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
