When we think of Siegfried Sassoon, we think of World War One – his brutally realistic poems about the trenches, his anger, how he narrowly escaped death so many times. The war was the defining of Sassoon’s life and his career as a writer… But it lasted only four years and was over when he was only thirty-two. In this 639-page biography, the war ends around the 200th page. Then what? This was a question that plagued Sassoon all his life – and one his biographer, Max Egremont, struggles with as well. What happens after the worst has passed? How do you move on? What is left?
