Stonewall Jackson, American general (d. 1863)

Thomas Jonathan "Stonewall" Jackson, born on January 21, 1824, and passing on May 10, 1863, stands as one of the most iconic and revered military figures of the American Civil War. Serving as a prominent Confederate general from 1861 until his untimely death, Jackson quickly became second only to General Robert E. Lee in public recognition and strategic importance within the Confederacy. His unwavering determination and brilliant tactical acumen played a pivotal role in nearly all major military engagements within the Eastern Theater of the war, often turning the tide of significant battles in favor of the Confederate forces. His death marked a profound loss for the Confederacy, impacting both its military trajectory and the morale of its soldiers and citizens.

Early Life and Military Foundations

Born in what was then part of Virginia, a region that would later become West Virginia, Thomas Jonathan Jackson's path to military distinction began with an appointment to the prestigious United States Military Academy at West Point. Despite facing initial academic challenges, he persevered through sheer diligence and graduated in the class of 1846, a testament to his strong will. Following his graduation, Jackson immediately entered service with the U.S. Army during the Mexican–American War of 1846–1848. It was during this conflict that he first distinguished himself, notably at the Battle of Chapultepec, where his bravery and competence earned him brevet promotions for meritorious conduct.

After his active military service, Jackson embarked on an academic career, teaching at the Virginia Military Institute (VMI) from 1851 to 1861. During his tenure at VMI, he gained a reputation for being a rigid, eccentric, and highly disciplined instructor, which often made him unpopular among his students. His personal life during this period also saw significant events: he married twice. His first wife tragically died in childbirth, but his second wife, Mary Anna Morrison, lived a long life, passing away in 1915.

From VMI Professor to "Stonewall" Jackson

The outbreak of the American Civil War irrevocably altered Jackson's life and career. When Virginia seceded from the Union in May 1861, following the bombardment of Fort Sumter, Jackson unhesitatingly joined the Confederate Army. His military brilliance became evident almost immediately. At the First Battle of Bull Run (also known as the First Battle of Manassas) in July 1861, Jackson commanded a brigade that proved crucial in the Confederate victory. As other Confederate units faltered under intense Union assaults, Jackson's brigade held its ground with remarkable tenacity. It was in this moment that Brigadier General Barnard Elliott Bee Jr., attempting to rally his own retreating troops, famously exclaimed, "Look, there is Jackson standing like a stone wall! Rally behind the Virginians!" This powerful comparison bestowed upon him the enduring nickname "Stonewall," a moniker that perfectly encapsulated his unwavering resolve and battlefield steadfastness.

Strategic Mastermind: The 1862 Campaigns

The year 1862 cemented Jackson's reputation as a tactical genius, particularly through his extraordinary Shenandoah Valley Campaign. Despite suffering an initial setback largely due to faulty intelligence, Jackson launched a series of swift and brilliant maneuvers. In what military historians consider a masterclass in maneuver warfare, he successfully defeated three separate Union armies commanded by Generals John C. Frémont, Nathaniel P. Banks, and James Shields, preventing any of them from reinforcing General George B. McClellan's massive Army of the Potomac, which was then advancing on the Confederate capital of Richmond. This strategic diversion was crucial, forcing the Union high command to divert significant resources away from McClellan's Peninsular Campaign.

Following his stunning success in the Valley, Jackson rapidly moved his three divisions — famously dubbed "Jackson's Foot Cavalry" due to their incredible marching speed — to reinforce General Robert E. Lee's Army of Northern Virginia for the defense of Richmond. However, Jackson's performance during the subsequent Seven Days Battles against McClellan's Army of the Potomac was uncharacteristically subpar, marked by frequent delays in arriving on the battlefield, possibly due to extreme fatigue or illness. Despite this, his presence was still a significant asset.

During the Northern Virginia Campaign that summer, Jackson's forces executed a daring flank march, capturing and destroying a vital Union supply depot at Manassas Junction belonging to General John Pope's Army of Virginia. Subsequently, at the Second Battle of Bull Run (Second Manassas), Jackson's troops heroically withstood repeated and ferocious assaults from Pope's army, forming the anchor of the Confederate defense.

Jackson's command continued to play a pivotal role in September's Maryland Campaign. His forces swiftly captured the strategically important Union arsenal at Harpers Ferry, taking a significant number of prisoners and vast quantities of supplies, before rapidly rejoining Lee. At the climactic Battle of Antietam (Sharpsburg), Jackson's corps provided a crucial defense of the Confederate Army's left flank, repelling numerous Union attacks. Later in December, at the Battle of Fredericksburg, Jackson's corps, despite briefly buckling under immense pressure, ultimately held its ground and helped beat back a major assault by the Union Army under Major General Ambrose Burnside, contributing significantly to one of the most lopsided Confederate victories of the war.

Chancellorsville: A Daring Flank Attack and Tragic End

Jackson's final, and arguably most famous, military contribution occurred in late April and early May 1863 at the Battle of Chancellorsville. Faced with a Union army under Major General Joseph Hooker that significantly outnumbered the Confederates, General Lee made the audacious decision to divide his forces. On May 2, 1863, Jackson executed what military historians often cite as a near-perfect tactical masterpiece: he led his approximately 30,000 troops on a daring 12-mile flank march around Hooker's unsuspecting army, launching a surprise attack against the Union right flank in the late afternoon. This devastating assault caught the Union Eleventh Corps completely by surprise, driving the opposing troops back in disarray for about two miles and shattering their line.

However, this moment of triumph quickly turned to tragedy. That evening, while returning from a dangerous reconnaissance mission to assess the possibility of a night attack, Jackson and his staff were mistakenly fired upon by Confederate pickets, who mistook them for Union cavalry. Jackson was severely wounded in the left arm and hand. His left arm required immediate amputation. Weakened by his wounds and the subsequent surgery, he contracted pneumonia, a common and often fatal complication in the rudimentary medical conditions of the era. Eight days after being shot, on May 10, 1863, Thomas "Stonewall" Jackson succumbed to his illness, depriving the Confederacy of one of its most dynamic and effective commanders.

Enduring Legacy and the "Lost Cause"

Even today, military historians widely regard Thomas "Stonewall" Jackson as one of the most gifted and innovative tactical commanders in American history. His pioneering use of rapid marches, strategic deception, and concentrated force to overwhelm superior numbers remains a subject of study in military academies worldwide. His death proved to be an irreplaceable loss and a severe setback for the Confederacy. It not only diminished its military prospects on the battlefield but also profoundly impacted the morale of its army and the general public, who had come to view him as an almost invincible figure.

Following his death, Jackson's remarkable military exploits and his personal piety developed a legendary quality, contributing significantly to the romanticized narrative of the "Lost Cause of the Confederacy." This ideology, emerging in the post-war era, sought to rationalize the Confederate defeat and preserve the honor of the Southern cause, often portraying figures like Jackson as heroic martyrs embodying chivalry and military genius. "Stonewall" Jackson's name remains synonymous with steadfast courage, strategic brilliance, and an unwavering commitment to his cause.
