The Jolly Roger

Lieutenant Commander (later Admiral Sir) Max Horton first flew the Jolly Roger-two flags in fact- on return to harbour after sinking the German cruiser Hela and the destroyer S-116 in 1914; but the Black Flag of old-time pirates was not generally flown by submarines, to show their successes, until the Second World War.
