The abolitionist John Brown had already fought against pro-slavery forces in Bleeding Kansas for several years when he decided to lead a raid on a Federal arsenal in Harpers Ferry, Virginia. This raid was a joint attack by former slaves, freed blacks, and white men who had corresponded with slaves on plantations in order to create a general uprising among slaves. Brown carried hundreds of copies of the constitution for a new republic of former slaves in the Appalachians. But they were never distributed, and the slave uprisings that were to have helped Brown did not happen. Some believe that he knew the raid was doomed but went ahead anyway, because of the support for abolition it would (and did) generate. The U.S. military, led by Lieutenant Colonel Robert E. Lee, easily overwhelmed Brown's forces. But directly following this, slave disobedience and the number of runaways increased markedly in Virginia.
