The Army Buried in Snow

From B12.15, The Snowstorm Campaign. It illustrates B12.15.7–13:

B12.15.7
Upon the Iranian side a tempest rose,And none gave thought to battle with their foes.
B12.15.8
A dense cloud came like dust across the sky,The cold froze lips to teeth as it swept by.
B12.15.9
The tents and pavilions froze in white;Snow drew a thread across each mountain height.
B12.15.10
For seven days the earth was lost to sight,And vanished underneath the storm’s white might.
B12.15.11
They found scant food, scant rest, and little sleep;And stone-like earth lay frozen hard and deep.
B12.15.12
They slew and ate their horses in despair;And many men and beasts died everywhere.
B12.15.13
At last no hand or arm had strength to rise;The troops lay broken under frozen skies.
