More timeline format stuff, should be one more of these and then I should be close enough to do slightly more detailed writeups and some plans for January.

14th- Landings at Ternate.
14th- SAG based around CA Nachi engages group of 5 US DD's during the day in the Makassar Strait, with inconclusive results. DD Hatsuyuki develops a severe fire after a single hit.
14th- Second SAG around CL Teshio engages the same group of DDs, leaving several ablaze and badly damaged. DD Fubuki takes 4 shells and heavy damage, but remains afloat for now.
14th- Mini-KB fails to strike at surviving DDs, instead sinking three HDMLs near Tarakan.
14th- Attack on Ambon comes off as a 1-5 due to 'leaders', and it turns out that commanding officer of the 1st Kure Assault Division doesn't know which end of the rifle should be pointed at the enemy. There will be day of rest and leadership 'reassignment' before the next attack.

CA Nachi and escorts get a bloody nose.

CL Teshio and escorts give a better showing, though CV strikes fail to catch any of the cripples.
