Welcome! One thing, regarding your question to Dan on the HMS Terror: I could be mistaken but don't be surprised if he doesn't answer your question, as I believe he regards directed questions to him on the forums as inappropriate or not customary, at least.
Ok! Thank you for the information! The question was initially meant for anyone who'd read The Terror, but I was very unclear about that! I've edited it so it conveys the intended audience. Again, thanks for helping me recognize how ambiguous I was before.
