22 October 1944:
Ozawa's force refuels at sea. Sound contact is made with a submarine. At 2010, carrier ZUIKAKU and light cruiser TAMA spot torpedo tracks and make a sharp turn to port. WAKATSUKI is detached to repel the sub. Ozawa is forced to cancel the refueling after receiving only one third of the required amount.

25 October 1944: The Battle off Cape Engano:
Ozawa's force is attacked by planes from Vice Admiral Marc Mitscher's (USNA ’10) Task Force 38’s USS ENTERPRISE (CV-6), USS ESSEX (CV-9), USS INTREPID (CV-11), USS FRANKLIN (CV-13), USS LEXINGTON (CV-16),USS INDEPENDENCE (CVL-22), BELLEAU WOOD (CVL-24), USS LANGLEY (CVL-27), USS CABOT (CVL-28) and USS SAN JACINTO (CVL-30).

TF 38 launches 527 sorties in five strikes against Ozawa’s Northern Force. During the day's action, carriers ZUIKAKU, ZUIHO and CHITOSE and destroyer AKIZUKI are sunk. That same day, S of Yaku Jima, LtCdr Orme C. Robbins’ (USNA ’34) USS STERLET (SS-392) torpedoes and sinks oiler JINEI MARU at 30-15N, 129-45E with all hands (69 crewmen KIA).

28 October 1944:
CarDiv 4’s HYUGA and ISE refuel from oilers at Amami-Oshima. CarDiv 4 and destroyers depart for the Inland Sea. At 2120, LtCdr (later Vice Admiral) Vernon L. Lowrance’s (USNA ’30) USS SEA DOG (SS-401) attacks CarDiv 4. He misses with six Mark 18 electric torpedoes.

That same day, TAKANE MARU is ordered to steam to Takao, but she has a faulty boiler that limits her speed to 12 knots and prevents her from complying.

29 October 1944:
CarDiv 4 and its destroyers depart Amami-Oshima for the Inland Sea. At 0415, the group is picked up on radar at 24,000 yards and tracked by LtCdr Robbins’ USS STERLET. Robbins goes to full emergency power and closes to 12,000 yards but CarDiv 4, making 22 knots, outruns USS STERLET. CarDiv 4 arrives safely at Kure.

TAKANE MARU receives new orders to proceed to Kure for repairs. At 1500, she departs with CD-29, CD-22 and CD-33 and as a separate group.

30 October 1944:
LtCdr (later Vice Admiral) Frederick J. Harlfinger’s (USNA ’37) USS TRIGGER (SS-237) picks up TAKANE MARU with her escorts and attacks. One torpedo broaches alerting the oiler that avoids the other torpedoes. At 1620, Harlfinger fires again and hits TAKANE MARU starboard aft in the engine room One torpedo heads for CD-22, but she dodges it. CD-29 counter-attacks USS TRIGGER with depth charges. Later, Harlfinger surfaces and notifies his wolf pack colleagues.

130 nm SW of Toizaki, Kyushu. CD-22, CD-29 and CD-33 are guarding immobilized TAKANE MARU. At about 2100 that night, LtCdr Harley K. Nauman’s (USNA ’34) USS SALMON (SS-182) fires four torpedoes for two hits. The escorts counter-attack. USS SALMON crash dives, but is damaged badly by a severe depth charging. Her pressure hull is dished in, an engine is knocked off its base plate, radio and radar equipment damaged and she is leaking heavily. USS SALMON sinks to 500 feet out of control. Her diving officer finally checks her descent, but cannot hold her. Nauman decides to battle surface and engage the escorts with USS SALMON’s deck guns.

USS SALMON surfaces in the midst of a heavy squall. Nauman’s crew quickly begins to correct a 15-degree list, puts two of USS SALMON’s diesel engines on line and stops some leaks. At about 2200, CD-29 sights a surfaced submarine off her starboard bow, 500 meters away. CD-29 switches on her searchlight and opens fire with her 120-mm bow gun, but loses the target after the first salvo. At 2235, CD-22 and CD-33 arrive and attack USS SALMON from different directions. CD-22 charges the submarine intent on ramming. Nauman, in turn, charges the kaibokan. The two vessels pass each other just 50 yards apart. CD-22 opens fire on the submarine with her 25-mm AA gun. USS SALMON’s machine-guns, 20-mm AA and deck guns return fire and kill four of CD-22's sailors and wound another 14. CD-22 is also hit in the bow by a dud shell that causes a temporary leak. Her speed drops to 11 knots.

31 October 1944:
SW of Kyushu. At about 0100, LtCdr Robbins’ USS STERLET finds TAKANE MARU dead in the water and down by the stern. No escorts are in sight. Robbins fires six torpedoes by radar bearings and gets four hits that finish off the oiler. TAKANE MARU sinks at 30-09N, 132-45E. She was carrying 66 crewmen and an unknown number of passengers. CD-29 briefly chases USS STERLET but soon loses contact.[ 1]

Tanker NANSEI MARU No. 1 is also sunk with unknown casualties and cargo ship KIYO MARU is damaged. They also sink auxiliary sailing vessels KAMO and TENJIN MARUs bound for Okinawa at 31-24N, 130-07E.

At 1912, USN codebreakers intercept and decrypt a message that reads: “While CD-29 and CH-58 were escorting 6 merchant vessels at Sakurashima anchorage, enemy carrier based planes attacked. 1. At 0730 eight planes attacked. Two planes shot down. Japanese losses, none. At 1330, seven planes attacked convoy. One plane shot down. KENYO MARU received a hit and sank.

Authors’ Note:

[2] USS KETE may have struck a mine at that same place.

Thanks go to Dr. Higuchi Tatsuhiro of Japan and Mr. Gilbert Casse of France. Thanks also go to the late John Whitman of the USA for info on CNO intercepts of Japanese messages.
