St. Johns River Lighthouse was replaced by St. Johns Lightship, anchored seven miles offshore. The lightship served for over two decades, but the expense of staffing and maintaining the floating light, led the Coast Guard to build the modern St. Johns Lighthouse, which replaced the lightship on October 1, 1954.
The lighthouse was automated in 1967, and the dwellings that used to house the coastguardsmen were turned over to the Navy. (The dwellings have since been demolished.) The two attached, one-story wings, which extend south and west from the base of the tower, are still used by the Coast Guard.
The tragic events of September 11, 2001 are one of the few instances where America has been attacked on her home soil. Another such attack, also planned by foreign infiltrators, was attempted during World War II. On June 17, 1942, four German saboteurs, carried across the Atlantic by a U-boat, came ashore just a couple miles south of St. Johns Lighthouse with a supply of explosives, primers, and incendiaries to be used in a two-year assault on American defense-related targets. The men buried their boxes of supplies in the sand, and then headed north to start planning the attacks.
Four days earlier, another team of four had landed on Long Island, New York. Fortunately, one of these men, George Dasch, had second thoughts and traveled to Washington D.C., where he turned himself over to authorities on June 19. Information gathered from his interrogation resulted in the arrest of the three remaining members of the Long Island group the following day in New York City. Two members of the Florida group were captured in New York City on June 23, and the remaining two men who landed in Florida were arrested in Chicago on June 27. No attacks were carried out before the arrests were made.
A trial, held during the following month, found all eight men guilty and sentenced them to death. Dasch had his sentence reduced to thirty years in jail, and Ernest Burger, another defendant, had his sentence commuted to life in prison. The remaining six were executed in an electric chair in the Washington, D.C. Jail on August 8, 1942. In April 1948, President Harry S.Truman granted clemency to Dasch and Burger conditioned on their deportation to American Zone of occupied Germany.
The presence of St. Johns Lighthouse and the large naval force at Mayport will hopefully keep that section of the coast safe for mariners and safe from any future attacks from the sea.
