(NB: NANSHIN MARU No.30 is not part of HI-88J).
28 March 1945:
At 0730, departs Nha Trang Bay under air cover from 8 fighter planes. Alerted by Allied Intelligence, 28 strafers from the 345th Bomb Group (“Air Apache”) set out after it, but the lead plane makes a navigation error and the planes make landfall too far south, sweeping empty coastline northward from Phan Thiet to Phan Rang. One B-25 of the 501st Bomb Squadron flying cover for the mission with some fighters fights off a pass by a Nakajima Ki-43 “Oscar”, one the planes flying cover for the convoy, north of Nha Trang and is shot down at when it discovers the convoy steaming northwards Cap Varella.
At 0959, LtCdr William L. Kitch´s (USNA ´38) USS BLACKFIN (SS-322) discovers the convoy near Han Trau Nam Islets (Les Trois Rois) (12-34N, 109-28E).
At 1023, 2 miles N of Hon Trau Nam Islets, 12-37N, 109-28E, USS BLACKFIN, while in a depth of only 100 feet, starts to turn in on a freighter target for attack but is detected by nearby kaibokan CD-26.
At 1024, CD-26 drops seven depth charges which explode very close to the submarine. USS BLACKFIN sustains serious damage to her diving rudders, torpedo tubes, wireless antenna, compass and several other parts and is forced to terminate patrol two days later after conducting emergency repairs. CD-26 claims a certain kill.
At 1025, the convoy is attacked by B-24s from the 43rd Bomb Group.
At 1035, ASOKAWA MARU is attacked and suffers a direct hit in the engine room. The explosion shock blows about half the number of the shipboard gunners into the sea. All function inside the ship is lost, heavy flooding.
At 1042, ASOKAWA MARU sinks at 12-31N, 109-22E, north side of Baie de Van Fong (Van Phong Bay). 92 passengers, 8 gunners and 34 crew are KIA.
At 1219, LtCdr (later Captain) Eric L. Barr´s (USNA ´34) USS BLUEGILL (SS-242) hits HONAN MARU in stern with 2 torpedoes, at 12-40N, 109-27.5E, near Hon Doi Islet. Explosions cause 15 meters of HONAN MARU´s stern to break off, heavy flooding of engine room, unnavigable. As there is no expectations of being able to tow her, her captain orders abandon ship. Five gunners and 44 crewmen are KIA. MANJU rescues 6 crewmen while CD-84 picks up about 15 crewmen. Later this day, the wreck with her cargo of 7.700 kilolitres of unrefined coconut oil drifts ashore on nearby Hon Doi Islet.
From 1800 to 2000, the convoy shelters at Xuan Dai Bay (13-25N, 109-15E).
29 March 1945:
At 0536, USS BLUEGILL executes a second attack against the now beached HONAN MARU. Two torpedoes hit the target and flames are observed reaching several hundred feet into the air followed by a large fire throughout the ship. Later close observation showed the target to be a fire jutted wreck with after part of main deck well above water.
At 0710, LtCdr Frank M. Smith´s (USNA ´35) USS HAMMERHEAD (SS-364) torpedoes and sinks CD-84 which is sailing as tail-end charly. CD-84 sinks instantly at 14-40N, 109-16E, ca. 20 nm NNE of Pointe An Yo. 191 crewmen incl. LtCdr Ikeda Tokiyoshi and probably several survivors from HONAN MARU are KIA. CD-18 and CD-130 drop behind to rescues survivors. Nearby, the rest of the convoy is disappearing into the mist and rain about 60 miles off An Thanh.
CD-18 and CD-130, are located by a B-25 flown by Cpt Jack Jones, the CO of the 501st Bomb Squadron. Jones is leading a first wave of 15 “Air Apache” B-25s from the 498th and 501st Bomb Squadrons which has set out early this day to track down the convoy missed the previous day. 16 B-25s from the 498th and 500th Bomb Squadrons form the second wave following 30 minutes later.
Capain Jones lines up on the southernmost warship, actually the CD-18, for a bombing and strafing run and hit the stern of the escort with a 500-pound bomb as he charges over it. His wingman, 2/Lt Heath C. Steele, misses with his two bombs. CD-18 begins dropping depth charges in its wake, apparently hoping that one of the B-25s would fly into the explosions. Following behind, Lt Hardeman is forced to pull up sharply to miss the waterspout thrown up by the charges, but his wingman, 2/Lt Rico F. Pallotta, slips below him and skip a bomb into the starboard bow where it explodes. The next two planes score no hits. The 498th Squadron has, meanwhile, circled to the west. Coming out of a right turn, Cpt Cranford lead his three-plane flight directly at the ship from almost head on. His right wingman, Lt James Manners, bring his nose guns to bear and begin raking his bullets across the starboard side. Every bullet seems to hit home and two rectangular steel plates, the largest about a dozen feet long, suddenly twists from the side of the kaibokan and sails 40 or 50 feet before splashing into the sea. Cranford´s bomb hit just ahead of the ship and seconds later explodes beneath it, sending water splashing up along both sides. Following behind him, Maj Jack C. McClure, Jr., skip another bomb into the vessel, sealing its fate. By this time black smoke was billowing from a fire amidships and the kaibokan has begun to settle by its bow. Thirty minutes later survivors are seen abandoning ship. Burning fiercely, CD-18 sinks by its bow, at position 14-44N, 109-16E, ca. 35 nm SE of Cap Batangan. 184 crew incl. Cdr Shimokata Hiromaro are KIA.
While the other planes are sinking CD-18, 1/Lt Ollie E. Hatcher and 2/Lt Ralph E. Blount make a pass on the second kaibokan further north, actually the CD-130, which has begun a turn to port. Neither of them score a hit with their four bombs. Maj MacClure follow this attack with one of his own, but also miss. CD-130 is beginning to show the signs of repeated heavy strafing, however. The rest of the 501st Squadron, completing its attack on CD-18, now pounces also on the second kaibokan. Cpt Jones score a direct hit on the port bow. Lt Hardeman come in next, straddling it with four more bombs. His wingman, 2/Lt Pallotta, sore another direct hit. The 498th´s Cpt Truett C. Gowan score with two more which cause a large explosion. The vessel is dead in the water and listing sharply to starboard with fierce fires raging aboard as Lts Hatcher and Blount drop four more bombs on it. With a huge hole opened in its side, CD-130 quickly rolls over on her starboard beam ends and sinks. 187 crew incl. LtCdr Suzuki Yasukichi are KIA. LtCdr Suzuki is promoted Cdr, posthumously.With the rear guard disposed of, Captain Jones order the other planes from the 501st back to base. He has one bomb remaining so he heads for an oil tanker, actually the KAIKO MARU, which is steaming for the cover of a rain squall. Calling his wingman, Lt Steele, on the radio, he tells him not to follow since he has no more bombs. Jones then makes his run, expending his last bomb against the KAIKO MARU. Clearing this vessel, his plane immediately enters the storm. Before the ship disappears from sight, his tail gunner reported seeing a fire burning on the deck just in front of the bridge.
Lt Steele´s aircraft is right behind, reeling from heavy damage caused by flak from the escorting warships. He has disregarded Jone´s order and proceeds to cover his commander´s attack with a strafing run. His plane is one of three from the 501st that is seriously damaged during the mission. One other plane from the Black Panthers and four from the Falcons are also holed, but all return safely to base. Guided by smoke from the burning ships, the second attack wave, summoned by Col Coltharp, is now arriving on the scene. The two squadrons turn north, pursuing the main body of the convoy into the weather. As the strafers dodge in and out of rain squalls, the attack become quite confused. Numerous passes are conducted on various ships, but the pilots are often flying on instruments and there is great danger of a mid-air collision as planes become separated and fly their own courses. Several pilots find and attack targets inside the storm cells and several ships are claimed damaged or sunk. However, there is only one more certain kill. A 500th Squadron pilot, Lt John Loisel, spots an oil tanker, actually the KAIKO MARU, and attacks it through intense AA fire. He scores a direct hit and the ship erupts in a fiery explosion. He then turns away and attacks a frigate which has been shooting at him, hitting it with two bombs. The tail gunner reports that the warship is burning and listing as the plane departs. KAIKO MARU, carrying ca. 1,200 tons of crude oil, sinks at 15-14N, 109-26E, ca. 30 nm E of Cap Batangan. 12 passengers, 4 gunners and 19 crew are KIA.
During this fierce melee, at ca. 1100, MANJU is heavily strafed by two enemy planes. MANJU claims shot down one aircraft and heavily damaging the other plane which escapes burning into a squall. Three crewmen are KIA while another crewman succumbs to his wounds on 1 April 1945.
At about the same time, CD-26 is heavily strafed by and 2 crew are KIA. At 1120, subchaser CH-9 is damaged by strafing at 15-10N, 109-26E. At 1130, ca. 20 nm ESE of Cu Lao Re Island (15-23N, 109-07E), CD-134 is heavily strafed. Several crew members are killed or seriously wounded and another 30 are lightly wounded.
From 2320 to 2325, at 17-17N, 109-47E, ca. 50 nm S of Hainan, CD-134 is attacked by a USN Martin PBM-5 “Mariner” maritime patrol flying boat which conducts two bombing runs against the kaibokan. CD-134 engages the plane and shoot it down but due to near misses, the after magazine is completely flooded. Flooding causes a 5 degree list to port side but CD-134 is able to make 10 knots.
30 March 1945:
25 North American B-25 "Mitchell" medium bomber/strafers of the 345th Bomb Group ("Air Apaches") are sent out on a search mission to the south-eastern tip of Hainan – Cape Gaalong and Yulin Bay – where Intelligence hopes they will find the remnants of the enemy convoy which had escaped into the rain squalls off the Indochina coast the previous day.
By 1000, destroyer AMATSUKAZE, CD-1 and CD-26, now without a convoy, arrive inside Yulin Bay, Hainan. CD-134 arrives also at Yulin Bay later this day and lands several wounded crewmen who are taken to Hainan Naval Hospital. MANJU has arrived before noon but drops anchor off Samah.
At 1045, 12 B-25s spot and attack destroyer AMATSUKAZE, CD-1 and CD-26 at Yulin Bay. Despite a tremendous AA-barrage CD-26 suffers medium damage due to heavy strafing and near misses. CD-26 claims 3 enemy planes shot down but sustains slight damage to her hull and her communication breaks down. Later CD-26 develops a slight list due to leakages. 7 crew are KIA and another dies of wounds later this day. CD-26 is detached and conducts emergency repairs. CD-26 departs Yulin only on 15 April 1945.
31 March 1945:
At 1500, MANJU, CD-1, CD-134 and destroyer AMATSUKAZE depart Yulin for Hong Kong.
1 April 1945:
At 2100, the warships temporarily anchor at Pumice Stone Bay, SW coast of Ta-Wan-Shan Island (Great Ladrone Island), SW of Hong Kong.
2 April 1945:
At 0230, the ships depart Pumice Stone Bay for Hong Kong. At 0930, arrives at Hong Kong.
3 April 1945:
Hong Kong. MANJU is undergoing some maintenance. Together with destroyer AMATSUKAZE, CD-1, CD-134, CH-9 and CH-20, MANJU makes preparations to join as an escort for convoy HOMO-03. At 1150, 43 USAAF Far East Air Force B-24 “Liberators” bomb the harbor and sink cargos ships HEIKAI MARU with the loss of one crewman 4 nm SE of Lamma Island, 22-10N, 114-10E, and YOKAI MARU with the loss of 2 crewmen and SHOZAN MARU with the loss of 8 crewmen inside Hong Kong harbor.
When the air-alarm is sounded, MANJU weighs anchor and leaves the confined area of the inner harbor to the westward for sufficient manoeuvring space. At 1254, 1 nm NE of Green Island, MANJU is heavily damaged during the 3rd wave´s attack by two direct hits in her forecastle and just in front of the bridge. 53 crew incl. LtCdr Kamizawa Masanori (NB: surname is read Kamizawa, or maybe even Kanzawa, but not Kanazawa) and one passenger, a naval surgeon, are KIA (total 54). More than 50 of the crew are wounded, ca. 30 of them seriously. About half number of the wounded later reach Japan on board the hospital ship HIKAWA MARU. Six of the seriously wounded die later in Hong Kong hospitals, the last one on 15 January 1946!
MANJU drifts north-eastward towards Stonecutters Island. Due to the heavy damage received in the foreship, MANJU´s bow settles down and finally is resting on the bottom near Stonecutters Island while her stern is afloat.
7 April 1945:
Salvage operation on MANJU starts off Stonecutters Island.
11 May 1945:
MANJU is finally refloated and taken to Kowloon where she is dry-docked for full-scale repairs.
1 June 1945:
MANJU is attached to the 2nd China Expeditionary Fleet Escort Force.
15 August 1945:
At wars end still dry-docked at Kowloon with repairs 90 percent complete.
5 March 1947:
Removed from the Navy List.
 According to "Kaibokan Senki" (Battle History of Kaibokan Escorts), compiled by the former personnel of IJN escorts, LtCdr Ota Yoshio may have been a a predecessor CO to LtCdr Kanazawa, but if so, the date is unknown.
 Exactly why so few of USS BARB's torpedoes failed to hit such a perfect overlapping target remains a mystery. Perhaps the torpedoes were defective, a problem the U. S. Navy never got quite right during, and even after the war.
Rumors of more ships sunk persist, but they are not supported by facts.
Thanks for assistance go to Dr. Higuchi Tatsuhiro of Japan and to Mr Gilbert Casse of France. Thanks also go to Mr. Aki of Japan and Matthew Jones of Ohio for help in identifying kaibokan COs. Many thanks go to Erich Muehthaler
of Germany for the almost complete rewrite of the TROM in Revs 8 and 9.
