The farmhouse of Lydia Leister is on Taneytown Road at the intersection with Hunt Avenue. Its central location close behind the Union lines made it a perfect location as headquarters for the Army of the Potomac.
James Leister had died in 1859, leaving behind Lydia and six children. Lydia bought the small, wooden two-room house in 1861. It had a small hayfield and several apple and peach trees, as well as a spring. Lydia's sister, Catherine, had married John Slyder, whose farm near Big Round Top also played an important role in the battle.
Lydia left the farm as the battle grew near. Its position on the reverse slope of Cemetery Ridge just inside the fishook curve of the Union lines made it a perfect location for the nerve center of the Union Army. Meade's famous council of war on the evening of July 2nd took place in the house's miniscule main room.
This nerve center was disrupted during the artillery bombardment preceding Pickett's Charge. The farm's location immediately behind the central point of the attack resulted in its being deluged with numerous overshoots from the hour-long Confederate barrage. One burst among the staff horses in the yard, while others carried away the steps and porch supports. Flying splinters dictated a move outside.
When Meade saw some members of the staff favoring the downrange side of the flimsy house, the fearless, twice-wounded Meade joked with them about their imaginary shelter. But for the sake of efficiency he eventually moved his shot-torn staff a few hundred yards away to a nearby barn. When it, too, proved to be a target, they moved on to the 12th Army Corps Headquarters on Powers Hill, which was part of the Union Army's series of signal stations.
Lydia Leister returned home to find her home punctured by numerous shot holes and seventeen dead horses in her yard, several of which had been burned around her best peach tree. Her other fruit trees were destroyed, two tons of hay was gone from the barn, her wheat had been trampled, her spring spoiled, and all her fences burned.
In 1865 she told a reporter that all she received in compensation for the damage was the proceeds from the sale of the bones of the dead horses, at fifty cents per hundred pounds.
The house today belongs to the National Park Service and you can peer inside the window of the tiny room where one of the most important councils of war in American history occured.
