Appian of Alexandria Civil Wars 2.11.75

[75] Nevertheless, after he had thus spoken Caesar detailed 2000 of his oldest men to guard the tents. The rest, as they passed out, demolished their fortification in the profoundest silence and filled up the ditch with the debris. When Pompey saw this, although some of his friends thought that it was a preparation for flight, he knew it was an exhibition of daring and groaned in spirit, that although they had with them famine, the most appropriate cure for such wild beasts, he must now meet these creatures in a hand-to-hand contest. But there was no drawing back now, his affairs being on the razor’s edge. ¹ Wherefore, leaving 4000 of his Italian troops to guard his camp, Pompey drew up the remainder between the city of Pharsalus and the river Enipeus opposite the place where Caesar was marshalling his forces. Each of them ranged his Italians in front, divided into three lines with a moderate space between them, and placed his cavalry on the wings of each division. Archers and slingers were mingled among all. Thus were the Italian troops disposed, on which each commander placed his chief reliance. The allied forces were marshalled by themselves rather for show than for use. There was great clamor and confusion of tongues among Pompey’s auxiliaries. Pompey stationed the Macedonians, Peloponnesians, Bœotians, and Athenians near the Italian legions, as he approved of their good order and quiet behavior. The rest, as Caesar had anticipated, he ordered to lie in wait by tribes outside of the line of battle, and when the engagement should become close to surround the enemy, to pursue, to do what damage they could, and to plunder Caesar’s camp, which was without defences.
