In short: A West Point graduate and decorated veteran of the Mexican–American War, Jesse Lee Reno was a commander who preferred the front lines to the rear. His habit of fighting alongside his troops without visible rank led to a tragic end when a Union soldier mistook him for the enemy.

Jesse Lee Reno was a career United States Army officer whose life spanned the transition from the Mexican–American War to the American Civil War. Born in 1823 in what is now West Virginia, Reno was a graduate of the West Point Class of 1846. His military career was marked by close ties to many of the era's most famous figures, including his classmate and future Confederate leader Thomas J. "Stonewall" Jackson. He was the third child in a large family of eight, born to Lewis Thomas and Rebecca Reno. His family's ancestors had originally arrived in the United States from France in 1770.

During the Mexican–American War in 1847, Reno earned brevets for bravery at the battles of Cerro Gordo and Mexico City. Following the war, he served in various capacities, including as an instructor at West Point and an ordnance officer. In 1861, as the Civil War began, he was appointed brigadier general of volunteers, eventually rising to command the IX Corps of the Army of the Potomac. His earlier service included a two-year expedition to the Utah Territory alongside Brigadier General Albert Sydney Johnston. He also commanded the Mount Vernon Arsenal in Alabama before the state's secession.

Reno was known as a "soldier's soldier" who often fought alongside his men without visible signs of rank. This lack of distinction proved fatal on September 14, 1862, during the Battle of South Mountain. During a scouting mission near Fox's Gap, a member of the 35th Massachusetts wounded Reno in the chest, having confused him with Confederate cavalry. His death was documented by officers such as Ezra A. Carman, and even noted sarcastically by Confederate General Daniel Harvey Hill. Even in his final moments, Reno maintained a startlingly calm demeanor, telling a fellow officer that he was dead. His legacy survives through numerous American landmarks, including Reno, Nevada, and several frontier outposts.
