The convoy includes ATLANTIC, AWA, DAITEN, HIBI, MIHO, RYUKA, KOKUYO, TAJIMA, TAKAOKA TAMAHOKO and TSUSHIMA MARUs and SHINSEI MARU No. 1 escorted by destroyers ASAKAZE, NOWAKI, UZUKI and YUNAGI, kaibokan HIRADO and minelayers KYOSAI and SOKUTEN.
To reinforce the Marianas Comdesron 11 flag in Tatsuta, with Nowaki, Yunagi, and Uzuki guarding 12 transports of the To-Matsu NI-GO convoy left Kisarazu gathering place at 0400 12 March 1944, bound for Saipan. However, while sailing southward, Tosho NI-GO convoy vessel KYOKUYO MARU also hit and sunk in same attack, but then on the March 19 the convoy arrived at Saipan.
That same day, LtCdr Malcom E. Garrison's new USS SAND LANCE (SS-381) on her first war patrol, receives an "Ultra" message from ComSubPac about the approaching convoy.
13 March 1944:
40 miles S of Hachijo-jima. LtCdr Garrison has six torpedoes left. At 0310, he sets up and fires his four stern torpedoes at the light cruiser. TATSUTA's lookouts detect a torpedo trace bearing 120 degrees to starboard, distance 150 meters, but too late for evasive action. A single torpedo hits starboard side three meters below the waterline under the rear TT mount at the front of the aft engine room. The aft engine is smashed, several parts of the hull cracked, the bulkhead between the engine rooms breached and water also enters the forward engine room. TATSUTA's machinery is soon flooded. The rudder becomes disabled and power is lost, plunging the ship into darkness.
SAND LANCE's other two torpedoes hit and sink transport KOKUYO MARU carrying 1,029 troops. TATSUTA's crew fights the flooding for seven hours, but takes on a seven degree list to port. By 1040, the aft part of the upper deck is awash. The flooding is temporarily halted, but begins again. At 1415, TATSUTA takes on a starboard list, so her crew is ordered to shift all weight to port. By 1510, her stern is settling faster and the starboard list is increasing slowly. At 1536, the list is 60 degrees starboard, and the cruiser is rapidly sinking. Seconds later, she goes down by the stern at 32-52N, 139-12E. Twenty-six men are KIA, 10 wounded. Destroyers NOWAKI and UZUKI rescue the survivors including Captain Shimazui and ComDesRon 11, Rear Admiral Takama.
SAND LANCE undergoes an 18-hour attack by the escorts. SAND LANCE, a thick-skinned BALAO-class, dives to 550-feet and escapes 105 depth-charges dropped by the escorts set to detonate at 250-feet. Later, SAND LANCE makes port at Pearl Harbor. Garrison claims he also lightly damaged freighter TAMAHOKO MARU with his last two bow torpedoes.
