Under Cloak of Night

February 1945. A convoy crosses a submarine-hunted Atlantic carrying the only battalion of Black women ever sent overseas by the United States Army, bound for Birmingham, England, and a mission sized for their failure. Warehouses and hangars stacked to the rafters with undelivered mail, seventeen million pieces, some of it years old, addressed to seven million Americans at war. Morale was dying in the backlog. The Army's own arithmetic said six months. The women of the 6888th were given bombed school buildings, blackout curtains, coal stoves, and the motto they made a law: no mail, low morale.

What they built in the iron cold was a machine the theater had never seen. Three shifts around the clock, seven days a week. A locator file grown toward a quarter million cards. Every soldier findable, every letter moving. They broke the six-month backlog in half the allotted time, took the inspections meant to humble them and returned them corrected, and faced down a general who threatened their commander with a sentence that entered Army legend. In a country without an American arrangement, English children watched them drill, and English mothers stopped their daughters and told them: watch how those women work, Margaret. Nobody works like that.

This is the book of the proving ground, told from inside the sorting floors, where every envelope was a soldier's lifeline and every locator card a life put back in reach of the people who loved it. A battalion the plan had rated as an experiment ran the mail of a war, sang through the night shifts of a frozen city, and made the first entry in a record the rest of this saga will spend eighty years delivering.
