Clothing Warehouse, Chattanooga, photographed by George N. Barnard (American, 1819 - 1902). Negative about 1864; albumen silver print from 1865. During the Civil War, the Quartermaster's department hired George Barnard to record the unprecedented production, transportation, and storage of materials being requisitioned to equip the Union army. At the start of the campaign that would become famous as General Sherman's march to the sea, Barnard documented rows of Chattanooga warehouses where supplies were being amassed. Looking like innocuous barns, the vertical board and batten storage buildings reveal little of their function or content.
