The names you might know, the story you didn’t.

Amid the Civil War, there were a few daring individuals who used their cunning and bravery to spy for either the Union or Confederate forces.
These spies often took huge risks to gain valuable information and sometimes even helped turn the tide of battle.
Here are seven of the most shocking and influential Civil War spies who were integral in changing the course of the war.
7- Belle Boyd — Cleopatra of the Secession

Belle Boyd, also known as “Cleopatra of the Secession,” was a daring Confederate spy during the Civil War.
Born in Martinsburg, Virginia in 1844, Belle Boyd quickly gained notoriety as a passionate pro-southern rebel who often smuggled documents and letters across enemy lines.
In 1861, after a Union officer insulted her mother, Boyd famously shot the officer dead, then fled to the south, where she was hailed as a hero.
Afterward, Boyd became an informant for the Confederates, relaying messages and details about the Union army’s movements and strategies.
Boyd was eventually arrested by the Union army in 1862, but soon escaped prison and continued to serve as a spy for the Confederacy.
She even managed to smuggle sensitive information out of a Union prison camp in Washington D.C. in 1863.
After the war, Boyd toured the country with a speaking show and wrote a memoir about her experiences as a spy. Today, her legacy as a daring Confederate spy lives on.
6- Elizabeth Van Lew — Crazy Bet

Elizabeth Van Lew was a Virginia native and a Union sympathizer during the Civil War. She used her position in the Confederate capital of Richmond to aid the Union war effort and her cunning espionage tactics earned her the nickname “Crazy Bet”.
Van Lew began her service to the Union cause by gathering intelligence and sending it to the Union Army via secret lines of communication.
She had a network of spies who reported to her, and she also helped supply Union soldiers with food and supplies.
In addition to being an intelligence asset, Van Lew was also adept at garnering public support for the Union.
She helped free Union prisoners of war, set up secret schools for African American children, and provided medical care to both Union soldiers and civilians.
Her spy activities were eventually discovered by Confederate authorities, and Van Lew was arrested and held prisoner in 1863. After her release, she continued to serve the Union until the war ended.
Van Lew’s contributions to the Union war effort were crucial, and her dedication and bravery are an inspiring reminder of the power of loyalty and courage during difficult times.
5- John Scobell — Double Agent

John Scobell was a former slave who became a double agent during the American Civil War. His espionage work earned him the distinction of being one of the most successful spies in the Union Army.
He provided valuable information to both the Union and Confederate forces, often switching sides to gain intelligence from both sides.
Scobell was born in 1879 and worked as a slave in South Carolina until he escaped to Philadelphia. He offered his services as a spy to Major General Benjamin Butler, Commander of the Union forces in Virginia.
John was hired for his knowledge of the local terrain and customs. Scobell’s mission was to travel between Union and Confederate camps and report on their activities and strength.
He was able to do this without suspicion as he was a local African-American man who was known to both sides. During his missions, he gathered important intelligence such as troop movements and supplies, helping the Union to plan strategic maneuvers.
He also reported on how the Confederate forces were treating African-American slaves, which helped inform the Emancipation Proclamation.
For his efforts, Scobell received commendations from General Butler and President Lincoln himself.
Scobell’s service continued until the end of the war when he eventually returned to South Carolina and was freed. He passed away in 1955 at the age of 75.
John Scobell was an invaluable asset to the Union during the Civil War and his contribution is remembered to this day. His ability to provide accurate intelligence from both sides of the conflict was an invaluable asset and was instrumental in securing Union victory.
4- Mary Bowser — Slave And Spy
Mary Bowser was born into slavery, yet she would go on to become one of the most daring and successful Union spies of the Civil War.
Her real name was Eliza Jane, but she is most commonly referred to by her pseudonym, Mary Bowser. In 1856, she and her family were freed by their owner, John Van Lew.
After the Van Lews moved to Richmond, Virginia in 1861, they invited Mary to live with them and join their cause as a Union spy. Mary disguised herself as a slave, often taking on menial tasks like dusting the furniture and washing dishes to gain access to Confederate military plans.
She would then memorize the plans and report back to the Union. In addition, she posed as a seamstress at the Confederate White House in Richmond, where she managed to gain access to President Jefferson Davis’ private letters.
Throughout her spying, Mary was able to move around without suspicion as Confederate soldiers believed that slaves were incapable of understanding such intelligence matters.
Mary’s courage and dedication saved countless Union lives and ensured a victory for the North. Unfortunately, after the war ended in 1865, Mary’s story faded away and no one knows what happened to her.
Despite this mystery, Mary’s incredible service to the Union during the Civil War will never be forgotten.
3- Harriet Tubman — Moses of Her People

Harriet Tubman is one of the most famous figures in American history, and her exploits as a spy during the Civil War are no less impressive.
Born into slavery in 1822, Tubman escaped in 1849 and soon began aiding other slaves in their escape through the Underground Railroad.
During the Civil War, Tubman was recruited by Union forces as a spy and scout. She infiltrated Confederate lines multiple times, gathering information on enemy positions and movements.
Her most famous mission came in 1863 when she led Union troops on a successful raid of the Combahee River, liberating hundreds of slaves in the process. Her efforts earned her the nickname “Moses of Her People.”
Tubman also served as a nurse and cook for the Union forces, caring for wounded soldiers and helping to raise morale. She continued to fight for civil rights after the war ended, becoming an influential advocate for women’s rights.
Her incredible story of courage and determination has been immortalized in books and films, making her one of the most iconic figures of the Civil War era.
2- Thomas Haines Dudley — Confederate soldier

Thomas Haines Dudley was an extraordinary Civil War spy. He was a free black man, and he was recruited by the Union Army.
Dudley proved to be a valuable asset to the Union. His main job was to collect intelligence from within Confederate lines and deliver it back to the Union.
He would disguise himself as a Confederate soldier and blend in with the crowd, often carrying false papers that allowed him to move about freely.
Dudley was also responsible for delivering important messages from the Union Army to its allies in the South. These messages often contained information that could help turn the tide of battle.
On one occasion, he successfully delivered an order for the surrender of Fort Donelson. Dudley’s efforts did not go unnoticed, and in 1863 he was officially commissioned as a first lieutenant in the Union Army.
He served with distinction and eventually retired in 1865 after the war had ended. Dudley’s bravery and loyalty to the Union were instrumental in helping to bring the Civil War to an end. His legacy will live on as one of the most effective spies of the Civil War era.
1- Timothy Webster — Self-taught Detective And Investigator
Timothy Webster is remembered as one of the most successful Civil War spies of his time. He was born in 1822, and as a young man, he became a self-taught detective and investigator.
His skills earned him a job as a Pinkerton agent, which would eventually lead him to his role in the Civil War. At the start of the war, Webster was recruited by Allan Pinkerton, the head of Union intelligence.
In this role, he served as a courier and secret agent. He made his way across enemy lines to gather valuable information on Confederate plans and military movements.
On one such mission, he posed as a Southern sympathizer to gain access to General Beauregard’s forces in Manassas.
It was this mission that gained him the most notoriety, as he had successfully outsmarted Confederate agents by passing through three different lines of pickets without detection.
On other occasions, Webster operated undercover as a blacksmith or wagon driver, passing intelligence back to Union commanders.
In addition to his espionage work, he also performed reconnaissance missions for the Union army. He played an instrumental role in helping plan General McClellan’s campaign against Richmond in 1862.
Unfortunately, Webster’s luck ran out in April 1863. On a mission to gather intelligence from Confederate cavalry in South Carolina, he was captured by Confederate soldiers and sentenced to death for espionage.
However, due to public outcry over his execution, his sentence was later commuted to life imprisonment in Georgia’s Camp Lawton prison camp.
Though he was never released from prison and died there in 1864, Timothy Webster’s contributions to the Union cause were immense.
He remains an example of how brave men and women risked their lives during the Civil War to help ensure victory for the Union.
