Re: Last battle between sailing vessels
Royal navies (US, Brit, Dutch, French, and Spanish) had certain rules of engagement.
For example: if two ships are approaching the one that is seeking to make aggression can run up another nations colors to pretend to be an ally. They just have to run up their real colors before they fire. Also, it was looked at as cowardice to signal your vessel was in need of asisstance as a ploy to lure an enemy in among just a few of the "rules."
