During the Civil War, control of the railroad was vital to the protection of Savannah and keeping nearby Confederate troops supplied with food and materiel. In December 1864, during his March to the Sea, Maj. Gen. William T. Sherman sent part of his Union forces forward to cut the line, which would force Confederate general William Hardee to retreat and abandon Savannah. The mission failed, but sections of the railroad would be severely damaged during Sherman's subsequent 1865 Carolinas Campaign.
