During the Atlanta Campaign, General Wiliam Tecumseh Sherman maneuvered General Joseph E. Johnston's Confederate army out of several successive defensive positions in Cobb County. Sherman first found Johnston's army entrenched in the Marietta area on June 9. The Confederate's had established defensive lines along Brushy, Pine, and Lost Mountains but Sherman extended his forces beyond the Confederate lines, causing a partial Rebel withdrawal. After further pressure and skirmishing from Union forces, Johnston withdrew to an arc-shaped position centered on Kennesaw Mountain on June 18 and 19. Repulsed several times, Sherman eventually extended the line on his right and forced Johnston to withdraw from the Marietta area on July 2-3.
