Est. 1772 · Field hospital for both sides at the Battle of Princeton (January 3, 1777) · Brigadier General Hugh Mercer died here January 12, 1777 · Part of Princeton Battlefield State Park — significant Revolutionary War site · National Register of Historic Places
The Thomas Clarke House was built in 1772 by the Clarke family, Quaker farmers who worked the land at what is now the edge of Princeton Battlefield State Park. On the morning of January 3, 1777, Washington's Continental Army engaged British forces at the Battle of Princeton — one of the key engagements in the New Jersey campaign that reversed the dismal tide of the preceding months.
Brigadier General Hugh Mercer, commanding the advance column of the Continental Army, was thrown from his horse when it was shot during the fighting. Surrounded by British soldiers who reportedly mistook him for Washington, he refused to surrender. He was bayoneted multiple times. Soldiers carried him to the Clarke House, which was pressed into service as a field hospital for casualties on both sides.
Mercer died in the Clarke House on January 12, 1777, nine days after the battle. He was 51 years old. A trained physician who had served in the Battle of Culloden in Scotland in 1745 before emigrating to America, Mercer was one of the more experienced military officers in Washington's army. His death at the Clarke House was well-documented by contemporary accounts.
The house is preserved in its late 18th-century configuration and is managed as a museum within Princeton Battlefield State Park, which is administered by the New Jersey State Park Service. The American Battlefield Trust documents the site as a significant Revolutionary War heritage location.

Choking or tightening sensation in the upstairs bedroomDifficulty breathing reported by visitors to Mercer's death roomSounds and shadows on the battlefield grounds after dark
The paranormal account most consistently attached to the Clarke House is specific to a single room: the upstairs bedroom where Hugh Mercer was nursed through the nine days between the battle and his death. Visitors and custodians over the years have described an unexpected sensation of tightening around the throat or difficulty breathing when entering the room — sometimes attributed in local accounts to the fact that Mercer's cravat was removed during medical treatment of his bayonet wounds.
The choking account has no recorded investigative documentation — no EVP captures, no instrument readings in the published record. What it has is duration: the story appears in Princeton Magazine's compilation of the city's most persistent haunting accounts and has been repeated by multiple generations of guides and visitors who approached the room with no prior knowledge of the claim.
The battlefield itself has a separate paranormal dimension. Some visitors to the grounds after dark report sounds or shadows in the areas where the fighting was concentrated, consistent with battlefield hauntings documented at other Revolutionary War sites. These accounts are less specific than the Clarke House bedroom claim.
