24 October 1944:
Destroyer AKIKAZE departs Kure to lead the escort of the Second Supply Force.

25 October 1944: The Battle off Cape Engano:
Ozawa's force is attacked by planes from Vice Admiral (later 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), LEXINGTON (CV-16), USS INDEPENDENCE (CVL-22), USS 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 (Captain [Vice Admiral posthumously] Kaizuka Takeo (46), forty-eight officers and 794 petty officers and men lost), ZUIHO (six officers and 208 sailors lost) and CHITOSE (Captain [Rear Admiral posthumously] Kishi Yoshiyuki (47) and 903 officers and men KIA) and destroyer AKIZUKI (183 sailors KIA) are sunk.

28 October 1944:
Oiler 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:
TAKANE MARU receives new orders to proceed to Kure for repairs. At 1500, she departs with CD-33, CD-22 and CD-29 as a separate group.

30 October 1944:
LtCdr (later Vice Admiral) Frederick J. Harlfinger’s 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 mates.

130 nm SW of Toizaki, Kyushu. CD-33, CD-22 and CD-29 are guarding the 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-33 and CD-22 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’ (USNA ’34) 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 with no survivors. CD-29 briefly chases USS STERLET but soon loses contact.
