Using an array of archival materials from Britain, Germany, and the United States, The War for England's Shores examines why the Germans failed to make the most of this opportunity to disrupt the British war economy. G. H. Bennett analyzes how the British slowly nullified the threat by embracing new technologies and developing a system of sea control to gradually force the German S-Boat arm to transition from offensive action against Britain's coastal convoys to the defensive posture of waiting for an invasion of France. Considering the war along Britain's coastal convoy routes in the context of twenty-first-century interest in littoral warfare, this work has vital, current appeal using the German S-Boat campaign of 1940 to 1945 to offer significant and surprising new insights.
