The 28 rhyming lines of “Dulce et Decorum Est” initially resembles a Shakespearean double-sonnet, with two groups of 14 lines in iambic pentameter and the rhyme scheme ABAB CDCD EFEF GG. It does employ exact end rhyme—such as “boots” (Line 5) and “hoots” (Line 7)—which creates a songlike quality. However, the poem doesn’t follow the sonnet rhyme scheme, using quatrains throughout. Owen also breaks his iambic beat, varying lines from six to 12 beats. This, along with the stanza breaks and the use of dashes, creates a poem that undercuts the rigidity of form. A line like “Gas! GAS! Quick, boys!—An ecstasy of fumbling” (Line 9) also employs all caps and a dash to allude to the sensation of the dire quickness of the events. This suggests a growing fragmentation and destabilization, which adds to the sense that order cannot be adhered to when warfare occurs. The use of six syllables in the final line, shorter by half than the other lines, indicates the finality of what it means to die for one’s country.
