On 5 October, the Japanese news agency Domei announced to the world that a steamer, the "Konron Maru", was sunk by an American submarine off the west coast of Honshū near Tsushima Strait, with the loss of 544 lives. The victims included two Japanese congressmen of the House of Representatives, Choichi Kato and Keishiro Sukekawa. Postwar reckoning by JANAC showed "Wahoo" sank three other ships for 5,300 tons, making a patrol total of four ships of about 13,000 long tons. The sinking of "Konron Maru" enraged the Japanese navy, and the Maizuru Naval District ordered a 'search and destroy' operation for US submarines.
