Sinking History
On July 22, 1943 in the early afternoon off southeast Bougainville, targeted by Allied planes including twelve B-24 and B-17s plus 34 SBD Dauntless, TBF Avengers armed with bombs. The attack was reported as "60 miles east of Buin (Kahili)". Other sources list the location as "17 miles west of Cape Alexander" or "off Cape Friendship".

At 1:45pm, as the first attack commenced by B-17 Flying Fortresses, Nisshin was at 34 knots and evaded their bombs without damage.

At 1:53pm, targeted by SBD Dauntless dive bombers and sustains three hits: one on the no. 2 turret, another on the front aircraft deck and the third inside the aircraft hangar that was open for unloading. Aboard, electrical power was lost and speed drops and temporarily jams the rudder but it is reset to the center.

At 1:59pm a third strike scores two additional hits on the port side, causing the ship to list sharply and sink by the bow. A sixth bomb hits on the starboard side. During these attacks, her anti-aircraft gunners continue to fire as the ship ship sinks. Although the order to abandon ship is given, there is not enough time for the crew or passengers to escape.

At 2:05pm the Nisshin rolled to starboard and sinks bow first at roughly Lat 6° 33'S, Long 156° 10'E. Officially, stricken from the register on September 10, 1943.
