It was not indeed very dark; for the moon, though near her setting, gave light enough to distinguish objects. But it was a great disadvantage to the king's troops, that the moon was so low, and on the backs of the Romans; because she projected their shadows so far before them, that the enemy could form no just estimate of the distances, but thinking them at hand, threw their javelins before they could do the least execution.
The Romans, perceiving their mistake, advanced to the charge with all the alarm of voices. The enemy were in such a consternation, that they made not the least stand, and, in their flight, vast numbers were slain. They lost above 10,000 men, and their camp was taken. As for Mithridates, he broke through the Romans with 800horses, in the beginning of the engagement. That corps, however, did not follow him far before they dispersed, and left him with only three of his people.
The pursuit of Mithridates was attended with great difficulties;for he concealed himself among the nations settled about the Bosphorus and the Palus Maeotis. Besides, news was brought to Pompey that the Albanians had revolted, and taken up arms again.
The desire of revenge determined him to march back, and chastise them. But it was with infinite trouble and danger that he passed the Cyrnus again, the barbarians having fenced it on their side with palisades all along the banks. And when he was over, he had a large country to traverse, which afforded no water. This last difficulty he provided against by filling 10,000 bottles; and pursuing his march, he found the enemy drawn up on the banks of the river Abas, to the number of 60,000 foot and 12,000 horse, but many of them ill-armed, and provided with nothing of the defensive kind but skins of beasts.
They were commanded by the king's brother, named Cosis; who, at the beginning of the battle, singled out Pompey, and rushing in upon him, struck his javelin into the joints of his breastplate.
Pompey in return run him through with his spear, and laid him dead on the spot. It is said that the Amazons came to the assistance of the barbarians from the mountains near the river Thermodon, and fought in this battle. The Romans, among the plunder of the field, did, indeed, meet with bucklers in the form of a half-moon, and such buskins as the Amazons wore; but there was not the body of a woman found among the dead. They inhabit that part of Mount Caucasus which stretches toward the Hyrcanian Sea, and are not next neighbors to the Albanians; for Gelae and Leges lie between;but they meet that people, and spend two months with them every year on the banks of the Thermodon; after which they retire to their own country.
Pompey had advanced near to Petra, and encamped, and was taking some exercise on horseback without the trenches, when messengers arrived from Pontus; and it was plain they brought good news, because the points of their spears were crowned with laurel. The soldiers seeing this, gathered about Pompey, who was inclined to finish his exercise before he opened the packet; but they were so earnest in their entreaties, that they prevailed upon him to alight and take it. He entered the camp with it in his hand; and as there was no tribunal ready, and the soldiers were too impatient to raise one of turf, which the common method, they piled a number of pack-saddles one upon the other, upon which Pompey mounted, and gave them this information: "Mithridates is dead. He killed himself upon the revolt of his son Pharnaces. And Pharnaces has seized all that belonged to his father; which he declares he has done for himself and Romans."At this news the army, as might be expected, gave a loose rein to their joy, which they expressed in sacrifices to the gods, and in reciprocal entertainments, as if 10,000 of their enemies had been slain in Mithridates. Pompey having thus brought the campaign and the whole war to a conclusion so happy, and so far beyond his hopes, immediately quitted Arabia, traverses the provinces between that and Galatia with great rapidity, and soon arrived at Amisus.
There he found many presents from Pharnaces, and several corpses of the royal family, among which was that of Mithridates. As for Pompey, he would not see the body, but to propitiate the avenging Nemesis, sent it to Sinope. However, he looked upon and admired the magnificence of his habit, and the size and beauty of his arms. The scabbard of his sword cost four hundred talents, and the diadem was of most exquisite workmanship.
Pompey having thoroughly settled the affairs of Asia, hoped to return to Italy the greatest and happiest of men.
People talked variously at Rome concerning his intentions. Many disturbed themselves at the thought that he would march with his army immediately to Rome and make himself sole and absolute master there. Crassus took his children and money, and withdrew; whether it was that he had some real apprehensions, or rather that he chose to countenance the calumny, and add force to the sting of envy; the latter seems the more probable. But Pompey had no sooner set foot in Italy, than he called an assembly of his soldiers, and, after a kind and suitable address, ordered them to disperse in their respective cities, and attend to their own affairs till his triumph, on which occasion they were to repair to him again.
