During the Atlanta campaign of the Civil War, Union officers Walter Q. Gresham and Francis P. Blair Jr. of the XVII Corps reached Mableton on July 3, 1864, after the Union defeat at Kennesaw. Gresham replenished his troops' supplies and received medical care at Robert Mable's house, and camped for the night before advancing to Atlanta. The house was spared from the carnage of Sherman's March to the Sea.
