Answer:
The ending of “An Occurrence at Owl Creek Bridge” has drawn many reactions from critics. Some believe the ending is contrived and more appropriate for a thriller, suspense, or mystery tale than for a literary work. Others see the ending as Bierce’s attempt to transform the traditional conventions of narration. The story of Farquhar’s execution, like a traditional story, follows a logical order: from introduction to development to conclusion. Bierce’s “trick” is that the conclusion is not what it seems. Although the story does not end after the first section, Farquhar’s life does, extended for a few agonizing seconds as he swings from the end of the rope. By adding the third section, Bierce calls into question the essential nature of a story’s resolution. Endings, his story reveals, can often be unresolved or manipulated. They do not always have to be tidy, as they often are in more traditional prose.
