Who decided whether an ill Jellicoe stayed aboard

Did Admiral Tryon have a duty to put an ill John Jellicoe ashore?

The decision was not Tryon's alone: the ship's doctor, other officers, period medical assumptions, and Jellicoe's own wishes all mattered.

A modern duty-of-care formula does not map neatly onto the period. The ship's doctor and other officers would have shaped the decision before it reached Admiral Tryon. Contemporary medical advice could also regard clean sea air as beneficial, making continued care aboard seem like the least bad option. Jellicoe himself may have resisted going ashore because leaving his post offered no guarantee that he would regain it.
