  Both sides exerted themselves to push forward their trenches as far as possible, and the earthworks advanced but slowly amidst constant conflicts. At the same time skirmishing went on on the opposite side of Caesar's camp with the garrison of Dyrrhachium; Caesar hoped to get the fortress into his power by means of an understanding with some of its inmates, but was prevented by the enemy's fleet. There was incessant fighting at very different points - on one of the hottest days at six places simultaneously - and, as a rule, the tried valour of the Caesarians had the advantage in these skirmishes; once, for instance, a single cohort maintained itself in its entrenchments against four legions for several hours, till support came up. No prominent success was attained on either side; yet the effects of the investment came by degrees to be oppressively felt by the Pompeians. The stopping of the rivulets flowing from the heights into the plain compelled them to be content with scanty and bad well-water. Still more severely felt was the want of fodder for the beasts of burden and the horses, which the fleet was unable adequately to remedy; numbers of them died, and it was of but little avail that the horses were conveyed by the fleet to Dyrrhachium, because there also they did not find sufficient fodder.

  Caesar's Lines Broken - Caesar Once More Defeated

  Pompeius could not much longer delay to free himself from his disagreeable position by a blow struck against the enemy. He was informed by Celtic deserters that the enemy had neglected to secure the beach between his two chains of entrenchments 600 feet distant from each other by a cross-wall, and on this he formed his plan. While he caused the inner line of Caesar's entrenchments to be attacked by the legions from the camp, and the outer line by the light troops placed in vessels and landed beyond the enemy's entrenchments, a third division landed in the space left between the two lines and attacked in the rear their already sufficiently occupied defenders.

  The entrenchment next to the sea was taken, and the garrison fled in wild confusion; with difficulty the commander of the next trench Marcus Antonius succeeded in maintaining it and in setting a limit for the moment to the advance of the Pompeians; but; apart from the considerable loss, the outermost entrenchment along the sea remained in the hands of the Pompeians and the lin was broken through. Caesar the more eagerly seized the opportunity, which soon after presented itself, of attacking a Pompeian legion, which had incautiously become isolated, with the bulk of his infantry. But the attacked offered valiant resistance, and, as the ground on which the fight took place had been several times employed for the encampment of larger and lesser divisions and was intersected in various directions by mounds and ditches, Caesar's right wing along with the cavalry entirely missed its way; instead of supporting the left in attacking the Pompeian legion, it got into a narrow trench that led from one of the old camps towards the river. So Pompeius, who came up in all haste with five legions to the aid of his troops, found the two wings of the enemy separated from each other, and one of them in an utterly forlorn position. When the Caesarians saw him advance, a panic seized them; the whole plunged into disorderly flight; and, if the matter ended with the loss of 1000 of the best soldiers and Caesar's army did not sustain a complete defeat, this was due simply to the circumstance that Pompeius also could not freely develop his force on the broken ground, and to the further fact that, fearing a stratagem, he at first held back his troops.

  Consequences of Caesar's Defeats

  But, even as it was, these days were fraught with mischief. Not only had Caesar endured the most serious losses and forfeited at a blow his entrenchments, the result of four months of gigantic labour; he was by the recent engagements thrown back again exactly to the point from which he had set out. From the sea he was more completely driven than ever, since Pompeius' elder son Gnaeus had by a bold attack partly burnt, partly carried off, Caesar's few ships of war lying in the port of Oricum, and had soon afterwards also set fire to the transport fleet that was left behind in Lissus; all possibility of bringing up fresh reinforcements to Caesar by sea from Brundisium was thus lost. The numerous Pompeian cavalry, now released from their confinement, poured themselves over the adjacent country and threatened to render the provisioning of Caesar's army, which had always been difficult, utterly impossible.

  Caesar's daring enterprise of carrying on offensive operations without ships against an enemy in command of the sea and resting on his fleet had totally failed. On what had hitherto been the theatre of war he found himself in presence of an impregnable defensive position, and unable to strike a serious blow either against Dyrrhachium or against the hostile army; on the other hand it depended now solely on Pompeius whether he should proceed to attack under the most favourable circumstances an antagonist already in grave danger as to his means of subsistence. The war had arrived at a crisis. Hitherto Pompeius had, to all appearance, played the game of war without special plan, and only adjusted his defence according to the exigencies of each attack; and this was not to be censured, for the protraction of the war gave him opportunity of making his recruits capable of fighting, of bringing up his reserves, and of bringing more fully into play the superiority of his fleet in the Adriatic. Caesar was beaten not merely in tactics but also in strategy. This defeat had not, it is true, that effect which Pompeius not without reason expected; the eminent soldierly energy of Caesar's veterans did not allow matters to come to an immediate and total breaking up of the army by hunger and mutiny. But yet it seemed as if it depended solely on his opponent by judiciously following up his victory to reap its full fruits.

  War Prospects of Pompeius - Scipio and Calvinus

  It was for Pompeius to assume the aggressive; and he was resolved to do so. Three different ways of rendering his victory fruitful presented themselves to him. The first and simplest was not to desist from assailing the vanquished army, and, if it departed, to pursue it. Secondly, Pompeius might leave Caesar himself and his best troops in Greece, and might cross in person, as he had long been making preparations for doing, with the main army to Italy, where the feeling was decidedly antimonarchical and the forces of Caesar, after the despatch of the best troops and their brave and trustworthy commandant to the Greek army, would not be of very much moment. Lastly, the victor might turn inland, effect a junction with the legions of Metellus Scipio, and attempt to capture the troops of Caesar stationed in the interior.

  The latter forsooth had, immediately after the arrival of the second freight from Italy, on the one hand despatched strong detachments to Aetolia and Thessaly to procure means of subsistence for his army, and on the other had ordered a corps of two legions under Gnaeus Domitius Calvinus to advance on the Egnatian highway towards Macedonia, with the view of intercepting and if possible defeating in detail the corps of Scipio advancing on the same road from Thessalonica. Calvinus and Scipio had already approached within a few miles of each other, when Scipio suddenly turned southward and, rapidly crossing the Haliacmon (Inje Karasu) and leaving his baggage there under Marcus Favonius, penetrated into Thessaly, in order to attack with superior force Caesar's legion of recruits employed in the reduction of the country under Lucius Cassius Longinus.

  But Longinus retired over the mountains towards Ambracia to join the detachment under Gnaeus Calvisius Sabinus sent by Caesar to Aetolia, and Scipio could only cause him to be pursued by his Thracian cavalry, for Calvinus threatened his reserve left behind under Favonius on the Haliacmon with the same fate which he had himself destined for Longinus. So Calvinus and Scipio met again on the Haliacmon, and encamped there for a considerable time opposite to each other.

  Caesar's Retreat from Dyrrachium to Thessaly

  Pompeius might choose among these plans; no choice was left to Caesar. After that unfortunate engagement he entered on his retreat to Apollonia. Pompeius followed. The march from Dyrrhachium to Apollonia along a difficult road crossed by several rivers was no easy task for a defeated army pursued by the enemy; but the dexterous leadership of their general and the indestructible marching energy of the soldiers compelled Pompeius after fou
r days' pursuit to suspend it as useless.

  He had now to decide between the Italian expedition and the march into the interior. However advisable and attractive the former might seem, and though various voices were raised in its favour, he preferred not to abandon the corps of Scipio, the more especially as he hoped by this march to get the corps of Calvinus into his hands. Calvinus lay at the moment on the Egnatian road at Heraclea Lyncestis, between Pompeius and Scipio, and, after Caesar had retreated to Apollonia, farther distant from the latter than from the great army of Pompeius; without knowledge, moreover, of the events at Dyrrhachium and of his hazardous position, since after the successes achieved at Dyrrhachium the whole country inclined to Pompeius and the messengers of Caesar were everywhere seized. It was not till the enemy's main force had approached within a few hours of him that Calvinus learned from the accounts of the enemy's advanced posts themselves the state of things. A quick departure in a southerly direction towards Thessaly withdrew him at the last moment from imminent destruction; Pompeius had to content himself with having liberated Scipio from his position of peril. Caesar had meanwhile arrived unmolested at Apollonia. Immediately after the disaster of Dyrrhachium he had resolved if possible to transfer the struggle from the coast away into the interior, with the view of getting beyond the reach of the enemy's fleet - the ultimate cause of the failure of his previous exertions. The march to Apollonia had only been intended to place his wounded in safety and to pay his soldiers there, where his depots were stationed; as soon as this was done, he set out for Thessaly, leaving behind garrisons in Apollonia, Oricum, and Lissus. The corps of Calvinus had also put itself in motion towards Thessaly; and Caesar could effect a junction with the reinforcements coming up from Italy, this time by the land-route through Illyria - two legions under Quintus Cornificius - still more easily in Thessaly than in Epirus. Ascending by difficult paths in the valley of the Aous and crossing the mountain-chain which separates Epirus from Thessaly, he arrived at the Peneius; Calvinus was likewise directed thither, and the junction of the two armies was thus accomplished by the shortest route and that which was least exposed to the enemy.

  It took place at Aeginium not far from the source of the Peneius. The first Thessalian town before which the now united army appeared, Gomphi, closed its gates against it; it was quickly stormed and given up to pillage, and the other towns of Thessaly terrified by this example submitted, so soon as Caesar's legions merely appeared before the walls. Amidst these marches and conflicts, and with the help of the supplies - albeit not too ample - which the region on the Peneius afforded, the traces and recollections of the calamitous days through which they had passed gradually vanished.

  The victories of Dyrrhachium had thus borne not much immediate fruit for the victors. Pompeius with his unwieldy army and his numerous cavalry had not been able to follow his versatile enemy into the mountains; Caesar like Calvinus had escaped from pursuit, and the two stood united and in full security in Thessaly.

  Perhaps it would have been the best course, if Pompeius had now without delay embarked with his main force for Italy, where success was scarcely doubtful. But in the meantime only a division of the fleet departed for Sicily and Italy. In the camp of the coalition the contest with Caesar was looked on as so completely decided by the battles of Dyrrhachium that it only remained to reap the fruits of victory, in other words, to seek out and capture the defeated army.

  Their former over-cautious reserve was succeeded by an arrogance still less justified by the circumstances; they gave no heed to the facts, that they had, strictly speaking, failed in the pursuit, that they had to hold themselves in readiness to encounter a completely refreshed and reorganized army in Thessaly, and that there was no small risk in moving away from the sea, renouncing the support of the fleet, and following their antagonist to the battlefield chosen by himself. They were simply resolved at any price to fight with Caesar, and therefore to get at him as soon as possible and by the most convenient way. Cato took up the command in Dyrrhachium, where a garrison was left behind of eighteen cohorts, and in Corcyra, where 300 ships of war were left; Pompeius and Scipio proceeded - the former, apparently, following the Egnatian way as far as Pella and then striking into the great road to the south, the latter from the Haliacmon through the passes of Olympus - to the lower Peneius and met at Larisa.

  The Armies at Pharsalus

  Caesar lay to the south of Larisa in the plain - which extends between the hill-country of Cynoscephalae and the chain of Othrys and is intersected by a tributary of the Peneius, the Enipeus - on the left bank of the latter stream near the town of Pharsalus; Pompeius pitched his camp opposite to him on the right bank of the Enipeus along the slope of the heights of Cynoscephalae[30]. The entire army of Pompeius was assembled; Caesar on the other hand still expected the corps of nearly two legions formerly detached to Aetolia and Thessaly, now stationed under Quintus Fufius Calenus in Greece, and the two legions of Cornificius which were sent after him by the land-route from Italy and had already arrived in Illyria. The army of Pompeius, numbering eleven legions or 47,000 men and 7000 horse, was more than double that of Caesar in infantry, and seven times as numerous in cavalry; fatigue and conflicts had so decimated Caesar's troops, that his eight legions did not number more than 22,000 men under arms, consequently not nearly the half of their normal amount. The victorious army of Pompeius provided with a countless cavalry and good magazines had provisions in abundance, while the troops of Caesar had difficulty in keeping themselves alive and only hoped for better supplies from the corn-harvest not far distant. The Pompeian soldiers, who had learned in the last campaign to know war and trust their leader, were in the best of humour. All military reasons on the side of Pompeius favoured the view, that the decisive battle should not be long delayed, seeing that they now confronted Caesar in Thessaly; and the emigrant impatience of the many genteel officers and others accompanying the army doubtless had more weight than even such reasons in the council of war. Since the events of Dyrrhachium these lords regarded the triumph of their party as an ascertained fact; already there was eager strife as to the filling up of Caesar's supreme pontificate, and instructions were sent to Rome to hire houses at the Forum for the next elections. When Pompeius hesitated on his part to cross the rivulet which separated the two armies, and which Caesar with his much weaker army did not venture to pass, this excited great indignation; Pompeius, it was alleged, only delayed the battle in order to rule somewhat longer over so many consulars and praetorians and to perpetuate his part of Agamemnon. Pompeius yielded; and Caesar, who under the impression that matters would not come to a battle, had just projected a mode of turning the enemy's army and for that purpose was on the point of setting out towards Scotussa, likewise arrayed his legions for battle, when he saw the Pompeians preparing to offer it to him on his bank.

  The Battle

  Thus the battle of Pharsalus was fought on the 9th August 706, almost on the same field where a hundred and fifty years before the Romans had laid the foundation of their dominion in the east[31]. Pompeius rested his right wing on the Enipeus; Caesar opposite to him rested his left on the broken ground stretching in front of the Enipeus; the two other wings were stationed out in the plain, covered in each case by the cavalry and the light troops.

  The intention of Pompeius was to keep his infantry on the defensive, but with his cavalry to scatter the weak band of horsemen which, mixed after the German fashion with light infantry, confronted him, and then to take Caesar's right wing in rear. His infantry courageously sustained the first charge of that of the enemy, and the engagement there came to a stand. Labienus likewise dispersed the enemy's cavalry after a brave but short resistance, and deployed his force to the left with the view of turning the infantry. But Caesar, foreseeing the defeat of his cavalry, had stationed behind it on the threatened flank of his right wing some 2000 of his best legionaries. As the enemy's horsemen, driving those of Caesar before them, galloped along and around the line, they suddenly came upon thi
s select corps advancing intrepidly against them and, rapidly thrown into confusion by the unexpected and unusual infantry attack[32], they galloped at full speed from the field of battle. The victorious legionaries cut to pieces the enemy's archers now unprotected, then rushed at the left wing of the enemy, and began now on their part to turn it. At the same time Caesar's third division hitherto reserved advanced along the whole line to the attack. The unexpected defeat of the best arm of the Pompeian army, as it raised the courage of their opponents, broke that of the army and above all that of the general. When Pompeius, who from the outset did not trust his infantry, saw the horsemen gallop off, he rode back at once from the field of battle to the camp, without even awaiting the issue of the general attack ordered by Caesar. His legions began to waver and soon to retire over the brook into the camp, which was not accomplished without severe loss.
