Why judge Troubridge and Arbuthnot differently when Troubridge held an independent command and Arbuthnot only led a squadron?
Short answerTroubridge's freedom was limited by direction from London, while Arbuthnot acted with less effective supervision and might have benefited from senior intervention.
NotesErnest Troubridge commanded an independent force, while Robert Arbuthnot led a cruiser squadron in the Grand Fleet. Formal independence did not tell the whole story because Troubridge was receiving persistent direction from London. Arbuthnot had less immediate supervision when he made his disastrous choice, and stronger intervention from senior command might have restrained him. The comparison links command failure to an officer's judgement and the supervision or staff system around him.
