The Kansas Civil War continues: In retaliation for the Sack of Lawrence, John Brown, an Ohio abolitionist, leads his four sons and two others in the murders of five pro-slavery settlers in Pottawatomie, federal enclave of Kansas.
NOTE: In the two years before this event, there had been eight murders in the federal enclave of Kansas over the issue of slavery; as a result, passions had become inflamed to the point that 29 Kansans lost their lives over the next three months.
