Ambrose Bierce dates the preface of Tales of Soldiers and Civilians for this day, although it will not actually be issued (in San Francisco) until 1892. It includes "An Occurrence at Owl Creek Bridge", one of his best known works.
The book is divided into two segments—Soldiers and Civilians. Within these short stories, Bierce's uses Roman numerals to demarcate segments.
