“An absorbing work for those interested in both the Great War and early submarine-based strategic theory.” —Naval History This deeply researched and engaging account of the use of U-Boats in the First World War focuses on both diplomatic and economic aspects as well as the tactical and strategic use of the U-boats. The book also examines the role played by US president Woodrow Wilson and his response to American shipping being sunk by U-boats—and how that ultimately forced his hand to declare war on Germany. Includes photos and illustrations “An excellent illumination of a multiclass, militaristic, and diplomatically inept state trying to adapt to the realities of modern war and the exploitation of new technology—and catastrophically failing.” —Naval History “Highly recommended.” —The Northern Mariner
