Submarines "Sank" Fleet.

New York Times 100 years ago today, May 25, 1913:
Torpedo Attack Successful in Mimic Battle Off Newport.
    NEWPORT, R.I., May 24.— Eleven of the biggest battleships in the United States Navy, constituting the Atlantic squadron, were sunk theoretically to-day in an encounter with five submarines off Block Island Sound. The attack took place three hours after dawn, and under cover of a dull sky and streaks of fog.
    The battleship fleet expected the attack, and all hands had been mustered to quarters when the gray back of an under-water craft heaved out of the sea off the port bow of the flag-ship Wyoming. Before the guns of the flagship could be trained on the "enemy" a dummy torpedo struck the Wyoming on the port side, well below the water line. The 20,000-ton warship, which cost several millions to build, foundered, carrying down the greater part of her 800 men, according to the umpires.
    One by one the other battleships were torpedoed and sent to the bottom, and the fleet returned to Narragansett Bay with the submarines carrying the honors of make-believe war.

    PORT TOWNSEND, Wash., May 24.— Announcement was made to-day of remarkable results of target practice yesterday with the 12-inch mortars at Fort Worden, one of the defenses at the entrance to Puget Sound. The mortars were fired for the first time at fixed and movable targets in Discovery Bay, eight miles distant and hidden from the fort by forest-covered hills. The exact score has not been computed, but several shots were marked at hits.
    The importance of fortifications commanding Discovery Bay has long been recognized, but it was not thought that the bay could be covered by fire from a distant fort. Just how the shots were directed is known only to the officers, but they were probably fired from a concealed station on Protection Island.
