The Submarine in War and Peace: Its Development and its Possibilities

The text explains the mechanical principles and evolution of submarines, recounting pioneer inventors' experiments and the author's own designs, illustrated with technical diagrams and case studies. It describes operational practices—diving, periscopes, propulsion, torpedoes—and evaluates submarine employment in war, countermeasures and the challenges of detection and defeat. It also explores peacetime and commercial applications such as cargo recovery, hydrographic work, and underwater salvage, and considers industrial, political, and strategic implications for navies and commerce. Historical anecdotes, technical explanation, and forward-looking analysis combine to assess the vessel's capabilities, limitations, and likely future roles.
