Premise: Nancy Hart Douglas (1846–19??) was a scout, guide, and spy for the Confederacy during the American Civil War. Serving first with the Moccasin Rangers, a pro-Confederate guerrilla group in present-day West Virginia, she later joined the Confederate Army and continued to serve as a guide and spy under General Stonewall Jackson.
Hypothesis: Nancy Hart Douglas became a spy for the Confederacy when she was 22 years old
