In September of 1864, as the American Civil War approached its conclusion, a slave-turned-soldier named Spotswood Rice wrote the following furious letter to his former owner, Katherine Diggs, and sternly warned her that she would soon be seeing him again: he was returning to Missouri, together with a thousand-strong army of black soldiers, to rescue his still-enslaved children. His anger is almost palpable.
Indeed, Spotswood Rice was reunited with his family some months later, although it's unknown whether a showdown with Diggs occurred. Interestingly, Mary, the daughter mentioned in the letter, was interviewed as part of the Federal Writers' Project in 1937.
