We're slowly getting back into this.

There's little I can do now in the Aleutians, as the Japanese carriers and battleships are occupied with the invasion of Java, Ambon, and Burma. I'm using air transport to pull fragments from units at bases with airfields. There has been sporadic reinforcement of Dutch Harbor and some attacks, but both sides have comparable AV.

At Changsha, the Chinese forts have been reduced to 2, so continual aerial bombing has commenced to keep it from increasing.

Mar 12, 1942

A6M5 Zero research advanced 1 month, from April to March, 1943. It will continue to advance one month every 14 days (+/-), so production is projected to start sometime in July '42. A6M3 (due Jun '42 and not CV capable) and A6M3a (due Dec '42) are, therefore, irrelevant.

Japanese cruisers attacked at Rangoon, sinking 3 (probably empty) transports -

A US sub fired 4 torpedoes at CVL Shoho near Morotai, and missed.

The Japanese force voluntarily evacuated Ichang after several days of marching in combat mode. Since the Chinese had a more than 3 to 1 advantage in AV, I had expected to be attacked (and severely mauled) at any time.

A US Marine Bn landed at Umnak Is. and one of the transports hit a mine -

BB Nevada bombarded the Japanese troops at Dutch Harbor; 4 other battleships bombarded the Japanese troops at Umnak. The Marine Bn fragment at Umnak was destroyed by deliberate attack.

In China, 7th Chinese Corps surrendered to 9th Armored Car Co. This corps was one that started near Sinyang and has been chased all over central China.

The Allies withdrew and Salamaua flipped.

A 3 BB TF (Nagato, Yamashiro, and Ise) encountered PT and MTB TFs at/near Namlea, sinking 1 of each in 3 engagements.

Sub I-156 put 2 torpedoes in BB Resolution, which has been reported sunk. If not, it can't go into Rangoon for repairs, and may have difficulty getting back to Colombo -

Mar 17, 1942

Bases captured today: Pingsiang (RES 120(0)), Dobodura, Kokoda, Makassar (RES 17(3))

Bases assaulted today: Ambon

The 3 BB cover TF at Ambon did their job, reacting to a 4 PT TF and sinking 1, and a 7 MTB TF and sinking 5. The transports unloaded completely, suffering some damage from the CD guns, and will retire tomorrow. 48 Div (+) should have no difficulty capturing Ambon from the ragtag collection of defenders.

Eight British light cruisers bombarded the Japanese troops at Moulmein, but did little damage (the Allies still hold the base) -

A deliberate attack at Batavia reduced forts to 1. A deliberate attack at Pingsiang (I guess I forgot to change to shock, as I said in the previous post), captured the base even after being bombed by B-17s from Chungking -

Mar 18, 1942

Bases captured today: Ningsia

Probably because of 0% moonlight, in several surface engagements near Ambon one or both sides were able to evade combat.

Subs put torpedoes in an xAP and AMC near Ceylon.

I expected better at Ambon, but probably due to a very low supply situation -

The Japanese TF retreated after combat. But, since Tavoy had been set as home port, the surviving cruisers returned to Tavoy before the Brits left, and Kumano and Suzuya were also sunk, after getting some hits on the Brit BBs. Lesson learned - set a TF home port away from any potential action, and use remain on station to defend a base.

In the meantime, BB Mutsu completed repairs at Hakodate and A6M5 Zero research advanced from Mar to Feb '43.

A single Allied xAK arrived at Merak and was attacked by Nells from Palembang. Wondering what that's about; recon by suicide?

Bases captured today: Kolaka (flipped; RES 40(0))

Bases assaulted today: Namlea

A Japanese cruiser TF at Batavia sank the lone xAK wandering nearby.

B-17s from Chungking began bombing Hong Kong, and did a good job on the repair shipyard, dropping it from 50 to 13. Two cruisers are there doing upgrades (another 10 and 14 days needed). I'm wondering if the upgrades will be discontinued if the RSY is dropped to 0? I think the upgrade start requirement for those heavy cruisers is RSY 30. Anyway, a well trained Zero squadron has been moved to Hong Kong, and other assets in China will begin a sweep and bomb campaign against Chungking. We'll see how that goes.

KI-45KAIa Nicks will become producible about a week before the normal May 1 date. A second 30(0) production site has finished and with research already at 44% and over 500 engines in inventory, 56 research points will add to the 44% in 28 (or fewer) days.

[Uncivil Engineer]

Mar 26, 1942

Bases captured today: Namlea (vacant), Sabang, and Kalidjati.

To follow up on the Nick advance, since the engine pool is over 500 (not by much, but over), Nick research advanced 4% today with two 30(0) sites. So, perhaps production will start as early as mid-April! Using 2 engines each, that will pretty much wreck the engine pool, so those (Ha-35) will be increased by at least 60 very soon.

Also, the first (of 5) Tojo research site attained 30(0) at Maebashi.

CL Helena bombarded Unmak.

Ambon was swept of Allied mines.

To try to counter the B-17s at Chungking, Zeroes at Hankow were set to sweep, followed by Betties at Hankow to bomb - unfortunately the Betties flew first and lost 6 with nothing to show for it. The Zeroes shot down 1 AVG fighter. Other Zeroes restationed to Hong Kong to intercept, but no B-17s flew this day.

All Japanese carriers arrived at Yokohama for aircraft replenishment and a couple days repair. The battleships are a day behind. Starting in April the carriers will sortie in 2 task forces, maintaining Yokohama as the home port, showing Tulagi as the destination, with a waypoint in the Aleutians. Hopefully, this will draw the Allied carriers to the South Pacific (I think at least 2 of them are already there, so to keep them there), while achieving surprise in the Aleutians. Oilers are loading in Japan to support this move, and transports are heading to the Kuriles to evacuate Dutch Harbor, if that becomes feasible.

Otherwise, nothing of significance happened to report.

These units will likely only survive another day or two, so may be done for before an evacuation attempt could start. I've been flying in supply from Amchitka, but it's not nearly enough.

Zeroes escorted Betties from Hankow to bomb Chungking, but did negligible damage. I'm not sure if the B-17s are still there or not; recon shows bombers, but that could be the Chinese junkers in training.
