Interesting scenario and one so frequently found in history but never in games. Well done!
Lately, I’ve been dipping my toes into Napoleonic naval fiction. (Very little impresses me after O’Brian, buy hey, what’s a guy to do?) Are you familiar with the Alexander Clay books by Philip Allan? Enjoyable reads. I just finished book 4 with a fog scenario in it and was kind of wrapping my head around how to replicate it on the table.
