The Persians were victorious; Vartan, and his brother, Hemaiiag, were among the slain; and the patriotic party found that no further resistance was possible.

The patriarch, Joseph, and the other bishops, were seized, carried off to Persia, and martyred.

Zoroastrianism was enforced upon the Armenian nation.

All accepted it, except a few, who either took refuge in the dominions of Rome, or fled to the mountain fastnesses of Kurdistan.
The resistance of Armenia was scarcely overborne, when war once more broke out in the East, and Isdigerd was forced to turn his attention to the defence of his frontier against the aggressive Ephthalites, who, after remaining quiet for three or four years, had again flown to arms, had crossed the Oxus, and invaded Khorassan in force.

On his first advance the Persian monarch was so far successful that the invading hordes seems to have retired, and left Persia to itself; but when Isdigerd, having resolved to retaliate, led his own forces into the Ephthalite country, they took heart, resisted him, and, having tempted him into an ambuscade, succeeded in inflicting upon him a severe defeat.
Isdigerd was forced to retire hastily within his own borders, and to leave the honors of victory to his assailants, whose triumph must have encouraged them to continue year after year their destructive inroads into the north-eastern provinces of the empire.
It was not long after the defeat which he suffered in this quarter that Isdigerd's reign came to an end.
