the utmost speed, run all together down to the valley, and having passed it, should face about again on the next hill. For so far were they from deriving any assistance from their horse (of which they had a large number), that they were obliged to receive them into the center of their army, and themselves protect them, as they were daunted by former battles. And on their march no one could quit the line without being taken by Caesar's horse.

While skirmishes were fought in this manner, they advanced but slowly and gradually, and frequently halted to help their rear, as then happened. For having advanced four miles, and being very much harassed by our horse, they took post on a high mountain, and there in trenched themselves on the front only, facing the enemy; and did not take their baggage off their cattle. When they perceived that Caesar's camp was pitched, and the tents fixed up, and his horse sent out to forage, they suddenly rushed out about twelve o'clock the same day, and, having hopes that we should be delayed by the absence of our horse, they began to march, which Caesar perceiving, followed them with the legions that remained. He left a few cohorts to guard his baggage, and ordered the foragers to be called home at the tenth hour, and the horse to follow him. The horse shortly returned to their daily duty on march, and charged the rear so vigorously, that they almost forced them to fly; and several privates and some centurions were killed. The main body of Caesar's army was at hand, and universal ruin threatened them.
