On the night of 16 October 1859 John Brown led 21 men, five of them Black, to seize the federal armory at Harpers Ferry, Virginia (today West Virginia). He meant to arm enslaved people for a rising, but none came, and surrounded by militia the raiders were trapped in the armory’s fire-engine house.
On 18 October Marines under Lieutenant Colonel Robert E. Lee broke down the doors and captured Brown. Ten raiders were killed; Brown was tried for treason and hanged at Charles Town on 2 December. The South feared that the North was inciting slave revolt, while some Northerners hailed him as a martyr, and the rift between the sections widened.
