Early on Sunday, October 16, 1859, the ardent abolitionist John Brown assembled his small army of 18 recruits for prayers and to deliver marching orders. That evening, Brown launched his grandiose plan to capture the federal arsenal at Harpers Ferry and subsequently incite a slave insurrection in Virginia. Brown had a long history of fighting to end slavery in America, but it was a violent history, that was fueled by the Kansas-Nebraska Act and events that took place in Kansas in 1856. Those events included the Pottawatomi Massacre, where Brown and his followers raided the homes of three families — believed to be supporters of slavery — and brutally killed the unarmed men and boys.
Brown Makes Plans to Capture the Federal Arsenal at Harpers Ferry
Afterward, Brown devised a plan to capture the federal arsenal at Harpers Ferry, Virginia, and then lead an armed slave insurrection in Virginia. He spent time in 1857 and 1858 meeting with influential abolitionists, including Frederick Douglas, looking for money to fund his plan. In January 1858, he found the support he needed from Reverend Thomas Wentworth Higginson, Samuel Gridley Howe, Theodore Parker, Franklin Sanborn, and George Stearns. Those five men, plus Gerrit Smith, made up Brown’s primary financial backers, known as the “Secret Six.”

Firefight at Harpers Ferry
By October 16, 1859, Brown was ready to bring years of planning to fruition. Leaving behind three men (including his son Owen) to guard supplies and ammunition, Brown began his short trek toward Harpers Ferry with his remaining 18 recruits at 8 pm. Meeting little resistance, they easily occupied the U. S. Armory and Arsenal and the U. S. Rifle Works on Hall’s Island by 10:30.
