Here he ended the Newburgh Conspiracy, an apparent planned military coup by the Continental Army in March 1783, ensuring that civilians would run the American government. Subsequently, Washington drafted three memorable documents in which he reaffirmed the fundamental principle of subordination of the military to civilian control and helped lay the foundation for the Nation's orderly transition from war to peace.

This fairly small farmhouse provided both living and working space for Washington and his wife, officers, servants and enslaved individuals, along with a steady stream of guests.
