Who is nelson in the book soldiers heart?

"Soldiers Heart" is a short story by William Faulker. While there are characters named "Nelson" in some of Faulkner's other works, there is no character named "Nelson" in "Soldiers Heart."

The main character in "Soldiers Heart" is "Joe", a young man suffering from shell shock (also known as PTSD) after serving in the Civil War.

Perhaps you're thinking of a different Faulkner work? If you can tell me more about the "Nelson" you're asking about, I might be able to help you identify the correct story.
