"The Show" is a poem depicting a soldier's out of body experience upon dying in a battle in World War I. In this poem, as in other poems, Owen's "increasing disgust at the carnage of battle [is] amply evident" (eNotes) and underscores the dream-like characterization of inhuman struggle, inhuman violence and inhuman suffering in battle.
The fact that soldiers in the poem are described as "thin caterpillars," "abundant spawns" and worms is indicative of the poem's conceit that the method of battle is indeed inhuman.
The poem begins with the narrator poised above the scene "from a vague height with Death" and ends with the narrator returning to his body from which the head has been severed. Starkly violent and negative in its imagery, "The Show" puts forward a gruesome picture of the trench warfare of WWI.
The only line that posits some humanity for the soldiers is suggestive of the tragic irony of war. Soldiers are not born to fight and die in battle, but instead are transported there by circumstance and political need.
All migrants from green fields, intent on mire.
Set down in the battle, as it were, these soldiers seem to be "intent on mire" though their real homes are elsewhere in "green" and more innocent places.
The poem is dark and gloomy in its tone and in its content and also offers a comment on the apparent incomprehensibility of trench warfare.
