What was the title of J.R.R. Tolkien’s first published poem?

J.R.R. Tolkien’s first published poem was “The Battle of the Eastern Field.”

The poem appeared in 1911 in the King Edward’s School Chronicle, the school magazine of Tolkien’s Birmingham school. It reflects his early interest in verse and heroic subject matter, interests that continued throughout his academic and creative life.

This poem predates Tolkien’s famous Middle-earth books by decades. It is therefore different from later collections such as The Adventures of Tom Bombadil and from poems published in professional venues. Bibliographies may organize Tolkien’s early works differently, but this school-magazine publication is commonly identified as his first published poem.
