Funny you should ask - the carriers just showed up.
Apr. 3-4
A couple dozen (seriously - 33 of them) Japanese paratroopers landed at unoccupied Portland Roads, in northeast Australia on the 3rd; 53 men from the same unit took the Deboyne Islands today, and on past performance will probably go for Woodlark Island tomorrow. Meanwhile, a naval base guard unit takes vacant Horn Island - this had a garrison, of course, but they were all killed by Betties. No great loss; as I mentioned, I'm not in much of a position to hold the place anyway, and it'll be good practice for whenever the time comes to get offensive up here. I'm content to let the Japanese play civil engineer if they want to - I don't have any construction engineers free locally anyway, so it saves me the bother later.
Ise and Hyuga intercepted a Dutch MTB squadron between Java and the Cocos - buggered if I know how they got out there (there are Japanese ships at Merak) or why they took off (homeport is and was Batavia) but their sacrifice apparently put off a Japanese bombardment of the place. Not a very stealthy one - they'd been loitering for a few days and most of the Dutch seaplanes, which are the only really valuable aircraft there, had already left for Diego Garcia anyway. I say most; two units stuck around in case it was just a "keep their heads down" sort of menacing - and look what they found:
Guess the drive past Java was just a distraction after all. If they're headed to Ceylon or into the Indian Ocean, they'll probably arrive before my carriers do (4-5 days); if they're headed to Sabang to pick up shipping, they might or might not. If they're just heading into the Bay of Bengal...well, who cares? Catalinas flying out of the Nicobars claim about 35-50 Japanese merchants between Sabang and Phuket at the moment, so we'll see which way they turn.
Pacific still quiet. Regular service to New Zealand has resumed - supplies and fuel were a little precarious for a while but a large convoy and half a dozen independent voyagers are a few days out.
What am I preparing to do...well, shipping for any grand offensive moves is busy moving stuff around in preparation for those rather than launching them, so mostly I'm thinking about the IO. Specifically...
Indian Ocean landings (I think it's fair to say we're definitely getting
something at this point!) will likely be the 3-5 Divs earlier assessed as 'free' if they're to be useful. Options for the Japanese are, from west to east...
- Addu and Diego Garcia; these are the obvious first steps to a big campaign as they're damaging to shipping in and out of Ceylon...but Saros tends more towards the 'throw everything not nailed down at the main target' school of amphibious operations, so I almost think taking them first would suggest he's not serious about the IO, heh.
- Trivandrum, Mangalore, Cochin; probably the more immediately disruptive of the options available; the former two just have airfield base forces on defense, while Cochin has a Dutch Rgt. Taking these would essentially make Ceylon irrelevant AND make shipping to India a pain, but there hasn't been a single Japanese submarine further north than Colombo all game - I don't think disrupting shipping is really Saros' idea of a good time.
- Ceylon; each of the promising landing points (Trinco, Jaffna, Koggala) have an Indian Bde on defense; Koggala, which is the most exposed, also has the Dutch Marine Bn. That's not going to stop 3-5 Divs, obviously. I'd remove them - shipping to do so is at Colombo and they're unlikely to acheive much - but I don't have the PPs - reinforcing them in force enough to be useful would pose similar problems. One can leave three days from now, in theory - for the moment they're all in strat move mode, so operating theory is that if I pick up the landing site early enough they can all go contest it. If multiple landings...well, we'll see. That'd deliver more opportunities for hitting shipping, though, and I know Saros is uncomfortable with operating in the teeth of Vildebeest, so I suspect there'll be one big one. Eastern Fleet HQ, the AA units and most of the support troops - anything not needed beyond day 3 of any invasion - left for the mainland a while ago, being cheap to unrestrict and unlikely to contribute much to a land campaign, which is what Ceylon would be.
- Cocanada, Vizagapatnam; the "dive into the Indian interior" option. At this point the Indian Army is capable of having something approaching a fair fight with that sort of force on the mainland, so this'd be great news. Local garrison and D-1 response forces are about a Div and a half at Madras, a cavalry Rgt at Vizag, the Dutch Rgt (110av) at Cochin, and a 'Commonwealth mixed Div' of about 500av spread out among Hyderabad, Howrah and Asansol. Day 2 gets you three Indian Divs from Bengal (perhaps 900av at this point), Americal Div from Calcutta and something resembling an Indian Armoured Div, though one mostly not actually equipped with tanks yet. And that's without drawing anything off the Burmese border!
- Diamond Harbor, Chittagong, Cox's Bazaar; the "cut off Burma" option, at least in theory. Cox's could be done by coastal shipping from Rangoon without much fuss; doesn't justify a major effort. Chittagong currently holds 1.5 Divs and 14 6" CD guns, making a direct landing likely to be messy; DH has only 60av as a garrison but 22 6" guns, and will add one Bde in two days and three more in 8-10, and obviously can draw on reinforcements very quickly.
So, based on that thinkout...probably Vizag or Ceylon, and Ceylon probably wins the argument by actually giving the Japanese something useful. Navy in theatre is 7 CL and 11 DD, mostly Dutch; the big guns are at sea with the carriers. Airforce in theatre is:
- 57 B-17
- 26 A-20/B-25
- 47 Dauntless/Swordfish
- 120 Blenheim
- 145 P-39
- 135 P-40
- 160 Hurricane
- 25 P-38
- 12 Fulmar (heh)
- Catalinas, Hudsons etc on naval search
although by necessity dispersed somewhat.
I have 30 B-17 (plus 20 in Australia that can be made available over 3-4 days) and about 260 fighters not assigned to any unit, so although it's a glass cannon it's made out of that nice glass that has rounded edges when it breaks. Carriers will add their air wings to that number if they get there in time; existing forces can punch out their opposite numbers but have limited naval strike ability. If they do I'll contest the landings, and if they don't I'll try to break the airfields as the Japanese take them.
So, to answer the question of what I'm preparing to do - well, nothing, since all the wheels are turning already. Just gotta wait and see what happens at this point.
