Concept note-1: -Because of its location and commercial importance, Atlanta was used as a center for military operations and as a supply route by the Confederate army during the Civil War. Therefore, it also became a target for the Union army. General William Tecumseh Sherman and his troops captured the city in 1864.
Concept note-2: -Destroying the Confederacy’s railroads took away another advantage the South had over the North – land mass. By shrinking the vast space the Confederate Army could operate within, the Union was able to contain the Confederate army to a much smaller, and much more vulnerable, piece of land.
Concept note-3: -Railroads imported prosperity The railroads established Atlanta (as it became formally known in 1847) as a collection and distribution center. They hauled food, cotton, and other raw materials to Atlanta from around the Southeast for shipment north.
Concept note-4: -Railroads allowed the transportation of goods over very long distances without having to worry about horse flesh, or mules, or anything like that. You could load a train with lots of cargo and send it a very long way. As such, they became vital, strategic arteries for the armies of the Civil War.
