Undertones or War is a 1928 memoir of the First World War, written by English poet Edmund Blunden.
 As with two other famous war memoirs-—Siegfried Sassoon's "Sherston trilogy", and Robert Graves' "Good-Bye to All That"--"Undertones" represents Blunden's first prose publication, and was one of the earliest contributors to the flurry of Great War books to come out of England in the late 1920s and early 1930s.
Edmund Charles Blunden, CBE, MC (1 November 1896 – 20 January 1974) was an English poet, author and critic.
 Like his friend Siegfried Sassoon, he wrote of his experiences in World War I in both verse and prose.
 For most of his career, Blunden was also a reviewer for English publications and an academic in Tokyo and later Hong Kong.
 He ended his career as Professor of Poetry at the University of Oxford.
 He was nominated for the Nobel Prize in Literature six times.
Jessie Pope (18 March 1868 – 14 December 1941) was an English poet, writer and journalist, who remains best known for her patriotic motivational poems published during World War I.
 Wilfred Owen dedicated his 1917 poem "Dulce et Decorum Est" to Pope, whose literary reputation has faded into relative obscurity as those of war poets such as Owen and Siegfried Sassoon have grown.
Siegfried Loraine Sassoon, {'1': ", '2': ", '3': 'CBE, MC', '4': "} (8 September 1886 – 1 September 1967) was an English poet, writer, and soldier.
 Decorated for bravery on the Western Front, he became one of the leading poets of the First World War.
 His poetry both described the horrors of the trenches, and satirised the patriotic pretensions of those who, in Sassoon's view, were responsible for a jingoism-fuelled war.
 Sassoon became a focal point for dissent within the armed forces when he made a lone protest against the continuation of the war in his "Soldier's Declaration" of 1917, culminating in his admission to a military psychiatric hospital; this resulted in his forming a friendship with Wilfred Owen, who was greatly influenced by him.
 Sassoon later won acclaim for his prose work, notably his three-volume fictionalised autobiography, collectively known as the "Sherston trilogy".
Base Details is a war poem by the English war poet Siegfried Sassoon.
 In the poem Sassoon condemns what he saw as the incompetence and callous indifference to the soldiers at the front displayed by the staff officers, or "scarlet majors" of the British Army, who stayed at the Base "Guzzling and gulping in the best hotel" and sending "glum heroes up the line to death".
 Like so many of Sassoon's poems "Base Details" is bitterly sarcastic and utterly derisive of the comfortable establishment that supported the continuation of the war while showing little concern for the people who suffered its consequences.
 It took place during World War I in France around 1914-1918.
Sherston's Progress is the final book of Siegfried Sassoon's semi-autobiographical trilogy.
 It is preceded by "Memoirs of a Fox-Hunting Man" and "Memoirs of an Infantry Officer".
“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.
The Lark Ascending is a poem of 122 lines by the English poet George Meredith about the song of the skylark.
 Siegfried Sassoon called it matchless of its kind, "a sustained lyric which never for a moment falls short of the effect aimed at, soars up and up with the song it imitates, and unites inspired spontaneity with a demonstration of effortless technical ingenuity... one has only to read the poem a few times to become aware of its perfection".
The Sherston trilogy is a series of books by the English poet and novelist, Siegfried Sassoon, consisting of "Memoirs of a Fox-Hunting Man", "Memoirs of an Infantry Officer", and "Sherston's Progress".
 They are named after the protagonist, George Sherston; a young Englishman of the upper middle-class, living immediately before and during the First World War.
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".
