d into Pontus with 4000 Armenian horsemen and 4000 of his own,
and as liberator and avenger summoned the nation to rise against
the common foe. All joined him; the scattered Roman soldiers
were everywhere seized and put to death: when Hadrianus, the Roman
commandant in Pontus,(19) led his troops against him, the former
mercenaries of the king and the numerous natives of Pontus
following the army as slaves made common cause with the enemy.
For two successive days the unequal conflict lasted; it was only
the circumstance that the king after receiving two wounds had
to be carried off from the field of battle, which gave the Roman
commander the opportunity of breaking off the virtually lost
battle, and throwing himself with the small remnant of his troops
into Cabira. Another of Lucullus' lieutenants who accidentally
came into this region, the resolute Triarius, again gathered round
him a body of troops and fought a successful engagement
with the king; but he was much too weak to expel him afresh
from Pontic soil, and had to acquiesce while the king took up
winter-quarters in Comana.
Farther Retreat to Pontus
So the spring of 687 came on. The reunion of the army in Nisibis,
the idleness of winter-quarters, the frequent absence of the general,
had meanwhile increased the insubordination of the troops;
not only did they vehemently demand to be led back, but it was already
tolerably evident that, if the general refused to lead them home,
they would break up of themselves. The supplies were scanty;
Fannius and Triarius, in their distress, sent the most urgent
entreaties to the general to furnish aid. With a heavy heart
Lucullus resolved to yield to necessity, to give up Nisibis
and Tigranocerta, and, renouncing all the brilliant hopes of his
Armenian expedition, to return to the right bank of the Euphrates.
Fannius was relieved; but in Pontus the help was too late.
Triarius, not strong enough to fight with Mithradates, had taken
up a strong position at Gaziura (Turksal on the Iris, to the west
of Tokat), while the baggage was left behind at Dadasa.
But when Mithradates laid siege to the latter place, the Roman soldiers,
apprehensive for their property, compelled their leader to leave
his secure position, and to give battle to the king between Gaziura
and Ziela (Zilleh) on the Scotian heights.
Defeat of the Romans in Pontus at Ziela
What Triarius had foreseen, occurred. In spite of the stoutest
resistance the wi
