full_context: Document 1: W. H. Auden: Wystan Hugh Auden ( ; 21 February 1907 – 29 September 1973) was an English-American poet. Auden's poetry was noted for its stylistic and technical achievement, its engagement with politics, morals, love, and religion, and its variety in tone, form and content. He is best known for love poems such as "Funeral Blues", poems on political and social themes such as "September 1, 1939" and "The Shield of Achilles", poems on cultural and psychological themes such as "The Age of Anxiety", and poems on religious themes such as "For the Time Being" and "Horae Canonicae."
Document 2: Wilfred Owen: Wilfred Edward Salter Owen, MC (18 March 1893 – 4 November 1918) was an English poet and soldier, one of the leading poets of the First World War. His war poetry on the horrors of trenches and gas warfare was heavily influenced by his mentor Siegfried Sassoon, and stood in stark contrast both to the public perception of war at the time and to the confidently patriotic verse written by earlier war poets such as Rupert Brooke. Among his best-known works – most of which were published posthumously – are "Dulce et Decorum est", "Insensibility", "Anthem for Doomed Youth", "Futility", "Exposure" and "Strange Meeting".

Document 6: 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.

Document 15: A. E. Housman: Alfred Edward Housman ( ; 26 March 1859 – 30 April 1936), usually known as A. E. Housman, was an English classical scholar and poet, best known to the general public for his cycle of poems "A Shropshire Lad". 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.
