This is the land situation at Burma:

2nd Infantry Division assaulted Chittagong in a surprise invasion; opposition was too heavy, thus I decided to invade Cox Bazaar instead, which was successfully captured by 4th division.
Afterwards several reinforcements had been rushed (both sides). For the moment, my key objective is to open a land corridor so that 2nd ID can move out of Chittagong if needed. Later on, I will decide if it makes sense to attempt to storm Chittagong and destroy so many enemy LCUs

This is Burma; air and naval:

Naval situation is precarious, but this is after a really nasty slug fest in which I lost 2 heavy cruisers and 3 destroyers with several others having to withdraw to Singapore. I have a battleship TF coming as reinforcements, so the critical timing is the next few days in which only mini KB + a few light cruisers and DDs will need to cover important invasions.
The good news is that his losses were also severe, with several battleships and cruisers either sunk or severely damaged

The situation is as follows:

- March 27th 1942, near the end of amphibious advantage
- My main focus had been in taking over the SW Pacific islands (Suva, Noumea are taken, Pago Pago will be the last American stand).
- Burma and India had been secondary on my conquest list. Main objective here is only to push the Allies out of range of Magwe oil, to put the fighting focus up north to gain as much oil as I can before the inevitable heavy bombing campaign
- I have command of the sea; this after heavily fought battles in which, at the cost of 2 heavy cruisers and 3 destroyers lost, I sank 3 battleships and several cruisers& destroyers, wiped out Hermes air squadron and left 2 additional battleships in heavy damage, inneed of long repair.

The specific question is; what should I do with Chittagong? try capturing, bypass or leave?
as you can see, he brought pretty much everything available to guard this base.

I am debating if the benefits will out weight the costs of capturing it

some key benefits:
- Chittagong is "clear terrain"
- His LCUs are numerous, but poor quality until much later on
- Good chance to destroy scarce British devices, even more considering low rate of replacements
- Coastal hex is subject to battleship bombardment
- British air forces cannot maintain the kind of attrition losses we are both suffering over Chittagong skies; once he is depleted, I can easily start a bombing campaign

disadvantages:
- as mentioned already, lots and lots of troops
- he is on a rail junction, he can easily bring reinforcements
- he is on a rail junction, his supply flow is much better than mine,
- monsoon coming
- I will need to bring a lot more LCUs to this theater
- Lots of AA will deplete my bombers fleet

Thoughts??

I wasn't sure from your post -- is this referring to the Burma-India theater only, or the whole map? If the first, then you've pretty much destroyed or neutralized the entire RN! [X(]

Supply for your troops at Chittagong must be really difficult; I would imagine that without a good supply line you have no chance to take Chittagong. Also there is the British base at Akyab to your rear (which maybe you're going to take anyway).

How confident are you of long term air superiority? The Allies could send some American fighters to India and/or move some or all of the AVG there.

The Indomitable should still be operating and is the most dangerous threat the RN poses; and the Formidable should be joining soon enough if I remember, if it hasn't already.

All those losses in the Indian Ocean. Confirmed:
Ramillies, Resolution, Prince of Wales
Revenge and Royal Sovereign heavy damaged; maybe one or both of them sank, as I have "Oklahoma and Colorado" flagged as sunk near Akyab in the FOW ships losses list.

I saw one British carrier in the Pacific a month ago, if I have to guess, I would say he has all his carriers together
And more important, I have 3 CVLs + 1 CVE at Rangoon. I can take care of the British unless he supports them with the USN. Even then, I would have the upper hand as long as I keep the fight within LBA range


All supply at Coxs bazaar was hauled by sea, I guess I will need to keep pumping with the hope of some moving to the front. Akyab is just leftover LCUs from Burma, I will eventually deal with it, I have two more division joining the party: 14 division just entered the Malacca strait, and 48th resting at Manila.
Then I also have 38th and 21st divisions at Batavia. If resistance is weak (fingers crossed) then I can storm Chittagong in a month or so

I haven't seen any hint of US forces in India, but I would say even if they appear, I won't be worried for at least another 4 months. By then I will most likely be on the defensive anyway

Jorge_Stanbury thanks for running this DAR, I just end to read it.
That's a pity no China involved [:)]

About Chittagong: it seems a juicy target, lot of stuff here and you are doing a great job sinking his ships. I would say go for it and then retreat if you don't want to be heavily engaged in India.

We are actually fighting on China; it is just at a very slow tempo.. I will post some maps tonight.

With regards to sinking and fighting in general: he is very aggressive, in land, air and sea, which means I am inflicting quite a lot of damage, but I am also getting a bloody nose in return.

He is also good at placing submarines (or maybe I suck at ASW??); I have lost way too many tankers already: 3 "good" oilers + 2 more on shipyards repairing torpedo damage and lots of small 1,250 capacity ones. The former are irreplaceable, the later only useful until I start converting St-C in ~60 days

End of Amphibious advantage

Post by Jorge_Stanbury »

So this is where I am as of April 1st, 1942

Pacific:
Allies are still holding Pago Pago and Koumac. In the former, they have 1 USA division, 2 Marine def battalions and one base force, this against 2 Japanese division + eng + art.
I am very confident it will fall soon.

For the later: I am not sure, he might be reinforcing it (or maybe evac?). I don't have any good quality troops in New Caledonia, so we will see how this ends
-------------------------------------------------------------------------------
Submarine attack near Koumac at 113,156

Japanese Ships
SS RO-67, hits 14, on fire, heavy damage

Allied Ships
DD Hammann
AP President Polk, Shell hits 1, Torpedo hits 1, on fire, heavy damage
xAP Tjisadane
xAP Largs Bay


Northern Australia
Slowly advancing to Darwin; getting slowed down by the fact he has almost complete air superiority... still no big worry as I am really beating the crap out of this inexperienced militias.

India
Still "trapped" at Chittagong, but there are 3 more division resting before the trip up north. Once they are avaiable thing should start to flow

SRA
Manila and Batavia had been liberated; some pockets of Colonialism remains, mainly at Mindanao and Malang

Engines:

HA-35 growing by 3 to 7 engines a day
HA-33 growing by 3 to 4
HA-32 growing by 2 to 4
HA-31 declining by -1 (until I finish building another 8 Topsys II)
HA-34 growing by 2 (growth will stop with Ki-49 entering production)

heavy losses:

I am still in tears about one fast oiler, two slow oilers and one medium tanker lost [:(]
all 12 others [X(]are of the very small type.


Allied BB loses are overstated, I would guess no more than 5 battleships have been lost (all British)
Cruisers are probably not too far off

The Fleet:
Image

I am using BC to identify the fast battleship Kongo class.

With regards to damage ships:
- Zuikaku at Kure, will be back online in 4 days. then it will likely go to Rabaul
- Fuso at Singapore will need 61 days
- Yamashiro and Ise on transit to HI, the former will need around 30 days, the later around one year
- Chitose at Yohohama will need 7 days, will likely follow Zuikaku
- CAs: Suzuya at Yokohama 14 days, Haguro and Ashigara at Rabaul& Singapore respectively 7 days. CA Kako, CLs Kis and Abukuma at Suva will require a month to get emergency repairs prior to moving to HI. CL Kuma at Singapore 22 days.

Ships sunk:
- Hyuga due to TF decision to react to Singapore guns [:-]
- Atago, Takao and on an epic battle against British BBs in the Indian Ocean.
- Isuzu, Katori, Kashima and Kashi on amphibious operations, defending against enemy raiding forces or taking the brunt of coastal gun fire
- Oi fighting the USN in the Pacific
- Destroyers: 6 on Singapore react fiasco, 3 due to mines at Bataan/ Manila, 3 fighting in the Indian Ocean
- Torpedo boats: 1 defending a convoy

Enemy losses are of course much harder to assess:

I have excluded (in red) those that are probably too good to be true:
- I believe all USN BBs survived, with maybe 4 still under repair; but for some reason they keep coming on the sunk list.
- I have also excluded submarine torpedo hits, because it is really difficult to sink anything bigger than a destroyer with only one hit. And in most scenarios it happened near an important base (Pearl or WC)

I am playing PDU- OFF
so main focus of R&D is on the Zero line for IJN and Oscar/ Frank for IJA

I just noticed the very useless KI-54c Hickory... this will be replaced for another 30 KI-61a Tony
EDIT: no, actually I will change it for another D4Y1

I plan to keep the two A6M3 factories doing research (next in line would be A6M3a) and convert the existing B5N1 production into A6M3, this once A6M3 is available and I run out of Hikari engines (should happen in a month).

RE: Pago Pago fell

Where is the army?

Pago Pago fell suddenly, so it will take me some time to redeploy the 2 victorious divisions. I will likely move them to Burma; this after Koumac is secured (guarded by one Australian brigade + support)

Java's 2 divisions will finish Malang's redoubt, then rest/ recover and then they will also move to Burma

16th Division in very bad shape from Manila fighting, but should be good enough to finish Malaybalay redoubt
