BOSTON (AP) – An all-black Civil War infantry unit depicted in the Academy Award-winning moving “Glory,” starring Denzel Washington, is making a real-life comeback.The 54th Massachusetts Volunteer Infantry was reactivated Friday at a Statehouse ceremony and redesignated as the Massachusetts National Guard’s ceremonial unit, which renders military honors at funerals and state functions.The revival pays homage to the group of black soldiers who fought on behalf of the state in the Civil War.Some of those men came from Lynn and their photographs hang on the walls of the Grand Army of the Republic building on Andrew Street.John Stackhouse joined the 54th at the age of 30. Joseph Butler and William Robinson fought at Fort Wagner, the battle depicted in Glory, a movie homage to the 54th. They were laborers and carpenters before they became soldiers. Some, like John Snowden, died of disease before the war ended.The unit won praise for its doomed charge on Battery Wagner in South Carolina in 1863 and produced the nation’s first black Medal of Honor winner, Sgt. William Carney.It was deactivated after the Civil War and its colors were retired.The 1989 movie “Glory,” based on the letters of the unit’s commander Colonel Robert G. Shaw, depicted the prejudice the unit and Shaw faced. The film was honored with three Academy Awards, including best supporting actor for Washington.
