Pompey was at once proclaimed Imperator. And Pompey used the name, though the victory had, alas! been gained over his fellow-countrymen. “So great was the effect of all this on the spirits and confidence of the Pompeians, that they thought no more of the carrying on of the war, but only of the victory they had gained.” And then Cæsar throws scorn upon the Pompeians, making his own apology in the same words. “They did not care to remember that the small number of our soldiers was the cause of their triumph, or that the unevenness of the ground and narrowness of the defiles had aught to do with it; or the occupation of our lines, and the panic of our men between their double fortifications; or our army cut into two parts, so that one part could not help the other. Nor did they add to this the fact that our men, pressed as they were, could not engage themselves in a fair conflict, and that they indeed suffered more from their own numbers, and from the narrowness of the ravines, than from the enemy. Nor were the ordinary chances of war brought to mind,—how small matters, such as some unfounded suspicion, a sudden panic, a remembered superstition, may create great misfortune; nor how often the fault of a general, or the mistake of an officer, may bring injury upon an army. But they spread abroad the report of the victory of that day throughout all the world, sending forth letters and tales as though they had conquered solely by their own valour, nor was it possible that there should after this be a reverse of their circumstances.” Such was the affair of Petra, by which the relative position in the world-history of Cæsar and Pompey was very nearly made the reverse of what it is.
Cæsar now acknowledges that he is driven to change the whole plan of his campaign. He addresses a speech to his men, and explains to them that this defeat, like that at Gergovia, may lead to their future success. The victory at Alesia had sprung from the defeat of Gergovia, because the Gauls had been induced to fight; and from the reverses endured within the lines of Petra might come the same fortune;—for surely now the army of Pompey would not fear a battle. Some few officers he punishes and degrades. His own words respecting his army after their defeat are very touching. “So great a grief had come from this disaster upon the whole army, and so strong a desire of repairing its disgrace, that no one now desired the place of tribune or centurion in his legion; and all, by way of self-imposed punishment, subjected themselves to increased toil; and every man burned with a desire to fight. Some from the higher ranks were so stirred by Cæsar’s speech, that they thought that they should stand their ground where they were, and fight where they stood.” But Cæsar was too good a general for that. He moves on towards the south-east, and in retreating gets the better of Pompey, who follows him with only half a heart. After a short while Pompey gives up the pursuit. His father-in-law, Scipio, has brought a great army from the east, and is in Thessaly. As we read this we cannot fail to remember how short a time since it was that Cæsar himself was Pompey’s father-in-law, and that Pompey was Cæsar’s friend because, with too uxorious a love, he clung to Julia, his young wife. Pompey now goes eastward to unite his army to that of Scipio; and Cæsar, making his way also into Thessaly by a more southern route, joins certain forces under his lieutenant Calvinus, who had been watching Scipio, and who barely escaped falling into Pompey’s hands before he could reach Cæsar. But wherever Fortune or Chance could interfere, the Gods were always kind to Cæsar.
Then Cæsar tells us of his treatment of two towns in Thessaly, Gomphi and Metropolis. Unluckily for the poor Gomphians, Cæsar reaches Gomphi first. Now the fame of Pompey’s victory at Petra had been spread abroad; and the Gomphians, who,—to give them their due,—would have been just as willing to favour Cæsar as Pompey, and who only wanted to be on the winning side that they might hold their little own in safety, believed that things were going badly with Cæsar. They therefore shut their gates against Cæsar, and sent off messengers to Pompey. They can hold their town against Cæsar for a little while, but Pompey must come quickly to their aid. Pompey comes by no means quick enough, and the Gomphians’ capacity to hold their own is very short-lived. At about three o’clock in the afternoon Cæsar begins to besiege the town, and before sunset he has taken it, and given it to be sacked by his soldiers. The men of Metropolis were also going to shut their gates, but luckily they hear just in time what had happened at Gomphi,—and open them instead. Whereupon Cæsar showers protection upon Metropolis; and all the other towns of Thessaly, hearing what had been done, learn what Cæsar’s favour means.
Pompey, having joined his army to that of Scipio, shares all his honours with his father-in-law. When we hear this we know that Pompey’s position was not comfortable, and that he was under constraint. He was a man who would share his honour with no one unless driven to do so. And indeed his command at present was not a pleasant one. It was much for a Roman commander to have with him the Roman Senate,—but the senators so placed would be apt to be less obedient than trained soldiers. They even accuse him of keeping them in Thessaly because he likes to lord it over such followers. But they were, nevertheless, all certain that Cæsar was about to be destroyed; and, even in Pompey’s camp, they quarrel over the rewards of victory which they think that they will enjoy at Rome when their oligarchy shall have been re-established by Pompey’s arms.
Before the great day arrives Labienus again appears on the scene; and Cæsar puts into his mouth a speech which he of course intends us to compare with the result of the coming battle. “Do not think, O Pompey, that this is the army which conquered Gaul and Germany,”—where Labienus himself was second in command under Cæsar. “I was present at all those battles, and speak of a thing which I know. A very small part of that army remains. Many have perished,—as a matter of course in so many battles. The autumn pestilence killed many in Italy. Many have gone home. Many have been left on the other shore. Have you not heard from our own friends who remained behind sick, that these cohorts of Cæsar’s were made up at Brindisi?”—made up but the other day, Labienus implies. “This army, indeed, has been renewed from levies in the two Gauls; but all that it had of strength perished in those two battles at Dyrrachium;”—in the contests, that is, within the lines of Petra. Upon this Labienus swears that he will not sleep under canvas again until he sleeps as victor over Cæsar; and Pompey swears the same, and everybody swears. Then they all go away full of the coming victory. We daresay there was a great deal of false confidence; but as for the words which Cæsar puts into the mouth of Labienus, we know well how much cause Cæsar had to dislike Labienus, and we doubt whether they were ever spoken.
At length the battle-field is chosen,—near the town of Pharsalus, on the banks of the river Enipeus in Thessaly. The battle has acquired world-wide fame as that of Pharsalia, which we have been taught to regard as the name of the plain on which it was fought. Neither of these names occur in the Commentary, nor does that of the river; and the actual spot on which the great contest took place seems to be a matter of doubt even now. The ground is Turkish soil,—near to the mountains which separate modern Greece from Turkey, and is not well adapted for the researches of historical travellers. Cæsar had been keeping his men on the march close to Pompey, till Pompey found that he could no longer abstain from fighting. Then came Labienus with his vaunts, and his oath,—and at length the day and the field were chosen. Cæsar at any rate was ready. At this time Cæsar was fifty-two years old, and Pompey was five years his elder.
Cæsar tells us that Pompey had 110 cohorts, or eleven legions. Had the legions been full, Pompey’s army would have contained 66,000 legionaries; but Cæsar states their number at 45,000, or something over two-thirds of the full number. He does not forget to tell us once again that among these eleven were the two legions which he had given up in obedience to the demand of the Senate. Pompey himself, with these two very legions, placed himself on the left away from the river; and there also were all his auxiliaries,—not counted with the legionaries,—slingers, archers, and cavalry. Scipio commanded in the centre with the legions he had brought out of Syria. So Cæsar tells us. “We learn from other sources that Lentulus commanded Pompey’s right wing, lying on the river—and Domitius, whom we remember as trying to hold Marseilles against young Brutus and Trebonius, the left. Cæsar had 80 cohorts, or eight legions, which should have numbered 48,000 men had his legions been full;—but, as he tells us, he led but 22,000 legionaries, so that his ranks were deficient by more than a half. As was his custom, he had his tenth legion to the right, away from the river. The ninth, terribly thinned by what had befallen it within the lines at Petra, joined to the eleventh, lay next the river, forming part of Cæsar’s left wing. Antony commanded the left wing, Domitius Calvinus, whom Cæsar sometimes calls by one name and sometimes by the other, the centre,—and Sulla the right. Cæsar placed himself to the right, with his tenth legion, opposite to Pompey. As far as we can learn, there was but little in the nature of the ground to aid either of them;—and so the fight began.
There is not much complication, and perhaps no great interest, in the account of the actual battle as it is given by Cæsar. Cæsar makes a speech to his army, which was, as we have already learned, and as he tells us now, the accustomed thing to do. No falser speech was ever made by man, if he spoke the words which he himself reports. He first of all reminds them how they themselves are witnesses that he has done his best to insure peace;—and then he calls to their memory certain mock treaties as to peace, in which, when seeking delay, he had pretended to engage himself and his enemy. He had never wasted, he told them, the blood of his soldiers, nor did he desire to deprive the Republic of either army—“alterutro exercitu”—of Pompey’s army or of his own. They were both Roman, and far be it from him to destroy aught belonging to the Republic. We must acknowledge that Cæsar was always chary of Roman life and Roman blood. He would spare it when it could be spared; but he could spill it like water when the spilling of it was necessary to his end. He was very politic; but as for tenderness,—neither he nor any Roman knew what it was.
Then there is a story of one Crastinus, who declares that whether dead or alive he will please Cæsar. He throws the first weapon against the enemy and does please Cæsar. But he has to please by his death, for he is killed in his effort.
Pompey orders that his first rank shall not leave its order to advance, but shall receive the shock of Cæsar’s attack. Cæsar points out to us that he is wrong in this, because the very excitement of a first attack gives increased energy and strength to the men. Cæsar’s legionaries are told to attack, and they rush over the space intervening between the first ranks to do so. But they are so well trained that they pause and catch their breath before they throw their weapons. Then they throw their piles and draw their swords, and the ranks of the two armies are close pitted against each other.
