Barnwood House Hospital (1860–1968) was a private mental hospital in Barnwood, Gloucester, England.
 It was founded by the Gloucester Asylum Trust in 1860 as Barnwood House Institution and later became known as Barnwood House Hospital.
 The hospital catered for well-to-do patients, with reduced terms for those in financial difficulties.
 It was popular with the military and clergy, and once counted an Archbishop amongst its patients.
 During the late nineteenth century Barnwood House flourished under superintendent Frederick Needham, making a healthy profit and receiving praise from the Commissioners in Lunacy.
 Even the sewerage system was held up as a model of good asylum practice.

A stretcher, litter, or pram is an apparatus used for moving patients who require medical care.
 A basic type (cot or litter) must be carried by two or more people.
 A wheeled stretcher (known as a gurney, trolley, bed or cart) is often equipped with variable height frames, wheels, tracks, or skids.
 In American English, a wheeled stretcher is referred to as a gurney.
 The name comes from a horse-drawn cab patented in the USA by J. Theodore Gurney in 1883 which bore a similarity to early wheeled stretchers.
Joseph Campbell (July 15, 1879 – June 1944) was an Irish poet and lyricist.

 He is now remembered best for words he supplied to traditional airs, such as "My Lagan Love" and "Gartan Mother's Lullaby"; his verse was also set to music by Arnold Bax and Ivor Gurney.
Literature in World War I is generally thought to include poems, novels and drama; diaries, letters, and memoirs are often included in this category as well.

 Many of the works during and about the war were written by men, because of the war's intense demand on the young men of that generation; however, a number of women (especially in the British tradition) created literature about the war, often observing the effects of the war on soldiers, domestic spaces, and the homefront more generally.
