1884–1965
A British Army officer turned author, he is best remembered for a vivid first-hand account of the Gallipoli campaign. His writing brings the strain, confusion, and endurance of wartime service into sharp focus.

by John Graham Gillam
Major John Graham Gillam was a British officer in the Army Service Corps and the author of Gallipoli Diary, first published in 1918. The book grew out of his own experience as a supply officer during the Gallipoli campaign, giving readers a personal view of the daily realities behind one of the First World War’s most difficult operations.
Available records also show that he later wrote The Crucible: The Story of Joseph Priestley, a biography published in 1954. That range—from wartime memoir to historical biography—suggests a writer drawn both to lived experience and to the lives of notable figures from the past.
He is also mentioned in accounts of the wartime Diamond Troupe, the concert party of the 29th Division, where he was described as its first commanding officer and as someone with a talent for producing operatic scenes. Taken together, these glimpses show a man whose life joined military service, writing, and a clear interest in performance and storytelling.
