Chancellorsville

Fought from April 30 to May 6, 1863, Chancellorsville stands as one of the major clashes of the American Civil War, spanning 1861 to 1865, and it formed the central engagement of the broader campaign bearing its name. Confederate commander Robert E. Lee gambled by splitting his forces while facing a much larger opposing army, a choice that yielded one of the war's most striking Confederate triumphs, one that some historians have called Lee's "perfect battle." That success, born from Lee's boldness paired with the hesitant leadership of Union general Joseph Hooker, came at a steep cost. Among the casualties was Lt. Gen. Thomas J. "Stonewall" Jackson, struck down by his own men's gunfire. Surgeons amputated his left arm, but pneumonia claimed his life eight days afterward, a blow Lee compared to losing his right arm.

The two opposing armies had spent the winter of 1862 to 1863 encamped near Fredericksburg, watching each other across the landscape. The campaign got underway when Hooker quietly marched most of his troops upriver along the Rappahannock's left bank before crossing on the morning of April 27. Around this same period, Union horsemen led by Maj. Gen. George Stoneman set out on an extended raid aimed at disrupting Lee's supply routes. After fording the Rapidan at Germanna and Ely's, Federal foot soldiers gathered near Chancellorsville by April 30. Hooker envisioned striking Lee from two directions at once, joining this force with the troops stationed opposite Fredericksburg for a pincer movement.

By May 1, Hooker pushed forward from Chancellorsville, but Lee, though outnumbered, chose to divide his troops, leaving only a modest contingent at Fredericksburg to hold off Maj. Gen. John Sedgwick while directing roughly four-fifths of his men against Hooker's advancing column. Ignoring the protests of his own officers, Hooker pulled his forces back into defensive positions around Chancellorsville, surrendering control of the fight to his opponent. The next day, May 2, Lee split his army once more, dispatching Jackson's full corps on a wide flanking route that shattered the Union XI Corps. Scouting ahead of his own lines after dusk, Jackson fell wounded from gunfire fired by his own troops. Cavalry officer Maj. Gen. J. E. B. Stuart stepped in temporarily to lead the corps in his place.

The heaviest combat of the entire battle, and what became the second deadliest single day of the whole war, unfolded on May 3, as Lee hurled repeated assaults at the Union lines near Chancellorsville. Both sides suffered heavily, and Hooker's main force was compelled to retreat further. On that same day, Sedgwick pushed his men across the Rappahannock, overwhelmed the thin Confederate defense at Marye's Heights during what became known as the Second Battle of Fredericksburg, and then pressed westward. Confederate troops managed to slow this advance through a successful holding action at Salem Church. The following day, Lee shifted his attention away from Hooker to confront Sedgwick directly, pushing him back toward Banks' Ford and nearly encircling his position from three sides. Sedgwick pulled his men back across the ford in the early hours of May 5. Lee then redirected his focus toward Hooker, who ferried the remainder of his army over U.S. Ford under cover of darkness that same night.

The campaign concluded on May 7, when Stoneman's cavalry finally linked up with Union positions east of Richmond. Both armies settled back into their former posts on opposite sides of the Rappahannock near Fredericksburg. Despite mourning Jackson's death, Lee restructured his command and, buoyed by his victory, began laying the groundwork for what would evolve into the Gettysburg campaign just a month afterward.

Background

During the war's Eastern Theater, Union strategy centered on capturing Richmond, the Confederate seat of government in Virginia. Four earlier drives on that goal had come to grief. The first collapsed near Washington itself, at First Bull Run in July 1861. Then George B. McClellan tried an amphibious route, putting the Army of the Potomac ashore on the Virginia Peninsula in spring 1862; his troops got within six miles of Richmond before Lee's counterstrokes in the Seven Days drove them back. That summer brought a third setback when John Pope's Army of Virginia went down to defeat at Second Bull Run, and finally, in December 1862, Ambrose Burnside tried pushing through Fredericksburg only to be repulsed there as well.

By January 1863, following that Fredericksburg disaster and the disheartening Mud March, the Army of the Potomac was hemorrhoiding deserters and sinking in morale. Burnside responded by trying to sweep out officers he blamed for the defeat, not realizing Congress alone held the authority to remove them. His purge collapsed, and he tendered his resignation as army commander to Lincoln, even offering to leave the Army altogether. Lincoln talked him into staying in uniform but shifted him west to head the Department of the Ohio instead. Burnside's old IX Corps went to the Virginia Peninsula, a move that led the Confederates to peel off troops from Lee's army under James Longstreet, with consequences for the campaign ahead.

Lincoln had come to believe that destroying Lee's army mattered more than seizing any city, yet he and his commanders understood that menacing Richmond remained the surest bait for forcing Lee into a decisive fight. On January 25, 1863, he turned to a fifth general, Joseph Hooker, known for his combativeness and solid record in lesser commands.

Burnside's exit triggered others. William B. Franklin, a McClellan loyalist who both outranked and personally disliked Hooker, refused to serve beneath him and departed. Edwin V. Sumner, 65 and in failing health, stepped aside as well; reassigned to Missouri, he died before taking up the post. Daniel Butterfield left command of V Corps to become Hooker's chief of staff.

Hooker then overhauled the army, scrapping Burnside's cumbersome grand division structure, partly because too few senior officers remained whom he trusted with multi-corps commands. He consolidated the cavalry into its own corps under George Stoneman, previously in charge of III Corps at Fredericksburg, but took the opposite approach with artillery, scattering its battalions among division commanders and stripping coordinating authority from chief of artillery Henry J. Hunt.

As an administrator Hooker proved highly capable, lifting morale that had cratered under his predecessor. He overhauled soldiers' rations, cleaned up camp sanitation, tightened quartermaster accountability, introduced supervised company cooks, reformed hospitals, revised furlough policy, cracked down on desertion, and sharpened both drill and officer training.

He also benefited from intelligence far better than what earlier commanders had possessed. Butterfield tasked Col. George H. Sharpe of the 120th New York Infantry with building a new Bureau of Military Information, operating under provost marshal Marsena R. Patrick. Earlier efforts, run by figures like Allan Pinkerton, had relied solely on questioning prisoners, deserters, escaped slaves, and refugees. The new bureau widened its net to include cavalry and infantry scouting, spies, signal stations, and observation balloons. Armed with this richer picture, Hooker concluded that crossing the Rappahannock without being slaughtered in a frontal assault, as had happened at Antietam and Fredericksburg, would require what he called stratagem rather than brute force.

The two armies sat opposite each other along the Rappahannock, Hooker's men wintering at Falmouth near Fredericksburg. His plan surpassed earlier ones in sophistication. Stoneman would take 10,000 troopers upstream, cross the river, and strike deep into Confederate territory, wrecking the rail supply line linking Richmond to Fredericksburg and severing Lee's communications. Hooker expected this threat would push Lee to abandon his defenses and retreat toward the capital, at which point Union infantry would cross in pursuit and catch him exposed. Stoneman tried this on April 13, but swollen rivers made the Sulphur Spring cr

Battle

Before sunrise on May 1, Jackson's troops set out marching westward to unite with Anderson. At 8 a.m. Jackson met Anderson himself close to Zoan Church and discovered that McLaws's division had already reached the defensive line. Yet Jackson had no interest in staying put. At 11 a.m. he ordered his forces forward along two separate roads heading toward Chancellorsville: McLaws's division together with Brig. Gen. William Mahone's brigade took the Turnpike, while Anderson's remaining brigades and Jackson's newly arrived units moved along the Plank Road.

Almost simultaneously, Hooker directed his own troops to push eastward on three routes. Two divisions of Meade's V Corps, those of Griffin and Humphreys, moved along the River Road toward Banks's Ford, while Sykes's division took the Turnpike. Slocum's XII Corps advanced on the Plank Road, backed closely by Howard's XI Corps. Couch's II Corps stayed in reserve, soon to be joined there by Sickles's III Corps.

The opening shots of the battle rang out at 11:20 a.m. when the two forces met. McLaws's opening assault drove Sykes's division backward, though the Union commander rallied his men and reclaimed the ground. Anderson then dispatched Brig. Gen. Ambrose Wright's brigade along an unfinished rail bed south of the Plank Road to swing around Slocum's right side. Such a maneuver could have spelled trouble, but Howard's approaching XI Corps was positioned to handle Wright.

Because Sykes had pushed further ahead than Slocum on his flank, he found himself exposed and was compelled to pull back in good order by 2 p.m., settling behind Hancock's division of the II Corps, which Hooker had ordered up to help stop the Confederate push. Meanwhile Meade's other two divisions made solid headway along the River Road, drawing near their target at Banks's Ford.

Even with circumstances tilting in his favor, Hooker called off his brief push forward. This decision might reveal uncertainty in managing the complicated maneuvers of such a massive force for the first time, given that he had previously excelled as an aggressive division and corps commander. Still, before the campaign even started, he had resolved to fight defensively and compel Lee's smaller army to attack his larger one. At Fredericksburg on December 13, 1862, Union forces had taken the offensive and suffered a costly defeat.

Hooker understood that Lee's army could not absorb such losses and remain viable, so he instructed his men to fall back into the Wilderness and establish defenses around Chancellorsville, hoping to provoke Lee into either attacking or retreating with a larger force at his back. Adding confusion, he then issued a follow-up order telling his commanders to hold their ground until 5 p.m., but most units had already begun retreating by the time this message arrived. That night Hooker told his corps commanders in a message that he trusted the day's pause in fighting would embolden the enemy to attack.

His subordinate officers reacted with shock and anger at this reversal. They recognized that the ground near Zoan Church sat on relatively elevated terrain, giving infantry and artillery room to maneuver beyond the tangled Wilderness. Meade famously remarked that if they could not hold the hilltop, they certainly could not hold its base. Looking back, several participants and numerous later historians concluded that Hooker essentially threw away the campaign that day. Still, historian Stephen W. Sears noted that more than mere timidity shaped Hooker's thinking.

The contested terrain amounted to little beyond a clearing surrounded by the Wilderness, reachable only by two narrow roads. Confederate forces had rapidly massed Jackson's aggressive corps against the advancing Union columns, giving them roughly a 48,000 to 30,000 numerical edge in that sector and making it hard for Federal troops to form effective lines. Meade's two divisions on the River Road sat too far away to

Stephen Crane drew on this engagement as the foundation for his 1895 novel The Red Badge of Courage. F. Scott Fitzgerald also used it as a setting, crafting a short story called "The Night at Chancellorsville," which appeared in Esquire Magazine's February 1935 issue. Additionally, the clash appeared on screen in 2003 through the film Gods and Generals, itself adapted from a novel bearing the same title. Both the book and the movie concentrate their attention on Jackson's attack against the Union right flank, along with the wound he suffered there and his eventual death.
