Are pirate lieutenants like navy lieutenants?
Lieutenant Richards was a pirate that sailed alongside Blackbeard. Lieutenant RIchards had many duties and was placed in charge of the ship, Bonnet's Revenge. In the Royal Navy and Commonwealth navies, the second-in-command of a vessel is known as the first lieutenant. Royal Navy lieutenants are in charge of other crew members and have many duties.
