AFTER ACTION REPORTS FOR Oct 10, 43
Two area to concentrate on today , Rabaul and Java. However I would like to say a thank you to PzB
for coming round to visit last Sunday, it was great with beer and curry all round ! Not to mention 2
free books [;)]. And yes i did get some handy tips.
Anyhoo , on with the AAR
Rabaul ..
From a recent communication with USN HQ in the SW Pacific " we have a plan for Rabaul and the 2 BB's there.
Could you place the small Dutch SCTF under US command for a few days ? " OFC the admiralty had no option
to agree with the USCV'c operating for the British near Java. The response from the Dutch commander is
unknown. (don't think anyone asked them ). Admiralty sources now state that the 'plan' is completely unknown
to our staff and the whole thing is the USNs responsibility. Australians agreed to cooperate and placed
LR torp attack a/c in range of Rabaul if called for and P47's in NG sent on a sweep mission to assist.
At midnight on 10th Oct the radios sprang to life with reports of multiple US subs hitting mines in Rabaul harbour.

Improved night sighting under 89% moonlight
Then the USN surprised the main japanese force and utterly botched the attack ,, high moonlight levels
mean they engaged from longer range and that helped the large BB guns immensly. and also hampered
USN escape attempts , Some damage was inflicted but not much.

Then Daylight arrived and the small Dutch CL led TF was surprised to see 2 large shapes on the

commander did not know and sadly we will never find out as hit flagship was destroyed by
heavy shell fire along with one DD.

The expected ground attack from Japan was a division sized unit and allied air did indeed manage to
hurt it badly and allowed the Australian brigade to hold (for now) .. losses were heavy among the

Artillery should arrive tomorrow with 2 more brigades and some light armour en-route.
The second wave has unloaded in Tjiljap and been sent out to designated targets. Also we will trade
shellfire with the heavy jap defenders north of Tjiljap and see what's here. The CV's are to pull back and rearm
in Christmas island.
I hope tomorrow is nice and quiet in Java , although the bombers are still heading into ground attack duty.
