The Red Flag was flown at Spihead, at least, but nobody could accuse the Spithead Mutineers of Red Revolution.Details as to why this flag was chosen are unclear, there is some thought it was there to remind all that dicipline still existed, and that the fleet would have put to sea if the French had sailed - buts thats conjecture.
Red Flags were also flown by Pirates and Rovers, as a sign of surrender or else. Hence the Jolly Roger ( a mistranslation from Jollie Rouge)
The 'Hermoine' mutinied at Sea, in Carribean Waters.
