If Hood replaced Beatty at Jutland, would Britain still lose three battlecruisers?
Short answerPossibly, but Hood's stronger communications could bring the fleet action earlier and give Jellicoe more options, changing where the battlecruisers were exposed.
NotesHood's presence would change the flow of information before it changed any survival calculation. His reputation as an active communicator suggests that Jellicoe could receive better reports, bring the main fleet action forward, and deploy with clearer information. Earlier contact would alter the positions and exposure of the British battlecruisers. Their losses would still be possible because the three historical casualties remained the weakest ships in the force.
