Major John Clark's House (structure no longer standing)
Backstory and Context
Today the York County Human Services Center stands over a historical location, the southwest corner of Beaver and Market Street. In 1912, this site was home to the Bon Ton's original flagship store and before then it was the location of the home of Spymaster Major John Clark. The Major is perhaps best known for the spy network he operated in Philadelphia for George Washington during the Revolutionary War. Clark had his network firmly in place when Philadelphia fell to the British in September of 1777, after the Battle of Brandywine. From within Philadelphia, Clark's network was able to provide intelligence about British strategies and troop movements, as well pass on false information to the British.
“He is active, sensible and enterprising and has rendered me very great assistance since the army has been in Pennsylvania by procuring me constant and certain intelligence of the motion and intentions of the Enemy.”
