Through the most marvellous good fortune the landing of the second freight had also been successful.
Junction Of Caesar's Army
Antonius and Caesar were no doubt still some four days' march from each other, separated by Dyrrhachium and the whole army of the enemy; but Antonius happily effected the perilous march round about Dyrrhachium through the passes of the Graba Balkan, and was received by Caesar, who had gone to meet him, on the right bank of the Apsus. Pompeius, after having vainly attempted to prevent the junction of the two armies of the enemy and to force the corps of Antonius to fight by itself, took up a new position at Asparagium on the river Genusus (Skumbi), which flows parallel to the Apsus between the latter and the town of Dyrrhachium, and here remained once more immoveable. Caesar felt himself now strong enough to give battle; but Pompeius declined it. On the other hand Caesar succeeded in deceiving his adversary and throwing himself unawares with his better marching troops, just as at Ilerda, between the enemy's camp and the fortress of Dyrrhachium on which it rested as a basis. The chain of the Graba Balkan, which stretching in a direction from east to west ends on the Adriatic in the narrow tongue of land at Dyrrhachium, sends off--fourteen miles to the east of Dyrrhachium--in a south-westerly direction a lateral branch which likewise turns in the form of a crescent towards the sea, and the main chain and lateral branch of the mountains enclose between themselves a small plain extending round a cliff on the seashore.
Pompeius now took up his camp, and, although Caesar's army kept the land route to Dyrrhachium closed against him, he yet with the aid of his fleet remained constantly in communication with the town and was amply and easily provided from it with everything needful; while among the Caesarians, notwithstanding strong detachments to the country lying behind, and notwithstanding all the exertions of the general to bring about an organized system of conveyance and thereby a regular supply, there was more than scarcity, and flesh, barley, nay even roots had very frequently to take the place of the wheat to which they were accustomed.
Caesar Invests The Camp Of Pompeius
As his phlegmatic opponent persevered in his inaction, Caesar undertook to occupy the circle of heights which enclosed the plain on the shore held by Pompeius, with the view of being able at least to arrest the movements of the superior cavalry of the enemy and to operate with more freedom against Dyrrhachium, and if possible to compel his opponent either to battle or to embarkation. Nearly the half of Caesar's troops was detached to the interior; it seemed almost Quixotic to propose with the rest virtually to besiege an army perhaps twice as strong, concentrated in position, and resting on the sea and the fleet. Yet Caesar's veterans by infinite exertions invested the Pompeian camp with a chain of posts sixteen miles long, and afterwards added, just as before Alesia, to this inner line a second outer one, to protect themselves against attacks from Dyrrhachium and against attempts to turn their position which could so easily be executed with the aid of the fleet. Pompeius attacked more than once portions of these entrenchments with a view to break if possible the enemy's line, but he did not attempt to prevent the investment by a battle; he preferred to construct in his turn a number of entrenchments around his camp, and to connect them with one another by lines. 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.
