Once King Bahram Gur and his victorious host rested in Merv and cast off the weariness of hard battle, the sovereign turned his eyes toward Bukhara. Orders were given to saddle the warhorses, and the Iranian army swept toward the crossing of Amuy. Enjoying falconry and the chase along the journey, Bahram reached the waters of Amuy in the dead of night, treading the heavy sands of Farab. As dawn turned the sky golden and cast away the azure mantle of night, the billowing dust of the marching hosts rose like the feathers of a falcon, casting its shadow across the lands of May and Morgh.
Panic seized the realm of Turan at the approach of the Iranian host. The Turkish army shattered in terror, setting fire to their own fields and encampments out of sheer dread. Elder lords and young warriors alike hastened before Bahram Gur—barefoot, humbled, covered in dust, their hearts bleeding with anguish. Casting themselves down, they pleaded: 'O King of sublime destiny! If the Khaqan sinned and severed his holy oath, he has already fallen into your net of justice. Do not shed the blood of the innocent, for waging war against the helpless brings no honor to great names. If it is tribute you seek, we are your humble servants and yield to your command.'
At their desperate pleas, wisdom stayed the hand of Bahram’s wrath, and compassion filled his royal heart. The God-fearing King commanded his warriors to sheath their blades. Reassured by the monarch's mercy, the chief of the Turkish elders swore solemn allegiance, agreeing to send a heavy annual tribute to the throne of Iran. His heart satisfied, Bahram returned triumphant to Farab, where he rested his forces for a week. There, he summoned the noble elders of Chin and commanded that a monumental pillar of stone and mortar be erected on the banks of the Oxus (Jayhun), declaring that no Turk or Khalaj warrior might cross into Iranian territory without royal permission, establishing the river as the eternal arbiter of the realm.
To ensure lasting peace, Bahram selected from his army a wise, noble-born chieftain named Shamr, renowned for his sound judgment and stature. Bahram crowned Shamr with a golden moon-crested diadem, investing him as King over the realm of Turan, bringing newfound joy and justice across the lands beyond the river.
