Morristown, the Revolution's Harshest Winter
« It takes a great soul to endure a great destiny. »— George Washington, 1778
The Revolutionary Winters in Morristown
Morristown, New Jersey, played a crucial role during the American Revolutionary War by serving as the winter headquarters for George Washington's Continental Army twice. The first stay occurred from January to May 1777, following the strategic victories at Trenton and Princeton. Washington and his staff resided at Judge Jacob Ford Jr.'s house, leveraging the town's defensive position.
The second and longer winter, from December 1779 to June 1780, was one of the harshest ever recorded. Dubbed the “Hard Winter,” it saw the army grapple with incessant blizzards, freezing temperatures, and severe shortages of food and clothing. The disastrous conditions tested the troops' resilience and Washington's determination, who maintained his army's cohesion despite mutinies and plots, making Morristown a symbol of American perseverance in the face of adversity.
