Where Reginald Henderson might have commanded in wartime

Which major fleet might Reginald Henderson have commanded during the Second World War?

The Mediterranean Fleet or a Far Eastern command are the plausible choices, with the latter offering the more revealing test against Japan.

The proposed appointment is a reasoned counterfactual rather than a prediction. Reginald Henderson's experience makes the Mediterranean Fleet or a Far Eastern command the most plausible choices. He might have performed comparably to Andrew Cunningham in the Mediterranean. The Far East offers the more revealing test because it raises the question of how Henderson would have managed the Royal Navy's confrontation with Japan.
