In the Battle of Gettysburg, Union Major General George Meade's Army of the Potomac defeated attacks by Confederate General Robert E. Lee's Army of Northern Virginia, halting Lee's invasion of the North and forcing his retreat.[fn 1][16]
After his success at Chancellorsville in Virginia in May 1863, Lee led his Confederate forces through Shenandoah Valley to begin the Gettysburg Campaign, his second attempted invasion of the North. With Lee's army in high spirits, he intended to shift the focus of the summer campaign from war-ravaged Northern Virginia in the hopes of penetrating as far as Harrisburg, Pennsylvania or Philadelphia, which he hoped would convince northern politicians to abandon their prosecution of the war. President Abraham Lincoln initially prodded Major General Joseph Hooker to move his Union forces in pursuit of Lee, but relieved Hooker of his command just three days before the battle, replacing him with Meade.
On July 1, 1863, as Lee's forces moved on Gettysburg in the hopes of destroying the Union Army, the two armies initially collided, and the battle commenced. Low ridges to the northwest of Gettysburg were initially defended by a Union cavalry division under Brigadier General John Buford, and soon reinforced with two corps of Union infantry. Two large Confederate corps assaulted them from the northwest and north, however, collapsing the hastily developed Union lines, leading them to retreat through the streets of Gettysburg to the hills just south of the city.[17] On the second day of battle, on July 2, the Union line was laid out in a defensive formation resembling a fishhook. In the late afternoon, Lee launched a heavy assault on the Union's left flank, leading to fierce fighting at Little Round Top, the Wheatfield, Devil's Den, and the Peach Orchard. On the Union's right flank, Confederate demonstrations escalated into full-scale assaults on Culp's Hill and Cemetery Hill. Despite incurring significant losses, Union forces held their lines.
On the third day of battle, July 3, fighting resumed on Culp's Hill, and cavalry battles raged to the east and south of Gettysburg, but the main military engagement was a dramatic Confederate infantry assault of approximately 12,000 Confederates troops, who attacked the center of the Union line at Cemetery Ridge in what is known as Pickett's Charge. The Confederate charge was repelled by Union rifle and artillery fire, leading to great Confederate losses. The following day, on the Fourth of July, Lee led his Confederate troops on the torturous retreat from the North. Between 46,000 and 51,000 soldiers from both armies were casualties in the three-day battle, representing the most deadly battle in U.S. history.
On November 19, President Lincoln traveled to Gettysburg, where he spoke at a ceremony dedicating Gettysburg National Cemetery that honored the fallen Union soldiers and redefined the purpose of the Civil War in his famed Gettysburg Address, a 271-word address considered one of the famous speeches in American history.[18][19]
Thus, on June 3, Lee's army began to shift northward from Fredericksburg, Virginia. Following the death of Thomas J. "Stonewall" Jackson, Lee reorganized his two large corps into three new corps, commanded by Lieutenant General James Longstreet (First Corps), Lieutenant General Richard S. Ewell (Second), and Lieutenant General A.P. Hill (Third); both Ewell and Hill, who had formerly reported to Jackson as division commanders, were new to this level of responsibility. The cavalry division remained under the command of Major General J.E.B. Stuart.[21]
The first major action of the campaign took place on June 9 between cavalry forces at Brandy Station, near Culpeper, Virginia. The 9,500 Confederate cavalrymen under Stuart were surprised by Major General Alfred Pleasonton's combined arms force of two cavalry divisions (8,000 troopers) and 3,000 infantry, but Stuart eventually repelled the Union attack. The inconclusive battle, the largest predominantly cavalry engagement of the war, proved for the first time that the Union horse soldier was equal to his Southern counterpart.[22]
By mid-June, the Army of Northern Virginia was poised to cross the Potomac River and enter Maryland. After defeating the Union garrisons at Winchester and Martinsburg, Ewell's Second Corps began crossing the river on June 15. Hill's and Longstreet's corps followed on June 24 and 25. Hooker's army pursued, keeping between Washington, D.C., and Lee's army. The Union army crossed the Potomac from June 25 to 27.[23]
Lee gave strict orders for his army to minimize any negative effects on the civilian population.[24][25] Food, horses, and other supplies were generally not seized outright unless a citizen concealed property, although quartermasters reimbursing Northern farmers and merchants with Confederate money which was virtually worthless or with equally worthless promissory notes were not well received.[26] Various towns, most notably York, Pennsylvania, were required to pay indemnities in lieu of supplies, under threat of destruction.[27] During the invasion, the Confederates seized between 40 and nearly 60 northern African Americans. A few of them were escaped fugitive slaves, but many were freemen; all were sent south into slavery under guard.[12][13]
On June 26, elements of Major General Jubal Early's division of Ewell's corps occupied the town of Gettysburg after chasing off newly raised 26th Pennsylvania emergency militia in a series of minor skirmishes.[28] Early laid the borough under tribute, but did not collect any significant supplies. Soldiers burned several railroad cars and a covered bridge, and destroyed nearby rails and telegraph lines. The following morning, Early departed for adjacent York County.[29]
Meanwhile, in a controversial move, Lee allowed Stuart to take a portion of the army's cavalry and ride around the east flank of the Union army. Lee's orders gave Stuart much latitude, and both generals share the blame for the long absence of Stuart's cavalry, as well as for the failure to assign a more active role to the cavalry left with the army. Stuart and his three best brigades were absent from the army during the crucial phase of the approach to Gettysburg and the first two days of battle. By June 29, Lee's army was strung out in an arc from Chambersburg (28 mi (45 km) northwest of Gettysburg) to Carlisle (30 mi (48 km) north of Gettysburg) to near Harrisburg and Wrightsville on the Susquehanna River.[30]
In a dispute over the use of the forces defending the Harpers Ferry garrison, Hooker offered his resignation, and Abraham Lincoln and General-in-Chief Henry W. Halleck, who were looking for an excuse to rid themselves of him, immediately accepted. They replaced Hooker early on the morning of June 28 with Major General George Gordon Meade, then commander of the V Corps.[31]
When Pettigrew's troops approached Gettysburg on June 30, they noticed Union cavalry under Major General John Buford arriving south of town, and Pettigrew returned to Cashtown without engaging them. When Pettigrew told Hill and Heth what he had seen, neither general believed that there was a substantial Union force in or near the town, suspecting that it had been only Pennsylvania militia. Despite Lee's order to avoid a general engagement until his entire army was concentrated, Hill decided to mount a significant reconnaissance in force the following morning to determine the size and strength of the enemy force in his front. Around 5 a.m. on Wednesday, July 1, two brigades of Heth's division advanced to Gettysburg.[34]
During the advance on Gettysburg, Reynolds was in operational command of the left, or advanced, wing of the Army, consisting of the I, III, and XI corps.[36] Many other Union units (not part of the Army of the Potomac) were actively involved in the Gettysburg Campaign, but not directly involved in the Battle of Gettysburg. These included portions of the Union IV Corps, the militia and state troops of the Department of the Susquehanna, and various garrisons, including that at Harpers Ferry.
Anticipating that the Confederates would march on Gettysburg from the west on the morning of July 1, Buford laid out his defenses on three ridges west of the town: Herr Ridge, McPherson Ridge and Seminary Ridge. These were appropriate terrain for a delaying action by his small cavalry division against superior Confederate infantry forces, meant to buy time awaiting the arrival of Union infantrymen who could occupy the strong defensive positions south of town at Cemetery Hill, Cemetery Ridge, and Culp's Hill. Buford understood that if the Confederates could gain control of these heights, Meade's army would have difficulty dislodging them.[38]
Heth's division advanced with two brigades forward, commanded by brigadier generals James J. Archer and Joseph R. Davis. They proceeded easterly in columns along the Chambersburg Pike. Three mi (5 km) west of town, about 7:30 a.m. on July 1, the two brigades met light resistance from vedettes of Union cavalry, and deployed into line. According to lore, the Union soldier to fire the first shot of the battle was Lieutenant Marcellus Jones.[39] Eventually Heth's men encountered dismounted troopers of Colonel William Gamble's cavalry brigade. The dismounted troopers resisted stoutly, delaying the Confederate advance with most firing their breech-loading Sharp's carbines from behind fences and trees. (A small number of troopers had other carbine models. A small minority of historians have written that some troopers had Spencer repeating carbines or Spencer repeating rifles but most sources disagree.)[40][fn 2] Still, by 10:20 a.m., the Confederates had pushed the Union cavalrymen east to McPherson Ridge, when the vanguard of the I Corps (Major General John F. Reynolds) finally arrived.[41]
North of the pike, Davis gained a temporary success against Brigadier General Lysander Cutler's brigade but was repelled with heavy losses in an action around an unfinished railroad bed cut in the ridge. South of the pike, Archer's brigade assaulted through Herbst (also known as McPherson's) Woods. The Union Iron Brigade under Brigadier General Solomon Meredith enjoyed initial success against Archer, capturing several hundred men, including Archer himself.[42]
