As soon as he received through the first fugitives that arrived at Cabira from the field of battle—significantly enough, the beaten generals themselves—the fatal news, earlier even than Lucullus got tidings of the victory, he resolved on an immediate farther retreat. But the resolution taken by the king spread with the rapidity of lightning among those immediately around him; and, when the soldiers saw the confidants of the king packing in all haste, they too were seized with a panic. No one was willing to be the hindmost in decamping; all, high and low, ran pell-mell like startled deer; no authority, not even that of the king, was longer heeded; and the king himself was carried away amidst the wild tumult. Lucullus, perceiving the confusion, made his attack, and the Pontic troops allowed themselves to be massacred almost without offering resistance. Had the legions been able to maintain discipline and to restrain their eagerness for spoil, hardly a man would have escaped them, and the king himself would doubtless have been taken. With difficulty Mithradates escaped along with a few attendants through the mountains to Comana (not far from Tocat and the source of the Iris); from which, however, a Roman corps under Marcus Pompeius soon scared him off and pursued him, till, attended by not more than 2000 cavalry, he crossed the frontier of his kingdom at Talaura in Lesser Armenia. In the empire of the great-king he found a refuge, but nothing more (end of 682). Tigranes, it is true, ordered royal honours to be shown to his fugitive father-in-law; but he did not even invite him to his court, and detained him in the remote border-province to which he had come in a sort of decorous captivity.

Pontus Becomes Roman
Sieges of the Pontic Cities

The Roman troops overran all Pontus and Lesser Armenia, and as far as Trapezus the flat country submitted without resistance to the conqueror. The commanders of the royal treasure-houses also surrendered after more or less delay, and delivered up their stores of money. The king ordered that the women of the royal harem—his sisters, his numerous wives and concubines—as it was not possible to secure their flight, should all be put to death by one of his eunuchs at Pharnacea (Kerasunt). The towns alone offered obstinate resistance. It is true that the few in the interior— Cabira, Amasia, Eupatoria—were soon in the power of the Romans; but the larger maritime towns, Amisus and Sinope in Pontus, Amastris in Paphlagonia, Tius and the Pontic Heraclea in Bithynia, defended themselves with desperation, partly animated by attachment to the king and to their free Hellenic constitution which he had protected, partly overawed by the bands of corsairs whom the king had called to his aid. Sinope and Heraclea even sent forth vessels against the Romans; and the squadron of Sinope seized a Roman flotilla which was bringing corn from the Tauric peninsula for the army of Lucullus. Heraclea did not succumb till after a two years' siege, when the Roman fleet had cut off the city from intercourse with the Greek towns on the Tauric peninsula and treason had broken out in the ranks of the garrison. When Amisus was reduced to extremities, the garrison set fire to the town, and under cover of the flames took to their ships. In Sinope, where the daring pirate-captain Seleucus and the royal eunuch Bacchides conducted the defence, the garrison plundered the houses before it withdrew, and set on fire the ships which it could not take along with it; it is said that, although the greater portion of the defenders were enabled to embark, 8000 corsairs were there put to death by Lucullus. These sieges of towns lasted for two whole years and more after the battle of Cabira (682-684); Lucullus prosecuted them in great part by means of his lieutenants, while he himself regulated the affairs of the province of Asia, which demanded and obtained a thorough reform.

Remarkable, in an historical point of view, as was that obstinate resistance of the Pontic mercantile towns to the victorious Romans, it was of little immediate use; the cause of Mithradates was none the less lost. The great-king had evidently, for the present at least, no intention at all of restoring him to his kingdom. The Roman emigrants in Asia had lost their best men by the destruction of the Aegean fleet; of the survivors not a few, such as the active leaders Lucius Magius and Lucius Fannius, had made their peace with Lucullus; and with the death of Sertorius, who perished in the year of the battle of Cabira, the last hope of the emigrants vanished. Mithradates' own power was totally shattered, and one after another his remaining supports gave way; his squadrons returning from Crete and Spain, to the number of seventy sail, were attacked and destroyed by Triarius at the island of Tenedos; even the governor of the Bosporan kingdom, the king's own son Machares, deserted him, and as independent prince of the Tauric Chersonese concluded on his own behalf peace and friendship with the Romans (684). The king himself, after a not too glorious resistance, was confined in a remote Armenian mountain-stronghold, a fugitive from his kingdom and almost a prisoner of his son-in-law. Although the bands of corsairs might still hold out in Crete, and such as had escaped from Amisus and Sinope might make their way along the hardly- accessible east coast of the Black Sea to the Sanigae and Lazi, the skilful conduct of the war by Lucullus and his judicious moderation, which did not disdain to remedy the just grievances of the provincials and to employ the repentant emigrants as officers in his army, had at a moderate sacrifice delivered Asia Minor from the enemy and annihilated the Pontic kingdom, so that it might be converted from a Roman client-state into a Roman province. A commission of the senate was expected, to settle in concert with the commander-in-chief the new provincial organization.

Beginning of the Armenian War

But the relations with Armenia were not yet settled. Thata declaration of war by the Romans against Tigranes was in itself justified and even demanded, we have already shown. Lucullus, who looked at the state of affairs from a nearer point of view and with a higher spirit than the senatorial college in Rome, perceived clearly the necessity of confining Armenia to the other side of the Tigris and of re-establishing the lost dominion of Rome over the Mediterranean. He showed himself in the conduct of Asiatic affairs no unworthy successor of his instructor and friend Sulla. A Philhellene above most Romans of his time, he was not insensible to the obligation which Rome had come under when taking up the heritage of Alexander—the obligation to be the shield and sword of the Greeks in the east. Personal motives—the wish to earn laurels also beyond the Euphrates, irritation at the fact that the great- king in a letter to him had omitted the title of Imperator—may doubtless have partly influenced Lucullus; but it is unjust to assume paltry and selfish motives for actions, which motives of duty quite suffice to explain. The Roman governing college at any rate—timid, indolent, ill informed, and above all beset by perpetual financial embarrassments—could never be expected, without direct compulsion, to take the initiative in an expedition so vast and costly. About the year 682 the legitimate representatives of the Seleucid dynasty, Antiochus called the Asiatic and his brother, moved by the favourable turn of the Pontic war, had gone to Rome to procure a Roman intervention in Syria, and at the same time a recognition of their hereditary claims on Egypt. If the latter demand might not be granted, there could not, at any rate, be found a more favourable moment or occasion for beginning the war which had long been necessary against Tigranes. But the senate, while it recognized the princes doubtless as the legitimate kings of Syria, could not make up its mind to decree the armed intervention. If the favourable opportunity was to be employed, and Armenia was to be dealt with in earnest, Lucullus had to begin the war, without any proper orders from the senate, at his own hand and his own risk; he found himself, just like Sulla, placed under the necessity of executing what he did in the most manifest interest of the existing government, not with its sanction, but in spite of it. His resolution was facilitated by the relations of Rome towards Armenia, for long wavering in uncertainty between peace and war, which screened in some measure the arbitrariness of his proceedings, and failed not to suggest formal grounds for war. The state of matters in Cappadocia and Syria afforded pretexts enough; and already in the pursuit of the king of Pontus Roman troops had violated the territory of the great-king. As, however, the commission of Lucullus related to the conduct of the war against Mithradates and he wished to connect what he did with that commission, he preferred to send one of his officers, Appius Claudius, to the great-king at Antioch to demand the surrender of Mithradates, which in fact could not but lead to war.

Difficulties to Be Encountered

The resolution was a grave one, especially considering the condition of the Roman army. It was indispensable during the campaign in Armenia to keep the extensive territory of Pontus strongly occupied, for otherwise the army stationed in Armenia might lose its communications with home; and besides it might be easily foreseen that Mithradates would attempt an inroad into his former kingdom. The army, at the head of which Lucullus had ended the Mithradatic war, amounting to about 30,000 men, was obviously inadequate for this double task. Under ordinary circumstances the general would have asked and obtained from his government the despatch of a second army; but as Lucullus wished, and was in some measure compelled, to take up the war over the head of the government, he found himself necessitated to renounce that plan and—although he himself incorporated the captured Thracian mercenaries of the Pontic king with his troops—to carry the war over the Euphrates with not more than two legions, or at most 15,000 men. This was in itself hazardous; but the smallness of the number might be in some degree compensated by the tried valour of the army consisting throughout of veterans. A far worse feature was the temper of the soldiers, to which Lucullus, in his high aristocratic fashion, had given far too little heed. Lucullus was an able general, and—according to the aristocratic standard— an upright and kindly-disposed man, but very far from being a favourite with his soldiers. He was unpopular, as a decided adherent of the oligarchy; unpopular, because he had vigorously checked the monstrous usury of the Roman capitalists in Asia Minor; unpopular, on account of the toils and fatigues which he inflicted on his troops; unpopular, because he demanded strict discipline in his soldiers and prevented as far as possible the pillage of the Greek towns by his men, but withal caused many a waggon and many a camel to be laden with the treasures of the east for himself; unpopular too on account of his manner, which was polished, haughty, Hellenizing, not at all familiar, and inclining, wherever it was possible, to ease and pleasure. There was no trace in him of the charm which weaves a personal bond between the general and the soldier. Moreover, a large portion of his ablest soldiers had every reason to complain of the unmeasured prolongation of their term of service. His two best legions were the same which Flaccus and Fimbria had led in 668 to the east;(14) notwithstanding that shortly after the battle of Cabira they had been promised their discharge well earned by thirteen campaigns, Lucullus now led them beyond the Euphrates to face a new incalculable war—it seemed as though the victors of Cabira were to be treated worse than the vanquished of Cannae.(15) It was in fact more than rash that, with troops so weak and so much out of humour, a general should at his own hand and, strictly speaking, at variance with the constitution, undertake an expedition to a distant and unknown land, full of rapid streams and snow-clad mountains—a land which from the very vastness of its extent rendered any lightly-undertaken attack fraught with danger. The conduct of Lucullus was therefore much and not unreasonably censured in Rome; only, amidst the censure the fact should not have been concealed, that the perversity of the government was the prime occasion of this venturesome project of the general, and, if it did not justify it, rendered it at least excusable.

Lucullus Crosses the Euphrates

The mission of Appius Claudius was designed not only to furnish a diplomatic pretext for the war, but also to induce the princes and cities of Syria especially to take arms against the great-king: in the spring of 685 the formal attack began. During the winter the king of Cappadocia had silently provided vessels for transport; with these the Euphrates was crossed at Melitene, and the further march was directed by way of the Taurus-passes to the Tigris. This too Lucullus crossed in the region of Amida (Diarbekr), and advanced towards the road which connected the second capital Tigranocerta,(16) recently founded on the south frontier of Armenia, with the old metropolis Artaxata. At the former was stationed the great-king, who had shortly before returned from Syria, after having temporarily deferred the prosecution of his plans of conquest on the Mediterranean on account of the embroilment with the Romans. He was just projecting an inroad into Roman Asia from Cilicia and Lycaonia, and was considering whether the Romans would at once evacuate Asia or would previously give him battle, possibly at Ephesus, when the news was brought to him of the advance of Lucullus, which threatened to cut off his communications with Artaxata. He ordered the messenger to be hanged, but the disagreeable reality remained unaltered; so he left the new capital and resorted to the interior of Armenia, in order there to raise a force—which had not yet been done—against the Romans. Meanwhile Mithrobarzanes with the troops actually at his disposal and in concert with the neighbouring Bedouin tribes, who were called out in all haste, was to give employment to the Romans. But the corps of Mithrobarzanes was dispersed by the Roman vanguard, and the Arabs by a detachment under Sextilius; Lucullus gained the road leading from Tigranocerta to Artaxata, and, while on the right bank of the Tigrisa Roman detachment pursued the great-king retreating northwards, Lucullus himself crossed to the left and marched forward to Tigranocerta.
