Battle of Rennell Island
On January 29, 1943 a reconnaissance J1N1 Irving spotted a sizeable USN flotilla near Rennell Island. From Vunakanau, Lt-Commander Nakamura led sixteen G4M1 Betty bombers of the 705th Kokutai. Fifteen 701st Kokutai G3M2 Nells led by Lt-Commander Joji Higai took off behind them. Both formations departed an hour before sunset and proceeded at medium altitude down the slot, and in fair weather. Being slightly faster, the Bettys worked ahead of the Nells and were first to arrive on the scene. With sunset to their right, Nakamura led his Bettys around in a wide sweep to approach the U.S ships from the south, thus silhouetting the warships as targets against the horizon. With such a plan, his own torpedo-equipped Bettys should remain hidden against a dark and obscure horizon and attacked at 1919 hours.

Their torpedoes narrowly missed heavy cruiser USS Louisville however, whilst the log shows that during the attack Bunzaburo Imamura's Betty was shot down astern of USS Chicago. The attack did however take Rear Admiral Robert Giffen's Task Force Eighteen by surprise, although surprisingly no hits were achieved. In a textbook night attack, Nakamura gathered his spent Bettys, and headed them Northwest back to Vunakanau. The lack of results was as much due to bad luck as other factors.

As the Nells approached a J1N1 Irving dropped a string of parachute flares just prior to 1940 hours. The 701st Kokutai Nells immediately lodged two torpedoes into USS Chicago starboard hull, whilst others struck Louisville and Wichita, but these failed to detonate.

During the attack Higai, their Commanding Officer, was shot into the sea. Another Nell was hit, struggling back on one engine, it was clear that it would not make Rabaul. It was too dark to land on a runway, so its pilot chose to ditch, and he did so safely.

The next morning found the USS Chicago under tow at three and a half knots. Rabaul high command decided that the 751st Kokutai, temporarily based at Buka, possessed insufficient skill to launch night attacks, and so resigned to heavy casualties in a daylight raid, eleven of this unit's Bettys departed Buka afternoon to locate Chicago. They found her easily, still under tow north of Rennell Island. Lurking Grumman F4F-4s from Navy Squadron VF-10 intercepted aggressively as Nishioka ordered the attack to proceed at 1610 hours. Two Bettys fell to the Wildcats before torpedo launch, whilst another caught fire, dropped back, then crashed. However it managed to loose a torpedo against destroyer USS La Vallette prior to hitting the water.

A succession of four torpedoes struck the damaged starbord side of USS Chicago at 1624 hours, and she sank stern-first about seventeen minutes later. The Bettys withdrew quickly, but two more fell to the Wildcats. Of only four surviving Bettys, three returned on one engine - one force-landed at Munda, while the other three landed at Ballale Airfield. Ironically, the 29th January 1943 night attack constituted the last attack for the 701st Kokutai G3M2 Nells, and the unit was officially disbanded on 15th March 15, 1943.

Only four days after the Nells had lost their Commanding Officer in the attack off Rennell Island, the Commanding Officer of 705th Kokutai, Lt. Commander Mihara, was lost in a mid-air collision in poor with another Betty during a similar mission. At total of six Bettys were lost. One crewmen was rescued by a Japanese warship after having floated in the water for days in the Solomons Sea.
