This book covers the activities of the French and British in the Mediterranean, the Italians and Austrians in the Adriatic, and the Russians, Germans and Turks in the Baltic and Black Seas. Detailing the Royal Navy's campaign against the German raiders, the colonial campaigns and the major overseas expeditions, the author examines not only naval operations, but leadership, policy, strategy, tactics and technology and relates these to the wider political, diplomatic and economic aspects of the war. The author also covers lesser-known conflicts such as the Rumanian campaign and the Danube flotillas, as well as the historic battles of Jutland, the Dardenelles and the anti-submarine warfare.
