American Civil War: General Sherman's frontal assault against the Confederate Army of Tennessee failed, but did not stop the Union army from advancing on Atlanta.

The American Civil War was a civil war in the United States between the Union and the Confederacy, which was formed in 1861 by states that had seceded from the Union. The central conflict leading to war was a dispute over whether slavery should be permitted to expand into the western territories, leading to more slave states, or be prohibited from doing so, which many believed would place slavery on a course of ultimate extinction.

William Tecumseh Sherman was an American soldier, businessman, educator, and author. He served as a general in the Union Army during the American Civil War (1861–1865), earning recognition for his command of military strategy but criticism for the harshness of his scorched-earth policies, which he implemented in his military campaign against the Confederate States. British military theorist and historian B. H. Liddell Hart declared that Sherman was "the most original genius of the American Civil War" and "the first modern general".

The Battle of Kennesaw Mountain was fought on June 27, 1864, during the Atlanta Campaign of the American Civil War. The most significant frontal assault launched by Union Major General William T. Sherman against the Confederate Army of Tennessee under General Joseph E. Johnston, it produced a tactical defeat for the Union forces but failed to deliver the result that the Confederacy desperately needed: a halt to Sherman's advance on Atlanta, Georgia.

The Army of Tennessee was a field army of the Confederate States Army in the Western Theater of the American Civil War. Named for the Confederate state of Tennessee, It was formed late in 1862 in Tennessee and fought until the end of the civil war, participating in most of the significant battles in the Western Theater.
