In the meantime Pompey assembled a great army; and at sea he was altogether invincible. For he had five hundred ships of war, and the number of his lighter vessels was still greater. As for his land forces, he had seven thousand horse, the flower of Rome and Italy, all men of family, fortune, and courage. His infantry, though numerous, was a mixture of raw, undisciplined soldiers; he therefore exercised them during his stay at Beroea, where he was by no means idle, but went through the exercises of a soldier, as if he had been in the flower of his age. It inspired his troops with new courage, when they saw Pompey the Great, at the age of fifty-eight, going through the whole military discipline, in heavy armor, on foot; and then mounting his horse, drawing his sword with ease when at full speed, and as dexterously sheathing it again. As to the javelin, he threw it not only with great exactness, but with such force that few of the young men could dart it to a greater distance.
Many kings and princes repaired to his camp; and the number of Roman officers who had commanded armies was so great, that it was sufficient to make up a complete senate. Labienus, who had been honored with Caesar's friendship, and served under him in Gaul, now joined Pompey.
Caesar had now made himself master of Pompey's forces in Spain, and though it was not without a battle, he dismissed the officers, and incorporated the troops with his own. After this, he passed the Alps again, and marched through Italy to Brundusium, where he arrived at the time of the winter solstice. There he crossed the sea, and landed at Oricum; from whence he dispatched Vibullius, one of Pompey's friends, whom he had brought prisoner thither, with proposals of a conference between him and Pompey, in which they should agree to disband their armies within three days, renew their friendship, confirm it with solemn oath, and then both return to Italy. Pompey took this overture for another snare, and therefore drew down in haste to the sea, and secured all the forts and places of strength for land forces, as well as all the ports and other commodious stations for shipping; so that there was not a wind that blew, which did not bring him either provisions, or troops, or money. On the other hand, Caesar was reduced to such straits, both by sea and land, that he was under the necessity of seeking a battle. Accordingly, he attacked Pompey's intrenchments, and bade him defiance daily. In most of these attacks and skirmishes he had the advantage; but one day was in danger of losing his whole army. Pompey fought with so much valor, that he put Caesar's whole detachment to flight, after having killed two thousand men upon the spot; but was either unable or afraid to pursue his blow, and enter their camp with them. Caesar said to his friends on this occasion, "This day the victory had been the enemy's had their general known how to conquer."Pompey's troops, elated with this success, were in great haste to come to a decisive battle. Nay, Pompey himself seemed to give in to their opinions by writing to the kings, the generals, and cities, in his interest, in the style of a conqueror. Yet all this while he dreaded the issue of a general action, believing it much better, by length of time, by famine and fatigue, to tire out men who had been ever invincible in arms, and long accustomed to conquer when they fought together. Besides, he knew the infirmities of age had made them unfit for the other operations of war, for long marches and countermarches, for digging trenches and building forts, and that, therefore, they wished for nothing so much as a battle. Pompey, with all these arguments, found it no easy matter to keep his army quiet.
After this last engagement, Caesar was in such want of provisions, that he was forced to decamp, and he took his way through Athamania into Thessaly. This added so much to the high opinion Pompey's soldiers had of themselves, that it was impossible to keep them within bounds. They cried out with one voice, "Caesar is fled." Some called upon the general to pursue; some to pass over into Italy. Others sent their friends and servants to Rome, to engage homes near the forum, for the convenience of soliciting the great offices of state. And not a few went of their own accord to Cornelia, who had been privately lodged in Lesbos, to congratulate her upon the conclusion of the war.
While he thus softly followed the enemy's steps, a complaint was raised against him, and urged with much clamor, that he was not exercising his generalship upon Caesar, but upon the Senate and the whole commonwealth, in order that he might forever keep the command in his hands, and have those for his guards and servants who had a right to govern the world. Domitius Aenobarbus, to increase the odium, always called him Agamemnon, or king of kings.
