Book of Elves and Fairies for Story-Telling and Reading Aloud-Frances Jenkins Olcott

The Angels of Mons is a popular legend about a group of angels who supposedly protected members of the British army in the Battle of Mons at the outset of World War I. The story is fictitious, developed through a combination of a patriotic short story by Arthur Machen, rumours, mass hysteria and urban legend, claimed visions after the battle and also possibly deliberately seeded propaganda.
