“I love all the work you’re doing on submarines and the subgirls! How do I learn about how submarines sink ships?”
Er, plenty of places. Silent Service is really meant to be an introductory thing to get you interested in this kind of stuff, and I’m really happy that you’re thinking about real-life history.
You can go find old charts and books, or you can go online. Honestly places like Fleetsubmarine is a good place to start. The Pampanito museum is good as well. HYPERWAR also have some very good documentation that’s kind of dry.
I’ll update when I get back home later today. It’s been really busy these days IRL.
