Ambrose Bierce's use of flashback influences "An Occurrence at Owl Creek Bridge" by providing crucial background information about the protagonist, Peyton Farquhar, and his present circumstances. Through the flashback, readers learn about Farquhar's strong desire to serve in the Confederate army and his subsequent plan to sabotage Owl Creek Bridge. This information builds tension and sets the stage for the events that follow, foreshadowing the tragic outcome of Farquhar's actions. This technique also adds depth to the story and allows readers to understand Farquhar's motivations and the consequences he ultimately faces.
