It is the phrase, "Fire when ready, Gridley." the phrase was first uttered on May 1, 1898 on the bridge of the USS Olympia. "Just after midnight on May 1, 1898, the USS Olympia led the United States’s Asiatic Squadron quietly through the calm, glassy waters of the Boca Grande Channel, between the island of Corregidor and the coast of Luzon in the Philippines. The United States was at war with Spain, and the American squadron was preparing to attack a Spanish fleet in Manila Bay. As Sunday morning dawned hours later, the Olympia’s commander, Captain Charles Gridley, waited for the order to fire his ship’s guns. The order would come from the squadron’s commander, Commodore George Dewey, who watched from atop the Olympia’s flying bridge as shore batteries fired harmlessly at the advancing column of American ships. At 5:40 A.M. Dewey finally hailed Gridley with the now-famous words, “You may fire when you are ready, Gridley.”
