September 26 - Operation Oswald, mixed results
Most of my ships were sighted yesterday, outside Nauru. But not all. Still, he runs in 3 Es and 2 DDs, all with torpedoes. They do contact my CV TFs... [:-] Later in the war, I will have to be more careful. I had extensive search up from Ontong over the past week, with Catalinas, and had CV planes searching out 10 hexes. I think these guys came from the Mili area, but I can't be certain. Other, more significant assets (CAs and up) were known to be elsewhere on the map.

Damage is 8 major float and nothing to the engines, so she's off to Pearl in the near future but I'll use her for a few more things first.
And then I-10 puts a torpedo into CA Baltimore and it isn't good. I try to send her to Sydney, but she gets sunk later by another sub. The only major loss in the whole operation.
Elsewhere, Sculpin sinks an AK without an escort outside Truk. Bueno.
During the day's air phases, various air raids on my TFs. Eventually my CAP gets worn out, but it's too late for it to benefit him any. In future, I'll have more decks available and this hopefully won't be an issue.

I think his pilot quality among Betty/Nell pilots is suffering at this point. He must have lost so many - over 250 Bettys lost to A2A and AAA alone, with another 250 of G3M2/G3M3 lost to the same.
During the day, 54x 4Es and CV pilots bomb the crap out of Nauru, getting ~700 reported casualties amongst the defenders. We also bomb Ocean Island a bit.
Ground combats - Nauru falls, and Tassafaronga units finally wipe themselves out.
