The Iberian archers however withstood not for a moment the onset of the Roman legions, and, when Artoces saw the Pelorus also crossed by the Romans, he submitted at length to the conditions which the victor proposed, and sent his children as hostages.
Pompeius Proceeds to Colchis Pompeius now, agreeably to the plan which he had formerly projected, marched through the Sarapana pass from the region of the Kur to that of the Phasis and thence down that river to the Black Sea, where on the Colchian coast the fleet under Servilius already awaited him.

But it was for an uncertain idea, and an aim almost unsubstantial, that the army and fleet were thus brought to the richly fabled shores of Colchis.

The laborious march just completed through unknown and mostly hostile nations was nothing when compared with what still awaited them, and if they should really succeed in conducting the force from the mouth of the Phasis to the Crimea, through warlike and poor barbarian tribes, on inhospitable and unknown waters, along a coast where at certain places the mountains sink perpendicularly into the sea and it would have been absolutely necessary to embark in the ships-- if such a march should be successfully accomplished, which was perhaps more difficult than the campaigns of Alexander and Hannibal-- what was gained by it even at the best, corresponding at all to its toils and dangers?
The war doubtless was not ended, so long as the old king was still among the living; but who could guarantee that they would really succeed in catching the royal game for the sake of which this unparalleled chase was to be instituted?
Was it not better even at the risk of Mithradates once more throwing the torch of war into Asia Minor, to desist from a pursuit which promised so little gain and so many dangers?
Doubtless numerous voices in the army, and still more numerous voices in the capital, urged the general to continue the pursuit incessantly and at any price; but they were the voices partly of foolhardy Hotspurs, partly of those perfidious friends, who would gladly at any price have kept the too-powerful Imperator aloof from the capital and entangled him amidst interminable undertakings in the east.
Pompeius was too experienced and too discreet an officer to stake his fame and his army in obstinate adherence to so injudicious an expedition; an insurrection of the Albanians in rear of the army furnished the pretext for abandoning the further pursuit of the king and arranging its return.

The fleet received instructions to cruise in the Black Sea, to protect the northern coast of Asia Minor against any hostile invasion, and strictly to blockade the Cimmerian Bosporus under the threat of death to any trader who should break the blockade.

Pompeius conducted the land troops not without great hardships through the Colchian and Armenian territory to the lower course of the Kur and onward, crossing the stream, into the Albanian plain.
Fresh Conflicts with the Albanians For several days the Roman army had to march in the glowing heat through this almost waterless flat country, without encountering the enemy; it was only on the left bank of the Abas (probably the river elsewhere named Alazonius, now Alasan) that the force of the Albanians under the leadership of Coses, brother of the king Oroizes, was drawn up against the Romans; they are said to have amounted, including the contingent which had arrived from the inhabitants of the Transcaucasian steppes, to 60,000 infantry and 12,000 cavalry.
