About the HMS Thanet, it's confirmed. It's the ship that scored the last torpedo hit on the Ise, which was probably the last significant damage. It was bombed by a B-17 while it was getting patched up, but I don't think the bomb did that much damage due to the ship's armor.
I'm going to do something out of character and ask my opponent about the fate of this ship.

He says the Ise is safely in Japan for repairs. Damn.
