Washington Establishes Headquarters at Hasbrouck House
April 1, 1782
Washington established his headquarters at Hasbrouck House in Newburgh in April 1782, as the army settled into the long wait for peace negotiations. The strategic position on the Hudson bluff gave visibility over the river and proximity to the New Windsor cantonment. He would remain for sixteen months — the longest continuous stay at any single headquarters of the war.
