Night Falls and Dara's Line Breaks

From D4.6, Iskandar Fights Dara and Dara Flees. It illustrates D4.6.6–11:

D4.6.6
The monarchs drew their armies forth to stand,With spear and gorz and khanjar held in hand.
D4.6.7
The armies’ clamor thundered to the sphere,And tore, it seemed, the turning heaven’s ear.
D4.6.8
The earth became a sea of streaming red,And headless trunks lay mingled with the dead.
D4.6.9
No father could attend his son that day,As faithless fortune turned from men away.
D4.6.10
Night fell, and Dara broke beneath attack;Iskandar girded, set to drive him back.
D4.6.11
The Shah withdrew to Kerman in defeat,To save his life and lead his troops’ retreat.
