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.
David McMurtrie Gregg
In the middle of the Gettysburg Campaign, Pleasonton reorganized his corps and Gregg now commanded the 2nd Division. He led it in cavalry engagements at Aldie, Middleburg, and Upperville. While his fellow, newly promoted division commander Brig. Gen. John Buford was initiating the Battle of Gettysburg on July 1, 1863, Gregg was still moving north. His division arrived mid-day on July 2 and took up positions to protect the right flank and rear of the Union Army. On July 3, Three miles east of Gettysburg, in what is now called "East Cavalry Field", Stuart's forces collided with Gregg's division and Brig. Gen. George A. Custer's brigade of the 3rd Division. A lengthy mounted battle, including hand-to-hand combat, ensued. Both sides claimed victory. After the battle Gregg took his division to Chambersburg Pa, and did not participate in the Cavalry pursuit of the Army of Northern Va.
