How would an earlier destruction of Beatty's battlecruiser force change the war and Jutland?
Short answerIt would likely centralize the fleet under Jellicoe, speed replacement construction, and may improve Britain's tactical position at Jutland.
NotesBritain would probably replace the lost scouting function with other battlecruisers and accelerate delayed capital-ship work. The disaster would also vindicate Jellicoe's objections to operating the battlecruisers as a detached force. A unified Grand Fleet might therefore approach Jutland without the historical runs south and north, and with the Fifth Battle Squadron positioned differently. Germany would enter the battle with its fast force intact, yet tighter control under Jellicoe could produce a better British tactical outcome despite the earlier loss.
