Lee’s Headquarters at Gettysburg

History & Significance

In 2014, the Civil War Trust has an amazing opportunity to preserve the Mary Thompson House, which served during the Battle of Gettysburg as both the headquarters of Gen. Robert E. Lee and the site of some of the bloodiest scenes of the battle.

What is Lee’s Headquarters?  

Lee’s Headquarters, also known as the Mary Thompson House, is a one-and-a-half story stone house, situated on a 4.01-acre tract on the crest of Seminary Ridge, west of the town of Gettysburg on the north side of the Chambersburg Pike. During the Civil War the property was co-owned by Thaddeus Stevens, an influential and powerful Pennsylvania Congressman, and a 69-year-old widow named Mary Thompson. The still-extant James Henry Thompson House, owned by Mary’s son, is located on the south side of the road.

Why is it important?

On the afternoon of July 1, 1863, the Mary Thompson House and the land around it were caught in the maelstrom of a deadly and bloody struggle, as Confederate forces overran the final defensive positions of the Union 1st Corps west of Gettysburg. Union artillery and infantry occupied the section of Seminary Ridge on which the house still stands.  

Three guns of James Stewart’s Battery B, 4th United States Artillery (commanded by Lt. Davison), were positioned directly on the property in question, a point from which they delivered raking canister fire into the ranks of General Alfred Scales’s North Carolinians (a government marker honoring the battery stands near the site). Scales reported that his brigade “encountered a most terrific fire of grape and shell on our flank, and grape and musketry on our front. Every discharge made sad havoc in our line, but still we pressed on at a double-quick until we reached a distance of about 75 yards from the ridge, and about the same distance from the college [Seminary]… Our line had been broken up, and now only a squad here and there marked the place where regiments had rested.”

Part of Union Colonel Roy Stone’s 2nd Brigade (specifically the 143rd Pennsylvania, which had never previously been under fire) also occupied the ground we seek to save, until being driven back by North Carolinians under General Junius Daniel, following the collapse of the Union right on Oak Hill. Many Federal soldiers sought shelter in the Railroad Cut through Seminary Ridge, adjacent to the north side of the property. When the Southern forces surrounded the cut, many were taken prisoner, resulting in the largest mass capture of Union troops during the battle.

Just south of the Chambersburg Pike, the 149th and 150th Pennsylvania regiments connected to the right of the famed Iron Brigade, inflicting — according to Confederate Brigade commander General Abner Perrin — “the most destructive fire of musketry I have ever been exposed to.”  The North Carolinians advancing toward this property under Scales eventually could go no further.  Every field officer in his brigade, save one, fell killed or wounded.  

The 13th North Carolina, the regiment advancing closest to the Chambersburg Pike, lost 150 of 180 men. Stevens’s Union battery, operating from the land we are seeking to buy, expended 57 rounds of deadly canister within a few short minutes. A colonel of the 14th South Carolina noted, “To stop was destruction.  To retreat was disaster… not a foot of ground presented a place of safety.”

On the evening of July 1, Robert E. Lee arrived on the field and established his headquarters on the Thompson property. On this ground, over the next few days, he conferred with generals Longstreet, Ewell, Stuart and other officers to plan the direction of the battle. On the second and third days of fighting, Seminary Ridge was converted into a Southern defensive position and this property bristled with Confederate artillery.

The case can easily be made that the Lee’s Headquarters building is one of the most important unprotected historic homes in the entire United States.
