What was J.R.R. Tolkien’s wartime army regiment during World War I?

J.R.R. Tolkien served in the Lancashire Fusiliers during World War I.

Tolkien was commissioned as a second lieutenant in the Lancashire Fusiliers in 1915 after graduating from Oxford. He served on the Western Front and took part in the Battle of the Somme in 1916. He later became ill with trench fever and was sent back to England for treatment.

Most of the officers in Tolkien’s battalion were killed during the fighting, an experience that affected him deeply. His wartime memories, including the loss of close friends, are often discussed alongside the themes of companionship, endurance, and devastated landscapes in his later fiction.

The war did not provide a simple one-to-one source for particular characters or events in Middle-earth. Tolkien rejected overly literal readings of his work, but his military service was an important part of his biography and the historical context in which he began developing his mythology.
