Gettysburg, Battle of

(July 1–3, 1863) Major engagement in the American Civil War at Gettysburg, Pa.

, regarded as the war's turning point. After defeating Union forces at the Battle of Chancellorsville, Robert E. Lee decided to invade the North with 75,000 troops. When he learned that the Union's Army of the Potomac had a new commander, George Meade, he led his own troops to Gettysburg, a strategic crossroads. On the first day of battle, Meade's advance force under John Buford held the site until reinforcements arrived. On the second day, the Confederates attacked Union lines at Little Round Top, Cemetery Hill, Devil's Den, the Wheatfield, and the Peach Orchard. On the third day, Lee sent 15,000 troops to assault Cemetery Ridge, held by 10,000 Union troops under Winfield S Hancock. A Confederate spearhead broke through the Union artillery defense but was stopped by a fierce Union counterattack on three sides. At night under cover of a heavy rain on July 4, Lee led his troops back to Virginia; Meade was later criticized for not pursuing him. Losses totaled about 23,000 casualties among 88,000 Union troops and over 20,000 casualties among 75,000 Confederates.

▪ American Civil War [1863]

 (July 1–3, 1863), major engagement in the American Civil War fought 35 miles (56 km) southwest of Harrisburg, Pennsylvania, that was a crushing Southern defeat. After defeating the Union forces of General Joseph Hooker (Hooker, Joseph) at Chancellorsville, Virginia, in May, Confederate General Robert E. Lee (Lee, Robert E.) decided to invade the North in hopes of further discouraging the enemy and possibly inducing European countries to recognize the Confederacy. His invasion army numbered 75,000 troops. When he learned that the Union Army of the Potomac had a new commander, General George G. Meade (Meade, George G), Lee ordered General R.S. Ewell to move to Cashtown or Gettysburg. However, the commander of Meade's advance cavalry, General John Buford, recognized the strategic importance of Gettysburg as a road centre and was prepared to hold this site until reinforcements arrived.

 The first day of battle saw considerable fighting in the area, Union use of newly issued Spencer repeating carbines, heavy casualties on each side, and the simultaneous conclusion by both commanders that Gettysburg was the place to fight. On the second day there were a great number of desperate attacks and counterattacks in an attempt to gain control of such locations as Little Round Top (see photograph—>), Cemetery Hill, Devil's Den, the Wheatfield, and the Peach Orchard. There were again heavy losses on both sides. On the third day Lee was determined to attack. Some 15,000 Confederate troops assaulted Cemetery Ridge, held by about 10,000 Federal infantrymen. The Southern spearhead broke through and penetrated the ridge, but there it could do no more. Critically weakened by artillery during their approach, formations hopelessly tangled, lacking reinforcement, and under savage attack from three sides, the Southerners retreated, leaving 19 battle flags and hundreds of prisoners. On July 4 Lee waited to meet an attack that never came. That night, taking advantage of a heavy rain, he started retreating toward Virginia. His defeat stemmed from overconfidence in his troops, Ewell's inability to fill the boots of General Thomas J. “Stonewall” Jackson (Jackson, Thomas Jonathan), and faulty reconnaissance. Though Meade has been criticized for not destroying the enemy by a vigorous pursuit, he had stopped the Confederate invasion and won a critical three-day battle.

 Losses were among the war's heaviest: of 88,000 Northern troops, casualties numbered about 23,000; out of 75,000 Southerners, more than 20,000. Dedication of the National Cemetery at the site in November 1863 was the occasion of President Abraham Lincoln's Gettysburg Address. The battlefield became a national military park in 1895, and jurisdiction passed to the National Park Service in 1933.
