anon for this-
“Dulce et Decorum Est” is not one I ever heard of, but I don’t know much about poems (most of those I remember are from school assignments, or randomly stumbled across, a la “Mimsy Were The Borogoves” in the sci-fi short by the same name).
I can see that it paints a clear and vivid picture of the misery of a WWI infantryman, and the denouement of the “heroic death” sentiment expressed in the title reminds me of “All Quiet On The Western Front” – when the soldiers tricked into joining the army get to confront their old schoolmaster, “Territorial Kantorek”, about his exhortations to join up.
