High Water Mark of the Rebellion Monument

The high-water mark of the Confederacy or high tide of the Confederacy refers to an area on Cemetery Ridge near Gettysburg, Pennsylvania, marking the farthest point reached by Confederate forces during Pickett's Charge on July 3, 1863. Similar to a high water mark of water, the term is a reference to arguably the Confederate Army's best chance of achieving victory in the war. The line of advance was east of "The Angle" stone wall.

The Gettysburg Battlefield is the area of the July 1–3, 1863, military engagements of the Battle of Gettysburg within and around the borough of Gettysburg, Pennsylvania. Locations of military engagements extend from the 4-acre (1.6 ha) site of the first shot at Knoxlyn Ridge on the west of the borough, to East Cavalry Field on the east. A military engagement prior to the battle was conducted at the Gettysburg Railroad trestle over Rock Creek, which was burned on June 27.

The 72nd Pennsylvania Infantry Monument is an 1891 statuary memorial on the Gettysburg Battlefield. It is located on Cemetery Ridge, by The Angle and the copse of trees, where Union forces – including the 72nd Pennsylvania Infantry – beat back Confederate forces engaged in Pickett's Charge. The monument was the subject of a Pennsylvania Supreme Court case over control of the battlefield. It is depicted on the 2011 "Gettysburg" America the Beautiful quarter commemorative coin. The regiment erected an earlier monument in 1883. To avoid confusion, that is now usually referred to as the "Philadelphia Brigade" Monument.

Pickett's Charge (July 3, 1863), also known as the Pickett–Pettigrew–Trimble Charge, was an infantry assault ordered by Confederate General Robert E. Lee against Major General George G. Meade's Union positions on the last day of the Battle of Gettysburg in the commonwealth of Pennsylvania during the Civil War. Confederate troops made a frontal assault towards the center of Union lines, ultimately being repulsed with heavy casualties. Suffering from a lack of preparation and problems from the onset, the attack was a costly mistake that decisively ended Lee's invasion of the north and forced a retreat back to Virginia.The charge is popularly named after Major General George Pickett, one of three Confederate generals (all under the command of Lieutenant General James Longstreet) who led the assault. Pickett's Charge was part of Lee's "general plan" to take Cemetery Hill and the network of roads it commanded. His military secretary, Armistead Lindsay Long, described Lee's thinking: There was ... a weak point ... where [Cemetery Ridge], sloping westward, formed the depression through which the Emmitsburg road passes. Perceiving that by forcing the Federal lines at that point and turning toward Cemetery Hill [Hays' Division] would be taken in flank and the remainder would be neutralized. ... Lee determined to attack at that point, and the execution was assigned to Longstreet. Lee believed that, after Confederate attacks on both the left and right flanks of the Union lines on July 2, Meade would concentrate his defenses there to the detriment of his center. However, on the night of July 2, Meade correctly predicted to General Gibbon, after a council of war, that Lee would attack the center of his lines the following morning and reinforced that area with additional soldiers and artillery. The infantry assault was preceded by a massive artillery bombardment that was meant to soften up the Union defense and silence its artillery, but it was largely ineffective. Approximately 12,500 men in nine infantry brigades advanced over open fields for three-quarters of a mile (1200 m) under heavy Union artillery and rifle fire. Although some Confederates were able to breach the low stone wall that shielded many of the Union defenders, they could not maintain their hold and were repelled with over 50 percent casualties. Often cited as one of the turning points of the war, the farthest point reached by the attack has been referred to as the high-water mark of the Confederacy.

The Angle (Bloody Angle colloq.) is a Gettysburg Battlefield area which includes the 1863 Copse of Trees used as the target landmark for Pickett's Charge, the 1892 monument that marks the high-water mark of the Confederacy, a rock wall, and several other Battle of Gettysburg monuments.

The Brian Farm is an American Civil War area of the Gettysburg Battlefield used during the Pickett's Charge. On January 23, 2004, the farm's buildings, Boundary Stone Wall, and ID tablet were designated historic district contributing structures after the tract was used for the 1918 Camp Colt and other postbellum camps.

The Gettysburg National Military Park protects and interprets the landscape of the 1863 Battle of Gettysburg during the American Civil War. Located in Gettysburg, Pennsylvania, the park is managed by the National Park Service. The GNMP properties include most of the Gettysburg Battlefield, many of the battle's support areas during the battle (e.g., reserve, supply, and hospital locations), and several other non-battle areas associated with the battle's "aftermath and commemoration," including the Gettysburg National Cemetery. Many of the park's 43,000 American Civil War artifacts are displayed in the Gettysburg Museum and Visitor Center.The park has more wooded land than in 1863, and the National Park Service has an ongoing program to restore portions of the battlefield to their historical non-wooded conditions, as well as to replant historic orchards and woodlots that are now missing. In addition, the NPS is restoring native plants to meadows and edges of roads, to encourage habitat as well as provide for historic landscape. There are also considerably more roads and facilities for the benefit of tourists visiting the battlefield park. Attendance in 2018 was 950,000, a decline of 86% since 1970. The five major Civil War battlefield parks operated by the National Park Service (Gettysburg, Antietam, Shiloh, Chickamauga/Chattanooga and Vicksburg) had a combined 3.1 million visitors in 2018, down 70% from 10.2 million in 1970.The park was added to the National Register of Historic Places on October 15, 1966.

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 (from June 28) by Maj. Gen. George G. Meade. After his victory in the Battle of Chancellorsville, Lee's Army of Northern Virginia moved north for a massive raid designed to obtain desperately needed supplies, to undermine civilian morale in the North, and to encourage anti-war elements. Lee's army slipped away from Federal contact at Fredericksburg, Virginia, on June 3, 1863. The largest predominantly cavalry battle of the war was fought at Brandy Station on June 9. The Confederates crossed the Blue Ridge Mountains and moved north through the Shenandoah Valley, capturing the Union garrison at Winchester, in the Second Battle of Winchester, June 13–15. Crossing the Potomac River, Lee's Second Corps advanced through Maryland and Pennsylvania, reaching the Susquehanna River and threatening the state capital of Harrisburg. However, the Army of the Potomac was in pursuit and had reached Frederick, Maryland, before Lee realized his opponent had crossed the Potomac. Lee moved swiftly to concentrate his army around the crossroads town of Gettysburg. The Battle of Gettysburg was the deadliest of the war. Starting as a chance meeting engagement on July 1, the Confederates were initially successful in driving Union cavalry and two infantry corps from their defensive positions, through the town, and onto Cemetery Hill. On July 2, with most of both armies now present, Lee launched fierce assaults on both flanks of the Union defensive line, which were repulsed with heavy losses on both sides. On July 3, Lee focused his attention on the Union center. The defeat of his massive infantry assault, Pickett's Charge, caused Lee to order a retreat that began the evening of July 4. The Confederate retreat to Virginia was plagued by bad weather, difficult roads, and numerous skirmishes with Union cavalry. However, Meade's army did not maneuver aggressively enough to prevent Lee from crossing the Potomac to safety on the night of July 13–14.
