Yeah, 5 Ind. Mixed Brigades and 5 Divisions is nothing to laugh at, granted, but there's a two month period in early 1944 when I've 8 (!!!) divisions and 9 Ind. Mixed Brigades arriving! What's more, their TOE's are better. Some of the stuff I've bought out from China is little more than a three hundred infantry squads with some 75mm guns. Sadly they're not all unrestricted, so I'll need a good PP stockpile.

Not that China Exp. Army being freed isn't an absolute blessing. I've an excellent core of troops with some absurd EXP levels on the Marianas, on Sumatra and Java and I'll probably never need to reinforce Burma.

What I need the reinforcement units for is to start to fill in the gaps. There's basically there's not a single combat unit on New Guinea north of Lae at present. There's nothing on Babeldoab, or Yap or Ulithi, nor is there anything at Ambon, Kendrai or Makassar.

Once those areas have a decent garrison, I'll need even more troops to start filling out the "last stand line": Luzon, the Bonins, Okinawa and Formosa.

My hope is to draw Lokasenna into a long, drawn out battle on my own turf. I really don't want to lose islands to the first Allied attack: I want the first wave to fail to take the island and get a bloody nose, and I want the following waves to take a beating to CD guns, mines, subs and air strikes.

I've made a comment to Lokasenna to the effect that he needs to take the night-vision goggles off the bomber gunners and give them to his fighter pilots.

Night bombing has been a big part of this game, and something feels wrong. The only real factor that seems to influence the results is the weather: fighters on CAP, flak, barrage balloons ect don't do much even when combined, so it seems a lottery...

The pressure builds...

North Pacific

The remainder of the 20th Division is bought out from Korea and is a few days out from being landed on Onnekotan-jima.
This will give us two divisions on the two northern-most islands in the Kuriles - if the Allies are looking for a easy landing in the Kuriles, they'll need to land closer to the big airbases on Hokkaido.

Central Pacific

Allied marines land at Onotoa (adjacent to Tabiteuea), and take the base, destroying the 10 Emily search planes operating at the base. While the loss of a months production of Emily's hurts, a recently arrived squadron of Judy recon planes should be able to step in and cover the gap till the unit is bought back.

We'll bomb the Americans off off Onotoa and re-take the base by paratroop attack, as is the custom.

DEI/SWPAC

For ease of reporting, I'll combine these two theaters.

On April 4th, the Allies drop the 503rd Parachute Regiment on to Merauke and follow that up on the 5th with a USN base force unloaded by LST's. The Japanese defenders are a SNLF behind level two forts, and they're able to shake off the first Allied attacks.

The Allies bomb Merauke with everything they have; the Japanese defenders take a beating from large numbers of Allied bombers flying from Austrailia. I respond in kind, with Helen's from Hansa Bay doing what they can to inflict damage on the Allies troops, to limited success.

At sea, however, the advantage lies firmly with the Japanese. It takes me till April 7th to furnish a naval presence west of Horn Island : a raiding force built around the light crusier Tama approaches the Torres Straits from Timor. It's mission was to smash a path through the Torres Straits, sink what shipping they could find and head for Port Moresby and the protective sheild of Japanese airbases on New Guinea.

Air losses screen shows only 2 Kingfishers lost on the ground, so we've at least sunk one Allied battleship and another one isn't likely to make it home.

The Allies have some success of their own in the air. Taberfane is shut down by a massed 4E raid, leaving a whole host of A6M5's trapped on the runway. The light crusier Kinu and the destroyer Tsuta are both sunk in the harbour as well after the Kinu took a torpedo escorting an FT task force. This is a concern, as it's a airbase in a perfect position to support operations around Merauke.

P-40K's also have a go at Tama and her escorting destroyers, strafing and droping bombs from 100ft. They score a few hits, knocking one destroyer down to 24 knots, but only causing minor system damage on the rest of the ships.


The situation in the Horn Island area on April 9th


China-Burma-India

Quiet, no events worth reporting.


Although the Allies slow battleships are far outclassed by the modern fast battleships, sinking them is still a victory.

Status: offline 		I have a vague plan developing...

The Situation

With Merauke changing hands, it puts the Allies in a strong position in the area around Horn Island. The loss of Merauke enables the Allies freedom of movement in the Gulf of Carpentaria, which in turn opens the possibility of the Allies building a chain of bases to enable supplies to reach Darwin.

The loss of Merauke, however, also present an oppertunity to fight the Allies on advantagous terms. The Allies will be hampered by the geography of the region: the Torres Straits means that any Allied naval forces will need to run the gauntlet of Japanese aircraft on New Guinea and brave the Japanese submarines that will choke the strait and Allied air power is limited to the bases on the Austrailian mainland.

The Japanese, however, will have the advantage of being close to their fuel centers in the DEI as well as being able to operate within range of several large airbases on both flanks of Merauke.

In essence, I can't allow the Allies to mount a campaign through the DEI to re-open lines to Darwin this early in the game.

The Plan

Excuse my paint skills.



Blue: The Mini-KB will move to the hex marked to cover the landings. I'm reluctant to go any further south, as there's little sea-room as it is for large scale operations.
Red: The invasion and bombardment force.
Green: The covering forces. Destroyers, as well as light and heavy crusiers. If the Allies want to interupt the landings, they'll need to fight their way past a lot of Japanese ships.
White: Pre-landing LBA bombing campaign from Hansa Bay to keep the airbase shut and troops disrupted.

The main logistical base for this operation will be Soerabaja, with a forward base at Kendrai.

The plan will be to land a full IJA division, plus a brigade and some naval support in the first wave to retake the base. The division will then reload while the second wave lands engineers and aviation support to allow Merauke to fly CAP of it's own.

The Naval Forces

Mini-KB
CV Junyo, CV Hiyo, CVL Ryuho, CVE Taiuo, CVE Unyo and CVE Hosho with 7 destroyers as escorts.

The Bombardment Force
BB Nagato, BB Mutsu, BB Fuso with 4 destroyers as escorts.

The Invasion Force
1st Wave: CL Kiso, CL Kuma, 4 destroyers, amphibious ships and ASW escorts.
2nd Wave: CL Oi, ASW escorts and amphibious ships.

The Battleship Force
BB Ise, BB Hyuga with 4 destroyers as escorts.

The First Cover Force
CA Tako, CA Atago, CA Chokai with 4 destroyers as escorts.

The Second Cover Force
CA Furutaka, CA Kako, with 3 destroyers as escorts.

The Light Screen Force
CL Nagara, CL Isuzu, CL Natori with 3 destroyers as escorts.

The Ground Forces

The first wave
IJA 2nd Division (on Java), 463 AV.
21st Ind. Mixed Brigade (on Christmas Island IO), 137 AV
7th Shipping Engineer Regiment (at Manila), 0 AV.

The second wave
14th & 15th Naval Construction Battalions
32nd JNAF AF Unit
97th JAAF AF BN

The operation will commence when the first wave has 75% prep. The three units are all sitting between 25-33% prep, so the preliminary date for the operation is May 8th

Concerns

- The extent to which the Allies reinforce. If the Allies get a large number of troops ashore in the next few weeks, then we've a problem
- I'm mildly concerned about the Allied carriers making an appearence, but the region isn't exactly suited to carrier operations with all the chokepoints and lack of searoom.
- I've never done a invasion as Japan in 1943, so I've utterly no idea what I'm doing.


I'd love some critique.

Lok likes to throw away his battleships doesn't he?

Hmm, I like the idea of 50% prep. I can be at that in a little over two weeks. I'll be one week or so getting shipping into position anyways, and the sooner I get things moving the better.

I'll trade the extra disablements on landing than giving the Allies another few weeks to throw more troops into Merauke.

He's pretty flush with them at present. My PH raid didn't sink any, so even with my success in sinking them so far, I'm still behind the historic numbers.

Do you think the attack is really worth it?

Tatically, no. Strategically, I think so. If he gets Meruake, he gets Darwin. He gets Darwin, he's got a steping stone to the DEI, and he'll have a fairly secure line of bases to cover supply convoys into Darwin.

On the wider stage, I don't want Lokasenna to be able to mount an island hopping campaign through the DEI. CentPac or SWPAC, yes. The DEI is just too close to the oil.

You don't see the half to 2/3 of the missions ordered that don't take off or RTB before you defend against them.

Gove & Wessel Island - After Merauke became Allies, I took these two islands easily and this allowed me to use LSTs to resupply my Allied Army laying siege to Darwin by landing massive supplies over the beach. Once that happened, Darwin was mine. Both bases can have 35k in troops. Gove can reach size 8 AF while Wessel can be size 7. Don't forget the Allies can build up bases very quickly.

Skimming back over the combat reports, we're getting about 10 mins warning of a raid in good weather. The problem is that the fighters on night CAP do very little to disrupt the bombing.

The 16th Army HQ has now been added to the first wave. I can't get a Command HQ within range, so we'll need to hope for that 10% boost.

Gove & Wessel Island are surely Lokasenna's next target, and he's already taken Gove with a fragment of an Austrailian brigade. I'll need to push him off Gove with a paratrooper attack, and there's a SNLF on the way to occupy Wessel Island.

I may try to build these bases up to make getting through to Darwin that little bit more difficult, though it would be a hard task, seeing as those bases are well within escort range of Allied airbases in North-Eastern Oz.

North Pacific

The 20th Division is created on Onnekotan-jima. As an added bonus, the division upgrades to IJA 1943 Infantry squads.

Central Pacific

IJA paratroopers recapture Nanumea. The Americans have departed again by submarine.

Despite the Allies showing a keen interest farther to the south, I'm keeping a significant air presence here. Looking at the strategic map, I'm getting the "left jab, right hook" impression from the red and green dots.

South-West Pacific/DEI

We're getting things arranged for the counter-punch. Tenders, fuel and supply are all en-route to Kendrai to enable that base to operate as a forward fleet base.

The war in the air continues, with Nell's and a strong escort punching through Allied CAP offshore of Portland Roads to put a torpedo into an APD.

Reinforcements for Horn Island or Merauke? In any case, I'm moving some IJA dive bombers into position to try to see if they can mount some night-time attacks, just to keep the Allies honest.

Then there's this interesting strike on what I assume to be Allied CVE's:

Afternoon Air attack on TF, near Cooktown at 96,138

All are CVE fighter squadrons. So we've an Allied carrier presence off North-Eastern Oz as well.

There's also a little good fortune in the naval war as well, with IJN submarines in the Torres Straits having some good luck on the 10th:

Allied submarines are also on the prowl around Milne Bay, where there was a shooting gallery set up for the Tama and her escorts. Thankfully, they all miss. Sadly, though, I scuttle the Akikaze, the fires on her were burning out of control.

Off Malacca, however, a bold Allied sub gives out a good beating after a PB forces it to the surface.

Allied Ships

Sinking sounds are heard, so hopefully we can scratch one Allied submarine off the list!

The SNLF at Merauke still holds on, despite the Allies owning the base. They've no supplies and little AV, but they're there. The Allied paratrooper unit seems to be sitting at around 15 AV, so I'm working on the possibility of a paratrooper counter-invasion. To that end, two IJA paratrooper regiments are being flown in to Hansa Bay to see if we can't get Merauke back on the cheap.

I'm also working on shoring up the bases that are in the Allied line of advance. I retook Darwin with a paratrooper fragment, and I intend to land a SNLF and some engineers to try to get the airbase there back up and running and moving some aviation support from Timor to Darwin to slow the Allied tempo of operations. If there's a need, I can shift a good division from Sumatra to hold Darwin.

There's an Naval Guard unit destined for Wessel Island as well, and I'm going to recon Gove to see if I can't recapture that base as well. If I can, they're prime candidates to be built up to become forward fighter bases.

In short, if I'm going to go on the offensive to recapture Merauke, I'll be making sure I've got my rear and flanks secure as well.

China-Burma-India

Our supply problems in Burma are at an end, and efforts to build Magwe up to a size 7 airbase (for the barrage balloons) has resumed. This is needed, as Allied bombers make another night-time raid on the oil at Magwe, knocking a few more points off of it.


The strategic map. China is very pretty when covered with red dots, but I don't like the single green dot on New Guinea!

North Pacific

Nothing is stirring up here.

I've debated moving the Yamato's to join in the counter-attack against Merauke. The only thing that's making me pause is the fuel cost and the difficulty in replacing these two ships. While moving them to the DEI makes them less of a logistical drain, I'll be hard pressed to find replacement ships to give the IJN even a token presence in the North Pacific.

I'll wait and see.

Central Pacific

Other than some sub-chasers going after the Gato outside Truk, things here are quiet also.

I'll need to move a bunch more sub-chasers to Truk and other CentPac bases, as I really want to leave the E-class ships for duties on the frontline. Granted, the sub-chasers very rarely sink anything, but they do an exceptional job of making the Allied submarines waste torpedos on dinky 1 VP targes.

South-West Pacific

The "Happy Time" for the IJN submarine fleet continues. They've already put a damaged battleship under, motiviating them to new feats of valour!

This is pretty solid proof that there's some sort of Allied carrier presence in the South-West Pacific. As to where the fleet carriers are - it's anyone's guess.

Above the waves, four Fletcher-class destroyers head for Milne Bay, sinking two converted E-class escorts that were on ASW duty off the eastern tip of Papua. The Allied ships are gone before dawn, so there's no revenge strike from Buna or Rabual.

In the air, the usual night time raids from 2000ft fly against Lunga. As usual, the Nicks on night CAP are up in force and lose a few planes with little to show for it, but thankfully the weather is "severe storms", so there's minimal damage to the airbase.

Come dawn, the IJN fighter groups on New Guinea pull off an impressive feat, co-ordinating a sweep of 89 (!!!) A5M6 to attack Horn Island. Sadly, the sweep finds nothing but empty skies - the Allies don't have any CAP up. The IJN air groups will stand down, and we'll try again once the fatigue has worn off.

On the ground, the Allies at last wipe out the last defenders of Merauke as the Yokosuka 4th SNLF ceases to exist as a fighting force. However, all is not lost, as the two IJA paratrooper regiments at Hansa Bay are dropping on Merauke tomorrow in an attempt to steal the base back before the Allies can reinforce the base force and the 503rd Parachute Regiment.

DEI

Soerabaja, up until now a backwater repair yard for submarines and escort ships, is now the jumping off point for the counter-attack against Merauke. The amphibious force and the LCU's should be ready to go within ten to fifteen days. Most of the combat ships are already in position, with the IJN slow battleships gathered east of Timor. If possible, they'll try to make a bombardment run in the next day or two to try to soften up Merauke for the paratrooper assault.

Elsewhere, shipping to move units to occupy Darwin and Wessel Island are moving in to position. I'm very eager to re-occupy Darwin with a token garrison, but even more urgent is the need to garrison Wessel Island and to recapture Gove.

China-Burma-India

All is quiet on the Burma-India frontier.

Some of the Southern Army heavy artillery park is sitting at Rangoon waiting for shipment to the Marianas. I like the notion of having some heavy IJA weapons to back up the IJA infantry units that are quite light on artillery. Most of them are destined for the islands that don't have any serious CD defences - Tinian, Rota and Pagan.

Work to bring Magwe up to a size 7 airbase is progressing well. I'm annoyed that I've not made an effort to do it before now, as having barrage balloons would probably ensure that any night bombing against is ineffective and costly. Then again, I thought that about bases elsewhere and it turned out I was wrong.

Industry

Home Island Stockpiles:

Supply - 3,040,115 - Supply over 3 million in 1943! I may even be able to have nearer to 4 million supply by the time 1944 rolls around!
Fuel - 2,445,296
Resources - 10,505,923
Oil - 1,324,506

In short, resource stockpiles in Japan are looking pretty good.

Pools

HI Total - 1,363,458 - Not great, but we seem to be on track for our goal of banking 1M HI points per year. I may start turning off some Nav and Merch Shipyards.
Armaments - 199,037 - Excellent, we'll be needing all of it in a few months, for the torrent of arriving IJA units.
Vehicles - 23,215 - I may halve production, seeing as there's only a half dozen armoured units set to arrive over the next year, and then resume production in 1945 in preparation for the rush of late-war reinforcements.


The fuel crisis that was developing in China has been solved by diverting a couple of shipments destined for the Home Islands to Shanghai.

Use them where you can hope for a surface engagement, but not where there is Allied air superiority. As an Allied player, they will be nothing but targets a year from now when the Allies have Fletchers everywhere.

Fletchers do 38 knots and can move 11 hexes. I've used them on Full Speed "hit & run" attacks. 8 of them in a SC TF can do some damage.

Nah, I think I'll keep the Yamato's on ice in Ominato at present. They won't burn any fuel sitting pierside, and if there's ever an Allied forray into the Kuriles, they'll be on hand. What's better is that in the event they take serious damage, I won't have to nurse a wounded battleship across half the map.

North Pacific

ZZZzzzZZZ

Central Pacific

Wake reaches level 5 forts, and with 120 AV to defend the island, I feel quite comfortable about this exposed outpost. Marcus and Eniwetok are also looking very strong bastions, with both having 170 AV behind level 4 forts. This should force the Allies to go through the full "atoll routine" of naval and air bombardment prior to any landing, or risk an assault getting cut up on the forced shock attack against a strong defence.

There's going to be another overhaul of garrisons in this sector in a month or two, as the main garrison unit on Mili is set to be reinforced to a division in 40 days and Mili isn't worth a division to me. The good news is that there's a SNLF and a Naval Guard set to arrive around the same time, so there will only be a moderate reduction of AV on Mili.

I'll be swapping units out on Tabiteuea as well. I'll pull 200 of the 400 AV off the island to redeploy to a base further in the rear (likely Ponape) and replace it with 100 AV's worth of smaller units. 300 AV behind level 5 forts seems a "just right" defence for Tabiteuea.

South-West Pacific

There's going to be garrison swapping around here as well. The 12th Ind. Mixed Brigade at Tassafaronga can now combine with reinforcements to become a division, but to leave it on Guadalcanal would be over-kill as there's a 340 AV Division sitting at Lunga. Instead, the 12th IMB is going to garrison Port Moresby, which will free up the 9th IMB as well as the Guards Mixed Brigade (which is due to become the 1st Guards Division by mid May). The 9th IMB will garrison Tassafaronga while I'll likely send the 1st Guards Division to Babeldoab.

In terms of actual fighting, the Allies mount another nusiance night-time raid against Hansa Bay with their 4E's. The moderate rain does more to spoil their aim than the Japanese fighters on night CAP, and only a half-dozen planes are lost on the ground and the damage to the airbase is repaired by dawn.

Some Fletcher's also shell Port Moresby, but there's not much here bar some Jakes.

The attempt to recapture Merauke by paratrooper has been foiled by the Allies flying in part of an Austrailian brigade. The IJA paratroopers still hang on, but the Allies have nearly twice their AV.

The Allied CVE force is sighted just off Brisbane, no doubt deciding that the narrow waters of the Torres Straits was being made too dangerous by IJN submarines.

The crusier Tama and her escorting destroyers managed to reach Rabaul without any trouble and recived a hero's welcome for their exploits in running the Torres Straits. The ships are headed to Truk to have their system damage knocked off before they're redeployed, likely to the Marshall Islands.

DEI

Combat shipping is forming up at Kendrai and the invasion shipping is gathering at Soerabaja, while the troops destined for Wessel and Darwin are loading up at Roti and Saumlaki.

I've sent four Shiratsuyu-class destroyers on a bombardment run of Merauke, just to keep the airbase suppressed. The slow IJN battleships are hovering off Dili, and a surface combat force built around the two Agano-class light crusiers is going to hang around near Taberfane. Currently, the Gulf of Carpentaria is devoid of Allied shipping, but if any ships do try to make a run for Merauke or to make a move on Gove or Wessel Island I want to make sure that they're met by a strong IJN presence.

China-Burma-India

There's a few garrison units due to arrive in China in the next month, so hopefully I can see about getting some more units freed up. There's a nice 210 AV IMB sitting in Wuchang that would look lovely on Yap or Peliliu.

All's quiet in Burma, our supply problems seem to be history.

There's 92 ships in Colombo on Ceylon and only 52 fighters reported defending the base. I'm more interested in the fact that some AP ships are reported. I'll recon the rest of Ceylon and Madras as well for good measure.

This has me thinking: the Burma panhandle is strongly held, but Victora Point is virtually undefended so I'm moving the Imperial Guards Division from Burma to Thailand to rail down to Victoria Point. The Andaman's are also pretty poorly held, but I've got the INA units arriving in ~80 days, so they'll do nicely as expendable garrison forces for the Andamans.


The light cruiser Tama, which along with it's escorting destroyers have became the focus of Japanese propaganda in the wake of their dash through the Torres Straits.

A slow few turns, as real life gets in the way for both of us.

North Pacific

Bore in the Pacific up here...

Central Pacific

A task force of 4 Fletchers mounts a night-time bombardment raid on Tabiteuea, sinking two Japanese torpedo boats and damaging the airbase slightly. I had a fragment of the Wake CD unit here, which fired off a few shots but failed to score any hits. I'm recombining the fragments of the Wake CD unit on Tabiteuea, as the 20cm guns were left on Wake in case of another Allied raid, but that's looking unlikely.

This is the first real Allied surface force we've seen for several months, and I'm still not sure if it's an opertunistic raid from some destroyers or a probe in preparation for a major move in this area.

Nevertheless, I feel comfortable enough to risk sending the KB back to the Home Islands for their April '43 upgrades. I really need the extra radar sets on the ships, and there's no easy targets that the USN can hit while the KB is out for repairs.

South-West Pacific

The Allies have reinforced Horn Island to a considerable extent, with 18k men and 200 AFV's and guns.
The only real harrassment has been from IJN submarines, which have been dueling with USN destroyers for the past few turns, but have failed to hit the fast Fletchers.

In the air, things have been uneventful, as I want my air groups in prime condition for the upcoming bid to recapture Merauke. The Allies have flown fighters in to Merauke, but the airbase is at 30% damage, so the IJAAF is mounting a big raid from Hansa Bay to close the airbase prior to the commencement of operations against Merauke.

DEI

The invasion shipping is gathered in Soerabaja. The Mini-KB is stuck in Singapore for the next five turns while Junyo and Hiyo finish their April '43 upgrades (well worth the wait, as it gives the MKB two carriers with radar), and once they're back in commission, they'll move to Soerabaja in preparation to cover the counter-invasion forces.

Darwin is re-occupied by the Allies, with the 3rd Motor Brigade marching back into the hex. IJA bombers from Timor sortie against the Austrailian unit, and it looks like they're headed back south. Hopefully, we'll be able to re-take Darwin by paratrooper assault and land a SNLF to occupy Darwin. Troops should also be in a position to land on Gobe Island by April 18th.

The attempt to bombard Merauke has been foiled by a single Allied destroyer:

Day Time Surface Combat, near Merauke at 86,123, Range 19,000 Yards

Japanese Ships
DD Shiratsuyu
DD Shigure
DD Murasame
DD Samidare, Shell hits 1

Allied Ships
DD Norman, Shell hits 1


Despite minimal damage to both parties, the IJN destroyers managed to waste nearly all of their torpedos and a fair chunk of their main gun ammo, so they're headed back to Kendrai to refuel and rearm.

The Agano/Noshiro surface combat force is also moving into the area to cover the Gove Island landing, and I'll try to pull off a fast bombardment run with them as well in the next few days if they don't end up in a fight.

On the ground, the invasion force is nearly ready. The 2nd Division is at 50% prep, and the support units range between 30-40% prep. I'd rather take the extra disablement losses than have the Allies put reinforcements ashore in the time it takes to reach 100% prep.

D-Day for the counter-invasion is set for April 28th. I have 11 turns to make ready.

China-Burma-India

Calm and quiet.


IJN SNLF troops destined for Darwin. The Japanese empire had abanonded Darwin, and now it was returning to place a garrison.

North Pacific

There's a great deal of Sig Int hits on Allied bases in the Aleutians, and recon planes over Attu have spotted some light crusiers. I'm not hugely concerned, as we're pretty prepared for things in the Kuriles.

Central Pacific

The KB reaches Yokohama and the carriers start their upgrades - we need the radar on these ships.

The only real action in this theater is that the Allies have another go at bombarding Tabiteuea on April 20th, and this time, the CD guns are awake and ready for them.

TF 167 encounters mine field at Tabiteuea (137,134)

Japanese ground losses:
108 casualties reported
Squads: 0 destroyed, 3 disabled
Non Combat: 1 destroyed, 11 disabled
Engineers: 0 destroyed, 0 disabled

There's no damage to the airbase, but the Fletcher's are gone before daylight and the only losses are a couple of mini-subs that decided to take a shot at the Allied destroyers.

There's also a bombardment of Wake by three destroyers, but again there's no damage done.

These DD raids are pretty obviously probing attacks into the Marshals/Gilberts area, and Lokasenna's already got some good information from them (ie Wake CD guns on Tabiteuea) and there's regular long-range recon flights into the area, so he'll be able to get some idea of my dispositions.

So that's another area I'll need to be concerned about. Thankfully, I've a good reserve of IJN DB and TB squadrons already deployed in CentPac, and a vast bulk of fighters can be transfered in within a turn or two.

South-West Pacific

The ocean around the Torres Straits is becoming more and more dangerous for Allied shipping. Here's a selection of anti-shipping attacks against Allied task forces that occured over the past seven turns:


Allied Ships
xAKL Corrimal, Torpedo hits 2, and is sunk
xAKL Lorinna
xAKL Surigao, Torpedo hits 2, and is sunk
xAKL Corregidor, Torpedo hits 1, and is sunk
xAKL Benkalis, Torpedo hits 1, and is sunk

Allied Ships
DD Waller
DD Nicholas, Torpedo hits 1, and is sunk
DD Cony

Allied Ships
DD Cony
DD Waller, Bomb hits 2, on fire

Allied Ships Nell's sortied against these ships on the 24th, looks like a bombardment TF for Port Moresby. No hits.
CA Pensacola
CL Nashville
CL Honolulu

Allied Ships Lily dive-bombers also joined in, again no hits. I'd have loved to have sunk or damaged a few crusiers.
CA Quincy
CL Nashville
CL Honolulu
CL St. Louis


This is scarce a drop in the ocean, but I'll happily fight a war of attrition in trading airframes for ships, even if only to make Lokasenna's progress here that little bit more difficult.

I've been moving more and more IJN submarines into the region, but I've not really been having much luck. At this point in the war, Allied ASW is so good that my subs are either being sunk out-right or crippled in the event that they dare to fire off some torpedos. I'm relegating most of my subs to picket duty off the Austrailian coast or between New Caledonia and Fiji.

The Allies aren't completely passive though, as they mount their usual night bombing raids on my major airbases at 2000ft. It's the usual story: a one-sided slaughter of Japanese airframes on the ground or on night CAP, and the Allies escaping with minimal losses. I've made some grumbles about a possible HR to Lokasenna reagrding night bombing, but I don't think it's fair to insist until I've got dedicated night fighters in strength.


Situation in the Torres Straits as of April 17th.


DEI

Two misfortunes.

The attempt to land a Naval Guard at Gove is foiled by an Allied destroyer force on the 18th of April. The covering force of two Agano-class crusiers plus destroyers fails to intercept, leaving the Allies a free hand to wreck the troop convoy over two battles and sinks the lot of them.

The following day, April 19th, the Agano's are devoid of a convoy to protect, so I send the covering force to bombard Merauke along with the heavy crusier Aoba in some small measure of revenge. However, I make the old mistake of leaving the TF on "Remain on station". The bombardments go well, but daybreak brings the Allied revenge:

The magainze explosion on the Noshiro is very unfortunate, as the rest of the ships are in fairly good condition - all things considered. The Agano has SYS damage in the mid 40's, but she managed to make Bolea, and no other ships were lost, but it's a sad few days for the IJN.

In the air over Merauke, the F4U makes it's combat debut, abiet in small numbers. This new airframe has some inital success, shooting down 15 or so Helen's headed to bomb the airbase that failed to link up with their escort, but massed sweeps from Zero's and Oscar's quickly forces Lokasenna to withdraw the fighters from such an exposed position.

On the ground, I make the mistake of trusting AV values too much, thinking that my 50 AV of IJA paratroopers might be able to get a good roll against 80 AV of US paratrooper and Austrailian infantry squads. The Allies are able to conduct a massive reinforcement by air, leaving the actual AV numbers heavily stacked against the Japanese paratroopers.

Needless to say, the result is a slaughter and my paratrooper units are promptly wiped out, though fragments of both units survived and are reinforcing at Hansa Bay.

Japanese Deliberate attack

Attacking force 1448 troops, 6 guns, 0 vehicles, Assault Value = 52

Defending force 6577 troops, 84 guns, 65 vehicles, Assault Value = 174 Up from ~80 AV

Japanese adjusted assault: 12

Allied adjusted defense: 137

Japanese assault odds: 1 to 11 (fort level 0)

Combat modifiers
Defender: terrain(+), preparation(-), fatigue(-), experience(-)
Attacker: supply(-)

Japanese ground losses:
282 casualties reported
Squads: 5 destroyed, 44 disabled
Non Combat: 0 destroyed, 7 disabled
Engineers: 0 destroyed, 0 disabled

Allied ground losses:
54 casualties reported
Squads: 0 destroyed, 6 disabled
Non Combat: 0 destroyed, 0 disabled
Engineers: 0 destroyed, 2 disabled

Assaulting units:
1st Raiding Regiment
2nd Raiding Regiment

Defending units:
503rd Parachute Regiment
16th Australian Bde /2
224th USN Base Force

With 170 odd Allied AV sitting at Merauke, time is of the essence to recapture the base.

China-Burma-India

A few garrison units arrive in China, allowing me to buy out an Ind. Mixed Brigade of 210 AV. They're destined for Mili, to replace another Ind. Mixed Brigade that's due to upgrade to a division next month.

Elsewhere, all is quiet.


Allied attack bombers roars over a Japanese destroyer off Merauke. The nimble destroyers were able to avoid serious damage from bomb hits, the less manuverable crusiers were not so fortunate.

Well, we've pulled the trigger, and here's what we're going in with.

The Order of Battle

"Mini-KB"
CV Junyo
CV Hiyo
CVL Ryuho
CVE Hosho
CVE Taiyo
CVE Unyo
CS Mizuho
CS Nisshin
7 Destroyers

"A" Force - Heavy Surface combat TF
BB Fuso
BB Ise
BB Hyugo
3 Destroyers

"B" Force - Bombardment force
BB Nagato
BB Mutsu
2 Destroyers

"C" Force - Heavy crusier force
CA Tako
CA Atago
CA Chokai
4 Destroyers

"S" Force - Invasion Screening TF
CA Furutaka
CA Kako
CL Nagara
CL Isuzu
5 Destroyers

"L" Force - Light surface combat TF
CL Natori
CL Kuma
CL Kiso
4 Destroyers

"I" Force - Invasion Task Force
CL Oi
2 Destoryers
3 E-class escorts
4 AMC ships
1 APD
2 LSD ships
15 AK/AK-t/xAP class ships
Carrying: 21st Division and 7th Engineering Regiment

"R" Force - Reserve Invasion Force
4 E-class escorts
13 AK class ships
Carrying: 14th & 15th Naval Engineer Regiments, 32nd JNAF Battalion

The Plan

All ships will gather in the hex north-west of Taberfane (Point Carillon - marked in white) to regroup before moving south as a single body. The Mini-KB will depart to 3 hexes north-west of Merauke (Point Duquesne - marked in green) and there provide carrier cover to Japanese shipping. The various surface combat forces will take up positions west of Merauke, in preparation of fighting Allied surface ships as the move west through the Torres Straits.



This will be the first big invasion that I've tried to run as Japan post-1942, so I'm looking forward to seeing what the outcome will be.

I'm way, waay behind, so I'll try to paint the picture in as many broad strokes as possible.

April 29th

The operation swung into action on April 29th (the Allies had warning for one or possibly two days beforehand) with massed A6M5 sweeps over Horn Island. The Allies aren't home, and the sweeps find empty skies.

Some Beaufighters sortie from bases on the mainland against one of the invasion task forces, but there's a strong LRCAP of thirty A6M5's covering the ships, and the Beaufighters are severely mauled without reaching the ships. Six B-25D1's have a go at the Mini-KB, escorted by 17 Lightnings, and the break through despite the healthy CAP, so I need to endure the sight of 4 B-25D1's mounting a strafing run on the carriers Junyo and Unyo. They miss, but it's a worrysome development. A smaller strike of 6 B-25s goes after the amphib ships, and again they miss. It's disconcerting to see these small strikes get through, even if they don't do any actual damage.

A quartet of American destroyers are targeted by the Mini-KB's strike groups, which put two bombs into the destroyer Radford in the AM phase and three bombs into the Downes in the afternoon.

April 30th

The two task forces that were screening the invasion force are detached to hunt down the four American destroyers. The destroyers Ellet and Perkins manage to escape from an IJN crusier force with trival damage, but the Radford blunders into three Fuso-class battleships and is promptly sent under.

Our fighters on New Guinea go after Portland Roads, a real hornets nest of Allied fighters. We do pretty poorly against Cosairs and Spitfires, as well as older Warhawks, but the whole purpose was to apply pressure on the Torres Straits from two directions.

In the Arafura Sea, the Allied 4E's are unleashed upon the IJN. Despite the almost complete absence of escorts, the bombers are pretty easily able to fly right through the fighters on CAP over the ships and line up on target:

Japanese aircraft
A6M3a Zero x 4
A6M5 Zero x 41

Allied aircraft
B-17E Fortress x 10
B-24D Liberator x 13
B-24D1 Liberator x 4
F4F-4 Wildcat x 8
PB4Y-1 Liberator x 6

Japanese aircraft losses
A6M5 Zero: 1 destroyed

Allied aircraft losses
B-17E Fortress: 1 damaged
B-24D Liberator: 2 damaged
B-24D Liberator: 1 destroyed by flak
F4F-4 Wildcat: 2 destroyed
PB4Y-1 Liberator: 1 destroyed by flak

Japanese Ships
xAP Kongo Maru
AK Sasako Maru
AMC Asaka Maru
AMC Bankok Maru
AMC Gokoku Maru
AK Kansai Maru
LSD Shinshu Maru, Bomb hits 1
CL Oi
LSD Akitsu Maru

This was one of the bigger attacks, though there were perhaps a dozen or so smaller attacks all over the Arafura Sea. This must have left the Mini-KB's CAP scattered across hundreds of miles, because this raid came in and the Mini-KB decided that it was just too cool for CAP:

Morning Air attack on TF, near Merauke at 86,123

Weather in hex: Moderate rain

Raid detected at 33 NM, estimated altitude 6,000 feet.
Estimated time to target is 11 minutes

Japanese aircraft
E13A1 Jake x 1 - Where is the CAP? Where is it? Where?!

Allied aircraft
B-24D1 Liberator x 6

No Japanese losses

Allied aircraft losses
B-24D1 Liberator: 2 damaged

Japanese Ships
CVE Unyo, Bomb hits 1, on fire
CV Hiyo

The damage is trival, but the Mini-KB's flat-tops are in American bombsights over another four raids, leaving me very, very worried. Three of the amphib ships take a bomb each and the destroyer Fumizuki eats a bomb, but there's not any serious damage, but this turn highlights how woefully little airpower I have and how absurdly thin I have it spread.

I scrub the operation. The amphibs are a hex out from Merauke, but every ship is to turn tail and run for the saftey of the DEI.

May 1st

The crusiers Atago, Takao and Chokai find themselves in trouble. They're exeptionally exposed just north of Mornington Island, their destroyers are out of fuel, the crusiers are low on fuel and the Mini-KB is too far away to provide support. Allied ships are starting to close in, and Allied CV's have been reported around the Townsville area.

Allied bombers have a go at the exposed Japanese ships during the day, but they only manage to land a few bomb hits on the destroyers and miss the crusiers.

My solution is quite drastic: the destroyers are to be left to die. They've no fuel and aren't worth risking the crusiers over. The destroyers are ordered to try and link up with some xAK's off Wessel Island to refuel, while the crusiers are ordered to mount a full-speed run to the north-west, where they'll get some fuel from another group of xAK's that I left handy to cover an event like this.

The Mini-KB is ordered to cut back south and sit just off Wessel Island to attempt to cover the crusiers from the Allied ships right on their heels.

May 2nd

The out of fuel destroyers are wiped out by a monster Allied surface force:

Night Time Surface Combat, near Mornington Island at 85,133, Range 3,000 Yards

Japanese Ships
DD Asagiri, Shell hits 8, and is sunk
DD Yugiri, Shell hits 3, and is sunk
DD Mutsuki, Shell hits 6, and is sunk
DD Uzuki, Shell hits 12, and is sunk

Allied Ships
CA Pensacola
CA Salt Lake City
CA San Francisco
CA Quincy, Shell hits 1
CL St. Louis
CL Nashville
CL Boise
CL Honolulu
DD Cony
DD O'Bannon
DD Anderson
DD Hammann
DD Russell

Come daylight, though the Mini-KB is able to strike back, as the Allied crusiers have barreled right into range. Without air cover, the Allied ships are sitting ducks. The damage over the AM and PM phases amounts to:

CL St. Louis, Bomb hits 1
CA Pensacola, Torpedo hits 1, Bomb hits 1
CA San Francisco, Bomb hits 6, heavy fires, heavy damage
CA Quincy, Bomb hits 3, heavy fires, heavy damage
CL St. Louis, Bomb hits 2, on fire

With the Mini-KB covering their withdrawal, the Atago, Takao and Chokai refuel from the xAK's and head for Kendrai at full speed while the Mini-KB heads for Soerabaja at full speed.

May 3rd

Allied carriers at last get into the action, but find only the xAK refueling stations still in the area. The brave merchant ships are wiped out by American carrier aircraft, but their sacrafice enabled three crusiers to be saved.

All other Japanese shipping makes it safely back to port.

Conclusions

I got very, very lucky.

Lokasenna confessed via email that he messed up his upgrade settings, which forced him to delay getting his CV's into by two days. Without a doubt, this saved me. If Allied carriers had turned up on May 1st, it would have been a one-sided slaughter. Even though I had the sense to start running away, it would have still been too late for most of my ships.

I severely over-estimated the combat strength of the Mini-KB. It's handy for covering single invasion forces, but it simply isn't large enough to cover a large operation.

My planning was also pretty poor. Bar the obvious mistake (using MKB instead of KB), my frontline planning was pretty solid, but the rear-area logistics was a mess.

Operation Montcalm had the potential to be an absolute disaster, but it's somehow ended up as an awkward sort of draw. By some miracle I didn't lose anything bigger than a destroyer, and even managed to severely hurt (if not sink) some American crusiers. If all my learning experiances come at so cheap a cost, I'll be pretty pleased.

I never thought that base was worth the risk, fuel or supplies.

I see that now!

I had too much staked upon the element of suprise and Lokasenna having his fleet carriers further away than he did.

Retaking Merauke would only have been of minor use, and then only for a short time. I'd the notion of being able to build it up a little, so that my projection of air power into the Arafura Sea was a bit better, but I see now that any building attempts would simply be evaporated by Allied 4E's flying from Mainland OZ.

quote:

What was your CAP setting over the baby carriers? Using heavy bombers versus the KB is a good reason to stick to deep waters.


50% CAP, staggered altitudes. I think I left the range too high, which led to planes bouncing all over the place trying to fight off 4E attacks. One thing is for sure - the Arafura Sea is not the ideal battleground for a carrier clash - you've almost no searoom and there's plenty of bottlenecks that you can trap your carriers in.

I think one of the hardest things as Japan is managing the shift from butt kicking to defense with selected counter punching.
