In Washington, the accused Lincoln Assassination plotters all plead not guilty before their military court

The nine officers of the Commission to try the accused plotters - seven generals and two colonels - had been named on May 6, 1865.  Two originally named men, General Cyrus B. Comstock and Colonel Horace Porter, were later relieved and replaced with General James Ekin and Colonel C.H. Tompkins.  The Commission was sworn this day, the various charges read, and the accused asked to plead.  All plead "not guilty."  (By John Osborne)
