John Brown led 22 Men in a raid on Harper's Ferry, where there was a Federal Arsenal. Brown wanted to capture the weapons and ammunition and distribute them to Slaves, hopefully creating an Army in the South that would demand Slave Owners set them and others free. Brown and his men did manage to get the weapons, but were defeated by a group of US Marines. Many Men died during the fight, including two of Brown's Sons. Brown was found guilty of treason and sentenced to death. His hanging was on December 2, 1859. After his death, many Northerners saw Brown as a Martyr or hero, they were worried that the Government was being dominated by Southern Slave Owners. This was a issue in the election of 1860, and contributed to the start of the War.
