Devil's Den

Rose Woods is a Gettysburg Battlefield forested area that is an American Civil War site of the battle's Hood's Assault, McLaws' Assault, and McCandless' Advance. "Scene of the first line of Union defenses" on the Battle of Gettysburg, Second Day; the 1st Texas Infantry and 3rd Arkansas Infantry Regiments attacked Ward's 2nd Brigade line in the woods. The last combat on the Battle of Gettysburg, Third Day, was "in the early evening. Colonel William McCandless's brigade of Pennsylvania Reserves advanced across the Wheatfield into Rose's Woods where they managed to inflict heavy losses on the 15th Georgia" which had failed to retreat to Warfield Ridge after Longstreet's Assault. Two days later Timothy H. O'Sullivan photographed corpses moved for burial to the edge of Rose Woods and which were subsequently reinterred in cemeteries. De Trobriand Avenue and other Military Park roads provide access to the woods' battlefield monuments, and the woods' railbed for the 1894-1916 Gettysburg Electric Railway is a historic district contributing structure that is now a rail trail. Monuments in the woods include the 1890 Sixty-fourth New York Regiment Monument, and Wheat-field Park in "Wible's Grove" was a commemorative era trolley park. The trolley's overhead power line broke at Wible's Woods in 1900, and the woods had the postbellum "William Wible's Quarry" for Gettysburg Granite (cf. Rosensteel's Quarry north of the Round Top Museum). In 2004, the archeological remains of the former trolley bridge in Rose Woods were named a historic district contributing structure.

The Round Top hospitals during the Battle of Gettysburg were located at the Little Round Top side of the Gettysburg Battlefield at 2 houses now in the community of Round Top, Pennsylvania.

Little Round Top is the smaller of two rocky hills south of Gettysburg, Pennsylvania—the companion to the adjacent, taller hill named Big Round Top. It was the site of an unsuccessful assault by Confederate troops against the Union left flank on July 2, 1863, the second day of the Battle of Gettysburg, during the American Civil War. Little Round Top was successfully defended by a brigade under Colonel Strong Vincent, who was mortally wounded during the fighting and died five days later. The 20th Maine Volunteer Infantry Regiment, commanded by Colonel Joshua Lawrence Chamberlain, fought its most famous engagement there, culminating in a dramatic downhill bayonet charge. The battle at Little Round Top subsequently became one of the most well-known actions at Gettysburg, and of the entire war.

Big Round Top is a boulder-strewn hill notable as the topographic high point: 3  of the Gettysburg Battlefield and for 1863 American Civil War engagements for which Medals of Honor were awarded. In addition to battle monuments, a historic postbellum structure on the uninhabited hill is the Big Round Top Observation Tower Foundation Ruin.

Round Top is a populated place in the U.S. state of Pennsylvania, near Little Round Top. It is notable for two Battle of Gettysburg hospitals, the 1884 Round Top Station, and several battlefield commemorative era attractions such as Round Top Park and the Round Top Museum. The unincorporated community lies on an elevated area of the north-south Taneytown Road with 3 intersections at Blacksmith Shop Road to the northeast, Wheatfield Road (west from "Roundtop"), and Sachs Road (east from "Sedgwick").

Round Top Station was the southernmost station of the Gettysburg and Harrisburg Railroad and was located west of a blacksmith shop along the Taneytown Road that was in operation in 1880.

The Alabama State Monument, also known as the Alabama State Memorial, is a monument which is located in the Gettysburg National Military Park. It memorializes the Confederate units from Alabama that took part in the Battle of Gettysburg.

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.

Pitzer Woods is a Gettysburg Battlefield site used for Gettysburg Battlefield camps after the American Civil War such as the 1933–37 Camp Renaissance Civilian Conservation Corps camp.
