They spurred their horses, galloping in flight,And fled from Dara’s camp with all their might.

When Dara looked, no crowned head was in sight;The guest had vanished in the dark of night.

At once he sent a watchman out to spyUpon the suspect’s tent that stood nearby.

Iskandar fled before the scout drew near;His fortune had not slept, nor failed him here.
D4.3.67
Dara dispatched a thousand horsemen, bentTo seize Iskandar as he homeward went.

They raced like wind; the night was dark and black,And none could recognize the proper track.
