R Go

Post by rjl3 » 24 Dec 2023 20:48

I have been looking into the Invasion of Rabaul in January 1942. Unfortunately there does no seem to be a definitive source suck as Frank's Guadalcanal so I have been trying to piece this together from several, often conflicting, sources. From what I have seen several ships stated to have been a part of this invasion did not take part (Kyo 8, Kyo 10, Shuko), and several others not listed actually did take part (Seikai).
I did not find Japanese designations for the various component convoys so for convenience I numbered them in order by date of departure.
Looks like there were too many ships to be accomodated only at Woleai so refueling was done enroute at Woleai and Lamotrek Atolls.
As always any comments, correction, or addition info most welcome.

Convoy !. Departed Truk on Jan 11. arrived Woleai / Lamotrek area on Jan 15.
Kaijo # 2 Maru

Tama (264 tons)
Tama 8
Toshi 3
Convoy 5. Departed Woleai area on Jan 17. arrived Rabaul on Jan 22. consisted of all the ships that had stopped here previously.
Convoy 6. Departed Truk on Jan 20. arrived Kavieng Jan 23.

Kikutsuki
Kinryu
Tatsuta
Tenryu
Uzuki

Convoy 7. Departed Kavieng on Jan 25g, arrived Rabaul on Jan 25g. same ships as Convoy 6.

This was a lot of work to put together and I have no doubt there are many errors. Would love to see a graphical chart of these movements!

Tsugaru, Okinoshima and Tenyo Maru are part of convoy 2.
Mogamigawa Maru was scheduled to take part in the invasion but was probably removed on 16 January 1942 because she was to be converted into an aircraft transport.
Tokiwa unclear to me at the moment in which of the convoys she may have been.

Mitsuki is typo for Mutsuki.

Berend, thank you for pointing out the minelayers participation. I was't sure whether they were acting independently or escorts for the main convoy.
Tokiwa was running around Kwajalein and the Marshall Islands around this time and may or may not have participated.

The main convoy was carrying the South Seas Detachment mainly consisting of 144 Inf Reg. I think there was a naval unit also - a SNLF?
I do not know what units went to Kavieng first.

I did not list the Main Cover force with carriers, etc yet.

I started with R Go but it is my intention to document the follow-on south expansion R convoys. There is some confusion on the invasion names. So far I have
RE
RI
RS Lae - note not MO
RY Nauru
RXC Buka
RWH Shortland
RXB Tulagi

Convoy 2 apparently went to Truk and departed there for Rabaul on 23 January. Does it match your data or have you ruled it out as conflicting data?

Here is probably all the information you need:

It will need to be translated with Google Translate or, if you use Google Chrome web browser,
it will translate it to english for you seamlessly.
