Battle of Kennesaw Mountain

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.

Sherman's 1864 campaign against Atlanta began with a series of flanking maneuvers that compelled Johnston's forces to withdraw from heavily fortified positions with minimal casualties on either side. After two months and 70 miles (110 km) of such maneuvering, Sherman's path was blocked by imposing fortifications on Kennesaw Mountain, near Marietta, Georgia. The Union general chose to change his tactics and ordered a large-scale frontal assault on June 27. Major General James B. McPherson feinted against the northern end of Kennesaw Mountain, while his corps under Major General John A. Logan assaulted Pigeon Hill on its southwest corner. At the same time, Major General George H. Thomas launched strong attacks against Cheatham Hill at the center of the Confederate line. Both attacks were repulsed with heavy losses, but a demonstration by Major General John M. Schofield achieved a strategic success by threatening the Confederate army's left flank, prompting yet another Confederate withdrawal toward Atlanta and the removal of General Johnston from command of the army.
