Origin

The battle flag of the Army of Northern Virginia, designed by William Porcher Miles

The name Army of Northern Virginia referred to its primary area of operation, which was typical of most Confederate States Army names. The Army originated as the Army of the Potomac, which was organized on June 20, 1861, from all operational forces in Northern Virginia. On July 20 and July 21, the Army of the Shenandoah and forces from the District of Harpers Ferry were added. Units from the Army of the Northwest were merged into the Army of the Potomac between March 14 and May 17, 1862. The Army of the Potomac was renamed the Army of Northern Virginia on March 14. The Army of the Peninsula was merged into it on April 12, 1862.^[2]

Robert E. Lee's biographer, Douglas S. Freeman, asserts that the army received its final name from Lee when he issued orders assuming command on June 1, 1862.^[3] However, Freeman does admit that Lee corresponded with Joseph E. Johnston, his predecessor in army command, prior to that date and referred to Johnston's command as the Army of Northern Virginia. Part of the confusion results from the fact that Johnston commanded the Department of Northern Virginia (as of October 22, 1861) and the name Army of Northern Virginia can be seen as an informal consequence of its parent department's name. Jefferson Davis and Johnston did not adopt the name, but it is clear that the organization of units as of March 14 was the same organization that Lee received on June 1, and thus it is generally referred to today as the Army of Northern Virginia, even if that is correct only in retrospect.

In addition to Virginians, it included regiments from all over the Confederacy, some from as far away as Georgia, Texas, and Arkansas. One of the most well known was the Texas Brigade, made up of the 1st, 4th, and 5th Texas, and the 3rd Arkansas, which distinguished themselves in numerous battles, such as during their fight for the Devil's Den at the Battle of Gettysburg.

Beauregard's command

General P. G. T. Beauregard

The first commander of the Army of Northern Virginia was General P. G. T. Beauregard, under its previous name, the Confederate Army of the Potomac, from June 20 to July 20, 1861. His forces consisted of six brigades, with various militia and artillery from the former Department of Alexandria. During his command, Beauregard is noted for creating the battle flag of the army, which came to be the primary battle flag for all corps and forces under the Army of Northern Virginia. The flag was designed due to confusion during battle between the Confederate Stars and Bars flag and the flag of the United States. Beauregard continued commanding these troops as the new First Corps under Gen. J. E. Johnston as it was joined by the Army of the Shenandoah on July 20, 1861, when command was relinquished to General J. E. Johnston. The following day this army fought its first major engagement in the First Battle of Manassas.

Johnston's command

General Joseph E. Johnston

With the merging of the Army of the Shenandoah, General Joseph E. Johnston took command from July 20, 1861, until May 31, 1862.

Smith's temporary command

Gustavus Woodson Smith

Maj. Gen. Gustavus Woodson Smith commanded the ANV on May 31, 1862, following the wounding of Gen. J. E. Johnston during the Battle of Seven Pines. With Smith seemingly having a nervous breakdown, President Jefferson Davis drafted orders to place Gen. Robert E. Lee in command the following day.

Lee's command

General Robert E. Lee, commander of the Army of Northern Virginia

On June 1, 1862, General Robert E. Lee, its final and best known leader historically, took command after Johnston was wounded and Smith suffered what may have been a nervous breakdown at the Battle of Seven Pines. William Whiting received permanent command of Smith's division, while Richard Anderson reverted to brigade command. Longstreet served as a wing commander for part of the Seven Days Battles and Anderson had operational command of the division at Glendale.

The cavalry, organized into a division on August 17, 1862, and into a corps on September 9, 1863, was commanded by Maj. Gen. J.E.B. Stuart until May 11, 1864 (the day he was mortally wounded). The cavalry corps was then temporarily split into divisions, but was merged again on August 11, 1864, under command of Lt. Gen. Wade Hampton III. The Reserve Artillery was commanded by Brig. Gen. William N. Pendleton for most of the war.^[2]

During the Seven Days Battles, Lee had eleven separate divisions under his command. Aside from the original core army that had been led by Johnston, there were assorted other commands from the Richmond area and North Carolina, as well as Jackson's Valley Army. The inexperience and poor coordination of the army led to the failure of Lee's plans to destroy the Army of the Potomac. As soon as the Seven Days Battles were over, Lee reorganized his army into two corps commanded by Jackson and Longstreet. He removed several generals who had turned in a less-than-inspiring performance in the Seven Days Battles, including John Magruder and Benjamin Huger.

Jackson had five divisions, the commands of A.P. Hill, Ewell, D.H. Hill, and Winder. Longstreet had six divisions commanded by Richard Anderson (formerly Benjamin Huger's division), Cadmus M. Wilcox, James L. Kemper (each commanding half of Longstreet's former division), John Bell Hood (formerly William Whiting's division), David Rumph Jones, and Lafayette McLaws. D.H. Hill's and McLaws's divisions were left behind in the Richmond area and did not participate in the Northern Virginia campaign. The army was also joined for the Northern Virginia and Maryland Campaigns by Nathan G. Evans's independent South Carolina brigade and a North Carolina brigade led by Brig. Gen Thomas Drayton.

During the Maryland campaign, D.H. Hill rejoined the main army along with Lafayette McLaws. Kemper's division was merged with the division of David R. Jones, a more senior, experienced officer, and Kemper reverted to brigade command. In addition, Robert Ransom commanded two brigades from the Department of North Carolina. At Antietam, Longstreet commanded the divisions of Anderson, McLaws, Jones, Hood, and Ransom while Jackson had the divisions of John R. Jones, Alexander Lawton, A.P. Hill, and D.H. Hill.

The Northern Virginia and Maryland Campaigns still showed numerous defects in the organization and leadership of the Army of Northern Virginia, particularly the high rate of straggling and desertion during the invasion of Maryland. Lee had fewer than 40,000 men on the field at Antietam, the smallest his army would be until the Appomattox Campaign, and the battle was largely fought on autopilot with minimal involvement by the senior officers in the army.

During the Fredericksburg Campaign, Longstreet had the divisions of Anderson, Hood, McLaws, Ransom, and George Pickett, who had just returned to action after months of convalescence from a wound sustained at the Battle of Gaines's Mill.^[4][5] Jackson had the divisions of D.H. Hill, A.P. Hill, Jubal Early, and Elisha Paxton. Robert Ransom's division returned to North Carolina after Fredericksburg. D.H. Hill also departed after quarreling with Lee.

In the Chancellorsville Campaign, Longstreet was sent with Pickett and Hood to the Richmond area. His other two divisions remained with the main army; they were directly commanded by Lee during this time. Robert Rodes took over D.H. Hill's division. Jackson was mortally wounded during the Battle of Chancellorsville. Afterwards, Lee divided the army into three corps with three divisions each. Longstreet got the divisions of Pickett, McLaws, and Hood; A.P. Hill got the divisions of Harry Heth, William D. Pender, and Richard Anderson; and Richard Ewell (returning to action after almost a year of recovering from the loss of a leg at Second Bull Run) got the divisions of Robert Rodes, Jubal Early, and Edward "Allegheny" Johnson. A Fourth Corps, under Lt. Gen. Richard H. Anderson, was organized on October 19, 1864; on April 8, 1865, it was merged into the Second Corps. The commanders of the first three corps changed frequently in 1864 and 1865.

By the time of the Pennsylvania invasion, Lee had fixed the organizational defects that plagued the army during its early campaigns and the straggling problems of the Maryland Campaign did not repeat themselves.

After taking over command in mid-1862, Lee began preparing to lead the Army of Northern Virginia for the first time. However, his aggressiveness to attack the Union led to the loss of many troops especially at the Battle of Antietam, which ended up being a turning point in the war for the Union. After the costly victories during the Seven Days Battles and at Second Manassas in August 1862, Lee had now lost a total of 30,000 of his approximately 92,000 troops within three months of becoming the Confederate's top general. Lee then planned to take his troops north into Maryland to destroy a critical railroad bridge across the Susquehanna River at Harrisburg in a letter written to President Davis. Lee even questioned his own plan, as he wrote, "I am aware that the movement is attended with much risk, yet I do not consider success impossible..."^[6] In addition, historians question Lee's aggressiveness to move his army to Maryland. "There can be no sort of doubt that Lee underestimated the exhaustion of his army after Second Manassas. That is, in reality, the major criticism of the Maryland operation: he carried worn-out men across the Potomac."^[7] His men were also underarmed and underfed, so the journey to Maryland added to the overall exhaustion. Once Lee arrived in Maryland and was preparing for Antietam, he made another controversial decision. Against the advice from General Longstreet and Jackson, Lee split his troops into four parts to attack the Union from different fronts. Clearly outnumbered and opposed to Lee's plan, Longstreet stated, "General, I wish we could stand still and let the damned Yankees come to us!"^[8] As the fighting played out on September 17, 1862, known as the bloodiest single-day battle in American history, the battles at Dunker Church and Burnside's Bridge proved to be too much for Lee and his Confederate army. Luckily for Lee, the arrival of A.P. Hill's troops and the mixture of McClellan's and Burnside's sluggishness, saved Lee's Army of Northern Virginia and allowed them to barely hold off the Union in Maryland.^[9]

Department of Northern Virginia, October 22, 1861

The Military Department of Northern Virginia was embattled on October 22, 1861.^[11] The department initially consisted of three districts under the overall command of General Joseph E. Johnston.

On February 28, 1862, there were 47,617 soldiers present for duty to the military district.^[12] The Cavalry Brigade was provided from the Potomac's Military District and under direct control from the Defense District. The artillery formed an Artillery Corps with 109 cannons.

Organization April 30, 1862

The Army of Northern Virginia was established on March 14, 1862, again under Johnston. Though the military department stayed existent its role changed into an administrative division for most of the war.

At the outset of the Peninsula Campaign the Army of Northern Virginia had more than 55,633 soldiers. The cannon was assigned to the brigades, as well as the Reserve's artillery. Nominally, Jackson's Corps in the Shenandoah Valley, was subordinate to the Army. Since Jackson led his own campaign at the time of the Peninsula Campaign and was not under Lee's direct command this overview does not include his three divisions.

The Army's organization soon proved inept in the course of the Peninsula Campaign. The corps-like structure was rearranged before the Seven Days Battle to converge with the requirements of actual command. In the course of this battle the Army featured two Corps; Jackson's and Magruder's, with four and three divisions respectively, and three actual divisions with five to six brigades. Also the Defense District of North Carolina answered directly to the Army as well as the Reserve Artillery with six battalions and the cavalry with six regiments.^[13] The army's complete strength was about 90,000 soldiers. The exact strength cannot be determined, because only a few notes for actual provisionings survived. The estimated strength results, if not explicitly noted, from in-battle dispatches.

Organization at the setout of the Northern Virginia Campaign

The Seven Days Battle showed the Army still suffered from insufficient organization in army command. General Lee subdivided the army again, but this time only with single commands. He introduced a corps-like structure of command, and as an intermediate army management he named the left and right wing. The Army was organized on August 28, 1862, as follows.^[14]

The Army's Reserve Artillery consisted of one regiment and two battalions. They stayed in the area of Richmond in the course of the whole Northern Virginia Campaign and only returned on September 3, 1862, to the Army. Major General Hill's Division also remained in the eastern parts of Richmond with the order to bind McClellan's attention as long as possible.^[15] As it became predictable that the Army of the Potomac would soon be transferred to support Pope, Lee ordered the Division north.^[16] Hill never entered battle in the campaign. A total of about 54,000 soldiers saw action throughout the campaign.

Organization at the beginning of the Maryland Campaign

The Army's losses before and following the Battle of Second Manassas needed to be replaced before the Maryland Campaign could commence. While fundamental changes in the Army's command structure were not necessary, General Lee exchanged divisions and brigades or added additional strength to some. The wings of the Army were now officially called 'Corps'. In the Maryland Campaign the Army was subdivided as follows.^[17]

While organization of the corps was found to be generally reliable, the corps' subdivision into four or five divisions hampered overall ease of command. General Lee had already considered before the Battle of Antietam to slim down the overall structure, but intended there be no changes in leadership. The Confederate Congress authorized the establishment of the Corps, and President Davis affirmed the assignment of the commanders and promoted Major Generals Longstreet and Jackson to Lieutenant Generals. General Lee announced this in Special Order 234 on November 6, 1862.^[18] About 60,000 soldiers served at the Maryland Campaign.

Fredericksburg and Chancellorsville

In the days following the Battle of Chancellorsville there were no changes in the army's command structure or hierarchy. The army replaced its own losses with new recruits and soldiers returning to duty. Lee made demands that all regiments had to be consolidated solely with recruits originating from their corresponding home states.

Following the Battle of Fredericksburg the Army of Northern Virginia could muster over 72,497 soldiers^[19] not counting other personnel. Not figuring into this overall number is the fact that Lee had made the decision to station a whole division and a single cavalry brigade at Shenandoah Valley for protection at this time and these troops are missing from the total estimates.

During the autumn of 1862 lasting throughout the following winter the army faced the Army of the Potomac at Rappahannock. Thereout arose a new problem: Because of the necessity to always show its presence to the enemy there were only limited supplies available for the army from the surrounding villages and towns. Any army at these times supplied itself along the way while moving across the theater of war. Even ordering supplies through the use of the rail, if it was an available option at all, took up considerable time and efforts and supply treks by wagons were potentially prone to enemy assaults. This left Lee with few options and therefore he gave the special order on December 24, 1862, to move half of his artillery into the hinterlands to have his horses better supplied. He forbade to assign all of the horses to any other task than official assignments.^[20]

On February 15, 1863, Lee rearranged his artillery. Six battalions were assigned to both corps, and the reserve was composed out of two more battalions.^[21] The Confederate War Department strongly suggested in position papers to Lee dating from the February 18th, 1862 to station two divisions at the Atlantic coast. Lee was not averse to any such demands, probably very much on the contrary, because of the tight position he was in with the general lack of provisions, so he gave orders to General Longstreet to have it done so. Both of the assigned divisions only returned to join the Army of Northern Virginia again following the Battle of Chancellorsville. The army was composed at this battle out of over 61.500 soldiers.^[22]

Organization from May 30, 1863, until April 9, 1865

Lee took Jackson's death as an opportunity to subdivide the North Virginia Corps again. President Jefferson Davis agreed to the subdivision and ordered Lee in his Special Order Nr. 146 to reorganize the Army.^[23]

Lee ordered the artillery battalions of the Reserve Artillery to serve directly with the Corps for the duration of the Gettysburg Campaign. The Army of Northern Virginia now comprised a total of 75,054 soldiers at the Battle of Gettysburg.^[24]

The army fielded more than 241 cannons following the Battle of Gettysburg.^[25]

On September 9, General Lee had to dispatch the First Corps to Braxton Bragg's Army of Tennessee. Following this the army was resubordinated again. Changes were not significant; only the cavalry saw important reorganization.^[26]

The Army's strength was then 55,221 soldiers. The changes in command until December 31, 1863, were only minor. Cooke's Brigade was assigned to serve with Heth's Division, Hampton's Division grew by a cavalry brigade and the Third Corps gained an additional artillery battalion. Imboden's Command remained at Shenandoah Valley and was taken over by Major General Early as the Defense District of Shenandoah Valley. The strength of the army was 54,715 men on December 31.

The organization of the Army of Northern Virginia did not change until the end of the war. The Army featured several corps, the corps featured several divisions, and the artillery was divided between the corps. The strength of the Army grew in the first six months from about 46,380 to 62,230 soldiers. The army was assigned in July to the Defense District of North Carolina and Richmond. In the course of the Richmond-Petersburg Campaign the number of soldiers temporarily grew to 82,633 while parts of the Army were under the command by Lieutenant General Early in Shenandoah Valley.

In 1864, the Army of Northern Virginia fought forces over twice as strong as that of the Potomac, James and Shenandoah Army in Grant's Overland Campaign, Early's Raid against the Baltimore and Ohio Railroad, the Richmond-Petersburg Campaign, and Shenandoah Campaign in the Shenandoah Valley. The Army reorganized on January 31, 1865^[27] because 69,659 soldiers were fit for battle, but 4,500 or more had no rifles.^[28]
