Begin Hunt for Woman Last Seen Entering Jap Sub Disappearance of Mrs. Verna Gordon Brittain, 44, an American citizen last seen entering the conning tower of a Japanese submarine which had torpedoed the Dutch ship on which she was traveling, will be investigated thoroughly by the Japanese Government, SCAP ordered yesterday. Mrs. Brittain was on her way from Australia to Calcutta, India, in March, 1944, to join her husband when the ship was torpedoed in the Indian Ocean. Survivors reported that Mrs. Brittain and the captain of the Dutch ship were taken aboard the submarine. The submarine is believed to be the 1-8, which was under the command of Captain Arizumi, later transferred to the cruiser “Tone.” Captain Arizumi committed suicide shortly before the formal Japanese surrender. Several of the crew members of the submarine are held in Sugamo prison, but they deny any knowledge of the fate of Mrs. Brittain.
