Fort Duvall
The long range guns of Fort Duvall could cover an arc running roughly from Gloucester in the north down to Plymouth in the south, and extending well out to sea. Hidden behind the bluff at Point Allerton, the fort could not be observed from the sea. Fire for the guns was directed and observed from the tall fire control tower at Point Allerton, which survives to the present (2010) under private ownership.
At the time of Battery Long's construction, the next largest guns were the barbette-mounted 12-inch guns of Battery Gardner at Fort Ruckman in Nahant, MA. Later, two more 16-inch guns were added in Nahant and made up Battery Murphy. A third pair of 16-inch guns was planned for Fort Dawes on Deer Island, but after the emplacements were constructed at the outset of WW2, the tubes for this battery were never delivered. Instead, in the early 1940s, many of the longer-range 10-inch and 12-inch batteries of the harbor defenses (including the major batteries at Fort Revere in Hull, just north across the water from Fort Duvall), plus all of their 12-inch coast defense mortars, were decommissioned and scrapped.
