On July 16, 1863, Confederate forces slipped out of Jackson during the night and retreated across the Pearl River. Union forces completely burned the city after its capture this second time, and the city earned the nickname "Chimneyville" because only the chimneys of houses were left standing. The northern line of Confederate defenses in Jackson during the siege was located along a road near downtown Jackson, now known as Fortification Street.

Jackson has been called Chimneyville ever since Sherman burned it to the ground, everything, when the Union troops passed through near the end of the Civil War. Our craftman's guild in the state is called the Chimneyville Craftman's Guild.
