How could replacement commanders fight Jutland differently with knowledge of the historical battle?
Short answerThey should repair communications, use aerial scouting, keep the Fifth Battle Squadron connected, cut across the German scouts, and lead the enemy toward a fully informed Grand Fleet; advance warning also allows gunnery and ammunition reforms.
NotesReplacing Beatty, the first priorities would be a reliable communications chain, retained seaplane carriers, and a slower advance that kept the Fifth Battle Squadron integrated. The tactical aim would be to strike across the First Scouting Group, withdraw through supporting battleships, and report continuously to the Grand Fleet commander. A few hours of warning would not repair unsafe shell handling across the fleet. Six months would allow battlecruiser squadrons to rotate through Scapa Flow for gunnery training and safer ammunition practices. Better reconnaissance and communications could then turn the encounter into a deliberate trap rather than another confused chase.
