Fortunately, the Jolly Roger was accompanied by contemporary labels detailing its provenance.
“It is my belief that the Jolly Roger in Brighton museum is a success flag from Unbeaten - but not her actual patrol Jolly Rodger” David J.B. Smith
To many, this may not be a big deal. However, this indicator of the submarines successes during World War Two has laid undiscovered for seventy-six years. Among historians and researchers it was considered that this flag was lost during the Blitz. This webpage will detail the story of Unbeaten's Jolly Roger and the many replicas spawned by its supposed disappearance. The symbology used on Unbeaten's Jolly Roger will also be explained followed by a short history of the Royal Navy submarine Jolly Roger.
All that remains for me is to re-write a chapter in my book about HMS Unbeaten - Being Silent They Speak
