Which British Army regiment did C.S. Lewis serve with in World War I?

C.S. Lewis served with the Somerset Light Infantry during World War I. He was commissioned in the regiment and sent to France in 1917.

Lewis fought on the Western Front and was wounded at the Battle of Arras in April 1918. The experience affected his life and later writing, although his books are not simple military memoirs. His close friend Paddy Moore was killed during the war.

After recovering from his wound, Lewis returned to England and was discharged from the army in December 1918. He then resumed his education at Oxford, where his academic career eventually took shape.

The regiment’s name is sometimes shortened incorrectly in casual references. The historically precise answer is the Somerset Light Infantry, a British infantry regiment that later became part of the Somerset and Cornwall Light Infantry through army reorganizations.
