G. le M. (George Le Mesurier) Gretton

George Le Mesurier Gretton, often cited as G. le M. Gretton, was a British author known for military history. Contemporary reference material also identifies him as a barrister: Men-at-the-Bar records that he was a student of the Middle Temple in 1873 and was called to the bar in 1876.

He is chiefly associated with The Campaigns and History of the Royal Irish Regiment from 1684 to 1902, a substantial regimental history later issued in 1911. The title’s military focus, together with later catalog records that style him Lieutenant-Colonel G. Le M. Gretton, suggest a career shaped by both service and historical research.

Reliable online information about his personal life appears to be quite limited, and I could not confirm a suitable portrait from the pages I checked. Even so, his surviving work stands as a useful example of early 20th-century regimental history: detailed, documentary in spirit, and clearly written for readers who wanted the story of a regiment preserved in full.
