During the Revolutionary War, George Washington made his headquarters at Hasbrouck House from April 1782 to August 1783, after the Continental Army's successful Yorktown campaign in Virginia had already changed the course of the war and made victory seem all but assured. On December 7, 1782, Rochambeau arrived there to meet with Washington one last time. In their previous meetings they had focused on war strategy, but now they were saying goodbye. One week earlier, the Americans and British had agreed to preliminary Articles of Peace, although the Revolutionary War did not formally end until May 1784, when both countries had ratified the 1783 Treaty of Paris. Nearby, the Continental Army's last encampment included Washington's headquarters in Newburgh, General Gates and his troops near New Windsor, and the New Windsor Cantonment, the 1782-1783 winter quarters of about 7,000 soldiers and 500 women and children living in nearly 600 log huts.
