By capturing the horrors of the First World War trenches in brutal yet compelling verse, Siegfried Sassoon told the stories that many at the time were not ready to hear.
But while his words remain as vital as when they were written a century ago, his own story is less well told.
Now the life of the soldier poet is being brought to the big screen in a new biopic, Benediction. Written and directed by Terence Davies – best known for autobiographical film Distant Voices, Still Lives – the movie is out on Friday.
