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.
