From October 16th to 18th, 1859, American abolitionist John Brown attempted to initiate a slave revolt in Southern states by raiding an armory in Harpers Ferry, Virginia (now West Virginia). The raid is frequently cited as one of the primary causes of the American Civil War.
Brown's party of 22 was defeated by a platoon of U.S. Marines, led by First Lieutenant Israel Greene. Ten of the raiders were killed during the raid, seven were tried and executed afterwards, and five escaped. Several of those present at the raid would later be prominent figures in the Civil War: Colonel Robert E. Lee was in overall command of the operation to retake the arsenal. Stonewall Jackson and Jeb Stuart were among the troops guarding the arrested Brown, and John Wilkes Booth was a spectator at Brown's execution. John Brown had originally asked Harriet Tubman and Frederick Douglass, both of whom he had met in his transformative years as an abolitionist in Springfield, Massachusetts, to join him in his raid, but Tubman was prevented by illness and Douglass declined, as he believed Brown's plan was suicidal.
