Before we consider the installation of harbor defenses at Boston in WWII, we should look at the early days of antisubmarine research there, particularly at East Point, Nahant, just to the north.

Butler details the history of the Anti-submarine Laboratory at Nahant from Detection of enemy ships by their subaqueous sound started to be investigated in the late s in Europe. However, in in the US, the Submarine Signal Company was set up in Boston to realize the commercial possibilities of underwater acoustics.

From then on limited, secret research soon began at various areas along the eastern seaboard to include Boston, Gloucester, Cape Cod, and certain military installations. Due to its strategic location and deep water, the first laboratory established to detect submarines was set up at East Point, Nahant by the Submarine Signal Company on the estates of General Charles J.

Sears, and Miss Clara Sears. Enclosed within a rectangular compound and surrounded by a tall chain-link fence topped with barbed wire, tents immediately appeared, quickly succeeded by seven wooden buildings.

Two small personnel gates and a main entrance with a sentry box allowed access and egress. The Nahant Antisubmarine Laboratory - Drawn by Gerry Butler.

The large building to the left was the existing building and the small building in front of it is the Observation Bay. There was a small personnel gate next to this. To the right are the seven laboratories and classrooms all surrounded by a chain-wire fence.

The main entrance is at the back of the property. Under direct control of the U. Navy, the laboratory was staffed with scientists and engineers from the Submarine Signal Company of Boston. Additional personnel were brought in from the Western Electric Company who was actively experimenting and building submarine-detection systems for the U.

The General Electric Company was also involved with electronic detection systems both in the US and the UK and provided scientists and engineers for the secret project as well. The Nahant facility was now on a "war basis mobilization plan" and more guards were posted in and near the laboratory while security at the station became most strict.

Armed patrols were constant all along coastal East Point and no unauthorized person was allowed to pass through the estate area or to walk the beach or rocks within view of the static shore installations.

Simultaneously, fishing and small private boats were not allowed to pass East Point at any time. Photo of the NASL taken from a newspaper report. The three closest huts incorporated laboratories and classrooms.

On May 14th,the Nahant scientists reported that they could detect propeller noises from a submarine moving nearly ten miles away. This distance, of course, included the measurement from the shore stations at East Point to static apparatus secured offshore.

Navy operations and naval personnel assigned to the secret Nahant station were then commanded by Lieutenant Hicks, USN. Beyond the structures and military systems operating at East Point, the Antisubmarine Laboratory set a new requirement.

Early in June, a number of coastal craft were destroyed or sunk, including the 5,ton steamship Carolina.

Beginning in Aprilthe Army-operated searchlight installed at the Lodge Estate for the duration of the war, was used by the First Coast Defense Command and extensively for naval experiments.

Mostly, the powerful inch light use was for target-tracking and illumination projects for the Hammond Radio Research Laboratory. In the following spring, the military auctioned some wooden buildings and structures and the site leveled.

All concrete foundations, blocks, telephone and radio support poles, and the high chain-link fence were removed and the grounds were graded and reseeded. A small guard force remained in place under the direction of Ensign Poteat, USN, while the remainder of cables and few electronic devices were removed and the site returned to its original condition.

By earlyno trace of the Nahant Antisubmarine Laboratory remained at the site or at the tip of East Point and the field remains empty at the present date.

At present, only two of the original wooden laboratory buildings remain in Nahant; the one above is located at 6 Cary Street, on the Herbert J.Edward Lansdale, working undercover as an assistant air attache at Saigon's U.S. Embassy in the mids, led the CIA's Saigon Military Mission to apply psychological warfare campaigns, such as rumors and black leaflets, against Viet MInh Communists.
