William Fisher combined tactical, intelligence, and logistics experience

Fisher had commanded the First Battle Squadron, directed Naval Intelligence, served as Fourth Sea Lord for supply and transport, and held senior Mediterranean, training, and Portsmouth appointments. He was especially associated with night fighting, while sharing Henderson's support for large destroyers and naval air power. His staff roles also taught him how to frame naval requirements for ministers rather than merely state a professional case. That combination of tactical authority, administrative range, and political experience underpins the claim that Fisher would probably have become First Sea Lord instead of Roger Backhouse.
