NEW ORLEANS — In July 1942, about two months after Japan invaded the Aleutian Islands, a U.S. submarine on patrol near Kiska attacked and disabled the armed Japanese merchant ship Kano Maru. But the USS Grunion never returned.
An account by the Kano Maru’s military commander states that the Grunion sank after an 80 mm shell hit near its conning tower. He continued, “We saw the swell of heavy oil. All crews shout ‘BANZAI!’”
