The book "Dead Wake: The Last Crossing of the Lusitania" by Erik Larson discusses the tragic sinking of the Lusitania during World War I, highlighting various strategic military decisions made by the belligerent nations. One significant point is Britain's extensive submarine fleet, which outnumbered Germany's, yet was primarily tasked with coastal defense rather than targeting enemy merchant vessels. This strategic choice reflected the broader military priorities of the British Navy at the time.

This emphasis on coastal defense rather than offensive operations suggests that Britain may have missed opportunities to disrupt German shipping and was more focused on protecting its own shores. The implications of these decisions played a crucial role in the events leading up to the Lusitania disaster, showcasing the complexities of naval warfare during the war.
