A historical market defines this site where, from Sept. 1864 through Feb. 1865 approximately 16,000 Union soldiers were held captive in Florence. A stockade was constructed here to accommodate prisoners, previously incarcerated at Andersonville and other prisons in south Georgia, who were moved as a result of Gen. William T. Sherman's Union Forces heading to Savannah in the now famous "March to the Sea." Approximately 2,802 Union soldiers died and many are buried as "unknowns" in the adjacent Florence National Cemetery. Plans are in the works to develop the site.
