From Google Earth: "HARBOR DEFENSES of BOSTON Fort Dawes (1941 - 1960's) Deer Island Originally named Deer Island Military Reservation (1898 - 1941), which consisted solely of searchlight stations (1916), and fire-control and mine observation stations (1906, 1920's). WWII batteries here were Battery 105 (1944, never armed), Battery 207 (1943, never armed), Battery Taylor (1942 - 1943), AMTB Battery 944 (1943 - 1946), and an AA battery. Also here in WWII was a U.S. Navy RDF station, an HECP (1941), and a mine casemate (1944), which replaced the one at Fort Strong. All of these were destroyed by 1988 for expanding the modern waste water treatment plant. Beginning in 1948, the post was used for Air Force radar and electronics experiments, as well as Navy harbor defense functions. From 1951 - 1955, there were four 90mm AA guns emplaced here." |
