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.
Retreat from Gettysburg
Although many descriptions of the Gettysburg Campaign end with Lee's crossing of the Potomac on July 13–14, the two armies did not take up positions across from each other on the Rappahannock River for almost two weeks and the official reports of the armies include the maneuvering and minor clashes along the way. On July 16 the cavalry brigades of Fitzhugh Lee and Chambliss held the fords on the Potomac at Shepherdstown to prevent crossing by the Federal infantry. The cavalry division under David Gregg approached the fords and the Confederates attacked them, but the Union cavalrymen held their position until dark before withdrawing. Meade called this a "spirited contest."
