The Battle of Fredericksburg was fought December 11–15, 1862, in and around Fredericksburg, Virginia, in the Eastern Theater of the American Civil War. The combat, between the Union Army of the Potomac commanded by Maj. Gen. Ambrose Burnside and the Confederate Army of Northern Virginia under Gen. Robert E. Lee, included futile frontal attacks by the Union army on December 13 against entrenched Confederate defenders along the Sunken Wall on the heights behind the city. It is remembered as one of the most one-sided battles of the war, with Union casualties more than twice as heavy as those suffered by the Confederates. A visitor to the battlefield described the battle as a "butchery" to U.S. President Abraham Lincoln.
The Second Battle of Bull Run or Battle of Second Manassas was fought August 28–30, 1862, in Prince William County, Virginia, as part of the American Civil War. It was the culmination of the Northern Virginia Campaign waged by Confederate Gen. Robert E. Lee's Army of Northern Virginia against Union Maj. Gen. John Pope's Army of Virginia, and a battle of much larger scale and numbers than the First Battle of Bull Run fought on July 21, 1861 on the same ground.
The Richmond–Petersburg campaign was a series of battles around Petersburg, Virginia, fought from June 9, 1864, to March 25, 1865, during the American Civil War. Although it is more popularly known as the Siege of Petersburg, it was not a classic military siege, in which a city is usually surrounded and all supply lines are cut off, nor was it strictly limited to actions against Petersburg. The campaign consisted of nine months of trench warfare in which Union forces commanded by Lt. Gen. Ulysses S. Grant assaulted Petersburg unsuccessfully and then constructed trench lines that eventually extended over 30 miles (48 km) from the eastern outskirts of Richmond, Virginia, to around the eastern and southern outskirts of Petersburg. Petersburg was crucial to the supply of Confederate Gen. Robert E. Lee's army and the Confederate capital of Richmond. Numerous raids were conducted and battles fought in attempts to cut off the Richmond and Petersburg Railroad. Many of these battles caused the lengthening of the trench lines.
The Battle of Chickamauga, fought on September 19–20, 1863, between U.S. and Confederate forces in the American Civil War, marked the end of a Union offensive, the Chickamauga Campaign, in southeastern Tennessee and northwestern Georgia.

Jackson's Valley campaign, also known as the Shenandoah Valley campaign of 1862, was Confederate Maj. Gen. Thomas J. "Stonewall" Jackson's spring 1862 campaign through the Shenandoah Valley in Virginia during the American Civil War. Employing audacity and rapid, unpredictable movements on interior lines, Jackson's 17,000 men marched 646 miles (1,040 km) in 48 days and won several minor battles as they successfully engaged three Union armies, preventing them from reinforcing the Union offensive against Richmond.
The SecondBattle of Franklin was fought on November 30, 1864, in Franklin, Tennessee, as part of the Franklin–Nashville Campaign of the American Civil War. It was one of the worst disasters of the war for the Confederate States Army. Confederate Lt. Gen.

John Schofield and was unable to prevent Schofield from executing a planned, orderly withdrawal to Nashville.

John Pope and his Army of Virginia.
The First Battle of Auburn was fought on October 13, 1863, between Union infantry and Confederate cavalry forces at the start of the Bristoe Campaign during the American Civil War. A Union infantry column stumbled upon a Confederate cavalry reconnaissance party and a short, inconclusive fight ensued. The Confederate cavalry withdrew in the face of the superior Union force, but a much larger body of Confederate cavalry under Maj. Gen. J.E.B. Stuart, attempting to raid a Union wagon train became entrapped by the column, forcing them to abandon the raid and hide in a ravine overnight awaiting Confederate infantry to come to their aid.
The Knoxville campaign was a series of American Civil War battles and maneuvers in East Tennessee during the fall of 1863 designed to secure control of the city of Knoxville and with it the railroad that linked the Confederacy east and west, and position the First Corps under Longstreet for return to the Army of Northern Virginia. Union Army forces under Maj. Gen. Ambrose Burnside occupied Knoxville, Tennessee, and Confederate States Army forces under Lt. Gen. James Longstreet were detached from Gen. Braxton Bragg's Army of Tennessee at Chattanooga to prevent Burnside's reinforcement of the besieged Federal forces there. Ultimately, Longstreet's Siege of Knoxville ended when Union Maj. Gen. William Tecumseh Sherman led elements of the Army of the Tennessee and other troops to Burnside's relief after Union troops had broken the Confederate siege of Chattanooga. Although Longstreet was one of Gen. Robert E. Lee's best corps commanders in the East in the Army of Northern Virginia, he was unsuccessful in his attempt to penetrate the Knoxville defenses and take the city.

Rosecrans's Union Army of the Cumberland at the Battle of Chickamauga in September, the Confederate Army of Tennessee under Gen. Braxton Bragg besieged Rosecrans and his men by occupying key high terrain around Chattanooga, Tennessee. Maj. Gen. Ulysses S. Grant was given command of Union forces in the West, now consolidated under the Division of the Mississippi. Significant reinforcements also began to arrive with him in Chattanooga from Mississippi and the Eastern Theater. On October 18, Grant removed Rosecrans from command of the Army of the Cumberland and replaced him with Major General George Henry Thomas.

The Battle of Philadelphia saw the Confederate cavalry brigades of Colonels J. J. Morrison and George Gibbs Dibrell attack a Union cavalry brigade under Colonel Frank Wolford at Philadelphia, Tennessee, during the Knoxville campaign of the American Civil War. While Dibrell's brigade skirmished with Wolford's cavalrymen, Morrison led his brigade around the west side of Philadelphia to attack the Union force from the rear. Wolford sent half his brigade to counter Morrison's envelopment, but Dibrell's soldiers suddenly attacked. The Confederates completely routed Wolford's troopers, capturing over 400. A Union infantry-cavalry force reoccupied Philadelphia the next day, but a week later it withdrew to the north bank of the Tennessee River, abandoning Loudon, Tennessee.
