"An Occurrence at Owl Creek Bridge" (1890) is a short story by American writer and Civil War veteran Ambrose Bierce, described as "one of the most famous and frequently anthologized stories in American literature". It was originally published by The San Francisco Examiner on July 13, 1890, and was first collected in Bierce's book Tales of Soldiers and Civilians (1891). The story is set during the American Civil War and is known for its irregular time sequence and twist ending. Bierce's abandonment of strict linear narration in favor of the internal mind of the protagonist is an early example of the stream of consciousness narrative mode.
