20 August 1944:
CD-29 is assigned to the 31st Escort Squadron, Combined Fleet.

20 October 1944: Operation SHO-I-GO ("Victory") – The Battle of Leyte Gulf:
CD-29 departs Yashima anchorage towards the Philippines with kaibokan CD-22, CD-31, CD-33, CD-43 and CD-132 escorting oilers TAKANE and JINEI MARUs of Vice Admiral Ozawa Jisaburo's Northern "decoy" Mobile Force’s Second Supply Force.

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 Task Force 38’s ENTERPRISE (CV-6), ESSEX (CV-9), INTREPID (CV-11), FRANKLIN (CV-13), LEXINGTON (CV-16), INDEPENDENCE (CVL-22), BELLEAU WOOD (CVL-24), LANGLEY (CVL-27), CABOT (CVL-28) and 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’ USS STERLET (SS-392) torpedoes and sinks oiler JINEI MARU at 30-15N, 129-45E.

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 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’ STERLET. Robbins goes to full emergency power and closes to 12,000 yards but CarDiv 4, making 22 knots, outruns 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 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 TRIGGER with depth charges. Later, Harlfinger surfaces and notifies his wolf pack mates.

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 SALMON (SS-182) fires four torpedoes for two hits. The escorts counter-attack. 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. SALMON sinks to 500 feet out of control. Her diving officer finally checks her descent, but cannot hold her. Nauman decides tobattle surface and engage the escorts with SALMON’s deck guns.

SALMON surfaces in the midst of a heavy squall. Nauman’s crew quickly begins to correct a 15-degree list, puts two of 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 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. 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’ 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. CD-29 briefly chases STERLET but soon loses contact.[ 1]

20 November 1944:
CD-29 is reassigned to the Fifth Fleet.

27 February 1945:
CD-29, CD-22 and CD-68 escort minelayer TOKIWA and converted minelayer KOEI MARU that lay about 1,000 mines in an area S of Yaku Shima. [2]

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. Although there were near hits on all ships, there was almost no damage.”

Authors’ Note:
[1] STERLET, TRIGGER and SALMON each receive 1/3 credit for sinking TAKANE MARU.

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

Thanks go to Dr. Higuchi Tatsuhiro of Japan. Thanks also go to John Whitman of the USA for info on CNO intercepts of Japanese messages.
