5th Great Britain. Army. Highland Light Infantry. Battalion

This author credit refers not to one individual but to the 5th Battalion of the Highland Light Infantry, a territorial battalion of the British Army whose members and officers were associated with the regimental history The Fifth Battalion Highland Light Infantry in the War 1914–1918. Project Gutenberg lists the author as "Great Britain. Army. Highland Light Infantry. Battalion, 5th", while other editions describe it as written by officers of the battalion.

The Highland Light Infantry was a Scottish regiment of the British Army, and the 5th Battalion formed part of its wider regimental tradition. In the book, the battalion records its own wartime experience during the First World War, creating a narrative shaped by those closest to the events rather than by a later outside historian.

Because this is a corporate or unit author rather than a person, there is no single personal biography to give. What makes the work notable is its firsthand regimental perspective: it stands as a memorial record of service, military movement, and shared memory from one battalion's point of view.
