Upon the command of Rashnawad, the host of Iran marched past the boundaries and advanced toward the domains of Rome. Rashnawad bestowed the vanguard of the army upon the young and valiant Darab, whose warrior spears were dipped in venom. At once, the Roman advance guard approached from the west, and the two colossal hosts collided with thunderous impact. A dense cloud of war-dust ascended to the heavens, and blood flowed across the plain like a rushing river.
When Darab beheld the fury of the engagement, he charged forward like a enraged lion. His blade wreaked such havoc among the enemy ranks that it seemed as though Destiny itself held a sword in its iron fist. Like a leviathan parting the sea or a dragon devouring its prey, he clove through the Roman ranks until he breached their very encampment. The earth turned into a crimson ocean beneath his horse's hooves. Returning victorious to the high commander Rashnawad, Darab was met with boundless praise. Rashnawad declared: 'May the King's host never be deprived of thy matchless strength! When we return triumphant, the sovereign shall bestow upon thee crowns, steeds, royal seals, and endless treasures.'
When the sun lifted its head above the dark ridges and illuminated the world like a lamp, the battle resumed. Darab gave his swift charger the reins and breached the heart of the Roman battle line like a ravenous wolf. Neither spear-men nor seasoned swordsmen could withstand his fury. He shattered their right wing, plundered their baggage, slew forty Roman catholicoi, and seized their cross in his fist. Seeing these wondrous deeds, Rashnawad's heart swelled with joy, and he showered the youth with even greater affection and honor.
As night descended and wrapped the plain in pitch, Rashnawad rested within the captured Roman camp and loosened his armor. He distributed vast spoils to his army and sent a messenger to Darab, saying: 'O lion-hearted savior, survey these riches and claim whatever pleases thy heart; give away the rest as thou see fit, for thy name today shines brighter than that of the lord of Rakhsh!' But Darab, possessing a sublime spirit, took only a single spear for the sake of honor and returned all the treasure to the general.
With the coming of dawn, the Iranian heroes pursued the fleeing Romans, putting their strongholds to the sword and fire. A mournful lamentation echoed across Rome as the land was ruined. The world grew narrow for the Roman Caesar, whose champions had lost heart and whose fortune had fallen into shadow. Suing for mercy, Caesar dispatched an envoy to Rashnawad, promising full obedience and annual tribute. He sent vast bags of gold, pristine jewels, and numerous captives. Rashnawad accepted the tribute and forged a solemn covenant of peace, bringing the campaign to a glorious conclusion for Iran.
