In the mean season Kai Kaous had learned of the death of Saiawush his son, and a mighty wailing went forth throughout the land of Iran, so that even the nightingale in the cypress was silent of her song, and the leaves of the pomegranate tree in the forest were withered for sorrow. And the heroes that stood about the throne of Kai Kaous clad themselves in the garb of woe, and bare dust upon their heads in place of helmets. And Rustem, when he learned of it, was bowed to the earth with agony, and for seven days he stirred not from the ground, neither would he let food or comfort come near him. But on the eighth he roused him from the earth, and caused the trumpets of brass to be sounded into the air. And he assembled his warriors, and marched with them into Iran, and he came before Kai Kaous and demanded audience.
Now when he was come into the presence-chamber he found the Shah seated upon his throne. He was clothed in dust from his head unto his feet, because of his grief. But Rustem regarded it not, and straightway reproached him, and said-"O King of evil nature, behold the harvest that is sprung from the seed that thou didst sow! The love of Sudaveh and her vile intents have torn from off thy head the diadem of kings, and Iran hath suffered cruel loss because of thy folly and thy suspicions. It is better for a king that he be laid within his shroud than that he be given over to the dominion of a woman. Alas for Saiawush! Was ever hero like unto him? And henceforward I will know neither rest nor joy until his cruel death be avenged."
When Kai Kaous had listened to the words of his Pehliva, the colour of shame mounted into his cheek, but he held his peace, for he knew that the words spoken of Rustem were deserved. Then Rustem, when he saw that the King answered him not, strode out from his presence.
And he went into the house of the women, and sought for Sudaveh, who had given over Saiawush unto death. And when he had found her, he tore her from off her throne, and he plunged his dagger into her heart, and he quitted her not until the life was gone from her. And Kai Kaous, when he learned it, trembled and was afraid, for he dared not oppose himself unto Rustem. Then Rustem commanded that the army of vengeance be made ready. And he said-"I will make the earth to tremble before my mace, as it shall tremble on the day of judgment."
And when all was prepared they made them haste to be gone, and the air was full of the gleaming of armour, and the rattling of drums was heard on all sides.
Now when Afrasiyab learned that a great army was come forth from Iran to avenge the death of Saiawush, he bade Sarkha, the best beloved of his sons, lead forth the hosts of Turan against them. But he craved Sarkha have a care that Rustem, the son of Zal, put not his life in danger. And Sarkha set forth, bearing aloft the black banner of Turan, and he went towards the plains where Rustem was encamped. Now when the armies beheld one another, their hearts were inflamed, and the battle raged sore, and many were the brave heads laid low on that day. And Sarkha fell into the hands of Rustem, and he spared him not, because he was the best beloved son of Afrasiyab. So he gave orders that Sarkha be slain, even as Saiawush was slain, that the heart of his enemy might be rent with anguish.
And when Afrasiyab learned it he was beside himself with grief. And when he had torn his hair and wailed in the dust for his son, he arose to go forth unto the army, that he might avenge his death. And he said unto his knights-"Henceforth ye must not think of sleep or hunger, neither must ye breathe aught but vengeance, for I will never stay my hand until this murder be avenged."
Now when the army that was with Afrasiyab came nigh unto Rustem, Pilsam, that was brother to Piran, a warrior valiant and true, challenged Rustem unto single combat. Then Piran sought to stay him because of his youth, but Pilsam listened not unto his counsel. So Rustem came forth against him, and he was armed with a stout lance, and he was wrapped about with his anger. And he fell upon Pilsam with fury, and he lifted him from his saddle, and he took him by the girdle and flung him, as a thing that is vile, into the midst of the camp of the Turanians.
Then he shouted with a voice of thunder-"I counsel you, wrap ye this man in robes of gold, for my mace hath made him blue."
Now when the Turanians beheld that Pilsam was dead, they wept sore, and their courage departed from out of them. And in vain did Afrasiyab pray them to keep their hearts. Yet he said within himself-"The good fortune that watched over me is asleep."
And when they were met in battle yet again, and the army of Rustem had beaten down once more that of Afrasiyab, the King bethought him of flight. And the hosts of Turan vanished like to the wind, but they left behind them much riches and goodly treasure.
Now while they were flying from the face of Rustem, Afrasiyab said unto Piran-"Counsel me how I shall act concerning this child of Saiawush."
And Piran said, "Haste not to put him to death, for he shall in nowise do thee hurt. But if thou wilt listen unto my voice, send him far into Khoten, that he be hidden from sight, and that the men of Iran learn not of his being."
And Afrasiyab did as Piran counselled, and a messenger was sent forth to lead out the young King and his mother unto the land of Cathay.
And Afrasiyab himself fled until that he came within the borders of China, and no man knew where he was hidden. And the land of Turan was given over to plunder, and the Iranians scathed it with fire and sword because of Saiawush, whom Afrasiyab had foully slain. And Rustem seated himself in the seat of Afrasiyab, and for the space of seven years did he rule over the land. But in the eighth messengers came out to him, and said how that Kai Kaous was without a guide in Iran, and how they feared lest folly might result from his deeds. So Rustem went forth to stand beside his Shah.
