Known for a single memorable work tied to the First World War, this writer helped bring the story of the Ulster Division to print after its original compiler was killed in action. Her surviving record is slim, but that one book has kept her name in military history and reprint catalogs.

Dorothy Gage Samuels is credited as co-author of With the Ulster Division in France: A Story of the 11th Battalion Royal Irish Rifles (South Antrim Volunteers), From Bordon to Thiepval. Public catalogs such as Project Gutenberg and bookseller listings consistently associate her with that title, and no other clearly documented books turned up in the sources reviewed.
The book itself explains why it exists: Captain Arthur Purefoy Irwin Samuels had gathered detailed notes and records while serving with the Ulster Division, but he was killed in action on September 24, 1916 before he could complete the project. Dorothy Gage Samuels is named alongside him as author, suggesting she helped shape or prepare the material for publication after his death.
Beyond that, reliable biographical detail is hard to confirm. No solid source located here provided a fuller public life story, major bibliography, or verified portrait, so she remains a somewhat elusive figure whose reputation rests mainly on preserving an important wartime account.
