November 1864: As the Civil War rolls into its fourth bloody year, the tide has turned decidedly in favor of the Union. A grateful Abraham Lincoln responds to Ulysses S. Grant's successes by bringing the general east, promoting Grant to command the entire Union war effort, while William Tecumseh Sherman now directs the Federal forces that occupy all of Tennessee. In a massive surge southward, Sherman conquers the city of Atlanta, sweeping aside the Confederate army under the inept leadership of General John Bell Hood. Pushing through northern Georgia, Sherman's legendary "March to the Sea" shoves away any Rebel presence, and by Christmas 1864 the city of Savannah falls into the hands of "Uncle Billy." Now there is but one direction for Sherman to go. In his way stands the last great hope for the Southern cause, General Joseph E. Johnston.
