Union headquarters at 26 South Battery Street in occupied Charleston, South Carolina, 1865 (b/w photo)

Union Maj.-Gen. John P. Hatch’s headquarters in the villa at 26 South Battery Street in occupied Charleston, South Carolina, guarded by African-American soldiers; note the American flag at half-staff and bunting on the mansion’s arcade columns, as a sign of mourning for the recent assassination of President Lincoln in April 1865. The adjacent mansion, at 28 South Battery to the left of this picture, was the home of photographer George S. Cook, and also has bunting displayed on its columns, although the house itself was still shuttered awaiting his return to reoccupy it with his family. Both buildings still stand largely unchanged today, part of a historic-preservation effort in the City of Charleston. This image was enhanced by combining its stereographic pair of wet-collodion glass negatives into a single wide photograph, cleaned and repaired
