Mustard Gas Asphyxiation

Assembling in trench formations
Firing shells into clouds of smoke
Yellow gas infiltrates your lungs
Blinded by poison and shrapnel

Bleeding internal
Windpipes contract
Asphyxiating
Esophagus turns black

Hopelessly trapped in wire
While you gasp for clean air
Urinating on cloth to weather
Suffocating, I rend my own hair

Bleeding internal
Windpipes contract
Asphyxiating
Esophagus turns black

Coughing blood
From mustard gas
Asphyxiating
Lungs turn black

[Solo: Vomit-inducing trench foot]
