The rank of General at Sea (occasionally referred to as General of the Fleet), was the highest position of command in the English Parliamentary Navy (later the Navy of the Commonwealth of England, Scotland and Ireland), and approximates to the current rank of Admiral. Alongside others, the Generals at Sea were also appointed as Commissioners for the Admiralty and Navy. The Generals at Sea were referred to both by the title of 'General' and by their former army ranks interchangeably. Today, the title 'Admiral' is also commonly – if incorrectly – used.
