George Meade took the small house just down from the slope of Cemetery Ridge as his headquarters. It had the advantage of being close to the center of his extended line and access to the road system being right on the Taneytown Road. It also had a view of the signal station on Little Round Top.
During the artillery barge on the third day, the confederates fired long and shelled the Leister Farm causing Meade to abandon his headquarters. After the battle, the farm was littered with dead horses. In the high heat, the farm like most of Gettysburg was invested with flies and the smell of rotting flesh. Not getting any help from the army, the Lydia Leister and her children burned the dead horses and sold the bone/ash mix as fertilizer.
