XXXVII—Scipio, having stayed for two days in his camp, along the river Haliacmon, which ran between him and Domitius's camp, on the third day, at dawn, led his army across a ford, and having made a regular encampment the day following, drew up his forces in front of his camp. Domitius thought he ought not to show any reluctance, but should draw out his forces and hazard a battle. But as there was a plain six miles in breadth between the two camps, he posted his army before Scipio's camp; while the latter persevered in not quitting his entrenchment. However, Domitius with difficulty restrained his men, and prevented their beginning a battle; the more so as a rivulet with steep banks, joining Scipio's camp, retarded the progress of our men. When Scipio perceived the eagerness and alacrity of our troops to engage, suspecting that he should be obliged the next day, either to fight, against his inclination, or to incur great disgrace by keeping within his camp, though he had come with high expectation, yet by advancing rashly, made a shameful end; and at night crossed the river, without even giving the signal for breaking up the camp, and returned to the ground from which he came, and there encamped near the river, on an elevated situation. After a few days, he placed a party of horse in ambush in the night, where our men had usually gone to forage for several days before. And when Quintus Varus, commander of Domitius's horse, came there as usual, they suddenly rushed from their ambush. But our men bravely supported their charge, and returned quickly every man to his own rank, and in their turn, made a general charge on the enemy: and having killed about eighty of them, and put the rest to flight, retreated to their camp with the loss of only two men.
XXXVIII.—After these transactions, Domitius, hoping to allure Scipio to a battle, pretended to be obliged to change his position through want of corn, and having given the signal for decamping, advanced about three miles, and posted his army and cavalry in a convenient place, concealed from the enemy's view. Scipio being in readiness to pursue him, detached his cavalry and a considerable number of light infantry to explore Domitius's route. When they had marched a short way, and their foremost troops were within reach of our ambush, their suspicions being raised by the neighing of the horses, they began to retreat: and the rest who followed them, observing with what speed they retreated, made a halt. Our men, perceiving that the enemy had discovered their plot, and thinking it in vain to wait for any more, having got two troops in their power, intercepted them. Among them was Marcus Opimius, general of the horse, but he made his escape: they either killed or took prisoners all the rest of these two troops, and brought them to Domitius.
XXXIX.—Caesar, having drawn his garrisons out of the sea-ports, as before mentioned, left three cohorts at Oricum to protect the town, and committed to them the charge of his ships of war, which he had transported from Italy. Acilius, as lieutenant-general, had the charge of this duty and the command of the town; he drew the ships into the inner part of the harbour, behind the town, and fastened them to the shore, and sank a merchant-ship in the mouth of the harbour to block it up; and near it he fixed another at anchor, on which he raised a turret, and faced it to the entrance of the port, and filled it with soldiers, and ordered them to keep guard against any sudden attack.
XL.—Cneius, Pompey's son, who commanded the Egyptian fleet, having got intelligence of these things, came to Oricum, and weighed up the ship, that had been sunk, with a windlass, and by straining at it with several ropes, and attacked the other which had been placed by Acilius to watch the port with several ships, on which he had raised very high turrets, so that fighting as it were from an eminence, and sending fresh men constantly to relieve the fatigued, and at the same time attempting the town on all sides by land, with ladders and his fleet, in order to divide the force of his enemies, he overpowered our men by fatigue, and the immense number of darts, and took the ship, having beat off the men who were put on board to defend it, who, however, made their escape in small boats; and at the same time he seized a natural mole on the opposite side, which almost formed an island over against the town. He carried over land, into the inner part of the harbour, four galleys, by putting rollers under them, and driving them on with levers. Then attacking on both sides the ships of war which were moored to the shore, and were not manned, he carried off four of them, and set the rest on fire. After despatching this business, he left Decimus Laelius, whom he had taken away from the command of the Asiatic fleet, to hinder provisions from being brought into the town from Biblis and Amantia, and went himself to Lissus, where he attacked thirty merchantmen, left within the port by Antonius, and set them on fire. He attempted to storm Lissus, but being delayed three days by the vigorous defence of the Roman citizens who belonged to that district, and of the soldiers which Caesar had sent to keep garrison there, and having lost a few men in the assault, he returned without effecting his object.
XLI.—As soon as Caesar heard that Pompey was at Asparagium, he set out for that place with his army, and having taken the capital of the Parthinians on his march, where there was a garrison of Pompey's, he reached Pompey in Macedonia, on the third day, and encamped beside him; and the day following, having drawn out all his forces before his camp, he offered Pompey battle. But perceiving that he kept within his trenches, he led his army back to his camp, and thought of pursuing some other plan. Accordingly, the day following, he set out with all his forces by a long circuit, through a difficult and narrow road to Dyrrachium; hoping, either that Pompey would be compelled to follow him to Dyrrachium, or that his communication with it might be cut off, because he had deposited there all his provisions and mat['e]riel of war. And so it happened; for Pompey, at first not knowing his design, because he imagined he had taken a route in a different direction from that country, thought that the scarcity of provisions had obliged him to shift his quarters; but having afterwards got true intelligence from his scouts, he decamped the day following, hoping to prevent him by taking a shorter road; which Caesar suspecting might happen, encouraged his troops to submit cheerfully to the fatigue, and having halted a very small part of the night, he arrived early in the morning at Dyrrachium, when the van of Pompey's army was visible at a distance, and there he encamped.
XLII.—Pompey, being cut off from Dyrrachium, as he was unable to effect his purpose, took a new resolution, and entrenched himself strongly on a rising ground, which is called Petra, where ships of a small size can come in, and be sheltered from some winds. Here he ordered a part of his men-of-war to attend him, and corn and provisions to be brought from Asia, and from all the countries of which he kept possession. Caesar, imagining that the war would be protracted to too great a length, and despairing of his convoys from Italy, because all the coasts were guarded with great diligence by Pompey's adherents; and because his own fleets, which he had built during the winter, in Sicily, Gaul, and Italy, were detained; sent Lucius Canuleius into Epirus to procure corn; and because these countries were too remote, he fixed granaries in certain places, and regulated the carriage of the corn for the neighbouring states. He likewise gave directions that search should be made for whatever corn was in Lissus, the country of the Parthini, and all the places of strength. The quantity was very small, both from the nature of the land (for the country is rough and mountainous, and the people commonly import what grain they use); and because Pompey had foreseen what would happen, and some days before had plundered the Parthini, and having ravaged and dug up their houses, carried off all the corn, which he collected by means of his horse.
XLIII.—Caesar, on being informed of these transactions, pursued measures suggested by the nature of the country. For round Pompey's camps there were several high and rough hills. These he first of all occupied with guards, and raised strong forts on them. Then drawing a fortification from one fort to another, as the nature of each position allowed, he began to draw a line of circumvallation round Pompey; with these views; as he had but a small quantity of corn, and Pompey was strong in cavalry, that he might furnish his army with corn and other necessaries from all sides with less danger: secondly, to prevent Pompey from foraging, and thereby render his horse ineffectual in the operations of the war; and thirdly, to lessen his reputation, on which he saw he depended greatly, among foreign nations, when a report should have spread throughout the world that he was blockaded by Caesar, and dare not hazard a battle.
XLIV.—Neither was Pompey willing to leave the sea and Dyrrachium, because he had lodged his mat['e]riel there, his weapons, arms, and engines; and supplied his army with corn from it by his ships: nor was he able to put a stop to Caesar's works without hazarding a battle, which at that time he had determined not to do. Nothing was left but to adopt the last resource, namely, to possess himself of as many hills as he could, and cover as great an extent of country as possible with his troops, and divide Caesar's forces as much as possible; and so it happened: for having raised twenty-four forts, and taken in a compass of fifteen miles, he got forage in this space, and within this circuit there were several fields lately sown, in which the cattle might feed in the meantime. And as our men, who had completed their works by drawing lines of communication from one fort to another, were afraid that Pompey's men would sally out from some part, and attack us in the rear; so the enemy were making a continued fortification in a circuit within ours to prevent us from breaking in on any side, or surrounding them on the rear. But they completed their works first; both because they had a greater number of men, and because they had a smaller compass to enclose. When Caesar attempted to gain any place, though Pompey had resolved not to oppose him with his whole force or to come to a general engagement; yet he detached to particular places slingers and archers, with which his army abounded, and several of our men were wounded, and filled with great dread of the arrows; and almost all the soldiers made coats or coverings for themselves of hair cloths, tarpaulins, or raw hides to defend them against the weapons.
XLV.—In seizing the posts, each exerted his utmost power: Caesar, to confine Pompey within as narrow a compass as possible; Pompey, to occupy as many hills as he could in as large a circuit as possible, and several skirmishes were fought in consequence of it. In one of these, when Caesar's ninth legion had gained a certain post, and had begun to fortify it; Pompey possessed himself of a hill near to and opposite the same place, and endeavoured to annoy the men while at work; and as the approach on one side was almost level, he first surrounded it with archers and slingers, and afterwards by detaching a strong party of light infantry, and using his engines, he stopped our works: and it was no easy matter for our men at once to defend themselves, and to proceed with their fortifications. When Caesar perceived that his troops were wounded from all sides, he determined to retreat and give up the post; his retreat was down a precipice, on which account they pushed on with more spirit, and would not allow us to retire, because they imagined that we resigned the place through fear. It is reported that Pompey said that day in triumph to his friends about him, "That he would consent to be accounted a general of no experience, if Caesar's legions effected a retreat without considerable loss from that ground into which they had rashly advanced."
XLVI.—Caesar, being uneasy about the retreat of his soldiers, ordered hurdles to be carried to the further side of the hill, and to be placed opposite to the enemy, and behind them a trench of a moderate breadth to be sunk by his soldiers under shelter of the hurdles: and the ground to be made as difficult as possible. He himself disposed slingers in convenient places to cover our men in their retreat. These things being completed, he ordered his legions to file off. Pompey's men insultingly and boldly pursued and chased us, levelling the hurdles that were thrown up in the front of our works, in order to pass over the trench. Which as soon as Caesar perceived, being afraid that his men would appear not to retreat, but to be repulsed, and that greater loss might be sustained, when his men were almost half way down the hill, he encouraged them by Antonius, who commanded that legion, ordered the signal of battle to be sounded, and a charge to be made on the enemy. The soldiers of the ninth legion suddenly closing their files threw their javelins, and advancing impetuously from the low ground up the steep, drove Pompey's men precipitately before them, and obliged them to turn their backs; but their retreat was greatly impeded by the hurdles that lay in a long line before them, and the pallisadoes which were in their way, and the trenches that were sunk. But our men being contented to retreat without injury, having killed several of the enemy, and lost but five of their own, very quietly retired, and having seized some other hills somewhat on this side of that place, completed their fortifications.
