Japanese Fleet Sorties Sept-Oct 1943

Post by Carl Schwamberger » 10 Oct 2023 00:48

Searching for Sources Again.

During September - November 1943 Admiral Koga suspected the USN was executing some sort of operation in the central Pacific. What his intel people were seeing was then preparations for Operation GALVANIC. They were unsure of the date or target, but knew something was up. I've seen in the books remarks about elements of the Japanese fleet sortieing to interdict a invasion fleet in one or more directions. However these references are very vague on dates, courses, and number ships and types sent out. Can anyone refer me to a source with these details? Im trying to reconstruct the nuts and bolts of Kogos Hei plans for countering a enemy thrust into the Central Pacific. Just the date/s would be helpful.

Domo and Arrigato in advance for any help here.

Thanks very much. What are the best sources for this information?

Given the ship types, numbers, and possible speed of the sorties Im guessing fuel consumption was 'large'. These sorties also contrast with the weak response when Operation GALVANIC was executed in November. I suspect that was in part due to the fresh round of destruction of the fleet air arm in the upper Solomons late October. That of course would not affect the deployment of the submarines, did manage some attacks of the assorted USN TF.
