At 0400 departs Kisarazu for Saipan, Marianas as the flagship of the Higashi Matsu No. 2 convoy bound for Saipan and Carolines. 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, minelayers KYOSAI and SOKUTEN and auxiliary minesweeper TORISHIMA MARU.

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. At 0314 TATSUTA's lookouts report an incoming torpedo wake bearing 120 degrees to starboard, distance 150 meters, but it is too late to take evasive action. The torpedo hits starboard side at the forward bulkhead of the aft engine room, approximately 3 meters below the waterline. The aft engines are smashed, several sections of the hull develop cracks, the bulkhead between the engine rooms is breached and water also enters the forward engine room. The aft torpedo mont is blown overboard and the No. 3 gun mount collapses. By 0712 both engine rooms are flooded. The rudder becomes disabled and power is lost, plunging the ship into darkness.

TATSUTA's crew fights the flooding for seven hours. By 1025 the cruiser takes on a 5-degree list to port. By 1040, the rear section 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 transfer 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 order is given to abandon ship. Seconds later, TATSUTA 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 (forcibly removed from the ship by his subordinates) and ComDesRon 11, Rear Admiral Takama.

SAND LANCE's other two torpedoes hit and sink transport KOKUYO MARU carrying 1,029 troops. SAND LANCE, a thick-skinned BALAO-class, dives to 550 ft and escapes 105 depth-charges dropped by the escorts during an 18-hour attack. Garrison claims he also lightly damaged freighter TAMAHOKO MARU with his last two bow torpedoes.

10 May 1944:
Removed from the Navy List.

Authors' Notes:
[1] Mt. Niitaka, located in Formosa (now Taiwan), is then the highest point in the Japanese Empire.

[2] The attackers were in all likelihood Captain Henry T. Elrod and Captain Frank C. Tharin, USMC. Captain Elrod was killed during the fighting on 23 December 1941 in the final assault on Wake. He was awarded the Medal of Honor, posthumously. He is the first Marine to receive the medal in WW 2.

Thanks for assistance in researching the IJN officers mentioned in this TROM go to Jean-Franois Masson of Canada. Thanks also go to "Adm. Gurita" of the Netherlands.

Thanks go to Anthony P. Tully of Texas for additional details about how TATSUTA was sunk by a single torpedo. Thanks also go to the late John Whitman for info on convoy "Tei No. 3".
