There are two main reasons why Atlanta was a particularly important goal for the Union in the Civil War. First, it was the main industrial center for the Confederacy. It had many factories and other facilities that were important for producing supplies for the Confederate army. Second, Atlanta was also a major rail hub. Railroads ran out from Atlanta to all parts of the Confederacy. If the Union could take Atlanta, it could cut the various parts off from one another by cutting their rail lines. For these reasons, Atlanta was an important Union target.
