Strategic stakes behind fusing the Grand Fleet

On this reading, Churchill's famous warning about Jellicoe was incomplete because Reinhard Scheer also commanded a fleet capable of deciding the war in an afternoon. Destruction of the Grand Fleet could expose Britain to a German surface blockade, while destruction of the High Seas Fleet could let Britain enter the Baltic and choke Germany's remaining supply routes. Those stakes explain why Jellicoe could not tolerate collisions, signal confusion, or captains who executed orders without thinking. At Jutland his ships maneuvered without the organizational failures that could have ruined the deployment, evidence of the training imposed beforehand. The institution itself had only been created after George Callaghan's abrupt removal in August 1914, which Jellicoe disliked. He then had to fuse Home and Channel Fleet elements while operating in the North Sea, sustaining the blockade, and improving the inadequate base at Scapa Flow.
