Caesar

But just as the tents had been struck, his scouts rode up to him with tidings that the enemy were coming down into the plain for battle. At this he was overjoyed, and after prayers and vows to the gods, drew up his legionaries in three divisions. Over the centre he put Domitius Calvinus, while of the wings Antony had one and he himself the right, where he intended to fight with the tenth legion.

But seeing that the enemy’s cavalry were arraying themselves over against this point, and fearing their brilliant appearance and their numbers, he ordered six cohorts from the furthermost lines to come round to him unobserved, and stationed them behind his right wing, teaching them what they were to do when the enemy’s horsemen attacked. Pompey had one of his wings himself and Domitius the left, while Scipio, Pompey’s father-in-law, commanded the centre.

But his horsemen all crowded to the left wing, intending to encircle the enemy’s right and make a complete rout about the commander himself; for they thought that no legionary array, however deep, could resist them, but that when so many horsemen made an onset together the enemy would be utterly broken and crushed.[*](Cf. the Pompey, lxix. 1-3.)
