In Washington, John Wilkes Booth's accused fellow plotters are transferred to the Old Penitentiary for trial
The accused co-conspirators in John Wilkes Booth's plot against the life of President Lincoln were removed from the Washington Navy Yard, where they had been held aboard navy ships, to the Old Penitentiary building in the grounds of the Washington Arsenal. All seven were held in seperate cells and all but Mrs. Surratt were constantly hooded and shackled. The defendents pleased not guilty on May 11, 1865 and the trial began in earnest the next day.
