Battle - Vicksburg - Vicksburg, Mississippi
In mid-May, 1863, after six months of unsuccessful attempts, Maj. Gen. Ulysses S. Grant's Army of the Tennessee finally converged on Vicksburg, defended by a Confederate army under Lt. Gen. John C. Pemberton. Capture of the Mississippi River town was critical to Union control of the strategic river. Vicksburg was located on a high river bluff defended with artillery, and Pemberton's men had constructed a series of fortifications in an 8-mile arc surrounding the city on the landward side. After crossing the…READ MORE

Battle - Chickamauga - Catoosa County, Georgia; Walker County, Georgia
After the successful Tullahoma Campaign, Maj. Gen. William Rosecrans continued the Union offensive, aiming to force Gen. Braxton Bragg's Confederate army out of Chattanooga. Through a series of skillful marches towards the Confederate-held city, Rosecrans forced Bragg out of Chattanooga and into Georgia. Determined to reoccupy the city, Bragg followed the Federals north, brushing with Rosecrans' army at Davis' Cross Roads. While they marched on September 18th, his cavalry and infantry skirmished with Un…READ MORE

Battle - Chattanooga Campaign - Chattanooga, Tennessee
After taking charge of the Union's western armies in October of 1863, Maj. Gen. Ulysses S. Grant focused on lifting the Confederate siege of Chattanooga, Tennessee, which had been in place since the Battle of Chickamauga in September. Grant opened the 'Cracker Line' across the Tennessee River to bring supplies to the beleaguered Army of the Cumberland inside the city, and, in mid-November, brought Maj. Gen. William T. Sherman's Army of the Tennessee into the city as well. The Confederates under Maj. Gen.…READ MORE

Battle - Missionary Ridge - Chattanooga, Tennessee
From the last days of September through October 1863, Gen. Braxton Bragg's army laid siege to the Union army under Maj. Gen. William Rosecrans at Chattanooga, cutting off its supplies. On October 17, Maj. Gen. Ulysses S. Grant received command of the Western armies; he moved to reinforce Chattanooga and replaced Rosecrans with Maj. Gen. George Thomas. A new supply line was soon established. Maj. Gen. William T. Sherman arrived with his four divisions in mid-November, and the Federals began offensive operat…READ MORE

Battle - Resaca - Gordon County, Georgia; Whitfield County, Georgia
Following his withdrawal from Rocky Face Ridge, the first battle in Maj. Gen. William T. Sherman's campaign against Atlanta, Confederate Gen. Joseph E. Johnston established a four-mile defensive position protecting the Western & Atlantic Railroad west and north of Resaca, where the railroad crossed the Oostanaula River. On May 13th, Sherman tested the Rebel lines, sending forward divisions to skirmish with the Confederates, with little substantive result. On the 14th, the fighting erupted into a full-…READ MORE

Battle - New Hope Church - Paulding County, Georgia
During early May 1864, Maj. Gen. William T. Sherman successfully outmaneuvered the army of Gen. Joseph E. Johnston in multiple battles in northwest Georgia. Each time, Johnston fell back to a new defensive position closer to the strategic Confederate city of Atlanta. After Johnston retreated to Allatoona Pass on May 19-20th following the battle at Adairsville, Sherman determined to move around Johnston's left flank rather than attack the strong Confederate defenses in his front. On May 23rd, Sherman set in…READ MORE

During early and mid-May 1864, Maj. Gen. William T. Sherman successfully outmaneuvered the army of Gen. Joseph E. Johnston in multiple battles in northwest Georgia. Each time, Johnston fell back to a new defensive position closer to the strategic Confederate city of Atlanta. Stopped at New Hope Church on Johnston's left on May 26th, Sherman attacked Johnston's right at Pickett's Mill on May 27th. The next day, Lt. Gen. William J. Hardee's corps probed the Union defensive line, held by Maj. Gen. John A. Log…READ MORE

Battle - Kennesaw Mountain - Cobb County, Georgia
Fearing envelopment northwest of Atlanta, Confederate Gen. Joseph E. Johnston withdrew his army to a new defensive position astride Kennesaw Mountain near Marietta. Johnston selected this position in order to protect the Western & Atlantic Railroad, his supply link to Atlanta. Prior to taking up this new line on June 19th, Johnston had pioneers working through the night digging trenches and erecting fortifications, turning Kennesaw into a formidable earthen fortress. Having defeated Lieut. Gen. John…READ MORE

Battle - Peachtree Creek - Fulton County, Georgia
Weary of Gen. Joseph E. Johnston's pattern of retreat through northwest Georgia in the face of Maj. Gen. William T. Sherman's advancing armies, President Jefferson Davis removed him from command of the Army of Tennessee, replacing him with Lieut. Gen. John B. Hood. On July 20th, Hood determined to take the fight to the enemy by setting upon an isolated portion of Sherman's forces in front of Atlanta. Hood's target would be the Union corps of Maj. Gens. Oliver O. Howard and Joseph Hooker from Maj. Gen. Geo…READ MORE

Battle - Atlanta - Fulton County, Georgia; DeKalb County, Georgia
Despite the defeat at Peach Tree Creek, Confederate Lieut. Gen. John Bell Hood still had hopes of driving Maj. Gen. William T. Sherman's Yankees from the outskirts of Atlanta with an offensive blow. On the night of July 21, 1864, Hood ordered Lt. Gen. William J. Hardee's corps to make 15-mile night march and assault the Union left flank east of the city, held by Maj. Gen. James B. McPherson's Army of the Tennessee. Joining the attack with Hardee would be the corps of Maj. Gen. Benjamin Cheatham. Hood attac…READ MORE

Battle - Jonesborough - Clayton County, Georgia
By late August 1865, the city of Atlanta was not yet subdued by Maj. Gen. William T. Sherman's armies. A few supply lines remained open to the city supporting the army of Lieut. Gen. John B. Hood encircled there. Union cavalry raids inflicted only superficial damage, quickly repaired by the Confederates. Sherman determined that if he could destroy the Macon & Western and Atlanta & West Point Railroads to the south the Rebel army would be forced to evacuate the city. On August 25, Union infantry beg…READ MORE

Battle - Nashville - Nashville, Tennessee
Despite a series of defeats in the closing days of November, 1864, Confederate Lieut. Gen. John Bell Hood continued to drag his bloodied Army of Tennessee, approximately 30,000 strong, north towards Nashville. The city was protected by 55,000 Union soldiers, which should have precluded further offensive operations, but Hood was determined and his situation was dire. Hood reached Nashville on December 2nd and staked out a position south of the city, hoping to draw the Union forces into a costly attack. Ulys…READ MORE

Battle - Bentonville - Bentonville, North Carolina
After his march to the sea, Maj. Gen. William T. Sherman headed north in early 1865 to unite with Lt. Gen. Ulysses S. Grant's army in Virginia. Only Confederate Gen. Joseph Johnston's army stood between Sherman and Grant. After briefly blocking Sherman's advance at Averasboro, North Carolina on March 16, Johnston struck Maj. Gen. Henry Slocum's wing of Sherman's army near Bentonville on March 19. The Confederates ran into stiff resistance, as Slocum established a defensive position. Johnston's assaults con…READ MORE
