May 19, 1942 (part 1)

CVL Zuiho arrived at Singapore and will require 30 days in the shipyard for repair.

Carrier Division 2 (Hiryu, Soryu, Nagumo commanding) departed Soerabaja showing Ambon as the destination, but going to the Andaman Sea via waypoints, with a refueling stop at Singapore. CVL Junyo, now passing the NE corner of Borneo, will join in the vicinity Singapore. Carrier Division 3+ will depart tomorrow.

Repair of the oil facility at Miri has been stopped at 250 (of 300), temporarily.

Edit to add: (Part 2)

BB Yamato completed construction and is ready for sea trials at Hiroshima. A pair of destroyers have been dispatched from Tokyo to escort her to Singapore.

Devious and dastardly!

I like it.

Umnak was reinforced by a US Tank Bn. I guess he's sending units to Umnak piecemeal because he has too few, and too small transports available. I would have expected a larger assault force on day 1. Whatever.

Go BIG or STAY HOME!

I've found that's the only way to play Japan to help foil Allied intel. After our carrier battle in the Banda Sea in early May he told me via email that he thought my carriers were at Truk! They WERE. And I got lucky having stopped 7 hexes from his carriers (by dumb luck); I could attack him, but he could counter only with unescorted SBDs. Scratch one flattop!

A 2 BB US TF again bombarded Adak -

A Japanese evacuation TF managed to get to Adak unmolested by these US battleships and load a fragment of a shipping engineer unit. How the TF got in I can't explain. Maybe the TF's didn't see each other at night? Why didn't the Japanese transports abort due to the combat ships in the area? Why didn't the battleships attack? Here's the situation at the end of the turn. The LCU fragment has been loaded -


And piecemeal reinforcement/resupply of the Allied force at Umnak continues with several TFs arriving today.

The Japanese force at Hengyang was reinforced across the river from the SW and East. I wasn't sure whether the cross river move would cause a shock attack so I set the force already at Hengyang to shock. It seems some of the river crossing units shock attacked, and others didn't. Anyway, the attack didn't go as well as I had hoped, probably due to the defensive forts starting off the battle at 3 -

Even after these casualties, the Japanese AV is about 2:1 and disruption and fatigue are not bad, so a deliberate attack will follow.

Another attack at Hengyang reduced the Chinese forts to 1 (combat summary not particularly important).

Transports trying to do anything in the Aleutians are being damaged or sunk by roving US cruiser task forces.

In China, three tank regiments moved west after capturing Shaoyang. When the Chinese there withdrew west, the tanks moved to encircle the defenders at Hengyang. The tank regiments entered the hex west of Hengyang at the same time the Chinese from Hengyang moved into the hex, so NEITHER SIDE CONTROLS THE HEXSIDES (as seen on the map below) -



That hex has been reinforced by infantry and more tanks from Hengyang. Why the Chinese are trying to move SW is a mystery to me!

May 25, 1942

Several air attacks on Buna and the evac TF there left the base trashed and one transport sunk. But, the evac TF escaped with a fragment of 4 Tk Rgt on board. CV Kaga completed repair at Kobe and awaits its air complement and some escorting destroyers.

A6M5 research advanced from Aug to Jul '42; research will advance to June about the middle of June. There are 8 research sites; I expect to put at least 6 of them into production. The other 2 will research the A6M5c (with armor, due Oct '44); skipping the b model, which is only slight improvement on the basic A6M5. CVs Shokaku and Zuikaku are scheduled for upgrade in June; I intend to try to time the upgrade so that when they finish their fighters will be A6M5 !

With naval attack orders and a secondary mission to attack Rangoon airfield and port, the carriers decided instead to basically take the day off! This was the sole attack mission flown by carrier aircraft (Akagi, Hiryu, Soryu, Shokaku, Zuikaku, Shoho, and Junyo) -

The Allies continued to bombard by air and sea Umnak and Ambon. Amchitka was bombarded by battleships for the first time, and Allied troops landed at Atka Is. in the Aleutians. Buna was bombed and strafed.

Sallies bombed Pegu at night, but did little damage.

May 28, 1942

Another day of the carriers not doing much, when much more was expected; could have been due to weather at sea.

A heavy cruiser TF lead by Adm Hirata attacked Allied shipping at Rangoon, sinking a PC and AM.

A Dutch CL TF bombarded Ambon.

A series of air attacks on Rangoon airfield did little damage; Betties from Victoria Point, then Sallies from Tavoy and Bangkok, then Helens from Bangkok. Carrier aircraft made a half hearted attack on a TF at Rangoon, getting one bomb hit, and even though the DL at Rangoon was 9/10, and a bunch of transports are visible in port, none were attacked!?

The Imperial Guard Div started unloading at Moulmein with escorting battleships; 56 Div is a few days down the road from Tavoy.

Both sides continued to unload troops at Moulmein, Umnak, and Atka Is.

BB Yamashiro TF bombarded Moulmein, doing negligible damage.

The CVs are returning to Singapore for refit, refuel, aircraft replenishment, and new orders. Except Kaga, recently repaired, departed Kobe, showing Singapore as its destination (ostensibly joining Kido Butai), but in fact, going to the Aleutian Islands via waypoints. Allied naval combatants there have been venturing farther and farther west, not under air cover, so we hope to pick some off.

With an amphib TF enroute, Mataram flipped, so the TF will be diverted to Ruteng.

Allied transport unloading continued at Milne Bay, Umnak, and Atka Is.

US cruisers bombarded Ambon again; the damage was significant.

Somebody (it wasn't me) hit a mine (xAK Examiner at Port Moresby)!

An amphib TF delivering an SNLF unit to Lae took some hits from several Banshee flying out of Port Moresby and 2 sank. The TF should complete unloading tomorrow, but 2 other transports are on fire and will likely sink, too.

We attacked at Milne Bay, hoping for a good result before he can get fully reinforced (our forts are 3)-

Allied troops continued to unload at Milne Bay, Umnak, and Atka Is.

Nells bombed Chungking at night inflicting exactly zero damage. Wellingtons bombed Port Blair at night with the same result.

Four US battleships bombarded Atka Is.

A small supply/fuel TF reached Port Blair unmolested.

CL Emerald took 2 fish from a Japanese sub near Rangoon.

Banshees from Port Moresby again scored hits on our evacuation TF at Buna, but didn't sink anything new. The 2 transports burning from yesterday sank, however.

Again, a fragment of this unit is elsewhere, so no PPs are required to rebuild it. The Allies approach to these 2 bases shows his extreme caution. Either or both could have been taken a week to 10 days ago, but I guess he didn't know that. Adak and Amchitka are next; maybe he'll throw caution to the wind and get cocky. Kaga is now lurking west of the Aleutian chain. Undetected.

A6M5 Zero research is at 97%. Research at Hamamatsu and Maebashi was changed to A6M5b, then A6M5c, each maintaining 30(0) status. Had these not been changed now, both would have gone into production tomorrow and a switch back to research would not have been possible. I know this because on Jun 3 five A6M5 planes were produced AND the A6M5 sites are NOT shown in blue.

CVs Shokaku and Zuikaku began their 20-day Jun upgrades at Singapore, with their A6M2 Zero fighters offloaded for upgrade to A6M5.

Jun 3, 1942

Bases assaulted today: Ruteng

Australian cruisers sank a supply PB at Buna, but the evacuation TF with part of 7 Tk Rgt escaped.

CL Dragon sucked up a sub torpedo near Moulmein.

The fragment of 1 Div at Rabaul was flown back into Milne Bay in preparation for a shock attack. But, the Allies loaded up their assault force there and left! I'm not sure if he did this or the local on the ground commander. They certainly loaded up quickly after unloading earlier in the day. Edit to add: Email intel tells me the local commander decided to skedaddle.

Tojos from Manus Is. flew LRCAP over Lae and downed 3 Warhawks with no loss. One of the Tojo pilots made ACE.

A word on logistics - transport stats during the month of May:

Resource from Hokkaido: moved 1,514,000 vs 1,050,000 excess, so finally getting into the initial backlog
Resource from China/Manchukuo/Korea: moved 741,000 vs 717,000 excess.
Resource from Toyohara/Shikuka: moved 279,000 vs. 294,000 produced (getting better with loading at Shikuka's larger port, but this backlog won't be reduced until Toyohara's port reaches level 4)

Resource to Home Islands: 2,812,000 delivered vs. 2,415,000 needed

And while we're talking about subs - I-32 fired 6 torpedoes at CV Illustrious in the Bay of Bengal, but missed. [:(] And a sub discovered a minefield at Luganville the hard way. [:(]

Six Tojos flying LRCAP from Manus Is. downed 2 unescorted Banshees at Madang. [:)]

Today the 40(0) production site at Kanasawa was changed to 0(40) production of Ha-33 engines. The third site was increased by 10, making 90 Ha-60 engines.

A few days ago 21 Div departed Shanghai by brigade in 3 task forces, all showing Adak as their destination, but in fact heading to SOPAC via waypoints with refueling at Truk.


Jun 7, 1942 (part 1)

CV Akagi and CVL Shoho departed Singapore showing Adak as their destination (to join CV Kaga), but first going to the eastern DEI via waypoints. BB Yamato and 2 other BBs (currently undetected) began moving from Ruteng to the vicinity of Ambon.

A Japanese sub put a torpedo in a tanker at Wallis Is. A Japanese sub put 2 torpedoes in a tanker east of Pearl Harbor.

CV Zuikaku's Zeroes upgraded to A6M5!

The first (of 5) Ki-61-Ia Tony research sites reached 30(0).

The airfield at Arorae reached level 1. This is an Allied base south of Tarawa and this is the first indication that it had been occupied. Wallis Is. is further south (and may also be occupied).

There were no ground attacks today while disablements at Moulmein and Kweilin are recovered.
