As Ima Freedslave approached the witness stand, she raised her right hand, swore to tell the truth and recalled the story of how U.S. Army Gen. William T. Sherman and his troops freed her from slavery on the mayor’s plantation.“I am finally free,” she said. “General Sherman also made me a private in his army. I would not want to see him behind bars.”Her testimony did little to protect Sherman, who was later found guilty of war crimes by a jury.Despite the costumes, the recent case against Sherman in Forsyth County Magistrate Court was simply a mock trial by fifth-graders from Brookwood Elementary School.
