In 1857 James Ethan Allen Gibbs, a native of Rockbridge County, secured a patent to make a "twisted loop rotary hook sewing machine," an invention which he had created as a result of watching his mother sew by hand. He was unaware at the time of Elias Howe's sewing machine invention of 1846. After a few years, James A. Willcox added some improvements to Gibbs' sewing machine, and their combined efforts resulted in the Willcox and Gibbs Sewing Machine. On October 16, 1859, John Brown, a freesoiler and an ardent white abolitionist of Kansas and Ohio, led his five sons, eight northern white men and a group of five Negroes on a raid of the federal arsenal at Harper's Ferry, Virginia (now located in West Virginia). Rifles were made and stored here. John Brown had decided to show these slaves how to revolt against their masters. Therefore, he equipped them with arms, ammunition and with steel-tipped pikes which he had brought with him from Kansas. After they had seized the arsenal, he urged them to start an insurrection. They captured many of the gentlemen slaveholders of this area, and then John Brown suggested that they use their pikes to "strike for freedom!" The Negroes of this area and those of the south in general did not respond to his encouragement. His band killed five people including the mayor of Harper's Ferry and a free Negro porter of the Baltimore and Ohio Railroad. On October 18, Colonel Robert E. Lee of the United States Army, who was a native Virginian, was placed in charge of the situation. James Ewell Brown Stuart (later, commonly known as "J. E. B." Stuart) was appointed aide-de-camp to Lee. Stuart was assigned the task of presenting the summons to John Brown to surrender after one hundred United States Marines had surrounded the arsenal and had captured the raiders. Stuart successfully performed his task and was admired by many Americans for his staunch courage in this action because John Brown was such an unpredictable individual. Lee then sent John Brown to Charlestown, Virginia (now located in West Virginia) where he was tried by a Virginia Circuit Court for treason and for murder because of the capture of guns and supplies belonging to the government, was found guilty and was hanged on December 2, 1859. Ten of his followers were also killed. This incident caused hostile feelings between the sections to increase and made the Virginians very angry upon finding out the extent to which some individuals would conspire to incite Negro hatred for their masters.
