Just when you thought every American story about World War II had been told, along comes the 6888 Central Postal Directory Battalion (The SixTripleEight), the only all-black female unit to serve in Europe during the war. Led by the highest-ranking black female in the Army, they faced racism, sexism, and the Nazis.The documentary includes interviews with the surviving seven members of the 855 women of the SixTripleEight.Their mission was to clear the backlog of mail stuck in warehouses in Birmingham, England and Rouen, France. They completed this enormous task in six months distributing over 17 million pieces of mail. Their story was hidden in American military history until now.
