John Brown's raid on Harper's Ferry (also known as John Brown's raid or The raid on Harper's Ferry) was an effort by armed abolitionist John Brown to initiate an armed slave revolt in 1859 by taking over a United States arsenal at Harpers Ferry, Virginia.
 Brown's party of 22 was defeated by a company of U.S. Marines, led by First Lieutenant Israel Greene.
 Colonel Robert E. Lee was in overall command of the operation to retake the arsenal.
 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 would fail.
