Rose O'Neal Greenhow

Rose O'Neal Greenhow was a Confederate spy during the American Civil War. A socialite in Washington, D.C., during the period before the war, she moved in important political circles and cultivated friendships with presidents, generals, senators, and high-ranking military officers including John C. Calhoun and James Buchanan. She used her connections to pass along key military information to the Confederacy at the start of the war. In early 1861, she was given control of a pro-Southern spy network in Washington, D.C., by her handler, Thomas Jordan, then a captain in the Confederate Army. She was credited by Jefferson Davis, the Confederate president, with ensuring the South's victory at the First Battle of Bull Run in late July 1861.
