From USNI News:
A guided-missile cruiser that was named after a Confederate Civil War victory will be renamed in honor of a former slave who stole a Confederate States Navy ship in South Carolina and delivered it to the Union, the Navy announced in a late Monday statement.
USS Chancellorsville (CG-62) will be renamed after Robert Smalls, a former slave who was conscripted into Confederate service in 1862. The skilled navigator stole the steamer CSS Planter and escaped from Charleston on May 13, 1862, with his family, rescuing enslaved people and capturing military material. He turned the ship over to the U.S. Navy."
