Biography
Belle Boyd was a civilian Confederate intelligence agent imprisoned by Union authorities. In her participant memoir Belle Boyd in Camp and Prison (1865), volume I, chapters X–XI, printed pages 163–205, she describes arrest under War Secretary Stanton’s authority, guarded transfer through Winchester and Martinsburg, and actual confinement in Washington’s Old Capitol Prison. Later chapters describe renewed guarded custody at Martinsburg and transfer to Carroll Prison in Washington, printed pages 260–263. These are separate civilian intelligence detention episodes; intervening liberty or parole is not treated as continuous imprisonment. Her retrospective memoir is evidence of her experience, with partisan commentary attributed to her. This proposal assigns no exact arrest or release days from reconstructed chronology.
