Major battle (1862) of the American Civil War
The Battle of Fredericksburg was fought December 11–15, 1862, in and around Fredericksburg, Virginia, in the Eastern Theater of the American Civil War. The combat between the Union Army of the Potomac commanded by Maj. Gen. Ambrose Burnside and the Confederate Army of Northern Virginia under Gen. Robert E. Lee included futile frontal attacks by the Union army on December 13 against entrenched Confederate defenders along the Sunken Wall on the heights behind the city. It is remembered as one of the most one-sided battles of the war, with Union casualties more than twice as heavy as those suffered by the Confederates. A visitor to the battlefield described the battle as a "butchery" to U.S. President Abraham Lincoln.
Burnside planned to cross the Rappahannock River at Fredericksburg in mid-November and race to the Confederate capital of Richmond before Lee's army could stop him. Burnside needed to receive the necessary pontoon bridges in time, and Lee moved his army to block the crossings. When the Union army was finally able to build its bridges and cross under fire, direct combat within the city resulted on December 11–12. Union troops prepared to assault Confederate defensive positions south of the city and on a strongly fortified ridge just west of the city known as Marye's Heights.
On December 13, the Left Grand Division of Maj. Gen. William B. Franklin was able to pierce the first defensive line of Confederate Lt. Gen. Stonewall Jackson to the south but was finally repulsed. Burnside ordered the Right and Center Grand Divisions of major generals Edwin V. Sumner and Joseph Hooker to launch multiple frontal assaults against Lt. Gen. James Longstreet's position on Marye's Heights – all were repulsed with heavy losses. On December 15, Burnside withdrew his army, ending another failed Union campaign in the Eastern Theater.
Background.
Military situation.
In November 1862, U.S. President Abraham Lincoln needed to demonstrate the success of the Union war effort before the Northern public lost confidence in his administration. Confederate armies had been on the move earlier in the fall, invading Kentucky and Maryland. Although each had been turned back, those armies remained intact and capable of further action. Lincoln urged Major General Ulysses S. Grant to advance against the Confederate stronghold of Vicksburg, Mississippi. He replaced Maj. Gen. Don Carlos Buell with Maj. Gen. William S. Rosecrans, hoping for a more aggressive posture against the Confederates in Tennessee, and on November 5, seeing that his replacement of Buell had not stimulated Maj. Gen. George B. McClellan went into action, and he issued orders to replace McClellan in command of the Army of the Potomac in Virginia. McClellan had stopped General Robert E. Lee's forces at the Battle of Antietam in Maryland but had not been able to destroy Lee's army, nor did he pursue Lee back into Virginia aggressively enough for Lincoln.
McClellan's replacement was Maj. Gen. Ambrose Burnside, the commander of the IX Corps. Burnside had established a reputation as an independent commander, with successful operations earlier that year in coastal North Carolina and, unlike McClellan, had no apparent political ambitions. However, he felt unqualified for army-level command and objected when offered the position. He accepted only when it was made clear to him that McClellan would be replaced in any event and that a choice for command was Maj. Gen. Joseph Hooker, whom Burnside disliked and distrusted. Burnside assumed command on November 7.
Burnside's plan.
In response to prodding from Lincoln and general-in-chief Maj. Gen. Henry W. Halleck, Burnside planned a late fall offensive; he communicated his plan to Halleck on November 9. The plan relied on quick movement and deception. He would concentrate his army in a visible fashion near Warrenton, feigning a movement on Culpeper Court House, Orange Court House or Gordonsville. He would then rapidly shift his army southeast and cross the Rappahannock River to Fredericksburg, hoping that Lee would not move, unclear as to Burnside's intentions. At the same time, the Union Army made a rapid movement against Richmond, south along the Richmond, Fredericksburg and Potomac Railroad (RF&amp;P) from Fredericksburg. Burnside selected this plan because he was concerned that if he were to move directly south from Warrenton, he would be exposed to a flanking attack from Lt. Gen. Thomas J. "Stonewall" Jackson, whose corps was at that time in the Shenandoah Valley south of Winchester. He also believed that the Orange and Alexandria Railroad (O&amp;A) would need to be an adequate supply line. (Burnside was also influenced by plans McClellan began developing just before being relieved. Aware that Lee had blocked the O&amp;A, McClellan considered a route through Fredericksburg and ordered a small group of cavalrymen commanded by Captain Ulric Dahlgren to investigate the condition of the RF&amp;P.) While Burnside began assembling a supply base at Falmouth, near Fredericksburg, the Lincoln administration undertook a lengthy debate about the wisdom of his plan, which differed from the president's preference of a movement south on the O&amp;A and a direct confrontation with Lee's army instead of the movement focused on the city of Richmond. Lincoln reluctantly approved the plan on November 14 but cautioned his general to move with great speed, certainly doubting that Lee would react as Burnside anticipated.
Movement to battle.
The Union Army began marching on November 15, and the first elements arrived in Falmouth on November 17. Burnside's plan quickly went awry—he had ordered pontoon bridges to be sent to the front and assembled for his quick crossing of the Rappahannock, but because of administrative bungling, the bridges did not arrive on time. Burnside first requisitioned the pontoon bridging (along with many other provisions) on November 7 when he detailed his plan to Halleck. The plan was sent to the attention of Brig. Gen. George Washington Cullum, the chief of staff in Washington (received on November 9). Plans called for both riverine and overland movement of the pontoon trains to Falmouth. On November 14, the 50th New York Engineers reported the pontoons were ready to move, except for a lack of the 270 horses needed to move them. Unknown to Burnside, most of the bridging was still on the upper Potomac. Communications between Burnside's staff engineer Cyrus B. Comstock and the Engineer Brigade commander Daniel P. Woodbury indicate that Burnside had assumed the bridging was en route to Washington based on orders given on November 6.
As Maj. Gen. Edwin V. Sumner arrived, he strongly urged an immediate crossing of the river to scatter the token Confederate force of 500 men in the town and occupying the commanding heights to the west. Burnside became anxious, concerned that the increasing autumn rains would make the fording points unusable and that Sumner might be cut off and destroyed, ordering Sumner to wait in Falmouth.
Lee at first anticipated that Burnside would beat him across the Rappahannock and that to protect Richmond, he would assume the next defensible position to the south, the North Anna River. But when he saw how slowly Burnside was moving (and Confederate President Jefferson Davis expressed reservations about planning for a battle so close to Richmond), he directed all of his army toward Fredericksburg. By November 23, the corps commanded by Lt. Gen. James Longstreet had arrived and Lee placed them on the ridge known as Marye's Heights to the west of town, with Anderson's division on the far left, McLaws's directly behind the town, and Pickett's and Hood's to the right. He sent for Jackson on November 26, but his Second Corps commander had anticipated the need and began forced-marching his troops from Winchester on November 22, covering as many as 20 miles a day. Jackson arrived at Lee's headquarters on November 29 and his divisions were deployed to prevent Burnside crossing downstream from Fredericksburg: D.H. Hill's division moved to Port Royal, 18 miles down river; Early's 12 miles down river at Skinker's Neck; A.P. Hill's at Thomas Yerby's house, "Belvoir", about 6 miles southeast of town; and Taliaferro's along the RF&amp;P Railroad, 4 miles south at Guinea Station.
The boats and equipment for a single pontoon bridge arrived at Falmouth on November 25, much too late to enable the Army of the Potomac to cross the river without opposition. Burnside still had an opportunity, however, because by then he was facing only half of Lee's army, not yet dug in, and if he acted quickly, he might have been able to attack Longstreet and defeat him before Jackson arrived. Once again he squandered his opportunity. The full complement of bridges arrived at the end of the month, but by this time Jackson was present and Longstreet was preparing strong defenses.
Burnside originally planned to cross his army east of Fredericksburg at Skinker's Neck, but an advance movement by Federal gunboats to there was fired upon and drew Early's and D.H. Hill's divisions into that area, a movement spotted by Union balloon observers. Now assuming that Lee had anticipated his plan, Burnside guessed that the Confederates had weakened their left and center to concentrate against him on their right. So he decided to cross directly at Fredericksburg. On December 9, he wrote to Halleck, "I think now the enemy will be more surprised by a crossing immediately in our front than any other part of the river. ... I'm convinced that a large force of the enemy is now concentrated at Port Royal, its left resting on Fredericksburg, which we hope to turn." In addition to his numerical advantage in troop strength, Burnside also had the advantage of knowing his army could not be attacked effectively. On the other side of the Rappahannock, 220 artillery pieces had been located on the ridge known as Stafford Heights to prevent Lee's army from mounting any major counterattacks.
Opposing forces.
Union.
Burnside organized his Army of the Potomac into three so-called "grand divisions", organizations that included infantry corps, cavalry, and artillery, comprising 120,000 men, of whom 114,000 would be engaged in the coming battle:
Confederate.
Robert E. Lee's Army of Northern Virginia had nearly 79,000 men, with 72,500 engaged. His organization of the army in corps was approved by an act of the Confederate Congress on November 6, 1862, and consisted of:
The two armies at Fredericksburg represented the largest number of armed men that ever confronted each other for combat during the Civil War.
Battle.
Crossing the Rappahannock, December 11–12.
Union engineers began to assemble six pontoon bridges before dawn on December 11, two just north of the town center, a third on the southern end of town, and three farther south, near the confluence of the Rappahannock and Deep Run. The engineers constructing the bridge directly across from the city came under punishing fire from Confederate sharpshooters, primarily from the Mississippi brigade of Brig. Gen. William Barksdale, in command of the town defenses. Union artillery attempted to dislodge the sharpshooters, but their positions in the cellars of houses rendered the fire from 150 guns mostly ineffective. Eventually Burnside's artillery commander, Brig. Gen. Henry J. Hunt, convinced him to send infantry landing parties over in the pontoon boats to secure a small bridgehead and rout the sharpshooters. Col. Norman J. Hall volunteered his brigade for this assignment. Burnside suddenly turned reluctant, lamenting to Hall in front of his men that "the effort meant death to most of those who should undertake the voyage." When his men responded to Hall's request with three cheers, Burnside relented. At 3:00 p.m., the Union artillery began a preparatory bombardment and 135 infantrymen from the 7th Michigan and the 19th Massachusetts crowded into the small boats, and the 20th Massachusetts followed soon after. They crossed successfully and spread out in a skirmish line to clear the sharpshooters. Although some of the Confederates surrendered, fighting proceeded street by street through the town as the engineers completed the bridges. Sumner's Right Grand Division began crossing at 4:30 p.m., but the bulk of his men did not cross until December 12. Hooker's Center Grand Division crossed on December 13, using both the northern and southern bridges.
The clearing of the city buildings by Sumner's infantry and by artillery fire from across the river began the first major urban combat of both the war and American history. Union gunners sent more than 5,000 shells against the town and the ridges to the west. By nightfall, four brigades of Union troops occupied the town, which they looted with a fury that had not been seen
