When tidings reached King Afrasiab that young Sohrab had readied a fleet and assembled a mighty host, the monarch of Touran rejoiced. Though the fragrance of milk still lingered upon the youth's lips, his mind craved only the clash of steel, the flight of arrows, and a duel against King Kavus. Desiring to exploit this fierce newcomer, Afrasiab selected twelve thousand chosen war-veterans who wielded heavy maces, placing them under the command of his two premier generals, Houman and Barman.
In secrecy, the Touranian king instructed his captains that the supreme secret must be guarded at all costs: under no circumstances should Sohrab be allowed to recognize Rostam as his father. For if the son learned of his parentage, natural affection would stay his hand. Afrasiab nursed the dark hope that the veteran champion Rostam might fall by the hand of this lion-hearted boy, after which Sohrab himself could easily be disposed of, leaving Iran defenseless. Houman and Barman set forth bearing lavish royal tribute—ten saddled horses, ten laden mules, a turquoise throne, a ruby crown—and a cunning letter from Afrasiab offering military alliance and encouraging Sohrab to seize the Iranian throne.
Upon learning of the arriving host, Sohrab rode out to welcome Houman and Barman. Astonished by the boy's titan-like physique, Houman presented the King's missive and treasures. Enthralled, Sohrab immediately mobilized his armies and marched toward the Iranian frontier, sweeping aside all resistance. He soon reached the White Fortress (Dezh-e Sepid), a vital border bastion defended by the battle-tested warrior Hajir.
Spotting the oncoming vanguard, Hajir mounted his swift charger and galloped into the plain to confront the invaders. Sohrab drew his sword and rode out to meet him. Hajir haughtily demanded the youth's name and lineage, threatening to send his severed head to King Kavus. Sohrab merely laughed at his bravado and charged. The two warriors clashed violently with lances until Sohrab struck Hajir with the butt of his spear, hoisting him bodily out of the saddle like a gust of wind and slamming him to the earth. Sohrab dismounted, pinned Hajir down, and drew his blade to slay him. Desperate, Hajir begged for his life. Sohrab granted him mercy, bound his hands, and sent him captive to Houman's tent, leaving the defenders of the White Fortress weeping in terror.
