Explain how ambrose bierce's use of foreshadowing or flashback influence "an occurrence at owl creek bridge."

"An Occurrence at Owl Creek Bridge" is a short story written by American author Ambrose Bierce that was first published on July 13th, 1890. The author uses foreshadowing or flashback to represent and accentuate the gap between reality and illusion that spreads through out the whole story. Bierce uses this technique to guide the reader through the plot, but also to make sure that the reader is surprised when the final revelation about Farquar is known. By using foreshadowing, the author makes the reader question if what it is being told is part of reality or merely and illusion.
