On a gray December morning in 1862, the largest mass execution in American history unfolded on a scaffold in Mankato, Minnesota, as 38 Dakota men were hanged simultaneously before a crowd of 4,000 spectators. The event was the bloody culmination of a six-week uprising that claimed the lives of over 500 American settlers and soldiers, and it left a scar on the nation’s conscience that remains raw more than 160 years later. The gallows, built in the shape of a hollow square, held the condemned men on four sides, their fates sealed by a single rope cut by a civilian whose own family had been slaughtered in the conflict.

The roots of this cataclysm lie not in a sudden burst of savagery, but in a slow, grinding betrayal of treaty obligations by the United States government. In the years leading up to the conflict, the Dakota people had been systematically pushed from their ancestral lands as waves of white settlers poured into Minnesota Territory, their numbers swelling from a trickle to over 170,000 in a single decade. The 7,000 remaining Dakota were confined to reservations, promised annuities and food rations in exchange for their land, but the payments were delayed, and the food never arrived.

By the summer of 1862, the situation had become desperate. A failed crop and a brutal winter had left the Dakota starving, their traditional hunting grounds depleted by the encroachment of settlers. When tribal leaders appealed to local traders for food on credit, they were met with cruel indifference.

Andrew Myrick, a trader at the Redwood Agency, famously declared that if the Indians were hungry, they should “eat grass and their own dung.” The insult was a spark that would ignite a powder keg of rage and desperation.

On August 17, 1862, four young Dakota men, returning from a hunting trip, encountered a settler’s farm. Accounts differ on what happened next, but violence erupted, and five settlers, including two women, were killed. The warriors knew that reprisals would be swift and brutal, and they brought their actions before a tribal council.

Little Crow, a chief who had long advocated for peaceful coexistence with the Americans, initially resisted calls for war, but he ultimately agreed to lead the uprising, knowing that his people faced annihilation either way.

The following morning, Little Crow led an attack on the Redwood Agency, where dozens of warriors surrounded the trading posts. Thirteen settlers were killed in the initial assault, but the chaos of looting allowed many others to escape. Andrew Myrick, the trader who had mocked the starving Dakota, was not among the survivors.

His body was found beheaded, his mouth stuffed with grass, a grim and symbolic message to those who had dismissed the tribe’s suffering.

The uprising quickly spread across the Minnesota River Valley, as war parties raided homesteads, towns, and military outposts. Settlers fled in terror, seeking refuge at Fort Ridgely and other fortified positions. The Dakota, emboldened by their initial success, continued their campaign of violence, killing men, taking women and children captive, and burning homes to the ground.

The stories of survivors, many of them young women and girls, paint a harrowing picture of fear, abuse, and loss.

One such survivor was Mary Schwandt, a 13-year-old girl who had just begun working for a family near the agencies when the uprising began. She was captured by Dakota warriors, who shot the men she was traveling with and took her prisoner. For six weeks, she was held captive, subjected to threats and degradation, and forced to witness the death of a friend.

She learned of her own family’s murder when she recognized their belongings in the hands of her captors. Only her brother survived, left for dead with a tomahawk wound to the head.

Mary was ultimately saved by an older Dakota woman who bought her for a pony and protected her from further harm. Her story, like those of dozens of other captives, reveals the complexity of the conflict, where acts of cruelty were often balanced by acts of mercy. Some Dakota warriors went out of their way to protect settlers they knew, and even Little Crow spared the lives of some of his acquaintances at the Redwood Agency.

But the overwhelming tide of violence was one of death and destruction.

The uprising was never a military match for the United States. Colonel Henry Sibley, commanding a force of militia and regular troops, moved to suppress the rebellion, and after a decisive victory at the Battle of Wood Lake in late September, the Dakota were effectively defeated. Little Crow fled, and Sibley, lacking the manpower to pursue him, instead focused on freeing the 269 captives held by the Dakota.

Among them was Mary Schwandt, who was reunited with the remnants of her shattered world.

The human cost of the uprising was staggering. More than 358 American civilians were killed, along with over 100 militiamen and soldiers. The Dakota lost an estimated 150 warriors, but their suffering was far from over.

Over 2,000 Dakota were taken into custody, many of them having surrendered in the hope of leniency. Instead, they were herded into internment camps, where hundreds died of disease and exposure over the following months.

Colonel Sibley ordered the creation of a military commission to try the captured Dakota, but the proceedings were a travesty of justice. Trials lasted only minutes, with no defense allowed and survivors of the massacres pointing fingers at accused warriors. In just over a week, over 300 Dakota were found guilty of murder and other atrocities and sentenced to death.

The verdicts were sent to President Abraham Lincoln for review, and he, along with two lawyers, spent weeks examining the cases.

Lincoln, mindful of the political and moral implications, chose to commute the sentences of all but 38 of the condemned men. He ordered that only those who had participated in the massacre of settlers or the violation of women should be executed. The decision infuriated Minnesota Governor Alexander Ramsey, who warned Lincoln that the settlers would take private revenge if the full sentence was not carried out.

Lincoln stood firm, but the stage was set for the grim spectacle that would unfold on December 26, 1862.

The gallows in Mankato were constructed in a square, with the 38 condemned men standing on a central platform that would drop when a single rope was cut. Citizens of the area were offered money for the privilege of cutting the rope, and the honor went to William Duley, a man whose family had been killed in the massacres. As the Dakota sang their death song, a drum pounded, and at 10:15 a.

m. , the scaffold fell. The crowd of 4,000 watched in silence as the men were hanged, the largest single-day execution in American history.

The aftermath of the execution was as brutal as the event itself. The remaining Dakota prisoners were held in squalid camps, and hundreds died of disease. The United States government declared all previous treaties with the Dakota null and void, and the tribe was expelled from Minnesota entirely.

A bounty of $25 was offered for the scalp of any male Indian who remained behind, a chilling incentive for vigilante violence. Little Crow, who had escaped the initial fighting, was shot and killed in 1863 while picking raspberries with his son, and his scalp was put on display at the Minnesota Historical Society.

Mary Schwandt, who survived her ordeal and went on to tell her story, later visited the Historical Society and saw Little Crow’s scalp among the relics. She wrote that she felt a sense of satisfaction at the sight, a sentiment that speaks to the deep and enduring trauma of the settlers who lived through the uprising. For them, the Dakota were savage murderers, and the execution of the 38 men was a just and necessary act of retribution.

For the Dakota, the hanging was the final, brutal chapter in a story of broken promises and genocide.

The dark truth of the largest execution in American history is that both sides believed they were right. The settlers saw themselves as pioneers building a better life, and they viewed the Dakota as obstacles to be removed. The Dakota saw themselves as a people fighting for survival, pushed to the brink by a government that had betrayed every promise it made.

The violence that erupted in the summer of 1862 was not the result of innate savagery, but of a system that left no room for peaceful resolution. When the Dakota were told to eat grass and their own dung, they had no choice but to fight back, and the consequences were catastrophic for everyone involved.

The legacy of the Mankato hangings is a complex and painful one. The monument to the execution was removed in 2005, and in recent years, there has been a growing recognition of the injustices suffered by the Dakota people. But the memory of that December morning, when 38 men died on a single scaffold, remains a stark reminder of the cost of manifest destiny and the fragility of justice in times of war.

The story of the Dakota uprising is not a simple tale of good versus evil, but a tragic and deeply human story of desperation, fear, and the devastating consequences of broken promises.
