Midget Submarines 1939-45

"Midget Submarines 1939-45" by Ingo Bauernfeind offers a focused examination of one of the more specialized and often overlooked categories of naval warfare during the Second World War. Published as part of Osprey's New Vanguard series, this compact volume covers the design, development, and operational history of small submarines used by various navies throughout the conflict, providing readers with a concise but informative overview of a niche subject that rarely receives dedicated treatment in broader naval histories.

The book examines midget submarines developed and deployed by multiple nations, including Germany, Italy, Japan, and Britain. Each navy approached the concept differently, shaped by their strategic circumstances, industrial capabilities, and tactical requirements. Bauernfeind traces how these vessels evolved from experimental prototypes into operational weapons, highlighting the engineering challenges involved in creating submarines small enough for covert operations yet capable of carrying meaningful offensive payloads. The technical descriptions are handled with clarity, making the material accessible even to readers without a background in naval engineering.

One of the strengths of this work lies in its comparative approach. Rather than focusing exclusively on a single nation's program, the author places different midget submarine designs side by side, allowing readers to appreciate the variety of solutions engineers pursued when faced with similar constraints. The German Biber and Seehund classes, the Italian human torpedoes and their associated craft, the Japanese Ko-hyoteki types used at Pearl Harbor, and the British X-craft used against the Tirpitz all receive attention, illustrating how different strategic contexts produced distinct technological responses.

The operational history sections are particularly valuable, as they place these vessels within the context of specific missions and campaigns. The attack on Pearl Harbor, though often remembered primarily for the role of Japanese aircraft carriers, also involved midget submarines, and the book provides useful context on their contribution and ultimate fate during that operation. Similarly, the British attacks on the German battleship Tirpitz using X-craft are covered, demonstrating how these small vessels could be employed against high-value targets that conventional submarines might struggle to approach undetected.

As with other titles in the New Vanguard series, this book benefits from extensive visual material, including photographs, technical diagrams, and specially commissioned artwork. These illustrations help readers visualize the cramped internal layouts and unusual design compromises that characterized midget submarine construction. Given the relatively obscure nature of many of these vessels, the visual documentation adds considerable value, allowing readers to understand design features that might otherwise remain abstract when described in text alone.

The format of the series, with its emphasis on concise, well-organized information, suits this subject matter well. Midget submarines represent a specialized area of naval history, and a lengthy academic treatment might not have been the most effective approach for introducing general readers to the topic. Instead, Bauernfeind provides enough technical detail to satisfy those with a serious interest in naval engineering while maintaining readability for those approaching the subject for the first time.

The book also touches on the strategic reasoning behind midget submarine programs, explaining why various navies invested resources in developing these unconventional weapons. Factors such as limited industrial capacity, the need for asymmetric tactics against superior naval forces, and the desire to conduct covert operations against protected harbors all contributed to interest in this type of vessel across different combatant nations.

Overall, this volume serves as a solid introduction to midget submarines during the Second World War. It successfully balances technical detail with historical narrative, providing readers with both the engineering context and the operational significance of these unusual vessels. For those interested in naval history, particularly the more unconventional aspects of underwater warfare, this book offers a useful starting point. While it may not satisfy readers seeking exhaustive technical specifications or deeply detailed operational accounts, it fulfills its purpose as an accessible overview of a specialized subject that deserves more attention than it typically receives in mainstream naval histories. The combination of clear writing, useful illustrations, and balanced coverage across multiple national programs makes this a worthwhile addition for anyone curious about this particular chapter of wartime naval innovation.
