Submarine Warfare, Past, Present, and Future

In Short

This book provides a panoramic history of submarine development, tracking the transition from primitive diving bells to the sophisticated, torpedo-bearing submersibles of the early twentieth century. It functions as both a technical primer and a social history, examining the engineering hurdles—such as propulsion, steering, and compass interference—alongside the fierce debates regarding the morality of "invisible" warfare. By documenting the failures and breakthroughs of pioneering inventors, the work captures the pivotal moment when the submarine began to shift from a dismissed curiosity into a vital, if controversial, pillar of modern maritime power.

The Story

The narrative begins with a clear mission: to demystify a subject long obscured by public ignorance and naval conservatism. The early chapters establish the historical context, positioning the submarine as the spiritual successor to ancient methods of subaqueous sabotage. We are introduced to the long, often tragic lineage of inventors who sought to conquer the depths—from the ill-fated Mr. Day, who perished in his own experimental market-boat, to the sophisticated designs of the late nineteenth century. The text argues that the submarine’s development mirrors that of the torpedo, noting that both were initially dismissed by "fossilised officials" as the desperate weapons of the weak, only to be grudgingly accepted once their efficacy became undeniable.

As the argument progresses, the focus shifts to the intense rivalry between major powers, particularly the tension between Great Britain and France. The author meticulously details the French enthusiasm for "submersibles," which many of their admirals viewed as a viable alternative to the costly construction of massive battleships. We see how these small, stealthy vessels—such as the Gustave Zédé—were used in exercises to humiliate superior surface fleets, famously firing simulated torpedoes at high-ranking officials while they dined aboard a battleship. These anecdotes serve to illustrate the psychological impact of underwater warfare; the ability to strike unseen threatened not just the steel of a ship, but the very prestige of the reigning naval powers.

The final arc of the book deals with the practical realities of the "submarine age." The narrative moves away from theoretical posturing to address the brutal engineering limitations of the time: the unreliability of compasses in metal hulls, the dangers of internal engine vibration, and the harrowing, claustrophobic nature of life inside a submerged boat. The author concludes by weighing the arguments of contemporary humanitarians who debated whether such "deadly engines" would make war so horrific that it would cease to occur, or merely introduce a new, untraceable form of terror to the seas. The book ends not with a final victory for the submarine, but with a sober recognition that the technology is now firmly entrenched, and that the future of naval conflict will be irrevocably shaped by the silent, hidden maneuvers of the diving boat.

How It Unfolds

The legacy of the past The book opens by cataloging the scarcity of existing literature on submarines, establishing the author’s intent to provide a popular guide for the lay reader. It traces the concept of underwater attack back to sixteenth-century engineers, setting the stage for a long history of trial and error.

The struggle for recognition The narrative examines the intense prejudice faced by early inventors from established naval authorities. It highlights how powerful institutions resisted the submarine, fearing that such weapons would undermine the traditional dominance of the battleship.

Technical hurdles The text shifts to the mechanics of submersion, detailing the complex balance of ballast, rudders, and propulsion. It explains why early boats were dangerously unstable and how inventors struggled to compensate for the erratic behavior of compasses in enclosed metallic spaces.

The French experiment The focus turns to the French Navy’s adoption of submersibles and their aggressive test maneuvers. This section highlights the tactical shift toward "guerre de course" and the terrifying potential of invisible vessels to evade detection by even the most vigilant signal stations.

The future outlook The final beats assess the integration of the submarine into modern fleets. It concludes by reflecting on the inevitable nature of technological progress, suggesting that even the most conservative nations would eventually adopt the very weapons they once labeled illegitimate.

The People

The book is populated by a cast of visionaries, skeptics, and engineers whose competing agendas define the era. Mr. Day, the "unhappy sacrifice to his own ingenuity," represents the amateur spirit of early exploration; he seeks glory and profit, only to be undone by a complete lack of scientific preparation. Robert Fulton serves as the quintessential frustrated inventor, a man who sees the potential to render traditional fleets obsolete but finds himself thwarted by a commission of skeptical, status-quo-defending politicians.

Then there are the naval figures like Admiral Aube and Admiral Sir J. C. Dalrymple Hay, who represent the stark divide in military ethics. Aube advocates for the radical, total destruction of enemy ports, viewing the submarine as a means to force a nation to its knees. In contrast, figures like Vice-Admiral Bourgois stand as the voice of restraint, arguing that even in the age of the torpedo, the basic laws of humanity—such as verifying a ship’s nationality and protecting non-combatants—must remain in force. Finally, the inventors Nordenfelt and Drzewiecki act as the pragmatic bridge to the future, obsessively iterating on designs for horizontal stability and surface propulsion. They want to prove that the submarine is not a mere toy for defense, but a reliable, offensive machine capable of changing the geography of naval power.

In Its Own Voice

The following passage highlights the common, often humorous, resistance to new technology, noting how the public eventually adopts what it once feared:

"Just as many old ladies have been heard to declare that they will never travel by the Two-penny Tube, so nations have been known to disclaim all intention of using particular weapons."

Regarding the dangerous instability of early vessels, the author provides a vivid example of how easily a minor mistake could lead to disaster:

"It has been said that one man going forward in a submarine boat would cause her to dive to a depth of thirty-six feet in one minute."

Describing the stealthy, almost ghostly success of the Gustave Zédé during French naval trials, the author notes:

"Its presence was shown above water only by the tiny tricolour flag, the size of a sheet of paper, just above the surface."

What It's Really About

This book is a study of the friction between technological innovation and institutional inertia. It explores the central question of whether a nation can maintain its strength by clinging to traditional forms of power, or if it must embrace "illegitimate" weapons to survive. The work examines the paradox of military progress: the idea that the more terrifying a weapon becomes, the more likely it is to enforce a strange kind of peace. Beyond the mechanics of the submarine, the book probes the morality of war, questioning where to draw the line between a strategic advancement and a violation of the laws of nature. It ultimately argues that fear of the unknown is the primary obstacle to progress, and that the "fossilised" mind is the greatest danger in any military evolution.

Why Read It Today

This book is essential reading for anyone interested in the history of technology or the slow, often agonizing path of military reform. It offers a rare, ground-level view of an era where "submarine" was still a subject of debate rather than a staple of naval power. Readers will find the author’s voice engaging, warm, and refreshingly unburdened by modern hindsight; he writes as someone witnessing a sea change in real-time.

You will appreciate the book for its vivid, human details—the "headaches" experienced by guests on early test voyages, the absurdity of an inventor writing to a gambling enthusiast to fund his projects, and the genuine sense of wonder that surrounds these early machines. However, be prepared for the book's period-specific attitudes; the author writes from a distinctively British imperial viewpoint, and his focus is fixed on the naval rivalries of the early 1900s. The text can be technically dense in its descriptions of engine types and ballast tanks, and the prose reflects the formal, sometimes wordy style of the Edwardian era. Yet, for all its occasional dryness, the book leaves you with a profound sense of the vulnerability of the men who first descended into the deep, and a clear understanding of how the invisible, silent dangers of the ocean floor became a permanent fixture of our world.
