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.
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.
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 this 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.
The day was thus lost and many an able soldier had fallen, but the army was still substantially intact, and the situation of Pompeius was far less perilous than that of Caesar after the defeat of Dyrrhachium. But while
