he Battle of Gettysburg, fought from July 1 to July 3, 1863, is considered the most important engagement of the American Civil War. After a great victory over Union forces at Chancellorsville, General Robert E. Lee marched his Army of Northern Virginia into Pennsylvania in late June 1863. On July 1, the advancing Confederates clashed with the Union’s Army of the Potomac, commanded by General George G. Meade, at the crossroads town of Gettysburg. The next day saw even heavier fighting, as the Confederates attacked the Federals on both left and right. On July 3, Lee ordered an attack by fewer than 15,000 troops on the enemy’s center at Cemetery Ridge. The assault, known as “Pickett’s Charge,” managed to pierce the Union lines but eventually failed at the cost of thousands of rebel casualties. Lee was forced to withdraw his battered army toward Virginia on July 4. The Union had won in a major turning point, stopping Lee’s invasion of the North. It inspired Lincoln’s “Gettysburg Address,” which became one of the most famous speeches of all time.
Battle of Gettysburg: Lee’s Invasion of the North
In May 1863, Robert E. Lee’s Confederate Army of Northern Virginia had scored a smashing victory over the Army of the Potomac at Chancellorsville. Brimming with confidence, Lee decided to go on the offensive and invade the North for a second time (the first invasion had ended at Antietam the previous fall). In addition to bringing the conflict out of Virginia and diverting northern troops from Vicksburg, where the Confederates were under siege, Lee hoped to gain recognition of the Confederacy by Britain and France and strengthen the cause of northern “Copperheads” who favored peace.
On the Union side, President Abraham Lincoln had lost confidence in the Army of the Potomac’s commander, Joseph Hooker, who seemed reluctant to confront Lee’s army after the defeat at Chancellorsville. On June 28, Lincoln named Major General George Gordon Meade to succeed Hooker. Meade immediately ordered the pursuit of Lee’s army of 75,000, which by then had crossed the Potomac River into Maryland and marched on into southern Pennsylvania.
Battle of Gettysburg Begins: July 1
Upon learning that the Army of the Potomac was on its way, Lee planned to assemble his army in the prosperous crossroads town of Gettysburg, 35 miles southwest of Harrisburg, Pennsylvania. One of the Confederate divisions in A.P. Hill’s command approached the town in search of supplies early on July 1, only to find that two Union cavalry brigades had arrived the previous day. As the bulk of both armies headed toward Gettysburg, Confederate forces (led by Hill and Richard Ewell) were able to drive the outnumbered Federal defenders back through town to Cemetery Hill, located a half mile to the south.
Seeking to press his advantage before more Union troops could arrive, Lee gave discretionary orders to attack Cemetery Hill to Ewell, who had taken command of the Army of Northern Virginia’s Second Corps after Lee’s most trusted general, Thomas J. “Stonewall” Jackson, was mortally wounded at Chancellorsville. Ewell declined to order the attack, considering the Federal position too strong; his reticence would earn him many unfavorable comparisons to the great Stonewall. By dusk, a Union corps under Winfield Scott Hancock had arrived and extended the defensive line along Cemetery Ridge to the hill known as Little Round Top. Three more Union corps arrived overnight to strengthen its defenses.
