This is the second volume of a Trilogy dealing with Anglo-German naval affairs and conflict before and during the First World War. The first volume dealt with the period leading up to the outbreak of hostilities, and the role the German Navy played in ensuring that Great Britain would be progressively alienated and eventually, reluctantly, driven into the enemy camp. This account deals with the period of the subsequent naval conflict that, bar Jutland, contained most of the significant surface engagements of the Great War. It describes the battles of the Heligoland Bight, Coronel, Falkland Islands, and the Dogger Bank action. It also covers the stunning first impact of the submarine on the whole concept of naval warfare. As a volume, it encompasses the naval administration of those two titans, Churchill and Fisher, whose personalities dominated the period and whose triumphs and disasters are at the heart of the story.
