If in some smothering dreams you too could pace Behind the wagon that we flung him in, And watch the white eyes writhing in his face, His hanging face, like a devil's sick of sin; If you could hear, at every jolt, the blood Come gargling from the froth-corrupted lungs, Obscene as cancer, bitter as the cud Of vile, incurable sores on innocent tongues,-- My friend, you would not tell with such high zest To children ardent for some desperate glory, The old Lie: Dulce et decorum est pro patria mori.
"Dulce et Decorum Est" l. 21 (written 1918) See Horace 20
