The U.S. Senate orders arrest of 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 right to force testimony and punish witnesses who failed to appear. The U.S. Senate on this day ordered his arrest. He was sent to the Washington Jail on March 12, 1860. (By John Osborne)
