In a little time, however, he found that he had been tricked: Perozes had not sent him his daughter, but one of his female slaves; and the royal race of the Ephthalite kings had been disgraced by a matrimonial union with a person of servile condition.

Khush-newaz was justly indignant; but dissembled his feelings, and resolved to repay guile with guile.

He wrote to Perozes that it was his intention to make war upon a neighboring tribe, and that he wanted officers of experience to conduct the military operations.

The Persian monarch, suspecting nothing, complied with the request, and sent three hundred of his chief officers to Khush-newaz, who immediately seized them, put some to death, and, mutilating the remainder, commanded them to return to their sovereign, and inform him that the king of the Ephthalites now felt that he had sufficiently avenged the trick of which he had been the victim.

On receiving this message Perozes renewed the war, advanced towards the Ephthalite country, and fixed his head-quarters in Hyrcania, at the city of Gurgan, He was accompanied by a Greek of the name of Eusebius, an ambassador from the Emperor Zeno, who took back to Constantinople the following account of the campaign.
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.
