Thirst on the Field of Kadisiya

From E10.4, Rostam Battles Sa’ad and Is Slain. It illustrates E10.4.6–13:

E10.4.6
The armies met, feet planted in the ground;Each held its place amid the battle’s sound.
E10.4.7
Bright spearheads flashed through dust that veiled their sight,Like fiery stars that burn across the night.
E10.4.8
The spears struck helms and failed beneath the strain;Three days the armies battled on the plain.
E10.4.9
Then water grew scarce in the long-drawn fray;Their heavy armor on the warriors lay.
E10.4.10
With burdened souls, the fighters lost their might;Thirst stopped both men and horses in the fight.
E10.4.11
Rostam’s lips dried like dust upon the plain,His tongue was split with thirst and bitter pain.
E10.4.12
Both men and horses fed on moistened clay,So hard the battle pressed them on that day.
E10.4.13
Then Rostam looked across the field ahead,And saw the leaders of his army dead.
