In the fall of 1864, Gen. William T. Sherman and his army set off for the sea and the most important city at the time: Savannah. Plantation owners fled the approaching troops, but even before they did so, slaves self-emancipated to Union lines—with many as 20,000 enslaved people ultimately attaching themselves to Sherman’s army. Historian Bennett Parten, author of Somewhere Toward Freedom: Sherman's March and the Story of America's Largest Emancipation, reframes this seminal episode in Civil War history, discussing how Sherman’s still-controversial March to the Sea played a significant role in bringing the conflict to a close, due in no small part to the efforts of thousands of enslaved people who took part in it.
