Document A. Trench Warfare, World War I Document B. Dulce et decorum est* (Excerpt) , Wilfred Owen (1918)
Bent double, like old beggars under sacks,
Knock-kneed, coughing like hags, we cursed through sludge,
Till on the haunting flares we turned our backs
And towards our distant rest began to trudge.
Men marched asleep. Many had lost their boots
But limped on, blood-shod. All went lame; all blind;
Drunk with fatigue; deaf even to the hoots
Of gas-shells dropping softly behind.
*translation: From the Latin phrase "Dulce et decorum est, pro patria mori"
"It is sweet and fitting to die for one's country."
