Korea
  • 100 miles west of Inchon, Korea, submarine USS Thresher tracked a single 1,500-ton merchant ship. Thresher fired two torpedoes and both hit the ship broadside. The ship sank within a minute. (Many sources list this ship as Nissei Maru, but this identification is uncertain.) ww2dbase [Thresher | Yellow Sea | DS]
