Mostly started this to keep myself on track of this massive life sucking undertaking labeled as a PC game.

We will see how active this will be, most likely reporting main events or planning for the future by picking the brains of people smarter than me.

Hawaii Operation 12/07/41

IJN

Combined Fleet

1st Fleet
6th Fleet





1st Mobile Fleet attacked Pearl Harbor with 5 carriers as it was newly organized just before this operation.

First Carrier Division (Akagi)
Second Carrier Division (Shōkaku, Zuikaku)
Third Carrier Division (Hiryū, Sōryū)

2nd Mobile Fleet is being built around the Fourth Carrier Division (Kaga, Ryūjō)


The attack was iniated by the Special Attack Unit but none could penetrate the harbor defenses.

COMBAT EVENTS FOR 12/07/41

I-16 launches midget submarine Ha-22 to attack Pearl Harbor
SSX Ha-22 hits obstruction and is lost attempting to penetrate harbor at Pearl Harbor
I-18 launches midget submarine Ha-24 to attack Pearl Harbor
SSX Ha-24 founders and is lost attempting to penetrate harbor at Pearl Harbor
I-20 launches midget submarine Ha-14 to attack Pearl Harbor
SSX Ha-14 hits a mine and is destroyed at Pearl Harbor
Midget Sub Ha-18 lost during attempted launch from I-22 at Pearl Harbor
I-24 launches midget submarine Ha-19 to attack Pearl Harbor
SSX Ha-19 hits a mine and is destroyed at Pearl Harbor


I am pretty happy with the PH air strike, this was a compromise of different variations:

4x DB Sq dive bombed the airfields
1x DB Sq dive bombed the port
3x TB Sq level bombed the port
2x TB Sq attacked with torpedoes.

Fighters where purely for escort, I know they could have helped take out more ac but KB needs to keep up a high operational tempo for the moment so did not risk it.



BB Maryland blew up, something else also went down based on the sinking sounds during the turn resolution.

I hope it could be the CA San Francisco, many of the damaged ships got critical hits from the level bombers that exploded inside.

25 Army, 5 Division, Carp(鯉兵団), 1 Tank Rgt and support elements landed at Singora.

Their orders are to advance towards Georgetown and the western coastal road.

The Imperial Guards Division and the 14 Tank Rgt are being transported to Singora trough Thailand by rail.
They are held in reserve and preparing for the Singapore assault operation, they will be the first to cross Johore.


Elements of the 18 Division, Chrysanthemum (菊兵團), landed at Kota Bharu, IR 56 and 12th Engineer Regiment, IR 55 and IR 112 of the 18 Division and the 6 Tank Rgt are held in standby at Cam Ranh Bay.

Also available for Malaya are the separate I/II/III of IR 124 at Cam Ranh.

IJN will support the landing with additional shore bombardments and JAAF by ground bombing.

JAAF 3 Air Division support units are preparing to land in Khota Baru in a few days but will be diverted to Patani to prepare that AF in case Kota Bharu is not taken as planned.

If IR 56 takes Kota Bharu, next landing will be prepared to Kuantan after the airfield at Kota Bharu is operational and IJN is ready to support.

Rest of the 25 Army will concentrate around the Saigon-Cam Ranh Bay area and most will travel to Malaya by rail.

Priority is given to the JAAF 3 Air Division movement over to the Malayan peninsula to free up the JNAF 22 Air Flotilla to support the Borneo and Sumatra operations.

Both JAAF and JNAF covered the landings with CAP, JAAF also sweeped and hit the airfields in central Malay.
Minimal and sporadic response from the RAF, most exciting incident was when CA Mikuma took a hit.

14 Army, elements of the 48 Division, Sea (海兵団), Kanno and Tanaka Detachments, artillery and JAAF support and engineers will land in the first wave to Aparri.

Rest of 48 Division will land also in Northern Luzon in the following days and advance towards Clark Field.
65 Brigade, reinforced with some artillery, will also land in Aparri to secure the JAAF AF build up and act as an vanguard towards Manila.

16 Division, Wall (垣兵団) is in transit to Pescadores where it will prepare to also land on Northern Luzon.

16 Army, in Palau, will plan for landing in Southern Luzon with elements of the 2 Division,Courageous(勇兵団), main body of the division is still in transit in to the AO.

38 Division will join 16 Army after the Hong Kong Operation and coordinate its landing in Southern Luzon with the 2 Division.

That lunatic MacArthur and his colonial mercenaries must be made an example and annihilated, he has already manipulated the Filipinos against the Greater East Asia Co-prosperity Sphere, all of Asia is watching.



JNAF bombing mission to Manila did not launch, Takao AF was crowded, cleared some ac away, JNAF will try a night strike against Manila port.

The AAR format is forming up, keep it simple, stupid!

I am happy to answer if someone has requests related to Combat Reports that I have not posted, questions related to OOB, operations, tactics or strategies I have not yet shared.
