 The "New York Times" reported that a combined arms training exercise was conducted on 26 June 1908 involving regular and militia military units from Fort Adams and Fort Greble.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.Corporal William W. Lee loaded two pounds of the wrong powder into Fort Greble's reveille gun on 2 April 1912, which typically used only 4 ounces or 8 tablespoons of black powder, and the breech blew up when he pulled the lanyard.
