The development of long-range oxygen-propelled Type 93 “Long Lance” torpedoes causes a revision of the IJN's Night Battle Tactics.

To whittle down the opposing American fleet’s numbers, the NGS plans for a special Night Battle Force to carry out these attacks. This force is to be made up by destroyer squadrons, heavy cruiser squadrons, a torpedo-cruiser squadron, and a battle-cruiser squadron. The Night Battle Force will have the fire power of several hundred Type 93 torpedoes that outrange the American battleships' main guns. The next day, after the previous night's attacks have delivered crippling blows, the IJN’s battleships will attack the remnants of the American fleet.

Makassar Strait. 55 miles S of Balikpapan. Late in the morning, AMAGIRI, paralleling OI about 600 metres off the cruiser’s starboard side, is suddenly shaken by a terrific explosion to the rear of the bridge under her keel. AMAGIRI had struck a magnetic mine laid earlier by an enemy plane. Her sound-room rapidly fills with fuel oil from a nearby ruptured tank. Luckily, the crewmen managed to escape through the blown hatch chased by the rising tide of oil. The damage is bad. Many men in the boiler and engine rooms suffer burns. On the bridge it is believed the ship was torpedoed, so extra lookouts are posted. AMAGIRI takes on a 19 degree list to starboard Fires break out and the No. 1 boiler room has to be abandoned. The torpedoes in No. 1 mount are jettisoned to prevent induced explosions. Some progress is made in combating the flames, but the list continues to increase.

AOBA orders AMAGIRI to make for Surabaya, but movement is impossible. AMAGIRI starts to lose trim forward, then oil spills into the sea and catches fire. Finally, AMAGIRI's captain orders the navy flag on her rear mast lowered. Boats ae lowered, but catch fire in the burning oil. AMAGIRI's shafts and propellers rise from the water.

South China Sea, 570 miles S of Hong Kong. Cdr (later Rear Admiral) Rueben T. Whitaker's (former CO of S-44) USS FLASHER (SS-249) is running on the surface in heavy weather. At 1046, Whitaker's lookouts spot a cruiser and a destroyer approaching at 18 knots. Whitaker crash dives, then comes to periscope depth and sets up. When the cruiser is 1,400 yards astern, Whitaker fires his four stern tubes at OI. At 1111, two torpedoes hit portside aft. One is a dud, but the other torpedo explodes and floods OI's aft engine room.

At 1114, SHIKINAMI counterattacks and drops 15 depth charges. An hour later, Whitaker brings FLASHER to periscope depth. He sees OI listing to port, down by the stern and decides to attack again. At 1326, Whitaker fires four bow torpedoes from 3,500 yards, but they all miss. Lookouts aboard SHIKINAMI see the torpedoes' wakes and the destroyer counterattacks again. Whitaker takes FLASHER deep. SHIKINAMI drops 13 more depth charges. FLASHER's crew silently reload their torpedo tubes.

At 1725, unknown to Whitaker, while he is reloading, OI sinks by the stern at 13-12N, 114-52E. SHIKINAMI rescues Captain Shiba and 368 crewmen, but another 153 crewmen are lost. Captain Shiba is later reassigned to the Naval General Staff as chief of its propaganda bureau. [2]
