Allan Pinkerton was a Scottish-American cooper, abolitionist, detective, and spy, best known for creating the Pinkerton National Detective Agency in the United States and his claim to have foiled a plot in 1861 to assassinate president-elect Abraham Lincoln. During the Civil War, he provided the Union Army – specifically General George B. McClellan of the Army of the Potomac – with military intelligence, including extremely inaccurate enemy troop strength numbers. After the war, his agents played a significant role as strikebreakers – in particular during the Great Railroad Strike of 1877 – a role that Pinkerton men would continue to play after the death of their founder.
The First Battle of Bull Run, called the Battle of First Manassas by Confederate forces, was the first major battle of the American Civil War. The battle was fought on July 21, 1861, in Prince William County, Virginia, just north of the city of Manassas and about thirty miles west-southwest of Washington, D.C. The Union Army was slow in positioning themselves, allowing Confederate reinforcements time to arrive by rail. Each side had about 18,000 poorly trained and poorly led troops. The battle was a Confederate victory and was followed by a disorganized post-battle retreat of the Union forces.
Rose O'Neal Greenhow was a famous Confederate spy during the American Civil War. A socialite in Washington, D.C., during the period before the war, she moved in important political circles and cultivated friendships with presidents, generals, senators, and high-ranking military officers including John C. Calhoun and James Buchanan. She used her connections to pass along key military information to the Confederacy at the start of the war. In early 1861, she was given control of a pro-Southern spy network in Washington, D.C., by her handler, Thomas Jordan, then a captain in the Confederate Army. She was credited by Jefferson Davis, the Confederate president, with ensuring the South's victory at the First Battle of Bull Run in late July 1861.
Maria Isabella Boyd, best known as Belle Boyd was a Confederate spy in the American Civil War. She operated from her father's hotel in Front Royal, Virginia, and provided valuable information to Confederate General Stonewall Jackson in 1862.

Grant's intelligence chief in the Western Theater. He served in several notable assignments, including command of the XVI Corps during the Atlanta Campaign.
The Maryland campaign occurred September 4–20, 1862, during the American Civil War. The campaign was Confederate General Robert E. Lee's first invasion of the North. It was repulsed by the Army of the Potomac under Maj. Gen. George B. McClellan, who moved to intercept Lee and his Army of Northern Virginia and eventually attacked it near Sharpsburg, Maryland. The resulting Battle of Antietam was the bloodiest day of battle in American history.
The Chickamauga campaign of the American Civil War was a series of battles fought in northwestern Georgia from August 21 to September 20, 1863, between the Union Army of the Cumberland and Confederate Army of Tennessee. The campaign started successfully for Union commander William S. Rosecrans, with the Union army occupying the vital city of Chattanooga and forcing the Confederates to retreat into northern Georgia. But a Confederate attack at the Battle of Chickamauga forced Rosecrans to retreat back into Chattanooga and allowed the Confederates to lay siege to the Union forces.
The Confederate Secret Service refers to any of a number of official and semi-official secret service organizations and operations conducted by the Confederate States of America during the American Civil War. Some of the organizations were under the direction of the Confederate government, others operated independently with government approval, while still others were either completely independent of the government or operated with only its tacit acknowledgment.
Black Dispatches was a common term used among Union military men in the American Civil War for intelligence on Confederate forces provided by African Americans, who often were slaves aiding the Union forces. They knew the terrain and could move within many areas without being noticed; their information represented a prolific and productive category of intelligence obtained and acted on by Union forces throughout the Civil War.
During the American Civil War, the State of Ohio played a key role in providing troops, military officers, and supplies to the Union army. Due to its central location in the Northern United States and burgeoning population, Ohio was both politically and logistically important to the war effort. Despite the state's boasting a number of very powerful Republican politicians, it was divided politically. Portions of Southern Ohio followed the Peace Democrats and openly opposed President Abraham Lincoln's policies. Ohio played an important part in the Underground Railroad prior to the war, and remained a haven for escaped and runaway slaves during the war years.
Aaron Van Camp was an espionage agent for the Confederate States of America during the American Civil War. He and his son Eugene B. Van Camp were members of the Rose O'Neal Greenhow Confederate spy ring, which in 1861 was broken up by Allan Pinkerton, head of the newly formed Secret Service.

Mary Richards, also known as Mary Jane Richards Garvin and possibly Mary Bowser, was a Union spy during the Civil War. She was possibly born enslaved from birth in Virginia, but there is no documentation of where she was born or who her parents were. By the age of seven, she was enslaved by the household of Elizabeth "Bet" Van Lew, in Richmond, Virginia. The Van Lew family sent Richards to school somewhere in the north, and then to Liberia through the American Colonization Society. Richards returned to Richmond shortly before the outbreak of the American Civil War, where she was one of many black and white Richmond residents who collected and delivered military information to the United States Army under the leadership of Elizabeth Van Lew.
Hattie Lawton, also known as Hattie H. Lawton, Hattie Lewis, and Hattie Lewis Lawton was an American detective, who worked for Allan Pinkerton, of the Pinkerton Detective Agency. Lawton may have been born around 1837, although most details of her life, before and after the American Civil War, are unknown. "[Hattie] Lawton was part of Pinkerton's Female Detective Bureau, formed in 1860 to 'worm out secrets' by means unavailable to male detectives."
