Saying this, he dismounted from his famous black horse, called Behzád, the gift of Kai-khosráu, and presented it to Isfendiyár. The greatest clamor and lamentation had arisen among the Persian army, for they thought that Bai-derafsh had committed such dreadful slaughter, the moment of utter defeat was at hand, when Isfendiyár galloped forward, mounted on Behzád, and turned the fortunes of the day. He saw the demon with the mail of Zarír on his breast, foaming at the mouth with rage, and called aloud to him, "Stand, thou murderer!" The stern voice, the valor, and majesty of Isfendiyár, made the demon tremble, but he immediately discharged a blow with his dagger at his new opponent, who however seized the weapon with his left hand, and with his right plunged a spear into the monster's breast, and drove it through his body. Isfendiyár then cut off his head, remounted his horse, and that instant was by the side of Bishú, the son of the vizir, into whose charge he gave the severed head of Bai-derafsh, and the armor of Zarír. Bishú now attired himself in his father's mail, and fastening the head on his horse, declared that he would take his post close by Isfendiyár, whatever might betide. Firshaid, another Iránian warrior, came to the spot at the same moment, and expressed the same resolution, so that all three, thus accidentally met, determined to encounter Arjásp and capture him. Isfendiyár led the way, and the other two followed. Arjásp, seeing that he was singled out by three warriors, and that the enemy's force was also advancing to the attack in great numbers, gave up the struggle, and was the first to retreat. His troops soon threw away their arms and begged for quarter, and many of them were taken prisoners by the Iránians. Gushtásp now approached the dead body of Zarír, and lamenting deeply over his unhappy fate, placed him in a coffin, and built over him a lofty monument, around which lights were ever afterwards kept burning, night and day; and he also taught the people the worship of fire, and was anxious to establish everywhere the religion of Zerdusht. Jamásp appointed officers to ascertain the number of killed in the battle. Of Iránians there were thirty thousand, among whom were eight hundred chiefs; and the enemy's loss amounted to nine hundred thousand, and also eleven hundred and sixty-three chiefs. Gushtásp rejoiced at the glorious result, and ordered the drums to be sounded to celebrate the victory, and he increased his favor upon Zerdusht, who originated the war, and told him to call his triumphant son, Isfendiyár, near him. The gallant youth the summons hears, And midst the royal court appears, Close by his father's side, The mace, cow-headed, in his hand; His air and glance express command, And military pride.
