When Perozes, having invaded the Ephthalite territory, fell in with the army of the enemy, the latter pretended to be seized with a panic, and at once took to flight.  The retreat was directed upon a portion of the mountain region, where a broad and good road led into a spacious plain, surrounded on all sides by wooded hills, steep and in places precipitous.  Here the mass of the Ephthalite troops was cunningly concealed amid the foliage of the woods, while a small number, remaining visible, led the Persians into the cul-de-sac, the whole army unsuspectingly entering, and only learning their danger when they saw the road whereby they had entered blocked up by the troops from the hills.  The officers then apprehended the true state of the case, and perceived that they had been cleverly entrapped; but none of them, it would seem, dared to inform the monarch that he had been deceived by a stratagem.  Application was made to Eusebius, whose ambassadorial character would protect him from an outbreak, and he was requested to let Perozes know how he was situated, and exhort him to endeavor to extricate himself by counsel rather than by a desperate act.  Eusebius upon this employed the Oriental method of apologue, relating to Perozes how a lion in pursuit of a goat got himself into difficulties, from which all his strength could not enable him to make his escape.  Perozes apprehended his meaning, understood the situation, and, desisting from the pursuit, prepared to give battle where he stood.  But the Ephthalite monarch had no wish to push matters to extremities.  Instead of falling on the Persians from every side, he sent an embassy to Perozes and offered to release him from his perilous situation, and allow him to return with all his troops to Persia, if he would swear a perpetual peace with the Ephthalites and do homage to himself as his lord and master, by prostration.  Perozes felt that he had no choice but to accept these terms, hard as he might think them.  Instructed by the Magi, he made the required prostration at the moment of sunrise, with his face turned to the east, and thought thus to escape the humiliation of abasing himself before a mortal by the mental reservation that the intention of his act was to adore the great Persian divinity.  He then swore to the peace, and was allowed to return with his army intact into Persia.

It seems to have been soon after the conclusion of his disgraceful treaty that serious troubles once more broke out in Armenia.  Perozes, following out the policy of his father, Isdigerd, incessantly persecuted the Christians of his northern provinces, especially those of Armenia, Georgia, and Albania.  So severe were his measures that vast numbers of the Armenians quitted their country, and, placing themselves under the protection of the Greek Emperor, became his subjects, and entered into his service.  Armenia was governed by Persian officials, and by apostate natives who treated their Christian fellow-countrymen
