"Insensibility" is a poem written by Wilfred Owen during the First World War which explores the effect of warfare on soldiers, and the long- and short-term psychological effects that it has on them.
 The poem's title refers to the fact that the soldiers have lost the ability to feel due to the horrors which they faced on the Western Front during the First World War.
"Futility" is a poem written by Wilfred Owen, one of the most renowned poets of World War I.
 The poem was written in May 1918 and published as no. 153 in "The Complete Poems and Fragments".
 The poem is well known for its departure from Owen's famous style of including disturbing and graphic images in his work; the poem instead having a more soothing, somewhat light-hearted feel to it in comparison.
 A previous secretary of the Wilfred Owen Association argues that the bitterness in Owen's other poems "gives place to the pity that characterises his finest work".
 Futility details an event where a group of soldiers attempt to revive an unconscious soldier by moving him into the warm sunlight on a snowy meadow.
 However, the "kind old sun" cannot help the soldier - he has died.
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".
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".
