Iron Plaque

At Morristown, Washington was close to the northern New Jersey iron furnaces of Hibernia, Pompton, Mount Hope and Ringwood. Cannon balls and shells from these furnaces were on frequent order for the Continental Army during much of the Revolution. Firebacks, kitchen implements and iron bars or "pigs" were also produced at these casting works.<br><br> During the war, two great chains of large iron links were placed across the Hudson River as an obstruction to British warships. The first was made at nearby Ringwood Furnace and placed at Fort Montgomery. It was replaced by an even larger chain at West Point with links each measuring about 10 by 30 inches.
