Ambrose Burnside, a figure often remembered for his distinctive facial hair, also holds a significant, albeit tragic, place in American Civil War history, particularly concerning the Battle of Fredericksburg. His command of the Army of the Potomac leading up to and during this December 1862 engagement was marked by a profound reluctance to accept the role, a series of operational missteps, and ultimately, a devastating Union defeat. This period highlights
Burnside's personal struggles with high command and the immense pressures placed upon Union generals by President Abraham Lincoln to achieve decisive victories.
Reluctant Ascent to Command
Burnside's path to leading the Army of the Potomac was not one he eagerly sought. Following Major General George B. McClellan's failure to aggressively pursue General Robert E. Lee after the Battle of Antietam, President Lincoln ordered McClellan's removal on November 5, 1862. Burnside was selected as his replacement on November 7. This was not the first time Burnside had been offered such a high command, and he had previously expressed his feelings of being unqualified for army-level leadership. He reluctantly accepted the position, in part because he was informed that if he refused, the command would likely go to Major General Joseph Hooker, whom Burnside disliked and distrusted.His assumption of command took place in a change of command ceremony at the farm of Julia Claggett in New Baltimore, Virginia, on November 9, 1862. McClellan visited the troops to bid them farewell. This reluctant acceptance set a tone for his tenure, as he was a modest and unassuming individual, mindful of his own limitations, who had been propelled into a role he felt ill-suited for. The pressure from President Lincoln for aggressive action was immediate and intense, pushing Burnside towards a plan that would soon prove catastrophic.
The Fredericksburg Plan and Its Fatal Delays
Under pressure from Lincoln, Burnside quickly developed a plan to capture the Confederate capital at Richmond, Virginia, which Lincoln approved on November 14. This plan involved a rapid advance on Fredericksburg, intending to cross the Rappahannock River and move swiftly towards Richmond before Lee could fully react. However, the execution of this plan was plagued by critical delays and misjudgments that ultimately doomed the Union effort.The primary issue was the slow arrival of pontoon bridges, essential for crossing the Rappahannock River. Burnside's advance was rapid, but the attack was stalled because engineers were slow to marshal these bridges. This delay, combined with Burnside's own reluctance to deploy portions of his army across available fording points, gave General Lee ample time to concentrate his forces along Marye's Heights, just west of Fredericksburg. This allowed the Confederates to establish strong defensive positions, effectively negating the Union's initial advantage of surprise and speed.
The Disastrous Assaults and Their Aftermath
With Lee's forces entrenched, the Battle of Fredericksburg on December 13 became a series of futile and costly Union frontal assaults. The main avenue of attack, south of town, was mismanaged, and initial Union breakthroughs went unsupported. The repeated, direct attacks against the heavily fortified Marye's Heights were repulsed with enormous casualties, leading to a humiliating defeat for the Union army. Burnside was deeply upset by the failure of his plan and the immense loss of life. In his distress, he declared he would personally lead an assault by the IX Corps, but his corps commanders ultimately talked him out of this desperate act.Relations between Burnside and his subordinates became severely strained in the wake of the battle. Accepting full blame for the disaster, he offered to retire from the U.S. Army, but this offer was initially refused. His critics, however, were quick to label him the "Butcher of Fredericksburg." In January 1863, Burnside attempted a second offensive against Lee, known derisively as the Mud March, which bogged down in winter rains before achieving anything. Following this, he requested that several openly insubordinate officers be relieved of duty and court-martialed, and again offered his resignation. This time, Lincoln quickly accepted, replacing Burnside with Major General Joseph Hooker on January 26, one of the very officers who had conspired against him.
