Gettysburg National Military Park
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, & 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.
Daniel Sickles
The Battle of Gettysburg was the occasion of the most famous incident and the effective end of Sickles' military career. On July 2, 1863, Army of the Potomac commander Maj. Gen. George G. Meade ordered Sickles' corps to take up defensive positions on the southern end of Cemetery Ridge, anchored in the north to the II Corps and to the south, the hill known as Little Round Top. Sickles was unhappy to see the "Peach Orchard," a slightly higher terrain feature, to his front. He violated orders by marching his corps almost a mile in front of Cemetery Ridge. This had two effects: it greatly diluted the concentrated defensive posture of his corps by stretching it too thin, and it created a salient that could be bombarded and attacked from multiple sides. About this time (3 p.m.), Meade called a meeting of his corps commanders. Sickles did not appear. An aide to Brig. Gen. Gouverneur K. Warren soon reported the situation. Meade and Warren rode to Sickles' position, where Meade demanded an explanation from the general. Meade refused Sickles' offer to withdraw because he realized it was too late and the Confederates would soon attack, putting a retreating force in even greater peril.
