There was no lack of stores; 2,000,000 medimni of grain lay in the royal granaries. The fleet and the men were numerous and well exercised, particularly the Bastarnian mercenaries, a select corps which was a match even for Italian legionaries. On this occasion also it was the king who took the offensive. A corps under Diophantus advanced into Cappadocia, to occupy the fortresses there and to close the way to the kingdom of Pontus against the Romans; the leader sent by Sertorius, the propraetor Marcus Marius, went in company with the Pontic officer Eumachus to Phrygia, with a view to rouse the Roman province and the Taurus mountains to revolt; the main army, above 100,000 men with 16,000 cavalry and 100 scythe-chariots, led by Taxiles and Hermocrates under the personal superintendence of the king, and the war-fleet of 400 sail commanded by Aristonicus, moved along the north coast of Asia Minor to occupy Paphlagonia and Bithynia.
Roman Preparations
On the Roman side there was selected for the conduct of the war in the first rank the consul of 680, Lucius Lucullus, who as governor of Asia and Cilicia was placed at the head of the four legions stationed in Asia Minor and of a fifth brought by him from Italy, and was directed to penetrate with this army, amounting to 30,000 infantry and 1600 cavalry, through Phrygia into the kingdom of Pontus. His colleague Marcus Cotta proceeded with the fleet and another Roman corps to the Propontis, to cover Asia and Bithynia. Lastly, a general arming of the coasts and particularly of the Thracian coast more immediately threatened by the Pontic fleet, was enjoined; and the task of clearing all the seas and coasts from the pirates and their Pontic allies was, by extraordinary decree, entrusted to a single magistrate, the choice falling on the praetor Marcus Antonius, the son of the man who thirty years before had first chastised the Cilician corsairs[12]. Moreover, the senate placed at the disposal of Lucullus a sum of 72,000,000 sesterces (700,000 pounds), in order to build a fleet; which, however, Lucullus declined. From all this we see that the Roman government recognized the root of the evil in the neglect of their marine, and showed earnestness in the matter at least so far as their decrees reached.
Beginning of the War
Thus the war began in 680 at all points. It was a misfortune for Mithradates, that at the very moment of his declaring war the Sertorian struggle reached its crisis, by which one of his principal hopes was from the outset destroyed, and the Roman government was enabled to apply its whole power to the maritime and Asiatic contest. In Asia Minor on the other hand Mithradates reaped the advantages of the offensive, and of the great distance of the Romans from the immediate seat of war. A considerable number of cities in Asia Minor opened their gates to the Sertorian propraetor who was placed at the head of the Roman province, and they massacred, as in 666, the Roman families settled among them: the Pisidians, Isaurians, and Cilicians took up arms against Rome. The Romans for the moment had no troops at the points threatened. Individual energetic men attempted no doubt at their own hand to check this mutiny of the provincials; thus on receiving accounts of these events the young Gaius Caesar left Rhodes where he was staying on account of his studies, and with a hastily-collected band opposed himself to the insurgents; but not much could be effected by such volunteer corps. Had not Deiotarus, the brave tetrarch of the Tolistobogii - a Celtic tribe settled around Pessinus - embraced the side of the Romans and fought with success against the Pontic generals, Lucullus would have had to begin with recapturing the interior of the Roman province from the enemy. But even as it was, he lost in pacifying the province and driving back the enemy precious time, for which the slight successes achieved by his cavalry were far from affording compensation. Still more unfavourable than in Phrygia was the aspect of things for the Romans on the north coast of Asia Minor. Here the great Pontic army and the fleet had completely mastered Bithynia, and compelled the Roman consul Cotta to take shelter with his far from numerous force and his ships within the walls and port of Chalcedon, where Mithradates kept them blockaded.
The Romans Defeated at Chalcedon
This blockade, however, was so far a favourable event for the Romans, as, if Cotta detained the Pontic army before Chalcedon and Lucullus proceeded also thither, the whole Roman forces might unite at Chalcedon and compel the decision of arms there rather than in the distant and impassable region of Pontus. Lucullus did take the route for Chalcedon; but Cotta, with the view of executing a great feat at his own hand before the arrival of his colleague, ordered his admiral Publius Rutilius Nudus to make a sally, which not only ended in a bloody defeat of the Romans, but also enabled the Pontic force to attack the harbour, to break the chain which closed it, and to burn all the Roman vessels of war which were there, nearly seventy in number. On the news of these misfortunes reaching Lucullus at the river Sangarius, he accelerated his march to the great discontent of his soldiers, in whose opinion Cotta was of no moment, and who would far rather have plundered an undefended country than have taught their comrades to conquer. His arrival made up in part for the misfortunes sustained: the king raised the siege of Chalcedon, but did not retreat to Pontus; he went southward into the old Roman province, where he spread his army along the Propontis and the Hellespont, occupied Lampsacus, and began to besiege the large and wealthy town of Cyzicus. He thus entangled himself more and more deeply in the blind alley which he had chosen to enter, instead of - which alone promised success for him - bringing the wide distances into play against the Romans.
Mithradates Besieges Cyzicus
In few places had the old Hellenic adroitness and aptitude preserved themselves so pure as in Cyzicus; its citizens, although they had suffered great loss of ships and men in the unfortunate double battle of Chalcedon, made the most resolute resistance. Cyzicus lay on an island directly opposite the mainland and connected with it by a bridge. The besiegers possessed themselves not only of the line of heights on the mainland terminating at the bridge and of the suburb situated there, but also of the celebrated Dindymene heights on the island itself; and alike on the mainland and on the island the Greek engineers put forth all their art to pave the way for an assault. But the breach which they at length made was closed again during the night by the besieged, and the exertions of the royal army remained as fruitless as did the barbarous threat of the king to put to death the captured Cyzicenes before the walls, if the citizens still refused to surrender. The Cyzicenes continued the defence with courage and success; they fell little short of capturing the king himself in the course of the siege.
Destruction of the Pontic Army
Meanwhile Lucullus had possessed himself of a very strong position in rear of the Pontic army, which, although not permitting him directly to relieve the hard-pressed city, gave him the means of cutting off all supplies by land from the enemy. Thus the enormous army of Mithradates, estimated with the camp-followers at 300,000 persons, was not in a position either to fight or to march, firmly wedged in between the impregnable city and the immoveable Roman army, and dependent for all its supplies solely on the sea, which fortunately for the Pontic troops was exclusively commanded by their fleet. But the bad season set in; a storm destroyed a great part of the siege-works; the scarcity of provisions and above all of fodder for the horses began to become intolerable. The beasts of burden and the baggage were sent off under convoy of the greater portion of the Pontic cavalry, with orders to steal away or break through at any cost; but at the river Rhyndacus, to the east of Cyzicus, Lucullus overtook them and cut to pieces the whole body. Another division of cavalry under Metrophanes and Lucius Fannius was obliged, after wandering long in the west of Asia Minor, to return to the camp before Cyzicus. Famine and disease made fearful ravages in the Pontic ranks. When spring came on (681), the besieged redoubled their exertions and took the trenches constructed on Dindymon: nothing remained for the king but to raise the siege and with the aid of his fleet to save what he could.
He went in person with the fleet to the Hellespont, but suffered considerable loss partly at its departure, partly through storms on the voyage. The land army under Hermaeus and Marius
likewise set out thither, with the view of embarking at Lampsacus under the protection of its walls. They left behind their baggage as well as the sick and wounded, who were all put to death by the exasperated Cyzicenes. Lucullus inflicted on them very considerable loss by the way at the passage of the rivers Aesepus and Granicus; but they attained their object. The Pontic ships carried off the remains of the great army and the citizens of Lampsacus themselves beyond the reach of the Romans.
Maritime War - Mithradates Driven Back to Pontus
The consistent and discreet conduct of the war by Lucullus had not only repaired the errors of his colleague, but had also destroyed without a pitched battle the flower of the enemy's army - it was said 200,000 soldiers. Had he still possessed the fleet which was burnt in the harbour of Chalcedon, he would have annihilated the whole army of his opponent. As it was, the work of destruction continued incomplete; and while he was obliged to remain passive, the Pontic fleet notwithstanding the disaster of Cyzicus took its station in the Propontis, Perinthus and Byzantium were blockaded by it on the European coast and Priapus pillaged on the Asiatic, and the headquarters of the king were established in the Bithynian port of Nicomedia. In fact a select squadron of fifty sail, which carried 10,000 select troops including Marcus Marius and the flower of the Roman emigrants, sailed forth even into the Aegean; the report went that it was destined to effect a landing in Italy and there rekindle the civil war. But the ships, which Lucullus after the disaster off Chalcedon had demanded from the Asiatic communities, began to appear, and a squadron ran forth in pursuit of the enemy's fleet which had gone into the Aegean. Lucullus himself, experienced as an admiral[13], took the command. Thirteen quinqueremes of the enemy on their voyage to Lemnos, under Isidorus, were assailed and sunk off the Achaean harbour in the waters between the Trojan coast and the island of Tenedos. At the small island of Neae, between Lemnos and Scyros, at which little-frequented point the Pontic flotilla of thirty-two sail lay drawn up on the shore, Lucullus found it, immediately attacked the ships and the crews scattered over the island, and possessed himself of the whole squadron. Here Marcus Marius and the ablest of the Roman emigrants met their death, either in conflict or subsequently by the axe of the executioner. The whole Aegean fleet of the enemy was annihilated by Lucullus. The war in Bithynia was meanwhile continued by Cotta and by the legates of Lucullus, Voconius, Gaius Valerius Triarius, and Barba, with the land army reinforced by fresh arrivals from Italy, and a squadron collected in Asia. Barba captured in the interior Prusias on Olympus and Nicaea while Triarius along the coast captured Apamea (formerly Myrlea) and Prusias on the sea (formerly Cius). They then united for a joint attack on Mithradates himself in Nicomedia; but the king without even attempting battle escaped to his ships and sailed homeward, and in this he was successful only because the Roman admiral Voconius, who was entrusted with the blockade of the port of Nicomedia, arrived too late. On the voyage the important Heraclea was indeed betrayed to the king and occupied by him; but a storm in these waters sank more than sixty of, his ships and dispersed the rest; the king arrived almost alone at Sinope. The offensive on the part of Mithradates ended in a complete defeat - not at all honourable, least of all for the supreme leader - of the Pontic forces by land and sea.
Invasion of Pontus by Lucullus
Lucullus now in turn proceeded to the aggressive. Triarius received the command of the fleet, with orders first of all to blockade the Hellespont and lie in wait for the Pontic ships returning from Crete and Spain; Cotta was charged with the siege of Heraclea; the difficult task of providing supplies was entrusted to the faithful and active princes of the Galatians and to Ariobarzanes king of Cappadocia; Lucullus himself advanced in the autumn of 681 into the favoured land of Pontus, which had long been untrodden by an enemy. Mithradates, now resolved to maintain the strictest defensive, retired without giving battle from Sinope to Amisus, and from Amisus to Cabira (afterwards Neocaesarea, now Niksar) on the Lycus, a tributary of the Iris; he contented himself with drawing the enemy after him farther and farther into the interior, and obstructing their supplies and communications.
Lucullus rapidly followed; Sinope was passed by; the Halys, the old boundary of the Roman dominion, was crossed and the considerable towns of Amisus, Eupatoria (on the Iris), and Themiscyra (on the Thermodon) were invested, till at length winter put an end to the onward march, though not to the investments of the towns. The soldiers of Lucullus murmured at the constant advance which did not allow them to reap the fruits of their exertions, and at the tedious and - amidst the severity of that season - burdensome blockades. But it was not the habit of Lucullus to listen to such complaints: in the spring of 682 he immediately advanced against Cabira, leaving behind two legions before Amisus under Lucius Murena. The king had made fresh attempts during the winter to induce the great-king of Armenia to take part in the struggle; they remained like the former ones fruitless, or led only to empty promises. Still less did the Parthians show any desire to interfere in the forlorn cause. Nevertheless a considerable army, chiefly raised by enlistments in Scythia, had again assembled under Diophantus and Taxiles at Cabira. The Roman army, which still numbered only three legions and was decidedly inferior to the Pontic in cavalry, found itself compelled to avoid as far as possible the plains, and arrived, not without toil and loss, by difficult bypaths in the vicinity of Cabira, At this town the two armies lay for a considerable period confronting each other.
The chief struggle was for supplies, which were on both sides scarce: for this purpose Mithradates formed the flower of his cavalry and a division of select infantry under Diophantus and Taxiles into a flying corps, which was intended to scour the country between the Lycus and the Halys and to seize the Roman convoys of provisions coming from Cappadocia. But the lieutenant of Lucullus, Marcus Fabius Hadrianus, who escorted such a train, not only completely defeated the band which lay in wait for him in the defile where it expected to surprise him, but after being reinforced from the camp defeated also the army of Diophantus and Taxiles itself, so that it totally broke up. It was an irreparable loss for the king, when his cavalry, on which alone he relied, was thus overthrown.
Victory of Cabira
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 d
elay, 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.
