Wilfred Owen, a soldier who was killed in 1918, opens "Spring Offensive" with a rest, not a battle. Men lie in the shade of a hill, fed and drowsy, while others stand staring at "the stark, blank sky beyond the ridge," knowing "their feet had come to the end of the world." From that pause the poem follows them over the ridge and into the charge, then ends on an unsettling question about the survivors. Its central idea is that the earth itself seems to beg these men to stay alive, and that what happens next, and what the survivors cannot say about it, lies beyond any language of glory.
The setting is never named, but the details are physical and sensuous. Summer "oozed into their veins / Like the injected drug for their bones' pains," so beauty works like morphine, soothing and seductive. Buttercups "blessed with gold their slow boots," and brambles "clutched and clung to them like sorrowing hands." Nature behaves like a reluctant parent, unwilling to let go. Yet even here the landscape is double-edged: the "imminent line of grass" hangs sharp on the men's souls, and the sky's "mysterious glass" flashes "fearfully." When the order comes, it is only "the little word," arriving "like a cold gust." There are no bugles, no "high flags," no "clamorous haste." Owen strips the moment of its usual heroic noise. The men's eyes meet the sun "like a friend with whom their love is done," and their smile shines larger than the sun's, as if they are giving up the warmth they have been offered.
Then the pastoral turns. "Soft sudden cups / Opened in thousands for their blood" takes the language of flowers and makes it a language of wounds, with the ground drinking. The "green slopes / Chasmed and steepened sheer to infinite space," so the abyss the men sensed at "the end of the world" becomes literal. The sky that was blank now "burned / With fury against them."
The sound of the poem works in the same unsettling way. The rhymes are irregular and the stanzas uneven. Owen often uses pararhyme, where the consonants match but the vowels shift, as in "world" and "swirled." The rhyme almost lands but does not quite, which suits a poem about a calm that is not safe. Full rhymes such as "veins" and "pains" or "grass" and "glass" sound neat and pretty exactly where the imagery is most deceptive. The rhymes also spill across stanza breaks. "Unstirred," ending the short, held-breath line "They breathe like trees unstirred," is answered by "word" and "begird" in the next stanza, so the order seems to pull the men forward. The line "Knowing their feet had come to the end of the world" runs longer than the pentameter around it, as though the ground has stretched under them.
The last stanza is the strangest. "Some say God caught them even before they fell" is offered as hearsay, a comfort that the poem does not endorse. Instead Owen turns to the few who "rushed in the body to enter hell" and there out-fiended "all its fiends and flames / With superhuman inhumanities." His pairing of "Long-famous glories, immemorial shames" sets honour and disgrace side by side without choosing between them. The poem ends on a question that rhymes "wonder" with "under" and then leaves it unanswered: "Why speak they not of comrades that went under?" The poem does not say why. Judging by the preceding lines, the survivors may be silent because of what they themselves did, or because the experience cannot be put into words.
That refusal to console is what makes the poem matter. Spring, the season of renewal, becomes a trap, and the word "offensive" carries its military meaning along with a sense of outrage. The poem questions both the comfort of religion and the pride of war stories, and it leaves its reader with a silence that the survivors keep.
