What happens at the end of the story "An Occurence at Owl Creek Bridge?

The entire story leads up to the tragic end where Farquhar dies.  The story wanders rather slowly through different events in his life.  Thus, the story is ultimately a flashback, because Farquhar begins by standing on the scaffold.  The end is where he is actually hanged.  His hanging happens when he is in a dreamlike sequence where he is running towards his home and his wife.  One can assume this to be his most recent memory.
