As the gloom of night enveloped the Brazen Fortress, Prince Esfandiyar cast aside his merchant disguise and put on his shining coat of mail. Unlocking the massive chests, the hidden Persian champions emerged like starved lions. Meat and wine were served, and after three deep draughts, Esfandiyar rallied his comrades, urging them to put their faith in the Divine and fight for eternal glory on this perilous night.
He divided his force into three detachments: one to secure the caravanserai, one to block the castle gates, and one to strike down the Turanian commanders who had shared his feast the evening before. Esfandiyar himself, flanked by twenty supreme warriors, charged straight for King Arjasp's inner palace like a thunderbolt. Hearing the clash of steel, his captive sisters, Homa and Beh-Afarid, ran out weeping bloody tears. Recognizing his beloved sisters, Esfandiyar gently bade them flee immediately toward his merchant camp where safety and gold awaited them.
With his Indian blade unsheathed, Esfandiyar cleaved through the guards, turning the grand hall into a sea of blood and fallen bodies. Awakened by the tumult, King Arjasp leaped from his bed in dread, donning his coat of mail and Roman helmet. Esfandiyar confronted the Turanian monarch with a roar: 'Here is the retribution for King Luhrasp, sealed with the reign of Vishtaspa!' A titanic duel erupted as blades rained down upon torso and helm. But Esfandiyar's supernatural might prevailed—he shattered Arjasp's defenses, brought the elephant-like king to his knees, and severed his head with a single swift stroke.
A wail of despair pierced the palace as the tyrant fell. Esfandiyar ordered torches lit, secured the women's quarters without touching a single item of plunder, and sealed the royal treasury. Mounting prime Arabian steeds, Esfandiyar placed his sisters upon horses and entrusted the fortress to the Iranian hero Savah, instructing him to display Arjasp's head upon the parapet when the fleeing Turanian troops returned. With one hundred and sixty chosen horsemen, Esfandiyar swept down to the plain to rejoin his brother Pashotan, whose army marveled in awe at the prince's impossible triumph.
