On 12–13 December 1981, a newspaper published a description of the scramble among several groups of scientists and treasure hunters over a wreck found in 1976 on a shallow reef of the Caicos Islands and believed by some to be the “Pinta”, one of the three ships that sailed with Columbus in 1492. On 28 August 1981, the same paper announced the discovery and impending removal of seventy-two rotting wooden hulks lying on the seabed off the coast of Southern Japan near Nagasaki. It has been contended that these hulks are the remains of the fleets with which Kublai Khan vainly attempted to invade Japan in 1274 and 1281.a Similar notices appear with increasing frequency in the international press. In 1980, for instance, the discovery of the wreck of a Czarist warship, the “Admiral Nakhimov”, sunk in the Strait of Korea during the Russo-Japanese War of 1904–1905, was announced; it is rumoured that the ship carried an enormous treasure of gold, platinum and other valuables. This discovery led to a heated controversy between the Soviet Union and Japan, in the course of which the former asserted that the salvage operation planned by a Japanese businessman would amount to “an act of piracy”, the vessel having retained its character as a Russian warship and, therefore, the sovereign immunity attached to it. Another event which provoked considerable argument was the partly successful attempt by the United States research vessel “Glomar Explorer” to raise the wreck of a Soviet submarine which had sunk 1,000 miles north-west of Hawaii in 1968.
