CA Chokai begins game in some small covering TF, of ONE CA, and ONE DD. It is supposed to escort Invasion TF, but this invasion is not supposed to happen in next two weeks.
However, I have found, that Chokai was actually part of Close Support Force for Malaya, and it was in:
4 December 1941: Operation "E" - The Invasion of Malaya:
CHOKAI, CruDiv 7, SubRon 5's light cruiser YURA, eight destroyers and four submarines depart Samah as part of the close support force for the seizure of Malaya. Operates off Cap Camau, Indochina then Camranh Bay.
CL Yura begins game in Japan...
So, anyone knows, what were names of those 8 DDs? I would like to put this TF.
