In Free State of Jones (opening in theaters this weekend), Matthew McConaughey stars as Newt Knight, a defiant farmer who deserted from the Confederate army and led an armed rebellion against the CSA in Jones County, Mississippi. Whether he's a hero or a criminal depends on your personal perspective regarding the Civil War (a/k/a the War of Northern Aggression).
You can watch the first five minutes of the film and find out why Newt Knight decided he could no longer fight for the cause.
