Castles Of Steel by Robert K. Massie

Britain, Germany, and the Winning of the Great War at Sea

A sweeping narrative of the naval dimension of World War I that traces the prewar Anglo-German naval arms race, the strategic and tactical struggles between surface fleets and the rise of submarine warfare, and how events such as the Battle of Jutland, the German unrestricted U-boat campaign, the British blockade, and the adoption of convoys shaped the course and outcome of the conflict at sea; through operational detail and profiles of key commanders it shows how mastery of the oceans helped determine the wider war and the eventual Allied victory.
