The 6888th Central Postal Directory Battalion was an all-Black, all-female battalion of the Women's Army Corps that served during World War II. The unit was created to address the backlog of mail to and from American soldiers stationed in Europe, particularly Black American soldiers, who had been waiting months, and sometimes years, to receive letters from their loved ones. The 6888th was tasked with sorting and delivering this mail, a task that required tremendous skill, organization, and dedication. The unit overcame significant obstacles, including segregation and discrimination, to accomplish its mission, working around the clock for months to deliver millions of pieces of mail. The women of the 6888th helped to strengthen morale and support for the war effort among Black American soldiers and their families.
