War is Kind, was unconventional for the time in that it was written in free verse without rhyme, meter, or even titles for individual works. They are typically short in length and although several poems, such as 'Do not weep, maiden, for war is kind', use stanzas and refrains, most do not. Crane also differed from his peers and poets of later generations in that his work contains allegory, dialectic and narrative situations. (source: Wikipedia)
