Battle of Atlanta

July 22, 1864

The Battle of Atlanta was fought between the United States of America and the Confederate States of America on July 22, 1864, near Atlanta, Georgia. Union forces under General William T. Sherman defeated Confederate forces under General John B. Hood after Hood launched attacks against the Union left flank and center. Although Confederate forces still held Atlanta after the battle, Hood’s army suffered heavy losses, and Sherman later forced the evacuation of the city.

Overview

The Battle of Atlanta was fought on July 22, 1864, in Fulton County, near Atlanta, Georgia, during the American Civil War. It was part of the Atlanta Campaign and followed months of fighting between Union and Confederate forces in northern Georgia. 

After Union forces broke the Confederate siege of Chattanooga in late November 1863, Major General William T. Sherman led three Union Armies south from Tennessee in pursuit of General Joseph E. Johnston’s Army of Tennessee.

Sherman repeatedly used flanking movements to threaten the Western and Atlantic Railroad, forcing Johnston to retreat toward Atlanta. By mid-July, Sherman had pushed Johnston’s army to the outskirts of the city. Confederate President Jefferson Davis removed Johnston from command on July 17, 1864, and replaced him with General John B. Hood, who quickly launched attacks against Union forces.

After a costly failure at Peachtree Creek on July 20, Hood attacked General James B. McPherson’s Army of the Tennessee east of Atlanta on July 22. Confederate forces struck the Union left flank and later the Union center, but failed to break the line. McPherson was killed during the battle, but Union forces regrouped, counterattacked, and won. Hood’s army suffered about 8,500 casualties, while Union losses totaled about 3,600.

Significance

The Battle of Atlanta is important to American History because it was a major Union victory during William T. Sherman’s Atlanta Campaign. Sherman’s forces held their lines against John Bell Hood’s attacks on the Union left flank and center, even after Confederate soldiers killed General James B. McPherson. Hood’s army suffered heavy casualties, weakening Confederate forces defending Atlanta. Although the Confederates still held the city after the battle, their position became difficult to maintain. Sherman then settled into a siege, shelled Atlanta, and cut off supplies until Hood evacuated the city six weeks later.

History

Federal Breakout from Chattanooga

In late November 1863, Union forces commanded by Major General Ulysses S. Grant successfully lifted Confederate General Joseph E. Johnston’s siege of Chattanooga, Tennessee. Union victories at the Battle of Lookout Mountain (November 24) and the Battle of Missionary Ridge (November 25) forced Johnston to withdraw thirty miles south near Dalton, Georgia.

Grant Promoted to Lieutenant General

After the Federal breakout from Chattanooga, President Abraham Lincoln promoted Grant to the special rank of Lieutenant General and placed him in command of all Union armies. Grant moved his headquarters to Washington, leaving his trusted subordinate, Major General William T. Sherman, in command of federal operations in the western theater.

Grant’s Umbrella Strategy

Grant’s primary military strategy was a coordinated effort to attack and defeat the two main Confederate armies in the field, Robert E. Lee and the Army of Northern Virginia in the east, and Joseph E. Johnston and the Army of Tennessee in the west.

On May 5, 1864, Grant launched his Overland Campaign against Lee in Virginia. Two days later, Sherman led three armies, the Army of the Tennessee, commanded by Major General James B. McPherson; the Army of the Ohio, commanded by Major General John M. Schofield; and the Army of the Cumberland, commanded by Major General George H. Thomas, out of Tennessee in pursuit of Johnston’s army in northern Georgia.

Sherman Moves South

Throughout the summer of 1864, the Confederate and Union armies engaged in a series of battles between Dalton and Atlanta in northern Georgia. Most of the fighting occurred at places on or near the Western and Atlantic Railroad, which connected Chattanooga and Atlanta. Both sides depended on the railway for supplies throughout the campaign. In a pattern that Sherman often repeated, he used flanking movements that threatened the railway to Johnston’s rear, forcing the Confederate commander to retreat south to protect his supply lines.

Hood Replaces Johnston

By mid-July, Sherman had driven Johnston’s army to the outskirts of Atlanta. Southerners, in general, and Jefferson Davis, in particular, had grown weary of Johnston’s strategy of retreat. On July 17, 1864, the Confederate President relieved Johnston of his command, replacing him with General John Bell Hood. Known as an aggressive fighter, Hood was a veteran officer with a reputation for personal bravery. He received severe wounds at the Battle of Gettysburg (July 1–3, 1863) and at the Battle of Chickamauga (September 19–20, 1863). Upon assuming his new command, General Hood wasted little time in responding to Southerners’ calls for action.

Peachtree Creek

On July 20, Hood launched a costly attack against the Army of the Cumberland. The assault cost Hood nearly 5,000 soldiers and did not drive the Federals back north of Peachtree Creek. Undeterred, Hood turned his attention to McPherson’s Army of the Tennessee, east of Atlanta.

Engagement at Atlanta

On July 22, Hood ordered William J. Hardee’s corps to march out and assault McPherson’s left flank, which Hood believed was vulnerable. Unfortunately for Hood, McPherson recognized the weakness on his left flank and reinforced it before Hardee arrived to launch his assault. The battle began when Hardee’s soldiers encountered McPherson’s reinforcements. The Federals repulsed the initial attack but gradually began to give ground. Confederate soldiers shot and killed McPherson, who rode to the front to observe the fighting. Despite the loss of their leader, the Union forces regrouped and eventually held their line.

At about 4 p.m., Hood launched a secondary assault against the Union center. Once again, the initial push was successful, and the Confederates forced the Federals back. In response, Sherman personally directed artillery fire on the Confederates, halting their surge and inflicting heavy casualties. The Federals then launched a counterattack and restored their lines. With the Union lines stabilized on both fronts and Confederate losses rising to unacceptable levels, Hood called off the attacks.

Aftermath of the Battle

The Battle of Atlanta was another costly defeat for the Confederacy. Hood’s army lost 8,500 killed, wounded, captured, or missing badly needed soldiers. Union losses totaled about 3,600, including McPherson. The Confederates still held Atlanta, but their situation was untenable. Sherman settled into a siege, shelling the city, and cutting off supplies until Hood had to evacuate Atlanta six weeks later.
