The Battle of Jutland was the greatest naval engagement of the First World War, if not any war. Admiral Scheer had adopted a policy of launching attacks against the British coast. What he did not know was that the British had broken his naval codes and that they knew of his plans. Consequently, when Scheer threw his entire fleet in a mission to attack the British mainland in May 1916, he could not know that the Royal Navy at Scapa Flow were underway.This is a fresh account of this greatest naval engagement, it offers fascinating insight into the events preceding the action, the tactics during the battle and the political and military fall-out. The book draws on released official records and personal accounts.Jellicoe failed to ensnare Scheer and the bulk of the German fleet which escaped battered, but intact. The Germans knew however that despite their great fleet, it was the Royal Navy that controlled the North Sea.
