This allows Barker to write about the Great War from an unusual viewpoint, as no real 'battles' take place in Regeneration, at least not in a literal sense. Conventionally, in the canon of literature produced during or in reaction to WW1, combat on the Western Front is a central point of focus, as this is where the war most obviously took place. However, writing from the perspective of psychiatrist William Rivers, Barker is able to explore one of the most startling and dehumanising effects of the war and the battles that took place in the men's minds on their path to recovery.
