The darkness crumbles away  
It is the same old druid Time as ever,  
Only a live thing leaps my hand,  
A queer sardonic rat,  
As I pull the parapet's poppy 
To stick behind my ear.  
Droll rat, they would shoot you if they knew  
Your cosmopolitan sympathies,  
Now you have touched this English hand  
You will do the same to a German 
Soon, no doubt, if it be your pleasure  
To cross the sleeping green between.  
It seems you inwardly grin as you pass  
Strong eyes, fine limbs, haughty athletes,  
Less chanced than you for life, 
Bonds to the whims of murder,  
Sprawled in the bowels of the earth,  
The torn fields of France.  
What do you see in our eyes  
At the shrieking iron and flame 
Hurled through still heavens?  
What quaver -what heart aghast?  
Poppies whose roots are in men's veins  
Drop, and are ever dropping;  
But mine in my ear is safe, 
Just a little white with the dust.
Isaac Rosenberg
