The U.S. Senate imprisons Thaddeus Hyatt for failure to appear before Harpers Ferry Committee
Thaddeus Hyatt, President of the National Kansas Aid Committee and known associate of John Brown, had been called to testify before the Senate Committee investigating the Harpers Ferry Raid. He had continually called into question the Senate's rights to force his testimony. The U.S. Senate disagreed and on a vote of 44-10 ordered him incarcerated. He was sent to the Washington Jail and not freed until June 15, 1860. (By John Osborne)
