Armory town where John Brown struck at slavery
Harpers Ferry, West Virginia, where the Potomac and Shenandoah Rivers meet

Harpers Ferry, at the meeting of the Potomac and Shenandoah Rivers, was home to a U.S. armory where interchangeable parts were first successfully used in manufacturing. In October 1859 the abolitionist John Brown seized the armory in a failed attempt to spark a slave uprising. During the Civil War it saw the largest surrender of Union troops of the war. After the war it became home to one of the earliest integrated schools in the country.

During the Civil War, Harpers Ferry was the site of the largest surrender of Federal troops during the war. After the war, freedpeople were educated in one of the earliest integrated schools in the country.
