The images are published in a new book called The Somme: A Visual History, by Anthony Richards who is head of Documents and Sound at the Imperial War Museums.

As the book’s publisher, the Imperial War Museums said: ‘Rarely seen photographs captured by the official war photographers at the front, vivid wartime posters and artworks showing the horrors and sheer scale of the battle are woven throughout the narrative of the book, illustrating it with the faces and images of the time.’

The book also relays the first-hand experiences of those who took part in the battle, plucked from private diaries, personal letters and interviews.

Taylor Downing, a historian, said: ‘This is a unique account of Britain’s most famous battle. The book is full of the most brilliant images, including many little known photos but also much artwork, engravings and posters of the time.’
