Rose O'Neal Greenhow was born in Maryland in 1813 and grew up around war, wanting to play a role despite her mother saying women could not be involved. As a 27-year-old, she discovered a group of female spies and moved to New York to begin spying for the Confederacy by cooking for Union men while gathering military intelligence. She had a successful 15-year spy career, even writing a book about it, but was eventually sentenced to house arrest after being discovered. In 1864, while attempting to return home on a ship, she drowned when her rowboat capsized while trying to avoid a Union gunboat, dragged down by gold she received for her book.
