Excerpts from Books and Wikipedia
"Beginning on May 31, 1916, Admiral Sir John Jellico, commanding the Royal Navies Grand Fleet, fought the only fleet action of World War I against the German Imperial navy, commanded by Admiral Reinhard Scheer. . . . Kaiser Wilhelm II proclaimed a great victory. Indeed the battle had not produced the decisive results that the British, heirs to the traditions of Nelson and Trafalgar, had expected. . . . Jutland had ensured that the British would retain their strategic and psychological dominance of the North Sea for the remainder of World War I." [Furtado: 1001 Days]
