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.
Winfield Scott Hancock
Hancock's most famous service was as a new corps commander at the Battle of Gettysburg, July 1 to 3, 1863. After his friend, Maj. Gen. John F. Reynolds, was killed early on July 1, Maj. Gen. George G. Meade, the new commander of the Army of the Potomac, sent Hancock ahead to take command of the units on the field and assess the situation. Hancock thus was in temporary command of the "left wing" of the army, consisting of the I, II, III, and XI Corps. This demonstrated Meade's high confidence in him, because Hancock was not the most senior Union officer at Gettysburg at the time. Hancock and the more senior XI Corps commander, Maj. Gen. Oliver O. Howard, argued briefly about this command arrangement, but Hancock prevailed and he organized the Union defenses on Cemetery Hill as more numerous Confederate forces drove the I and XI Corps back through the town. He had the authority from Meade to withdraw the forces, so he was responsible for the decision to stand and fight at Gettysburg. At the conclusion of the day's action, Maj. Gen. Henry Warner Slocum arrived on the field and assumed command until Gen. Meade arrived after midnight.
