But when the tents were now taken down, his scouts rode up to him, and told him the enemy would give him battle. With this news he was extremely pleased, and having performed his devotions to the gods, set his army in battle array, dividing them into three bodies. Over the middlemost he placed Domitius Calvinus; Antony commanded the left wing, and he himself the right, being resolved to fight at the head of the tenth legion. But when he saw the enemy's cavalry taking position against him, being struck with their fine appearance and their number, he gave private orders that six cohorts from the rear of the army should come and join him, whom he posted behind the right wing, and instructed them what they should do when the enemy's horse came to charge. On the other side, Pompey commanded the right wing, Domitius the left, and Scipio, Pompey's father-in-law, the centre. The whole weight of the cavalry was collected on the left wing, with the intent that they should outflank the right wing of the enemy, and rout that part where the general himself commanded. For they thought no phalanx of infantry could be solid enough to sustain such a shock, but that they must necessarily be broken and shattered all to pieces upon the onset of so immense a force of cavalry. When they were ready on both sides to give the signal for battle, Pompey commanded his foot, who were in the front, to stand their ground, and without breaking their order, receive, quietly, the enemy's first attack, till they came within javelin's cast. Caesar, in this respect, also, blames Pompey's generalship, as if he had not been aware how the first encounter, when made with an impetus and upon the run, gives weight and force to the strokes, and fires the men's spirits into a flame, which the general concurrence fans to full heat. He himself was just putting the troops into motion and advancing to the action, when he found one of his captains, a trusty and experienced soldier, encouraging his men to exert their utmost. Caesar called him by his name, and said, "What hopes, Caius Crassinius, and what grounds for encouragement?" Crassinius stretched out his hand, and cried in a loud voice, "We shall conquer nobly, Caesar; and I this day will deserve your praises, either alive or dead." So he said, and was the first man to run in upon the enemy, followed by the hundred and twenty soldiers about him, and breaking through the first rank, still pressed on forwards with much slaughter of the enemy, till at last he was struck back by the wound of a sword, which went in at his mouth with such force that it came out at his neck behind.
Whilst the foot was thus sharply engaged in the main battle, on the flank Pompey's horse rode up confidently, and opened their ranks very wide, that they might surround the right wing of Caesar. But before they engaged, Caesar's cohorts rushed out and attacked them, and did not dart their javelins at a distance, nor strike at the thighs and legs, as they usually did in close battle, but aimed at their faces. For thus Caesar had instructed them, in hopes that young gentlemen, who had not known much of battles and wounds, but came wearing their hair long, in the flower of their age and height of their beauty, would be more apprehensive of such blows, and not care for hazarding both a danger at present and a blemish for the future.
And so it proved, for they were so far from bearing the stroke of the javelins, that they could not stand the sight of them, but turned about, and covered their faces to secure them. Once in disorder, presently they turned about to fly; and so most shamefully ruined all. For those who had beat them back at once outflanked the infantry, and falling on their rear, cut them to pieces. Pompey, who commanded the other wing of the army, when he saw his cavalry thus broken and flying, was no longer himself, nor did he now remember that he was Pompey the Great, but, like one whom some god had deprived of his senses, retired to his tent without speaking a word, and there sat to expect the event, till the whole army was routed and the enemy appeared upon the works which were thrown up before the camp, where they closely engaged with his men who were posted there to defend it. Then first he seemed to have recovered his senses, and uttering, it is said, only these words, "What, into the camp too?" he laid aside his general's habit, and putting on such clothes as might best favour his flight, stole off. What fortune he met with afterwards, how he took shelter in Egypt, and was murdered there, we tell you in his Life.
Caesar, when he came to view Pompey's camp, and saw some of his opponents dead upon the ground, others dying, said, with a groan, "This they would have; they brought me to this necessity. I, Caius Caesar, after succeeding in so many wars, had been condemned had Idismissed my army." These words, Pollio says, Caesar spoke in Latin at that time, and that he himself wrote them in Greek; adding, that those who were killed at the taking of the camp were most of them servants; and that not above six thousand soldiers fell. Caesar incorporated most of the foot whom he took prisoners with his own legions, and gave a free pardon to many of the distinguished persons, and amongst the rest to Brutus, who afterwards killed him. He did not immediately appear after the battle was over, which put Caesar, it is said, into great anxiety for him; nor was his pleasure less when he saw him present himself alive.
