Then Isfendiyar said, "No man can die before his time is come. It behoveth a man of valour to choose ever the shortest path."
Now the Mubids and the nobles who knew the dangers that were hidden in this path sought to deter him, but Isfendiyar would not listen to their voice. So he set forth with his army, and they marched until they came to the spot where the roads divided. Now it needed seven stages to reach the fortress of Arjasp, and at each stage there lurked a danger, and never yet had any man overcome them or passed beneath its walls. But Isfendiyar would not give ear to fear, and he set forth upon the road, and each day he overcame a danger, and each danger was greater than the last. And on the first day he slew two raging wolves, and on the second he laid low two evil Deevs that were clothed as lions, and on the third he overcame a dragon whose breath was poison.
And on the fourth day Isfendiyar slew a great magician who would have lured him into the paths of evil, and on the fifth he slew a mighty bird whom no man had ever struck down. And weariness was not known of Isfendiyar, neither could he rest from his labours, for there was no camping-place in his road of danger. And on the sixth day he was nigh to have perished with his army in a deep snow that fell upon him through the might of the Deevs. But he prayed unto God in his distress, and by the favour of Heaven the snow vanished from under his feet. Then on the seventh day he came nigh to perish in a flood of waters but Isfendiyar overcame them also, and stood before the castle of Arjasp. Now when he beheld it, his heart failed within him, for he saw that it was compassed by a wall of brass, and the thickness thereof was such that four horsemen could ride thereon abreast. So he sighed and said-"This place cannot be taken, my pains have been in vain."
Yet he pondered in his spirit how it might be done, and he knew that only wile could avail. Wherefore he disguised himself in the garb of a merchant, and chose forth from his army a hundred camels, and he loaded them with brocades of Roum and much treasure. A hundred and sixty stalwart warriors too did he choose forth, and he seated them in chests, and the chests he bound upon the backs of the camels.
And when the caravan was ready he marched at its head unto the doors of the fortress.
Now when he was come thither, he craved permission of Arjasp that he might enter and sell unto them that dwelt therein. And Arjasp granted his request, and gave unto him houseroom, and bade him barter his wares in safety. Then Isfendiyar spread forth his goods and unloaded the treasures of the camels, but the chests wherein were hidden the warriors did he keep from the eyes of men. And after he had sojourned a while in the castle he beheld his sisters, and he saw that they were held as slaves, and his heart went out towards them. So he spake to them tenderly, and they knew his voice, and that help was come out to them, but they held their peace and made no sign. And Isfendiyar, when he saw that he was trusted of Arjasp, came before him and asked of him a boon. And Arjasp said that he would grant it. Then Isfendiyar said-"Suffer that ere I go hence I may feast thee and thy nobles, that I may show my gratitude."
And it was done as Isfendiyar desired, and he made a great feast and troubled the heads of the nobles with wine. And when their heads were heavy and the moon was seated upon her silver throne, Isfendiyar arose and let forth his warriors from the chests. Then he fell upon the nobles and slew them, and they weltered in their blood. And with his own hand Isfendiyar struck down Arjasp, and he hung up his sons upon high gallows. Then he made signals unto his army that they should come forth to aid him, for there were yet many men hidden in the fort, and Isfendiyar had but a handful wherewith to withstand them. And they did as he desired, and there was a great slaughter within the brazen fort, but Isfendiyar bare off the victory. Then he took with him his sisters and much booty, and made haste to return unto Iran, and come into the presence of Gushtasp, his father. And the Shah rejoiced in his sight, and he made a great feast, and gave gifts richly unto all his servants. And the mouths of men overflowed with the doughty deeds done of Isfendiyar, and there was gladness throughout the land.
