This photo appeared in the East Hampton Star on March 13, 1958. It is part of a collection of materials on military fortifications on Eastern Long Island. At one point, Fort Michie was built on Great Gull Island as part of Long Island's Eastern Defense Shield, but by the time this picture was taken it was no longer in use as a military installation. At this point, it was owned by the American Museum of Natural History as a bird sanctuary. Labels applied to the artillery locations on a photocopy of this photograph in another folio on the Eastern Defense Shield were provided by (Ret.) Col. John F. Bradshaw, based on World War II era fortifications on the island. Bradshaw notes the point at the top of the photograph had " 800 million candle light" searchlights. Next to the tower towards the point at the bottom of the photograph, a Battery Davis featured a 16" disappearing gun, the only one of its kind in the U.S. as of January 1983. Bradshaw also identifies the anti-aircraft gun locations, and Battery Benjamin and Battery Palmer gun locations. His annotations are available in file 30625990000812.
