No remnants exist today of the Dutch trading post, but a lighthouse and military buildings remain on the island.A battery for eleven 10-inch Rodman guns was also built at the south end of the island; it extended in a north-south line and had wide arcs of fire on either side.[2] However, the recommendations of the Endicott Board in the late 1890s resulted in the construction of Fort Greble as part of the Coast Defenses of Narragansett Bay.Finally Battery Ogden was completed in 1900 with its two 3-inch M1898 rapid fire guns on retractable masking parapet carriages.[1] Soldiers and their commanders launched a simulated land and sea attack on the island, and the residents of Newport and Jamestown were kept awake all night by the sound of the fort's guns.His wounds were fatal, and his grave is located in Jamestown's town cemetery on Narragansett Ave.[6] The fort was home to as many as 495 soldiers during World War I under the command of Colonel Charles Foster Tillinghast Sr. Several of its guns were dismounted for potential service on the Western Front in 1917-18.It was placed in caretaker status because the fort's cisterns were defective and could not hold sufficient water to support the garrison.
