This is the incredible true story of Sarah Emma Edmonds, who dressed as a man and fought in the Civil War. When she was 19, Sarah cut her hair, donned her brother's clothes, and fled from Canada, where her father wanted her to marry an elderly gentleman. In the U.S., she went by the name Frank Thompson and joined the Army to fight the Confederates. She was a nurse working on the battlefield when, because of her heroism, she was asked to serve as a spy. At her death, Edmonds was buried in a military cemetery, in a plot reserved for Civil War veterans--the only woman to have this honor.
