The letter could be the earliest record of the Angel of Mons and pre-dates Arthur Machen's short story, The Bowmen.
The letter was made public in 1931 in a book.
David Clarke, among others, suggest that Charteris used the Angels of Mons for propaganda purposes and the letter is not considered as authentic.
