Warren Hamilton Lewis was an Irish historian and officer in the British Army, best known as the elder brother of the author and professor C. S. Lewis. Warren Lewis was a supply officer with the Royal Army Service Corps of the British Army during and after the First World War. After retiring in 1932 to live with his brother in Oxford, he was one of the founding members of the "Inklings", an informal Oxford literary society. He wrote on French history, and served as his brother's secretary for the later years of C. S. Lewis's life.
Early life
C. S. Lewis referred to his older brother Warren as “my dearest and closest friend.” The lifelong friendship was formed as the boys played together in their home Little Lea, on the outskirts of Belfast, writing and illustrating stories for their created world called "Boxen". In 1908, their mother died from cancer and as their father mourned her, C. S. and Warren Lewis had only each other for comfort and support. Soon after their mother's death, Jack was sent across the Irish Channel to join Warren at an English boarding school named Wynyard in Watford, Hertfordshire, just northwest of London, where they both endured a harsh headmaster named Robert Capron. Warren had been taken there by his mother Flora on 10 May 1905. In 1909, Warren transferred to Malvern College in Worcestershire and was followed there by his brother a few years later. Warren completed his education at Malvern in 1913.
Military service
He had private studies with William T. Kirkpatrick for four months in preparation for the army entrance exam, beginning on 10 September 1913, and finished 21st among over 201 candidates taking the exam, entitling him to a "prize cadetship", with which he entered the Royal Military College at Sandhurst on 4 February 1914. This gave him a reduction in the fees payable for his attendance. He was commissioned on 29 September as a second lieutenant into the Royal Army Service Corps after only nine months of training. This was due to wartime need; the normal course of study was 18 months to two years. He passed out of the Royal Military College on 1 October, and was sent to France on 4 November 1914 to serve with the 4th Company 7th Divisional Train in the British Expeditionary Force. After World War I, Warren served in such postings as Belgium, Aldershot, Sierra Leone, Colchester, Woolwich, and China. He retired on 21 December 1932 with the rank of Captain, after 18 years of active service. He was granted the temporary rank of Major when recalled to active service on 4 September 1939. After World War II, he took up residence with his brother at a house named The Kilns at Headington, near Oxford, where he lived until the death of C. S. Lewis in 1963. Warren Lewis was buried in the churchyard of Holy Trinity Church, Headington, Oxford, where he is interred in his brother's grave.
Personal life
Warren Lewis renewed his Christian faith beginning in May 1931. He was a frequent participant in weekly meetings of the Inklings and recorded comments about them in many of his diary entries. During the 1930s, the Lewis brothers undertook eight annual walking tours of as many as 50 miles, which Warren years later recalled with fondness, saying, "And jolly good fun they were too." According to C. S. Lewis's letters to Arthur Greeves, Warren Lewis was an alcoholic.
Writings
Soon after his first retirement in 1932, Warren Lewis edited the Lewis family papers. During his final retirement, he began researching a topic of his lifelong interest: the history of 17th-century France. He published seven books on France during the reign of Louis XIV under the name W. H. Lewis, including The Splendid Century: Some Aspects of French Life in the Reign of Louis XIV and Levantine Adventurer: The travels and missions of the Chevalier d'Arvieux, 1653–1697. An excerpt from The Splendid Century appeared first in Essays Presented to Charles Williams, a volume edited by his brother as an informal Festschrift to benefit Williams's widow. After C. S. Lewis died in 1963, Warren edited the first published edition of his brother's letters, adding a memoir of his brother as a preface to the letters. Later editions of these letters were edited by Walter Hooper. Before his death, Warren deposited many of the Lewis family papers in the Marion E. Wade Collection of Wheaton College, including surviving papers of C. S. Lewis and himself. In 1982, selections from Warren Lewis's diary were published under the title Brothers and Friends.
