The young Reginald Stanley had joined the Cambridgeshire Regiment before the First World War. By the time this territorial unit arrived on the battlefield, he was a sergeant. He went to war with his military equipment but also with a sharp mind, a notebook and most remarkable of all, a camera amongst his kit. Many would record their stories in diaries and letters home but few managed to take photos to add to the written record - because the army forbade them to do so. He fought with distinction and determination in the Ypres salient in 1915 but was invalided out of the Cambridgeshires. Back home he felt out of place and determined to be back with his comrades - not for king and country, but because he felt he must be alongside his fellow man, his friends and colleagues. The diary and pictures tell the story of his time with the Cambridgeshires and then with the Army Ordnance Corps.
