What is the setting (time & place)?

In part 1, we find out that this story is taking place in northern Alabama, in the deep South; more specifically, it takes place on a railroad bridge over a body of water called the Owl Creek. In part 2, the narrator tells us that the main character, Peyton Farquhar, owns a plantation and slaves and that he is "an original secessionist [who is] ardently devoted to the Southern cause." In other words, Farquhar very much supports the Confederacy and wants to maintain the practice of slavery. This tells us that the story is taking place sometime during 1861 and 1865, the years of the Civil War. Farquhar is being hanged for attempting to burn down the Owl Creek bridge in order to disrupt the Northern war effort. The reason for burning down the bridge indicates that the war is still going on, and so we can narrow down the timing to those four years.
