Fort Andrews

Fort Andrews. Located on Peddocks Island in Boston Harbor, this Endicott Period fortification was a major component of the Harbor Defenses of Boston. Constructed between 1897 and 1904, it was designed to mount powerful coastal artillery batteries to protect the strategic Port of Boston and its vital naval facilities. The fort was actively manned through both World War I and World War II before its eventual decommissioning in the mid-20th century.

History

The establishment of this fortification was a direct result of recommendations made by the Endicott Board in the late 19th century, which called for a massive modernization of United States coastal defenses. The United States Army selected Peddocks Island for its strategic position commanding the main ship channels into Boston. Construction commenced in 1897 under the supervision of the United States Army Corps of Engineers. The fort was named in honor of Major General George Leonard Andrews, a distinguished Union Army officer and former professor at the United States Military Academy. Its activation coincided with a period of rapid technological advancement in naval gunnery and the growing geopolitical influence of the United States Navy.

Design and construction

The fort's design was characteristic of the Endicott Period, featuring dispersed, concrete-reinforced gun batteries and underground magazines to withstand modern naval bombardment. Key batteries included Battery Bumpus, armed with two 12-inch guns on disappearing carriages, and Battery Whitman, which housed 10-inch guns. Support structures were built from durable materials like granite and brick, with a central parade ground surrounded by barracks, officer quarters, a hospital, and a power plant. The construction process involved significant land excavation and the creation of an extensive network of narrow-gauge railway tracks to move heavy materials and ordnance across the island.

Military use and operations

Manned by the Coast Artillery Corps, the fort was part of a integrated defense network that included Fort Warren, Fort Strong, and Fort Revere. During World War I, its garrison was reduced as personnel were transferred to field artillery units on the Western Front, and some of its larger guns were removed for potential use as railway artillery. In the interwar period, it remained an active training post. Activity surged again during World War II, with the fort serving as a key harbor defense command post and mounting modern anti-aircraft guns. It also functioned as a barracks and support facility for troops destined for the European and Pacific Theaters.

Decommissioning and legacy

With the advent of air power and ballistic missiles rendering fixed coastal artillery obsolete, the United States Department of War declared the fort surplus in 1947. The property was transferred to the Commonwealth of Massachusetts. Most of the heavy guns and valuable metal fixtures were removed for scrap during the Korean War mobilization. For decades, the site lay largely abandoned, its structures succumbing to vandalism and the harsh New England weather. Its historical significance was recognized when it was listed on the National Register of Historic Places as part of the Boston Harbor Islands National Recreation Area.

Present day

Today, the fort is managed by the Massachusetts Department of Conservation and Recreation as part of the Boston Harbor Islands State Park. While in a state of stabilized ruin, many of its concrete batteries, crumbling barracks, and overgrown administrative buildings remain accessible to the public. The island is reachable via a ferry service from Long Wharf, operated by the Massachusetts Bay Transportation Authority. It is a popular destination for historical tourism, birdwatching, and kayaking. Preservation efforts are ongoing, led by partnerships between state agencies and nonprofit organizations like the Friends of the Boston Harbor Islands, aiming to conserve the site as a monument to early 20th-century American military engineering.
