ORIGINAL: CaptHaggard

Gentlemen,

The first flotilla of 8 submarines set off from Midway this morning, their thin line on the far horizon soon casting a somber vision, despite whoops of jubilation when lines were singled-up... in the next five days, similar flotillas of vessels will depart Midway and Wake, Rabaul and Shortlands, 14 flotillas in all, numbering over 100 submarines...

Over the last months, reconnaissance submarines have plied gaps between Japanese-held islands, veritable fissures in their dreams of world conquest, trying to find routes into the Philippine Sea that elude detection; others have tested the grey areas at the limits of enemy search-radii to the west and south; all this in an effort to reach deployment areas without raising enemy alarm.

It is hoped these vessels will soon gather in strange interludes for a day or two, poised to spread in all directions from their silent deployments, to blossom into a veritable shield encrusting the Marianas as the invasion armada enters into the waters east of Rota: 108 6-hex triangular patrol zones, in some approaches 6 patrol zones deep.

The brave submariners, first into enemy waters, fully know that Admiral Bravo is set sail with an extraordinary force, no doubt occasionally unwieldy by its colossal proportions, inexperienced, uncertain, course set for a target so distant that anything contemplated in Europe is dwarfed in comparison... this wild-eyed operation, so long planned, is now exhilarating and heroic.

We don't know what we'll find at journey's end—but soon, at least—the first casualty will be speculation.

Good luck, Rio!

—R.R. Haggard, Commander, USN



Commander Haggard-

Good hunting!

Your pal,

-Terry

Lowpe-

I am pleased that you are following The War College and that you are looking forward to the Allies invading the four southern Marianas Islands mid June, 1943.

I am curious as to what El Lobo has on the Marianas Islands and I am curious as to whether he will send his Carriers to fight at the Marianas Islands.

If he sends his Carriers to fight, rather than sinking Japanese Carriers, I hope to kill as many Japanese pilots as possible.

Best Regards,

-Terry

Wolfhunter-

I am pleased that you are following The War College.

Considering the present date of the War and considering that I haven't a clue what El Lobo has on the Marianas Islands, I scraped and scrounged and bought out as many available ground force units as possible.

The Canadians are responsible for capturing Rota. The New Zealanders are responsible for capturing Tinian.

In two to three days, I will set forth the entire Order of Battle for Operation Sea Shark. At that time, you will no doubt be pleased to see how many Canadian and New Zealand Infantry Brigades and supporting troops are involved with Operation Sea Shark.

Best Regards,

-Terry

Operation Sea Shark
Invasion of the Four Southern Marianas Islands
Order of Battle
As of June 8, 1943



Opening Comments


Since the inception of the war, the Allies have planned to invade Saipan, Tinian, Rota, and Guam (the four southern Marianas Islands) during the month of June, 1943. Operation Sea Shark is an integral part of the Allied Grand Strategy to implement a Naval Blockade of Japan Proper and to transport ground forces, aircraft, and supply to China in support of Operation Land Shark (the land war to conquer Burma, China, Manchukua, and Korea).


Consolidated Data


Excluding the Submarines, Minesweepers, and PT boats under the Command of Captain Haggard, the Invasion Fleet is comprised of the following:

• 3,120 Miles from Pearl to Objectives
• 427 Wildcat Fighters
• 271 Hellcat Fighters
• 134 Dauntless Dive Bombers
• 46 Task Forces
• 971 Ships
• 20 Carriers
• 23 Battleships
• 25 CAs
• 26 CLs
• 7 CLAAs
• 95 Destroyers
• 22 AOs
• 262,310 Fuel Replenishment
• 1,943 Saipan Assault Value
• 788 Tinian Assault Value
• 703 Rota Assault Value
• 3,131 Guam Assault Value
• 337,339 Saipan Supply
• 331,106 Tinian Supply
• 330,480 Rota Supply
• 622,657 Guam Supply
• 1,621,582 Total Supply
• 14,000,000 Rolls of Toilet Paper


Task Forces


I have no doubt, that many of The War College members could have done a much better job creating the Invasion Fleet Task Forces. It has been a time consuming and daunting task configuring the following Task Forces:

Also make sure to put some combat ships into amphib TFs as shell magnets and suppression especially in Saipan case because of naval fortress CD unit. For suppression puproses combat ships work much better in amphib compared to separate bombardment TFs. Bombardment on the other hand can go in and out.

Status: offline 		I also suggest that you eventually put the CVEs into about 2-3 separate TFs, each with < 150 aircraft and a few DDs and DEs; they can sit right in the coastal hex under assault and operate at full capacity. You want to keep your fast carriers with 30 knt cruiser and DD escorts one hex out to sea where they will still put a lot of cap over the adjacent island, and also will possibly divert the attention of the IJN away from your transports, or at least attract the airstrikes so your Hellcat jocks can go to work. This separation will make best use of the aircraft under the 1943 co-ordination limit.

I see you have the California and the Tennessee in twice (in bombardment groups and SAGs) - If they are going to act as SAG protection, do not let them shoot off all their ammo in a bombardment. The 5 fast USN BBS, and the Prince of Wales would either go with the fast carriers, or are formed into a surface SAG with the most aggressive and capable leader available (use Ching Lee or Arleigh Burke if they're out there in command of a TF) and also retain their full ammo load in case Mr Yamato and his buddy Mr Musashi drop by. It won't be pretty if your air cover doesn't deter them, and you might lose a couple of your new BBs, but at least they'll be damaged and go away. The Repulse is better off doing AAA duty with the fast carriers, where it might take a torpedo instead of a CV.

On a related note, looking at your Replenishment Group - your fuel state looks good, but where are the AEs and AKEs to reload your BBs and cruisers? (Hopefully loaded and dispersed amongst the supply taskforces to be separated later.) I'd be going for Rota, or whichever island looks to have the weakest garrison, first, to establish a resupply lagoon with some of those big AEs that can transfer 16" rifle ammo. I'd also have a flotilla of ARs/ADs ready to go to Guam to operate with the 7th fleet HQ ASAP.

And the usual advice about putting some BB float planes on recon (night and day), and some cruiser floatplanes on night activities.

Ian R—

The AE and AKEs are heading from PH to Midway tomorrow. They will be ready to go to Wake to rearm the BBs and CAs, or—depending on their perceived vulnerability as the battle progresses—remain in Midway for the task.

The "usual advice" from you and all the other gentlemen of War College is not only welcome but essential. Kindly keep it coming!

Thank you!

—Hag

Wake is too far away in an emergency. A small, two ship AE & AKE task group with an ASW escort might escape detection in the clutter, and give you the ability to rearm about 2-3 BBs overnight at the first anchorage you occupy. Those numbers are an anecdotal observation. I've never done the maths, but there was a post years ago that said its coded so that the smaller ships will load from the smallest AKE with capacity to rearm them, leaving your Lassen class AE to attend to the big fellows. It also means you can rotate rearmed bombardment groups across to the other islands where the situation on the ground may still be in issue. Just remember to reload the AEs from the port on any day they aren't otherwise engaged.

Hopefully this will all be moot because your Guam attack force is bigger than any historical (Pacific) landing force bar Okinawa. If the number crunching says the Guam port size plus the naval HQ & the nav support in all the various BFs adds up to the right amount, you may be able to rearm most ships there anyway, although probably still needing a large AE for the 14" -> 16" rifles.

GetAssita-

Your interest in The War College and your sage advice is appreciated.

One or Two Waves of Amphibious Landings?

It has been previously discussed within The War College as to whether ground and naval losses would be greater with one wave or two waves.

One wave should result in ground forces unloading quicker, thereby giving the Japanese coastal guns and aircraft less opportunity to hammer Allied troops and ships than two waves.

However, as you indicate, two waves should result in less losses to Headquarter units, Base Force units, and Construction units.

Considering that I haven't a clue what El Lobo has on the four southern Marianas Islands, that I don't know whether overall losses would be greater with one wave or two waves, and that I want to get the Invasion Fleet away from the Marianas Islands as soon as possible, I opted for one wave.

Do you feel strongly, considering the circumstances, that Allied over-all losses would be less with two waves (i.e., holding back the HQ units, Base Forces, and Construction units for the second wave)?

Capital Ships Imbedded with Amphibious Task Forces

I have imbedded one destroyer with each Amphibious Task Force.

I have enough destroyers to imbed two destroyers within approximately 20 of the Amphibious Task Forces which would leave 20 less destroyers for Combat Surface Task Forces. However, considering that I only plan to make one Bombardment run, the second day will free up four Bombardment Task Forces that I plan to convert to Surface Combat Task Forces.

Would you go with two DDs in as many Amphibious Task Forces as possible without lessening the strength of the one day Bombardment Task Forces?

Best Regards,

-Terry

What does sigint tell you about expected enemy forces?



Lowpe-

I haven't a clue regarding the Japanese strength at the Marianas Islands. The only intelligence I have is that yesterdays Signet Report indicated that the Japanese 24th Infantry Regiment had loaded and was bound for Guam.

The Allies have increased activity at Aitape, Manus, Kavieng, Rabaul, and the Shortlands with minimal ships and troops in an effort to divert El Lobo's attention away from the Marianas Islands. For over a month, the Signet Report has been indicating that El Lobo is transferring troops to Moluccas.

I haven't snooped around the Marianas Islands for fear of alerting El Lobo to an early impending Allied Invasion of the Marianas Islands.

Due to the early date of the war, I am gambling that El Lobo will not be expecting an Allied Invasion of the Marianas Islands, that the Allies will surprise him, and that he has not yet stuffed the Marianas Islands with troops and aircraft.

I have dedicated such a large force to capturing the Marianas for the following two reasons:

1.) To capture the Marianas Islands as soon as possible to build the ports, airbases, and forts.

2.) To have substantial ground forces in place at the Marianas to prep for the next major invasion which will be Formosa.

Best Regards,

-Terry

Ian R-

Thank you for your interest in The War College, bringing to my attention that I listed BB California and BB Tennessee in both a Bombardment Task Force and Surface Combat Task Forces, and for your sound advice.

Tomorrow, I will transfer BB California and BB Tennessee from the Surface Combat Task Forces 662 nd 670 to the Bombardment Task Force 532.

At the outset, for purposes of Operation Sea Shark only, I am not concerned about grouping fast combat ships together in a Task Force.

Briefly, the General Plan is as follows:

1.) The entire Invasion Fleet will slowly move together from Pearl Harbor to one hex due east of Rota.

2.) The Bombardment Task Forces will bombard only one night and return to one hex east of Rota. Upon their return, the Bombardment Task Forces will change their mission to Surface Combat.

3.) The Amphibious Task Forces will assault the beaches. After each unloads the troops and supply, the Amphibious Task Forces will return to one hex east of Rota.

4.) All the Carriers are presently intended to remain one hex east of Rota to protect the Bombardment Task Forces and Amphibious Task Forces. Carrier Aircraft Assignments are to be as follows:

-276 Hellcats will provide CAP over the hex due east of Rota.
-200 Wildcats will provide LRCAP over the target hexes of Saipan, Tinian, Rota, and Guam (i.e., 50 Wildcats per each of the four objectives).
-227 Wildcats will not be designated a target, but rather provide LRCAP covering 3 hexes.
-Each of the above fighter groups will vary their altitude at 20,000, 15,000, and 10,000 feet.
-134 Dauntless Dive Bombers will bomb the airfields at Saipan, Tinian, Rota, and Guam the day after the Bombardment Task Forces have bombarded those same Islands. After the Dauntless' one day bombing of airfields, their mission will change to Naval Attack.

5.) Upon all Bombardment Task Forces and Amphibious Task Forces returning to one hex east of Rota, together, the entire Invasion Fleet will slowly return to Pearl Harbor.

I have designed this plan as I believed that it was the best plan to accomplish the following goals:

1.) Provide the best protection possible for all ships.

2.) Hammer the four islands and airfields.

3.) Kill Japanese pilots.

4.) Capture the four southern Marianas Islands.

Coordination 1943 Limits?

However, if I am understanding you correctly, you are telling me that my orders for the aircraft will not happen as planned due to limits on "Coordination" in 1943 because I have too many carriers and too many aircraft in the same hex?

Further, that by splitting the carriers into smaller groups and in two hexes that the coordination of aircraft missions would be more successful?

Please clarify and advise.

Best Regards,

-Terry

Status: offline 		Terry, a few general ideas that seem to work well in practice:

1. I'm assuming you have some MSW or DMS integrated in your TFs. Including the bombardment ones. If you send an MSW task force into sweep Saipan, it will be sunk by the fortress guns. Dispersed in other TFs they will still sweep some mines, and the enemy has bigger fish to catch.

2. I'd put the assault troop transports into bigger TFs - right up to the 100 ship limit to saturate the defenses - even your attack transports will fire their 5" or 3" guns and it all helps. I would put the old Omahas in them at two per if possible to suck up the shore fire. Otherwise the CD guns will possibly shoot at each TF. If you have a bombardment BB that is down under 50% ammo, and you can't rearm it on site, you my as well include it, as the smaller CD guns will bounce a lot of rounds off its belt plate. If you have some amphib loaded AKAs with supply only, put some in the 100 ship TF to offload it direct to the troops.

3. Unless you have loaded the assault troops sparsely across a lot of ships, they will take at least 2-3 days to get all the combat elements ashore anyway. One days ground bombardment will give you the enemy OOB and tell you whether to use a shock attack to overrun the base or wait.

4. To get some recon results I'd set all the bombardment BB floatplanes to that mission, half at night*, along with any groups from cruisers embedded with the landing force. The other cruisers' and fast BBs' groups can do the naval searching and a bit of ASW. [*So they spot the shore bombardment as well.]

5. Last but not least - I gather you are planning to assault all 4 islands simultaneously, rather than starting, say, with Guam to establish a base under local air cover (200 Corsairs should do it) and working your way up with all the CVE and slow BB groups supporting each assault in turn, then replenishing. I think that's dangerous, because you are splitting your naval assets, but maybe it'll work given the surprise element. Because it will take a while to unload, and all 4 bases might not be taken in the first few days, I do think you need to be prepared to fight a fleet engagement - that means do not commit your fast carrier strike groups to base attacks, other than maybe one to port attack the CD guns. Also, keep at least a fast BB TF and a cruiser TF with full ammo loads to serially assault any IJN SAGs that sneak in at night.

And break out the PT boats.

Edit: The above was typed before I saw your last post and some of it is redundant.

The aircraft coordination rule is buried on page 167 of the manual. In 1943, the chance of (allied) co-ordination loss is doubled if the number of aircraft in the CVTF is greater than 150 +rnd(150). Obviously two CV TFs have just under a 1/3rd risk of coordination loss, but you can tailor your CVE TFs more precisely.

The other rule I was thinking of is at the foot of page 167, but it only applies if the carrier is "in a base hex" as opposed to in a TF in a base hex. I had a notion that CVEs didn't suffer the 50% launch penalty, but on reflection this is irrelevant.

Also, have a look at 6.3.5 on page 129 - once your bombardment TFs have any ship with <33% ammo load, they will disobey orders and head back to Pearl Harbor - another reason to set up your first island conquest as their TF home base and replenishment point, so they will be located there the next morning instead of half way to Wake Is.

As to point #1—In running a couple of Marianas invasions in a mini-game, my experience in ordering everything at once into the invasion hexes (as Admiral Bravo intends) resulted in the MS TFs and the Bombardment TFs predictably encountering first fire—but with MS losses in mines only, not from CD fire, even against that bad boy at Saipan. The CDs seemed always to concentrate on the Bombardment TFs, while the MS went about their business (at least if the Bombardment TF had a BB firing)...

Losses were pretty steep for the MS TFs because the islands have a ton of mines (in the juiced-up mini-version).

Here the MS TFs have between 12-20 ships for each invasion, all containing a combination of DMS, AM & YMS... IOW, everything I could lay my hands on

Thank you for your excellent points!

—Hag

Opening Comments



1.) The Sea Shark Invasion Fleet is two hexes southwest of Laysan Island at hex 163,97; 2,280 miles from its destination one hex due east of Rota near the Marianas Islands.

2.) I am beginning to get a tad concerned that Chungking may indeed fall into Japanese hands sometime during the next few months as El Lobo's bombers are inflicting heavier casualties than in the past.


Synopsis of Combat Events for Today


1.) Captain Haggard's AM hits El Lobo's submarine I-38 five times near Midway (hex 153,101).

2.) El Lobo bombs Chungking.

3.) El Lobo deliberately attacks near Kienko (hex 79,41) and near Chungking (hex 79,39).

4.) The Allies deliberately attack Ramree Island.

Commander Cody-

Welcome aboard The War College!

Thank you for wishing Captain Haggard and I success in capturing the four southern Marianas Islands.

I have previously been advised numerous times not to mix slow carriers nor slow combat surface ships with fast carriers and fast combat surface ships. However, for the purposes of Operation Sea Shark only, I don't understand the relevancy considering the following:

1.) Except for the Bombardment and Amphibious Assault Task Forces, the Allies intend to keep the entire Invasion Fleet together in the same hex to and from Pearl Harbor and at the hex due east of Rota. After the Bombardment Task Forces bombard each of their objectives only one time (i.e., Saipan, Tinian, Rota, and Guam) and after the Amphibious Task Forces unload troops and supply, the Bombardment Task Forces and Amphibious Assault Task Forces will return to join the Invasion Fleet.

2.) The Allies do not intend to neither chase nor run from Japanese warships. The Invasion Fleet carriers intend to provide CAP and LRCAP in an effort to protect the Amphibious Assaults and kill Japanese pilots. The Invasion Fleet Combat Surface Task Forces intend to remain in the same hex as the carriers and returning Amphibious Assault Task Forces to fight any Japanese war ships that care to enter the hex.

3.) The Allies simply do not care about speed. When the Invasion Fleet moves, it will move at 12 knots, the speed of the slowest transports within the Invasion Fleet. Neither the carriers nor the combat surface ships will break-away from the Invasion Fleet as their mission is to protect hundreds of transports.

Accordingly, for the purposes of Operation Sea Shark only, am I missing something?

Best Regards,

-Terry

Revision of Order of Battle

for

Operation Sea Shark Task Forces

June 10, 1943



Upon taking into consideration the recent sage advice of GetAssista and Ian R, the Allies have decided to make the following changes regarding some of Operation Sea Shark's Invasion Fleet Task Forces:

1.) Carrier Task Forces will be revised to assure that no single Carrier Task Force contain more than 150 aircraft nor more than 15 ships.

2.) One BB and one CA will be removed from each of the four Bombardment Task Forces.

3.) Three new Surface Combat Task Forces will be formed, using the removed BBs and CAs, and using the all the surface combat ships presently in the three Surface Combat Task Forces.

4.) One day prior to the Amphibious Assaults, the Amphibious Assault Task forces will be revised to include up to 100 Amphibious Assault transports, thereby reducing the number of transports the Japanese Coastal Guns can fire upon.

Within a day or two, I will post the complete revised Operation Sea Shark Order of Battle.

Best Regards,

-Terry

pontiouspilot-

You Canadians do make me laugh.

In response to your question: Like the man that fell out of his 16th floor apartment responded to those below that asked how things were going as he passed by on the way down, "So far, so good."

Only two of the present 46 Task Forces of the Invasion Fleet indicate detection, both at a detection level of 1.

Captain Haggard reports that his submarines 200 miles north of Wake Island are being detected at higher levels.

Our ships moving into Wake Island have also been snooped fairly well for about three weeks.

Accordingly, I suspect that as the Invasion Fleet passes 40 miles above Wake Island the freight train will be heard.

Best Regards,

-Terry

Rio Bravo: By speed, as far as I know (and I'm no developer), ships are easier to hit the lower their speed (which matches the lowest speed in the TF). By that I mean the faster the ship, the harder it is to hit it with bombs, torpedoes or naval shells.

I could be wrong, but somewhere along the way this got stuck in my head and I keep it in mind when organizing TFs.

Opening Comments


The Operation Sea Shark Invasion Fleet is proceeding together slowly at 12 knots and is 2,040 miles away from its destination one hex due east of Rota near the Marianas Islands. The Disruption Level of the troops is close to 6 and the Fatigue Level is 0.


Synopsis of Combat Events for Today


1.) El Lobo Bombs Chengtu and Chungking. El Lobo's bombers are taking a heavy toll on the heavily battered and bruised Chinese at Chungking. The Chinese Assault Value at Chengtu is 2,700 and the Fort Level is 1. The Assault Value at Chungking is 5,100 and the Fort Level is 5. The Chinese are severely low on supply and running out of rubber bands to shoot at El Lobo's evil marauding pillagers and plunderers.

2.) El Lobo deliberately attacks near Kienko at hexes 79,41 and 79,39. El Lobo attacks the Chinese at these two hexes nearly everyday and has been for a couple months. The brave and honorable Chinese have beaten off each attack by hurling rocks and swinging sticks.

3.) The 2nd British Division attacked Ramree Island for the fifth (maybe the sixth) time today and once again was denied the prize. Damn Ramree and the El Lobo wave it surfed in on!

Commander Cody-

That makes sense.

Unfortunately, the Allies can't risk leaving hundreds of transports unguarded.

Besides, after laying-low for eighteen months, the troops are itching to fight.

Best Regards,
