3 September 1943
Northern Pacific
The last Japanese submarine operating between the Kuriles and the Aleutians, the I-155, was chased during the night by two SC groups and sunk by two hits and five near-misses.
The CL Natori and 4 DD swept waters off OJ during the night and surprised two PT TF (7 and 14 PT), sinking three in the first clash and four in the second. Only two PT fired torpedoes (in the second battle) and missed. This TF then retired at full speed towards Shikka and was attacked after dawn 180 miles ESE of this port by the SS USS Redfin, but she was seen by the escort and chased away by the 4 DD, even if she escaped unhurt.
During the night another Allied bombardment TF attacked PJ but with only three CL (USS Minneapolis, HMS Newcastle and HMAS Hobart) and seven US DDs was unable to defeat the Japanese coastal guns and only hit 124 guns and 5 guns, but was able to retire without damage.
Tanaka’s surface TF sailing with the KB was supposed to react but never received orders to do so and so remained with the CV TFs following the convoy supply NW of OJ and PJ. During the night the submarine USS Dragonet tried to attack this fleet 120 miles WNW of OJ but was chased by two DDs.
The KB with Tanaka CA Tf and the supply convoy was during the day 60 miles NW of PJ. The Allied ships seen today were in two groups. From 180 to 300 miles west of Kiska there were a dozen of TF either retreating transports, damaged ships or SC TFs. 420 miles west of Kiska (and so 240 miles ESE of PJ) cruised the Allied CV TF. 2 PT TF and 4 submarines were off OJ, two submarines off PJ and 5 other submarines scattered NW of PJ.
So both enemy CV TFs were out of range of each other, and neither reacted. The KB airmen busied themselves by searching Allied submarines, launched around 15 attacks and damaged two, the USS Permit in the morning 180 miles WNW of OJ and the USS Gato twice in the afternoon near the KB. In the morning the KB was attacked by 13 B-24D from Attu. A CAP of 155 A6M3a, 49 A6M5 and 30 A6M2 was defending the fleet and repulsed the attack, shooting down ten of the Liberator, but losing to return fire 5 fighters (3 A6M2, 1 A6M3a and 1 A6M5) and 3 pilots. The CAP scored three more victories during the day against Allied patrols, shooting down a PBY, a TBM and a Barracuda. ENS Fujita I of BI-1 Daitai became today the best living Japanese ace (and the 3rd overall) by shooting down 3 B-24D and an Allied patrol aircraft over the KB and so reaching the score of 28 kills.
79 G4M1 from Toyohara bombed the new Allied base of OJ today. They met weak AA defenses and their only two losses were operational. This attack disabled 596 men, 1 gun and 5 vehicles and scored 4 hits on the port and 5 on supplies. OJ showed again port damage (now 8) at the end of the day. So still no work on fortifications or airfield. To continue to keep them honest there will no naval bombardment tonight because of the arrived PT (that will probably lack fuel shortly). Tomorrow the G4M1 of Toyohara will fly the naval search missions while the 60 G4M2 based will continue to bomb the Allied base.
PJ was not bombed during the morning and sent 5 Nick to attack unsuccessfully PT off OJ, while a PBM Mariner coming for a recon of the base was shot down by AA fire. But in the afternoon a huge Allied raid targeted the airfield. Allied CV sent 110 SBD, 54 TBM, 16 TBF and 8 Barracuda escorted by 27 F6F, 17 F4F-4 and 6 Hellcat II that met 107 Japanese fighters on CAP (31 A6M3a, 29 A6M3, 9 A6M2, 9 Rufe, 8 A6M5, 8 Tony, 7 Oscar, 6 Tojo). Local units were helped by three Zero units from the nearby KB.
Japanese fighters suffered 40 losses (9 A6M3a, 7 A6M3, 6 Rufe, 5 Tojo, 5 Oscar, 4 Tony, 3 A6M2 and 1 A6M5) but shot down 93 Allied aircraft (25 SBD, 21 TBM, 20 F6F, 17 F4F-4, 5 TBF, 3 Barracuda and 2 Hellcat II). The raid anyway reached the airfield and destroyed 35 Japanese aircraft on the ground (10 A6M3, 9 A6M2, 4 Nick, 3 Tony, 3 Rufe, 2 Tojo, 2 Oscar, 1 A6M3a and 1 Helen), did 62 casualties and scored 12 hits on the airbase, 1 on supplies and 48 on the runways. AA fire shot down 4 SBD and 3 TBM, and with the final loss of 1 SBD to engine failure, the final score for this raid was 101 Allied aircraft and 75 Japanese destroyed.
Two of the Japanese big scorers were involved in this battle: WO Hori M of F2/Tainan, who was with this unit since the start of the war and scored his first victory in December 1941, scored 3 kills to bring his score to 21 but was then himself shot down and killed. The ENS Banno V of AI-1 shot down 3 Allied bombers to raise his score to 19.
The detailed unit situation in PJ was the following (including the three KB units that took part in the battle):
204 Sentai scored no kill and lost 7 Oscar II and 4 pilots
246 Sentai scored 4 kills and lost 7 Ki-44 and 3 pilots
244 Sentai scored 5 kills and lost 7 Ki-61 and 2 pilots (one WIA)
13 Sentai scored no kill (didn’t fly) and lost 4 Ki-45 but no pilot
F2/Tainan scored 8 kills and lost 8 A6M3a and 6 pilots
F4/Toko scored 8 kills and lost 12 A6M2 and 2 pilot (one WIA)
F2/6th scored 10 kills and lost 13 A6M3 and 4 pilots
F1/2nd scored 9 kills and lost 4 A6M3 and 1 pilot
FF7/Yokohama scored no kill and lost 5 Rufe and 2 pilot (one WIA)
FF1/452nd scored no kill and lost 1 Rufe and its pilot (WIA)
FF2/452nd scored 2 kills and lost 3 Rufe and 1 pilot
AI-1 scored 7 kills and lost 1 A6M3a but no pilot
DII-1 scored 17 kills and lost 2 A6M3a and 2 pilots (one WIA)
JI-1 scored 18 kills and lost 1 A6M5 and its pilot (WIA)
So the losses for this day were 9 IJAAF pilots (at least one only WIA) and 20 IJNAF pilots (at least five only WIA).
On the ground at PJ, both sides continued to exchange artillery fire. Allied losses were 13 men, Japanese ones 325 men and 10 guns. Allied troops on the island numbered 192 527 men (+ 1 138), 2046 guns (+20) and 414 vehicles (+2) for 3544 AV (+62), against 79 609 Japanese men (+1 458), 716 guns (+32) and 4 tankettes for 1537 AV (+36). A Tina was lost in an accident while flying troops to this island from Toyohara.
The evening report of PJ showed damage of 16/2/0 (airbase/runway/port), 416 engineers (+4) and 36 734 supplies (-1194). At the end of the day PJ airfield had 88 fighters (76 available), 11 Rufe (6 available) and 11 Nick (7 available) to defend itself. No more reinforcement was available immediately but a Rufe Chutai and the A6M2 Daitai were sent to Toyohara to receive replacement aircraft (18 A6M2 pilots and 3 Rufe one had no more AC). Also 12 replacement fighter aircraft arrived but were not serviceable. Tomorrow the base will have 109 aircraft able to fly CAP (78 available).
The damaged submarine I-156 reached PJ with damaged 36/81 and was disbanded in the port. So she might be saved or draw some bombers that won’t try to bomb Japanese CV or the local airfield.
More east the admiral Nagumo was hesitating to start a new CV battle. Japanese services estimated that the Allied CV fleet was composed of the American CV Hornet, Enterprise II, Essex and Intrepid, the British CV Victorious and Indomitable and the CVL USS Belleau Wood for a total of around 480 aircraft. Around 200 should be fighters and of this number 21 were lost yesterday and 38 today. While around 120 Allied bombers were lost in the last four days. So the Allied CV TF was probably in need to sail back to base. And if it didn’t and remain on position it should be an easier target than it will ever be.
So rather than ordering the supply convoy to sail to PJ, Nagumo directed it to 120 miles EAST of PJ. The KB will follow it and DB and TB were ordered to fly naval attack at range 4. So they will be able to engage the Allied CV if they remained in the area, or an eventual Allied bombardment TF ready to hit PJ again. Fighters will fly CAP 60%. The fleet had this evening 299 fighters (293 available), 78 dive-bombers (78) and 84 torpedo bombers (84). Tanaka transferred a CA and a CL to each CV TF to increase AA defenses, and kept 1 CA and 1 CL and 6 DD as a surface TF to escort the CV. The four new submarines arriving in the area will sail east, outside of the Allied shipping lanes but ready to sail north if Allied CVs were hit.
More west the BB TF refueled in Shikka and completed shell cases but didn’t replace torpedoes (no AD here, and port 6 is not enough). It will sail SE and meet tomorrow off Shimushiri Jima (the island 120 miles NE of Etoforu Jima) the Mutsu and her escort. This will allow it to avoid the numerous submarines seen today on the way between Shikka and OJ (at least 8).
The Yamato TF will join the fleet in a little less than a week. It was joined today by five more repaired DD in Kitakyushu.
The damaged ships in Shikka repaired FLT damage with the assistance of the local ARs. The DD Kasumi was now at 60 miles from Shikka with damage 54(+6)/76/2(-6). The floatability damaged didn’t increase again today. It seems that at least one Japanese crew knew that water going inside a ship is a bad thing. The CVL Ryujo reached Shikka in the afternoon and was docked with damage 43(+1)/55(+3)/2(-5). Her 33 remaining aircraft (26 A6M3a and 7 Kate) were unloaded by crane and brought to the local airfield. The damaged APD-34 had attempted to sail alone from Etorufo Jima from Ominato, starting with FLT 54, but sank today near Ominato.
Southern Pacific
The reorganization continued. In Noumea three AP loaded the 149th IJA BF and will carry it to Luganville where it will relieve the 3rd Base Force that will then be shipped more north.
New Guinea-New Britain- Solomon Islands
During the night three Allied MSWs swept the Japanese minefield laid SE of Lae. During the day the Dinah flying the daily recon of Lae reported that the CAP had been reinforced here by 13 Corsair that new flew together with around 20 F4F-4.
Allied airmen continued to be active above Rabaul an Kavieng for a total number of 272 sorties. 10 Beaufighter Mk 21 from Kiriwima attacked barges off Rabaul, sank one and heavily damaged another. This airfield was attacked by 41 Beaufighter Mk 21 and 21 B-25C from Kiriwima escorted by 22 P-38G and by 23 B-25J from Gili Gili and reported 93 casualties, 1 disabled gun, 2 hits on the airbase, 1 on supplies and 68 on the runways. Rabaul AA gunners shot down 2 B-25J and 1 B-25C. Kavieng was attacked by 58 B-24D, 28 PB4Y, 20 B-17E and 12 B-25C from Dobadura escorted by 37 P-38G and by 3 PB4Y and 2 B-17E from PM and reported 37 casualties, 12 hits on the airbase, 8 on supplies and 64 on the runways. A B-24D and a B-25J were lost in accidents.
The blockade runner Shinetsu Maru was bombed in the afternoon by a patrolling B-24D 60 miles NE of Kavieng and damaged at 17/19/5 but will go to this base tomorrow to unload under bad weather cover.
Rabaul reported in the evening damage of 100/86 (airbase/runway) and 3595 (-73) supplies for 4980 (+3) required, Kavieng was damaged at 34/15.
Two submarines (I-176 and the Glen-carrying I-31) will return to the Allied shipping lanes south of Gili Gili.
Timor-DEI-Australia
In the afternoon Koepang was attacked by 18 B-25C from Derby and 84 B-17E and 32 B-24D from Darwin. The base reported 138 casualties, 4 disabled guns, 21 hits on the airbase, 5 on supplies and 141 on runways. And 14 B-25C from Darwin escorted by 5 P-40N raided Lautem and did 13 casualties while scoring 10 hits on the runway. A B-24D was shot down by AA fire over Koepang and a B-17E was lost in an accident.
A damaged barge off Lautem was near-missed by a patrolling PB4Y and then strafed by 14 Brewster 339D from Darwin but was still alfloat at the end of the day.
The evening area report listed the airfield status as: Maumere OK (fort 2, 31%), Koepang 41/65/0 (system/runway/port), Dili 88/52/0, Lautem 89/33/38, other bases undamaged.
The planned attack on Tenimbar wasn’t launched as there were no more ships off this base and the aircraft gathered to attack them were scattered in the evening. 21 Betties and 20 A6M3a were sent to Palau where they will form a reserve able to fly to Kendari, Truk or Hollandia. The other A6M3a will rest one more day in Kendari.
SRA
The “Gold Convoy” will arrive tomorrow in Palembang. It sent 6 AK to Toboali and an ASW group to chase an Allied submarine reported 180 miles north of Singkawang, Borneo.
The convoy of small AK carrying 59k resources from Saigon arrived in Hong Kong, refueled and sailed to Japan along the Chinese coast.
Burma
After having been totally grounded yesterday by bad weather and not being able to support the Allied attack Allied airmen flew 492 sorties today, all to Myitkyina: 10 B-25J and 37 escorts from Ledo on the airfield (41 casualties, 1 hit on the airbase, 2 on supplies and 15 on runways), and 130 fighter-bombers (Vengeance included), 244 bombers and 71 escorts against 3 divisions of the garrison (657 men and 10 guns hit). A B-24D, a B-25C, a B-25J, a Blenheim IV, a Beaufighter VIC and a P-40E were lost in accidents. On the Japanese side a Dinah III was shot down by AA fire over Ledo.
On the ground Japanese guns pounded Allied troops in Katha (82 casualties) and Allied guns Japanese lines in Myitkyina (135 men hit). 1556 Japanese AV (+15) faced 1434 Allied (+7) in Katha, and 1968 Japanese AV (-73 in two days) faced 2663 Allied (-368 in two days despite the arrival of a Chinese Corps) in Mytkyina.
The evening report showed damage in Myitkyina as 19/0. In this town there were 4266 remaining supplies (-282) for needs of 11668 (-1701).
28 Ki-61 of the experienced (level 75) 68 Sentai left Rangoon in the evening. They will go to the Kuriles front and flew today to Changsha, China.
China
Training raids continued to target 50th Chinese Corps NW of Changsha. 80 training sorties (+ 29 escort sorties) were flown from Wuhan and hit 96 men without loss.
Japan
The 156th IJN Base Force was created today in Tokyo and boarded the same day ships that will carry it to Shikka.
