Now for something I don't recall seeing before in an AAR: selected graphs generated by Woos' fantastic utility.

Until mid-April the manpower pool seemed to undergo periodic draw-downs and so maintained a relatively constant level. After mid-April the pool has maintained steady upward growth, the reason for which escapes me. Reduction in manpower requirements for re-inforcements, perhaps?

From the start of June I cut back on a number of areas where production appeared excessive, principally in merchant and aircraft construction. In particular I've been seeking an elusive 'sweet spot' at which shipbuilding pools remain fairly constant: currently that means that only 2 merchant yards are actually producing. The cutback on production of specifics seems to have boosted HI reserves substantially: currently I'm adding 10,000 points to the HI pool every 4th or 5th day. At that rate of increase the pool would top the million mark in just over a year (1943, Q3), but I doubt that this rate of increase can be sustained.

Woos' utility is particularly helpful because it takes account of cargo in transit, so I get a much more accurate indication of trends than appears from my own stockpiles spreadsheet, which has to be based upon oil and resource levels as revealed by the game's intelligence screens. As can be seen, there's a slight but healthy upwards trend in oil stockholdings, and a correspondingly worrying decline in resource stocks.

Note the 2 step-downs in oil output at about the 180- and 200-day marks. None of my oil centres suffered any damage at these times, so the reason for the production drop is something of a mystery. Can anyone supply an explanation?

Oh, and I do know how to spell 'Fall', but for some reason the second 'L' seems to have gone walkabout due to some side effect of JPEG compression. <edit - weird, as uploaded it appears OK, but not in my computer's image viewer>

And a second set of graphs, this time covering equipment and victory points.

From about the end of April the armaments pool began to show a fairly steady rate of enlargement, presumably due to expansion in capacity reaching the point at which production is consistently outpacing the demand for replacements both at the front lines and from arriving re-inforcements.

The vehicle graph has, until recently, followed a reliable pattern in which accumulated stocks are drawn down almost in their entirety at intervals of approximately 10 days. However, the last cycle began on 16 June and there has been no subsequent withdrawal from pooled stocks, giving a current pool level of 2279 units. Daily production has grown, but only slightly, so some other factor is at work here.

Summary for June 1942

C-in-C Combined Fleet's pre-war prediction has been made good in part: Japan has had unbroken success for 6 months. But the rate at which those successes have been harvested has slowed considerably, and Japanese gains in June have been meagre compared to what has gone before.

On 2 June, with nowhere to run, the Australian defenders of Daly Waters turned to confront the pursuing 16th Japanese Army. To no avail! One unit to the south of Daly Waters continued to elude the Japanese, but, after repeated attacks upon it by the single brigade of infantry and regiment of tanks assigned for the purpose it surrendered on 24 June, proving to be ANZAC HQ. Pleased though I am to have eliminated a command HQ, I'm told by my worthy antagonist that it respawns in due course. I assume, however, that SWPac HQ was already based in Australia, so the damage to the Allied cause is probably not great.

On 4 June a Japanese force having an adjusted AV of 3355 assaulted the defences of Pucheng, which promptly collapsed, with the result that Chinese defenders totalling 26,754 became captives or casualties, as against Japanese casualties of 2,732. The victorious units immediately began their laborious march out of the woods, some towards the sole remaining Allied enclave in E China at Wenchow, the others towards a new campaign at... well, that can be a story for another day.

Elsewhere in China, Chinese forces have been repeatedly bombarding Japanese defenders of the woods immediately to the west of Nanchang, and moving additional units into this area. Whether this presages a Chinese infantry attack remains to be seen, but if so it seems likely the attackers will be repulsed.

Meanwhile, Chinese forces advanced into Canton, launched some exploratory bombardment attacks, seem not to have cared for the force level they encountered and have apparently begun to retreat again!

On 11 June the Japanese began a landing operation they had better accomplished back in February: the first troops went ashore at Thursday Island under cover of bombardment by battleship Kongo and cruiser Mikuma. On the same day a small force of paratroops descended on Portland Roads and occupied it briefly before being withdrawn by seaplane tender Mizuho and accompanying minesweepers.

For some reason US submarines had frequently been observed at Portland Roads, and one had been regularly patrolling Port Moresby. Confident that any submarines in the area would immediately converge on the invasion forces at Thursday Island, the Japanese took the opportunity to run supplies and re-inforcements into Moresby, and these were landed without interference from submarines. Simultaneously, R Adm Hara's fast replenishment group transited Torres Strait and joined the transports at Moresby, where these task forces combined for a maximum speed run to Rabaul. This move has ensured that ample oiler support is now available for future operations in the Solomons and points east.

Anxious to avoid unnecessary exposure to submarine attack at Thursday Island the bombardment group retired on Merak, there to rendezvous with battleship Haruna and hold ready to respond to any Allied surface intervention. Alas! The Japanese surface search effort was not equal to the task, and a joint US-Australian task force took the invaders' naval forces in the vicinity by surprise on 12 June:

Day Time Surface Combat, near Thursday Island at 49,91

Japanese Ships
DD Mikazuki, Shell hits 17, on fire, heavy damage
APD Patrol Boat No. 39
PC Kunashiri
PG Keiko Maru
PG Kure Maru #5

Allied Ships
CA New Orleans, Shell hits 2
CL Perth
CL Raleigh
DD Bagley
DD Patterson
DD Jarvis
DD Mahan, Shell hits 1, on fire
DD Cummings
DD Case

--------------------------------------------------------------------------------
Day Time Surface Combat, near Thursday Island at 49,91

Japanese Ships
DD Mikazuki, Shell hits 3, and is sunk
APD Patrol Boat No. 39
PC Kunashiri
PG Keiko Maru, Shell hits 5, on fire, heavy damage
PG Kure Maru #5, Shell hits 4, on fire, heavy damage

Allied Ships
CA New Orleans
CL Perth, Shell hits 1
CL Raleigh
DD Bagley
DD Patterson
DD Jarvis
DD Mahan, Shell hits 1, on fire
DD Cummings
DD Case, Shell hits 2, on fire

Faced with an overwhelmingly superior force, V Adm Hosgaya's ASW group gave an admirable account of itself in the circumstances, twice successfully interposing itself between the Allied task group and the near-defenceless transports. Those transports remained untouched, but it was at heavy cost to the ASW group. Mikazuki was mortally struck in the first engagement and went down early in the second, having achieved nothing by her torpedo salvo. Kaibokan Kunashiri and APD 39 bore charmed lives, but the two patrol craft Keiko Maru and Kure Maru #5 subsequently succumbed, Kure Maru being scuttled at Moresby, whilst Keiko Maru actually made it to Rabaul but could not overcome accumulating flotation damage. Would that Haruna and Mikuma had been retained on station!

Although the Japanese immediately re-inforced Lae with land attack aircraft, none of them subsequently contested the Allied raiding group's retirement down the E coast of Australia, notwithstanding minimal fatigue to the bomber crews and the raiders having remained under observation.

Thursday Island duly fell to 4th Mixed Rgt's assault on 13 June.

At the end of a quiet month there was something of a flare-up, as on 29 June a US carrier group centred on Hornet raided Tarawa and caught a re-supply convoy there. Japanese float fighters seem to have taken some of the sting out of the attacks, which nonethless left destroyer Akebono and a transport moderately hard hit.

Meanwhile, at the western extremity of the Co-Prosperity Sphere, Dutchman KXVIII sank a torpedo into the side of destroyer Tanikaze at Penang, wounding her severely. However, Tanikaze's consorts counterattacked with vigour, apparently doing serious damage to the interloper.

And this same day a group of merchantmen sailing suspiciously close to Akyab came under attack from Rangoon's land attack planes:

Day Air attack on TF at 29,27

Japanese aircraft
A6M2 Zero x 9
G4M1 Betty x 19

Japanese aircraft losses
G4M1 Betty: 1 destroyed, 3 damaged

Allied Ships
AK Dunedin Star, Torpedo hits 4, on fire, heavy damage <subsequently sinks>
AK Coquina, Torpedo hits 1, on fire
AK Empire Avocet, Torpedo hits 1, on fire, heavy damage
AK Dardanus, Torpedo hits 3, on fire, heavy damage <subsequently sinks>

Aircraft Attacking:
2 x G4M1 Betty launching torpedoes at 200 feet
4 x G4M1 Betty launching torpedoes at 200 feet
4 x G4M1 Betty launching torpedoes at 200 feet
4 x G4M1 Betty launching torpedoes at 200 feet
4 x G4M1 Betty launching torpedoes at 200 feet

So with six, nearly seven months gone, can we now confound Yamamoto Isoruku's pessimistic assessment? -

"For six months I shall run wild and win victory upon victory, but after that I have no expectation of success."

I was missing this AAR, nice to have it continued.

Let's hope Yamamoto was wrong in this war. :) Nice progress, smells like an auto victory come 1942. Not much he can do to prevent it.

Thanks! I'll try to keep the updates coming, normally at intervals of game-months unless some notable action takes place.

Jonathan has been a first-class opponent to work with, and I've approached this game on the basis that he deserves the opportunity to get his own back. So auto-victory, though 'nice to have', isn't really a consideration - I'm assuming we play beyond it if it's attained, on the footing that the US would not have gone back on a demand for unconditional surrender.

However, if he wants to forestall auto-victory it looks as though he's going to have to make a major effort somewhere before the end of the year. After getting his nose bloodied at Tarawa I'm guessing that his main effort is most likely to be towards New Hebrides/New Caledonia, with a 'Northern Route' campaign as a less likely alternative. In either case, I'm looking forward to opportunities to inflict losses through defensive battle, so the next six months could prove to be interesting.

It is late June 1942. Outside, the early summer air is warm, and in the new annexe to the Navy Department building in Kasumigaseki the windows of the Plans Room have been thrown open. Within, Rear Admiral Fukudome Shigeru and Captain the Baron Tomioka Sadatoshi, head of the Plans Division of the Naval General Staff, gaze upon a vast map of the Pacific. They are contemplating an intractable problem: how to bring the US Navy to battle whilst the Imperial Navy still retains parity, if not a degree of ascendancy over its foes.

The problem is intractable because there is no reason to expect that the Americans will come out to play at the bidding of the Japanese. How and where can the Japanese provoke a US response other than on terms that favour the Americans? Fiji, Samoa, or the Line Islands? Traffic analysis shows that all are bristling with land-based air assets. Midway? Although it is apparently lightly defended, there is no reason to suppose that the Americans will be sure to respond to its seizure. And the Japanese are well aware of the perils of assault upon an atoll. The Aleutians? Why would anybody want to contest tenure of this barren island chain? From the purely naval viewpoint, therefore, the Japanese have absolutely no reason to suppose that the Americans will choose to sally forth until their economic superiority has shifted the balance of naval force firmly in their own favour.

And yet… Fukudome and Tomioka have the sense that one of the thrusters is in charge of US naval operations in the Pacific. The first hint of this came from the imprudent landings upon Tarawa and Makin in April, which the Japanese rudely repulsed. On 23 May a light carrier was spotted some 200 miles east of Efate. Again, on 9 June carrier Enterprise was glimpsed just west of Fiji. And reports have just been received of a carrier raid, apparently by Hornet, on Tarawa. The Americans seem prepared to risk their carriers on pinprick raids directed towards the Gilberts and the New Hebrides, where the bulk of their bombing and reconnaissance effort suggests their first counter-offensive is most likely to be launched.

The Japanese naval planners are encouraged by these straws in the wind. The North Fiji Basin is a battle space they can dominate. They already have deployed several units of torpedo-carrying land attack aircraft at Noumea and Lunga that can mount escorted strikes far into this area. And at both these locations they also deploy the finest maritime patrol aircraft in the world: the Kawanishi Type 2 flying boat, supplemented by its Type 97 predecessors based at Espiritu Santo. Furthermore, Tulagi has now been developed sufficiently to act as a forward base and battle repair facility for the fleet carriers in 1st Mobile Force. The basic elements of the Japanese plan, therefore, are to stage their striking force to point lying to the west of the Santa Cruz Islands. They will do this provided sufficiently early warning is received, probably from Noumea’s Type 2’s, of a carrier sortie coming out of Fiji. The hope is that 1st Mobile Force can then pounce with its full force, supplemented by the efforts of Noumea’s land attack aircraft. The Japanese superiority at the point of contact is expected to be decisive.

As it happens, the first essay of such a scheme coincides conveniently with arrangements to reinforce Espiritu Santo. Accordingly, 1st Mobile Force will precede the reinforcement convoy into the area, ready to intervene if the convoy is threatened by an American carrier raid. Simultaneously a second convoy will reinforce the Lower Solomons; this will be accompanied by two newly-delivered repair ships that will base on Tulagi and provide immediate assistance to carriers damaged in any scrap that may develop.

Fukudome and Tomioka expect the Americans to be wary, however. They judge that their foe may need re-assurance before committing his carriers to another raid in the South Pacific. Therefore, they plan to provide that re-assurance by mounting a carrier raid in the North Pacific. Dai-ni Kido Butai – 2nd Mobile Force – has been covering a re-supply convoy to Attu, and disposes some 260 aircraft: not so many as its more illustrious stablemate, to be sure, but enough, the planners hope, to encourage an American belief that the preponderance of Japanese carrier strength is deployed in the North Pacific.

For some time Japanese reconnaissance aircraft have been feeling out the extent of Allied activity on Adak, and it has become clear that major port and airfield development is under way here, with a corresponding increase in the number of naval attack aircraft hosted. Further east, however, the Americans have yet to extend their facilities on Unalaska. Whilst the vulnerable light carriers of 2nd Mobile Force would be exposed to grave peril from the air in an attack upon Adak, the planners judge that a strike against Dutch Harbor can only be opposed by interceptors, and may yield excellent results against Allied vessels in the anchorage there.

The strike against Dutch Harbor requires some careful planning. Allied search aircraft based at Adak preclude a direct approach of the strike force along the Aleutian chain. Instead, 2nd Mobile Force must be routed well to the south through the empty wastes of the North Pacific, following a route substantially similar to that taken in the Hawaii Operation. Careful positioning should then permit the strike force to make a high speed run-in unseen, hit the base and then retire within the space of two days, it is hoped thereby evading Allied counter-measures. The operation is higher risk than those projected for the South Pacific, as the strike force will be operating in territory well beyond Japanese air surveillance. For success it must rely upon exclusively upon surprise and indirectness of the approach.

Fukudome and Tomioka cast about for a codename for the operation. It is to be one in two parts: a feint to the north and a strike to the south, and its burden will largely fall on the Japan’s naval air arm. They remind themselves that much of the training for the strike on Pearl Harbor took place in Kagoshima Bay, under the shadow of the multiple peaks that make up the highly active volcano Sakurajima. Very well then, ‘Sakurajima Sakusen’ shall be the operation’s name, and its two elements abbreviated to Sa-GO Hoku and Sa-GO Nan: the North and South sub-components. And in a manner reminiscent of the Hawaii operation the planners allocate activation codes for the two parts of the operation that reflect the names of the northern and southern peaks of Sakurajima: ‘Kitadake wa haretari’ (‘Kitadake has cleared’) and ‘Minamidake wa haretari’.

It is the morning of 7 July 1942. Charging through the swells of the South Pacific some 180 miles east of the New Hebrides at close to her maximum speed, the USS Enterprise is turning into the wind to launch her strike aircraft against Espiritu Santo. The radar watch aboard has been monitoring a distant bogey in the north-west quadrant, but hitherto this has been left to its own devices whilst it remains outside visual range. Now, however, the watch note that the bogey’s range is closing, and a division of F4F’s is vectored towards it for an interception.

Presently the division leader sights the intruder and as the fighters draw near it is identified as a large Kawanishi flying boat with parasol wing. The Japanese snooper is not slow to realise it’s been spotted, and the big aircraft abruptly banks away towards the nearest cloud formation. Too late! The Grummans are tearing in and their leader’s second burst rakes the wing in the vicinity of the port inner engine which immediately erupts oil and seizes but mercifully for the crew fails to ignite. Further bursts from the American fighters reduce the tail assembly to tatters and kill the gunner in the tail gun position. Now, however, the Kawanishi has found the sanctuary of the cloud and the frustrated interceptors mill around its margins in the vain hope of regaining contact, whilst within the cloud the flying boat’s wireless operator is busy keying his report of the engagement back to base.

Some 90 minutes later the damaged flying boat flops into the waters of Palikulo Bay on the east side of Espiritu Santo (where it will later be adjudged a write-off) just ahead of the arrival of the US carrier strike. 14 SBD’s plunge down on Luganville, doing negligible damage but suffering no loss in return. Even as the harsh roar of their engines recedes to the east, retribution is on its way in the shape of a small formation of Type 1 Land Attack aircraft belonging to the Genzan kokutai based at Noumea. Alerted by the Kawanishi’s action report the Japanese have moved with lightning speed to launch a counter-strike, notwithstanding that it must seek a target some 600 miles distant, at the extreme range of the 3 Reisen that accompany the bombers.

It is mid-afternoon before the Japanese gaggle attains the predicted position of the American task force, but luck is with them as the captain of the Rikko on the extreme left of the formation glimpses ship wakes some miles off to port. The group splits into two 4-aircraft sections that separate in an attempt to catch the enemy in a deadly scissors attack, but soon they are having to contend with the 5-strong CAP of F4F-3’s. The accompanying Zeroes are largely successful in fending the Grummans off one group of bombers, but the other group suffers repeatedly from the fighters’ attention, and it is not long before one of its number blooms into a spectacular blaze that is only quenched when the bomber falls into the sea below. Not for nothing will the Rikko become known to its crews as the ‘Type 1 firelighter’.

As they bore in on Enterprise, the intense small-calibre fire put up by its gunners suffices to throw off the aim of six of the seven survivors, but this is an attack from which the carrier will not emerge unscathed, for the determined Petty Officer at the controls of the seventh holds his machine steady enough and long enough to put his aircraft’s weapon into the water accurately. The Type 91 torpedo knifes through the swells and strikes the carrier abreast of a magazine. The ship shudders from the concussion as a geyser of water from the exploding torpedo soars above flight deck level, followed shortly after by a plume of smoke shot with fire as ordnance in the magazine begins to cook off in a series of induced explosions.

Still harried by the F4F’s as they retire to the south-west, the crews of the surviving Rikkos occasionally cast awe-struck glances back the column of smoke that roils ever higher from the stricken carrier, and in their leader’s plane the wireless operator is tapping out his success message to Noumea, reporting the grid square in which the attack took place and that the hoku bokan attacked has been left burning.

With the successful torpedo strike by Noumea’s aircraft on 7 July, the Japanese operation Sa-GO Nan bears fruit far sooner than expected. The American carrier is wounded and on fire, but presumably still capable of making reasonable speed out of the danger zone.

Unfortunately for the Americans, they have more to contend with than land based aircraft. The American carrier strike has happened to coincide with the move south by 1st Mobile Force as it covers the reinforcement convoy proceeding to Espiritu Santo. By the evening of 7 July all six Japanese fleet carriers are concentrated sixty miles west of Ndeni. On learning of the successful strike by aircraft of the Genzan kokutai that afternoon, they commence a high-speed pursuit on a south-easterly course.

The Japanese commanders have to contend with two likely scenarios: the American task force will retire towards Fiji and will make port at Suva by one of two possible routes: northabout between Vanua Levu and the Yasawas to the west, or a more southerly course that will take it round the west coast of Viti Levu. The solution adopted is to bisect the angle between these two courses and rely upon the carriers’ speed to close by up to a further 120 miles (max react 2) once the enemy’s location has been established. Calculations indicate that, even if the American carrier has been able to resume something approaching full speed, she should still come within range of Japanese carrier strikes on the following day, whilst the Japanese forces should remain outside torpedo strike range from Nandi.

As it turns out, Enterprise has been obliged to move at greatly reduced speed and has only made a day’s run of 360 miles by the time she is attacked by Japanese carrier aircraft. Moreover, the damage suffered from the initial torpedo hit has sufficed to preclude flight operations, so leaving her utterly defenceless but for AAA.

The result is something of an anti-climax, and more in the nature of an execution than a real fight:

In exchange for two carrier bombers destroyed, the US carrier suffers hits from no less than forty-five 250 kilo bombs, whilst in a subsequent strike USS Detroit suffers the impact of five torpedoes. Both are observed to sink, and the Japanese in addition do significant damage to Vincennes, Atlanta, Anderson and Hammann.

Equally anti-climactic is the other element in Japan’s Sakurajima operation: Sa-GO Hoku. Notwithstanding the success of the southern element, the Japanese command judge that the damage a strike on shipping at Dutch Harbor will inflict warrants the risks involved, and the activation code ‘Kitadake wa haretari’ is accordingly flashed to Yamada’s 2nd Mobile Force on the evening of 9 July. The force thereupon begins its own high-speed dash to a launch point 180 miles south of the target, only to find on arrival that weather conditions are so atrocious as to prevent the launch of any strikes either during the morning or afternoon. This is all the more galling as reconnaissance sorties over Unalaska confirm that the anchorage is packed with a rich assortment of targets including the bombardment group that hit Attu two days earlier.

Great AAR, love the detail and use of combat reports only when necessary

Also, grats on sinking Big E, anti-climactic though it was.

Welcome to two new contributors; glad you're enjoying!

For the graphics I started out with nothing other than MS Paint, but recently I've started to do some of the work using Paint.NET, which I think was drawn to my attention by ctangus. It's a free download; go here for more details. The feature I've found most useful so far is the ability to bend lines, as these are basically Bezier curves, I believe.

The maps themselves are the hex-free maps you can download for CHS, but since the overall map is broken down into a number of separate files which seldom correspond to the area you want, you will need to do some 'copy and paste' work to create a new map file for the area you want to display. Obviously you want to leave the original map files intact - they should get installed to <WitP root directory>\ART\Maps_Modified_v6X or something similar.

Hope that gives some idea of my approach - I'll try to amplify if necessary.

Too bad about Sa-GO Hoku. Will you linger about and wait for the weather to clear or is it too much of a risk?

Note the 2 step-downs in oil output at about the 180- and 200-day marks. None of my oil centres suffered any damage at these times, so the reason for the production drop is something of a mystery. Can anyone supply an explanation?



I'm not sure if this is the case in your game, but I've noticed that resources & oil centers seem to stop producing once they've stored 100 days worth of production. E.g. Medan - 50 oil centers x 6/day x 100 days = 30,000. It won't produce anymore once it has that much in its tanks. Perhaps a couple of your bases have reached their threshold.

And congrats on the Enterprise! Surely the Imperialists will never recover from such a devastating blow!

You've established an impressive perimeter. I'm curious - do you plan more expansion at this point? Dig in? Combination of both?

It's interesting to analyse the composition of the Japanese carrier strikes.

Strike 1 is of comparable size to each of the Pearl Harbor attack waves, and consistent with a full deckload spot for all 6 carriers.
Strikes 2 + 3 look like another full deckload spot that got broken down into two elements, one attack plane-heavy, the other carrier bomber-heavy.

Strike 3 is BS: 280 aircraft is way above a deckload spot and would involve a large portion of the strike orbiting the carriers whilst the remainder were ranged on deck, warmed up and launched: an operation that would have taken 30-60 minutes IRL. I'm confident the Japanese would have stuck to doctrine and launched two more deckloads of about 140 aircraft apiece.

FWIW, I'm strongly opposed to any range penalty being imposed on Japanese carrier aircraft BUT I would like to see their strikes limited to the equivalent of full deckloads. And the purist in me says that attack planes launching from CVL's should not carry torpedoes, whilst CV's Hiyo and Junyo should only launch up to 6 torpedo-armed attack planes, again as IRL. In the early years at least the Japanese had a range advantage and they should be allowed to exploit it if they choose.

Sa-GO Hoku was indeed a disappointment, given the target-rich environment. I could probably have got away with lingering another day, but force conservation is paramount, and there will be other opportunities in less exposed waters. Also, bunker levels soon go critical after a high speed run, and I have to retain a fuel margin to meet contingencies whilst I'm en route to the rendezvous with my oilers. So, I'm taking a leaf out of Frank Jack Fletcher's book and 2nd Mobile Force is currently beating a retreat (and has been observed in so doing by search a/c out of Adak).

Sorry about that.

That's a really interesting point about storage capacity that I must check.

One problem I have noticed is my 'embarrassment of riches' resulting from the intact capture of Palembang, with about 500,000 units of oil. I've been trying to disperse that accumulation using a shuttle of 6000 capacity TK's to move part of the stockpile east to Brunei initially, in addition to long haul oil movements to the HI. What I'm finding is that is that there are simply not enough tankers to make serious inroads into the oil stored at Palembang, which keeps churning more of the damn stuff out - no sign of storage capacity being a limiting factor there, so far as I can tell.

Incidentally I may have stumbled on a good solution for getting best use out of the whale factory ships in CHS: confine them to the Brunei-HI run. This way they can join up with a convoy of 10000 capacity TK's homeward-bound from Palembang, and get the extra loading time they need without delaying the smaller tankers that load closer to the perimeter.

It was very unfair of me to get a 6 to 1 advantage in carriers against Enterprise - I'm so disappointed with myself

I've been assiduously digging in round the perimeter for some time already: e.g. one base in the Marshalls already has max forts and another will do so any day now.

As for further expansion, I'm very much in two minds. My conservative instincts tell me I've got a good distribution of forces that can hold critical locations long enough to be relieved and mount a counter-attack. OTOH, logically I should pursue my offensive strategy to its conclusion by establishing air bases in N Zealand as the only effective way to sever the US-Australia SLOC. If I don't do that then it's arguable that I have no business being in Noumea (except to torpedo enemy CV's, hehe). But an amphibious operation against NZ is a big roll of the dice: it's putting a lot of troops and ships in harm's way and involves a big outlay in fuel and a large and continuing supply commitment. I've actually got some units prepping for such an operation, but putting the necessary logistics in place will take some time yet. This may mean that my window of opportunity for such an op may close before I can launch it anyway.

Any thoughts?

You gamer!

In truth I'd say you played that extremely well. Your opponent was taking a risk using a CV independently like that. I've done the same (and have paid for it!) You had a well-conceived plan. While it didn't work out exactly like you expected, I'd still say you did a good job there.

Boy, I'm debating many of the same things myself currently. I can provide some thoughts, but I don't know how good they'll be.

July '42 seems a little too late for me to conduct major offensive operations. Some players, better than me, have done so successfully. But it'd be risky. Even this early the Allied LBA has significant teeth...

Minor offensive operations could still be easily achieved. For one thing I believe you don't have the Ellice Islands yet & they would help you out - they keep you a little further from allied fighter range.

An offensive op against NZ? If successful it would certainly be very beneficial. But it also seems too risky to me. I don't think the risk is worth the reward - with your current position I'd say you're in very good shape. You should already be able to delay the evil imperialists for many, many months. If you took NZ it would delay them a little bit more, but it would probably require you risking much of the Combined Fleet...

Risk/reward ratio doesn't seem to be worth it to me. I think you'd be better off saving your strength to vigorously counter-attack and/or reinforce the first allied offensives.

I'm not sure how good they are, but those are my thoughts...

Actually, they're thoughts very similar to my own.

Let's take the analysis of a New Zealand oparation a bit further, and let's take it as read that even now I can bring enough force to bear to ensure capture of, say, North Island. The immediate effect should be to create a barrier across US-Australia sea communications; the size 6 air base facilities at Auckland should see to that.

In principle Australia can still be reinforced/re-supplied via Aden, but I think it's reasonable to assume that the Allies would see re-establishment of an open sea route to Australia as a desirable preliminary to later offensives. Indeed, operations to open that route hold attractions for the Allies inasmuch as they involve a strike against an extended chain of bases that form the barrier. Maintenance of that barrier requires the Japanese not only to sustain a respectable garrison of North Island, but also mandates equally strong garrisons of the intervening links in the chain, in the Lower Solomons, New Hebrides and New Caledonia. That requires a major force commitment and still carries the risk that rupture of the barrier isolates the units beyond the breach and exposes them to destruction in detail. Thus, rather than being able to dictate the choice of battleground to its own advantage, Japan yields that choice to its enemy and immediately commits itself to fighting the defensive battle at a disadvantage.

So I conclude that New Zealand can only be regarded as a defensible objective if its capture forms part of bigger operations aimed at giving greater breadth to the barrier, i.e. by the capture in addition of Fiji at least. All of which merely enlarges Japan's force allocation at a single, non-productive point on the periphery, which doesn't strike me as a sound policy to be adopting.

Damn! I think I just invalidated my own strategy!

No, I think you're right to think in terms of conserving strength for the counterattack. Not only does this preserve the opportunity to cripple some of his high quality assault troops, but it also gives strength and depth to the defence.

Psychologically, I believe I have an opponent who may be too keen to go over to the attack. I think he may be provoked into mounting further offensives prematurely. In any event, I believe he may well have to mount any such offensives at places where I have a positional advantage, and in that case I may have the chance to make him pay disproportionately for his gains. Perhaps I should try to panic him by hinting at the growing fort levels he will have to face - Wake just went to 9.

By way of a taster, here is a map showing the Aleutians situation on 24 July 42. I had just completed this when the next turn arrived, so I'll post a further update after I've been able to get something back to my worthy foe.

Action off Attu, July 1942

Prelude: Hittokappu Bay, 18 July 1942


Almost eight months have passed since the heavy carriers of 1st Air Fleet disappeared into the November twilight off Etorofu-jima, bound for their appointment at Pearl Harbor, and following their departure Hittokappu Wan reverted to being a backwater of little consequence.

Today, however, Hittokappu has once again been transformed into a scene of frantic activity. During the night the carriers of 2nd Mobile Force came gliding into the anchorage after their fruitless foray to Dutch Harbor, the northern component in Japan’s Sakurajima Sakusen. The sortie has stretched the force to the limit of its endurance, and base force personnel swarm over the ships to connect fuelling hoses to their near-empty bunkers.

Later in the day the gathering is swelled by the arrival of the main body of 1st Fleet: battleships Ise and Hyuga with their supporting cruisers and escorts. Combined Fleet has ordered these heavy units out from Maizuru in anticipation of a new operation in northern waters, details of which are delivered to the participating commanders by the C-in-C personally that afternoon, the flying boat bearing Yamamoto having alighted in the bustling anchorage shortly before lunchtime.

Since no co-ordination of forces at opposite ends of the Pacific is involved, this is Combined Fleet’s show. It is one prompted by the bombardment by US cruisers of Japanese positions on Attu Island on 7 July, and a subsequent feint towards the island by another surface force on 13 July. Combined Fleet believes that the US command at Dutch Harbor intends to mount a further raid against the island and plans to meet it with an ambush. By way of encouragement, a convoy with reinforcements for Attu is en route from Yokosuka, and it is hoped that the arrival of its transports off Attu will serve as bait to the Americans.

In fact, the defences at Attu are also to be augmented substantially by a major mine laying operation, and in view of the presence of the obligatory submarine patrol offshore (in this case a US ‘S’ boat), the minelayers and the reinforcement group will be preceded into Attu waters by 5th Escort Force, which will endeavour to suppress, if not sink, the marauder.

Meanwhile, the heavy units from 1st Fleet, reconstituted under R Adm Onishi as Attu Guard Force, will escort the transports to a point 100 miles west of Attu, where the Guard Force will loiter undetected to await sighting of an American raiding force approaching from the east. If this occurs, the transports unloading at Attu will retire to the south-west and their place will speedily be taken by Onishi’s ships, which it is hoped will be able to surprise the raiders with overwhelming firepower.

Combined Fleet is aiming for a clean sweep, and to achieve this has planned for Yamada’s carriers to patrol some 50 miles northwest of the Kommandorskis. As soon as an approaching US task force is detected, Yamada will make a 400-mile dash on an ESE course, designed to put him within torpedo striking range of the retiring survivors of the engagement with Onishi, but outside the range of an effective counter-strike from bombers based on Adak. If the situation warrants Onishi may also detach light forces in pursuit of the fleeing foe.

The plan is, of course, dependent upon timely sighting of the incoming US surface group, but past experience gives the Japanese confidence this can be accomplished. By way of insurance, however, search assets are enhanced by redeployment of the P7 Yokosuka Chutai’s Type 2 flying boats from Etorofu to Paramushiro, and intensification of search activity by submarine-borne floatplanes off Dutch Harbor.

Given that on at least one previous occasion a threatened Allied raid has turned out to be no more than a feint, there is one remaining element in the Combined Fleet’s plan. Lt Cdr Kishigami’s I-124, heavily laden with mines, will lurk to the NE of Dutch Harbor, hopefully clear of the traffic pattern, to await news of a sortie towards Attu. Thereupon Kishigami will proceed at high speed to Dutch Harbor and lay his offensive minefield in its approaches. It is hoped that this will either catch a returning Allied warship if the sortie proves to be a feint, or a survivor of any engagement with Onishi off Attu.

Action off Attu, July 1942

Toccata: Waters east of Attu Island, night time, 24-25 July 1942


In the late hours of 23 July R Adm Yoshitomi’s 5th Escort Group makes landfall at Attu, and is almost immediately in contact with the US Sugar boat that is stalking the island’s approaches. Patrol Boat 31 makes what seems to be an accurate attack on the submarine, but with hindsight the damage appears to have been less than is initially hoped, and almost certainly the submarine gets a contact report off to the Allied command for the North Pacific. The ‘S’ boat bears away westward, and the Japanese, confident that the way is clear to land their reinforcements, order Takeda’s group of transports to enter harbour, followed by Cdr Sanami’s minelayers.

On the following day, an Army Ki-46 reconnaissance plane sights a force of Allied warships about 350 miles due east of Attu. The observer reports them as three heavy cruisers and one light cruiser, and his report is judged to be the sighting of an oncoming bombardment group, expected to include CA Chester and CL Trenton, both of which participated in the previous bombardment of Attu on 7 July.

For once events are proceeding exactly in accordance with the Japanese script, and Combined Fleet’s ambush plan is immediately put into operation. The transports hurriedly quit the vicinity of the island, the plan being for Sanami’s minelayers to follow after laying their cargoes. This exercise miscarries, as the minelayers do not receive the necessary order to lay, but it matters little for they remain undetected. Yoshitomi’s escort group heads out to sit on top of the Sugar boat, keeping it down whilst Onishi’s Guard Force rushes in from the west at top speed, ready to confront the expected US bombardment group that is approaching from the east. Meanwhile Yamada’s carriers begin their run from Kommandorski Island to the predicted launch point against the survivors of the night-time clash. Location of these is to be assisted by the eight Type 0 seaplanes embarked in Kimikawa Maru, which also begins a high-speed advance to a point NE of Attu.

For a change the seas around the Western Aleutians are not wracked by storms, but instead the opposing navies must contend with that other staple of Aleutian weather: dense fogbanks that drift aimlessly across the warships’ path, impenetrable to the Japanese lookouts’ superb 12 cm binoculars, but no obstacle to the radars that now adorn the masts of their opponents. So it is that the oncoming Americans get wind of the Japanese presence well before the starboard lookout on Onishi’s van destroyer, Oshio, first glimpses the sparkle of destroyer Smith’s bow wave as the American force breaks free from the confines of the fogbank that has cloaked it to a point not 4000 yards distant from the Guard Force.

There, however, the American advantage ends, for although the radar’s warning alerted American commander Shock to his enemy’s proximity, his jaw must have dropped as the parting fogbanks reveal the presence, not of Yoshitomi’s expected anti-submarine ships, but the towering pagodas of Onishi’s two 14” battleships. These are accompanied by three cruisers and a half-dozen destroyers, all of whom are frantically training their torpedo mounts in the direction of the Americans and cranking in a hastily computed firing solution.

Possibly because the sudden appearance of the Americans has taken them by surprise, the aim of the Japanese destroyer men is not good – with one notable exception. Lieutenant Sugiyura has drilled his crews well, and the second weapon fired from Hibiki’s forward torpedo mount finds its mark in the starboard quarter of CL Trenton, in way of the cruiser’s torpedo storage. Immediately Trenton is in desperate straits: the hull’s structural integrity has been seriously compromised and propulsion off the starboard engine is lost at once for reasons which, in view of the events that shortly follow, will never be known. Additionally, one of the ship’s SOC seaplanes is now blazing fiercely, and serving as a convenient aiming mark for the Japanese gunners. Possibly it is due to this that shortly thereafter Ise succeeds in landing three, perhaps four 14” rounds on Trenton, one of which ignites the forward magazine and thereby ensures the ship’s complete destruction.

There follows a brief but violent melee in which Hibiki, concentrating her fire upon Trenton, receives two damaging hits from Smith. Smith in turn takes an 8” round from Takao, whilst Hyuga manages to land a 14” hit upon destroyer Hughes. Vanguard destroyer Oshio pours further fire upon Hughes until the latter likewise succumbs to a magazine explosion. Meanwhile Hyuga’s secondary batteries dish out punishment to both Hughes and Clark before the two surviving US destroyers succeed in ducking into the cover of a fogbank.

Both of the American ships are now well alight, however, and the glow from their fires flickering within the fog serves to lead the Japanese to them, so that it is not long before the Guard Force acquires and re-engages its quarry, this time at an opening range of 9000 yards.

And this time the traffic is almost exclusively one way. Though she too is alight, Onishi cannot refuse Hibiki’s request that she be allowed to close survivor Clark, and her guns pound the US destroyer mercilessly, landing no less than fifteen 5” hits and leaving her opponent a useless hulk. Meanwhile Hyuga and Takao concentrate on Smith, so as to leave her, too, a flaming wreck by the time the Japanese break off the action.

Comes the dawn, and the two limping US survivors are located 60 miles south-east of Attu, presumably making a forlorn bid for the haven at Adak that is still more than 300 miles distant. The intervention of Yamada’s aviators is almost certainly superfluous, and it is ironic that the US force has been so severely handled that its remnants are unable to retreat far enough to come within torpedo strike range from Yamada’s carriers. Regardless, the primary strike of 32 bomb-laden attack planes goes in and despatches the wrecked American warships with four further hits apiece. When the follow-up strikes by Junyo’s dive bombers arrive on the scene they find nothing amid the fog patches but long slicks of oil and floating debris: the detritus of defeat.

End-of-month reports for July, beginning with Aircraft Production/stockpiles and Economy Summary:




Ki-44 Shoki production begun and ramped up, with 85 produced in the month - no deliveries to squadrons as yet; I'm hoping to roll 'em out en masse. Production of the Ki-61 Hien begins tomorrow!

Next, the updated stockpiles graph. Fuel stocks picking up again after extensive replenishment of bunkers, both warship and merchant. Oil and resource stocks look low, but there's lots at sea at the moment.

The Intelligence Summary screen. Allied aircraft losses 'distorted' by the loss of Enterprise's airgroup, apparently in its entirety.

I followed up on ctangus' very helpful suggestion that there may be a ceiling on a base's oil storage capacity. At Brunei I had accumulated oil stocks more than 200% in excess of daily production X 100, and it appeared that this had stopped oil production at Brunei dead in its tracks. I took urgent action to shift some of the excess out of Brunei, and it looks as though this may have cured the problem:

End of Month Summary for July 1942

A comparatively quiet month, but a highly satisfactory one for Japan at sea, all at the expense of the USN, which suffered the loss of a fleet carrier and two Omaha class light cruisers during its course.

The emphasis has been on building the defences throughout Japan’s conquests. Early in the month Truk received major reinforcements and additional supplies, and in the last week a substantial troop and supply convoy has delivered its cargo to Rangoon, with a subsidiary re-supply operation boosting the defences in the Andamans.

Having recently taken delivery of six mine laying support tenders, the Imperial Navy has been busily engaged in distributing its minelayers throughout the Empire to lay fields first in principal traffic centres and thereafter in the outposts judged to be at greatest threat. In the case of Attu this has been combined with a re-supply operation that should leave this Aleutian outpost impregnable to anything but a major multi-divisional effort.

In the submarine war, the month has seen the loss to the Allies of two modern boats: Trigger and Grayling. An I-boat or two has received some damage, but none likely to lead to a sinking. Our styles of undersea warfare couldn’t be more different: those of my boats tasked with anti-merchantman operations stay well away from surveillance by patrol aircraft, whilst my opponent is content to station his boats in the immediate vicinity of my bases, accepting the risk that operations in shallow water entails. I’m not convinced this is his best tactic, but he is, of course, having to operate under considerable handicaps so far as transit times are concerned, as well as the difficulty of reaching my main SLOC’s without risking passage of such dangerous waters as the Malacca Straits. Furthermore, any convoy of note that he encounters is invariably accompanied by an ASW group, and my sub chasers and patrol craft are now starting to rack up more respectable experience levels. For my part, I’ve had a couple of successes against the Seattle-Dutch Harbor run, having located and sunk two large tankers during the month. Even my two auxiliary cruisers Aikoku Maru and Hokoku Maru had a notable success on 7 July, catching freighter Dakotan sailing independently 650 miles due east of Auckland and sinking her together with her cargo of Tomahawk fighters.

7 July was a particularly good day for the Japanese, as it also saw the fall of Wenchow and eradication of the last Chinese resistance east of Nanchang. But most of the action in China – and indeed the entire war – has been taking place in the south of China.

A month or so ago powerful Chinese forces began to move south-east from Wuchow along the left bank of the Pearl River. Not wishing to be overwhelmed by superior Chinese manpower, the Japanese manning the blocking positions outside Canton fell back inside the city’s defences, to be followed by the Chinese. The Chinese forces also established a blocking position of their own to the NW of Canton, no doubt intended to frustrate any Japanese attempt to get athwart their supply axis from Wuchow. The Chinese move has, of course, has shut down industrial activity in Canton; not a critical loss, but one the Japanese lacked the muscle to prevent with the bulk of CEA committed elsewhere.

Way back in the war’s early days Chinese forces had staged a brief incursion into Indochina. Presumably they didn’t rate their chances against what were then the modest defences of Hanoi/Haiphong, and retreated into the forests SW of Nanning, there to establish yet another blocking position. The Japanese enjoyed the bonus activation of four Viet Minh militia divisions, two of which established a blocking position of their own in the same forest, assisted by 31 Infantry Division, whilst the defences of Hanoi and Haiphong were built up.

Rather than slugging it out with the Chinese defenders in the forest, the Japanese plan has been to bypass them by a movement along the clear coastal terrain to Pakhoi, and for this purpose the Japanese brought in forces of significant strength from the Philippines and beyond, under the control of 14th Army. The object has been to secure, by the capture of Pakhoi, a substantial forward logistics base from which a further offensive into the interior via Nanning can be sustained, thus capitalising on Japan’s control of the sea. Not only should this permit the development of an effective offensive against Nanning, but, if that prospers, the threat of a thrust either in the direction of Tuyun, or along the right bank of the Pearl River with a crossing south of Wuchow that would isolate the Chinese forces investing Canton.

The first assault at Pakhoi went in on 21 July:

Ground combat at Pakhoi

Japanese Shock attack

Attacking force 83066 troops, 499 guns, 168 vehicles, Assault Value = 1587

Defending force 15175 troops, 63 guns, 0 vehicles, Assault Value = 477

Japanese engineers reduce fortifications to 3

Japanese max assault: 1401 - adjusted assault: 1378

Allied max defense: 514 - adjusted defense: 597

Japanese assault odds: 2 to 1 (fort level 3)

Japanese Assault reduces fortifications to 3

Japanese ground losses:
345 casualties reported
Guns lost 9
Vehicles lost 2

Allied ground losses:
852 casualties reported
Guns lost 20


One more attack was required, and it was mounted on 26 July after a respite for the attackers to recover and restock:

Ground combat at Pakhoi

Japanese Shock attack

Attacking force 83127 troops, 494 guns, 168 vehicles, Assault Value = 1584

Defending force 14135 troops, 39 guns, 0 vehicles, Assault Value = 425

Japanese engineers reduce fortifications to 2

Japanese max assault: 1445 - adjusted assault: 2334

Allied max defense: 457 - adjusted defense: 566

Japanese assault odds: 4 to 1 (fort level 2)

Japanese forces CAPTURE Pakhoi base !!!

Japanese ground losses:
355 casualties reported
Guns lost 13

Allied ground losses:
748 casualties reported
Guns lost 18

Defeated Allied Units Retreating!
(into Nanning)

The Chinese clearly regarded this as the writing on the wall, as they began (probably immediately) to withdraw from their blocking position in the forest SW of Nanning. Observing, on 29 July, that only one rearguard unit remained to man the block, the Japanese ordered an assault upon it for the following day, but the rearguard slipped away during the night, and the 31st Division and its militia comrades must now pursue as best they may.
