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.

Memoirs of an Infantry Officer is a novel by Siegfried Sassoon, first published in 1930.
 It is a fictionalised account of Sassoon's own life during and immediately after World War I.
 Soon after its release, it was heralded as a classic and was even more successful than its predecessor, "Memoirs of a Fox-Hunting Man".
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".
A Theft is a 1989 novel by the American author Saul Bellow.
 Bellow originally wanted to publish the book as a story or serial in a magazine such as "The New Yorker", but his agent had trouble selling it to any magazine.
 Bellow, instead, chose to publish it as a book, and it was his first book to be published in paperback form, which was something highly unusual for a book written by an erudite and respected author.
 Bellow himself said on the television show "Good Morning America" that the book had the quality of a hardcover book, but lacked the requisite number of pages and, hence, was published as a trade paperback.
The Bellarosa Connection is a 1989 novella by the American author Saul Bellow.
 The book takes the form of an ongoing dialogue between the Fonstein family about the impact of the Jewish Holocaust.
 This is an especially significant story as it represents, along with "Mr. Sammler's Planet", Bellow's most significant commentary on the Holocaust.
 In the book, the Bellarosa Connection signifies Billy Rose's Madison Square Garden benefit for the Jews of Europe on the most immediate level, but, more deeply, becomes a point of departure for Bellow to consider the American Jewish response to European Jews' experience during World War II.
 As Bellow's protagonist comes to grips with the past, his experience distances American Jewry's position from that of its European counterparts.
 The book moves then to Israel in order to present the three major homelands of the World's Jewry.
"Memorial Tablet (Great War)" is a poem by Siegfried Sassoon, written in October 1918 and first published in his 1919 collection "Picture-Show".
 The original manuscript is held by Cambridge University Library.
 Sassoon had by this time been invalided out of the army and the war had only a month to run.
Saul Bellow (born Solomon Bellows; 10 June 1915 – 5 April 2005) was a Canadian-American writer.
 For his literary work, Bellow was awarded the Pulitzer Prize, the Nobel Prize for Literature, and the National Medal of Arts.

“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.
