During the American Civil War Natchez was surrendered by Confederate forces without a fight in September 1862. Following the Union victory at the Battle of Vicksburg in July 1863, many refugees, including former slaves, freed by the Emancipation Proclamation, began moving into Natchez and the surrounding countryside. The Union Army officers claimed to be short on resources and unable to provide for the refugees. The Army planned to address the situation with a mixture of paid labor for freed slaves on government leased plantations, the enlistment of able bodied males who were willing to fight in the Union Army and the establishment of refugee camps where former slaves could be provided with education. However, as the war continued, the plan was never effectively implemented and the leased plantations were crowded, poorly managed and frequently raided by Confederate troops who controlled the surrounding territory. Hundreds of people living in Natchez, including many former slaves and refugees, died of hunger, disease, overwork or were killed in the fighting during this period.[6] In order to manage the tens of thousands of freed Black slaves, the Union Army created a concentration camp in Natchez in a natural pit known as the Devil's Punchbowl, where thousands died of starvation, smallpox, and other diseases.[7][8]
After the American Civil War, the city's economy rapidly revived, mostly due to Natchez having been spared the destruction visited upon many other parts of the South. From 1870 to 1871, Robert H. Wood served as Mayor of Natchez, he was the one of only five African Americans to served as mayor during the Reconstruction-era, and he may be the first black mayor in the entire country.[9][10][11] Natchez was also home to politians Hiram Rhodes Revels and John R. Lynch, both African Americans.
The vitality of the city and region was captured most significantly in the 80 years or so following the war by the photographers Henry C. Norman and his son Earl. The output of the Norman Studio between roughly 1870 and 1950 documents this period in Natchez's development vividly; the photographs are now preserved as the Thomas and Joan Gandy Collection in special collections of the library of Louisiana State University in Baton Rouge.
