This Day in History: April 30

Midway through the War of Independence, on April 30, 1778, the American Revolutionaries succeeded in stringing a massive floating chain across the Hudson River at West Point, N.Y. Quickly dubbed "General Washington's Watch Chain" by the Continental soldiers, the unusual obstruction denied use of this strategic waterway to the British for the remainder of the war. The chain's 800 wrought iron links, supported by a connecting forty huge log rafts, were hastily forges at nearby Sterling Furnace in the Ramapo Mountains. Each two-foot-long link weighed about 125 pounds.
