Boyd, Belle (1843–1900), a Confederate spy in the Civil War. She was born in Martinsburg, Virginia (now West Virginia). She told of her life in a colorful but perhaps exaggerated book, Belle Boyd in Camp and Prison (1865). She said she gave General “Stonewall" Jackson valuable information in his Shenandoah Valley campaign of 1862. Belle was twice imprisoned by the North but released for lack of evidence. In 1864 she sailed to England, where she became a successful actress. She went on the New York stage in 1868 and later lectured on her war days.
