Document 8: Suicide in the Trenches: “Suicide in the Trenches,” by the English poet Siegfried Sassoon (1886-1967), is one of the many poems Sassoon composed in response to World War I. It reflects his own notable service in that especially bloody conflict. Sassoon was a brave and gallant upper-class officer who eventually opposed the war, but he never lost his admiration for the common soldiers who had to fight it. Sassoon felt contempt for the political leaders and civilian war hawks who, safe in their power and comfort, sent young men off to die in huge battles that seemed futile and pointless. It was first published February 23, 1918 in "Cambridge Magazine", then in Sassoon's collection: "Counter-Attack and Other Poems". The poem is written in iambic tetrameter and consists of twelve lines in three stanzas.

Lyrical and almost epigrammatic in form, the poems wistfully evoke the dooms and disappointments of youth in the English countryside. Their beauty, simplicity and distinctive imagery appealed strongly to late Victorian and Edwardian taste, and to many early 20th-century English composers both before and after the First World War. Through their song-settings, the poems became closely associated with that era, and with Shropshire itself.
