Dire was the wailing among the army of Iran at their sore defeat, and they turned them back discomfited. And they came before the Shah, their hearts torn with anguish. And their hands were crossed upon their breasts, and they were humble as slaves. And Kai Khosrau was angry when he beheld them, and he remembered Firoud, and he railed against Tus, from whom was sprung this evil. And he said-

"Cursed be he and his elephants and his cymbals." And the Shah withdrew from his courts, and he withheld his countenance from the land. So the nobles went out unto Rustem, and entreated of him that he would intercede for them with the Shah. And Rustem did as they desired, and he pleaded for the army and its leaders, and he spake good even of Tus. And Kai Khosrau inclined his ear unto his Pehliva, and he let the light of his countenance shine again upon his army, and he confided unto Tus once more the standard of Kawah, but he made Gew march beside him and restrain his haste.

So they set forth again unto Turan, and Afrasiyab, when he learned of their approach, made ready his army also. And there were joined unto him the hosts of the Khakan of China, and of the Kamous of Kushan, men mighty in the battlefield. And from Ind and all the highlands of Asia there came forth troops unto the aid of Afrasiyab, King of Turan. And he rejoiced thereat, for he was assured that if Rustem came not forth to aid them, the men of Iran could not stand against his host.

Now when the two armies met, many and fierce were the combats waged between them, and blows were given and received, and swords flashed and showers of arrows descended on all sides. And the blood of brave men was shed like unto the shedding of rain from a black cloud. And day by day were the Iranians weakened, for they were smitten with great slaughter, and the number of their dead was past the counting. But Afrasiyab rejoiced in his victory, and his heart shouted within him when he learned after many days that the Iranians were drawn back into the mountains. But Kai Khosrau, when he learned it, was afflicted, and wept sore. Then he sent greeting unto Rustem, his Pehliva, and he craved of him that he would come forth to aid the army, for in him alone could he put his trust. And Rustem said-

"O Shah, since the day that mine arm could wield a mace, I have ever fought the battles of Iran, and it would seem that rest may never come nigh unto me. Yet since I am thy slave, it behoveth me to obey. I am ready to do thy desires."

So he made ready an host to go unto the succour of Iran. And while he did so the army was defeated yet again, and all heart went from the Iranians, and they would have given them over unto their foes. But while they pondered it, there came tidings unto Gudarz that Rustem was drawing nigh. Yet they feared to give way unto belief. But Piran when he heard it was sore discomfited, for he remembered of old the might of Rustem, and he knew that none could stand before it. But the Khakan and the Kamous scoffed at his fears, and they made loud boastings that Rustem should fall by their hands.

Now when some days had passed in this disquietude, it came about one night that, when the moon showed her face above the mountains, like unto a victorious king seated upon a throne of turquoise, a watchman of Iran set up a great cry. And he said-

"The plain is filled with dust, and the night resoundeth with noise. And I behold a mighty army drawing nigh, and they bear torches, and in their midst rideth Rustem the mighty."

When the men of Iran heard this, they set up a great shout, and their hearts seemed to come back into their bodies, and their courage, that had been as dead, returned. And glad was the greeting that they gave unto Rustem the Pehliva. And Rustem mustered them and put them into battle order, and when the sun had wearied of the black veil, and had torn the night asunder, and reappeared unto the world, the men of Iran called upon the host of Turan to come forth in combat. And they defied them unto battle, and they fought with new valour, and they made great havoc in their ranks. And when the evening was come, the day belonged unto Iran.

Then Piran called before him Human the brave, and said unto him-
"The nobles of Iran have found again their courage, since an army is come to their aid. Yet I would know if Rustem be their leader, for him alone do I fear."

And when he learned it his spirit was troubled. But the Kamous mocked him, and sware a great oath that, ere the sun should be set once more, he would have broken the might of Rustem. For he said-

"There is none, not even a mad elephant, that is mine equal in the fight."

So when the day was come, the Kamous challenged Rustem unto single combat. And Rustem strode forth from the camp, and the Kamous met him upon the plain. Then they struggled sore, and wrestled one with another, but in the end Rustem caught the Kamous in the meshes of his cord. And he showed him unto the army, and he asked of them, saying-

"What death desire ye that the Kamous should die, for his hour is come?"

Then he threw him among the nobles, and they made an end of him with their spears, and they flung his body to the vultures.

Now when the Khakan heard of the death of the Kamous, he sware that he would avenge him, and he sent forth a messenger to defy Rustem. But Rustem said unto the messenger-

"I seek no quarrel with the Khakan, and in all your army I desire only to look upon the face of Piran. And I beg of him that he will come forth to greet me, for my heart burneth towards him, because he was afflicted for the death of Saiawush, my foster-son, and because of the good he did unto Kai Khosrau and unto his mother."

So the messenger bare these words unto Piran. And Piran, when he had taken counsel, listened unto the desires of Rustem, and came into his tents. And he said-

"I am Piran, leader of the hosts of Turan. Speak unto me thy name."

And Rustem said, "I am Rustem of Zaboulistan, and I am armed with a mace and a sword of Cabul."

Then he gave him greeting from Kai Khosrau, and he lauded him for the good deeds that he had done unto Saiawush and to his son, and he entreated him that he would turn away from Afrasiyab, and go with him unto Kai Khosrau. And he said-

"Iran desireth not to destroy the innocent. Therefore deliver over unto me the men upon whose head resteth the blood of Saiawush, and we will withdraw our hosts, and there shall be peace in the land."

Then Piran said, "That which thou askest, verily it can never be, for the slayers of Saiawush are near kinsfolk unto Afrasiyab. And because he hath named me the leader of his hosts, it may not be that I abandon them. But I say unto thee, that it would be sweeter unto me to die than to conduct this warfare, and that my heart is torn because I must lift up the sword of enmity against Kai Khosrau, my son."

And Rustem saw that the words that Piran spake were true, and he sorrowed for him. And when they parted it was in friendship, although they knew that battle must rage between them. Then they drew up their armies, and for forty days there was waged a battle, mighty and terrible. And great ravages were committed, and Rustem did deeds of valour, a............
