Reverdy Johnson, congressman and leading Maryland figure, visited Mr. Surratt in her cell at the Old Washington Penitentiary and after their discussion offered his services as a member of her defense team.  Her other lawyers were Frederick Aiken and John W. Clampitt.  All their efforts were in vain, however, in the current atmosphere.  Mary Surratt was sentenced to death as an accessory to murder on July 6, 1865 and hanged the next day, still protesting her innocence.  (By John Osborne) 

Captain John Quincy Marr of the Warrenton Riflemen was killed by small arms fire during the cavalry reconnaisance of Second Lieutenant Charles H. Tompkins and his troop of regular U.S. dragoons scouting Fairfax Court House in Virginia.  Marr was a 1846 V.M.I graduate who had later became sheriff of Fauquier County and then sat as a delegate at the Virginia Secession Convention.  The only death in the small but sharp encounter, he became the first commissioned Confederate officer to die in the conflict. He was thirty-five years old. (By John Osborne)
