The Civil War was America's bloodiest and most divisive conflict, pitting the Union Army against the Confederate States of America. The war resulted in the deaths of more than 620,000 people, with millions more injured and the South left in ruins.
Confederate Spies in Washington
Located 60 miles south of the Mason-Dixon Line, Washington, D.C. was full of southern sympathizers when the Civil War broke out in 1861. Virginiaβs Governor John Letcher, a former congressman, used his knowledge of the city to set up a nascent spy network in the capital in late April 1861, after his state seceded but before it officially joined the Confederacy. Two of the most prominent early recruits were Thomas Jordan, a West Point graduate stationed in Washington before the war, and Rose OβNeal Greenhow, an openly pro-South widow and socialite who was friendly with a number of northern politicians, including Secretary of State William Seward and Massachusetts Senator Henry Wilson.
In July 1861, Greenhow sent coded reports across the Potomac to Jordan (now a volunteer in the Virginia militia) concerning the planned Federal invasion. One of her couriers, a young woman named Bettie Duvall, dressed as a farm girl in order to pass Union sentinels on the Chain Bridge leaving Washington, then rode at high speed to Fairfax Courthouse in Virginia to deliver her message to Confederate officers stationed there. Confederate General P.G.T. Beauregard later credited the information received from Greenhow with helping his rebel army win a surprise victory in the First Battle of Bull Run (Manassas) on July 21.
Confederate Signal Corps and Secret Service Bureau
The Confederate Signal Corps, which operated the semaphore system used for communicating vital information between armies on the field, also set up a covert intelligence operation known as the Secret Service Bureau. Headed by William Norris, the former Baltimore lawyer who also served as chief signal officer for the Confederacy, the bureau managed the so-called βSecret Line,β an ever-changing system of couriers used to get information from Washington across the Potomac and Rappahannock Rivers to Confederate officials in Richmond. The Secret Service Bureau also handled the passing of coded messages from Richmond to Confederate agents in the North, Canada and Europe.
A number of Confederate soldiers, especially cavalrymen, also acted as spies or βscoutsβ for the rebel cause. Among the most famous were John Singleton Mosby, known as the βGray Ghost,β who led guerrilla warfare in western Virginia through the latter years of the war, and especially J.E.B. Stuart, the celebrated cavalry officer whom General Robert E. Lee called βthe eyes of the army.β
Union Spies: Allan Pinkertonβs Secret Service
Allan Pinkerton, the founder of his own detective agency in Chicago, had collected intelligence for Union General George B. McClellan during the first months of the Civil War, while McClellan led the Department of Ohio. When President Abraham Lincoln summoned McClellan to Washington late that summer, the general put the detective in charge for intelligence for his Army of the Potomac, and Pinkerton set up the first Union espionage operation in mid-1861. Calling himself E.J. Allen, Pinkerton built a counterintelligence network in Washington and sent undercover agents to ingratiate themselves in the Confederate capital of Richmond. Unfortunately, Pinkertonβs intelligence reports from the field during 1862βs Peninsula Campaign consistently miscalculated Confederate numbers at twice or three times their actual strength, fueling McClellanβs repeated calls for reinforcements and reluctance to act.
Though he called his operation the U.S. Secret Service, Pinkerton actually worked only for McClellan. Union military intelligence was still decentralized at the time, as generals (and even President Lincoln) employed their own agents to seek out information and report back to them. Another prominent Union intelligence officer was Lafayette C. Baker, who worked for the former Union General in Chief Winfield Scott and later for Secretary of War Edwin Stanton. The brave but ruthless Baker was notorious for rounding up Washingtonians suspected of having southern sympathies; he later directed the manhunt for John Wilkes Booth, the actor and Confederate sympathizer who shot and killed Lincoln at Fordβs Theatre in April 1865.
