17-20 March 1942
I'm glad to have so much supporters. Thanks.
Northern Pacific
Glens reported a convoy SE of Anchorage, sailing E, on the 19, and another W of Vancouver, sailing NW, the next day. Only Glen-carrying submarines are in the area and I am reluctant to use them to attack convoys, so I-173 left PH on the evening of the 20 to attack reported sightings in the area.
Central Pacific
During these four days, Palmyra-based B-25s bombed daily Christmas Island for a total 29 of sorties but all missed. Ki-46 flew the other way and reported on the 17th 244 Allied AC (73/43/128) on Palmyra.
The 56th and 48th Div and 1st Eng Rgt boarded tranports in PH on the 17. The next day, all ships loaded supplies and then sailed south towards Palmyra, where landing is scheduled around the 26. At the same time the KB (4 CV, 2 CVL, 1 BB, 2 CL, 6 DD, 312 AC) sailed also south with a bombardment TF (3 BB, 4 CA, 2 CL, 6 DD) but faster, planning to engage the island’s defence before the convoy’s arrival.
To prepare the operation, 45 Betties and 70 Zeroes were gathered on Johnston Island and they flew to Palmyra on the 20. Most get lost and only 3 Betties and 21 Zeroes reached the target. There was no CAP but no hits were scored.
South of California, submarines, Glens and even SIGINT signalled at least one US convoy and probably two. The CA Ashigara was still patrolling south with 3 Glen-carrying submarines. The Glens reported 2 PTs (?) on the 18 but they were not seen. On the afternoon of the 20 the Ashigara finally met an Allied ship, the troop-laden AP Meigs, which was sailing alone. She was sunk with guns and torpedoes. Ashigara wasted 3 torpedo salvoes before hitting and will SYS rising returned immediately to Hawaii.
In Hawaii Islands, the big Japanese ML TF is now busy laying mines off PH. It allready laid one minefield (1500 mines) and will lay another tomorrow. Lahaina is surrounded by 3000-4000 Japanese mines but that was not enough to stop an Allied submarine that laid a minefield here in the early hours of the 20. MSW will quickly sweep this new field.
In PH, two Japanese destroyers were upgraped while a new wreck was identified by Japanese intelligence, the AK Iowan.
Tomorrow the 2nd battle of Palmyra Island will start. The first cost me a CVE but this time it is not a raid but a full-scale invasion. The KB and the BB TF will sail 240 mines N of Plamyra and the 150 Zeroes on CAP will have to repulse the Allied aircraft. The next night and day BBs and CV aircraft will bombard the island while Zeroes from Johnston will sweep the skies.
Southern Pacific
This area will probably be the most active in the next months as Japanese ships will advance southwards from Hawaii. The theater is preparing for more action and a convoy carrying a big BF and 2 SNLF arrived on the 17 in Tarawa to turn it into an active base. 27 Zeroes arrived the same day to cover the unloading. Still on the same day a Chutai of Emily arrived in Baker Island to fly naval search mission. On the 19 Japenese engineers expanded Kwajalein port to size 5 and now have only forts to build. They will be dispatched to other islands soon.
On the 19 one of the two RO submarines patrolling south of the still Allied-held Rabaul reported a DD and an AP sailing NW, probably to this base. The DD squadron (5 modern DDs) sent to Truk precisely for such an occurrence sailed at once southwards to attack these ships off Rabaul in the night of the 20-21. They were seen the next day by a Catalina but will nevertheless proceed and try to engage this convoy.
Philippines
On the 17, the 16th Naval Guard Unit continued to land at Naga (22 casualties) under naval support by 3 DD (11 Allied casualties) and took the base in the evening in a shock attack (44 Japanese and 24 Allied casualties). The 101st USAAF Base Force retreated to Legaspi ! A wrong move, and the 16th pursued her, while the DDs were sent there to continue to pound Allied troops. Their fire hit nothing in the next 3 days but the 16th Naval Guard had now reached Legaspi and will launch a shock attack tomorrow. A Ki-21 Sentai arrived in Appari on the 19 from China to support this operation.
Naga is damaged at 41/9/38 but 92 of its 100 ressource are intact. Some Japanese AK are allready off Lamon Bay and Lingayen loading ressources for Japan.
Also two Nate Sentai (68th and 78th) will arrive shortly in PI for operationnal training. And I paid PPs to take away one more Eng Rgt from Kwantung Army. This regiment was training for Manila (allready at 40%) and was assigned to 4th Fleet command as it will then sail to SW Pacific.
Dutch East Indies
The only action was on the 18 when ten Darwin-based LB-30s of the 7th BG attacked Amboina. 15 Zeroes intercepted and shot down 3 but they got through and destroyed 2 Zeroes on the ground. After this action it was decided to upgrade Amboina to a major base and a big BF and an air HQ started to board Aps in Davao to be brought here.
The Allied AP off Kai Island is still there. A Japanese submarine is also here but didn’t attack, and Betties and Nells from Kendari and Menado also ignored it. A Ki-30 Sentai arrived in Amboina on the 20 and will maybe be more aggressive. I still suspected this ship to be a bait for my surface ships so I won’t send them here.
SE of Java lonely Allied ships were also reported each day by submarines and aircraft but no attack took place.
Japanese conquest here began to pay back and two convoys sailed for Japan from Kendari (29000 ressources) and Brunei (110000 oil). Other TK are loading in Balikpapan.
Sumatra-Malaya
Palembang was bombed on the 17 by 50 Ki-48s and 6 Nells, that hit 11 men and scored 12 runways hits. AA shot down 1 Ki-48. The same day a Catalina I flying patrol flew too close of Singapore and was shot down by a Japanese fighter.
The next day, the British SS Trusty was hit by a Ki-48 W of Georgetown. Troops boarded ships in Singapore port, one convoy leaving the same day for Kuching with 23rd Bde aboard, another loading the 55th Div and supplies to invade Akyab.
In the morning of the 19, a patrolling Ki-30 divebombed and sank the Dutch PT TM-10 off Palembang. Probably all reamining Dutch PTs are patrolling here. 49 Ki-48 and 7 Nells bombed the airfield of this base at 20000 feet but only scored 3 runway hits. In the afternoon 3 Martin 139 from Batavia attacked the surface TF covering the 23rd Bde convoys 120 SE of Singapore. 7 Oscars of 59 Sentai intercepted but only damaged one. The bombers scored one hit on a CA but it bounced and AA shot down one Martin.
On the 20 a FT TF dropped 2000 men of the Imperial Guard Div in Singkawang and then transport aircraft arrived to pick up the paratroops here (still preparing for the Bataan operation). A raid on Batavia from Singapore was cancelled by bad weather. And the first Japanese troops marching from Jambi reached Palembang (38th Div and an ART Rgt). They will bombard it tomorrow to identify the defending units before the main body of troops arrived.
In the evening the convoy of 55th Div left Singapore northwards, escorted by a BB TF (Kongo, Haruna and 5 DD).
The raid on Batavia from Singapore (67 Nells and 54 Zeroes here) will be attempted again tomorrow.
Burma
The 17th saw the successful end of the invasion of Central Burma when 35000 Japanese defeated the 22000 Allied defenders of Myitkyina and repulsed them (at 6 to 1, fort 3) towards Ledo. Both side lost about 1000 men in the final battle.
At this time the Allied forces in the area are still far more numerous than the Japanese 15th Army but are too scattered to be more than a nuisance (see the map attached below). Aerial recons on the 19 showed that only one Burmese Bde was defending the river crossing SE of Myitkyina and the 33rd Div was ordered to march there and repulse it. Troops from Myitkyina and Mandalay will surround the Allied troops (4 Chinese Div and 2 RAF BF) SW of Myitkyina, while the 21st Bde will march from Lashio to engage them. They are the main target of the 15th Army in the next two months (Chinese are excepted to last some time before surrendering), other than Akyab that will be invaded from sea by the 55th Div coming from Singapore.
The “only” danger in the are is the Allied air force. Allied engineers expanded Dacca airfield to size 5 on the 17 and 6 on the 19! Hurricanes from Akyab hit Pagan on the 18 and 19, losing 1 to AA fire and another to bad weather and scoring only one runway hit. A raid on the 19 against Mandalay airfield by 13 Blenheim IV, 13 Il-4c and 6 B-17C was more efficient, hitting 80 mens and scoring 5 hits on the base, 4 on supplies and 10 on runways. AA shot down a Chinese bomber and another was lost in a crash.
At this time the AVG was tought to have gone to China and on the 20 57 Ki-21s and 28 Zeroes from Rangoon attacked Akyab. 9 Hurricanes of 2 RAF Sqns were airborne and 6 were shot down by Zeroes for the loss of one of their number. Then bombers dropped their load and 6 more Hurricanes were destroyed, 21 men disabled and 13 hits scored on the base, 5 on supplies and 33 on runways. In the evening the Ki-21 returned to Bangkok and the Zeroes were set again to 90% CAP over Rangoon.
Activity is also rising in the Indian Ocean. The first Glen-carrying submarine (I-27) arrived there and as soon as he reached Ceylon waters reported an Allied convoy. On the 20 a Mavis from Sabang flew a recon flight over Colombo and was chased by 6 Sea Gladiators.
In green the retreat by Allied troops from Myitkyina. In red the future moves of Japanese troops.
China
On the 17, Changsha and Homan airfields were bombed respectively by 16 and 8 Ki-51, that scored 10 and 4 hits. One was shot down by AA fire over Changsha and another lost in an accident. But the main raid of the day saw 50 Ki-21, 53 Ki-49 and 26 Betties fly from Wuhan to Chungking. The raid was a failure. Ressources weren’t hit at all and only 8 hits were scored on oils. This was enough to disable 16 oil centers, leaving only 34 running. China has now not enough oil for its HI. AA fire shot down a Ki-49.
Nevertheless Chinese engineers continued to work and expanded Homan airfield to size 4 on the 17 and Changsha to size 5 on the 20. And Allied fighters finally appeared over Chungking on the 18 (9 P-40B and 40 Chinese fighters). The next day, 20 P-40B were over Changsha and shot down a Ki-15. The AVG probably went to China. Most Japanese raids were so cancelled. Only the Betty group has orders to bomb ressources in Chengtu and Canton’s Ki-51 to bomb Wuchow ressources, both are undefended. But bad weather is grounding them.
The battle of Yenen continued. Japanese artillery hit 744 men and 10 guns in 4 days, while Chinese guns disabled 9 Japanese west of the town in the same time. Two Sentai of Ki-48s and another of Ki-43 (training) bombed Chinese troops in the area on the 18, 19 and 20, hitting 52 men but losing 2 Ki-48s to AA fire and 1 Ki-48 and 1 Ki-43 in accidents.
North of Yenen the Chinese Tk Rgt moved towards the besieged city and is now just N of it. From Tatung, a Mongolian Cav Div and 2/3 of Inf Div are moving NE to take back the crossroads and then march south to Yenen.
Japan
Two US submarines of the S-class are still patrolling around Tokyo but did no attack. On the other hand they were repeatly attacked by Japanese airmen but not hit.
