When the news of Pírán's death reached Kai-khosráu, he rapidly marched forward, crossed the Jihún without delay, and passed through Samerkánd and Bokhára, to encounter the Túránians. Afrásiyáb, in the meantime, had not been neglectful. He had all his hidden treasure dug up, with which he assembled a prodigious army, and appointed his son Shydah-Poshang to the command of a hundred thousand horsemen. To oppose this force, Khosráu appointed his young relative, Lohurásp, with eight thousand horsemen, and passing through Sístán, desired Rustem, on account of Lohurásp's tender age and inexperience, to afford him such good counsel as he required. When Afrásiyáb heard this, he added to the force of Shydah another hundred thousand men, but first sent his son to Kai-khosráu in the character of an ambassador to offer terms of peace. "Tell him," said he, "that to secure this object, I will deliver to him one of my sons as a hostage, and a number of troops for his service, with the sacred promise never to depart from my engagements again.--But, a word in thy ear, Shydah; if Khosráu is not disposed to accept these terms, say, to prevent unnecessary bloodshed, he and I must personally decide the day by single combat. If he refuses to fight with me, say that thou wilt meet him; and shouldst thou be slain in the strife, I will surrender to him the kingdom of Túrán, and retire myself from the world." He further commanded him to propound these terms with a gallant and fearless bearing, and not to betray the least apprehension. Shydah entered fully into the spirit of his father's instructions, and declared that he would devote his life to the cause, that he would boldly before the whole assembly dare Kai-khosráu to battle; so that Afrásiyáb was delighted with the valorous disposition he displayed.
