How might a much more decisive British victory at Jutland have affected later naval treaties and the war?
Short answerIt could have enabled Baltic operations and sharper pressure on German supply, potentially changing the war before treaty questions arose.
NotesDestroying much of the High Seas Fleet at Jutland could have made a British light-force blockade of Germany's Baltic coast practical. Access to Russian Baltic ports might then have allowed supply convoys during 1916, before the 1917 revolution. Those possibilities could change Russia's position and the duration of the war before any postwar treaty negotiations began. Denying Germany Baltic imports from Sweden, Denmark and neighbouring areas would also put pressure on its war economy. Peacetime industrial capacity is a poor guide to wartime output when skilled workers have been mobilised into the army. In this interpretation, the loss of imports would compound that labour problem. The proposed consequences remain conditional on the scale of the British victory and the operations that followed.
