The problem I have with PT boats is that there is no example AFAIK of a DD ever disabled by PT boat 20mm or MG fire. I agree that such fire may have damaged the DD but it should almost only cause SYS damage... Few chance of FLT damage or serious fire with small calibers hits. While what we see in WITP are WITP sinking after being strafed by a PT boat some days before... I think even a DD should have armor to stop a 05in bullet fired at 1000 or 2000 yards.
When I speak of accuracy, what I wanted to say is that anybody that had been on a high-speed low boat rushing at sea will agree with me that it is a poor fire platform, as it will bouce on the sea at each wave.
6 March 1943
New Caledonia
During the night, the Dutch submarine O21 tried to attack the Japanese escort TF off La Foa but was detected by the strong escort and heavily damaged by the DD Ikazuchi that scored two direct hits and two near-misses with depth charges.
It was another bad day for Allied submarines, Kido Butai airmen launched 11 attacks against them off Noumea during the day and hit the Seadragon (twice), the Tambor and the Gar, for the loss of a Val lost in a crash.
But the main objective of Japanese airmen was again the support of the offensive on Noumea. Like the day before, the first raid targeted the port with 13 Ki-21 covered by a sweep of 21 A6M2, 6 A6M3a, 5 Ki-61 and 3 A6M3 from La Foa. They met no CAP and scored 3 hits on the docks and 1 on supplies. Then both US divisions were attacked, the Americal by 35 Ki-21, 10 Betty and 9 Ki-49 from La Foa and the 1st USMC Div by 96 Kates from the Kido Butai. AA fire shot down 7 Kates, 2 Ki-21 and 1 Betty, while two more Kates were lost in accidents. Bombs hit 127 American men and 7 guns.
And indeed the air support may have done the trick, because the shock attack of the day achieved a ratio of 8 to 1… against forts level 6….taking the base. The Japanese commander couldn’t believe that. Then reports came. Japanese losses in the last day were 2728 men, 60 guns and 8 tanks, while Allied losses were given as 27 873 men, 231 guns and 56 vehicles (strange numbers because the combat report showed 47 242 men, 560 guns and 104 vehicles, and all Allied troops were destroyed… I scored 1050 troop points, so killed around 3150 squads = 38000 men ?).
The destroyed Allied units were the HQ South Pacific, Americal Div, a part of the 1st USMC Div (cadre evacuated?), 1st and 2nd USMC Raider Bns, 1st USMC Para Bn, 7th, 8th and 9th USMC Defence Bns, 72nd USA Field Artillery Rgt, 811th and 813th Engineer Aviation Bns, 117th USN Base Force, 30th Naval Base Force and 5th Naval Construction Bn.
17 unserviceable aircraft were found on the airfield (9 PBY, 4 A-20G, 3 P-38G and 1 B-25J) while two crippled TK were scuttled in the port before the surrendering.
By the way I checked all units involved in the battle. All were at 100% OOB or more before the attack. At the end of the battle, 387 squads were missing from the cumulated OOB of the units (not counting the extra squads that I didn’t list before the battle) and 2157 were disabled. So if we count 12 men per squads, like above, Japan lost around 4500 killed and 25000 wounded in the battle of Noumea.
Noumea was seriously wrecked (port 100% damaged, airfield services 62%, runways 54%) but 1047 engineers squads were in the city and will quickly repair it.
The news were quickly sent to the naval commander aboard the Kido Butai, and orders of the fleet were quickly changed. The CV TF will sail south of New Caledonia and chase submarines with Vals and Kates. The replenishment TF will remain at sea with the BB TF, and will wait for MSW to arrive from Suva (6 fast MSW left this evening) and Auckland (5 slow ones).
La Foa airmen will fly tomorrow CAP and naval search, recon of Efate and Luganville.
Southern Army troops in Noumea also received new orders. The next step will be the attack of Luganville and Efate. Both will be simultaneously invaded to reduce the time spent here by the Kido Butai (that should allready by leaving according to the original plan).
The 65th Bde and the 17th Army HQ will garrison Noumea.
Troops already prepared at 100% for Luganville were the 18th and 53rd Div, the 27th Eng Rgt, the 14th Army HQ and 1 ART units. Three move Div (2nd, 48th and 56th), the 5th Eng Rgt, the 4th Tk Rgt and 1 ART unit received orders to prepare quickly for this operation.
Efate was also the target of some units, but far less, only the 20th Div and the 23rd Eng Rgt. And it will be the harder target, so more units having Noumea as their former target were ordered to prepare for it: 3 Div (21st and 38th Div, 1st Tk Div), 2 Eng Rgt (1st and 21st), 7th Tk Rgt, 4 ART units and the 13th Army HQ.
The plan is to invade both places at the same time with BB, KB and LBA (from New Caledonia) support, around the 20-25 March. Troops in Luganville will try to take the island fast, using the fleet support. As soon as it will have fallen, a part of the troops will be sent to Efate, where troops will have only bombarded Allied lines until now while continuing to prepare, and will attack it. At this stage most of the warships will have left the area.
New Zealand- Southern Pacific
During the night, 5 MSW swept again Allied mines off Suva. Of the two MSW TF off this base, each swept mines one day (on the 4th or the 6th) and none worked on the 5th. I should admit I had never understood how MSW TF work in WITP. Things that work once… work once, and don’t work the next time.
Bismarcks-Solomons-New Guinea
11 Beaufort V-IX and 26 P-40E from PM flew a training mission against Goodenough Island.
In the evening 33 Nicks flew from Truk to Rabaul to cover the incoming convoy bringing two more AA Bns here. I then discovered that night-fighters are not allowed in WITP to LRCAP TFs, even by day. So they will fly CAP over Rabaul tomorrow.
Japanese engineers expanded the airfield of Lunga to size 3.
Timor-Amboina-Australia
131 B-17E from Darwin attacked again Amboina and this time disabled the 10 resource centers of this base (that were all working before the raid). Weather conditions were bad and 6 heavy bombers didn’t return from this raid, all for operational reasons.
Burma
During the night, 5 Beaufighter VIF from Imphal attacked Rangoon but hit nothing.
In the morning Lashio was bombed by 27 B-17E, 16 Beaufort I and 15 Blenheim IV from Imphal escorted by 4 P-40B. They scored 2 hits on the airbase, 4 on supplies and 10 on the runway.
120 miles SE of Imphal the 1st Tk Rgt was bombed by 20 Beaufighter VIC, 9 Mk 21 and 10 Vengeance I from this base escorted by 37 P-40B and lost 33 men and 2 tanks, but one P-40 was lost in a crash..
In the Japanese rear area, the Burma Naval Squadron arrived in Singapore, refuelled and disbanded. All ships will have minor repairs, and two Kagero-class DDs will be upgraded. And the 3 AA Bns that were sent from Korea to Burma finished landing in Bangkok and will go by road and train to Mandalay.
China
There was no air raid over China today. The 13th Div marched west from Ichang and reached the retreating 49th Chinese Corps. It will attack it tomorrow to open the road leading north.
Japan
The news of the fall of Noumea arrived at the end of the celebrations of the first anniversary of the fall of Pearl Harbor (on 4 March 1942 IIRC). And a new period of official celebrations was opened by the Emperor's government.
