Battle of the American Civil War
The Battle of Fairfax Court House was fought during the Gettysburg Campaign of the American Civil War between two cavalry detachments from the Union Army of the Potomac, commanded by General Joseph Hooker, and the Confederate Army of Northern Virginia, commanded by General Robert E. Lee.
The Confederate cavalry leader General J.E.B. Stuart was keen to restore his prestige after two humiliating encounters with Union cavalry, and as the main body crossed the Potomac into Maryland, he received permission to detach three brigades and ride around the entire Union army to gather supplies and intelligence, and damage lines of communication.
At Fairfax Court House, Virginia, on June 27, one of Stuart’s brigades, led by Brigadier General Wade Hampton, was surprised by a small detachment of the 11th New York Cavalry under Major Remington, which initially drove them into the woods, but were so heavily outnumbered that they had to retreat. Although technically a Confederate win, this small engagement had a major impact on the outcome of Gettysburg, since it delayed Stuart’s arrival, depriving Lee of essential knowledge of the enemy’s whereabouts.
Background.
Plan to invade the North.
On the night of May 5–6, 1863, after the Army of the Potomac commanded by Major General Joseph Hooker had been defeated at the Battle of Chancellorsville (April 30, 1863 to May 6, 1863), in Spotsylvania County, Virginia by the General Robert E. Lee's Army of Northern Virginia, Hooker withdrew his forces to positions north of the Rappahannock River, mainly in the vicinity of Falmouth, Virginia. Lee's army remained just to the south of the Rappahannock in the Fredericksburg, Virginia area after the battle.
Meanwhile, in Mississippi, Union Major General Ulysses S. Grant was closing in on a Confederate army at Vicksburg, Mississippi. Loss of Vicksburg would give the Union control of the Mississippi River and effectively cut off Confederate territory west of the Mississippi from the rest of the Confederacy. Leaders of the Confederate government, Confederate President Jefferson Davis and Confederate States Secretary of War James A. Seddon wanted to relieve the pressure on Vicksburg, possibly by sending reinforcements from Virginia to Mississippi or to Tennessee in order to divert attention of Union forces from Vicksburg.
In meetings with Davis and Seddon from May 14, 1863 to May 17, 1863 and on May 26, 1863, Lee proposed to relieve the pressure in Mississippi by diverting Union Army attention to an invasion of the North from Virginia. This also would spare Virginia from further campaigning that summer, allow the Army of Northern Virginia to live off the land in the North and to threaten major cities, such as Philadelphia, Baltimore and Washington, D.C., in order to weaken Northern support for the war and possibly even to obtain foreign recognition of the Confederacy. Davis and Seddon, along with Davis's entire cabinet, except Postmaster-General John Reagan of Texas, agreed upon Lee's plan at these meetings. However, further correspondence was exchanged, which made it appear to some later historians that Davis's full approval did not come until May 31. On the other hand, historian Stephen W. Sears states that the further correspondence only concerned Lee's difficulty with D. H. Hill concerning reinforcements and not the plan to invade the North and that Lee began to get his force ready to move north on May 17.
Lee completed a reorganization of his army by June 1, 1863 and began preparations to move to Virginia's Shenandoah Valley and then into Maryland and Pennsylvania. By June 2, 1863, Lee had intelligence that Union forces along the Virginia coast and on the Virginia Peninsula were not contemplating a move against Richmond, Virginia, the Confederacy's capital and that Hooker was not prepared to make another strike across the Rappahannock.
Beginning of the Gettysburg Campaign.
The Confederate Gettysburg Campaign began on June 3, 1863 with the Second Corps, Army of Northern Virginia, under its new commander, Lieutenant General Richard S. Ewell, moving northwest from the Fredericksburg area to Culpeper Court House, Virginia. By the next day, Hooker learned of the Confederate movement but did not know whether Lee was attempting to move north or to attack Hooker's right flank or whether the Confederates were moving their infantry or just cavalry. Hooker proposed to attack Lieutenant General A. P. Hill's Third Corps at Fredericksburg but President Abraham Lincoln and Union Army General-in-Chief Henry Halleck thought that the plan was too risky and would enable Lee to turn his force at Culpeper to attack Hooker's flank, possibly while Hooker's men were engaged in crossing the Rappahannock. Hooker gave up the idea.
On June 6, 1863, Union Brigadier General John Buford informed Hooker that Lee's "movable" force, consisting of six brigades of cavalry, was at Culpeper. Buford did not know about the presence of Ewell's Second Corps and two of James Longstreet's First Corps divisions at Culpeper.
Battle of Brandy Station.
On June 7, acting on Buford's intelligence, Hooker ordered Major General Alfred Pleasonton to take his entire cavalry corps and 3,000 infantrymen, a combined force of about 11,000 men including artillerymen, across the Rappahannock River near Brandy Station, Virginia and "disperse and destroy" the Confederate force at Culpeper. At dawn on June 9, 1863, Pleasonton's force, divided into two wings commanded by Brigadier General John Buford and Brigadier General David McMurtrie Gregg, crossed the Rappahannock at Beverly Ford and Kelly's Ford, about apart. They planned to unite at Brandy Station about from Beverly Ford and from Kelly's Ford and then to move west to Culpeper. Buford's wing drove the Confederate pickets from Beverly Ford and surprised the Confederate cavalry camped nearby around Fleetwood Hill, where Stuart had his headquarters, and Brandy Station. The Battle of Brandy Station, the largest cavalry battle of the war, continued until late afternoon with the Confederates ultimately holding Fleetwood Hill. With Confederate infantry approaching the area, Pleasonton made an orderly withdrawal across the Rappahannock. Stuart called the battle a victory but he was subjected to criticism for being surprised and for the losses inflicted on his men by Pleasonton's force. To Stuart's chagrin, for the first time in the war, the Union cavalry came out of a battle with the Confederate cavalry on roughly even terms.
Troop movements and cavalry actions.
Between June 9 and June 15, 1863, Lee contended with Davis and Seddon, and with the commander of Confederate forces in North Carolina and Southeast Virginia, Major General Daniel Harvey Hill, about the number and veteran status of the units to be left behind to guard Richmond and the coastal areas of Virginia and North Carolina. On June 15, Lee began to concentrate his entire army for the offensive. He had already ordered Ewell to proceed with the Second Corp to the Shenandoah Valley on June 10.
After the Battle of Brandy Station, Hooker was persuaded by Pleasonton that Confederate infantry were at Culpeper and began to move his corps to the west, eventually spreading the Army of the Potomac over a line from Fredericksburg to Beverly Ford. On June 13, Hooker heard that the First Corps and Second Corps of the Army of Northern Virginia were headed toward the Shenandoah Valley. On June 14, he ordered the right wing of his army to concentrate at Manassas Junction, Virginia and the left wing to go to Dumfries, Virginia after withdrawing government property from depots north of Fredericksburg, especially the base at Aquia Creek. Hooker moved his headquarters to Dumfries and then to Fairfax Station and then to Fairfax Court House. By leaving the Fredericksburg line, Hooker enabled Lee to order Hill to go to Culpeper and Longstreet to proceed to the Shenandoah Valley without concern that Hooker would try to cross the Rappahannock and make a strike toward Richmond.
Two Confederate cavalry brigades under William E. Jones ("Grumble" Jones) and Wade Hampton III screened the movement of A. P. Hill's Corps to Culpeper. The Confederate and Union forces, mostly cavalry, fought daily in the Loudoun Valley area between the Blue Ridge Mountains and the Bull Run Mountains during the week after June 17, 1863 as the two armies tried to learn each other's positions and movements or to prevent their opposition from gathering such information about their own forces. Although the Confederates kept the Union cavalry east of the Blue Ridge, Pleasanton and Gregg concluded that only Confederate cavalry was east of the Blue Ridge when in fact Longstreet's corps was spread out east of the mountains for some days that week.
Battle of Upperville.
With Hooker's permission, on June 21, Pleasonton left two infantry brigades at Middleburg to guard his line of communications and took five cavalry brigades and Colonel (United States) Strong Vincent's infantry brigade to attack Stuart's five cavalry brigades near Upperville, Virginia. At the Battle of Upperville, Pleasonton's force drove Stuart's five brigades from the town and into Ashby's Gap. Pleasonton was satisfied with this result and did not try to push Stuart across the mountains. Stuart had kept Pleasonton from finding the Confederate infantry. Near nightfall, however, Brigadier General John Buford's scouts rode up a nearby ridge and spied Confederate infantry camps in the Shenandoah Valley. The minor Union victory at Upperville which resulted in the capture of one or two Confederate artillery pieces and about 250 Confederate prisoners also resulted in gathering some useful intelligence about the disposition of part of Lee's infantry The action also delayed the march of two infantry divisions of Lee's army in order for the Confederates to be sure to hold Ashby's Gap and to have a force available at Shepherdstown, West Virginia if Union troops moved toward the Shenandoah Valley and were able to break through. Stuart again came in for criticism in Southern newspapers for being surprised and defeated at Upperville.
Lee soon learned that Pleasonton had withdrawn to Aldie, Virginia. He then knew he could leave the heavily reinforced positions in Virginia and hasten his movement into Maryland and Pennsylvania. Ewell's corps, with Albert G. Jenkins's cavalry brigade were to march toward the Susquehanna River to gather food and supplies. Lee ordered Brigadier General John D. Imboden to lead his cavalry brigade across the Potomac to join Ewell's corps if opportunity offered, but Imboden decided he did not have that opportunity and stayed behind.
Beginning of Stuart's ride.
Stuart now sought to take a useful role in the campaign and perhaps, according to some historians, to redeem his reputation and to secure the glory of another ride around the Union Army. On June 22, Lee gave Stuart discretionary orders for his movement to Pennsylvania with the important point being: "If you find that he [the enemy] is moving northward, and that two brigades can guard the Blue Ridge and take care of your rear, you can move with the other three into Maryland, and take position on General Ewell's right." Lee wrote to Stuart again on June 23 in an apparent effort to clarify his orders as follows: "You will, however, be able to judge whether you can pass around their Army without hindrance, doing them all the damage you can, and cross the river east of the mountains. In either case, after crossing the river, you must move on and feel the right of Ewell's troops." Lee's orders did not give Stuart a specific route to follow. Confederate Colonel Edward Porter Alexander, chief of artillery of Longstreet's corps, stated "Stuart made to Lee a very unwise proposition, which Lee more unwisely entertained."
Major John S. Mosby, scouting for Stuart with a small group of partisan rangers, told Stuart that Stuart could cut through the separated Union corps, cross the Potomac at Seneca Ford, northwest of Washington, D.C., and disrupt Hooker's communications and supplies, possibly even divert his army toward the defense of Washington. Stuart was eager to restore his reputation after being surprised and evenly fought at Brandy Station and Upperville. After Mosby reported that Hooker did not seem to be moving, on June 24 Stuart used the discretion in his orders to follow Mosby's advice and attempt to ride through and around the Union Army and, as he said thereafter, to meet Ewell at York, Pennsylvania. Historian Edwin B. Coddington said the directive to damage the Union forces on the way was an invitation to delay. Taking his three most experienced brigades under Brigadier Generals Wade Hampton, III and Fitzhugh Lee and Colonel John R. Chambliss, Jr. in temporary command of W.H.F.
