The Manassas campaign was a series of military engagements in the Eastern Theater of the American Civil War in 1861.
The Confederate forces in northern Virginia were organized into two field armies. Brigadier General P. G. T. Beauregard was appointed commander of the Confederate Army of the Potomac in northeastern Virginia to defend the rail center of Manassas Junction; while General Joseph E. Johnston commanded the Army of the Shenandoah near Harpers Ferry in the Shenandoah Valley. The Manassas Gap Railroad connected the two forces and allowed for the quick transfer of reinforcements between the two armies. [1] During the months of June and July, Beauregard sent Confederate President Jefferson Davis several proposals for offensive operations into Maryland, involving the various Confederate armies in Virginia, but Davis rejected them for being impractical, saying the Confederates lacked the proper resources to support any of his offensive plans. [2]
Following the Union occupation of Alexandria, Virginia, the Union forces in Virginia were organized into the Department of Northeastern Virginia, commanded by Brigadier General Irvin McDowell, who was ordered to advance on the Confederate national capital of Richmond, Virginia. Meanwhile, Robert Patterson was assigned to command the Department of Pennsylvania and was ordered to tie down Johnston's forces in the northern Shenandoah Valley, preventing him from reinforcing Beauregard. [3] [4] Patterson advanced into the Valley in early June, forcing the evacuation of Harpers Ferry on June 17. Johnston retreated back to the town of Winchester, where he was reinforced by home guard units and local militia, which caused Patterson to think he was outnumbered. During this time, Patterson was having difficulty receiving supplies from Pennsylvania; also his regiments of three–month volunteers were nearing the end of their enlistments and were refusing to stay any longer. The Union {{Commanding General of the United States Army|general–in–chief]], Brevet Lieutenant General Winfield Scott, was pressing him to send his Regular Army units to McDowell's army. [5]
During the months of June and early July, the armies of McDowell and Beauregard engaged in several skirmishes in northeastern Virginia while the Union government and military leadership debated the proper course of action for McDowell to take. Scott favored concentrating a Union army to capture the Mississippi River valley, while McDowell viewed his army as too inexperienced to attack Beauregard yet. Due to Pressure from U.S. President Abraham Lincoln and the Union press, McDowell started his campaign against Manassas Junction on July 17. [6] [7] Johnston received orders the next day to start transferring his army to Manassas Junction to reinforce Beauregard; using the Manassas Gap Railroad, his army arrived on July 20 and 21. [8] The Manassas Campaign would end in a Confederate Victory due to this inexperience. It was this early campaign that would show the North that the Confederacy was not going to be a quick rebellion. [9]
Following the Confederate abandonment of Harpers Ferry on June 15, Johnston sent Colonel Thomas J. Jackson's brigade to establish a camp near the town of Martinsburg, so to both serve as a warning of a Union advance and to delay Patterson's force. On July 2, Patterson crossed the Potomac and advanced on Jackson's position. Outnumbered and outflanked, Jackson fell back slowly, giving time for his supply train to escape before retreating to rejoin Johnston's main army. [10] [11]
McDowell's army arrived at Centreville during the morning of July 18, led by Brigadier General Daniel Tyler's division. Under orders to reconnoiter the Confederate defenses near Blackburn's Ford but not to bring on an engagement, Tyler launched an attack with Colonel Israel B. Richardson's brigade but was repulsed by the brigades of James Longstreet and Jubal Early. The battle ended with an artillery duel which lasted until dark, at which time Tyler withdrew back to Centreville. [12]
Following Tyler's defeat, McDowell decided to attempt an attack on the Confederate left flank. Starting about dawn on July 21, one Union division started a diversionary attack on the Stone Bridge on the Confederate left and two other divisions demonstrated against the Confederate center and right, while two other divisions marched around the Confederate left flank to launch an attack on the Confederate rear. The Union flanking column was spotted and Confederate reinforcements were rushed to Matthew's Hill but were driven back to Henry House Hill. A new Confederate defensive line, using brigades from Johnston's army, was formed along the hill, where they held against repeated Union attacks during the afternoon. A Confederate attack on the Union left flank in the late afternoon forced McDowell to retreat back to the defenses of Washington, D.C. [13]
Davis arrived on the Manassas battlefield soon after the battle ended. Although he attempted to organize a pursuit of the Union army, he was convinced that the Confederate armies were too disorganized to mount an effective pursuit. The dispute between Beauregard and Davis over who was responsible for the failed pursuit resulted in Beauregard's transfer to the Western Theater. [14] [15] In October, Johnston's and Beauregard's commands were merged into the Department of Northern Virginia, with the combined army retaining the name "Army of the Potomac". [16]
Following First Bull Run, McDowell retreated to Centreville and set up a rearguard. At a council of war held after sunset, a majority of officers urged a retreat, which started that night. In August, the Department of Northeastern Virginia was merged with other departments in Maryland to form the Department of the Potomac, commanded by George C. McClellan. McDowell was demoted to commanding a division. [17] Patterson was blamed for allowing Johnston to reinforce Beauregard and was also relieved of command. [18]
The Second Battle of Bull Run or Battle of Second Manassas was fought August 28–30, 1862, in Prince William County, Virginia, as part of the American Civil War. It was the culmination of the Northern Virginia Campaign waged by Confederate Gen. Robert E. Lee's Army of Northern Virginia against Union Maj. Gen. John Pope's Army of Virginia, and a battle of much larger scale and numbers than the First Battle of Bull Run fought on July 21, 1861, on the same ground.
Pierre Gustave Toutant-Beauregard was an American military officer known as being the Confederate General who started the American Civil War at the battle of Fort Sumter on April 12, 1861. Today, he is commonly referred to as P. G. T. Beauregard, but he rarely used his first name as an adult. He signed correspondence as G. T. Beauregard.
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.
The Confederate Army of the Potomac, whose name was short-lived, was under the command of Brig. Gen. P. G. T. Beauregard in the early days of the American Civil War. Its only major combat action was the First Battle of Bull Run. Afterwards, the Army of the Shenandoah was merged into the Army of the Potomac with Gen. Joseph E. Johnston, the commander of the Shenandoah, taking command. The Army of the Potomac was renamed the Army of Northern Virginia on March 14, 1862, with Beauregard's original army eventually becoming the First Corps, Army of Northern Virginia.
The Battle of Chantilly took place on September 1, 1862, in Fairfax County, Virginia, as the concluding battle of the Northern Virginia Campaign of the American Civil War. Thomas J. "Stonewall" Jackson's corps of the Army of Northern Virginia attempted to cut off the line of retreat of the Union Army of Virginia following the Second Battle of Bull Run but was attacked by two Union divisions. During the ensuing battle, Union division commanders Isaac Stevens and Philip Kearny were both killed, but the Union attack halted Jackson's advance.
The following is a list of engagements that took place in 1861 during the American Civil War.
The following is a list of engagements that took place in 1862 during the American Civil War. During the summer and early spring of the year, Union forces gained several successes over the Confederacy, seizing control of Missouri, northern Arkansas, Kentucky, and western Tennessee, along with several coastal areas. Confederate forces defended the capital of Richmond, Virginia, from Union assaults, and then launched counter–offensives into Kentucky and Maryland, both of which end in Union victories.
The Battle of Hoke's Run, also known as the Battle of Falling Waters or Battle of Hainesville, took place on July 2, 1861, in Berkeley County, Virginia as part of the Manassas campaign of the American Civil War. Notable as an early engagement of Confederate Colonel Thomas J. Jackson and his Brigade of Virginia Volunteers, nineteen days before their famous nickname would originate, this brief skirmish was hailed by both sides as a stern lesson to the other. Acting precisely upon the orders of a superior officer about how to operate in the face of superior numbers, Jackson's forces resisted General Robert Patterson's Union forces briefly and then slowly retreated over several miles.
The Battle of Blackburn's Ford took place on July 18, 1861, in the Confederate state of Virginia, as part of the Manassas campaign of the American Civil War. Union general Irvin McDowell's Army of Northeastern Virginia was marching south towards the Confederate capital of Richmond, and encountered the Confederate Army of the Potomac under the command of P. G. T. Beauregard. McDowell sent troops from Daniel Tyler's division to probe the Confederate defenses along Bull Run Creek to locate the Confederate left flank. At Blackburn's Ford, the Union troops attempted to cross but Confederate fire broke up the attack. The repulse at Blackburn's Ford led McDowell to seek to attack the Confederates at a different point along their line, leading to the First Battle of Bull Run three days later.
The Northern Virginia Campaign, also known as the Second Bull Run Campaign or Second Manassas Campaign, was a series of battles fought in Virginia during August and September 1862 in the Eastern Theater of the American Civil War. Confederate General Robert E. Lee followed up his successes of the Seven Days Battles in the Peninsula campaign by moving north toward Washington, D.C., and defeating Maj. Gen. John Pope and his Army of Virginia.
Blackburn's Ford was the crossing of Bull Run by Centreville Road between Manassas and Centreville, Virginia, in the United States. It was named after the original owner of the Yorkshire Plantation, Col. Richard Blackburn, formerly of Yorkshire, England. The land was acquired in 1854 by Wilmer McLean who owned it until 1867.
The Army of the Shenandoah was a field army of the Confederate States Army active during the American Civil War. It was created to defend the Shenandoah Valley of Virginia from Union Army attacks during the early months of the war. The army was transferred to reinforce the Confederate Army of the Potomac at the First Battle of Bull Run, which was the only major engagement of the war it participated in. After the battle, the army was merged into the Army of the Potomac.
The eastern theater of the American Civil War consisted of the major military and naval operations in the states of Virginia, West Virginia, Maryland, and Pennsylvania, the District of Columbia, and the coastal fortifications and seaports of North Carolina.

Henry House Hill is a location near Bull Run in Virginia. Named for the house of the Henry family that sits atop it, the hill begins near the road of Centreville, Virginia, after Gainesville, Virginia, to today's U.S. Route 29, the Warrenton Turnpike. It is a slow, constant rise toward the south over a length of approximately 730 meters. This hill was an important site of the battles of First and Second Bull Run in the American Civil War. The battle raged on the north side of the hill in predominantly open grass country; the south side was relatively closely covered with trees. The hill received its name from Dr. Isaac Henry, who lived with his family in a house on the plateau of the hill. On July 21, 1861, the house was inhabited by his widow, Judith Carter Henry, and their two sons. The 85-year-old woman was bed-ridden and unable to leave the house. Mrs. Henry was mortally wounded when a projectile of the Union artillery crashed through the bedroom wall and tore off one of her feet and inflicted multiple injuries, from which she died later that day.
Philip St. George Cocke was a brigadier general in the Confederate States Army during the first year of the American Civil War. He is best known for organizing the defense of Virginia along the Potomac River soon after the state's secession from the Union. He commanded troops in the Battle of Blackburn's Ford and the First Battle of Bull Run in July 1861 before becoming despondent and committing suicide.
The Centreville Military Railroad was a 5.5-mile (8.9 km) spur running from the Orange and Alexandria Railroad east of Manassas Junction across Bull Run and up the south side of the Centreville Plateau. Built by the Confederate States Army between November 1861 and February 1862, it was the first exclusively military railroad. Ultimately, the Centreville Military Railroad reached a point near a modern McDonald's restaurant on Virginia State Route 28, south of the modern junction with U.S. Route 29 in Virginia.
The Department of Pennsylvania was a large military unit in the Union Army at the outset of the American Civil War. Established on April 27, 1861, its territory consisted of Pennsylvania, Delaware, and all of Maryland not embraced in the Department of Annapolis and the Department of Washington. Its remnants were absorbed into the short-lived Department of the Shenandoah on July 19, 1861, which also absorbed the Department of Maryland on July 25, and on August 24 was merged into the Department of the Potomac.
The 2nd Pennsylvania Infantry Regiment was a Union army regiment that participated in the early part the American Civil War.
