Elephants Stand in Pools of Red

From A6.20, Manuchehr Attacks the Army of Tur. It illustrates A6.20.23–29:

A6.20.23
The signal sounded from the bull-elephant’s height;The earth swayed like the Nile beneath their might.
A6.20.24
Before the elephants the drummers cried,While roaring, seething beasts surged at their side.
A6.20.25
From karnay blast and wailing karnay sound,One might have thought a feast had filled the ground.
A6.20.26
They moved like mountains surging through the fray;Both armies roared and thundered on their way.
A6.20.27
The plain became a sea of crimson flow,As tulips bloomed across the earth below.
A6.20.28
The elephants stood fixed in pools of red,Like bijadeh columns where the armies bled.
A6.20.29
The field belonged to Iran’s youthful king,And love for him filled every living thing.
