The following engagements took place in the year 1863 during the American Civil War. During the year, Union forces captured the Confederate cities of Vicksburg and Port Hudson, giving them complete control over the Mississippi River, while forcing Confederates out of the North following the Battle of Gettysburg.
In the Eastern theater, the Union Army of the Potomac, commanded by Major General Joseph Hooker, attacked the Confederate Army of Northern Virginia commanded by General Robert E. Lee in the Battle of Chancellorsville. Hooker planned to move most of his army around to the Confederates's rear before Lee could react and force Lee to retreat but the Union army was slowed and then stopped by a small Confederate force, which was reinforced by the rest of the Confederate army. Lee then sent a flanking column led by Thomas J. Jackson around Hooker's left, which attacked a few hours before sunset on May 2; this attack and further Confederate attacks the following day forced Hooker to retreat on May 6. During the battle, Jackson was wounded by friendly fire and died several days later. [1] Lee reorganized his army following the campaign and launched an invasion of Union territory in June, moving through the Shenandoah Valley into Pennsylvania; Hooker was relieved of command on June 29, due to continuous disputes with the government over the garrison of Harpers Ferry, and replaced by Major General George Meade. During the Battle of Gettysburg from July 1 to July 3, Meade successfully held off Lee's attacks while inflicting heavy casualties in return. Lee was forced to retreat back to Virginia; Meade followed in close pursuit but was unable to find an opportunity to completely crush the Confederate army. [2] In October, Lee attempted to isolate and destroy Meade during the Bristoe Campaign but failed in an attack on Union positions at the Battle of Bristoe Station on October 14. Pressed by Union authorities, Meade also tried to attack Lee's positions along the Mine Run; however, Lee was able to establish a fortified defensive line across the Union line of advance. Meade judged the Confederate position too strong to attack and retreated. [3]
In the Western Theater, simultaneous Union offensives from northern Mississippi and eastern Louisiana resulted in the sieges of Vicksburg and Port Hudson, both along the Mississippi River. Ulysses S. Grant started the Vicksburg campaign near the end of April when he crossed the Mississippi River near Bruinsburg Landing, south of Grand Gulf. He then marched inland and captured the Mississippi state capital of Jackson before turning east to Vicksburg; this isolated the Confederate garrison from Confederate supplies and reinforcements. After a six-week siege, the Confederate garrison surrendered on July 4, followed by the surrender of Port Hudson on July 9; this resulted in the complete Union control of the Mississippi River and made Grant a hero in the North. [4] In central Tennessee, the Union Army of the Cumberland commanded by Major General William S. Rosecrans maneuvered the Confederate Army of Tennessee, commanded by General Braxton Bragg, towards Chattanooga, Tennessee during the Tullahoma Campaign from late June to early July. In early September, Rosecrans launched another offensive which resulted in the capture of Chattanooga, an important Confederate rail center; however, a few weeks later Bragg, reinforced with James Longstreet's corps from the Army of Northern Virginia, attacked Rosecrans near the Chickamauga Creek and routed much of the Union army, forcing it to retreat back to Chattanooga. Stubborn resistance from the troops of George H. Thomas prevented the Confederates from launching an immediate pursuit. [5] Bragg settled his army into a siege of Chattanooga, almost completely cutting off all supplies to the Union army. Soon, dissension and arguments began to create tension in the Confederate army's high command; this resulted in Longstreet being sent to eastern Tennessee and a reorganization of the army in an attempt by Bragg to rid the army of his critics. Grant, promoted to command of the Military Division of the Mississippi, took command of the Union forces near the city, which was reinforced by the Army of the Tennessee and a detachment from the Army of the Potomac. During the three days from November 23 to the 26, Grant launched a series of attacks on the Confederate positions and was able to drive off Bragg's army. A rear guard action by Patrick Cleaburne at Ringgold Gap halted the Union pursuit long enough for Bragg to reach safety. A few weeks after the battle, Bragg was relieved of command by his own request. [6]
In the Trans-Mississippi Theater, only small battles and skirmishes took place. On January 1, Confederate forces led by Major General John B. Magruder recaptured the port city of Galveston, the only port city which the Confederates were able to recapture during the war. In order to cut off the Trans-Mississippi supply lines to Port Hudson, Major General Nathaniel P. Banks moved up the Bayou Teche in Louisiana during April. For the remainder of the summer, Confederate commander Major General Richard Taylor attempted to cut off Banks' supply lines to New Orleans but failed. In September, Union forces tried to invade eastern Texas to counteract the French invasion of Mexico but were defeated at Sabine Pass, losing two gunboats and 350 men while the Confederates suffered no casualties.

The Battle of Gettysburg was a three-day battle in the American Civil War fought between Union and Confederate forces between July 1 and July 3, 1863, in and around Gettysburg, Pennsylvania. The battle, which was won by the Union, is widely considered the Civil War's turning point, ending the Confederacy's aspirations to establish an independent nation. It was the Civil War's bloodiest battle, claiming over 50,000 combined casualties over three days.
James Ewell Brown "Jeb" Stuart was a Confederate States Army general during the American Civil War. He was known to his friends as "Jeb,” from the initials of his given names. Stuart was a cavalry commander known for his mastery of reconnaissance and the use of cavalry in support of offensive operations. While he cultivated a cavalier image, his serious work made him the trusted eyes and ears of Robert E. Lee's army and inspired Southern morale.
George Gordon Meade was a United States Army Major General who commanded the Army of the Potomac during the American Civil War from 1863 to 1865. He fought in many of the key battles of the Eastern theater and defeated the Confederate Army of Northern Virginia led by General Robert E. Lee at the Battle of Gettysburg.
John Fulton Reynolds was a career United States Army officer and a general in the American Civil War. One of the Union Army's most respected senior commanders, he played a key role in committing the Army of the Potomac to the Battle of Gettysburg and was killed at the start of the battle.
The Army of Tennessee was the principal Confederate army operating between the Appalachian Mountains and the Mississippi River during the American Civil War. It was formed in late 1862 and fought until the end of the war in 1865, participating in most of the significant battles in the Western Theater.
The following is a list of engagements that took place in 1862 during the American Civil War. During the summer and early spring of the year, Union forces gained several successes over the Confederacy, seizing control of Missouri, northern Arkansas, Kentucky, and western Tennessee, along with several coastal areas. Confederate forces defended the capital of Richmond, Virginia, from Union assaults, and then launched counter–offensives into Kentucky and Maryland, both of which end in Union victories.
The Battle of Brandy Station, also called the Battle of Fleetwood Hill, was the largest predominantly cavalry engagement of the American Civil War, as well as the largest ever to take place on American soil. It was fought on June 9, 1863, around Brandy Station, Virginia, at the beginning of the Gettysburg Campaign by the Union cavalry under Maj. Gen. Alfred Pleasonton against Maj. Gen. J. E. B. Stuart's Confederate cavalry.
There is widespread disagreement among historians about the turning point of the American Civil War. A turning point in this context is an event that occurred during the conflict after which most modern scholars would agree that the eventual outcome was inevitable. The near simultaneous Battle of Gettysburg in the east and fall of Vicksburg in the west, in July 1863 is widely cited as the military climax of the American Civil War. Several other decisive battles and events throughout the war have been proposed as turning points. The events are presented here in chronological order with only the positive arguments for each given.
Alfred Pleasonton was a United States Army officer and major general of volunteers in the Union cavalry during the American Civil War. He commanded the Cavalry Corps of the Army of the Potomac during the Gettysburg campaign, including the largest predominantly cavalry battle of the war, Brandy Station. In 1864, he was transferred to the Trans-Mississippi theater, where he defeated Confederate General Sterling Price in two key battles, including the Battle of Mine Creek, the second largest cavalry battle of the war, effectively ending the war in Missouri. He was the son of Stephen Pleasonton and younger brother of Augustus Pleasonton.
The Gettysburg campaign was a military invasion of Pennsylvania by the main Confederate army under General Robert E. Lee in summer 1863. It was the first time during the war the Confederate Army attempted a full-scale invasion of a free state. The Union won a decisive victory at Gettysburg, July 1–3, with heavy casualties on both sides. Lee managed to escape back to Virginia with most of his army. It was a turning point in the American Civil War, with Lee increasingly pushed back toward Richmond until his surrender in April 1865. The Union Army of the Potomac was commanded by Maj. Gen. Joseph Hooker and then by Maj. Gen. George G. Meade.
The first day of the Battle of Gettysburg during the American Civil War took place on July 1, 1863, and began as an engagement between isolated units of the Army of Northern Virginia under Confederate General Robert E. Lee and the Army of the Potomac under Union Maj. Gen. George G. Meade. It soon escalated into a major battle which culminated in the outnumbered and defeated Union forces retreating to the high ground south of Gettysburg, Pennsylvania.
On the third day of the Battle of Gettysburg during the disastrous infantry assault nicknamed Pickett's Charge, there were two cavalry battles: one approximately three miles (5 km) to the east, in the area known today as East Cavalry Field, the other southwest of the [Big] Round Top mountain.
The western theater of the American Civil War encompassed major military operations in the states of Alabama, Georgia, Florida, Mississippi, North Carolina, Kentucky, South Carolina and Tennessee, as well as Louisiana east of the Mississippi River. Operations on the coasts of these states, except for Mobile Bay, are considered part of the Lower Seaboard Theater. Most other operations east of the Appalachian Mountains are part of the eastern theater. Operations west of the Mississippi River took place in the trans-Mississippi theater.
The eastern theater of the American Civil War consisted of the major military and naval operations in the states of Virginia, West Virginia, Maryland, and Pennsylvania, the District of Columbia, and the coastal fortifications and seaports of North Carolina.
The following engagements took place in the year 1864 during the American Civil War. The Union armies, under the command of U.S. Grant, launched multiple offenses in all theaters of the war, in an attempt to prevent Confederate forces from transferring troops from one army to another.
The Fight at Monterey Pass (or Gap) was an American Civil War military engagement beginning the evening of July 4, 1863, during the Retreat from Gettysburg. A Confederate wagon train of Lt. Gen. Richard S. Ewell's Second Corps, Army of Northern Virginia, withdrew after the Battle of Gettysburg, and Union cavalry under Brig. Gen. H. Judson Kilpatrick attacked the retreating Confederate column. After a lengthy delay in which a small detachment of Maryland cavalrymen delayed Kilpatrick's division, the Union cavalrymen captured numerous Confederate prisoners and destroyed hundreds of wagons.
The Chattanooga campaign was a series of maneuvers and battles in October and November 1863, during the American Civil War. Following the defeat of Maj. Gen. William S. 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 Confederate Army of Northern Virginia began its Retreat from Gettysburg on July 4, 1863. Following General Robert E. Lee's failure to defeat the Union Army at the Battle of Gettysburg, he ordered a retreat through Maryland and over the Potomac River to relative safety in Virginia. The Union Army of the Potomac, commanded by Maj. Gen. George G. Meade, was unable to maneuver quickly enough to launch a significant attack on the Confederates, who crossed the river on the night of July 13 into South Mountain through Cashtown in a wagon train that extended for 15–20 miles, enduring harsh weather, treacherous roads, and enemy cavalry raids. The bulk of Lee's infantry departed through Fairfield and through the Monterey Pass toward Hagerstown, Maryland. Reaching the Potomac, they found that rising waters and destroyed pontoon bridges prevented their immediate crossing. Erecting substantial defensive works, they awaited the arrival of the Union army, which had been pursuing over longer roads more to the south of Lee's route. Before Meade could perform adequate reconnaissance and attack the Confederate fortifications, Lee's army escaped across fords and a hastily rebuilt bridge.
Ulysses S. Grant was the most acclaimed Union general during the American Civil War and was twice elected president. Grant began his military career as a cadet at the United States Military Academy at West Point in 1839. After graduation he went on to serve with distinction as a lieutenant in the Mexican–American War. Grant was a keen observer of the war and learned battle strategies serving under Generals Zachary Taylor and Winfield Scott. After the war Grant served at various posts especially in the Pacific Northwest; he was forced to retire from the service in 1854 due to accusations of drunkenness. He was unable to make a success of farming and on the onset of the Civil War in April 1861, Grant was working as a clerk in his father's leather goods store in Galena, Illinois. When the war began his military experience was needed, and Congressman Elihu B. Washburne became his patron in political affairs and promotions in Illinois and nationwide.
The Battle of Fairfax Court House was fought during the Gettysburg Campaign of the American Civil War between two cavalry detachments from the Union Army of the Potomac, commanded by General Joseph Hooker, and the Confederate Army of Northern Virginia, commanded by General Robert E. Lee.
