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.
Alpheus S. Williams
In the Battle of Gettysburg, Williams' division arrived on the battlefield late in the afternoon of July 1, 1863, and occupied Benner's Hill, east of the town of Gettysburg. On July 2, the XII Corps took up positions on Culp's Hill, the right flank of the Union line. At this point, due to a command misunderstanding, Henry Slocum believed that he was in command of the "Right Wing" of the army, consisting of the XI and XII Corps. Therefore, Williams assumed temporary command of the XII Corps and controlled it for the rest of the battle. Brig. Gen. Thomas Ruger took command of Williams' division.
