bridge three minutes later, and she broke in two ten minutes after the torpedo hit. Her crew and U.S. Navy Armed Guard detachment abandoned ship, different sources giving different locations for where she was torpedoed but at least one claiming they abandoned her at . One of her lifeboats foundered, but all 70 men on board abandoned her in Lifeboats No. 2 and 4 and a life raft. I-12 surfaced 30 minutes later and steered toward the lifeboats at high speed. She attempted to ram Lifeboat No. 2, and some of its occupants jumped overboard. I-12 merely brushed the lifeboat, but immediately opened fire on its occupants and men in the water who had jumped out of the boat with her 25 mm antiaircraft guns as 10 to 15 members of her crew on deck shouted Banzai! after each burst of automatic weapons fire. For 45 minutes, I-12 moved about in the vicinity of the lifeboats, attempting to ram Lifeboat No. 4, discovering the life raft with 17 survivors aboard and opening fire on it with her 25-millimeter guns, all the while shooting any survivors she found and attempting to slice up men in the water with her propellers. She then opened gunfire on both sections of John A. Johnson from a range of , and after she fired eight rounds, scoring four hits, both sections were on fire. She remained on the scene for another two hours, although she did not resume firing at the remaining survivors, who believed that she was waiting for dawn so that she could continue the massacre in daylight. Just after 01:00 on 30 October 1944, a Pan American World Airways Boeing 314 Clipper flying boat flying from San Francisco to Honolulu sighted the two burning halves of John A. Johnson, the lifeboats, and I-12 on the surface nearby. The airliner's crew and passengers also saw John A. Johnson′s bow section explode at 01:05, sending flames into the air, after which it sank. Her burning stern section remained afloat. The aircraft reported the sighting to authorities in San Francisco, who in turn notified the United States Navy patrol vessel , whose crew had heard the explosion of John A. Johnson′s bow section from away and already was headed toward the scene. A search-and-rescue aircraft sighted the survivors at 08:00 on 30 October, and at 14:00 Argus reached the scene and brought aboard 60 survivors.
