The Burning Engines Rout the Elephants

From D5.15, Iskandar Fights the Army of Foor. It illustrates D5.15.3–7:

D5.15.3
They lit the horses’ naphtha, blazing red;Each Indian in anguish struck his head.
D5.15.4
The black naphtha flared up in sheets of light;The iron army moved into the fight.
D5.15.5
The troops cried out; the elephants were stirredTo rage by blows as battle-shouts were heard.
D5.15.6
Fire caught their trunks; the drivers at the sightStood wondering at that strange and dreadful plight.
D5.15.7
Thus all Foor’s troops and elephants gave way,And fled the burning engines in dismay.
