By 1945, millions of Americans were serving in Europe, and their mail wasn't getting through all that well. Letters & packages from home had piled up in warehouses for months, and it was dragging down the morale of the troops. The Army's answer was the 6888th Central Postal Directory Battalion, the only all-Black battalion in the Women's Army Corps & the only all-Black, all-women battalion sent overseas in World War II. More than 800 women volunteered, under Major Charity Edna Adams. They trained at Fort Oglethorpe, Georgia, crossed the Atlantic on the Ile de France, and went to work in Birmingham, England, digging through mountains of undelivered mail. The battalion ran entirely on its own, with its own medics, cooks & administrators. I think mail sounds like a small thing until you picture being thousands of miles from home for years with nothing arriving. For a lot of those soldiers, a letter was everything. It took a long time for them to get their due: a monument at Fort Leavenworth in 2018, and the Congressional Gold Medal in 2022. Personally, I'd put them in every history textbook in the country.
