The poems gathered here, which trace the course of the First World War, are an extraordinary testimony to the almost unimaginable experiences of a combatant in that bitter conflict. Moving from the patriotic optimism of the first few poems (.fighting for our freedom, we are free) to the anguish and anger of the later work (where hope, with furtive eyes and grappling fists / Flounders in mud.), there comes a point when the reality of trench-warfare and its aftershocks move beyond comprehension: Sassoon knows this, and it becomes a powerful element in his art. As a book, the images have a cumulative relentlessness that make it almost impossible to read more than a few poems in one sitting. Siegfried Loraine Sassoon, CBE, MC 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 mental 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.
