Arrows Rain on Bahram's White Elephant

From E6.25, Soroush Saves Khosrow from Bahram. It illustrates E6.25.25–33:

E6.25.25
Bahram heard Khosrow’s words and knew the snare;Wrath seized his heart; his shame blazed to a flare.
E6.25.26
In fury he would fight without his men,The usurper trusted sword and strength again.
E6.25.27
Upon his elephant he charged the heartOf Khosrow’s center, breaking rank apart.
E6.25.28
The Shah to Andiyan cried, “Lion of might,Make bows a storm and darken all his sight.
E6.25.29
Pour arrows on that elephant like rain;Make springtime clouds of bows across the plain.”
E6.25.30
Iran’s men, blessed by Fortune, strung their bows,And arrow-clouds flew thick against their foes.
E6.25.31
The elephant’s trunk was riddled through and through;Its wounds had turned its hide to indigo-blue.
E6.25.32
Bahram, down from his wounded beast, decreedA helm, and kingly arms, and a fresh steed.
E6.25.33
The arrows showered on his horse like rain;His fury mounted on the battle plain.
