Could a decisive Royal Navy victory at Jutland, followed by forcing the Baltic, prevent the February Revolution?
Short answerIt might end the war early enough to help, but the interval before February 1917 could still be too short to supply and stabilize Russia.
NotesA much more complete British victory at Jutland could shorten the war, perhaps ending it in 1916. Opening or dominating the Baltic might also increase the strategic pressure on Germany. The timing remains the problem: the February Revolution follows early in 1917, leaving little margin to deliver enough supplies and stabilize Russia. A naval victory could therefore help create the necessary conditions without guaranteeing that relief reaches the empire in time.
