Named after Nelson Appleton Miles, the last commander in chief of the United States Army, the massive coastal fortification was built in 1941 to defend Philadelphia, as well as oil refineries and other assets along the Delaware River and Bay. The sprawling fort and its armament were designed to fight the strongest elements of the Germany Navy, though that particular threat never reared its ugly head during the Great War. The Fort Miles Historical Association, formed in the summer of 2003 and now more than 400 members strong, is working with the state of Delaware to turn the fort into a museum dedicated to the World War II history of Delaware.
