This set all Pompey's army and officers on fire to hasten and pursue Caesar, whom they concluded to be beaten and flying. But Pompey was afraid to hazard a battle on which so much depended, and being himself provided with all necessaries for any length of time, thought to tire out and waste the vigour of Caesar's army, which could not last long. For the best part of his men, though they had great experience, and showed an irresistible courage in all engagements, yet by their frequent marches, changing their camps, attacking fortifications, and keeping long night-watches, were getting worn out and broken; they being now old, their bodies less fit for labour, and their courage, also, beginning to give way with the failure of their strength. Besides, it was said that an infectious disease, occasioned by their irregular diet, was prevailing in Caesar's army, and what was of greatest moment, he was neither furnished with money nor provisions, so that in a little time he must needs fall of himself.
For these reasons Pompey had no mind to fight him, but was thanked for it by none but Cato, who rejoiced at the prospect of sparing his fellow-citizens. For he, when he saw the dead bodies of those who had fallen in the last battle on Caesar's side, to the number of a thousand, turned away, covered his face, and shed tears. But every one else upbraided Pompey for being reluctant to fight, and tried to goad him on by such nicknames as Agamemnon, and king of kings, as if he were in no hurry to lay down his sovereign authority, but was pleased to see so many commanders attending on him, and paying their attendance at his tent. Favonius, who affected Cato's free way of speaking his mind, complained bitterly that they should eat no figs even this year at Tusculum, because of Pompey's love of command.
Afranius, who was lately returned out of Spain, and, on account of his ill success there, laboured under the suspicion of having been bribed to betray the army, asked why they did not fight this purchaser of provinces. Pompey was driven, against his own will, by this kind of language, into offering battle, and proceeded to follow Caesar. Caesar had found great difficulties in his march, for no country would supply him with provisions, his reputation being very much fallen since his late defeat. But after he took Gomphi, a town of Thessaly, he not only found provisions for his army, but physic too. For there they met with plenty of wine, which they took very freely, and heated with this, sporting and revelling on their march in bacchanalian fashion, they shook off the disease, and their whole constitution was relieved and changed into another habit.
When the two armies were come into Pharsalia, and both encamped there, Pompey's thoughts ran the same way as they had done before, against fighting, and the more because of some unlucky presages, and a vision he had in a dream. But those who were about him were so confident of success, that Domitius, and Spinther, and Scipio, as if they had already conquered, quarrelled which should succeed Caesar in the pontificate. And many sent to Rome to take houses fit to accommodate consuls and praetors, as being sure of entering upon those offices as soon as the battle was over. The cavalry especially were obstinate for fighting, being splendidly armed and bravely mounted, and valuing themselves upon the fine horses they kept, and upon their own handsome persons; as also upon the advantage of their numbers, for they were five thousand against one thousand of Caesar's.
Nor were the numbers of the infantry less disproportionate, there being forty-five thousand of Pompey's against twenty-two thousand of the enemy.
Caesar, collecting his soldiers together, told them that Corfinius was coming up to them with two legions, and that fifteen cohorts more under Calenus were posted at and Athens; he then asked him whether they would stay till these joined them, or would hazard the battle by themselves. They all cried out to him not to wait, but on the contrary to do whatever he could to bring about an engagement as soon as possible. When he sacrificed to the gods for the lustration of his army, upon the death of the first victim, the augur told him, within three days he should come to a decisive action. Caesar asked him whether he saw anything in the entrails which promised a happy event. "That," said the priest, "you can best answer yourself; for the gods signify a great alteration from the present posture of affairs.
If, therefore, you think yourself well off now, expect worse fortune; if unhappy, hope for better." The night before the battle, as he walked the rounds about midnight, there was a light seen in the heavens, very bright and flaming, which seemed to pass over Caesar's camp and fall into Pompey's. And when Caesar's soldiers came to relieve the watch in the morning, they perceived a panic disorder among the enemies. However, he did not expect to fight that day, but set about raising his camp with the intention of marching towards Scotussa.
