"The aristocratic general had, by his own account, scored a series of crushing victories, entering the kingdom of Tigranes, defeating the king himself in battle"
entered the kingdom of Tigranes
(king of Pontus, currently at war with Rome) had fled there. Despite the fact that Tigranes and his army had scored many victories in the expansion of his kingdom into an empire, including against the remains of the Seleucid Empire in the east, Lucullus won a crushing victory. The capital city was taken and the king defeated, though Tigranes and Mithridates eluded capture.
