Belle Boyd, Secret Agent of the Confederacy

This ardent daughter of Virginia ran many hazards in her zeal to aid the Confederate cause. Back and forth she went from her home at Martinsburg, in the valley, through Federal lines, while Banks, Fremont, and Shields were trying in vain to crush "Stonewall" Jackson and relieve Washington from the bugbear of attack. Early in 1862 she was sent as a prisoner to Baltimore. However, General Dix, for lack of evidence, decided to send her home. This first adventure did not dampen her ardor or stop her activities. Since she was now well known to the Federals, her every movement was watched. In May she started to visit relatives in Richmond, but at Winchester happened to overhear some plans of General Shields. With this knowledge she rushed to General Ashby with information that assisted Jackson in planning his brilliant charge on Front Royal. On May 21st she was arrested at the Federal picket-line. A search showed that she had been entrusted with important letters to the Confederate army. About the 1st of August Miss Boyd was taken to Washington by order of the Secretary of War, incarcerated in the Old Capitol Prison and was afterward sent South.
