Stifling Excruciation

Roaming desolate fields
Companionship abandoned
They have me in their sights
The hardest part is the wait

Hope is lost, survival gone
A stifled virulent agony takes its place

Artillery strikes, sarin is near
I savor all remaining oxygen
Holding onto memories past
I yearn for those painless days

Gaseous mass slithers closer
Penetrating the skin like daggers
Tormented, I writhe in suffocation
As the sarin strangles my innards
