In the excerpts from "Suicide in the Trenches" by Siegfried Sassoon and "Dulce Et Decorum Est" by Wilfred Owen there are a few lines that show how painful and filty the conditions faced by the soliders in World War I really were.
<em>"Suicide in the Trenches" by Siegfried Sassoon</em>
<em />
"In winter trenches, cowed and glum,
With crumps and lice and lack of rum,"
These lines show that the soldiers were sad and would submit to what others said through intimidation. They were surrounded by loud thudding noises, had lice, and didn't have any rum. The soldiers were being tested physically, mentally, and emotionally with all of this.
<em>"Dulce Et Decorum Est" by Wilfred Owen</em>
"Obscene as cancer, bitter as the cud
Of vile, incurable sores on innocent
tongues,"
These lines show how strange and alien the trenches felt. Many of the soldiers were physically and mentally damaged in a way that could never be repaired.
