Context: The Battle of Gettysburg ( , with an sound) was fought July 1–3, 1863, in and around the town of Gettysburg, Pennsylvania, by Union and Confederate forces during the American Civil War.  The battle involved the largest number of casualties of the entire war and is often described as the war's turning point.  Union Maj. Gen. George Meade's Army of the Potomac defeated attacks by Confederate Gen. Robert E. Lee's Army of Northern Virginia, halting Lee's invasion of the North. The Battlefield Airport was the Gettysburg Battlefield site of the Battlefield Airways, Inc. west of the Peach Orchard between the Emmitsburg road and Warfield Ridge.  The corporation and airfield were operated in the 1920s by Herbert J. Fahy, an aeronautical record holder and former Air Service pilot who subsequently was a Lockheed test pilot.  His wife, Clair May Fahy, also operated from the airfield  and flew a Travel Air with Curtiss OX-5 in the 1929 Women's Air Derby.  The airport was denied a 1928 state Public Service Commission charter to fly sightseers over the battlefield because it would compete with the Gettysburg Flying Service, where a new airport was built in 1942  and re-established in 1969. Camp Harding was a 1922 United States Marine Corps encampment on the Gettysburg Battlefield for the Marine Expeditionary Force which conducted maneuvers and a reenactment of Pickett's Charge.  The camp was on the east slope of Seminary Ridge and used the area between the Emmitsburg Road and West Confederate Avenue (a large open air theater was at the Virginia Monument). The Peach Orchard is a Gettysburg Battlefield site at the southeast corner of the north-south Emmitsburg Road intersection with the Wheatfield Road.  The orchard is demarcated on the east and south by Birney Avenue, which provides access to various memorials regarding the "momentous attacks and counterattacks in…the orchard on the afternoon of July 2, 1863." Frank Emmanuel Tolbert (February 3, 1910 – April 22, 1980) was a Liberian politician and brother of President William R. Tolbert, Jr. The oldest son of William R. Tolbert Sr., national chairman of the ruling True Whig Party, he grew up in Bensonville, attended Zion Praise Baptist Church, graduated from Liberia College, and became involved in politics relatively early in life.  As his family became more and more closely connected to the family of Supreme Court Justice William V.S. Tubman, Frank began to become prominent: when Tubman ran for President in 1943, he was rumoured to be Tubman's first choice for Vice President, although his younger brother William was eventually chosen, perhaps because of Frank's unpredictable moods and violent temper.
