On September 14, 1862, during the fierce, close-quarters combat of the Battle of South Mountain in Maryland, an extraordinary kinship of destiny was forged between two future American presidents serving in the 23rd Ohio Volunteer Infantry. Lieutenant Colonel Rutherford B. Hayes, a cultured gentleman of high purpose who commanded the regiment, had spent months observing and drawing close to his young, dedicated commissary sergeant, nineteen-year-old William McKinley, forming an invisible bond of brotherhood that transcended their vast difference in military rank.
The regiment faced a devastating baptism of fire as they charged up the rugged slopes of Fox’s Gap to prevent General Robert E. Lee’s army from invading the North. Hayes was among the first to be severely wounded, his arm shattered by a musket ball, yet he stubbornly continued to direct his men and shout commands while bleeding heavily on the field. Inspired by their leader’s quiet grit and sustained by McKinley’s tireless logistical efforts to rush food and ammunition directly to the firing line, the regiment executed three daring bayonet charges, losing over two hundred men while their battle flags were completely riddled with bullets.
The intense shared crucible of South Mountain permanently bound the lives of Hayes and McKinley, creating a lifelong personal and political alliance rooted in the shared trauma of the Civil War. Their mutual devotion illustrated how the extreme trials of the battlefield could erase institutional boundaries, turning a combat commander and a teenage sergeant into lifelong partners whose shared aims eventually carried both men from the blood-stained soil of Maryland to the highest office in the nation.
