Fort Greble (Jamestown, Rhode Island)

Jamestown · Rhode Island · Spanish-American War, World War I, World War II

Quick BriefFort Greble was established as an Endicott fortification in 1897 on Dutch Island in Jamestown, Rhode Island, named for John T. Greble, the first U.S. Military Academy graduate to die in the Civil War. The fortifications featured open-topped reinforced concrete walls protected by sloped earthworks with large-caliber breech-loading artillery and mortar batteries. The fort was home to as many as 495 soldiers during World War I and several of its guns were dismounted for potential service on the Western Front in 1917–18. During World War II, Fort Greble was used as a German prisoner-of-war camp and was discontinued from service in 1947.

History & Significance

Following recommendations of the Endicott Board in the late 1890s, Fort Greble was constructed as part of the Coast Defenses of Narragansett Bay, spurred by the Spanish–American War and including tunnels and gun emplacements, with the fort enlarged until 1902. Battery Hale, the first fortification completed in 1897, contained three 10-inch disappearing guns, followed by Batteries Mitchell, Sedgwick, and Ogden.

In 1898, troops arrived to begin construction of permanent housing and facilities spanning five years, including barracks for over 300 enlisted men and significant homes for officers and their families. The fort was home to as many as 495 soldiers during World War I under the command of Colonel Charles Foster Tillinghast Sr., with several guns dismounted for potential service on the Western Front in 1917–18.

The fort remained active until the mid-1920s as part of the Coast Defenses of Narragansett Bay, when it was placed in caretaker status due to defective cisterns. During World War II, Fort Greble served as a German prisoner-of-war camp before being discontinued from service in 1947. The island is currently owned by the State of Rhode Island and designated as a wildlife management area.
