Off Conanicut Island's eastern shore lies Gould Island, the third of the major islands that comprise the town of Jamestown. It was named for Thomas Gould, who purchased the island in 1657 to use as farmland. In 1858, the Maitland family bought the entire island. After 12 years, they sold it to the Homan family, also from New York, who had the esteemed architecture firm of McKim, Mead and White design them a "cottage."
During the summer of 1911, coming off their national championship, Harvard’s football team could be seen practicing on Gould Island. Harvard’s football coach, Percy D. Haughton and his wife Gwendolyn now owned the island and a Boston paper reported that the team routinely exercised there. Following the trends of the summer social scene at Newport, entertaining was part of the Jamestown lifestyle.
The Haughtons were the last private citizens to own Gould Island. With the threat of war looming, Congress authorized the seizure of land along the eastern seaboard. Torpedoes were being developed on nearby Goat Island and a more remote place was needed for storage and testing. In September 1918, the government notified Mrs. Haughton that Gould Island was being requisitioned--they had 30 days to vacate.
In 1919, construction of hangars for seaplanes and concrete piers began. The Haughton's home became barracks for marines.
Throughout the 1940s, torpedoes were developed and tested on Gould Island. Those launched from the firing piers were followed by biplanes, tasked with retrieving the torpedoes. No system is perfect though, and Jamestown residents distinctively remember hearing torpedoes come up on the rocks. Camp Seaside's pier had a large warning light, which lit up when a torpedo was fired, giving swimmers time to get out of the water.
Although four of Gould Island's building were declared "historic" and worthy of preservation in 1975, the Navy demolished everything but the firing pier in 1999. Currently, the island is managed by The Department of Environmental Management (DEM) as a conservation habitat. It is scheduled for an environmental study to asses the viability of future development.
