The Battle of Atlanta took place on July 22, 1864, during the Atlanta campaign of the American Civil War, occurring just southeast of Atlanta, Georgia. Union forces under William T. Sherman were continuing their summer campaign to capture Atlanta, an important rail and supply hub for the Confederacy. The engagement represented a critical moment in the Union's effort to seize this strategically vital city, though it would later be understood as occurring midway through the broader campaign rather than as the decisive final blow its name might suggest.
The battle saw Union forces commanded by William T. Sherman overwhelm and defeat Confederate forces under John B. Hood's command. A particularly significant casualty was Union Major General James B. McPherson, who was killed during the battle. McPherson's death made him the second-highest-ranking Union officer killed in action during the entire war, underscoring the intensity and stakes of the engagement.
Despite the Union victory at Atlanta, the city itself did not fall until September 2, 1864, following a Union siege and various attempts to seize the railroads and supply lines that sustained Confederate operations in the area. The eventual fall of Atlanta carried profound political ramifications, occurring in 1864 as the presidential election approached. The Union victory boosted President Abraham Lincoln's political position as he faced Democratic challenger George B. McClellan, a former Union General, whose party's platform called for an armistice with the Confederacy. After taking the city, Sherman's forces continued their campaign southward toward Milledgeville, Georgia's state capital, and ultimately toward Savannah in what became known as the March to the Sea.
The American Civil War (1861–1865) was the deadliest conflict in American history, killing an estimated 620,000 to 750,000 soldiers and an unknown number of civilians. The Confederate States of America, formed by eleven seceding Southern states, faced the Union in four years of warfare across 23 states and territories. Major engagements included First and Second Bull Run, Antietam (the bloodiest single day in American history, September 17, 1862), Chancellorsville, Gettysburg (July 1–3, 1863), Vicksburg (surrendered July 4, 1863), and Sherman's March through Georgia and the Carolinas (1864–1865). President Lincoln issued the Emancipation Proclamation on January 1, 1863, transforming the war's stated purpose to include the abolition of slavery and enabling the enlistment of approximately 180,000 Black men in the United States Colored Troops. Confederate General Robert E. Lee surrendered to Ulysses S. Grant at Appomattox Court House on April 9, 1865. The war resolved the question of secession and ended American slavery, though Reconstruction would face sustained resistance in its attempt to secure civil rights for formerly enslaved people.
