Paladin, I didn't know that the Yamato/Musashi group was coming back to Medan for a third consecutive night. the RN TF was part of a rotation to protect the troops at Medan. (A few days back, CA Quincy led some destroyers against four of the best Japanese CAs, and came out on top.) I did know that if Yamato and friends returned for a third consectuve night, the BBs would likely be low on ammo. Damage and slow them down and they face an ambush by SBDs and Avengers based at Langsa. I've already seen what RN and RAN cruisers can do to Japanese battleships. A month back, John lost two, with a third badly damaged, up at Akyab under similar circumstances - and Avengers there applied the coup-de-grace.
I completely understand guarding your troops and remember the beatdown that Quincy administered, hence why I say I don't have a problem fighting in a situation where you're outgunned. My view, now influenced by the fact that I know now why the Devonshire couldn't have been moved out, was that it seemed that you'd sacrificed a valuable CA for no real return on investment. Given that I know now that you were guarding your beachhead, I understand your actions better and while I still hate to see a CA lost, the knowledge of what you were protecting shifts the math back in your favor, especially if you're able to capitalize on the damage by pouring on the hurt with those SBD and TBM squadrons.
As for the hurt that you laid out on the IJN BBs a few weeks before, I'd point out that battle took place in almost perfect conditions to maximize the Allied advantages of radar and air power while minimizing the IJN's advantages of firepower and armor. I'd also note that those other BBs weren't the Yamato twins. I'd only feel somewhat confident in taking on those two with either a similar number of Allied fast BBs, extreme levels of SBDs and TBMs or 3:1 odds with the older Allied BBs. I may go 2:1 if I used the Colorados, New Mexicos or Tennessees, but that would not be my first choice.
