20th century to the present There was a burst of military fortification activity from 1890 to the end of World War I. The Spanish–American War was a catalyst, beginning in 1898, and work began on Dutch Island's Fort Greble. The War Department bought for Fort Getty, and fortifications were quickly erected. Summer homes were condemned near Fort Dumpling to establish Fort Wetherill. More land was acquired at Prospect Hill near the Conanicut Battery site for an observation and fire control station, and the government established a torpedo station and test facility on Gould Island. Then, at the end of the First World War, the Conanicut Island fortifications fell into disuse. World War II brought establishment or reactivation of military bases around Narragansett Bay, including Forts Getty, Burnside, and Wetherill on Conanicut Island, Fort Greble on Dutch Island, a torpedo factory on Goat Island, and a torpedo station on Gould Island.
