General at Sea Robert Blake was an important naval commander of the Commonwealth of England and one of the most famous English admirals of the 17th century. His successes have been considered to have "never been excelled, not even by Nelson" according to one biographer.

Despite this, due to deliberate attempts to expunge the Parliamentarians from history following the Restoration, Blake's achievements tend to remain unrecognized.
